# User's Guide to Vim Plugins/Addons/Bundles/Scripts in Nixpkgs
|
|
|
|
You'll get a vim(-your-suffix) in PATH also loading the plugins you want.
|
|
Loading can be deferred; see examples.
|
|
|
|
Vim packages, VAM (=vim-addon-manager) and Pathogen are supported to load
|
|
packages.
|
|
|
|
## Custom configuration
|
|
|
|
Adding custom .vimrc lines can be done using the following code:
|
|
|
|
```
|
|
vim_configurable.customize {
|
|
name = "vim-with-plugins";
|
|
|
|
vimrcConfig.customRC = ''
|
|
set hidden
|
|
'';
|
|
}
|
|
```
|
|
|
|
## Vim packages
|
|
|
|
To store you plugins in Vim packages the following example can be used:
|
|
|
|
```
|
|
vim_configurable.customize {
|
|
vimrcConfig.packages.myVimPackage = with pkgs.vimPlugins; {
|
|
# loaded on launch
|
|
start = [ youcompleteme fugitive ];
|
|
# manually loadable by calling `:packadd $plugin-name`
|
|
opt = [ phpCompletion elm-vim ];
|
|
# To automatically load a plugin when opening a filetype, add vimrc lines like:
|
|
# autocmd FileType php :packadd phpCompletion
|
|
}
|
|
};
|
|
```
|
|
|
|
## VAM
|
|
|
|
### dependencies by Vim plugins
|
|
|
|
VAM introduced .json files supporting dependencies without versioning
|
|
assuming that "using latest version" is ok most of the time.
|
|
|
|
### Example
|
|
|
|
First create a vim-scripts file having one plugin name per line. Example:
|
|
|
|
"tlib"
|
|
{'name': 'vim-addon-sql'}
|
|
{'filetype_regex': '\%(vim)$', 'names': ['reload', 'vim-dev-plugin']}
|
|
|
|
Such vim-scripts file can be read by VAM as well like this:
|
|
|
|
call vam#Scripts(expand('~/.vim-scripts'), {})
|
|
|
|
Create a default.nix file:
|
|
|
|
{ nixpkgs ? import <nixpkgs> {}, compiler ? "ghc7102" }:
|
|
nixpkgs.vim_configurable.customize { name = "vim"; vimrcConfig.vam.pluginDictionaries = [ "vim-addon-vim2nix" ]; }
|
|
|
|
Create a generate.vim file:
|
|
|
|
ActivateAddons vim-addon-vim2nix
|
|
let vim_scripts = "vim-scripts"
|
|
call nix#ExportPluginsForNix({
|
|
\ 'path_to_nixpkgs': eval('{"'.substitute(substitute(substitute($NIX_PATH, ':', ',', 'g'), '=',':', 'g'), '\([:,]\)', '"\1"',"g").'"}')["nixpkgs"],
|
|
\ 'cache_file': '/tmp/vim2nix-cache',
|
|
\ 'try_catch': 0,
|
|
\ 'plugin_dictionaries': ["vim-addon-manager"]+map(readfile(vim_scripts), 'eval(v:val)')
|
|
\ })
|
|
|
|
Then run
|
|
|
|
nix-shell -p vimUtils.vim_with_vim2nix --command "vim -c 'source generate.vim'"
|
|
|
|
You should get a Vim buffer with the nix derivations (output1) and vam.pluginDictionaries (output2).
|
|
You can add your vim to your system's configuration file like this and start it by "vim-my":
|
|
|
|
my-vim =
|
|
let plugins = let inherit (vimUtils) buildVimPluginFrom2Nix; in {
|
|
copy paste output1 here
|
|
}; in vim_configurable.customize {
|
|
name = "vim-my";
|
|
|
|
vimrcConfig.vam.knownPlugins = plugins; # optional
|
|
vimrcConfig.vam.pluginDictionaries = [
|
|
copy paste output2 here
|
|
];
|
|
|
|
# Pathogen would be
|
|
# vimrcConfig.pathogen.knownPlugins = plugins; # plugins
|
|
# vimrcConfig.pathogen.pluginNames = ["tlib"];
|
|
};
|
|
|
|
|
|
Sample output1:
|
|
|
|
"reload" = buildVimPluginFrom2Nix { # created by nix#NixDerivation
|
|
name = "reload";
|
|
src = fetchgit {
|
|
url = "git://github.com/xolox/vim-reload";
|
|
rev = "0a601a668727f5b675cb1ddc19f6861f3f7ab9e1";
|
|
sha256 = "0vb832l9yxj919f5hfg6qj6bn9ni57gnjd3bj7zpq7d4iv2s4wdh";
|
|
};
|
|
dependencies = ["nim-misc"];
|
|
|
|
};
|
|
[...]
|
|
|
|
Sample output2:
|
|
|
|
[
|
|
''vim-addon-manager''
|
|
''tlib''
|
|
{ "name" = ''vim-addon-sql''; }
|
|
{ "filetype_regex" = ''\%(vim)$$''; "names" = [ ''reload'' ''vim-dev-plugin'' ]; }
|
|
]
|
|
|
|
|
|
## Important repositories
|
|
|
|
- [vim-pi](https://bitbucket.org/vimcommunity/vim-pi) is a plugin repository
|
|
from VAM plugin manager meant to be used by others as well used by
|
|
|
|
- [vim2nix](http://github.com/MarcWeber/vim-addon-vim2nix) which generates the
|
|
.nix code
|
|
