<indent>Emacs has the ability to edit <italic>enriched text</italic>, which is text
|
||
containing faces, colors, indentation, and other properties.
|
||
This document is a quick introduction to some of the features,
|
||
and is also an example file in the <italic>text/enriched </italic>format.</indent>
|
||
|
||
|

|
||
|
||
|
||
<indent>Most of the time, you need not do anything to get these features
|
||
to work. If you visit a file that has been written out in
|
||
<italic>text/enriched</italic> format, it will automatically be decoded, Emacs will
|
||
enter 'enriched-mode' while visiting it, and whenever you save it
|
||
it will be saved in the same format it was read in.
|
||
|
||
If you wish to create a new file, however, you will need to turn
|
||
on enriched-mode yourself:
|
||
|
||
|
||
<fixed><indent>M-x enriched-mode RET</indent></fixed>
|
||
|
||
|
||
Or, if you get a <italic>text/enriched </italic>file that Emacs does not
|
||
automatically recognize and decode, you can tell Emacs to decode
|
||
it (which also turns on enriched-mode automatically):
|
||
|
||
|
||
<fixed><indent>M-x format-decode-buffer RET text/enriched RET</indent></fixed></indent>

|

|
||
|
||
<indent>Here is the current list of text-properties that are saved; they
|
||
are discussed in more detail below. Most of these can be added or
|
||
changed with the "Text Properties" menu, available under the
|
||
"Edit" item in the menu-bar, or on C-mouse-2 (Control + the middle
|
||
mouse button).

|
||
|
||
|
||
<indent>You can add faces either with the menu or with <fixed>M-o.</fixed> The face is
|
||
applied to the current region. If you are using
|
||
'transient-mark-mode' and the region is not active, then the face
|
||
applies to whatever you type next. Any face can have colors. If
|
||
this is its lone attribute, the face is put on the color submenus
|
||
of the "Text Properties" menu.</indent>

|

|
||
|
||
<italic><indent>Text/enriched</indent></italic><indent> format distinguishes between <underline>hard</underline> and <underline>soft</underline> newlines.
|
||
Hard newlines are used to separate paragraphs, or items in a list,
|
||
or anywhere that must be a line break no matter what the margins
|
||
are. Soft newlines are the ones inserted in order to fit text
|
||
between the margins. The fill and auto-fill functions insert soft
|
||
newlines as necessary, but hard newlines are only inserted by
|
||
direct request, such as using the return key or the <fixed>C-o
|
||
(open-line)</fixed> function.</indent>

|
||
|
||
|
||
<indent>The fill functions also understand margins, which can be set for
|
||
any region of a document. In addition to the menu items, which
|
||
increase or decrease the margins, there are two commands for
|
||
setting the margins absolutely: <fixed>C-c [ (set-left-margin)</fixed> and <fixed>C-c
|
||
] (set-right-margin)</fixed>.
|
||
|
||
|
||
You <indent>can change indentation at any point in a paragraph, which
|
||
makes it possible to do interesting things like
|
||
hanging-indents: this paragraph was indented by selecting the
|
||
region from the second word to the end of the paragraph, and
|
||
indenting only that part.</indent></indent>

|

|

|

<indent><nofill>Several styles of justification are possible, the simplest being <italic>unfilled.
|
||
</italic>This means that your lines will be left as you write them.
|
||
This paragraph is unfilled.</nofill>
|
||
|
||
|
||
<flushleft>The most common (for English) style is <italic>FlushLeft. </italic>This means
|
||
lines are aligned at the left margin but left uneven at the right.</flushleft>
|
||
|
||
|
||
<flushright> <italic>FlushRight</italic> makes each line flush with the right margin instead.
|
||
This paragraph is FlushRight.</flushright>
|
||
|
||
|
||
<flushboth><italic>FlushBoth </italic>regions, which are sometimes called "fully justified"
|
||
are aligned evenly on both edges, so that the text on the page has
|
||
a smooth appearance as in a book or newspaper article.
|
||
Unfortunately this does not look as nice with a fixed-width font
|
||
as it does in a proportionally-spaced printed document; the extra
|
||
spaces that are needed on the screen can make it hard to read.</flushboth>
|
||
|
||
<center>
|
||
|
||
<bold>Center</bold>
|
||
|
||
Finally, there is <italic>center </italic>justification. The normal
|
||
center-paragraph key, M-S, can be used to turn on center
|
||
justification in enriched-mode.
|
||
|
||
M-j or the "Text Properties" menu also can be used to change
|
||
justification.
|
||
|
||
|
||
|
||
</center><flushboth>Note that justification can only change at hard newlines, because
|
||
that is the unit over which filling gets done.</flushboth></indent>

<indent>You can add character set information to stretches of text; this
|
||
is important for selecting the font that will display that text.
|

Users of various charsets, especially in East Asian cultures,

prefer the same characters to be rendered differently depending on
|
||
the language/charset context.</indent>

|
||
|
||
|
||
<indent>Enriched-mode documents are saved in an extended version of a
|
||
format called <italic>text/enriched</italic>, which is defined as part of the MIME
|
||
standard. This means that your documents are transportable (even
|
||
through email) to many other systems. In the future other file
|
||
formats may be supported as well.
|
||
|
||
|
||
Since Emacs adds some non-standard features to the format (colors
|
||
and read-only regions), not all systems will be able to recreate
|
||
all of the features of your document, but they will get as close
|
||
as possible.
|
||
|
||
|
||
The text/enriched standard is defined in </indent>Internet<indent> RFC 1896
|
||
(<<http://www.ietf.org/rfc/rfc1896.txt>).</indent>

additions to <fixed>enriched-translations</fixed>. Note that the standard
|

requires you to name your annotation starting<italic> "x-" </italic>(as in
|
||
<italic>"x-read-only"</italic>). Please report any such additions that you
|

think might be of general interest using <fixed>M-x report-emacs-bug</fixed>.</indent>

|

|
||
+ Conform to updated text/enriched spec in RFC 1896.
|
||
|
||
+ Be smarter about fixing malformed files.
|
||
|
||
+ Make the indentation work more seamlessly and robustly:
|
||
|
||
+ Create<indent> an aggressive auto-fill function that will keep the
|
||
paragraph properly filled all the time, without slowing down
|
||
editing too much. Refill mode is a start at this, but needs
|
||
|
||
</indent></indent> <indent>improvement.
|
||
|
||
+ Refill after yank. [Refill mode does that.]
|
||
|
||
+<indent> Make deleting a newline also delete the indentation following
|
||
it.</indent>
|
||
|
||
+ Never let point enter indentation??
|
||
|
||
+ Notice and re-fill when window changes widths (optionally).
|
||
|
||
+ Deal with the 'category' text-property in a smart way.
|
||
|
||
+ Interface w/ Gnus, VM, RMAIL. Maybe Info too? </indent>(Gnus 5.9 copes
|
||
|
||
with text/enriched incoming mail.)<indent>
|
||
|
||
+ Support more formats: RTF, HTML...
|
||
|
||
+ Use modern Emacs display features.
