Modern vim plugin management: Pathogen vs Vundle
For the impatient ones: Vundle is better than pathogen, use it.
This post will explain how vim plugins work and how to easily manage your plugins with third-party tools: Pathogen or Vundle. I assume you are using a Linux distro and have git already installed. If not, consult Dr. Google for more details.
Vim plugins anatomy#
A vim plugin is simply a set of files that alter vim’s behavior or add new functionalities to it. To make this possible, by default vim looks for files in your home folder (which is
This is where you put your personalizations to vim: indentations, keybindings, etc. This post will not discuss in detail how you do your customizations. For now just know that it’s there.
You will probably want to move this file into your ~/.vim folder to be able to manage everything inside 1 folder. I will create
~/.vim/vimrc then create a symlink pointing to it. Open a terminal and type:
ln -s ~/.vim/vimrc ~/.vimrc
This should contain a bunch of subdirectories. Some examples:
Each of these directories serves a particular purpose:
colors contains colorschemes,
syntax lets you add new rules for syntax highlighting,
doc contains documentation…
A plugin will typically put its files into more than one directory here. For example, here is a plugin called tagbar, and I’ve installed it by copying its content into my
~/.vim ├── autoload │ └── tagbar.vim ├── doc │ ├── tagbar.txt │ └── tags ├── plugin │ └── tagbar.vim ├── README └── syntax └── tagbar.vim
Everything looks good. Just copy and paste the whole thing, nice and simple. How about adding a decent colorscheme? Let’s install solarized:
├── autoload │ └── togglebg.vim ├── bitmaps │ └── togglebg.png ├── colors │ └── solarized.vim ├── doc │ ├── solarized.txt │ └── tags └── README.mkd
doc/tags is already there. Ok, no problem! Let’s just copy the content of solarized’s tags file and paste it into the existing one. Now we have:
~/.vim ├── autoload │ ├── tagbar.vim │ └── togglebg.vim ├── bitmaps │ └── togglebg.png ├── colors │ └── solarized.vim ├── doc │ ├── solarized.txt │ ├── tagbar.txt │ └── tags ├── plugin │ └── tagbar.vim ├── README ├── README.mkd └── syntax └── tagbar.vim
Now what if you you decide that solarized sucks and want to get rid of it? Good luck finding which file belongs to which plugin. Oh, don’t forget the merged
doc/tags file! Now imagine you have 20-30 plugins installed (which is normal, by the way). It’s not a pretty sight now, is it?
Pathogen to the rescue!#
The legendary Tim Pope came up with a genius solution: pathogen. Now let’s install it like any regular plugin (I’ve omitted the README):
~/.vim └── autoload └── pathogen.vim
Put this at the beginning of your
Create this directory:
~/.vim/bundle. To install tagbar and solarized, just create their own directories here:
path ├── autoload │ └── pathogen.vim └── bundle ├── tagbar │ ├── autoload │ │ └── tagbar.vim │ ├── doc │ │ ├── tagbar.txt │ │ └── tags │ ├── plugin │ │ └── tagbar.vim │ ├── README │ └── syntax │ └── tagbar.vim └── vim-colors-solarized ├── autoload │ └── togglebg.vim ├── bitmaps │ └── togglebg.png ├── colors │ └── solarized.vim ├── doc │ ├── solarized.txt │ └── tags └── README.mkd
What Pathogen does is that it adds every directory inside
bundle into vim’s “runtimepath”. It means that each folder here can be considered a new
.vim folder where vim looks for appropriate configuration files. The plugins are now isolated so removing or updating them becomes trivial: just remove or update its own directory.
Pathogen + Git#
Everything goes to the cloud these days, and certainly your vim setup should as well. If you haven’t created a Github account, do it now. Create an empty repository with any name you want (mine is
.vim). Don’t commit yet. Create a file:
~/.vim/.gitignore, add these lines to its content:
.netrwhist is a local file generated by vim that is better off ignored. We also ignore bundle directory because the plugins will be included as git submodules (google git submodule for details). Remember to delete everything inside
bundle/, because we will install the plugins again with git.
Git init, commit and push to your github repo: (on the git remote add… line, replace
nhanb with your github username,
.vim with your repo name)
cd ~/.vim git init git add . git commit -m 'init' git remote add origin https://github.com/nhanb/.vim.git git push -u origin master
Everytime you edit anything in your .vim directory, remember to commit the changes and push to github:
git add . git commit -m 'some message here' git push
If you want to install a plugin, see if it has a git repo (9 out of 10 times it has a github repo). Find its git url and add to your .vim as a submodule:
cd ~/.vim git add submodule https://github.com/majutsushi/tagbar.git bundle/tagbar git add submodule https://github.com/altercation/vim-colors-solarized.git bundle/solarized git submodule update --init git submodule foreach git pull origin master
When you need to update your plugins, just run the last line to make git pull updates for all plugins.
Here’s the awesome part: when you’re using a whole new computer and want to get all your vim settings from the cloud, simply clone your github repo, make a symlink for .vimrc and pull all plugins:
cd ~ git clone https://github.com/nhanb/.vim.git .vim ln -s ~/.vim/vimrc ~/.vimrc cd .vim git submodule update --init && git submodule foreach git pull origin master
Now you must be really excited, no? Git does everything for you: upload/download, add plugins, update plugins and remove plugins… There must be some simple git command to remove a submodule, right?
NO. Sadly, no. To remove a git submodule, you’ll need to manually edit 2 git files and remove the folder by hand. See this Stackoverflow question for detailed instructions.
Vundle, the new cool kid#
This time let’s start fresh: remove all submodules and pathogen. Your bundle folder should be now empty. Clone Vundle:
git clone https://github.com/gmarik/vundle.git ~/.vim/bundle/vundle
Put this in your .vimrc (preferably at the beginning):
set nocompatible " be iMproved filetype off " required! set rtp+=~/.vim/bundle/vundle/ call vundle#rc() " let Vundle manage Vundle " required! Bundle 'gmarik/vundle' " My Bundles here: " " original repos on github Bundle 'majutsushi/tagbar' Bundle 'altercation/vim-colors-solarized' " Github repos of the user 'vim-scripts' " => can omit the username part Bundle 'L9' Bundle 'FuzzyFinder' " non github repos Bundle 'git://git.wincent.com/command-t.git' " ... filetype plugin indent on " required!
Relaunch vim, run
:BundleInstall to install the “bundles” you listed in .vimrc. When you want to update them,
:BundleUpdate. To remove a plugin, just delete its line in your .vimrc file then relaunch vim and run
:BundleClean to remove its folder inside ~/.vim/bundle/
Vundle follows Pathogen’s approach: putting plugins in their separate directories. However, it also takes care of the git stuff for us too! Note that by default it uses
git clone, not
git add submodule to add plugins. If you’re using Windows, there’s Vundle for Windows too, though I’ve never tried it.
That’s it, happy coding! Feel free to leave your comments if there’s anything wrong/unclear here.
