.. index:: encoder
Encoders
========
This section gives an overview of encoders, details on the encoders
that ship with libxo, and documentation for developers of future
encoders.
Overview
--------
The libxo library contains software to generate four "built-in"
formats: text, XML, JSON, and HTML. These formats are common and
useful, but there are other common and useful formats that users will
want, and including them all in the libxo software would be difficult
and cumbersome.
To allow support for additional encodings, libxo includes a
"pluggable" extension mechanism for dynamically loading new encoders.
libxo-based applications can automatically use any installed encoder.
Use the "encoder=XXX" option to access encoders. The following
example uses the "cbor" encoder, saving the output into a file::
df --libxo encoder=cbor > df-output.cbor
Encoders can support specific options that can be accessed by
following the encoder name with a colon (':') or a plus sign ('+') and
one of more options, separated by the same character::
df --libxo encoder=csv+path=filesystem+leaf=name+no-header
df --libxo encoder=csv:path=filesystem:leaf=name:no-header
These examples instructs libxo to load the "csv" encoder and pass the
following options::
path=filesystem
leaf=name
no-header
Each of these option is interpreted by the encoder, and all such
options names and semantics are specific to the particular encoder.
Refer to the intended encoder for documentation on its options.
The string "@" can be used in place of the string "encoder=".
df --libxo @csv:no-header
.. _csv_encoder:
CSV - Comma Separated Values
----------------------------
libxo ships with a custom encoder for "CSV" files, a common format for
comma separated values. The output of the CSV encoder can be loaded
directly into spreadsheets or similar applications.
A standard for CSV files is provided in :RFC:`4180`, but since the
format predates that standard by decades, there are many minor
differences in CSV file consumers and their expectations. The CSV
encoder has a number of options to tailor output to those
expectations.
Consider the following XML::
% list-items --libxo xml,pretty
<top>
<data test="value">
<item test2="value2">
<sku test3="value3" key="key">GRO-000-415</sku>
<name key="key">gum</name>
<sold>1412</sold>
<in-stock>54</in-stock>
<on-order>10</on-order>
</item>
<item>
<sku test3="value3" key="key">HRD-000-212</sku>
<name key="key">rope</name>

This output is a list of `instances` (named "item"), each containing a
set of `leafs` ("sku", "name", etc).
The CSV encoder will emit the leaf values in this output as `fields`
inside a CSV `record`, which is a line containing a set of
comma-separated values::
% list-items --libxo encoder=csv
sku,name,sold,in-stock,on-order
GRO-000-415,gum,1412,54,10
HRD-000-212,rope,85,4,2
HRD-000-517,ladder,0,2,1
Be aware that since the CSV encoder looks for data instances, when
used with :ref:`xo`, the `--instance` option will be needed::
% xo --libxo encoder=csv --instance foo 'The {:product} is {:status}\n' stereo "in route"
product,status
stereo,in route
.. _csv_path:
The `path` Option
~~~~~~~~~~~~~~~~~
By default, the CSV encoder will attempt to emit any list instance
generated by the application. In some cases, this may be
unacceptable, and a specific list may be desired.
Use the "path" option to limit the processing of output to a specific
hierarchy. The path should be one or more names of containers or
lists.
For example, if the "list-items" application generates other lists,
the user can give "path=top/data/item" as a path::
% list-items --libxo encoder=csv:path=top/data/item
sku,name,sold,in-stock,on-order
GRO-000-415,gum,1412,54,10
HRD-000-212,rope,85,4,2
HRD-000-517,ladder,0,2,1
Paths are "relative", meaning they need not be a complete set
of names to the list. This means that "path=item" may be sufficient
for the above example.
.. _csv_leafs:
The `leafs` Option
~~~~~~~~~~~~~~~~~~
The CSV encoding requires that all lines of output have the same
number of fields with the same order. In contrast, XML and JSON allow
any order (though libxo forces key leafs to appear before other
leafs).
To maintain a consistent set of fields inside the CSV file, the same
set of leafs must be selected from each list item. By default, the
CSV encoder records the set of leafs that appear in the first list
instance it processes, and extract only those leafs from future
instances. If the first instance is missing a leaf that is desired by
the consumer, the "leaf" option can be used to ensure that an empty
value is recorded for instances that lack a particular leaf.
The "leafs" option can also be used to exclude leafs, limiting the
output to only those leafs provided.
In addition, the order of the output fields follows the order in which
the leafs are listed. "leafs=one.two" and "leafs=two.one" give
distinct output.
So the "leafs" option can be used to expand, limit, and order the set
of leafs.
The value of the leafs option should be one or more leaf names,
separated by a period (".")::
% list-items --libxo encoder=csv:leafs=sku.on-order
sku,on-order
GRO-000-415,10
HRD-000-212,2
HRD-000-517,1
% list-items -libxo encoder=csv:leafs=on-order.sku
on-order,sku
10,GRO-000-415
2,HRD-000-212
1,HRD-000-517
Note that since libxo uses terminology from YANG (:RFC:`7950`), the
data modeling language for NETCONF (:RFC:`6241`), which uses "leafs"
as the plural form of "leaf". libxo follows that convention.
.. _csv_no_header:
The `no-header` Option
~~~~~~~~~~~~~~~~~~~~~~
CSV files typical begin with a line that defines the fields included
in that file, in an attempt to make the contents self-defining::
sku,name,sold,in-stock,on-order
GRO-000-415,gum,1412,54,10
HRD-000-212,rope,85,4,2
HRD-000-517,ladder,0,2,1
There is no reliable mechanism for determining whether this header
line is included, so the consumer must make an assumption.
The csv encoder defaults to producing the header line, but the
"no-header" option can be included to avoid the header line.
.. _csv_no_quotes:
The `no-quotes` Option
~~~~~~~~~~~~~~~~~~~~~~
:RFC:`4180` specifies that fields containing spaces should be quoted, but
many CSV consumers do not handle quotes. The "no-quotes" option
instruct the CSV encoder to avoid the use of quotes.
.. _csv_dos:
The `dos` Option
~~~~~~~~~~~~~~~~
:RFC:`4180` defines the end-of-line marker as a carriage return
followed by a newline. This `CRLF` convention dates from the distant
past, but its use was anchored in the 1980s by the `DOS` operating
system.
The CSV encoder defaults to using the standard Unix end-of-line
marker, a simple newline. Use the "dos" option to use the `CRLF`
convention.
The Encoder API
---------------
The encoder API consists of three distinct phases:
- loading the encoder
- initializing the encoder
- feeding operations to the encoder
To load the encoder, libxo will open a shared library named:
${prefix}/lib/libxo/encoder/${name}.enc
This file is typically a symbolic link to a dynamic library, suitable
for `dlopen`(). libxo looks for a symbol called
`xo_encoder_library_init` inside that library and calls it with the
arguments defined in the header file "xo_encoder.h". This function
should look as follows::
int
xo_encoder_library_init (XO_ENCODER_INIT_ARGS)
{
arg->xei_version = XO_ENCODER_VERSION;
arg->xei_handler = test_handler;
return 0;
}
Several features here allow for future compatibility: the macro
XO_ENCODER_INIT_ARGS allows the arguments to this function change over
time, and the XO_ENCODER_VERSION allows the library to tell libxo
which version of the API it was compiled with.
The function places in xei_handler should be have the signature::
static int
test_handler (XO_ENCODER_HANDLER_ARGS)
{
...
This function will be called with the "op" codes defined in
"xo_encoder.h". Each op code represents a distinct event in the libxo
processing model. For example OP_OPEN_CONTAINER tells the encoder
that a new container has been opened, and the encoder can behave in an
appropriate manner.

FAQs
====
This section contains the set of questions that users typically ask,
along with answers that might be helpful.
General
-------
Can you share the history of libxo?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In 2001, we added an XML API to the JUNOS operating system, which is
built on top of FreeBSD_. Eventually this API became standardized as
the NETCONF API (:RFC:`6241`). As part of this effort, we modified many
FreeBSD utilities to emit XML, typically via a "-X" switch. The
results were mixed. The cost of maintaining this code, updating it,
and carrying it were non-trivial, and contributed to our expense (and
the associated delay) with upgrading the version of FreeBSD on which
each release of JUNOS is based.
.. _FreeBSD: https://www.freebsd.org
A recent (2014) effort within JUNOS aims at removing our modifications
to the underlying FreeBSD code as a means of reducing the expense and
delay in tracking HEAD. JUNOS is structured to have system components
generate XML that is rendered by the CLI (think: login shell) into
human-readable text. This allows the API to use the same plumbing as
the CLI, and ensures that all components emit XML, and that it is
emitted with knowledge of the consumer of that XML, yielding an API
that have no incremental cost or feature delay.
libxo is an effort to mix the best aspects of the JUNOS strategy into
FreeBSD in a seemless way, allowing commands to make printf-like
output calls with a single code path.
Did the complex semantics of format strings evolve over time?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The history is both long and short: libxo's functionality is based
on what JUNOS does in a data modeling language called ODL (output
definition language). In JUNOS, all subcomponents generate XML,
which is feed to the CLI, where data from the ODL files tell is
how to render that XML into text. ODL might had a set of tags
like::
tag docsis-state {
help "State of the DOCSIS interface";
type string;
}
tag docsis-mode {
help "DOCSIS mode (2.0/3.0) of the DOCSIS interface";
type string;
}
tag docsis-upstream-speed {
help "Operational upstream speed of the interface";
type string;
}
tag downstream-scanning {
help "Result of scanning in downstream direction";
type string;
}
tag ranging {
help "Result of ranging action";
type string;
}
tag signal-to-noise-ratio {
help "Signal to noise ratio for all channels";
type string;
}
tag power {
help "Operational power of the signal on all channels";
type string;
}
format docsis-status-format {
picture "
State : @, Mode: @, Upstream speed: @
Downstream scanning: @, Ranging: @
Signal to noise ratio: @
Power: @
";
line {
field docsis-state;
field docsis-mode;
field docsis-upstream-speed;
field downstream-scanning;
field ranging;
field signal-to-noise-ratio;
field power;
}
}
These tag definitions are compiled into field definitions
that are triggered when matching XML elements are seen. ODL
also supports other means of defining output.
The roles and modifiers describe these details.
In moving these ideas to bsd, two things had to happen: the
formatting had to happen at the source since BSD won't have
a JUNOS-like CLI to do the rendering, and we can't depend on
external data models like ODL, which was seen as too hard a
sell to the BSD community.
The results were that the xo_emit strings are used to encode the
roles, modifiers, names, and formats. They are dense and a bit
cryptic, but not so unlike printf format strings that developers will
be lost.
libxo is a new implementation of these ideas and is distinct from
the previous implementation in JUNOS.
.. index:: XOF_UNDERSCORES
.. _good-field-names:
What makes a good field name?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To make useful, consistent field names, follow these guidelines:
Use lower case, even for TLAs
Lower case is more civilized. Even TLAs should be lower case
to avoid scenarios where the differences between "XPath" and
"Xpath" drive your users crazy. Using "xpath" is simpler and better.
Use hyphens, not underscores
Use of hyphens is traditional in XML, and the XOF_UNDERSCORES
flag can be used to generate underscores in JSON, if desired.
But the raw field name should use hyphens.
Use full words
Don't abbreviate especially when the abbreviation is not obvious or
not widely used. Use "data-size", not "dsz" or "dsize". Use
"interface" instead of "ifname", "if-name", "iface", "if", or "intf".
Use <verb>-<units>
Using the form <verb>-<units> or <verb>-<classifier>-<units> helps in
making consistent, useful names, avoiding the situation where one app
uses "sent-packet" and another "packets-sent" and another
"packets-we-have-sent". The <units> can be dropped when it is
obvious, as can obvious words in the classification.
Use "receive-after-window-packets" instead of
"received-packets-of-data-after-window".
Reuse existing field names
Nothing's worse than writing expressions like::
if ($src1/process[pid == $pid]/name ==
$src2/proc-table/proc-list
/prc-entry[prcss-id == $pid]/proc-name) {
...
}
Find someone else who is expressing similar data and follow their
fields and hierarchy. Remember the quote is not "Consistency is the
hobgoblin of little minds", but "A *foolish* consistency is the
hobgoblin of little minds". Consistency rocks!
Use containment as scoping
In the previous example, all the names are prefixed with "proc-",
which is redundant given that they are nested under the process table.
Think about your users
Have empathy for your users, choosing clear and useful fields that
contain clear and useful data. You may need to augment the display
content with xo_attr() calls (:ref:`xo_attr`) or "{e:}"
fields (:ref:`encoding-modifier`) to make the data useful.
Don't use an arbitrary number postfix
What does "errors2" mean? No one will know. "errors-after-restart"
would be a better choice. Think of your users, and think of the
future. If you make "errors2", the next guy will happily make
"errors3" and before you know it, someone will be asking what's the
difference between errors37 and errors63.
Be consistent, uniform, unsurprising, and predictable
Think of your field vocabulary as an API. You want it useful,
expressive, meaningful, direct, and obvious. You want the client
application's programmer to move between without the need to
understand a variety of opinions on how fields are named. They
should see the system as a single cohesive whole, not a sack of
cats.
Field names constitute the means by which client programmers interact
with our system. By choosing wise names now, you are making their
lives better.
After using `xolint` to find errors in your field descriptors, use
"`xolint -V`" to spell check your field names and to help you detect
different names for the same data. "dropped-short" and
"dropped-too-short" are both reasonable names, but using them both
will lead users to ask the difference between the two fields. If
there is no difference, use only one of the field names. If there is
a difference, change the names to make that difference more obvious.
What does this message mean?

.. index:: Field Formatting
.. _field-formatting:
Field Formatting
----------------
The field format is similar to the format string for printf(3). Its
use varies based on the role of the field, but generally is used to
format the field's contents.
If the format string is not provided for a value field, it defaults to
"%s".
Note a field definition can contain zero or more printf-style
'directives', which are sequences that start with a '%' and end with
one of following characters: "diouxXDOUeEfFgGaAcCsSp". Each directive
is matched by one of more arguments to the xo_emit function.
The format string has the form::
'%' format-modifier * format-character
The format-modifier can be:
- a '#' character, indicating the output value should be prefixed
with '0x', typically to indicate a base 16 (hex) value.
- a minus sign ('-'), indicating the output value should be padded on
the right instead of the left.
- a leading zero ('0') indicating the output value should be padded on the
left with zeroes instead of spaces (' ').
- one or more digits ('0' - '9') indicating the minimum width of the
argument. If the width in columns of the output value is less than
the minimum width, the value will be padded to reach the minimum.
- a period followed by one or more digits indicating the maximum
number of bytes which will be examined for a string argument, or the maximum
width for a non-string argument. When handling ASCII strings this
functions as the field width but for multi-byte characters, a single
character may be composed of multiple bytes.
xo_emit will never dereference memory beyond the given number of bytes.
- a second period followed by one or more digits indicating the maximum
width for a string argument. This modifier cannot be given for non-string
arguments.
- one or more 'h' characters, indicating shorter input data.
- one or more 'l' characters, indicating longer input data.
- a 'z' character, indicating a 'size_t' argument.
- a 't' character, indicating a 'ptrdiff_t' argument.
- a ' ' character, indicating a space should be emitted before
positive numbers.
- a '+' character, indicating sign should emitted before any number.
Note that 'q', 'D', 'O', and 'U' are considered deprecated and will be
removed eventually.
The format character is described in the following table:
===== ================= ======================
Ltr Argument Type Format
===== ================= ======================
d int base 10 (decimal)
i int base 10 (decimal)
o int base 8 (octal)

===== ============= ====================
.. index:: UTF-8
.. index:: Locale
.. _utf-8:
UTF-8 and Locale Strings
~~~~~~~~~~~~~~~~~~~~~~~~
For strings, the 'h' and 'l' modifiers affect the interpretation of
the bytes pointed to argument. The default '%s' string is a 'char \*'
pointer to a string encoded as UTF-8. Since UTF-8 is compatible with
ASCII data, a normal 7-bit ASCII string can be used. '%ls' expects a
'wchar_t \*' pointer to a wide-character string, encoded as a 32-bit
Unicode values. '%hs' expects a 'char \*' pointer to a multi-byte
string encoded with the current locale, as given by the LC_CTYPE,
LANG, or LC_ALL environment varibles. The first of this list of
variables is used and if none of the variables are set, the locale
defaults to "UTF-8".
libxo will convert these arguments as needed to either UTF-8 (for XML,
JSON, and HTML styles) or locale-based strings for display in text
style::
xo_emit("All strings are utf-8 content {:tag/%ls}",
L"except for wide strings");
======== ================== ===============================
Format Argument Type Argument Contents
======== ================== ===============================
%s const char \* UTF-8 string
%S const char \* UTF-8 string (alias for '%ls')
%ls const wchar_t \* Wide character UNICODE string
%hs const char * locale-based string
======== ================== ===============================
.. admonition:: "Long", not "locale"
The "*l*" in "%ls" is for "*long*", following the convention of "%ld".
It is not "*locale*", a common mis-mnemonic. "%S" is equivalent to
"%ls".
For example, the following function is passed a locale-base name, a
hat size, and a time value. The hat size is formatted in a UTF-8
(ASCII) string, and the time value is formatted into a wchar_t
string::
void print_order (const char *name, int size,
struct tm *timep) {
char buf[32];
const char *size_val = "unknown";
if (size > 0)
snprintf(buf, sizeof(buf), "%d", size);
size_val = buf;
}
wchar_t when[32];
wcsftime(when, sizeof(when), L"%d%b%y", timep);
xo_emit("The hat for {:name/%hs} is {:size/%s}.\n",
name, size_val);
xo_emit("It was ordered on {:order-time/%ls}.\n",
when);
}
It is important to note that xo_emit will perform the conversion
required to make appropriate output. Text style output uses the
current locale (as described above), while XML, JSON, and HTML use
UTF-8.
UTF-8 and locale-encoded strings can use multiple bytes to encode one
column of data. The traditional "precision'" (aka "max-width") value
for "%s" printf formatting becomes overloaded since it specifies both
the number of bytes that can be safely referenced and the maximum
number of columns to emit. xo_emit uses the precision as the former,
and adds a third value for specifying the maximum number of columns.
In this example, the name field is printed with a minimum of 3 columns
and a maximum of 6. Up to ten bytes of data at the location given by
'name' are in used in filling those columns::
xo_emit("{:name/%3.10.6s}", name);
Characters Outside of Field Definitions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Characters in the format string that are not part of a field
definition are copied to the output for the TEXT style, and are
ignored for the JSON and XML styles. For HTML, these characters are
placed in a <div> with class "text"::
EXAMPLE:
xo_emit("The hat is {:size/%s}.\n", size_val);
TEXT:
The hat is extra small.
XML:
<size>extra small</size>
JSON:
"size": "extra small"
HTML:
<div class="text">The hat is </div>
<div class="data" data-tag="size">extra small</div>
<div class="text">.</div>
.. index:: errno
"%m" Is Supported
~~~~~~~~~~~~~~~~~
libxo supports the '%m' directive, which formats the error message
associated with the current value of "errno". It is the equivalent
of "%s" with the argument strerror(errno)::
xo_emit("{:filename} cannot be opened: {:error/%m}", filename);
xo_emit("{:filename} cannot be opened: {:error/%s}",
filename, strerror(errno));
"%n" Is Not Supported
~~~~~~~~~~~~~~~~~~~~~
libxo does not support the '%n' directive. It's a bad idea and we
just don't do it.
The Encoding Format (eformat)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The "eformat" string is the format string used when encoding the field
for JSON and XML. If not provided, it defaults to the primary format
with any minimum width removed. If the primary is not given, both
default to "%s".
Content Strings
~~~~~~~~~~~~~~~
For padding and labels, the content string is considered the content,
unless a format is given.
.. index:: printf-like
Argument Validation
~~~~~~~~~~~~~~~~~~~
Many compilers and tool chains support validation of printf-like
arguments. When the format string fails to match the argument list,
a warning is generated. This is a valuable feature and while the
formatting strings for libxo differ considerably from printf, many of
these checks can still provide build-time protection against bugs.
libxo provide variants of functions that provide this ability, if the
"--enable-printflike" option is passed to the "configure" script.
These functions use the "_p" suffix, like "xo_emit_p()",
xo_emit_hp()", etc.
The following are features of libxo formatting strings that are
incompatible with printf-like testing:
- implicit formats, where "{:tag}" has an implicit "%s";
- the "max" parameter for strings, where "{:tag/%4.10.6s}" means up to
ten bytes of data can be inspected to fill a minimum of 4 columns and
a maximum of 6;
- percent signs in strings, where "{:filled}%" makes a single,
trailing percent sign;
- the "l" and "h" modifiers for strings, where "{:tag/%hs}" means
locale-based string and "{:tag/%ls}" means a wide character string;
- distinct encoding formats, where "{:tag/#%s/%s}" means the display
styles (text and HTML) will use "#%s" where other styles use "%s";
If none of these features are in use by your code, then using the "_p"
variants might be wise:
================== ========================
Function printf-like Equivalent

xo_emit_hv xo_emit_hvp
xo_emit_h xo_emit_hp
xo_emit xo_emit_p
xo_emit_warn_hcv xo_emit_warn_hcvp

.. index:: performance
.. index:: XOEF_RETAIN
.. _retain:
Retaining Parsed Format Information
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
libxo can retain the parsed internal information related to the given
format string, allowing subsequent xo_emit calls, the retained
information is used, avoiding repetitive parsing of the format string::
SYNTAX:
int xo_emit_f(xo_emit_flags_t flags, const char fmt, ...);
EXAMPLE:
xo_emit_f(XOEF_RETAIN, "{:some/%02d}{:thing/%-6s}{:fancy}\n",
some, thing, fancy);
To retain parsed format information, use the XOEF_RETAIN flag to the
xo_emit_f() function. A complete set of xo_emit_f functions exist to
match all the xo_emit function signatures (with handles, varadic
argument, and printf-like flags):
================== ========================
Function Flags Equivalent
================== ========================
xo_emit_hv xo_emit_hvf
xo_emit_h xo_emit_hf
xo_emit xo_emit_f
xo_emit_hvp xo_emit_hvfp
xo_emit_hp xo_emit_hfp
xo_emit_p xo_emit_fp
================== ========================
The format string must be immutable across multiple calls to xo_emit_f(),
since the library retains the string. Typically this is done by using
static constant strings, such as string literals. If the string is not
immutable, the XOEF_RETAIN flag must not be used.
The functions xo_retain_clear() and xo_retain_clear_all() release
internal information on either a single format string or all format
strings, respectively. Neither is required, but the library will
retain this information until it is cleared or the process exits::
const char *fmt = "{:name} {:count/%d}\n";
for (i = 0; i < 1000; i++) {
xo_open_instance("item");
xo_emit_f(XOEF_RETAIN, fmt, name[i], count[i]);
}
xo_retain_clear(fmt);
The retained information is kept as thread-specific data.
Example
~~~~~~~
In this example, the value for the number of items in stock is emitted::
xo_emit("{P: }{Lwc:In stock}{:in-stock/%u}\n",
instock);
This call will generate the following output::
TEXT:
In stock: 144
XML:
<in-stock>144</in-stock>
JSON:
"in-stock": 144,
HTML:
<div class="line">
<div class="padding"> </div>
<div class="label">In stock</div>
<div class="decoration">:</div>
<div class="padding"> </div>
<div class="data" data-tag="in-stock">144</div>
</div>
Clearly HTML wins the verbosity award, and this output does
not include XOF_XPATH or XOF_INFO data, which would expand the
penultimate line to::
<div class="data" data-tag="in-stock"
data-xpath="/top/data/item/in-stock"
data-type="number"
data-help="Number of items in stock">144</div>

Field Modifiers
~~~~~~~~~~~~~~~
Field modifiers are flags which modify the way content emitted for
particular output styles:
=== =============== ===================================================
M Name Description
=== =============== ===================================================
a argument The content appears as a 'const char \*' argument
c colon A colon (":") is appended after the label
d display Only emit field for display styles (text/HTML)
e encoding Only emit for encoding styles (XML/JSON)
g gettext Call gettext on field's render content
h humanize (hn) Format large numbers in human-readable style
\ hn-space Humanize: Place space between numeric and unit
\ hn-decimal Humanize: Add a decimal digit, if number < 10
\ hn-1000 Humanize: Use 1000 as divisor instead of 1024
k key Field is a key, suitable for XPath predicates
l leaf-list Field is a leaf-list
n no-quotes Do not quote the field when using JSON style
p plural Gettext: Use comma-separated plural form
q quotes Quote the field when using JSON style
t trim Trim leading and trailing whitespace
w white A blank (" ") is appended after the label
=== =============== ===================================================
Roles and modifiers can also use more verbose names, when preceded by
a comma. For example, the modifier string "Lwc" (or "L,white,colon")
means the field has a label role (text that describes the next field)
and should be followed by a colon ('c') and a space ('w'). The
modifier string "Vkq" (or ":key,quote") means the field has a value
role (the default role), that it is a key for the current instance,
and that the value should be quoted when encoded for JSON.
.. index:: Field Modifiers; Argument
.. _argument-modifier:
The Argument Modifier ({a:})
++++++++++++++++++++++++++++
.. index:: Field Modifiers; Argument
The argument modifier indicates that the content of the field
descriptor will be placed as a UTF-8 string (const char \*) argument
within the xo_emit parameters::
EXAMPLE:
xo_emit("{La:} {a:}\n", "Label text", "label", "value");
TEXT:
Label text value
JSON:
"label": "value"
XML:
<label>value</label>
The argument modifier allows field names for value fields to be passed
on the stack, avoiding the need to build a field descriptor using
snprintf. For many field roles, the argument modifier is not needed,
since those roles have specific mechanisms for arguments, such as
"{C:fg-%s}".
.. index:: Field Modifiers; Colon
.. _colon-modifier:
The Colon Modifier ({c:})

.. index:: Field Modifiers; Colon
The colon modifier appends a single colon to the data value::
EXAMPLE:
xo_emit("{Lc:Name}{:name}\n", "phil");
TEXT:
Name:phil
The colon modifier is only used for the TEXT and HTML output
styles. It is commonly combined with the space modifier ('{w:}').
It is purely a convenience feature.

EXAMPLE:
xo_emit("{Lcw:Name}{d:name} {:id/%d}\n", "phil", 1);
TEXT:
Name: phil 1
XML:
<id>1</id>
The display modifier is the opposite of the encoding modifier, and
they are often used to give to distinct views of the underlying data.

.. index:: Field Modifiers; Gettext
.. _gettext-modifier:
The Gettext Modifier ({g:})
+++++++++++++++++++++++++++
.. index:: Field Modifiers; Gettext
.. index:: gettext
The gettext modifier is used to translate individual fields using the
gettext domain (typically set using the "`{G:}`" role) and current
language settings. Once libxo renders the field value, it is passed
to gettext(3), where it is used as a key to find the native language
translation.
In the following example, the strings "State" and "full" are passed
to gettext() to find locale-based translated strings::
xo_emit("{Lgwc:State}{g:state}\n", "full");
See :ref:`gettext-role`, :ref:`plural-modifier`, and
:ref:`i18n` for additional details.
.. index:: Field Modifiers; Humanize
.. _humanize-modifier:
The Humanize Modifier ({h:})
++++++++++++++++++++++++++++
.. index:: Field Modifiers; Humanize
The humanize modifier is used to render large numbers as in a
human-readable format. While numbers like "44470272" are completely
readable to computers and savants, humans will generally find "44M"
more meaningful.
"hn" can be used as an alias for "humanize".
The humanize modifier only affects display styles (TEXT and HMTL).
The "`no-humanize`" option (See :ref:`options`) will block
the function of the humanize modifier.
There are a number of modifiers that affect details of humanization.
These are only available in as full names, not single characters. The
"`hn-space`" modifier places a space between the number and any
multiplier symbol, such as "M" or "K" (ex: "44 K"). The
"`hn-decimal`" modifier will add a decimal point and a single tenths
digit when the number is less than 10 (ex: "4.4K"). The "`hn-1000`"
modifier will use 1000 as divisor instead of 1024, following the
JEDEC-standard instead of the more natural binary powers-of-two
tradition::
EXAMPLE:
xo_emit("{h:input/%u}, {h,hn-space:output/%u}, "
"{h,hn-decimal:errors/%u}, {h,hn-1000:capacity/%u}, "
"{h,hn-decimal:remaining/%u}\n",
input, output, errors, capacity, remaining);
TEXT:
21, 57 K, 96M, 44M, 1.2G
In the HTML style, the original numeric value is rendered in the
"data-number" attribute on the <div> element::
<div class="data" data-tag="errors"
data-number="100663296">96M</div>
.. index:: Field Modifiers; Key
.. _key-modifier:
The Key Modifier ({k:})
+++++++++++++++++++++++
.. index:: Field Modifiers; Key
The key modifier is used to indicate that a particular field helps
uniquely identify an instance of list data::
EXAMPLE:
xo_open_list("user");
for (i = 0; i < num_users; i++) {
xo_open_instance("user");
xo_emit("User {k:name} has {:count} tickets\n",
user[i].u_name, user[i].u_tickets);
xo_close_instance("user");
}
xo_close_list("user");
.. index:: XOF_XPATH
Currently the key modifier is only used when generating XPath value
for the HTML output style when XOF_XPATH is set, but other uses are
likely in the near future.
.. index:: Field Modifiers; Leaf-List
.. _leaf-list:
The Leaf-List Modifier ({l:})
+++++++++++++++++++++++++++++
.. index:: Field Modifiers; Leaf-List
The leaf-list modifier is used to distinguish lists where each
instance consists of only a single value. In XML, these are
rendered as single elements, where JSON renders them as arrays::
EXAMPLE:
for (i = 0; i < num_users; i++) {
xo_emit("Member {l:user}\n", user[i].u_name);
}
XML:
<user>phil</user>
<user>pallavi</user>
JSON:
"user": [ "phil", "pallavi" ]
The name of the field must match the name of the leaf list.
.. index:: Field Modifiers; No-Quotes
.. _no-quotes-modifier:
The No-Quotes Modifier ({n:})
+++++++++++++++++++++++++++++
.. index:: Field Modifiers; No-Quotes
The no-quotes modifier (and its twin, the 'quotes' modifier) affect
the quoting of values in the JSON output style. JSON uses quotes for
string value, but no quotes for numeric, boolean, and null data.
xo_emit applies a simple heuristic to determine whether quotes are
needed, but often this needs to be controlled by the caller::
EXAMPLE:
const char *bool = is_true ? "true" : "false";
xo_emit("{n:fancy/%s}", bool);
JSON:
"fancy": true
.. index:: Field Modifiers; Plural
.. _plural-modifier:
The Plural Modifier ({p:})
++++++++++++++++++++++++++
.. index:: Field Modifiers; Plural
.. index:: gettext
The plural modifier selects the appropriate plural form of an
expression based on the most recent number emitted and the current
language settings. The contents of the field should be the singular
and plural English values, separated by a comma::
xo_emit("{:bytes} {Ngp:byte,bytes}\n", bytes);
The plural modifier is meant to work with the gettext modifier ({g:})
but can work independently. See :ref:`gettext-modifier`.
When used without the gettext modifier or when the message does not
appear in the message catalog, the first token is chosen when the last
numeric value is equal to 1; otherwise the second value is used,
mimicking the simple pluralization rules of English.
When used with the gettext modifier, the ngettext(3) function is
called to handle the heavy lifting, using the message catalog to
convert the singular and plural forms into the native language.
.. index:: Field Modifiers; Quotes
.. _quotes-modifier:
The Quotes Modifier ({q:})
++++++++++++++++++++++++++
.. index:: Field Modifiers; Quotes
The quotes modifier (and its twin, the 'no-quotes' modifier) affect
the quoting of values in the JSON output style. JSON uses quotes for
string value, but no quotes for numeric, boolean, and null data.
xo_emit applies a simple heuristic to determine whether quotes are
needed, but often this needs to be controlled by the caller::
EXAMPLE:
xo_emit("{q:time/%d}", 2014);
JSON:
"year": "2014"
The heuristic is based on the format; if the format uses any of the
following conversion specifiers, then no quotes are used::
d i o u x X D O U e E f F g G a A c C p
.. index:: Field Modifiers; Trim
.. _trim-modifier:
The Trim Modifier ({t:})
++++++++++++++++++++++++
.. index:: Field Modifiers; Trim
The trim modifier removes any leading or trailing whitespace from
the value::
EXAMPLE:
xo_emit("{t:description}", " some input ");
JSON:
"description": "some input"
.. index:: Field Modifiers; White Space
.. _white-space-modifier:
The White Space Modifier ({w:})
+++++++++++++++++++++++++++++++
.. index:: Field Modifiers; White Space
The white space modifier appends a single space to the data value::
EXAMPLE:
xo_emit("{Lw:Name}{:name}\n", "phil");
TEXT:
Name phil
The white space modifier is only used for the TEXT and HTML output
styles. It is commonly combined with the colon modifier ('{c:}').
It is purely a convenience feature.
Note that the sense of the 'w' modifier is reversed for the units role
({Uw:}); a blank is added before the contents, rather than after it.

.. index:: Field Roles
.. _field-roles:
Field Roles
~~~~~~~~~~~
Field roles are optional, and indicate the role and formatting of the
content. The roles are listed below; only one role is permitted:
=== ============== =================================================
R Name Description
=== ============== =================================================
C color Field has color and effect controls
D decoration Field is non-text (e.g., colon, comma)
E error Field is an error message
G gettext Call gettext(3) on the format string
L label Field is text that prefixes a value
N note Field is text that follows a value
P padding Field is spaces needed for vertical alignment
T title Field is a title value for headings
U units Field is the units for the previous value field
V value Field is the name of field (the default)
W warning Field is a warning message
[ start-anchor Begin a section of anchored variable-width text
] stop-anchor End a section of anchored variable-width text
=== ============== =================================================
::
EXAMPLE:
xo_emit("{L:Free}{D::}{P: }{:free/%u} {U:Blocks}\n",
free_blocks);
When a role is not provided, the "*value*" role is used as the default.
Roles and modifiers can also use more verbose names, when preceded by
a comma::
EXAMPLE:
xo_emit("{,label:Free}{,decoration::}{,padding: }"
"{,value:free/%u} {,units:Blocks}\n",
free_blocks);
.. index:: Field Roles; Color
.. _color-role:
The Color Role ({C:})
+++++++++++++++++++++
Colors and effects control how text values are displayed; they are
used for display styles (TEXT and HTML)::
xo_emit("{C:bold}{:value}{C:no-bold}\n", value);
Colors and effects remain in effect until modified by other "C"-role
fields::
xo_emit("{C:bold}{C:inverse}both{C:no-bold}only inverse\n");
If the content is empty, the "*reset*" action is performed::
xo_emit("{C:both,underline}{:value}{C:}\n", value);
The content should be a comma-separated list of zero or more colors or
display effects::
xo_emit("{C:bold,inverse}Ugly{C:no-bold,no-inverse}\n");
The color content can be either static, when placed directly within
the field descriptor, or a printf-style format descriptor can be used,
if preceded by a slash ("/"):
xo_emit("{C:/%s%s}{:value}{C:}", need_bold ? "bold" : "",
need_underline ? "underline" : "", value);
Color names are prefixed with either "fg-" or "bg-" to change the
foreground and background colors, respectively::
xo_emit("{C:/fg-%s,bg-%s}{Lwc:Cost}{:cost/%u}{C:reset}\n",
fg_color, bg_color, cost);
The following table lists the supported effects:
=============== =================================================
Name Description
=============== =================================================
bg-XXXXX Change background color
bold Start bold text effect
fg-XXXXX Change foreground color
inverse Start inverse (aka reverse) text effect
no-bold Stop bold text effect
no-inverse Stop inverse (aka reverse) text effect
no-underline Stop underline text effect
normal Reset effects (only)
reset Reset colors and effects (restore defaults)
underline Start underline text effect
=============== =================================================
The following color names are supported:
========= ============================================
Name Description
========= ============================================
black
blue
cyan
default Default color for foreground or background
green
magenta
red
white
yellow
========= ============================================
When using colors, the developer should remember that users will
change the foreground and background colors of terminal session
according to their own tastes, so assuming that "blue" looks nice is
never safe, and is a constant annoyance to your dear author. In
addition, a significant percentage of users (1 in 12) will be color
blind. Depending on color to convey critical information is not a
good idea. Color should enhance output, but should not be used as the
sole means of encoding information.
.. index:: Field Roles; Decoration
.. _decoration-role:
The Decoration Role ({D:})
++++++++++++++++++++++++++
Decorations are typically punctuation marks such as colons,
semi-colons, and commas used to decorate the text and make it simpler
for human readers. By marking these distinctly, HTML usage scenarios
can use CSS to direct their display parameters::
xo_emit("{D:((}{:name}{D:))}\n", name);
.. index:: Field Roles; Gettext
.. _gettext-role:
The Gettext Role ({G:})
+++++++++++++++++++++++
libxo supports internationalization (i18n) through its use of
gettext(3). Use the "{G:}" role to request that the remaining part of
the format string, following the "{G:}" field, be handled using
gettext().
Since gettext() uses the string as the key into the message catalog,
libxo uses a simplified version of the format string that removes
unimportant field formatting and modifiers, stopping minor formatting
changes from impacting the expensive translation process. A developer
change such as changing "/%06d" to "/%08d" should not force hand
inspection of all .po files.
The simplified version can be generated for a single message using the
"`xopo -s $text`" command, or an entire .pot can be translated using
the "`xopo -f $input -o $output`" command.
xo_emit("{G:}Invalid token\n");
The {G:} role allows a domain name to be set. gettext calls will
continue to use that domain name until the current format string
processing is complete, enabling a library function to emit strings
using it's own catalog. The domain name can be either static as the
content of the field, or a format can be used to get the domain name
from the arguments.
xo_emit("{G:libc}Service unavailable in restricted mode\n");
See :ref:`i18n` for additional details.
.. index:: Field Roles; Label
.. _label-role:
The Label Role ({L:})
+++++++++++++++++++++
Labels are text that appears before a value::
xo_emit("{Lwc:Cost}{:cost/%u}\n", cost);
If a label needs to include a slash, it must be escaped using two
backslashes, one for the C compiler and one for libxo::
xo_emit("{Lc:Low\\/warn level}{:level/%s}\n", level);
.. index:: Field Roles; Note
.. _note-role:
The Note Role ({N:})
++++++++++++++++++++
Notes are text that appears after a value::
xo_emit("{:cost/%u} {N:per year}\n", cost);
.. index:: Field Roles; Padding
.. _padding-role:
The Padding Role ({P:})
+++++++++++++++++++++++
Padding represents whitespace used before and between fields.
The padding content can be either static, when placed directly within
the field descriptor, or a printf-style format descriptor can be used,
if preceded by a slash ("/")::
xo_emit("{P: }{Lwc:Cost}{:cost/%u}\n", cost);
xo_emit("{P:/%30s}{Lwc:Cost}{:cost/%u}\n", "", cost);
.. index:: Field Roles; Title
.. _title-role:
The Title Role ({T:})
+++++++++++++++++++++
Title are heading or column headers that are meant to be displayed to
the user. The title can be either static, when placed directly within
the field descriptor, or a printf-style format descriptor can be used,
if preceded by a slash ("/")::
xo_emit("{T:Interface Statistics}\n");
xo_emit("{T:/%20.20s}{T:/%6.6s}\n", "Item Name", "Cost");
Title fields have an extra convenience feature; if both content and
format are specified, instead of looking to the argument list for a
value, the content is used, allowing a mixture of format and content
within the field descriptor::
xo_emit("{T:Name/%20s}{T:Count/%6s}\n");
Since the incoming argument is a string, the format must be "%s" or
something suitable.
.. index:: Field Roles; Units
.. index:: XOF_UNITS
.. _units-role:
The Units Role ({U:})
+++++++++++++++++++++
Units are the dimension by which values are measured, such as degrees,
miles, bytes, and decibels. The units field carries this information
for the previous value field::
xo_emit("{Lwc:Distance}{:distance/%u}{Uw:miles}\n", miles);
Note that the sense of the 'w' modifier is reversed for units;
a blank is added before the contents, rather than after it.
When the XOF_UNITS flag is set, units are rendered in XML as the
"units" attribute::
<distance units="miles">50</distance>
Units can also be rendered in HTML as the "data-units" attribute::
<div class="data" data-tag="distance" data-units="miles"
data-xpath="/top/data/distance">50</div>
.. index:: Field Roles; Value
.. _value-role:
The Value Role ({V:} and {:})
+++++++++++++++++++++++++++++
The value role is used to represent the a data value that is
interesting for the non-display output styles (XML and JSON). Value
is the default role; if no other role designation is given, the field
is a value. The field name must appear within the field descriptor,
followed by one or two format descriptors. The first format
descriptor is used for display styles (TEXT and HTML), while the
second one is used for encoding styles (XML and JSON). If no second
format is given, the encoding format defaults to the first format,
with any minimum width removed. If no first format is given, both
format descriptors default to "%s"::
xo_emit("{:length/%02u}x{:width/%02u}x{:height/%02u}\n",
length, width, height);
xo_emit("{:author} wrote \"{:poem}\" in {:year/%4d}\n,
author, poem, year);
.. index:: Field Roles; Anchor
.. _anchor-role:
The Anchor Roles ({[:} and {]:})
++++++++++++++++++++++++++++++++
The anchor roles allow a set of strings by be padded as a group,
but still be visible to xo_emit as distinct fields. Either the start
or stop anchor can give a field width and it can be either directly in
the descriptor or passed as an argument. Any fields between the start
and stop anchor are padded to meet the minimum width given.
To give a width directly, encode it as the content of the anchor tag::
xo_emit("({[:10}{:min/%d}/{:max/%d}{]:})\n", min, max);
To pass a width as an argument, use "%d" as the format, which must
appear after the "/". Note that only "%d" is supported for widths.
Using any other value could ruin your day::
xo_emit("({[:/%d}{:min/%d}/{:max/%d}{]:})\n", width, min, max);
If the width is negative, padding will be added on the right, suitable
for left justification. Otherwise the padding will be added to the
left of the fields between the start and stop anchors, suitable for
right justification. If the width is zero, nothing happens. If the
number of columns of output between the start and stop anchors is less
than the absolute value of the given width, nothing happens.
.. index:: XOF_WARN
Widths over 8k are considered probable errors and not supported. If
XOF_WARN is set, a warning will be generated.

.. index:: Format Strings
.. _format-strings:
Format Strings
--------------
libxo uses format strings to control the rendering of data into the
various output styles. Each format string contains a set of zero or
more field descriptions, which describe independent data fields. Each
field description contains a set of modifiers, a content string, and
zero, one, or two format descriptors. The modifiers tell libxo what
the field is and how to treat it, while the format descriptors are
formatting instructions using printf-style format strings, telling
libxo how to format the field. The field description is placed inside
a set of braces, with a colon (":") after the modifiers and a slash
("/") before each format descriptors. Text may be intermixed with
field descriptions within the format string.
The field description is given as follows::
'{' [ role | modifier ]* [',' long-names ]* ':' [ content ]
[ '/' field-format [ '/' encoding-format ]] '}'
The role describes the function of the field, while the modifiers
enable optional behaviors. The contents, field-format, and
encoding-format are used in varying ways, based on the role. These
are described in the following sections.
In the following example, three field descriptors appear. The first
is a padding field containing three spaces of padding, the second is a
label ("In stock"), and the third is a value field ("in-stock"). The
in-stock field has a "%u" format that will parse the next argument
passed to the xo_emit function as an unsigned integer::
xo_emit("{P: }{Lwc:In stock}{:in-stock/%u}\n", 65);
This single line of code can generate text (" In stock: 65\n"), XML
("<in-stock>65</in-stock>"), JSON ('"in-stock": 6'), or HTML (too
lengthy to be listed here).
While roles and modifiers typically use single character for brevity,
there are alternative names for each which allow more verbose
formatting strings. These names must be preceded by a comma, and may
follow any single-character values::
xo_emit("{L,white,colon:In stock}{,key:in-stock/%u}\n", 65);

Formatting with libxo
=====================
Most unix commands emit text output aimed at humans. It is designed
to be parsed and understood by a user. Humans are gifted at
extracting details and pattern matching in such output. Often
programmers need to extract information from this human-oriented
output. Programmers use tools like grep, awk, and regular expressions
to ferret out the pieces of information they need. Such solutions are
fragile and require maintenance when output contents change or evolve,
along with testing and validation.
Modern tool developers favor encoding schemes like XML and JSON,
which allow trivial parsing and extraction of data. Such formats are
simple, well understood, hierarchical, easily parsed, and often
integrate easier with common tools and environments. Changes to
content can be done in ways that do not break existing users of the
data, which can reduce maintenance costs and increase feature velocity.
In addition, modern reality means that more output ends up in web
browsers than in terminals, making HTML output valuable.
libxo allows a single set of function calls in source code to generate
traditional text output, as well as XML and JSON formatted data. HTML
can also be generated; "<div>" elements surround the traditional text
output, with attributes that detail how to render the data.
A single libxo function call in source code is all that's required::
xo_emit("Connecting to {:host}.{:domain}...\n", host, domain);
TEXT:
Connecting to my-box.example.com...
XML:
<host>my-box</host>
<domain>example.com</domain>
JSON:
"host": "my-box",
"domain": "example.com"
HTML:
<div class="line">
<div class="text">Connecting to </div>
<div class="data" data-tag="host"
data-xpath="/top/host">my-box</div>
<div class="text">.</div>
<div class="data" data-tag="domain"
data-xpath="/top/domain">example.com</div>
<div class="text">...</div>
</div>
Encoding Styles
---------------
There are four encoding styles supported by libxo:
- TEXT output can be display on a terminal session, allowing
compatibility with traditional command line usage.
- XML output is suitable for tools like XPath and protocols like
NETCONF.
- JSON output can be used for RESTful APIs and integration with
languages like Javascript and Python.
- HTML can be matched with a small CSS file to permit rendering in any
HTML5 browser.
In general, XML and JSON are suitable for encoding data, while TEXT is
suited for terminal output and HTML is suited for display in a web
browser (see :ref:`xohtml`).
Text Output
~~~~~~~~~~~
Most traditional programs generate text output on standard output,
with contents like::
36 ./src
40 ./bin
90 .
In this example (taken from *du* source code), the code to generate this
data might look like::
printf("%d\t%s\n", num_blocks, path);
Simple, direct, obvious. But it's only making text output. Imagine
using a single code path to make TEXT, XML, JSON or HTML, deciding at
run time which to generate.
libxo expands on the idea of printf format strings to make a single
format containing instructions for creating multiple output styles::
xo_emit("{:blocks/%d}\t{:path/%s}\n", num_blocks, path);
This line will generate the same text output as the earlier printf
call, but also has enough information to generate XML, JSON, and HTML.
The following sections introduce the other formats.
XML Output
~~~~~~~~~~
XML output consists of a hierarchical set of elements, each encoded
with a start tag and an end tag. The element should be named for data
value that it is encoding::
<item>
<blocks>36</blocks>
<path>./src</path>
</item>
<item>
<blocks>40</blocks>
<path>./bin</path>
</item>
<item>
<blocks>90</blocks>
<path>.</path>
</item>
`XML`_ is the W3C standard for encoding data.
.. _XML: https://w3c.org/TR/xml
JSON Output
~~~~~~~~~~~
JSON output consists of a hierarchical set of objects and lists, each
encoded with a quoted name, a colon, and a value. If the value is a
string, it must be quoted, but numbers are not quoted. Objects are
encoded using braces; lists are encoded using square brackets.
Data inside objects and lists is separated using commas::
items: [
{ "blocks": 36, "path" : "./src" },
{ "blocks": 40, "path" : "./bin" },
{ "blocks": 90, "path" : "./" }
]
HTML Output
~~~~~~~~~~~
HTML output is designed to allow the output to be rendered in a web
browser with minimal effort. Each piece of output data is rendered
inside a <div> element, with a class name related to the role of the
data. By using a small set of class attribute values, a CSS
stylesheet can render the HTML into rich text that mirrors the
traditional text content.
Additional attributes can be enabled to provide more details about the
data, including data type, description, and an XPath location::
<div class="line">
<div class="data" data-tag="blocks">36</div>
<div class="padding"> </div>
<div class="data" data-tag="path">./src</div>
</div>
<div class="line">
<div class="data" data-tag="blocks">40</div>
<div class="padding"> </div>
<div class="data" data-tag="path">./bin</div>
</div>
<div class="line">
<div class="data" data-tag="blocks">90</div>
<div class="padding"> </div>
<div class="data" data-tag="path">./</div>
</div>

.. index:: Getting libxo
Getting libxo
=============
libxo now ships as part of the FreeBSD Operating System (as of Release
11).
libxo source code lives on github:
https://github.com/Juniper/libxo
The latest release of libxo is available at:
https://github.com/Juniper/libxo/releases
We're using `Semantic Versioning`_ to number our releases. libxo is
open source, distributed under the BSD license. We follow the
branching scheme from `A Successful Git Branching Model`_:
we do development under the "*develop*" branch, and release from
the "*master*" branch. To clone a developer tree, run the following
command::
git clone https://github.com/Juniper/libxo.git -b develop
.. _Semantic Versioning: http://semver.org/spec/v2.0.0.html
.. _A Successful Git Branching Model:
http://nvie.com/posts/a-successful-git-branching-model
Issues, problems, and bugs should be directly to the issues page on
our github site.
Downloading libxo Source Code
-----------------------------
You can retrieve the source for libxo in two ways:
A. Use a "distfile" for a specific release. We use github to maintain
our releases. Visit the `release page`_ to see the list of
releases. To download the latest, look for the release witeh the
green "Latest release" button and the green "libxo-RELEASE.tar.gz"
button under that section.
.. _release page: https://github.com/Juniper/libxo/releases
After downloading that release's distfile, untar it as follows::
tar -zxf libxo-RELEASE.tar.gz
cd libxo-RELEASE
.. admonition:: Solaris Users
Note: for Solaris users, your "`tar`" command lacks the "-z" flag,
so you'll need to substitute "`gzip -dc $file | tar xf -`" instead
of "`tar -zxf $file`".
B. Use the current build from github. This gives you the most recent
source code, which might be less stable than a specific release. To
build libxo from the git repo::
git clone https://github.com/Juniper/libxo.git
cd libxo
.. admonition:: Be Aware
The github repository does **not** contain the files generated by
"*autoreconf*", with the notable exception of the "*m4*" directory.
Since these files (depcomp, configure, missing, install-sh, etc) are
generated files, we keep them out of the source code repository.
This means that if you download the a release distfile, these files
will be ready and you'll just need to run "configure", but if you
download the source code from svn, then you'll need to run
"*autoreconf*" by hand. This step is done for you by the "*setup.sh*"
script, described in the next section.

To build libxo, you'll need to set up the build, run the "*configure*"
script, run the "*make*" command, and run the regression tests.
The following is a summary of the commands needed. These commands are
explained in detail in the rest of this section::
sh bin/setup.sh
cd build
../configure
make
make test
sudo make install
The following sections will walk through each of these steps with
additional details and options, but the above directions should be all
that's needed.
Setting up the build
~~~~~~~~~~~~~~~~~~~~
.. admonition: Note
If you downloaded a distfile, you can skip this step.
Run the "*setup.sh*" script to set up the build. This script runs the
"*autoreconf*" command to generate the "*configure*" script and other
generated files::
sh bin/setup.sh
Note: We're are currently using autoreconf version 2.69.
Running the "configure" Script
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Configure (and autoconf in general) provides a means of building
software in diverse environments. Our configure script supports
a set of options that can be used to adjust to your operating
environment. Use "`configure --help`" to view these options.
We use the "*build*" directory to keep object files and generated files
away from the source tree.
To run the configure script, change into the "*build*" directory, and
run the "*configure*" script. Add any required options to the
"`../configure`" command line::
cd build
../configure
Expect to see the "*configure*" script generate the following error::
/usr/bin/rm: cannot remove `libtoolT': No such file or directory
This error is harmless and can be safely ignored.
By default, libxo installs architecture-independent files, including
extension library files, in the /usr/local directories. To specify an
installation prefix other than /usr/local for all installation files,
include the --prefix=prefix option and specify an alternate
location. To install just the extension library files in a different,
user-defined location, include the "*--with-extensions-dir=dir*" option
and specify the location where the extension libraries will live::
cd build
../configure [OPTION]... [VAR=VALUE]...
Running the "make" Command
++++++++++++++++++++++++++
Once the "*configure*" script is run, build the images using the
"`make`" command::
make
Running the Regression Tests
++++++++++++++++++++++++++++
libxo includes a set of regression tests that can be run to ensure
the software is working properly. These test are optional, but will
help determine if there are any issues running libxo on your
machine. To run the regression tests::
make test
Installing libxo
~~~~~~~~~~~~~~~~
Once the software is built, you'll need to install libxo using the
"`make install`" command. If you are the root user, or the owner of
the installation directory, simply issue the command::
make install
If you are not the "*root*" user and are using the "*sudo*" package, use::
sudo make install
Verify the installation by viewing the output of "`xo --version`"::
% xo --version
libxo version 0.3.5-git-develop
xo version 0.3.5-git-develop

Howtos: Focused Directions
==========================
This section provides task-oriented instructions for selected tasks.
If you have a task that needs instructions, please open a request as
an enhancement issue on github.
Howto: Report bugs
------------------
libxo uses github to track bugs or request enhancements. Please use
the following URL:
https://github.com/Juniper/libxo/issues
Howto: Install libxo
--------------------
libxo is open source, under a new BSD license. Source code is
available on github, as are recent releases. To get the most
current release, please visit:
https://github.com/Juniper/libxo/releases
After downloading and untarring the source code, building involves the
following steps::
sh bin/setup.sh
cd build
../configure
make
make test
sudo make install
libxo uses a distinct "*build*" directory to keep generated files
separated from source files.
.. index:: configure
Use "`../configure --help`" to display available configuration
options, which include the following::
--enable-warnings Turn on compiler warnings
--enable-debug Turn on debugging
--enable-text-only Turn on text-only rendering
--enable-printflike Enable use of GCC __printflike attribute
--disable-libxo-options Turn off support for LIBXO_OPTIONS
--with-gettext=PFX Specify location of gettext installation
--with-libslax-prefix=PFX Specify location of libslax config
Compiler warnings are a very good thing, but recent compiler version
have added some very pedantic checks. While every attempt is made to
keep libxo code warning-free, warnings are now optional. If you are
doing development work on libxo, it is required that you
use --enable-warnings to keep the code warning free, but most users
need not use this option.
.. index:: --enable-text-only
libxo provides the `--enable-text-only` option to reduce the
footprint of the library for smaller installations. XML, JSON, and
HTML rendering logic is removed.
.. index:: --with-gettext
The gettext library does not provide a simple means of learning its
location, but libxo will look for it in /usr and /opt/local. If
installed elsewhere, the installer will need to provide this
information using the "`--with-gettext=/dir/path`" option.
.. index:: libslax
libslax is not required by libxo; it contains the "oxtradoc" program
used to format documentation.
For additional information, see :ref:`building`.
Howto: Convert command line applications
----------------------------------------
Common question: How do I convert an existing command line application?
There are four basic steps for converting command line application to
use libxo::
- Setting up the context
- Converting printf calls
- Creating hierarchy
- Converting error functions
Setting up the context
~~~~~~~~~~~~~~~~~~~~~~
To use libxo, you'll need to include the "xo.h" header file in your
source code files::
#include <libxo/xo.h>
In your main() function, you'll need to call xo_parse_args to handling
argument parsing (:ref:`xo_parse_args`). This function removes
libxo-specific arguments the program's argv and returns either the
number of remaining arguments or -1 to indicate an error::
int
main (int argc, char **argv)
{
argc = xo_parse_args(argc, argv);
if (argc < 0)
return argc;
....
}
.. index:: atexit
.. index:: xo_finish_atexit
At the bottom of your main(), you'll need to call xo_finish() to
complete output processing for the default handle (:ref:`handles`). This
is required to flush internal information buffers. libxo provides the
xo_finish_atexit function that is suitable for use with the
:manpage:`atexit(3)` function::
atexit(xo_finish_atexit);
Converting printf Calls
~~~~~~~~~~~~~~~~~~~~~~~
The second task is inspecting code for :manpage:`printf(3)` calls and
replacing them with xo_emit() calls. The format strings are similar
in task, but libxo format strings wrap output fields in braces. The
following two calls produce identical text output::
OLD::
printf("There are %d %s events\n", count, etype);
NEW::
xo_emit("There are {:count/%d} {:event} events\n", count, etype);
"count" and "event" are used as names for JSON and XML output. The
"count" field uses the format "%d" and "event" uses the default "%s"
format. Both are "value" roles, which is the default role.
Since text outside of output fields is passed verbatim, other roles
are less important, but their proper use can help make output more
useful. The "note" and "label" roles allow HTML output to recognize
the relationship between text and the associated values, allowing
appropriate "hover" and "onclick" behavior. Using the "units" role
allows the presentation layer to perform conversions when needed. The
"warning" and "error" roles allows use of color and font to draw
attention to warnings. The "padding" role makes the use of vital
whitespace more clear (:ref:`padding-role`).
The "*title*" role indicates the headings of table and sections. This
allows HTML output to use CSS to make this relationship more obvious::
OLD::
printf("Statistics:\n");
NEW::
xo_emit("{T:Statistics}:\n");
The "*color*" roles controls foreground and background colors, as well
as effects like bold and underline (see :ref:`color-role`)::
NEW::
xo_emit("{C:bold}required{C:}\n");
Finally, the start- and stop-anchor roles allow justification and
padding over multiple fields (see :ref:`anchor-role`)::
OLD::
snprintf(buf, sizeof(buf), "(%u/%u/%u)", min, ave, max);
printf("%30s", buf);
NEW::
xo_emit("{[:30}({:minimum/%u}/{:average/%u}/{:maximum/%u}{]:}",
min, ave, max);
Creating Hierarchy
~~~~~~~~~~~~~~~~~~
Text output doesn't have any sort of hierarchy, but XML and JSON
require this. Typically applications use indentation to represent
these relationship::
OLD::
printf("table %d\n", tnum);
for (i = 0; i < tmax; i++) {
printf(" %s %d\n", table[i].name, table[i].size);
}
NEW::
xo_emit("{T:/table %d}\n", tnum);
xo_open_list("table");
for (i = 0; i < tmax; i++) {
xo_open_instance("table");
xo_emit("{P: }{k:name} {:size/%d}\n",
table[i].name, table[i].size);
xo_close_instance("table");
}
xo_close_list("table");
The open and close list functions are used before and after the list,
and the open and close instance functions are used before and after
each instance with in the list.
Typically these developer looks for a "for" loop as an indication of
where to put these calls.
In addition, the open and close container functions allow for
organization levels of hierarchy::
OLD::
printf("Paging information:\n");
printf(" Free: %lu\n", free);
printf(" Active: %lu\n", active);
printf(" Inactive: %lu\n", inactive);
NEW::
xo_open_container("paging-information");
xo_emit("{P: }{L:Free: }{:free/%lu}\n", free);
xo_emit("{P: }{L:Active: }{:active/%lu}\n", active);
xo_emit("{P: }{L:Inactive: }{:inactive/%lu}\n", inactive);
xo_close_container("paging-information");
Converting Error Functions
~~~~~~~~~~~~~~~~~~~~~~~~~~
libxo provides variants of the standard error and warning functions,
:manpage:`err(3)` and :manpage:`warn(3)`. There are two variants, one
for putting the errors on standard error, and the other writes the
errors and warnings to the handle using the appropriate encoding
style::
OLD::
err(1, "cannot open output file: %s", file);
NEW::
xo_err(1, "cannot open output file: %s", file);
xo_emit_err(1, "cannot open output file: {:filename}", file);
.. index:: xo_finish
Call xo_finish
~~~~~~~~~~~~~~
One important item: call `xo_finish` at the end of your program so
ensure that all buffered data is written out. You can call it
explicitly call it, or use :manpage:`atexit(3)` to have
`xo_finish_atexit` called implicitly on exit::
OLD::
exit(0);
NEW::
xo_finish();
exit(0);

.. _i18n:
Howto: Internationalization (i18n)
-----------------------------------------------
How do I use libxo to support internationalization?
libxo allows format and field strings to be used a keys into message
catalogs to enable translation into a user's native language by
invoking the standard :manpage:`gettext(3)` functions.
gettext setup is a bit complicated: text strings are extracted from
source files into "*portable object template*" (.pot) files using the
`xgettext` command. For each language, this template file is used as
the source for a message catalog in the "*portable object*" (.po)
format, which are translated by hand and compiled into "*machine
object*" (.mo) files using the `msgfmt` command. The .mo files are
then typically installed in the /usr/share/locale or
/opt/local/share/locale directories. At run time, the user's language
settings are used to select a .mo file which is searched for matching
messages. Text strings in the source code are used as keys to look up
the native language strings in the .mo file.
Since the xo_emit format string is used as the key into the message
catalog, libxo removes unimportant field formatting and modifiers from
the format string before use so that minor formatting changes will not
impact the expensive translation process. We don't want a developer
change such as changing "/%06d" to "/%08d" to force hand inspection of
all .po files. The simplified version can be generated for a single
message using the `xopo -s $text` command, or an entire .pot can be
translated using the `xopo -f $input -o $output` command::
EXAMPLE:
% xopo -s "There are {:count/%u} {:event/%.6s} events\n"
There are {:count} {:event} events\n
Recommended workflow:
# Extract text messages
xgettext --default-domain=foo --no-wrap \
--add-comments --keyword=xo_emit --keyword=xo_emit_h \
--keyword=xo_emit_warn -C -E -n --foreign-user \
-o foo.pot.raw foo.c
# Simplify format strings for libxo
xopo -f foo.pot.raw -o foo.pot
# For a new language, just copy the file
cp foo.pot po/LC/my_lang/foo.po
# For an existing language:
msgmerge --no-wrap po/LC/my_lang/foo.po \
foo.pot -o po/LC/my_lang/foo.po.new
# Now the hard part: translate foo.po using tools
# like poedit or emacs' po-mode
# Compile the finished file; Use of msgfmt's "-v" option is
# strongly encouraged, so that "fuzzy" entries are reported.
msgfmt -v -o po/my_lang/LC_MESSAGES/foo.mo po/my_lang/foo.po
# Install the .mo file
sudo cp po/my_lang/LC_MESSAGES/foo.mo \
/opt/local/share/locale/my_lang/LC_MESSAGE/
Once these steps are complete, you can use the `gettext` command to
test the message catalog::
gettext -d foo -e "some text"
i18n and xo_emit
~~~~~~~~~~~~~~~~
There are three features used in libxo used to support i18n:
- The "{G:}" role looks for a translation of the format string.
- The "{g:}" modifier looks for a translation of the field.
- The "{p:}" modifier looks for a pluralized version of the field.
Together these three flags allows a single function call to give
native language support, as well as libxo's normal XML, JSON, and HTML
support::
printf(gettext("Received %zu %s from {g:server} server\n"),
counter, ngettext("byte", "bytes", counter),
gettext("web"));
xo_emit("{G:}Received {:received/%zu} {Ngp:byte,bytes} "
"from {g:server} server\n", counter, "web");
libxo will see the "{G:}" role and will first simplify the format
string, removing field formats and modifiers::
"Received {:received} {N:byte,bytes} from {:server} server\n"
libxo calls :manpage:`gettext(3)` with that string to get a localized
version. If your language were *Pig Latin*, the result might look
like::
"Eceivedray {:received} {N:byte,bytes} omfray "
"{:server} erversay\n"
Note the field names do not change and they should not be translated.
The contents of the note ("byte,bytes") should also not be translated,
since the "g" modifier will need the untranslated value as the key for
the message catalog.
The field "{g:server}" requests the rendered value of the field be
translated using :manpage:`gettext(3)`. In this example, "web" would
be used.
The field "{Ngp:byte,bytes}" shows an example of plural form using the
"{p:}" modifier with the "{g:}" modifier. The base singular and plural
forms appear inside the field, separated by a comma. At run time,
libxo uses the previous field's numeric value to decide which form to
use by calling :manpage:`ngettext(3)`.
If a domain name is needed, it can be supplied as the content of the
{G:} role. Domain names remain in use throughout the format string
until cleared with another domain name::
printf(dgettext("dns", "Host %s not found: %d(%s)\n"),
name, errno, dgettext("strerror", strerror(errno)));
xo_emit("{G:dns}Host {:hostname} not found: "
"%d({G:strerror}{g:%m})\n", name, errno);

libxo - A Library for Generating Text, XML, JSON, and HTML Output
===================================================================
The libxo library allows an application to generate text, XML, JSON,
and HTML output, suitable for both command line use and for web
applications. The application decides at run time which output style
should be produced. By using libxo, a single source code path can
emit multiple styles of output using command line options to select
the style, along with optional behaviors. libxo includes support for
multiple output streams, pluralization, color, syslog,
:manpage:`humanized(3)` output, internationalization, and UTF-8. The
library aims to minimize the cost of migrating code to libxo.
libxo ships as part of FreeBSD.

Introducing libxo
=================
The libxo library allows an application to generate text, XML, JSON,
and HTML output using a common set of function calls. The application
decides at run time which output style should be produced. The
application calls a function "xo_emit" to product output that is
described in a format string. A "field descriptor" tells libxo what
the field is and what it means. Each field descriptor is placed in
braces with printf-like :ref:`format-strings`::
xo_emit(" {:lines/%7ju} {:words/%7ju} "
"{:characters/%7ju} {d:filename/%s}\n",
linect, wordct, charct, file);
Each field can have a role, with the 'value' role being the default,
and the role tells libxo how and when to render that field (see
:ref:`field-roles` for details). Modifiers change how the field is
rendered in different output styles (see :ref:`field-modifiers` for
details. Output can then be generated in various style, using the
"--libxo" option::
% wc /etc/motd
25 165 1140 /etc/motd
% wc --libxo xml,pretty,warn /etc/motd
<wc>
<file>
<lines>25</lines>
<words>165</words>
<characters>1140</characters>
<filename>/etc/motd</filename>
</file>
</wc>
% wc --libxo json,pretty,warn /etc/motd
{
"wc": {
"file": [
{
"lines": 25,
"words": 165,
"characters": 1140,
"filename": "/etc/motd"
}
]
}
}
% wc --libxo html,pretty,warn /etc/motd
<div class="line">
<div class="text"> </div>
<div class="data" data-tag="lines"> 25</div>
<div class="text"> </div>
<div class="data" data-tag="words"> 165</div>
<div class="text"> </div>
<div class="data" data-tag="characters"> 1140</div>
<div class="text"> </div>
<div class="data" data-tag="filename">/etc/motd</div>
</div>
Same code path, same format strings, same information, but it's
rendered in distinct styles based on run-time flags.
.. admonition:: Tale of Two Code Paths
You want to prepare for the future, but you need to live in the
present. You'd love a flying car, but need to get work done today.
You want to support features like XML, JSON, and HTML rendering to
allow integration with NETCONF, REST, and web browsers, but you need
to make text output for command line users.
And you don't want multiple code paths that can't help but get out
of sync::
/* None of this "if (xml) {... } else {...}" logic */
if (xml) {
/* some code to make xml */
} else {
/* other code to make text */
/* oops! forgot to add something on both clauses! */
}
/* And ifdefs are right out. */
#ifdef MAKE_XML
/* icky */
#else
/* pooh */
#endif
But you'd really, really like all the fancy features that modern
encoding formats can provide. libxo can help.

.. index:: Options
.. _options:
Command-line Arguments
======================
libxo uses command line options to trigger rendering behavior. There
are multiple conventions for passing options, all using the
"`--libxo`" option::
--libxo <options>
--libxo=<options>
--libxo:<brief-options>
The *brief-options* is a series of single letter abbrevations, where
the *options* is a comma-separated list of words. Both provide access
to identical functionality. The following invocations are all
identical in outcome::
my-app --libxo warn,pretty arg1
my-app --libxo=warn,pretty arg1
my-app --libxo:WP arg1
Programs using libxo are expecting to call the xo_parse_args function
to parse these arguments. See :ref:`xo_parse_args` for details.
Option Keywords
---------------
Options is a comma-separated list of tokens that correspond to output
styles, flags, or features:
=============== =======================================================
Token Action
=============== =======================================================
color Enable colors/effects for display styles (TEXT, HTML)
colors=xxxx Adjust color output values
dtrt Enable "Do The Right Thing" mode
flush Flush after every libxo function call
flush-line Flush after every line (line-buffered)
html Emit HTML output
indent=xx Set the indentation level
info Add info attributes (HTML)
json Emit JSON output
keys Emit the key attribute for keys (XML)
log-gettext Log (via stderr) each gettext(3) string lookup
log-syslog Log (via stderr) each syslog message (via xo_syslog)
no-humanize Ignore the {h:} modifier (TEXT, HTML)
no-locale Do not initialize the locale setting
no-retain Prevent retaining formatting information
no-top Do not emit a top set of braces (JSON)
not-first Pretend the 1st output item was not 1st (JSON)
pretty Emit pretty-printed output
retain Force retaining formatting information
text Emit TEXT output
underscores Replace XML-friendly "-"s with JSON friendly "_"s
units Add the 'units' (XML) or 'data-units (HTML) attribute
warn Emit warnings when libxo detects bad calls
warn-xml Emit warnings in XML
xml Emit XML output
xpath Add XPath expressions (HTML)
=============== =======================================================
Most of these option are simple and direct, but some require
additional details:
- "colors" is described in :ref:`color-mapping`.
- "flush-line" performs line buffering, even when the output is not
directed to a TTY device.
- "info" generates additional data for HTML, encoded in attributes
using names that state with "data-".
- "keys" adds a "key" attribute for XML output to indicate that a leaf
is an identifier for the list member.
- "no-humanize" avoids "humanizing" numeric output (see
:ref:`humanize-modifier` for details).
- "no-locale" instructs libxo to avoid translating output to the
current locale.
- "no-retain" disables the ability of libxo to internally retain
"compiled" information about formatting strings (see :ref:`retain`
for details).
- "underscores" can be used with JSON output to change XML-friendly
names with dashes into JSON-friendly name with underscores.
- "warn" allows libxo to emit warnings on stderr when application code
make incorrect calls.
- "warn-xml" causes those warnings to be placed in XML inside the
output.
Brief Options
-------------
The brief options are simple single-letter aliases to the normal
keywords, as detailed below:
======== =============================================
Option Action
======== =============================================
c Enable color/effects for TEXT/HTML
F Force line-buffered flushing
H Enable HTML output (XO_STYLE_HTML)
I Enable info output (XOF_INFO)
i<num> Indent by <number>
J Enable JSON output (XO_STYLE_JSON)
k Add keys to XPATH expressions in HTML
n Disable humanization (TEXT, HTML)
P Enable pretty-printed output (XOF_PRETTY)
T Enable text output (XO_STYLE_TEXT)
U Add units to HTML output
u Change "-"s to "_"s in element names (JSON)
W Enable warnings (XOF_WARN)
X Enable XML output (XO_STYLE_XML)
x Enable XPath data (XOF_XPATH)
======== =============================================
.. index:: Colors
.. _color-mapping:
Color Mapping
-------------
The "colors" option takes a value that is a set of mappings from the
pre-defined set of colors to new foreground and background colors.
The value is a series of "fg/bg" values, separated by a "+". Each
pair of "fg/bg" values gives the colors to which a basic color is
mapped when used as a foreground or background color. The order is
the mappings is:
- black
- red
- green
- yellow
- blue
- magenta
- cyan
- white
Pairs may be skipped, leaving them mapped as normal, as are missing
pairs or single colors.
For example consider the following xo_emit call::
xo_emit("{C:fg-red,bg-green}Merry XMas!!{C:}\n");
To turn all colored output to red-on-blue, use eight pairs of
"red/blue" mappings separated by plus signs ("+")::
--libxo colors=red/blue+red/blue+red/blue+red/blue+\
red/blue+red/blue+red/blue+red/blue
To turn the red-on-green text to magenta-on-cyan, give a "magenta"
foreground value for red (the second mapping) and a "cyan" background
to green (the third mapping)::
--libxo colors=+magenta+/cyan
Consider the common situation where blue output looks unreadable on a
terminal session with a black background. To turn both "blue"
foreground and background output to "yellow", give only the fifth
mapping, skipping the first four mappings with bare plus signs ("+")::
--libxo colors=++++yellow/yellow
Encoders
--------
In addition to the four "built-in" formats, libxo supports an
extensible mechanism for adding encoders. These are activated
using the "encoder" keyword::
--libxo encoder=cbor
The encoder can include encoder-specific options, separated by either
colons (":") or plus signs ("+"):
--libxo encoder=csv+path=filesystem+leaf=name+no-header
--libxo encoder=csv:path=filesystem:leaf=name:no-header
For brevity, the string "@" can be used in place of the string
"encoder=".
df --libxo @csv:no-header

The "xo" Utility
================
The `xo` utility allows command line access to the functionality of
the libxo library. Using `xo`, shell scripts can emit XML, JSON, and
HTML using the same commands that emit text output.
The style of output can be selected using a specific option: "-X" for
XML, "-J" for JSON, "-H" for HTML, or "-T" for TEXT, which is the
default. The "--style <style>" option can also be used. The standard
set of "--libxo" options are available (see :ref:`options`), as well
as the :ref:`LIBXO_OPTIONS <libxo-options>` environment variable.
The `xo` utility accepts a format string suitable for `xo_emit` and
a set of zero or more arguments used to supply data for that string::
xo "The {k:name} weighs {:weight/%d} pounds.\n" fish 6
TEXT:
The fish weighs 6 pounds.
XML:
<name>fish</name>
<weight>6</weight>
JSON:
"name": "fish",
"weight": 6
HTML:
<div class="line">
<div class="text">The </div>
<div class="data" data-tag="name">fish</div>
<div class="text"> weighs </div>
<div class="data" data-tag="weight">6</div>
<div class="text"> pounds.</div>
</div>
The `--wrap $path` option can be used to wrap emitted content in a
specific hierarchy. The path is a set of hierarchical names separated
by the '/' character::
xo --wrap top/a/b/c '{:tag}' value
XML:
<top>
<a>
<b>
<c>
<tag>value</tag>
</c>
</b>
</a>
</top>
JSON:
"top": {
"a": {
"b": {
"c": {
"tag": "value"
}
}
}
}
The `--open $path` and `--close $path` can be used to emit
hierarchical information without the matching close and open
tag. This allows a shell script to emit open tags, data, and
then close tags. The `--depth` option may be used to set the
depth for indentation. The `--leading-xpath` may be used to
prepend data to the XPath values used for HTML output style::
EXAMPLE:
#!/bin/sh
xo --open top/data
xo --depth 2 '{:tag}' value
xo --close top/data
XML:
<top>
<data>
<tag>value</tag>
</data>
</top>
JSON:
"top": {
"data": {
"tag": "value"
}
}
When making partial lines of output (where the format string does not
include a newline), use the `--continuation` option to let secondary
invocations know they are adding data to an existing line.
When emitting a series of objects, use the `--not-first` option to
ensure that any details from the previous object (e.g. commas in JSON)
are handled correctly.
Use the `--top-wrap` option to ensure any top-level object details are
handled correctly, e.g. wrap the entire output in a top-level set of
braces for JSON output.
::
EXAMPLE:
#!/bin/sh
xo --top-wrap --open top/data
xo --depth 2 'First {:tag} ' value1
xo --depth 2 --continuation 'and then {:tag}\n' value2
xo --top-wrap --close top/data
TEXT:
First value1 and then value2
HTML:
<div class="line">
<div class="text">First </div>
<div class="data" data-tag="tag">value1</div>
<div class="text"> </div>
<div class="text">and then </div>
<div class="data" data-tag="tag">value2</div>
</div>
XML:
<top>
<data>
<tag>value1</tag>
<tag>value2</tag>
</data>
</top>
JSON:
{
"top": {
"data": {
"tag": "value1",
"tag": "value2"
}
}
}
Lists and Instances
-------------------
A "*list*" is set of one or more instances that appear under the same
parent. The instances contain details about a specific object. One
can think of instances as objects or records. A call is needed to
open and close the list, while a distinct call is needed to open and
close each instance of the list.
Use the `--open-list` and `--open-instances` to open lists and
instances. Use the `--close-list` and `--close-instances` to close
them. Each of these options take a `name` parameter, providing the
name of the list and instance.
In the following example, a list named "machine" is created with three
instances::
opts="--json"
xo $opts --open-list machine
NF=
for name in red green blue; do
xo $opts --depth 1 $NF --open-instance machine
xo $opts --depth 2 "Machine {k:name} has {:memory}\n" $name 55
xo $opts --depth 1 --close-instance machine
NF=--not-first
done
xo $opts $NF --close-list machine
The normal `libxo` functions use a state machine to help these
transitions, but since each `xo` command is invoked independent of the
previous calls, the state must be passed in explicitly via these
command line options.
The `--instance` option can be used to treat a single `xo` invocation
as an instance with the given set of fields::
% xo --libxo:XP --instance foo 'The {:product} is {:status}\n' stereo "in route"
<foo>
<product>stereo</product>
<status>in route</status>
</foo>
Command Line Options
--------------------
::
Usage: xo [options] format [fields]
--close <path> Close tags for the given path
--close-instance <name> Close an open instance name
--close-list <name> Close an open list name
--continuation OR -C Output belongs on same line as previous output

xohtml
======
`xohtml` is a tool for turning the output of libxo-enabled commands into
html files suitable for display in modern HTML web browsers. It can
be used to test and debug HTML output, as well as to make the user
ache to escape the world of '70s terminal devices.
`xohtml` is given a command, either on the command line or via the "-c"
option. If not command is given, standard input is used. The
command's output is wrapped in HTML tags, with references to
supporting CSS and Javascript files, and written to standard output or
the file given in the "-f" option. The "-b" option can be used to
provide an alternative base path for the support files:
============== ===================================================
Option Meaning
============== ===================================================
-b <base> Base path for finding css/javascript files
-c <command> Command to execute
-f <file> Output file name
============== ===================================================
The "-c" option takes a full command with arguments, including
any libxo options needed to generate html (`--libxo=html`). This
value must be quoted if it consists of multiple tokens.

'A percent sign appearing in text is a literal'
+++++++++++++++++++++++++++++++++++++++++++++++
The message "A percent sign appearing in text is a literal" can be caused by code like:
::
xo_emit("cost: %d", cost);
This code should be replaced with code like:
::
xo_emit("{L:cost}: {:cost/%d}", cost);
This can be a bit surprising and could be a field that was not
properly converted to a libxo-style format string.
'Unknown long name for role/modifier'
+++++++++++++++++++++++++++++++++++++
The message "Unknown long name for role/modifier" can be caused by code like:
::
xo_emit("{,humanization:value}", value);
This code should be replaced with code like:
::
xo_emit("{,humanize:value}", value);
The hn-* modifiers (hn-decimal, hn-space, hn-1000)
are only valid for fields with the {h:} modifier.
'Last character before field definition is a field type'
++++++++++++++++++++++++++++++++++++++++++++++++++++++++
The message "Last character before field definition is a field type" can be caused by code like:
A common typo:
::
xo_emit("{T:Min} T{:Max}");
This code should be replaced with code like:
::
xo_emit("{T:Min} {T:Max}");
Twiddling the "{" and the field role is a common typo.
'Encoding format uses different number of arguments'
++++++++++++++++++++++++++++++++++++++++++++++++++++
The message "Encoding format uses different number of arguments" can be caused by code like:
::
xo_emit("{:name/%6.6s %%04d/%s}", name, number);
This code should be replaced with code like:
::
xo_emit("{:name/%6.6s %04d/%s-%d}", name, number);
Both format should consume the same number of arguments off the stack
'Only one field role can be used'
+++++++++++++++++++++++++++++++++
The message "Only one field role can be used" can be caused by code like:
::
xo_emit("{LT:Max}");
This code should be replaced with code like:
::
xo_emit("{T:Max}");
'Potential missing slash after C, D, N, L, or T with format'
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
The message "Potential missing slash after C, D, N, L, or T with format" can be caused by code like:
::
xo_emit("{T:%6.6s}\n", "Max");
This code should be replaced with code like:
::
xo_emit("{T:/%6.6s}\n", "Max");
The "%6.6s" will be a literal, not a field format. While
it's possibly valid, it's likely a missing "/".
'An encoding format cannot be given (roles: DNLT)'
++++++++++++++++++++++++++++++++++++++++++++++++++
The message "An encoding format cannot be given (roles: DNLT)" can be caused by code like:
::
xo_emit("{T:Max//%s}", "Max");
Fields with the C, D, N, L, and T roles are not emitted in
the 'encoding' style (JSON, XML), so an encoding format
would make no sense.
'Format cannot be given when content is present (roles: CDLN)'
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
The message "Format cannot be given when content is present (roles: CDLN)" can be caused by code like:
::
xo_emit("{N:Max/%6.6s}", "Max");
Fields with the C, D, L, or N roles can't have both
static literal content ("{L:Label}") and a
format ("{L:/%s}").
This error will also occur when the content has a backslash
in it, like "{N:Type of I/O}"; backslashes should be escaped,
like "{N:Type of I\\/O}". Note the double backslash, one for
handling 'C' strings, and one for libxo.
'Field has color without fg- or bg- (role: C)'
++++++++++++++++++++++++++++++++++++++++++++++
The message "Field has color without fg- or bg- (role: C)" can be caused by code like:
::
xo_emit("{C:green}{:foo}{C:}", x);
This code should be replaced with code like:
::
xo_emit("{C:fg-green}{:foo}{C:}", x);
Colors must be prefixed by either "fg-" or "bg-".
'Field has invalid color or effect (role: C)'
+++++++++++++++++++++++++++++++++++++++++++++
The message "Field has invalid color or effect (role: C)" can be caused by code like:
::
xo_emit("{C:fg-purple,bold}{:foo}{C:gween}", x);
This code should be replaced with code like:
::
xo_emit("{C:fg-red,bold}{:foo}{C:fg-green}", x);
The list of colors and effects are limited. The
set of colors includes default, black, red, green,
yellow, blue, magenta, cyan, and white, which must
be prefixed by either "fg-" or "bg-". Effects are
limited to bold, no-bold, underline, no-underline,
inverse, no-inverse, normal, and reset. Values must
be separated by commas.
'Field has humanize modifier but no format string'
++++++++++++++++++++++++++++++++++++++++++++++++++
The message "Field has humanize modifier but no format string" can be caused by code like:
::
xo_emit("{h:value}", value);
This code should be replaced with code like:
::
xo_emit("{h:value/%d}", value);
Humanization is only value for numbers, which are not
likely to use the default format ("%s").
'Field has hn-* modifier but not 'h' modifier'
++++++++++++++++++++++++++++++++++++++++++++++
The message "Field has hn-* modifier but not 'h' modifier" can be caused by code like:
::
xo_emit("{,hn-1000:value}", value);
This code should be replaced with code like:
::
xo_emit("{h,hn-1000:value}", value);
The hn-* modifiers (hn-decimal, hn-space, hn-1000)
are only valid for fields with the {h:} modifier.
'Value field must have a name (as content)")'
+++++++++++++++++++++++++++++++++++++++++++++
The message "Value field must have a name (as content)")" can be caused by code like:
::
xo_emit("{:/%s}", "value");
This code should be replaced with code like:
::
xo_emit("{:tag-name/%s}", "value");
The field name is used for XML and JSON encodings. These
tags names are static and must appear directly in the
field descriptor.
'Use hyphens, not underscores, for value field name'
++++++++++++++++++++++++++++++++++++++++++++++++++++
The message "Use hyphens, not underscores, for value field name" can be caused by code like:
::
xo_emit("{:no_under_scores}", "bad");
This code should be replaced with code like:
::
xo_emit("{:no-under-scores}", "bad");
Use of hyphens is traditional in XML, and the XOF_UNDERSCORES
flag can be used to generate underscores in JSON, if desired.
But the raw field name should use hyphens.
'Value field name cannot start with digit'
++++++++++++++++++++++++++++++++++++++++++
The message "Value field name cannot start with digit" can be caused by code like:
::
xo_emit("{:10-gig/}");
This code should be replaced with code like:
::
xo_emit("{:ten-gig/}");
XML element names cannot start with a digit.
'Value field name should be lower case'
+++++++++++++++++++++++++++++++++++++++
The message "Value field name should be lower case" can be caused by code like:
::
xo_emit("{:WHY-ARE-YOU-SHOUTING}", "NO REASON");
This code should be replaced with code like:
::
xo_emit("{:why-are-you-shouting}", "no reason");
Lower case is more civilized. Even TLAs should be lower case
to avoid scenarios where the differences between "XPath" and
"Xpath" drive your users crazy. Lower case rules the seas.
'Value field name should be longer than two characters'
+++++++++++++++++++++++++++++++++++++++++++++++++++++++
The message "Value field name should be longer than two characters" can be caused by code like:
::
xo_emit("{:x}", "mumble");
This code should be replaced with code like:
::
xo_emit("{:something-meaningful}", "mumble");
Field names should be descriptive, and it's hard to
be descriptive in less than two characters. Consider
your users and try to make something more useful.
Note that this error often occurs when the field type
is placed after the colon ("{:T/%20s}"), instead of before
it ("{T:/20s}").
'Value field name contains invalid character'
+++++++++++++++++++++++++++++++++++++++++++++
The message "Value field name contains invalid character" can be caused by code like:
::
xo_emit("{:cost-in-$$/%u}", 15);
This code should be replaced with code like:
::
xo_emit("{:cost-in-dollars/%u}", 15);
An invalid character is often a sign of a typo, like "{:]}"
instead of "{]:}". Field names are restricted to lower-case
characters, digits, and hyphens.
'decoration field contains invalid character'
+++++++++++++++++++++++++++++++++++++++++++++
The message "decoration field contains invalid character" can be caused by code like:
::
xo_emit("{D:not good}");
This code should be replaced with code like:
::
xo_emit("{D:((}{:good}{D:))}", "yes");
This is minor, but fields should use proper roles. Decoration
fields are meant to hold punctuation and other characters used
to decorate the content, typically to make it more readable
to human readers.
'Anchor content should be decimal width'
++++++++++++++++++++++++++++++++++++++++
The message "Anchor content should be decimal width" can be caused by code like:
::
xo_emit("{[:mumble}");
This code should be replaced with code like:
::
xo_emit("{[:32}");
Anchors need an integer value to specify the width of
the set of anchored fields. The value can be positive
(for left padding/right justification) or negative (for
right padding/left justification) and can appear in
either the start or stop anchor field descriptor.
'Anchor format should be "%d"'
++++++++++++++++++++++++++++++
The message "Anchor format should be "%d"" can be caused by code like:
::
xo_emit("{[:/%s}");
This code should be replaced with code like:
::
xo_emit("{[:/%d}");
Anchors only grok integer values, and if the value is not static,
if must be in an 'int' argument, represented by the "%d" format.
Anything else is an error.
'Anchor cannot have both format and encoding format")'
++++++++++++++++++++++++++++++++++++++++++++++++++++++
The message "Anchor cannot have both format and encoding format")" can be caused by code like:
::
xo_emit("{[:32/%d}");
This code should be replaced with code like:
::
xo_emit("{[:32}");
Anchors can have a static value or argument for the width,
but cannot have both.
'Max width only valid for strings'
++++++++++++++++++++++++++++++++++
The message "Max width only valid for strings" can be caused by code like:
::
xo_emit("{:tag/%2.4.6d}", 55);
This code should be replaced with code like:
::
xo_emit("{:tag/%2.6d}", 55);
libxo allows a true 'max width' in addition to the traditional
printf-style 'max number of bytes to use for input'. But this
is supported only for string values, since it makes no sense
for non-strings. This error may occur from a typo,
like "{:tag/%6..6d}" where only one period should be used.

======
xolint
======
`xolint` is a tool for reporting common mistakes in format strings
in source code that invokes `xo_emit`. It allows these errors
to be diagnosed at build time, rather than waiting until runtime.
`xolint` takes the one or more C files as arguments, and reports
and errors, warning, or informational messages as needed:
============ ===================================================
Option Meaning
============ ===================================================
-c Invoke 'cpp' against the input file
-C <flags> Flags that are passed to 'cpp
-d Enable debug output
-D Generate documentation for all xolint messages
-I Generate info table code
-p Print the offending lines after the message
-V Print vocabulary of all field names
-X Extract samples from xolint, suitable for testing
============ ===================================================
The output message will contain the source filename and line number, the
class of the message, the message, and, if -p is given, the
line that contains the error::
% xolint.pl -t xolint.c
xolint.c: 16: error: anchor format should be "%d"
16 xo_emit("{[:/%s}");
The "-I" option will generate a table of `xo_info_t`_ structures,
suitable for inclusion in source code.
.. _xo_info_t: :ref:`field-information`
The "-V" option does not report errors, but prints a complete list of
all field names, sorted alphabetically. The output can help spot
inconsistencies and spelling errors.

xopo
====
The `xopo` utility filters ".pot" files generated by the
:manpage:`xgettext(1)` utility to remove formatting information
suitable for use with the "{G:}" modifier. This means that when the
developer changes the formatting portion of the field definitions, or
the fields modifiers, the string passed to :manpage:`gettext(3)` is
unchanged, avoiding the expense of updating any existing translation
files (".po" files).
The syntax for the xopo command is one of two forms; it can be used as
a filter for processing a .po or .pot file, rewriting the "*msgid*"
strings with a simplified message string. In this mode, the input is
either standard input or a file given by the "-f" option, and the
output is either standard output or a file given by the "-o" option.
In the second mode, a simple message given using the "-s" option on
the command, and the simplified version of that message is printed on
stdout:
=========== =================================
Option Meaning
=========== =================================
-o <file> Output file name
-f <file> Use the given .po file as input
-s <text> Simplify a format string
=========== =================================
::
EXAMPLE:
% xopo -s "There are {:count/%u} {:event/%.6s} events\n"
There are {:count} {:event} events\n
% xgettext --default-domain=foo --no-wrap \
--add-comments --keyword=xo_emit --keyword=xo_emit_h \
--keyword=xo_emit_warn -C -E -n --foreign-user \
-o foo.pot.raw foo.c
% xopo -f foo.pot.raw -o foo.pot
Use of the `--no-wrap` option for `xgettext` is required to
ensure that incoming msgid strings are not wrapped across multiple
lines.

.Sh Retaining Formatting Information for Constant Strings
.Pp
The
.Nm libxo
library can cache the compiled internal version of the format for
circumstances when the format will be used repeatedly, such as a loop.
This cannot be used when the format string is in a dynamic buffer,
since the cache retains a reference to the static format string,
typically a static compile-time constant value.
.Pp
Typically static strings are placed in an executable's ".text" segment,
so
.Nm libxo
knows that the formatting information in such static strings can be
cached (retained), but shared libraries will have their own ".text"
segment, so without the XOEF_RETAIN flag,
.Nm libxo
cannot presume to retain formatting information.
If a caller in shared library code want their formats retained, they
need to pass the XOEF_RETAIN flag.
.Pp
The
.Fn xo_emitr
function is a convenience function that passes the XOEF_RETAIN
flag to
.Fn xo_emit_hvf ,
and can be used in shared libraries when the format string is static.

.Sh DESCRIPTION
These functions allow callers to pass a set of flags to
.Nm
emitting functions. These processing of arguments, except for
.Fa flags ,
is identical to the base functions.
See
.Xr xo_emit 3
for additional information.
.Pp
The only currently defined flag is
.Dv XOEF_RETAIN .
.Nm
can retain the parsed internal information related to the given
format string, allowing subsequent
.Xr xo_emit 3
calls, the retained
information is used, avoiding repetitive parsing of the format string.
To retain parsed format information, use the
.Dv XOEF_RETAIN
flag to the
.Fn xo_emit_f
function.
.Pp
The format string must be immutable across multiple calls to
.Xn xo_emit_f ,
since the library retains the string.
Typically this is done by using
static constant strings, such as string literals. If the string is not
immutable, the
.Dv XOEF_RETAIN
flag must not be used.
.Pp
The functions
.Fn xo_retain_clear
and
.Fn xo_retain_clear_all
release internal information on either a single format string or all
format strings, respectively.
Neither is required, but the library will
retain this information until it is cleared or the process exits.
.Pp
The retained information is kept as thread-specific data.
.Pp
Use
.Fn xo_retain_clear
and
.Fn xo_retain_clear_all
to clear the retained information, clearing the retained information
for either a specific format string or all format strings, respectively.
These functions are only needed when the calling application wants to
clear this information; they are not generally needed.
.Sh EXAMPLES
.Pp
.Bd -literal -offset indent
for (i = 0; i < 1000; i++) {
xo_open_instance("item");
xo_emit_f(XOEF_RETAIN, "{:name} {:count/%d}\\n",
name[i], count[i]);
}
.Ed
.Pp
In this example, the caller desires to clear the retained information.
.Bd -literal -offset indent
const char *fmt = "{:name} {:count/%d}\\n";
for (i = 0; i < 1000; i++) {
xo_open_instance("item");
xo_emit_f(XOEF_RETAIN, fmt, name[i], count[i]);
}
xo_retain_clear(fmt);

traditional counterparts. See

.Fn xo_emit_field_hv "xo_handle_t *xop" "const char *rolmod" "const char *content" "const char *fmt" "const char *efmt" "va_list vap"
.Sh DESCRIPTION
The
.Fn xo_emit_field
function emits formatted output similar to
.Xr xo_emit 3
but where
.Fn xo_emit
uses a single string argument containing the description
for multiple fields,
.Fn xo_emit_field
emits a single field using multiple arguments to contain the
field description.
.Fn xo_emit_field_h
adds an explicit handle to use instead of the default
handle, while
.Fn xo_emit_field_hv
accepts a
.Fa va_list
for additional flexibility.
.Pp
The arguments
.Fa rolmod ,
.Fa content ,
.Fa fmt ,
and
.Fa efmt
are detailed in
.Xr xo_format 5 .
Using distinct arguments allows callers to pass the field description
in pieces, rather than having to use something like
.Xr snprintf 3
to build the format string required by
.Fn xo_emit .
The arguments are each NUL-terminated strings. The
.Fa rolmod
argument contains the "role" and "modifier" portions of
the field description, the
.Fa content
argument contains the "content" portion, and the
.Fa fmt
and
.Fa efmt
contain the "field-format" and "encoding-format" portions, respectively.
.Pp
As with xo_emit, the
.Fa fmt
and
.Fa efmt
values are both optional, since the field-format string
defaults to "%s", and the encoding-format's default value is
derived from the field-format
per
.Xr xo_format 5 .
However, care must be taken to avoid using a value directly as the
format, since characters like '{', '%', and '}' will be interpreted
as formatting directives, and may cause
.Nm
to dereference arbitrary values off the stack, leading to bugs,
core files, and gnashing of teeth.
.Sh EXAMPLES
In this example, a set of four values is emitted using the following
source code:
.Bd -literal -offset indent
xo_emit_field("T", title, NULL, NULL, NULL);
xo_emit_field("Vt", "max-chaos", NULL, NULL, " very ");
xo_emit_field("V", "min-chaos", "%02d", "%d", 42);
xo_emit_field_h(NULL, ",leaf-list,quotes", "sku", "%s-%u", "%s-000-%u",
"gum", 1412);
.Ed
.Sh RETURN CODE
.Nm
returns a negative value on error. If the
.Nm XOF_COLUMNS
flag has been turned on for the specific handle using
.Xr xo_set_flags 3 ,
then the number of display columns consumed by the output will be returned.

.Sh Color Mapping
The
.Fa colors
option takes a value that is a set of mappings from the
pre-defined set of colors to new foreground and background colors.
The value is a series of "fg/bg" values, separated by a "+".
Each pair of "fg/bg" values gives the colors to which a basic color is
mapped when used as a foreground or background color.
The order is the mappings is:
.Bd -literal -offset indent
- black
- red
- green
- yellow
- blue
- magenta
- cyan
- white
.Ed
.Pp
Pairs may be skipped, leaving them mapped as normal, as are missing
pairs or single colors.
.Pp
For example consider the following xo_emit call:
.Bd -literal -offset indent
xo_emit("{C:fg-red,bg-green}Merry XMas!!{C:}\n");
.Ed
.Pp
To turn all colored output to red-on-blue, use eight pairs of
"red/blue" mappings separated by plus signs ("+"):
.Bd -literal -offset indent
--libxo colors=red/blue+red/blue+red/blue+red/blue+\
red/blue+red/blue+red/blue+red/blue
.Ed
.Pp
To turn the red-on-green text to magenta-on-cyan, give a "magenta"
foreground value for red (the second mapping) and a "cyan" background
to green (the third mapping):
.Bd -literal -offset indent
--libxo colors=+magenta+/cyan
.Ed
.Pp
Consider the common situation where blue output looks unreadable on a
terminal session with a black background.
To turn both "blue" foreground and background output to "yellow",
give only the fifth mapping, skipping the first four mappings
with bare plus signs ("+"):
.Bd -literal -offset indent
--libxo colors=++++yellow/yellow
.Ed
.Pp

.Nm libxo
supports mapping between tag names, for scenarios where the tags
need to make specific values.
For example, the "user" tag might be
needed as the "owner" tag.
.Nm libxo
can perform this one-to-one tag
replacement.
.Pp
Note that
.Nm libxo
does not perform more complex transformations;
languages such as XSLT or SLAX should be used when something more than
simple one-to-one replacement is required.
.Pp
Mapping can be specified using the
.Fa map
and
.Fa map-file options.
The
.Fa map
option accepts one or more mapping, in the format "old=new",
separated by colons:
.Bd -literal -offset indent
--libxo map:one=red,map:two=blue
.Ed
.Pp
This example would turn:
.Bd -literal -offset indent
<one>fish</one>
<two>fish</two>
.Ed
.Pp
into:
.Bd -literal -offset indent
<red>fish</red>
<blue>fish</blue>
.Ed
.Pp
In another example, the command-line options:
.Bd -literal -offset indent
--libxo map:user=owner:name=file:size=bytes:modify-time=time
.Ed
.Pp
would turn:
.Bd -literal -offset indent
<entry>
<name>xx-00000009</name>
<user>phil</user>
<size>12345</size>
<modify-time value="1644355825">1644355825</modify-time>
</entry>
.Ed
.Pp
into:
.Bd -literal -offset indent
<entry>
<file>xx-00000009</file>
<owner>phil</owner>
<bytes>12345</bytes>
<time value="1644355825">1644355825</time>
</entry>
.Ed
.Pp
The
.Fa map-file
option allows the mappings to be placed into a file,
one per line:
.Bd -literal -offset indent
--libxo map-file=foo.map
.Ed
.Pp
where "foo.map" might contain:
.Bd -literal -offset indent
# comments are supported, white space is ignored
user = owner
name=file
# blank lines are allowed
size = bytes
modify-time= time
.Ed
.Pp
This untidy example demonstrates the flexibility in the
.Nm libxo
mapping files.
.Pp
If the filename given with the
.Fa map-file
option contains no slashes ("/") and such a file does not
exist in the current working directory,
.Nm libxo
will look for the file in the "map" subdirectory of the system
"share" directory, typically /usr/share/libxo/map/.
.Sh Encoders
In addition to the four "built-in" formats,
.Nm libxo
supports an extensible mechanism for adding encoders.
These are activated using the
.Fa encoder
keyword::
.Bd -literal -offset indent
--libxo encoder=cbor
.Ed
.Pp
The encoder can include encoder-specific options, separated by either
colons (":") or plus signs ("+"):
.Bd -literal -offset indent
--libxo encoder=csv+path=filesystem+leaf=name+no-header
--libxo encoder=csv:path=filesystem:leaf=name:no-header
.Ed
.Pp
For brevity, the string "@" can be used in place of the string
"encoder=".
.Bd -literal -offset indent
df --libxo @csv:no-header
.Ed
.Pp
.Sh EXAMPLES
The following are three example invocations of
.Xr ps 1 :
