ikiwiki - a wiki compiler


ikiwiki [options] source destination

ikiwiki --setup setupfile [options]


ikiwiki is a wiki compiler. It builds static HTML pages for a wiki, from source in the Markdown language (or others), and writes it out to destination.

Note that most options can be shortened to single letters, boolean flags such as --verbose can be negated with --no-verbose, and options such as --verbose can also be spelled like -verbose.


These options control the mode that ikiwiki operates in.

  • --refresh

    Refresh the wiki, updating any changed pages. This is the default behavior if no other mode action is specified (but note that --setup is a mode action, and has different default behavior).

  • --rebuild

    Force a rebuild of all pages.

  • --setup setupfile

    Load options from the given setup file. If no other mode action is specified, generate wrappers and rebuild the wiki, as if --rebuild --wrappers were used. If you only want to build any changed pages, you can use --refresh with --setup.

  • --changesetup setupfile

    Reads the setup file, adds any configuration changes specified by other options, and writes the new configuration back to the setup file. Also updates any configured wrappers. In this mode, the wiki is not fully rebuilt, unless you also add --rebuild.

    Example, to enable some plugins:

    ikiwiki --changesetup ~/ikiwiki.setup --plugin goodstuff --plugin calendar

  • --dumpsetup setupfile

    Causes ikiwiki to write to the specified setup file, dumping out its current configuration.

  • --wrappers

    If used with --setup --refresh, this makes it also update any configured wrappers.

  • --clean

    This makes ikiwiki clean up by removing any files it generated in the destination directory, as well as any configured wrappers, and the .ikiwiki state directory. This is mostly useful if you're running ikiwiki in a Makefile to build documentation and want a corresponding clean target.

  • --cgi

    Enable CGI mode. In cgi mode ikiwiki runs as a cgi script, and supports editing pages, signing in, and registration.

    To use ikiwiki as a CGI program you need to use --wrapper or --setup to generate a wrapper. The wrapper will generally need to run suid 6755 to the user who owns the source and destination directories.

  • --wrapper [file]

    Generate a wrapper binary that is hardcoded to do action specified by the other options, using the specified input files and destination directory. The filename to use for the wrapper is optional.

    The wrapper is designed to be safely made suid and be run by untrusted users, as a post-commit hook, or as a CGI.

    Note that the generated wrapper will ignore all command line parameters.

  • --aggregate

    If the aggregate plugin is enabled, this makes ikiwiki poll configured feeds and save new posts to the srcdir.

    Note that to rebuild previously aggregated posts, use the --rebuild option along with this one. --rebuild will also force feeds to be polled even if they were polled recently.

  • --render file

    Renders a single file, outputting the resulting html. Does not save state, so this cannot be used for building whole wikis, but it is useful for previewing an edited file at the command line. Generally used in conjunction with --setup to load in a wiki's setup:

    ikiwiki --setup ~/ikiwiki.setup --render foo.mdwn

  • --post-commit

    Run in post-commit mode, the same as if called by a post-commit hook. This is probably only useful when using ikiwiki with a web server on one host and a repository on another, to allow the repository's real post-commit hook to ssh to the web server host and manually run ikiwiki to update the web site.

  • --version

    Print ikiwiki's version number.


These options configure the wiki. Note that plugins can add additional configuration options of their own. All of these options and more besides can also be configured using a setup file.

  • --wikiname name

    The name of the wiki, default is "wiki".

  • --templatedir dir

    Specify the directory that templates are stored in. Default is /usr/share/ikiwiki/templates, or another location as configured at build time. If the templatedir is changed, missing templates will still be searched for in the default location as a fallback. Templates can also be placed in the "templates/" subdirectory of the srcdir.

    Note that if you choose to copy and modify ikiwiki's templates, you will need to be careful to keep them up to date when upgrading to new versions of ikiwiki. Old versions of templates do not always work with new ikiwiki versions.

  • --underlaydir dir

    Specify the directory that is used to underlay the source directory. Source files will be taken from here unless overridden by a file in the source directory. Default is /usr/share/ikiwiki/basewiki or another location as configured at build time.

  • --wrappermode mode

    Specify a mode to chmod the wrapper to after creating it.

  • --wrappergroup group

    Specify what unix group the wrapper should be owned by. This can be useful if the wrapper needs to be owned by a group other than the default. For example, if a project has a repository with multiple committers with access controlled by a group, it makes sense for the ikiwiki wrappers to run setgid to that group.

  • --rcs=svn|git|.., --no-rcs

    Enable or disable use of a revision control system.

    The source directory will be assumed to be a working copy, or clone, or whatever the revision control system you select uses.

    In CGI mode, with a revision control system enabled, pages edited via the web will be committed.

    No revision control is enabled by default.

  • --svnrepo /svn/wiki

    Specify the location of the svn repository for the wiki.

  • --svnpath trunk

    Specify the path inside your svn repository where the wiki is located. This defaults to trunk; change it if your wiki is at some other path inside the repository. If your wiki is rooted at the top of the repository, set svnpath to "".

  • --rss, --norss

    If rss is set, ikiwiki will default to generating RSS feeds for pages that inline a blog.

  • --allowrss

    If allowrss is set, and rss is not set, ikiwiki will not default to generating RSS feeds, but setting rss=yes in the inline directive can override this default and generate a feed.

  • --atom, --noatom

    If atom is set, ikiwiki will default to generating Atom feeds for pages that inline a blog.

  • --allowatom

    If allowatom is set, and rss is not set, ikiwiki will not default to generating Atom feeds, but setting atom=yes in the inline directive can override this default and generate a feed.

  • --pingurl URL

    Set this to the URL of an XML-RPC service to ping when an RSS feed is updated. For example, to ping Technorati, use the URL

    This parameter can be specified multiple times to specify more than one URL to ping.

  • --url URL

    Specifies the URL to the wiki. This is a required parameter in CGI mode.

  • --cgiurl

    Specifies the URL to the ikiwiki CGI script wrapper. Required when building the wiki for links to the cgi script to be generated.

  • --historyurl URL

    Specifies the URL to link to for page history browsing. In the URL, "[[file]]" is replaced with the file to browse. It's common to use ?ViewVC for this.

  • --adminemail

    Specifies the email address that ikiwiki should use for sending email.

  • --diffurl URL

    Specifies the URL to link to for a diff of changes to a page. In the URL, "[[file]]" is replaced with the file to browse, "[[r1]]" is the old revision of the page, and "[[r2]]" is the new revision. It's common to use ?ViewVC for this.

  • --exclude regexp

    Specifies a rexexp of source files to exclude from processing. May be specified multiple times to add to exclude list.

  • --include regexp

    Specifies a rexexp of source files, that would normally be excluded, but that you wish to include in processing. May be specified multiple times to add to include list.

  • --adminuser name

    Specifies a username of a user (or, if openid is enabled, an openid) who has the powers of a wiki admin. Currently allows locking of any page, and banning users, as well as powers granted by enabled plugins (such as moderating comments and websetup. May be specified multiple times for multiple admins.

    For an openid user specify the full URL of the login, including "http://".

  • --plugin name

    Enables the use of the specified plugin in the wiki. Note that plugin names are case sensitive.

  • --disable-plugin name

    Disables use of a plugin. For example "--disable-plugin htmlscrubber" to do away with HTML sanitization.

  • --libdir directory

    Makes ikiwiki look in the specified directory first, before the regular locations when loading library files and plugins. For example, if you set libdir to "/home/you/.ikiwiki/", you can install a plugin as "/home/you/.ikiwiki/IkiWiki/Plugin/".

  • --discussion, --no-discussion

    Enables or disables "Discussion" links from being added to the header of every page. The links are enabled by default.

  • --numbacklinks n

    Controls how many backlinks should be displayed at the bottom of a page. Excess backlinks will be hidden in a popup. Default is 10. Set to 0 to disable this feature.

  • --userdir subdir

    Optionally, allows links to users of the wiki to link to pages inside a subdirectory of the wiki. The default is to link to pages in the toplevel directory of the wiki.

  • --htmlext html

    Configures the extension used for generated html files. Default is "html".

  • --timeformat format

    Specify how to display the time or date. The format string is passed to the strftime(3) function.

  • --verbose, --no-verbose

    Be verbose about what is being done.

  • --syslog, --no-syslog

    Log to syslog(3).

  • --usedirs, --no-usedirs

    Toggle creating output files named page/index.html (default) instead of page.html.

  • --prefix-directives, --no-prefix-directives

    Toggle new '!'-prefixed syntax for preprocessor directives. ikiwiki currently defaults to --prefix-directives.

  • --w3mmode, --no-w3mmode

    Enable w3mmode, which allows w3m to use ikiwiki as a local CGI script, without a web server.

  • --sslcookie

    Only send cookies over an SSL connection. This should prevent them being intercepted. If you enable this option then you must run at least the CGI portion of ikiwiki over SSL.

  • --gettime, --no-gettime

    Extract creation and modification times for each new page from the the revision control's log. This is done automatically when building a wiki for the first time, so you normally do not need to use this option.

  • --set var=value

    This allows setting an arbitrary configuration variable, the same as if it were set via a setup file. Since most commonly used options can be configured using command-line switches, you will rarely need to use this.

  • --set-yaml var=value

    This is like --set, but it allows setting configuration variables that use complex data structures, by passing in a YAML document.


  • ikiwiki --setup my.setup

    Completely (re)build the wiki using the specified setup file.

  • ikiwiki --setup my.setup --refresh

    Refresh the wiki, using settings from my.setup, and avoid rebuilding any pages that have not changed. This is faster.

  • ikiwiki --setup my.setup --refresh --wrappers

    Refresh the wiki, including regenerating all wrapper programs, but do not rebuild all pages. Useful if you have changed something in the setup file that does not need a full wiki rebuild to update all pages, but that you want to immediately take effect.

  • ikiwiki --rebuild srcdir destdir

    Use srcdir as source and build HTML in destdir, without using a setup file.

  • ikiwiki srcdir destdir

    Use srcdir as source to update changed pages' HTML in destdir, without using a setup file.


  • CC

    This controls what C compiler is used to build wrappers. Default is 'cc'.


    This can be used to pass options to the C compiler when building wrappers.
