23 ;;; Commentary:
25 ;; This program allow configurable publishing of related sets of
26 ;; Org-mode files as a complete website.
28 ;; org-publish.el can do the following:
30 ;; + Publish all one's org-files to HTML or PDF
31 ;; + Upload HTML, images, attachments and other files to a web server
32 ;; + Exclude selected private pages from publishing
33 ;; + Publish a clickable sitemap of pages
34 ;; + Manage local timestamps for publishing only changed files
35 ;; + Accept plugin functions to extend range of publishable content
37 ;; Documentation for publishing is in the manual.

52 (defvar org-publish-initial-buffer nil
53 "The buffer `org-publish' has been called from.")
55 (defvar org-publish-temp-files nil
56 "Temporary list of files to be published.")
58 ;; Here, so you find the variable right before it's used the first time:
59 (defvar org-publish-cache nil
60 "This will cache timestamps and titles for files in publishing projects.
61 Blocks could hash sha1 values here.")
63 (defgroup org-publish nil
64 "Options for publishing a set of Org-mode and related files."
65 :tag "Org Publishing"
66 :group 'org)
68 (defcustom org-publish-project-alist nil
69 "Association list to control publishing behavior.
70 Each element of the alist is a publishing 'project.' The CAR of
71 each element is a string, uniquely identifying the project. The
72 CDR of each element is in one of the following forms:
74 1. A well-formed property list with an even number of elements, alternating
75 keys and values, specifying parameters for the publishing process.
77 (:property value :property value ... )
79 2. A meta-project definition, specifying of a list of sub-projects:
81 (:components (\"project-1\" \"project-2\" ...))
83 When the CDR of an element of org-publish-project-alist is in
84 this second form, the elements of the list after :components are
85 taken to be components of the project, which group together files
86 requiring different publishing options. When you publish such a
87 project with \\[org-publish], the components all publish.
89 When a property is given a value in org-publish-project-alist, its
90 setting overrides the value of the corresponding user variable
91 \(if any) during publishing. However, options set within a file
92 override everything.
94 Most properties are optional, but some should always be set:
96 :base-directory Directory containing publishing source files
97 :base-extension Extension (without the dot!) of source files.
98 This can be a regular expression. If not given,
99 \"org\" will be used as default extension.
100 :publishing-directory Directory (possibly remote) where output
101 files will be published
103 The :exclude property may be used to prevent certain files from
104 being published. Its value may be a string or regexp matching
105 file names you don't want to be published.
107 The :include property may be used to include extra files. Its
108 value may be a list of filenames to include. The filenames are
109 considered relative to the base directory.
111 When both :include and :exclude properties are given values, the
112 exclusion step happens first.
114 One special property controls which back-end function to use for
115 publishing files in the project. This can be used to extend the
116 set of file types publishable by org-publish, as well as the set
117 of output formats.
119 :publishing-function Function to publish file. The default is
120 `org-publish-org-to-html', but other
121 values are possible. May also be a
122 list of functions, in which case
123 each function in the list is invoked
124 in turn.
126 Another property allows you to insert code that prepares a
127 project for publishing. For example, you could call GNU Make on a
128 certain makefile, to ensure published files are built up to date.
130 :preparation-function Function to be called before publishing
131 this project. This may also be a list
132 of functions.
133 :completion-function Function to be called after publishing
134 this project. This may also be a list
135 of functions.
137 Some properties control details of the Org publishing process,
138 and are equivalent to the corresponding user variables listed in
139 the right column. See the documentation for those variables to
140 learn more about their use and default values.

163 The following properties may be used to control publishing of a
164 sitemap of files or summary page for a given project.
166 :auto-sitemap Whether to publish a sitemap during
167 `org-publish-current-project' or `org-publish-all'.
168 :sitemap-filename Filename for output of sitemap. Defaults
169 to 'sitemap.org' (which becomes 'sitemap.html').
170 :sitemap-title Title of sitemap page. Defaults to name of file.
171 :sitemap-function Plugin function to use for generation of sitemap.
172 Defaults to `org-publish-org-sitemap', which
173 generates a plain list of links to all files
174 in the project.
175 :sitemap-style Can be `list' (sitemap is just an itemized list
176 of the titles of the files involved) or
177 `tree' (the directory structure of the source
178 files is reflected in the sitemap). Defaults to
179 `tree'.
180 :sitemap-sans-extension Remove extension from sitemap's
181 filenames. Useful to have cool
182 URIs (see
183 http://www.w3.org/Provider/Style/URI).
184 Defaults to nil.
186 If you create a sitemap file, adjust the sorting like this:
188 :sitemap-sort-folders Where folders should appear in the sitemap.
189 Set this to `first' (default) or `last' to
190 display folders first or last, respectively.
191 Any other value will mix files and folders.
192 :sitemap-sort-files The site map is normally sorted alphabetically.
193 You can change this behaviour setting this to
194 `chronologically', `anti-chronologically' or nil.
195 :sitemap-ignore-case Should sorting be case-sensitive? Default nil.
197 The following properties control the creation of a concept index.
199 :makeindex Create a concept index.
201 Other properties affecting publication.
203 :body-only Set this to 't' to publish only the body of the
204 documents, excluding everything outside and
205 including the <body> tags in HTML, or
206 \begin{document}..\end{document} in LaTeX."
