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
ikiwiki/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


These options control the mode that ikiwiki operates in.

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).

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

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

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.

If the plugins/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

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.

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

--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

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.

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 http://rpc.technorati.com/rpc/ping

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

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

--cgiurl http://example.org/ikiwiki.cgi
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 [email protected]
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

--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|plugins/moderatedcomments]] and plugins/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 foo.pm plugin as

--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

--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.

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

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.



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

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