The "Artistic License"
Preamble
The intent of this document is to state the conditions under which a
Package may be copied, such that the Copyright Holder maintains some
semblance of artistic control over the development of the package,
while giving the users of the package the right to use and distribute
the Package in a more-or-less customary fashion, plus the right to make
reasonable modifications.
Definitions:
"Package" refers to the collection of files distributed by the
Copyright Holder, and derivatives of that collection of files
created through textual modification.
"Standard Version" refers to such a Package if it has not been
modified, or has been modified in accordance with the wishes
of the Copyright Holder.
"Copyright Holder" is whoever is named in the copyright or
copyrights for the package.
"You" is you, if you're thinking about copying or distributing
this Package.
"Reasonable copying fee" is whatever you can justify on the
basis of media cost, duplication charges, time of people involved,
and so on. (You will not be required to justify it to the
Copyright Holder, but only to the computing community at large
as a market that must bear the fee.)
"Freely Available" means that no fee is charged for the item
itself, though there may be fees involved in handling the item.
It also means that recipients of the item may redistribute it
under the same conditions they received it.
1. You may make and give away verbatim copies of the source form of the
Standard Version of this Package without restriction, provided that you
duplicate all of the original copyright notices and associated disclaimers.
2. You may apply bug fixes, portability fixes and other modifications
derived from the Public Domain or from the Copyright Holder. A Package
modified in such a way shall still be considered the Standard Version.
3. You may otherwise modify your copy of this Package in any way, provided
that you insert a prominent notice in each changed file stating how and
when you changed that file, and provided that you do at least ONE of the
following:
a) place your modifications in the Public Domain or otherwise make them
Freely Available, such as by posting said modifications to Usenet or
an equivalent medium, or placing the modifications on a major archive
site such as uunet.uu.net, or by allowing the Copyright Holder to include
your modifications in the Standard Version of the Package.
b) use the modified Package only within your corporation or organization.
c) rename any non-standard executables so the names do not conflict
with standard executables, which must also be provided, and provide
a separate manual page for each non-standard executable that clearly
documents how it differs from the Standard Version.
d) make other distribution arrangements with the Copyright Holder.
4. You may distribute the programs of this Package in object code or
executable form, provided that you do at least ONE of the following:
a) distribute a Standard Version of the executables and library files,
together with instructions (in the manual page or equivalent) on where
to get the Standard Version.
b) accompany the distribution with the machine-readable source of
the Package with your modifications.
c) accompany any non-standard executables with their corresponding
Standard Version executables, giving the non-standard executables
non-standard names, and clearly documenting the differences in manual
pages (or equivalent), together with instructions on where to get
the Standard Version.
d) make other distribution arrangements with the Copyright Holder.
5. You may charge a reasonable copying fee for any distribution of this
Package. You may charge any fee you choose for support of this Package.
You may not charge a fee for this Package itself. However,
you may distribute this Package in aggregate with other (possibly
commercial) programs as part of a larger (possibly commercial) software
distribution provided that you do not advertise this Package as a
product of your own.
6. The scripts and library files supplied as input to or produced as
output from the programs of this Package do not automatically fall
under the copyright of this Package, but belong to whomever generated
them, and may be sold commercially, and may be aggregated with this
Package.
7. C subroutines supplied by you and linked into this Package in order
to emulate subroutines and variables of the language defined by this
Package shall not be considered part of this Package, but are the
equivalent of input as in Paragraph 6, provided these subroutines do
not change the language in any way that would cause it to fail the
regression tests for the language.
8. The name of the Copyright Holder may not be used to endorse or promote
products derived from this software without specific prior written permission.
9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR
IMPLIED WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED

The editor 'ee' (easy editor) is intended to be a simple, easy to use
terminal-based screen oriented editor that requires no instruction to
use. Its primary use would be for people who are new to computers, or who
use computers only for things like e-mail.
ee's simplified interface is highlighted by the use of pop-up menus which
make it possible for users to carry out tasks without the need to
remember commands. An information window at the top of the screen shows
the user the operations available with control-keys.
ee allows users to use full eight-bit characters. If the host system has
the capabilities, ee can use message catalogs, which would allow users to
translate the message catalog into other languages which use eight-bit
characters. See the file ee.i18n.guide for more details.
ee relies on the virtual memory abilities of the platform it is running on
and does not have its own memory management capabilities.
I am releasing ee because I hate to see new users and non-computer types
get frustrated by vi, and would like to see more intuitive interfaces for
basic tools (both character-based and graphical) become more pervasive.
Terminal capabilities and communication speeds have evolved considerably
since the time in which vi's interface was created, allowing much more
intuitive interfaces to be used. Since character-based I/O won't be
completely replaced by graphical user interfaces for at least a few more
years, I'd like to do what I can to make using computers with less
glamorous interfaces as easy to use as possible. If terminal interfaces
are still used in ten years, I hope neophytes won't still be stuck with
only vi.
For a text editor to be easy to use requires a certain set of abilities. In
order for ee to work, a terminal must have the ability to position the cursor
on the screen, and should have arrow keys that send unique sequences
(multiple characters, the first character is an "escape", octal code
'\033'). All of this information needs to be in a database called "terminfo"
(System V implementations) or "termcap" (usually used for BSD systems). In
case the arrow keys do not transmit unique sequences, motion operations are
mapped to control keys as well, but this at least partially defeats the
purpose. The curses package is used to handle the I/O which deals with the
terminal's capabilities.
While ee is based on curses, I have included here the source code to
new_curse, a subset of curses developed for use with ee. 'curses' often
will have a defect that reduces the usefulness of the editor relying upon
it.
The file new_curse.c contains a subset of 'curses', a package for
applications to use to handle screen output. Unfortunately, curses
varies from system to system, so I developed new_curse to provide
consistent behavior across systems. It works on both SystemV and BSD
systems, and while it can sometimes be slower than other curses packages,
it will get the information on the screen painted correctly more often
than vendor supplied curses. Unless problems occur during the building
of ee, it is recommended that you use new_curse rather than the curses
supplied with your system.
If you experience problems with data being displayed improperly, check
your terminal configuration, especially if you're using a terminal
emulator, and make sure that you are using the right terminfo entry
before rummaging through code. Terminfo entries often contain
inaccuracies, or incomplete information, or may not totally match the
terminal or emulator the terminal information is being used with.
Complaints that ee isn't working quite right often end up being something
else (like the terminal emulator being used).
Both ee and new_curse were developed using K&R C (also known as "classic
C"), but it can also be compiled with ANSI C. You should be able to
build ee by simply typing "make". A make file which takes into account
the characteristics of your system will be created, and then ee will be
built. If there are problems encountered, you will be notified about
them.
ee is the result of several conflicting design goals. While I know that it
solves the problems of some users, I also have no doubt that some will decry
its lack of more features. I will settle for knowing that ee does fulfill
the needs of a minority (but still large number) of users. The goals of ee
are:
1. To be so easy to use as to require no instruction.
2. To be easy to compile and, if necessary, port to new platforms
by people with relatively little knowledge of C and UNIX.
3. To have a minimum number of files to be dealt with, for compile
and installation.
4. To have enough functionality to be useful to a large number of
people.

.SH DESCRIPTION
The command
.I ee
is a simple screen oriented text editor. It is always in text insertion
mode unless there is a prompt at the bottom of the terminal, or a
menu present (in a box in the middle of the terminal). The command
.I ree
is the same as
.I ee,
but restricted to editing the named
file (no file operations, or shell escapes are allowed).
.PP
For
.I ee
to work properly, the environment variable
.SM TERM
must be set to indicate the type of terminal being used. For
example, for an
.SM HP 700/92
terminal, the
.SM TERM
variable should be set to "70092". See your System Administrator if
you need more information.

performance on some terminals).
.TP
.B +#

.SS "Control keys"
To do anything other than insert text, the user must use the control

key, represented by a "^", pressed in conjunction with an
alphabetic key, e.g., ^a) and function keys available on the keyboard
(such as
.BR "Next Page" ", " "Prev Page" ,
arrow keys, etc.).
.PP
Since not all terminals have function keys,
.I ee
has the basic cursor movement functions assigned to control keys as
well as more intuitive keys on the keyboard when available. For
instance, to move the cursor up, the user can use the up arrow key,
or
.BR ^u .

.B return
to perform the indicated task.
.PP
To the left of each menu item is a letter, which if the corresponding

.PP
The main menu in \fIee\fR is as follows:
.RS 4
.IP "\fBleave editor\fR"
If changes have been made, the user will get a menu prompting whether or
not the changes should be saved.
.IP "\fBhelp\fR"
Displays a help screen, with all of the keyboard operations and commands.
.IP "\fBfile operations\fR"
Pops up a menu for selecting whether to read a file, write to a file, or
save the current contents of the editor, as well as send the contents of
the editor to a print command (see the section \fBInitializing ee from a

.IP "\fBredraw screen\fR"
Provides a means to repaint the screen if the screen has been corrupted.
.IP "\fBsettings\fR"
Shows the current values of the operating modes, and right margin. By

.IP "\fBsearch\fR"
.br
Pops up a menu in which the user may choose to enter a string to search

.\" paragraph formatting
.\"
.SS "Paragraph Formatting"
.PP
Paragraphs are defined for \fIee\fR by a block of text bounded by:
.sp
.RS 8
.IP \(bu
Begin or end of file.
.IP \(bu
Line with no characters, or only spaces and/or tabs.
.IP \(bu
Line starting with a period ('.') or right angle bracket ('>').
.RE
.PP
A paragraph may be formatted two ways: explicitly by choosing the
\fBformat paragraph\fR menu item, or by setting \fIee\fR to automatically
format paragraphs. The automatic mode may be set via a menu, or via the
initialization file.
.PP
There are three states for text operation in \fIee\fR: free-form, margins,
and automatic formatting.
.PP
"Free-form" is best used for things like programming. There are no
restrictions on the length of lines, and no formatting takes place.
.PP
"Margins" allows the user to type in text without having to worry about going
beyond the right margin (the right margin may be set in the \fBsettings\fR
menu, the default is for the margin to be the right edge of the
terminal). This is the mode that allows the \fBformat paragraph\fR menu
item to work.
.PP
"Automatic formatting" provides word-processor-like behavior. The user
may type in text, while \fIee\fR will make sure the entire paragraph fits
within the width of the terminal every time the user inserts a space after
typing or deleting text. Margin observation must also be enabled in order for
automatic formatting to occur.
.\"
.\" modes
.\"
.SS Modes
.PP
Although ee is a 'modeless' editor (it is in text insertion mode all the
time), there are modes in some of the things it does. These include:
.RS 4
.IP "\fBtab expansion\fR"
Tabs may be inserted as a single tab character, or replaced with spaces.
.IP "\fBcase sensitivity\fR"
The search operation can be sensitive to whether characters are upper- or
lower-case, or ignore case completely.

Lines can either be truncated at the right margin, or extend on forever.
.IP "\fBauto paragraph formatting\fR"
While typing in text, the editor can try to keep it looking reasonably well
within the width of the screen.
.IP "\fBeightbit characters\fR"
Toggles whether eight bit characters are displayed as their value in angle
brackets (e.g. "<220>") or as a character.
.IP "\fBinfo window\fR"
A window showing the keyboard operations that can be performed can be
displayed or not.
.IP "\fBemacs keys\fR"
Control keys may be given bindings similar to emacs, or not.
.IP "\f16 bit characters\fR"
Toggles whether sixteen bit characters are handled as one 16-bit quantities or
two 8-bit quantities. This works primarily with the Chinese Big 5 code set.

You may set these modes via the initialization file (see below), or with a

.SS "Spell Checking"
.PP
There are two ways to have the spelling in the text checked from \fIee\fR.
One is by the traditional \fIspell\fR(1) command, the other is with the
optional \fIispell\fR(1) command.
.PP
Using \fIspell\fR, the words that are not recognized will be placed at the top
of the file. For the \fIispell\fR option, the file is written to disk,
then \fIispell\fR run on the file, and the file read back in once
\fIispell\fR has completed making changes to the file.
.\"
.\" printing
.\"
.SS "Printing the contents of the editor"
.PP
The user may select a menu item which prints the contents of the editor.
.I ee
pipes the text in the editor to the command specified by the
initialization command
.B printcommand
(see the section
.B Initializing ee from a file
below). The default is to send the contents to "lp".
.PP
Whatever the user assigns to
.B printcommand
must take input from
standard input. See your system administrator for more details.
.\"
.\" shell operations
.\"
.SS "Shell operations"
.PP
Shell commands can be executed from within
.I ee
by selecting the
.B shell command
item in the
.B miscellaneous
menu, or by placing an exclamation mark ("!") before the command to
execute at the
.B command:
prompt. Additionally, the user may direct the contents of the edit buffer
out to a shell operation (via a pipe) by using the left angle bracket
(">"), followed by a "!" and the shell command to execute. The output of
a shell operation can also be directed into the edit buffer by using a
right angle bracket ("<") before the exclamation mark. These can even be
used together to send output to a shell operation and read back the
results into the editor. So, if the editor contained a list of words
to be sorted, they could be sorted by typing the following at the command
prompt:
.RS 4
.sp
><!sort
.sp
.RE
This would send the contents of the editor to be piped into the
.I sort
utility and the result would be placed into the edit buffer at the current
cursor location. The old information would have to be deleted by the user.
.\"
.\" initializing ee from a file
.\"
.SS "Initializing ee from a file"
.PP
Since different users have different preferences, \fIee\fR allows some
slight configurability. There are three possible locations for an
initialization file for ee: the file \fI/usr/local/lib/init.ee\fR, the
file \fI.init.ee\fR in the user's home directory, or the file \fI.init.ee\fR
in the current directory (if different from the home
directory). This allows system administrators to set some preferences for
the users on a system-wide basis (for example, the \fBprint\fR command),
and the user to customize settings for particular directories (like one
for correspondence, and a different directory for programming).
.PP
The file \fI\/usr/local/lib/init.ee\fR is read first, then
\fI$HOME/.init.ee\fR, then \fI.init.ee\fR, with the settings specified by the
most recent file read taking precedence.
.PP
The following items may be entered in the initialization file:
.RS 4
.IP \fBcase\fR
Sets searches to be case sensitive.
.IP \fBnocase\fR
Sets searches to be insensitive to case (default).
.IP \fBexpand\fR
Causes \fIee\fR to expand tabs to spaces (default).
.IP \fBnoexpand\fR
Causes \fIee\fR to insert tabs as a single character.
.IP \fBinfo\fR
A small information window is displayed at the top of the terminal
(default).
.IP \fBnoinfo\fR
Turns off the display of the information window.
.IP \fBmargins\fR
Causes \fIee\fR to truncate lines at the right margin when the
cursor passes beyond the right margin as set by the user
while text is being inserted
(default).
.IP \fBnomargins\fR
Allows lines to extend beyond the right margin.
.IP \fBautoformat\fR
Causes \fIee\fR to automatically try to format the current paragraph while
text insertion is occurring.
.IP \fBnoautoformat\fR
Turns off automatic paragraph formatting (default).
.IP \fBprintcommand\fR
Allows the setting of the print command (default: "lp").
.IP \fBrightmargin\fR
The user can select a value for the right margin (the first column on the
screen is zero).
.IP \fBhighlight\fR
Turns on highlighting border of information window and menus (default).
.IP \fBnohighlight\fR
Turns off highlighting of border of information window and menus.
.IP \fBeightbit\fR
Turns on display of eight bit characters.
.IP \fBnoeightbit\fR
Turns off display of eight bit characters (they are displayed as their decimal
value inside angle brackets, e.g., "<220>").
.IP \fB16bit\fR
Turns on handling of 16-bit characters.
.IP \fbno16bit\fR

Easy Editor ("ee") provides the ability to translate the messages
displayed to the user and the commands entered. This is done via message
catalogs, following X/Open standards. ee supports eight bit characters,
as well as 16-bit characters. The Chinese Big 5 code set is the 16-bit
code set that ee was modified to handle, as it is relatively easy to
support since two byte characters also take up two columns on the screen,
thereby simplifying the screen position calculations. Other multibyte
code sets may function, but have not been tested.
(The name ee.i18n.guide is for "ee internationalization guide". The i18n
abbreviation is used because there are 18 characters between the first
letter ("i") and last ("n") of "internationalization".)
All of the messages, warnings, information, and commands, are contained
in the message catalog. Each numbered entry represents an individual
string used by ee. Some strings contain formatting information for
formatted print statements, which are of the form "%s", or "%d", these
must be preserved in the translation, or the correct information will not
be displayed. For those strings containing multiple formatting codes,
the order of each item must be preserved as well.

183 menu entry for modes menu for 16 bit characters
184 - 185 strings for initialization to turn on or off 16 bit
character handling
Care should be taken when translating commands and initialization keywords
because the algorithm used for detecting uniqueness of entered commands
will not be able to distinguish words that are not unique before the end
of the shorter word, for example, it would not be able to distinguish the
command 'abcd' from 'abcde'.
After translating the messages, use the 'gencat' command to create the compiled
catalog used when running the software. The standard syntax would be:
gencat ee.cat ee.msg
Where ee.msg is the file containing the translations, and ee.cat is the
compiled catalog. If the file ee.cat does not exist, it will be created.
Check the documentation for your system for proper syntax.
Message catalog placement varies from system to system. A common location
for message catalogs is in /usr/lib/nls. In this directory are
directories with the names of other languages. The default language is
'C'. There is also an environment variable, named NLSPATH used to
determine where message catalogs can be found. This variable is similar
to the PATH variable used for commands, but with some differences. The
NLSPATH variable must have the ability to handle different names for
languages and the catalog files, so it has field descriptors for these. A
typical setting for NLSPATH could be:
NLSPATH=/usr/lib/nls/%L/%N.cat:/usr/local/lib/nls/%L/%N.cat
Where "%L" is the field descriptor for the language (obtained from the
LANG environment variable) and "%N" is the name of the file (with the
".cat" appended by the path variable, it is not passed from the requesting
program). The colon (:) is used to separate paths, so in the above
example there are two paths possible for message catalogs. You may wish
to maintain catalogs for applications that are not supported by your
system vendor in a location unique for you, and this is facilitated by the
NLSPATH variable. Remember to set and export both the LANG and NLSPATH
variables for each user that expects to use localization either in a
system-wide profile or in each user's profile. See your system
documentation for more information.
The message catalog supplied with ee also uses the '$quote' directive to
specify a quote around strings to ensure proper padding. This directive
may not be supported on all systems, and lead to quotes being included in
the string used in ee, which will cause incorrect behavior. If the
'$quote' directive is not supported by your system's gencat command, edit
the msg file to remove the leading and trailing quotation marks.
