(defvar org-publish-temp-files nil

|
||
(defvar org-publish-cache nil
|
||
"This will cache timestamps and titles for files in publishing projects.
|
||
Blocks could hash sha1 values here.")
|
||
|
||
(defvar org-publish-after-publishing-hook nil
|
||
"Hook run each time a file is published.
|
||
Every function in this hook will be called with two arguments:
|
||
the name of the original file and the name of the file
|
||
produced.")
|
||
|
||
(defgroup org-publish nil
|
||
"Options for publishing a set of files."
|
||
:tag "Org Publishing"
|
||
:group 'org)
|
||
|
||
(defcustom org-publish-project-alist nil
|
||
"Association list to control publishing behavior.
|
||
\\<org-mode-map>
|
||
Each element of the alist is a publishing project. The car of
|
||
each element is a string, uniquely identifying the project. The
|
||
cdr of each element is in one of the following forms:
|
||
|
||
1. A well-formed property list with an even number of elements,
|
||
alternating keys and values, specifying parameters for the
|
||
publishing process.
|
||
|
||
(:property value :property value ... )
|
||
|
||
2. A meta-project definition, specifying of a list of
|
||
sub-projects:
|
||
|
||
(:components (\"project-1\" \"project-2\" ...))
|
||
|
||
When the CDR of an element of org-publish-project-alist is in
|
||
this second form, the elements of the list after `:components'
|
||
are taken to be components of the project, which group together
|
||
files requiring different publishing options. When you publish
|
||
such a project with `\\[org-publish]', the components all publish.
|
||
|
||
When a property is given a value in `org-publish-project-alist',
|
||
its setting overrides the value of the corresponding user
|
||
variable (if any) during publishing. However, options set within
|
||
a file override everything.
|
||
|
||
Most properties are optional, but some should always be set:
|
||
|
||
`:base-directory'
|
||
|
||
Directory containing publishing source files.
|
||
|
||
`:base-extension'
|
||
|
||
Extension (without the dot!) of source files. This can be
|
||
a regular expression. If not given, \"org\" will be used as
|
||
default extension. If it is `any', include all the files,
|
||
even without extension.
|
||
|
||
`:publishing-directory'
|
||
|
||
Directory (possibly remote) where output files will be
|
||
published.
|
||
|
||
If `:recursive' is non-nil files in sub-directories of
|
||
`:base-directory' are considered.
|
||
|
||
The `:exclude' property may be used to prevent certain files from
|
||
being published. Its value may be a string or regexp matching
|
||
file names you don't want to be published.
|
||
|
||
The `:include' property may be used to include extra files. Its
|
||
value may be a list of filenames to include. The filenames are
|
||
considered relative to the base directory.
|
||
|
||
When both `:include' and `:exclude' properties are given values,
|
||
the exclusion step happens first.
|
||
|
||
One special property controls which back-end function to use for
|
||
publishing files in the project. This can be used to extend the
|
||
set of file types publishable by `org-publish', as well as the
|
||
set of output formats.
|
||
|
||
`:publishing-function'
|
||
|
||
Function to publish file. Each back-end may define its
|
||
own (i.e. `org-latex-publish-to-pdf',
|
||
`org-html-publish-to-html'). May be a list of functions, in
|
||
which case each function in the list is invoked in turn.
|
||
|
||
Another property allows you to insert code that prepares
|
||
a project for publishing. For example, you could call GNU Make
|
||
on a certain makefile, to ensure published files are built up to
|
||
date.
|
||
|
||
`:preparation-function'
|
||
|
||
Function to be called before publishing this project. This
|
||
may also be a list of functions. Preparation functions are
|
||
called with the project properties list as their sole
|
||
argument.
|
||
|
||
`:completion-function'
|
||
|
||
Function to be called after publishing this project. This
|
||
may also be a list of functions. Completion functions are
|
||
called with the project properties list as their sole
|
||
argument.
|
||
|
||
Some properties control details of the Org publishing process,
|
||
and are equivalent to the corresponding user variables listed in
|
||
the right column. Back-end specific properties may also be
|
||
included. See the back-end documentation for more information.

The following properties may be used to control publishing of
|
||
a site-map of files or summary page for a given project.
|
||
|
||
`:auto-sitemap'
|
||
|
||
Whether to publish a site-map during
|
||
`org-publish-current-project' or `org-publish-all'.
|
||
|
||
`:sitemap-filename'
|
||
|
||
Filename for output of sitemap. Defaults to \"sitemap.org\".
|
||
|
||
`:sitemap-title'
|
||
|
||
Title of site-map page. Defaults to name of file.
|
||
|
||
`:sitemap-function'
|
||
|
||
Plugin function to use for generation of site-map. Defaults
|
||
to `org-publish-org-sitemap', which generates a plain list of
|
||
links to all files in the project.
|
||
|
||
`:sitemap-style'
|
||
|
||
Can be `list' (site-map is just an itemized list of the
|
||
titles of the files involved) or `tree' (the directory
|
||
structure of the source files is reflected in the site-map).
|
||
Defaults to `tree'.
|
||
|
||
`:sitemap-sans-extension'
|
||
|
||
Remove extension from site-map's file-names. Useful to have
|
||
cool URIs (see http://www.w3.org/Provider/Style/URI).
|
||
Defaults to nil.
|
||
|
||
If you create a site-map file, adjust the sorting like this:
|
||
|
||
`:sitemap-sort-folders'
|
||
|
||
Where folders should appear in the site-map. Set this to
|
||
`first' (default) or `last' to display folders first or last,
|
||
respectively. Any other value will mix files and folders.
|
||
|
||
`:sitemap-sort-files'
|
||
|
||
The site map is normally sorted alphabetically. You can
|
||
change this behavior setting this to `anti-chronologically',
|
||
`chronologically', or nil.
|
||
|
||
`:sitemap-ignore-case'
|
||
|
||
Should sorting be case-sensitive? Default nil.
|
||
|
||
The following property control the creation of a concept index.
|
||
|
||
`:makeindex'
|
||
|
||
Create a concept index. The file containing the index has to
|
||
be called \"theindex.org\". If it doesn't exist in the
|
||
project, it will be generated. Contents of the index are
|
||
stored in the file \"theindex.inc\", which can be included in
|
||
\"theindex.org\".
|
||
|
||
Other properties affecting publication.
|
||
|
||
`:body-only'
|
||
|
||
Set this to t to publish only the body of the documents."
