@chapter What is Muse?

Emacs Muse is an authoring and publishing environment for Emacs.  It
simplifies the process of writing documents and publishing them to
various output formats.

Muse consists of two main parts: an enhanced text-mode for authoring
documents and navigating within Muse projects, and a set of publishing
styles for generating different kinds of output.

This idea is not in any way new. Numerous systems exist -- even one
other for Emacs itself (Bhl Mode). What Muse adds to the picture is a
more modular environment, with a rather simple core, in which "styles"
are derived from to create new styles. Much of Muse's overall
functionality is optional. For example, you can use the publisher
without the major-mode, or the mode without doing any publishing; or if
you don't load the Texinfo or LaTeX modules, those styles won't be
available.

The Muse codebase is a departure from emacs-wiki.el version 2.44. The
code has been restructured and rewritten, especially its publishing
functions. The focus in this revision is on the authoring and publishing
aspects, and the "wikiness" has been removed as a default behavior
(available in the optional @file{muse-wiki} module). CamelCase words are
no longer special by default.

@cindex arch revision control system, using
The Arch revision control system allows you to retrieve previous
versions and select specific features and bug fixes.  If you would like
to contribute to Muse development, it is highly recommended that you use
Arch, but this is not a requirement.

If you are new to Arch, you might find this tutorial helpful:

@node Installation, Getting Started, Obtaining Muse, Top
@comment  node-name,  next,  previous,  up
@chapter Compiling and Installing Muse

Muse may be compiled and installed on your machine.

@subheading Compilation

This is an optional step, since Emacs Lisp source code does not
necessarily have to be byte-compiled.  It will yield a speed increase,
though.

A working copy of Emacs or XEmacs is needed in order to compile the
Emacs Muse.  By default, the program that is installed with the name
@command{emacs} will be used.

If you want to use the @command{xemacs} binary to perform the
compilation, you would need to edit @file{Makefile.defs} in the
top-level directory as follows.  You can put either a full path to an
Emacs or XEmacs binary or just the command name, as long as it is in the
@env{PATH}.

@example
EMACS    = xemacs
SITEFLAG = -no-site-file
@end example

Running @code{make} should compile the Muse source files in the
@file{lisp} directory.

@subheading Installation

Muse may be installed into your file hierarchy by doing the following.

Edit the @file{Makefile.defs} file so that @env{ELISPDIR} points to
where you want the source and compiled Muse files to be installed and
@env{INFODIR} indicates where to put the Muse manual.  Of course, you
will want to edit @env{EMACS} and @env{SITEFLAG} as shown in the
Compilation section if you are using XEmacs.

If you are installing Muse on a Debian or Ubuntu system, you might want
to change the value of @env{INSTALLINFO} as specified in
@file{Makefile.defs}.

If you wish to install Muse to different locations than the defaults
specify, edit @file{Makefile.defs} accordingly.

Run @code{make} as a normal user.

Run @code{make install} as the root user if you have chosen installation
locations that require this.


@node Getting Started, Projects, Installation, Top

@chapter Getting Started
@cindex settings

To use Muse, add the directory containing its files to your
@code{load-path} variable, in your @file{.emacs} file.  Then, load in
the authoring mode, and the styles you wish to publish to.  An example
follows.

@lisp
(add-to-list 'load-path "<path to Muse>")

(require 'muse-mode)     ; load authoring mode

(require 'muse-html)     ; load publishing styles I use
(require 'muse-latex)
(require 'muse-texinfo)
(require 'muse-docbook)
@end lisp

Once loaded, the command @kbd{M-x muse-publish-this-file} will publish
an input document to any available style.  If you enable
@file{muse-mode} within a buffer, by typing @kbd{M-x muse-mode}, this
command will be bound to @kbd{C-c C-t}.

If the currently opened file is part of a defined project in
@code{muse-project-alist}, it may be published using @kbd{C-c C-p}.

You should also type @kbd{M-x customize-group}, and give the name
@samp{muse}.  Each of the options has its own documentation.


@node Projects, Keystroke Summary, Getting Started, Top
@comment  node-name,  next,  previous,  up
@chapter Creating and Managing Muse Projects
@cindex projects

Often you will want to publish all the files within a directory to a
particular set of output styles automatically.  To support, Muse
allows for the creations of "projects".  Here is a sample project, to
be defined in your @file{.emacs} file.

@lisp
(require 'muse-project)

(setq muse-project-alist
      '(("website"                      ; my various writings
         ("~/Pages" :default "index")
         (:base "html" :path "~/public_html")
         (:base "pdf" :path "~/public_html/pdf"))))
@end lisp

The above defines a project named "website", whose files are located
in the directory @file{~/Pages}.  The default page to visit is
@file{index}.  When this project is published, each page will be
output as HTML to the directory @file{~/public_html}, and as PDF to
the directory @file{~/public_html/pdf}.  Within any project page, you
may create a link to other pages using the syntax @samp{[[pagename]]}.

By default, Muse expects all project files to have the file extension
@file{.muse}. Files without this extension will not be associated with
Muse mode and will not be considered part of any project, even if they
are within a project directory.

If you don't want to use @file{.muse}, you can customize the extension
by setting the value of @code{muse-file-extension}.

If you don't want to use any extension at all, and want Muse to
autodetect project files based on their location, then add the following
to your Muse settings file.

@lisp
(setq muse-file-extension nil
      muse-mode-auto-p t)
@end lisp

If you would like to include only some files from a directory in a Muse
project, you may use a regexp in place of @file{~/Pages} in the example.

@chapter Rules for Using Markup
@cindex markup

A Muse document uses special, contextual markup rules to determine how
to format the output result.  For example, if a paragraph is indented,
Muse assumes it should be quoted.

There are not too many markup rules, and all of them strive to be as
simple as possible so that you can focus on document creation, rather
than formatting.

@section Paragraphs: centering and quoting
@cindex paragraphs

Paragraphs in Muse must be separated by a blank line.

@cindex paragraphs, centered
@subheading Centered paragraphs and quotations

A line that begins with six or more columns of whitespace (either tabs
or spaces) indicates a centered paragraph.  Alternatively, you can use
the @verb{|<center>|} tag to surround regions that are to be published as
centered paragraphs.

@cindex paragraphs, quoted
@cindex quotations
But if a line begins with whitespace, though less than six columns, it
indicates a quoted paragraph.  Alternatively, you can use the
@verb{|<quote>|} tag to surround regions that are to be published as
quoted paragraphs.

@cindex examples
@cindex monospace, rendering blocks
@cindex HTML, rendering blocks in monospace
@subheading Literal paragraphs

The @verb{|<example>|} tag is used for examples, where whitespace should
be preserved, the text rendered in monospace, and any characters special
to the output style escaped.

@cindex literal text
@cindex HTML, inserting a raw block
There is also the @verb{|<literal>|} tag, which causes a marked block to
be entirely left alone.  This can be used for inserting a hand-coded
HTML blocks into HTML output, for example.

@node Headings, Directives, Paragraphs, Markup Rules
@comment  node-name,  next,  previous,  up
@section Levels of headings
@cindex headings

A heading becomes a chapter or section in printed output -- depending on
the style.  To indicate a heading, start a new paragraph with one or
more asterices, followed by a space and the heading title.  Then begin
another paragraph to enter the text for that section.

All levels of headings will be published.  Most publishing styles only
distinguish the between the first 4 levels, however.

@example
* First level

** Second level

*** Third level

**** Fourth level
@end example

@node Directives, Emphasizing Text, Headings, Markup Rules
@comment  node-name,  next,  previous,  up
@section Directives at the beginning of a document
@cindex directives

Directives are lines beginning with the @samp{#} character that come
before any paragraphs or sections in the document.  Directives are of
the form ``#directive content of directive''.  You can use any
combination of uppercase and lowercase letters for directives, even if
the directive is not in the list below.

The @code{muse-publishing-directive} function may be used in header and
footer text to access directives.  For example, to access the
@samp{#title} directive, use @code{(muse-publishing-directive "title")}.

The following is a list of directives that Muse uses.

@table @code
@cindex #author
@item #author
The author of this document.

If this is not specified, Muse will attempt to figure it out from the
@code{user-full-name} variable.

@cindex #date
@item #date
The date that the document was last modified.

This is used by publishing styles that are able to embed the date
information.

@cindex #desc
@item #desc
A short description of this document.

This is used by the @code{journal} publishing style to embed information
inside of an RSS/RDF feed.

@cindex #title
@item #title
The title of this document.

If this is not specified, the name of the file is used.

@end table

@section Bold, italicized, and underlined text
@cindex emphasizing text
@cindex underlining text
@cindex italicizing text
@cindex verbatim text
@cindex monospace, rendering words

To emphasize text, surround it with certain specially recognized
characters.

@example
*emphasis*
**strong emphasis**
***very strong emphasis***
_underlined_
=verbatim and monospace=
@end example

@cindex WYSIWYG
While editing a Muse document in Muse mode, these forms of emphasis will
be highlighted in a WYSIWYG manner.  Each of these forms may span
multiple lines.

Verbatim text will be colored as gray by default.  To change this,
customize @code{muse-verbatim-face}.

You can also use the @verb{|<code>|} tag to indicate verbatim and
monospace text.  This is handy for regions that have an ``='' in them.

@node Footnotes, Verse, Emphasizing Text, Markup Rules
@comment  node-name,  next,  previous,  up
@section Making notes to be shown at the end
@cindex footnotes

A footnote reference is simply a number in square brackets.  To define
the footnote, place this definition at the bottom of your file.
@samp{footnote-mode} can be used to greatly facilitate the creation of
these kinds of footnotes.

Footnotes are defined by the same number in brackets occurring at the
beginning of a line.  Use footnote-mode's @kbd{C-c ! a} command, to very
easily insert footnotes while typing.  Use @kbd{C-x C-x} to return to
the point of insertion.

@node Verse, Lists, Footnotes, Markup Rules
@comment  node-name,  next,  previous,  up
@section Indicating poetic stanzas
@cindex verses
@cindex poetry

Poetry requires that whitespace be preserved, but without resorting to
monospace.  To indicate this, use the following markup, reminiscent of
email quotations.

@example
> A line of Emacs verse;
>   forgive its being so terse.
@end example

You can also use the @verb{|<verse>|} tag, if you prefer.

@example
<verse>
A line of Emacs verse;
  forgive its being so terse.
</verse>
@end example

@cindex verses, multiple stanzas
Multiple stanzas may be included in one set of @verb{|<verse>|} tags, as
follows.

@example
<verse>
A line of Emacs verse;
  forgive its being so terse.

In terms of terse verse,
  you could do worse.

Only very simple tables are supported.  The syntax is as follows.

@example
Double bars  || Separate header fields

Single bars   | Separate body fields
Here are more | body fields

Triple bars ||| Separate footer fields
@end example

Some publishing styles require header fields to come first, then footer
fields, and then the body fields.  You can use any order for these
sections that you like, and Muse will re-order them for you at
publish-time.

If you wish to disable table generation for one Muse file, add the
directive @samp{#disable-tables t} to the top of the file.

@node Explicit Links, Implicit Links, Tables, Markup Rules
@comment  node-name,  next,  previous,  up
@section Hyperlinks and email addresses with descriptions
@cindex links, explicit

A hyperlink can reference a URL, or another page within a Muse
project.  In addition, descriptive text can be specified, which should
be displayed rather than the link text in output styles that supports
link descriptions.  The syntax is as follows.

@example
[[link target][link description]]
[[link target without description]]
@end example

Thus, the current maintainer's homepage for Muse can be found
@samp{[[http://www.mwolson.org/projects/EmacsMuse.html][here]]},
or at @samp{[[http://www.mwolson.org/projects/EmacsMuse.html]]}.

@cindex URLs
@cindex Email addresses

A URL or email address encountered in the input text is published as a
hyperlink.  These kind of links are called @dfn{implicit links} because
they are not separated from the rest of the Muse document in any way.

Some characters in URLs will prevent Muse from recognizing them as
implicit links. If you want to link to a URL containing spaces or any of
the characters ``][,"'`()<>^'', you will have to make the link
explicit. The punctuation characters ``.,;:'' are also not recognized as
part of a URL when they appear at its end. For information on how to
make an explicit link, see @ref{Explicit Links,,Hyperlinks and email
addresses with descriptions}.

@cindex WikiNames
If the @command{muse-wiki} module is loaded, another form of implicit
link will be made available.  WikiNames, which are typed in CamelCase,
are highlighted and published as links, provided that the file they
refer to exists.

Customization of WikiName recognition may be accomplished by editing the
@code{muse-wiki-wikiword-regexp} option and subsequently running
@code{(muse-configure-highlighting 'muse-colors-markupmuse-colors-markup)}.
If you use the Customize interface, the latter will be done
automatically.

@cindex InterWiki links
@cindex inter-project links
The @command{muse-wiki} module also allows for InterWiki links.  These
are similar to WikiWords, but they specify both the project and page of
a file.  The names of your project entries in @code{muse-project-alist}
will be used as InterWiki names by default.  Several examples follow.

@example
Blog::DocumentingMuse
Projects#EmacsMuse
Website
@end example

In the first case, the interwiki delimiter is @samp{::}, @samp{Blog} is
the project name, and @samp{DocumentingMuse} is the page name.  In the
second example, @samp{#} is the interwiki delimiter.  If the name of a
project occurs by itself in text, like the third case, it will be
colorized and published as a link to the default page of the given
project.

Customization of interwiki links may be accomplished by editing the
@code{muse-wiki-interwiki-alist} option.

@section Publishing and displaying images

@cindex links, with images
@subheading Image links

Links to images may be used in either the target or the description, or
both.  Thus, the following code will publish as a clickable image that
points to @url{http://www.mwolson.org/}.

@example
[[http://www.mwolson.org/][/static/logos/site-logo.png]]
@end example

@cindex images, displaying
@cindex images, local
@subheading Displaying images in Muse mode
If a link to a locally-available image is encountered in the link
description, Muse mode will attempt to display it if your version of
Emacs permits this.

This behavior may be toggled with @kbd{C-c C-i}, or disabled permanently
by setting the @code{muse-colors-inline-images} option to @code{nil}.

The method for finding images may be altered by customizing the
@code{muse-colors-inline-image-method} option.  One useful value for
this option is @code{muse-colors-use-publishing-directory}, which tells
Muse mode to look in the directory where the current file will be
published.  The default is to look in the current directory.  Relative
paths like @samp{../pics/} should work for either setting.

Eventually, it is hoped that Muse will be able to copy images from the a
``source'' directory to a publishing directory by customizing
@code{muse-project-alist}, but this has not been implemented yet.

@cindex images, without descriptions
@cindex images, inlined
@subheading Publishing simple images
The following example will display correctly and publish correctly if a
@acronym{PNG} file called @file{TestLogo.png} exists in the
@file{../pics/} directory.  If text is on the same line as the picture,
it will remain so in the output.

@example
[[../myimage.png]]
@end example

@cindex images, captions
@subheading Publishing images with captions
If you want to add a caption to an image, use the following syntax.
This will center the image (if the output format supports it) and add a
centered caption below the picture.  Formats that do not support
centering the image will instead leave it against the left margin.

@example
[[../pics/mycat.png][My cat Dexter]]
@end example

Images with captions may only occur in their own paragraphs, with no
text on the same line.  Otherwise, the published output will not be
syntactically correct.

Arbitrary kinds of markup can be achieved using the @verb{|<lisp>|} tag,
which is the only Muse tag supported in a style's header and footer
text.  With the @verb{|<lisp>|} tag, you may generated whatever output
text you wish.  The inserted output will get marked up, if the
@verb{|<lisp>|} tag appears within the main text of the document.

@example
<lisp>(concat "This form gets " "inserted")</lisp>
@end example

@cindex lisp, and insert command
Note that you should not use the @code{insert} command within a set of
@verb{|<lisp>|} tags, since the return value from the @verb{|<lisp>|}
tags will be automatically inserted into the document.

@section Tags that Muse recognizes

@cindex publishing, inserting files

Muse has several built-in tags that may prove useful during publishing.
@xref{muse-publish-markup-tags}, to see how to customize the tags that
Muse uses, as well as make your own tags.

@subheading Syntax

If a tag takes arguments, it will look like this, where ``tagname'' is
the name of the tag.

@example
<tagname arg1="string1" arg2="string2">
@end example

If you want the tag to look like it came straight from an XHTML
document, you can alternatively do the following.

@example
<tagname arg1="string1" arg2="string2" />
@end example

If a tag surrounds some text, it will look like this.

@example
<tagname>Some text</tagname>
@end example

If a tag surrounds a large region, it will look like this.

@example
<tagname>
Some text.
Some more text.
</tagname>
@end example

@subheading Tag listing

This is the complete list of tags that Muse accepts, including those
that were mentioned in previous sections.

@table @samp

@item <class>
If publishing to HTML, surround the given text with a @verb{|<span>|}
tag.  It takes one argument called ``name'' that specifies the class
attribute of the @verb{|<span>|} tag.

If publishing to a different format, do nothing extra to the text.

@item <code>
Treat the text surrounded by the tag as if they were enclosed in equal
signs, that is, make it monospace.

@item <command>
Run a command on the region, replacing the region with the result of the
command.  The command is specified with the ``interp'' argument.  If no
value for ``interp'' is given, pass the entire region to the shell.

The ``markup'' argument controls how this section is marked up.

If it is omitted, publish the region with the normal Muse rules.

If "nil", do not mark up the region at all, but prevent Muse from
further interpreting it.

If "example", treat the region as if it was surrounded by the
@verb{|<example>|} tag.

If "verse", treat the region as if it was surrounded by the
@verb{|<verse>|} tag, to preserve newlines.

Otherwise, it should be the name of a function to call, with the buffer
narrowed to the region.

@item <comment>
Treat the entire region as a comment.  If the option
@var{muse-publish-comments-p} is nil, delete the region, otherwise
publish it using the comment syntax of the current publishing style.

@item <contents>
Publish a Table of Contents.  This will either be inserted in-place or
at the beginning of the document, depending on your publishing style.
It does not have a delimiting tag.

By default, only 2 levels of headings will be included in the generated
Table of Contents.  To change this globally, customize the
@var{muse-publish-contents-depth} option.  To change this only for the
current tag, use the ``depth'' argument.

@item <example>
Publish the region in monospace, preserving the newlines in the region.
This is useful for snippets of code.

@item <include>
Insert the given file at the current location during publishing.  The
basic use of this tag is as follows, replacing ``included_file'' with
the name of the file that you want to include.

@example
<include file="included_file">
@end example

The ``markup'' argument controls how this section is marked up.

If it is omitted, publish the included text with the normal Muse
rules.

If "nil", do not mark up the included text at all.

If "example", treat the included text as if it was surrounded by the
@verb{|<example>|} tag.

If "verse", treat the included text as if it was surrounded by the
@verb{|<verse>|} tag, to preserve newlines.

Otherwise, it should be the name of a function to call after inserting
the file with the buffer narrowed to the section inserted.

@item <lisp>
Evaluate the Emacs Lisp expressions between the initial and ending tags.
The result is then inserted into the document, so you do not need to
explicitly call @code{insert}.  All text properties are removed from the
resulting text.

This tag takes the ``markup'' argument.  See the description of
@verb{|<command>|} for details.

@item <literal>
Make sure that the text enclosed by this tag is published without
escaping it in any way.  This is useful for inserting markup directly
into the published document, when Muse does not provide the desired
functionality.

@item <markup>
Mark up the text between the initial and ending tags.  The markup
command to use may be specified by the ``function'' argument.  The
standard Muse markup routines are used by default if no ``function''
argument is provided.

This is useful for marking up regions in headers and footers.  One
example that comes to mind is generating a published index of all of the
files in the current project by doing the following.

@example
<markup><lisp>(muse-index-as-string t t)</lisp></markup>
@end example

@item <perl>
Run the @command{perl} language interpreter on the region, replacing the
region with the result of the command.

This tag takes the ``markup'' argument.  See the description of
@verb{|<command>|} for details.

@item <python>
Run the @command{python} language interpreter on the region, replacing
the region with the result of the command.

This tag takes the ``markup'' argument.  See the description of
@verb{|<command>|} for details.

@item <quote>
Publish the region as a blockquote.  This will either be inserted
in-place or at the beginning of the document, depending on your
publishing style.  It does not have a delimiting tag.

@item <ruby>
Run the @command{ruby} language interpreter on the region, replacing the
region with the result of the command.

This tag takes the ``markup'' argument.  See the description of
@verb{|<command>|} for details.

@item <verbatim>
This is used when you want to prevent Muse from trying to interpret some
markup.  Surround the markup in @verb{|<verbatim>|} and
@verb{|</verbatim>|}, and it will not be interpreted.

This tag was used often in previous versions of Muse because they did
not support whole-document escaping of specials.  Now, it will only be
needed for other tags, and perhaps footnotes as well.

@item <verse>
Preserve the newlines in the region.  In formats like HTML, newlines are
removed by default, hence the need for this tag.  In other publishing
styles, this tag may cause the text to be indented slightly in a way
that looks nice for poetry and prose.

@subsection Other tools needed for the Blosxom style

You will need to have @command{pyblosxom.cgi} or @command{blosxom.cgi}
installed on a machine that you have upload access to.

The following additional components are required in order to make the
date of blog entries display as something sensible.

@enumerate
@item
A script to gather date directives from the entire blog tree into a
single file.  The file must associate a blog entry with a date.

@item
A plugin for (py)blosxom that reads this file.
@end enumerate

These 2 things are provided for @command{pyblosxom.cgi} in the
@file{contrib/pyblosxom} subdirectory.  @file{getstamps.py} provides the
former service, while @file{hardcodedates.py} provides the latter
service.  Eventually it is hoped that a @command{blosxom.cgi} plugin and
script will be found/written.

Here is a sample listing from my @file{timestamps} file, which maps
each file to a date.  This can really be in any format, as long as your
date-gathering script and your plugin can both understand it.

@example
2005-04-01-14-16 personal/paper_cranes
2005-03-21 personal/spring_break_over
2004-10-24 personal/finished_free_culture
@end example

The script @file{contrib/pyblosxom/make-blog} demonstrates how to call
@file{getstamps.py}.  Note that you will need to set the current
directory to where your Muse files are, execute @file{getstamps.py}, and
then move the generated timestamps file to your publishing directory.

@node Blosxom Entries, Blosxom Options, Blosxom Requirements, Blosxom

@subsection Format of a Blosxom entry and automation

Each Blosxom file must include `#date yyyy-mm-dd', or optionally the
longer `#date yyyy-mm-dd-hh-mm', a title (using the #title directive),
plus whatever normal content is desired.

The date directive is not used directly by @command{pyblosxom.cgi} or
this program.  You need to have the two additional items from the former
section to make use of this feature.

There is a function called @code{muse-blosxom-new-entry} that will
automate the process of making a new blog entry.  To make use of it, do
the following.

@itemize @bullet
@item
Customize @code{muse-blosxom-base-directory} to the location that your
blog entries are stored.

@item
Assign the @code{muse-blosxom-new-entry} function to a key sequence.  I
use the following code to assign this function to @kbd{C-c p l'}.

@example
(global-set-key "\C-cpl" 'muse-blosxom-new-entry)
@end example

@item
You should create your directory structure ahead of time under your base
directory.  These directories, which correspond with category names, may
be nested.

@item
When you enter this key sequence, you will be prompted for the category
of your entry and its title.  Upon entering this information, a new file
will be created that corresponds with the title, but in lowercase
letters and having special characters converted to underscores.  The
title and date directives will be inserted automatically.

The plurality of "div" tags makes it possible to display the entries in
any form you wish, using a CSS style.

Also, an .RDF file can be generated from your journal by publishing it
with the "rdf" style.  It uses the first two sentences of the first
paragraph of each entry as its "description", and auto-generates tags
for linking to the various entries.

ignore the @verb{|<contents>|} tag.

@section Publish a poem to LaTex or PDF

The @code{muse-poem} module makes it easy to attractively publish and
reference poems in the following format, using the "memoir" module for
LaTeX publishing.  It will also markup poems for every other output
style, though none are nearly as pretty.

@example
Title


Body of poem


Annotations, history, notes, etc.
@end example

Once a poem is written in this format, just publish it to PDF using the
@code{poem-pdf} style.  To make an inlined reference to a poem that
you've written -- for example, from a blog page -- there is a "poem" tag
defined by this module.

@example
<poem title="name.of.poem.page">
@end example

Let's assume the template above was called @file{name.of.poem.page};
then the above tag would result in this inclusion.

@example
** Title

> Body of poem

John Wiegley uses this module for publishing all of the poems on his
website, which are at

rules for the most common types of markup.

Each member of the list is of the following form.

@example
(SYMBOL FUNCTION)
@end example

@itemize @bullet
@item SYMBOL
Describes the type of text to associate with this rule.
@code{muse-publish-markup-regexps} maps regexps to these symbols.

@anchor{muse-publish-markup-regexps}
@code{muse-publish-markup-regexps}

List of markup rules for publishing a page with Muse.

The rules given in this variable are invoked first, followed by whatever
rules are specified by the current style.

Each member of the list is either a function, or a list of the following
form.

@example
(REGEXP/SYMBOL TEXT-BEGIN-GROUP REPLACEMENT-TEXT/FUNCTION/SYMBOL)
@end example

@itemize @bullet
@item REGEXP
A regular expression, or symbol whose value is a regular expression,
which is searched for using `re-search-forward'.

@item TEXT-BEGIN-GROUP
The matching group within that regexp which denotes the beginning of the
actual text to be marked up.

@item REPLACEMENT-TEXT
A string that will be passed to `replace-match'.

If it is not a string, but a function, it will be called to determine
what the replacement text should be (it must return a string).  If it is
a symbol, the value of that symbol should be a string.
@end itemize

The replacements are done in order, one rule at a time.  Writing
the regular expressions can be a tricky business.  Note that case
is never ignored.  `case-fold-search' is always bound to nil
while processing the markup rules.

@subheading Publishing order

This is the order that the publishing rules are consulted, by default.
This may be changed by customizing @code{muse-publish-markup-regexps}.

This function is responsible for marking up emphasis and escaping some
specials.

@code{muse-publish-markup-tags}

A list of tag specifications, for specially marking up text.

XML-style tags are the best way to add custom markup to Muse.  This is
easily accomplished by customizing this list of markup tags.

For each entry, the name of the tag is given, whether it expects a
closing tag and/or an optional set of attributes, whether it is
nestable, and a function that performs whatever action is desired within
the delimited region.

The tags themselves are deleted during publishing, before the function
is called.  The function is called with three arguments, the beginning
and end of the region surrounded by the tags.  If properties are
allowed, they are passed as a third argument in the form of an alist.
The `end' argument to the function is always a marker.

Point is always at the beginning of the region within the tags, when the
function is called.  Wherever point is when the function finishes is
where tag markup will resume.

These tag rules are processed once at the beginning of markup, and once
at the end, to catch any tags which may have been inserted in-between.

@cindex publishing styles, deriving

To create a new style from an existing one, use @code{muse-derive-style}
as follows.  This is a good way to fix something you don't like about a
particular publishing style, or to personalize it.

@example
(muse-derive-style DERIVED-NAME BASE-NAME STYLE-PARAMETERS)
@end example

The derived name is a string defining the new style, such as "my-html".
The base name must identify an existing style, such as "html" -- if you
have loaded @file{muse-html}.  The style parameters are the same as
those used to create a style, except that they override whatever
definitions exist in the base style.  However, some definitions only
partially override.  The following parameters support partial
overriding.

@xref{Style Elements}, for a complete list of all parameters.

@table @option

@item :functions
If a markup function is not found in the derived style's function list,
the base style's function list will be queried.

@item :regexps
All regexps in the current style and the base style(s) will be used.

@item :strings
If a markup string is not found in the derived style's string list, the
base style's string list will be queried.

Muse-specific help, and its current maintainer hangs out there.

@item
The maintainer of Emacs Muse, Michael Olson, may be contacted at
@email{mwolson@@gnu.org}.  He can be rather slow at answering email, so
it is often better to use the muse-el-discuss mailing list.

@item 2004
John Wiegley started Muse upon realizing that EmacsWiki had some serious
limitations. Around February 2004, he started making "emacs-wiki version
3.00 APLHA", which eventually became known as Muse.

Most of those who frequent the emacs-wiki mailing list continued to use
emacs-wiki, mainly because Planner hasn't been ported over to it.

As of 2004-12-01, Michael Olson became the maintainer of Muse, as per
John Wiegley's request.

@item 2005
Michael Olson overhauled this document and added many new sections in
preparation for the first release of Muse (3.01).

@cindex GNU General Public License

@c This file is intended to be included in another file.

@display
Copyright @copyright{} 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
@end display

@appendixsec Preamble

  The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software---to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.)  You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

  To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.

  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have.  You must make sure that they, too, receive or can get the
source code.  And you must show them these terms so they know their
rights.

  We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

  Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.

  Finally, any free program is threatened constantly by software
patents.  We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary.  To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.

  The precise terms and conditions for copying, distribution and
modification follow.

@iftex
@appendixsec TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
@end iftex
@ifinfo
@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
@end ifinfo

@enumerate 0
@item
This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License.  The ``Program'', below,
refers to any such program or work, and a ``work based on the Program''
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language.  (Hereinafter, translation is included without limitation in
the term ``modification''.)  Each licensee is addressed as ``you''.

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

@item
You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

@item
You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

@enumerate a
@item
You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.

@item
You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.

@item
If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License.  (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
@end enumerate

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.

In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

@item
You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:

@enumerate a
@item
Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,

@item
Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,

@item
Accompany it with the information you received as to the offer
to distribute corresponding source code.  (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
@end enumerate

The source code for a work means the preferred form of the work for
making modifications to it.  For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable.  However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.

If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.

@item
You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.

@item
You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Program or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.

@item
Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.

@item
If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all.  For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

@item
If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded.  In such case, this License incorporates
the limitation as if written in the body of this License.

@item
The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

Each version is given a distinguishing version number.  If the Program
specifies a version number of this License which applies to it and ``any
later version'', you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation.  If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.

@item
If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission.  For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this.  Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY

OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM ``AS IS'' WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF

TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.

@item
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR

INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING

@appendixsec Appendix: How to Apply These Terms to Your New Programs

  If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the ``copyright'' line and a pointer to where the full notice is found.

@smallexample
@var{one line to give the program's name and a brief idea of what it does.}
Copyright (C) @var{yyyy}  @var{name of author}

This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.

This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
GNU General Public License for more details.

You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA.
@end smallexample

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

@smallexample
Gnomovision version 69, Copyright (C) 19@var{yy} @var{name of author}
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
@end smallexample

The hypothetical commands @samp{show w} and @samp{show c} should show
the appropriate parts of the General Public License.  Of course, the
commands you use may be called something other than @samp{show w} and
@samp{show c}; they could even be mouse-clicks or menu items---whatever
suits your program.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a ``copyright disclaimer'' for the program, if
necessary.  Here is a sample; alter the names:

@example
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

@var{signature of Ty Coon}, 1 April 1989
Ty Coon, President of Vice
@end example

This General Public License does not permit incorporating your program into
proprietary programs.  If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library.  If this is what you want to do, use the GNU Library General
Public License instead of this License.
