Allows you to move to previous/next N class, function or method
or visually select the next/previous N class, function or method
or comment (or toggle) out the next/previous N class, function or method.
As this is a "file-type plugin", it currently supports both Python and Ruby.

Installation couldn't be easier: drop the ftplugin file in your vim ftplugin directory. For example, if you are using Python, this would be something like:
I would highly recommend you use something like Pathogen though, it makes dealing with VIM plugins way easier.
After trying other plugins that were supposed to achieve this objective (and fail) I decided to write it on my own.
No need to have VIM compiled with Python or Ruby support since this plugin uses pure VIM syntax.
There are a couple of routes you can take: with or without default mappings.
If you want to define your own mappings then no need to do anything else other than know the actual plugin calls (listed below).
If you want the default mappings (also listed below) you need to add this to your vimrc:
let g:chapa_default_mappings = 1
You can also make the repeat actions for the plugin optional. If the above variable is set but you don't like the repeat mappings, set the following in your vimrc:
let g:chapa_no_repeat_mappings = 1
You can map those callables to anything you want, but below is how the defaults are mapped:
" Repeat Mappings nmap <buffer> <C-h> <Plug>ChapaOppositeRepeat nmap <buffer> <C-l> <Plug>ChapaRepeat " Function Movement nmap <buffer> fnf <Plug>ChapaNextFunction nmap <buffer> fif <Plug>ChapaInFunction nmap <buffer> fpf <Plug>ChapaPreviousFunction " Class Movement nmap <buffer> fnc <Plug>ChapaNextClass nmap <buffer> fic <Plug>ChapaInClass nmap <buffer> fpc <Plug>ChapaPreviousClass " Method Movement nmap <buffer> fnm <Plug>ChapaNextMethod nmap <buffer> fim <Plug>ChapaInMethod nmap <buffer> fpm <Plug>ChapaPreviousMethod " Class Visual Select nmap <buffer> vnc <Plug>ChapaVisualNextClass nmap <buffer> vic <Plug>ChapaVisualThisClass nmap <buffer> vpc <Plug>ChapaVisualPreviousClass " Method Visual Select nmap <buffer> vnm <Plug>ChapaVisualNextMethod nmap <buffer> vim <Plug>ChapaVisualThisMethod nmap <buffer> vpm <Plug>ChapaVisualPreviousMethod " Function Visual Select nmap <buffer> vnf <Plug>ChapaVisualNextFunction nmap <buffer> vif <Plug>ChapaVisualThisFunction nmap <buffer> vpf <Plug>ChapaVisualPreviousFunction " Comment Class nmap <buffer> cic <Plug>ChapaCommentThisClass nmap <buffer> cnc <Plug>ChapaCommentNextClass nmap <buffer> cpc <Plug>ChapaCommentPreviousClass " Comment Method nmap <buffer> cim <Plug>ChapaCommentThisMethod nmap <buffer> cnm <Plug>ChapaCommentNextMethod nmap <buffer> cpm <Plug>ChapaCommentPreviousMethod " Comment Function nmap <buffer> cif <Plug>ChapaCommentThisFunction nmap <buffer> cnf <Plug>ChapaCommentNextFunction nmap <buffer> cpf <Plug>ChapaCommentPreviousFunction " Folding Method nmap <buffer> zim <Plug>ChapaFoldThisMethod nmap <buffer> znm <Plug>ChapaFoldNextMethod nmap <buffer> zpm <Plug>ChapaFoldPreviousMethod " Folding Class nmap <buffer> zic <Plug>ChapaFoldThisClass nmap <buffer> znc <Plug>ChapaFoldNextClass nmap <buffer> zpc <Plug>ChapaFoldPreviousClass " Folding Function nmap <buffer> zif <Plug>ChapaFoldThisFunction nmap <buffer> znf <Plug>ChapaFoldNextFunction nmap <buffer> zpf <Plug>ChapaFoldPreviousFunction
Since these should only be defined for buffers of the supported filetypes, if
you don't enable the default mappings you'll want to define your own through e.g.
~/.vim/after/ftplugin/python.vim or with
If the requested search (function, class or method) is not found, the call simply returns and nothing should happen. However, there is an error message that should display by default, explaining what it was supposed to search and in what direction.
You can disable this by adding a chapa-specific variable in your vimrc:
let g:chapa_messages = 0
You can also add a "count" to repeat the match N times. So if you want to go to the 3rd previous class you would (with the mappings above) do something like:
The same applies for visual selections. If you want to visually select the 3rd next method, you would do it like:
You can also toggle comments of a given class, method or function. To comment the next class:
If the class is already commented, the command above will remove the comments.
If you are moving around, the plugin allows you to repeat the forward or reverse (opposite to the original) move. For example, if you searched for the next function like:
<C-l> repeats that same command for you and moves you in the same
direction. If you want to go in the opposite movement, then
<C-h> is your
