This commit shows how to convert luarocks packages into (neo)vim ones. The advantage for neovim lua plugins to register their rockspec (aka package definition) is that the plugin can express its dependencies and a few metadata through it.

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.
