1 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.
3 This function takes into account the ikiwiki linking rules when deciding which file to go to.
5 > 'gf' gets in the way when there are directories with the same name of a wiki page. The

7 > if there is no match ascend the dir. hierarchy and start over, until we reach the root of

16 let me know what you think
18 To enable this functionality, paste the code below in your `.vim/ftplugin/ikiwiki.vim` file
20 " returns the directory which can be considered the root of the wiki the
21 " current buffer belongs to, or an empty string if we are not inside an
24 " NOTE: the root of the wiki is considered the first directory that contains a
25 " .ikiwiki folder, except $HOME/.ikiwiki (the usual ikiwiki libdir)
27 " if you can think of a better heuristic to get ikiwiki's root, let me know!
