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

  54   :group 'org)
  55
  56 (defcustom org-publish-project-alist nil
  57   "Association list to control publishing behavior.
  58 Each element of the alist is a publishing 'project.'  The CAR of
  59 each element is a string, uniquely identifying the project.  The
  60 CDR of each element is in one of the following forms:
  61
  62   (:property value :property value ... )
  63
  64 OR,
  65
  66   (:components (\"project-1\" \"project-2\" ...))
  67
  68 When the CDR of an element of org-publish-project-alist is in
  69 this second form, the elements of the list after :components are
  70 taken to be components of the project, which group together files
  71 requiring different publishing options.  When you publish such a
  72 project with \\[org-publish], the components all publish.
  73
  74 When a property is given a value in org-publish-project-alist, its
  75 setting overrides the value of the corresponding user variable
  76 \(if any) during publishing.  However, options set within a file
  77 override everything.
  78
  79 Most properties are optional, but some should always be set:
  80
  81   :base-directory        Directory containing publishing source files
  82   :base-extension        Extension (without the dot!) of source files.
  83                          This can be a regular expression.
  84   :publishing-directory  Directory (possibly remote) where output
  85                          files will be published
  86
  87 The :exclude property may be used to prevent certain files from
  88 being published.  Its value may be a string or regexp matching
  89 file names you don't want to be published.
  90
  91 The :include property may be used to include extra files.  Its
  92 value may be a list of filenames to include. The filenames are
  93 considered relative to the base directory.
  94
  95 When both :include and :exclude properties are given values, the
  96 exclusion step happens first.
  97
  98 One special property controls which back-end function to use for
  99 publishing files in the project.  This can be used to extend the
 100 set of file types publishable by org-publish, as well as the set
 101 of output formats.
 102
 103   :publishing-function     Function to publish file.  The default is
 104                            `org-publish-org-to-html', but other
 105                            values are possible.  May also be a
 106                            list of functions, in which case
 107                            each function in the list is invoked
 108                            in turn.
 109
 110 Another property allows you to insert code that prepares a
 111 project for publishing.  For example, you could call GNU Make on a
 112 certain makefile, to ensure published files are built up to date.
 113
 114   :preparation-function   Function to be called before publishing
 115                           this project.
 116   :completion-function    Function to be called after publishing
 117                           this project.
 118
 119 Some properties control details of the Org publishing process,
 120 and are equivalent to the corresponding user variables listed in
 121 the right column.  See the documentation for those variables to
 122 learn more about their use and default values.

 147 The following properties may be used to control publishing of an
 148 index of files or summary page for a given project.
 149
 150   :auto-index            Whether to publish an index during
 151                          `org-publish-current-project' or `org-publish-all'.
 152   :index-filename        Filename for output of index.  Defaults
 153                          to 'sitemap.org' (which becomes 'sitemap.html').
 154   :index-title           Title of index page.  Defaults to name of file.
 155   :index-function        Plugin function to use for generation of index.
 156                          Defaults to `org-publish-org-index', which
 157                          generates a plain list of links to all files
 158                          in the project.
 159   :index-style           Can be `list' (index is just an itemized list
 160                          of the titles of the files involved) or
 161                          `tree' (the directory structure of the source
 162                          files is reflected in the index).  Defaults to
 163                          `tree'."
