How can I customize Vim for web development and programming?
Everyone else has excellent advice, I thought I'd fill in with some of the basics:
1. GVim for vim outside the console, and how to install it
You asked whether vim can only be run from the console. GVim (GUI-Vim) is the standalone version. From your screenshot, it looks like you're using Ubuntu, you can find gvim in the Software Centre and install it from there. Alternatively you can sudo apt-get install gvim
from a terminal.
2. Creating a .vimrc config file
It looks like, by default, vim/gvim doesn't create a .vimrc
for you, so you can create one yourself. Open vim, and type :e ~/.vimrc
to edit a new file called .vimrc
in your home folder (~
)
We'll start by adding just one setting, so that we can see whether it worked. Add the following text:
" switch on line numbering
set number
The "
is the comment character.
Then, quit vim and restart it - you should find that a line number 1 has appeared at the top left, and you should find that any file you edit from now on has line numbering switched on by default.
3. Installing a plugin
Plugins live in a folder called ~/.vim/
, but, again, vim doesn't create this by default, so you have to make it:
mkdir ~/.vim
Over time, the .vim
folder will grow several subfolders like:
plugin
for pluginscolor
for color schemesdoc
for documentationsyntax
for syntax highlighting modes
But for now it's empty. Let's add one plugin, to try it out.
Start by opening vim with vim .
- that tells vim to open a folder in "explorer" mode. We'll install NERDtree which is a popular file browser plugin, which will replace the default explorer.
Go to http://www.vim.org/scripts/script.php?script_id=1658 and dowload the zip file from the table at the bottom of the page.
Open it up in archive manager, choose "extract", and then tell it to extract into you ~/.vim/
folder. You may need to hit Ctrl+H
inside archive manager's folder browser, to show hidden folders.
Once it's extracted, it will create several subfolders in .vim
for you. If you now restart vim with a
vim .
You should see the explorer view has changed! It's now using the NERDtree plugin.
4. More .vimrc settings
My full .vimrc is available here https://bitbucket.org/hjwp/vim/src, but here are a few settings I find really useful:
" syntax highlighting
syntax on
" map cut & paste to what they bloody should be
vnoremap <C-c> "+y
vnoremap <C-x> "+x
map <C-v> "+gP
" sane text files
set fileformat=unix
set encoding=utf-8
" sane editing
set tabstop=4
set shiftwidth=4
set softtabstop=4
" convert all typed tabs to spaces
set expandtab
"autocompletion with ctrl+space
inoremap <c-space> <c-n>
inoremap <Nul> <c-n>
5. Ctags
I wouldn't worry too much about plugins at first, just getting to know the power that vim offers you out of the box should be useful enough to your coding already. But one thing that really is useful to have working in vim is ctags. ctags lets you do things like "jump-to-definition", and autocomplete across all the keywords in your source tree. start with:
apt-get install exuberant-ctags
Then, in your .vimrc, add
map <f12> :!ctags -R .<cr>
Now, when you hit "F12" in a vim session, it will generate a .tags
file, which vim can use to scan for keywords.
Now, if you're on, eg a function call in your source code, you can use ctrl+]
to jump to its definition. More info here: https://stackoverflow.com/questions/563616/vim-and-ctags-tips-and-tricks
6. what's next
Other people have posted some really useful-looking guides, here's a couple of SO pages I've found useful tho:
- https://stackoverflow.com/questions/95072/what-are-your-favorite-vim-tricks
- https://stackoverflow.com/questions/726894/what-are-the-dark-corners-of-vim-your-mom-never-told-you-about
- https://stackoverflow.com/questions/164847/what-is-in-your-vimrc
It's a whole vim-world out there. But: warning: If you find yourself getting into vim golf, you've probably gone too far - http://vimgolf.com/ ;-)
I'd suggest you start studying .vimrc's just like the one above. Everyone's needs and preferences are different so you should denfinitely go with manually installing stuff instead of just copying someone elses configurations.
Some resources about learning VIM itself:
- Learn Vim Progressively, a great guide about learning Vim.
- Vim Novice Tutorials, a series of videos by Derek Wyatt I enjoyed myself when I first began my journey.
- Cheat Sheet, if you're not familiar with Vim from before I'd recommend going at this like an examination. Write the keybindings down on a paper, the command on the left and the description on the right. Then start memorizing by hiding either the command or the description and trying to remember the answer. Doesn't take long before the commands come naturally to you, but remember to actively use them in Vim as well, otherwise you'll quickly unlearn.

Some really useful plugins
- Syntastic Static code analysis for tons of languages
- vim-css3-syntax Syntax highlighting for CSS3. Generally you should update the syntax files for HTML5 and Javascript as well, if you use them that is.
- Matchit Extends the functionality of %
- Surround Mappings for tags/parenthesis etc, really powerful for Web Devs
- Tcomment Easily toggle comments in most languages
- Pathogen Keep your vim folder organized so you can uninstall and play around with plugins
- NERDtree A really popular tree explorer, personally though I prefer just :e .
- Command-T A popular buffer manager, personally I can't use it as it depends on ruby.
- Snipmate Easily insert code snippets.
- Sparkup Extend div#stuff.class > ul > li*5 into HTML, you get the drift.
Some other good to knows
- To get tabcompletion for projects you can use ctags which vim supports
- Rebind caps-lock to esc, after one day you can't understand how you had the energy to reach all the way to esc.
- Vim has branched undo trees, meaning you can still undo even though you altered your undo tree.Gundo helps you visualize this.
- Vim has persistent undos, meaning it saves your undo history even if you restart your computer, you should definitely enable this.
- In my own vimrc I have a function which checks if I'm working on a Drupal or a Wordpress site, depending on this different code conventions are set. (Guess this could be useful to know, you can find it in my repository linked below.)
- Steve Losh had this awesome config defining a Number Object in vim so you can delete/change/etc only the number in for example 200px by pressing cN
Vimrc repositories worth checking out
- Steve Losh Awesome stuff
- Tim Pope Creator of Fugitive, Surround and tons of other vim plugins
- Oxy My own repository, in the README I have an example for generating ctags for Drupal projects.
- Derek Wyatt His screencasts taught me vim, you can find alot of cool stuff there
