poor man's plugin downloader for vim

Simple, slim, mini wrapper around git clone, git pull and tpope's pathogen.vim

What is this?

It's a piece of vimscript which:

• allows you to keep your list of plugins in vimrc

• on vim startup, downloads any new plugins and activates them with pathogen (aka "Poor man's package manager")

• provides a :UpdatePlugins command

How does it work?

• run git clone on vim startup for any missing plugins
• run git pull for each plugin when :UpdatePlugins is executed

Usage

Adding snippets in your vimrc

1. copy the snippet (below) in your vimrc

2. add any plugins you want (make sure you don't remove pathogen from the list, duh..), like so

Pl 'tpope/vim-sensible'  'tpope/vim-commentary' 'tpope/vim-eunuch'
Pl 'tpope/vim-obsession' 'tpope/vim-tbone'      'tpope/vim-unimpaired'
Pl 'tpope/vim-git'       'tpope/vim-markdown'   'tpope/vim-fugitive'

3. restart vim - missing plugins will be fetched from github

Updating plugins

1. run :UpdatePlugins when you feel like it

The snippet

let g:plugin_dir = expand('~/.vim/bundle', ':p')
let g:plugin_hash = {}
let g:pathogen_blacklist = []

" Poor man's plugin downloader {{{
if !isdirectory(g:plugin_dir) | call mkdir(g:plugin_dir, "p") | endif

function! DownloadPluginIfMissing(plugin) abort
  let output_dir = g:plugin_dir . '/' . fnamemodify(a:plugin, ":t")
  if isdirectory(output_dir) || !executable('git')
    return
  endif
  let command = printf("git clone -q %s %s", "https://github.com/" . a:plugin . '.git', output_dir)
  echo "DownloadPluginIfMissing: " . command | echo system(command)
  silent! execute 'helptags ' . output_dir . '/doc'
endfunction

function! UpdatePlugin(plugin) abort
  let output_dir = g:plugin_dir . '/' . fnamemodify(a:plugin, ":t")
  if !isdirectory(output_dir) || !executable('git')
    return
  endif
  let command = printf("cd %s && git pull -q", output_dir)
  echo "UpdatePlugin: " . command | echo system(command)
endfunction

function! Pl(...) abort
  for plugin in map(copy(a:000), 'substitute(v:val, ''''''\|"'', "", "g")')
    let g:plugin_hash[ fnamemodify(plugin, ':t') ] = 1
    call DownloadPluginIfMissing(plugin)
  endfor
endfunction

" }}}

Pl 'tpope/vim-git'       'tpope/vim-markdown'   'tpope/vim-fugitive'

" run pathogen
Pl 'tpope/vim-pathogen'
execute "source " . g:plugin_dir . '/vim-pathogen/autoload/pathogen.vim'
let g:pathogen_blacklist = filter(map(split(glob(g:plugin_dir . '/*', 1), "\n"),'fnamemodify(v:val,":t")'), '!has_key(g:plugin_hash, v:val)')
execute pathogen#infect(g:plugin_dir . '/{}')
