USAGE EXAMPLE
=============
Install Vim like this eg using nixos option environment.systemPackages which will provide
vim-with-plugins in PATH:
vim_configurable.customize {
name = "vim-with-plugins"; # optional
# add custom .vimrc lines like this:
vimrcConfig.customRC = ''
set hidden
'';
# store your plugins in Vim packages
vimrcConfig.packages.myVimPackage = with pkgs.vimPlugins; {
# loaded on launch
start = [ youcompleteme fugitive ];
# manually loadable by calling `:packadd $plugin-name`
opt = [ phpCompletion elm-vim ];
# To automatically load a plugin when opening a filetype, add vimrc lines like:
# autocmd FileType php :packadd phpCompletion
};
};
WHAT IS A VIM PLUGIN?
=====================
Typical plugin files:
plugin/P1.vim
autoload/P1.vim
ftplugin/xyz.vim
doc/plugin-documentation.txt (traditional documentation)
README(.md) (nowadays thanks to github)
Vim offers the :h rtp setting which works for most plugins. Thus adding
this to your .vimrc should make most plugins work:
set rtp+=~/.nix-profile/share/vim-plugins/youcompleteme
" or for p in ["youcompleteme"] | exec 'set rtp+=~/.nix-profile/share/vim-plugins/'.p | endfor
Learn about about plugin Vim plugin mm managers at
http://vim-wiki.mawercer.de/wiki/topic/vim%20plugin%20managment.html.
The documentation can be accessed by Vim's :help command if it was tagged.
See vimHelpTags sample code below.
CONTRIBUTING AND CUSTOMIZING
============================
The example file pkgs/applications/editors/vim/plugins/default.nix provides
both:
* manually mantained plugins
* plugins created by VAM's nix#ExportPluginsForNix implementation
I highly recommend to lookup vim plugin attribute names at the [vim-pi] project
which is a database containing all plugins from
vim.org and quite a lot of found at github and similar sources. vim-pi's documented purpose
is to associate vim.org script ids to human readable names so that dependencies
can be describe easily.
How to find a name?
* http://vam.mawercer.de/ or VAM's
* grep vim-pi
* use VAM's completion or :AddonsInfo command
It might happen than a plugin is not known by vim-pi yet. We encourage you to
contribute to vim-pi so that plugins can be updated automatically.
CREATING DERIVATIONS AUTOMATICALLY BY PLUGIN NAME
==================================================
Most convenient is to use a ~/.vim-scripts file putting a plugin name into each line
as documented by [VAM]'s README.md
It is the same format you pass to vimrcConfig.vam.pluginDictionaries from the
usage example above.
Then create a temp vim file and insert:
let opts = {}
let opts.path_to_nixpkgs = '/etc/nixos/nixpkgs'
let opts.cache_file = '/tmp/export-vim-plugin-for-nix-cache-file'
let opts.plugin_dictionaries = map(readfile("vim-plugins"), 'eval(v:val)')
" add more files
" let opts.plugin_dictionaries += map(.. other file )
call nix#ExportPluginsForNix(opts)
Then ":source %" it.
nix#ExportPluginsForNix is provided by ./vim2nix
A buffer will open containing the plugin derivation lines as well list
fitting the vimrcConfig.vam.pluginDictionaries option.
Thus the most simple usage would be:
vim_with_plugins =
let vim = vim_configurable;
inherit (vimUtil.override {inherit vim}) rtpPath addRtp buildVimPlugin vimHelpTags;
vimPlugins = [
# the derivation list from the buffer created by nix#ExportPluginsForNix
# don't set which will default to pkgs.vimPlugins
];
in vim.customize {
name = "vim-with-plugins";
vimrcConfig.customRC = '' .. '';
vimrcConfig.vam.knownPlugins = vimPlugins;
vimrcConfig.vam.pluginDictionaries = [
# the plugin list form ~/.vim-scripts turned into nix format added to
# the buffer created by the nix#ExportPluginsForNix
];
}
vim_with_plugins can be installed like any other application within Nix.
