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";
|
|
|
|
# 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
|
|
};
|
|
|
|
# plugins can also be managed by VAM
|
|
vimrcConfig.vam.knownPlugins = pkgs.vimPlugins; # optional
|
|
vimrcConfig.vam.pluginDictionaries = [
|
|
# load always
|
|
{ name = "youcompleteme"; }
|
|
{ names = ["youcompleteme" "foo"]; }
|
|
|
|
# only load when opening a .php file
|
|
{ name = "phpCompletion"; ft_regex = "^php\$"; }
|
|
{ name = "phpCompletion"; filename_regex = "^.php\$"; }
|
|
|
|
# provide plugin which can be loaded manually:
|
|
{ name = "phpCompletion"; tag = "lazy"; }
|
|
|
|
# full documentation at github.com/MarcWeber/vim-addon-manager
|
|
];
|
|
|
|
# there is a pathogen implementation as well, but its startup is slower and [VAM] has more feature
|
|
# vimrcConfig.pathogen.knownPlugins = vimPlugins; # optional
|
|
# vimrcConfig.pathogen.pluginNames = ["vim-addon-nix"];
|
|
};

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
|
|
|
|
which is what the [VAM]/pathogen solutions above basically do.
|
|
|
|
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/misc/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 DERVITATIONS 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.
