+**UPDATE** I have created a [[page|tips/follow_wikilinks_from_inside_vim]] in
+the tips section about the plugin, how to get it, install it and use it. Check
+that out. --[[jerojasro]]
+
I wrote a vim function to help me navigate the wiki when I'm editing it. It extends the 'gf' (goto file) functionality. Once installed, you place the cursor on a wiki page name and press 'gf' (without the quotes); if the file exists, it gets loaded.
This function takes into account the ikiwiki linking rules when deciding which file to go to.
>> repo, do you see any alternative?

-To enable this functionality, paste the code below in your `.vim/ftplugin/ikiwiki.vim` file
- " returns the directory which can be considered the root of the wiki the
- " current buffer belongs to, or an empty string if we are not inside an
- " ikiwiki wiki
- "
- " NOTE: the root of the wiki is considered the first directory that contains a
- " .ikiwiki folder, except $HOME/.ikiwiki (the usual ikiwiki libdir)
- "
- " if you can think of a better heuristic to get ikiwiki's root, let me know!
- function! GetWikiRootDir()
- let check_str = '%:p:h'
- let pos_wiki_root = expand(check_str)
- while pos_wiki_root != '/'
- if isdirectory(pos_wiki_root . '/.ikiwiki') && pos_wiki_root != $HOME
- return pos_wiki_root
- endif
- let check_str = check_str . ':h'
- let pos_wiki_root = expand(check_str)
- endwhile
- if isdirectory('/.ikiwiki')
- return '/'
- endif
- return ''
- endfunction
-
- " This function searches for a .mdwn file (<a:name>.mdwn) using the ikiwiki
- " WikiLink rules and returns its full path.
- "
- " The rules are the following
- "
- " if the filename starts with '/', use as base dir the root directory of the
- " wiki
- "
- " if not:
- "
- " try first ./<bufname>/<a:name>.mdwn
- " then for ./<a:name>.mdwn
- " then for <root_of_wiki>/<a:name>.mdwn
- "
- " return the first one that exists
- "
- " the base path (. above) is the directory that contains the current buffer
- "
- function! FileForWikiLink(name)
- let target_fname=a:name . ".mdwn"
- let wikiroot_dir = GetWikiRootDir()
- if match(target_fname, '^/') >= 0
- return wikiroot_dir . target_fname
- endif
- let subdir_file = expand('%:p:r') . "/" . target_fname
- let currdir_file = expand('%:p:h') . "/" . target_fname
- let wikiroot_file = wikiroot_dir . "/" . target_fname
- if filewritable(subdir_file)
- return subdir_file
- endif
- if filewritable(currdir_file)
- return currdir_file
- endif
- if filewritable(wikiroot_file)
- return wikiroot_file
- endif
- return a:name
- endfunction

- setlocal includeexpr=FileForWikiLink(v:fname)
+well. I've rewritten the whole thing, to take into account:
+
+ * file matching ignoring case (MyPage matches mypage.mdwn)
+ * checking all the way down (up) to the root of the wiki (if there is a link `\[[foo]]` on `a/b/page`),
+ try `a/b/page/foo`, then `a/b/foo`, and so on, up to `foo`
+ * the alternate name for a page: when looking for the file for `\[[foo]]`, try both `foo.mdwn` and `foo/index.mdwn`
+
+you can find the file [here](http://git.devnull.li/cgi-bin/gitweb.cgi?p=vim-jerojasro.git;a=blob;f=.vim/ftplugin/ikiwiki_nav.vim;hb=HEAD). To use it, place it in `$HOME/.vim/ftplugin`. After that, hitting `<CR>` (Enter) in normal mode over a wikilink will take you to that page, if it exists.
+
+the plugin has, as of now, two problems:
+
+ * doesn't work with wikilinks that take more than one line (though this isn't really that bad)
+ * it assumes that the root of the wiki is the first directory down the filesystem hierarchy that
+ has a `.ikiwiki` folder on it. If your copy of the wiki doesn't have it, you must create it for
+ the plugin to work

+> Interesting. I was at one point looking at "potwiki.vim", which implements a local wiki and follows CamelCase links, creating new files where necessary etc., to see if it could be adapted for ikiwiki (See [[tips/vim syntax highlighting/discussion]]). I didn't get anywhere. -- [[Jon]]
