[[meta title="Installing third party plugins"]] Most ikiwiki plugins are perl modules and should be installed somewhere in the perl module search path. See the @INC list at the end of the output of `perl -V` for a list of the directories in that path. All plugins are in the IkiWiki::Plugin namespace, so they go in a IkiWiki/Plugin subdirectory inside the perl search path. For example, if your perl looks in `/usr/local/lib/site_perl` for modules, you can locally install ikiwiki plugins to `/usr/local/lib/site_perl/IkiWiki/Plugin` You can use the `libdir` configuration option to add a directory to the search path. For example, if you set `libdir` to `/home/you/.ikiwiki/`, then ikiwiki will look for plugins in `/home/you/.ikiwiki/IkiWiki/Plugin`. Ikiwiki also supports plugins that are external programs. These are typically written in some other language than perl. Ikiwiki searches for these in `/usr/lib/ikiwiki/plugins` by default. If `libdir` is set, it will also look under that directory, for example in `/home/you/.ikiwiki/plugins`. Note that this type of plugin has to be executable for ikiwiki to use it.
