vim-autoformat

Format your code with only one button press! This plugin makes use of external formatprograms to achieve the best result. Check the list of formatprograms to see which languages are supported by default. You can easily customize or add your own formatprogram.

How to install (Vundle)

Put this in your .vimrc

Bundle "Chiel92/vim-autoformat"

How to use

First you have to install an external program that can format code of the programming language you are using. It suffices to make the formatprogram globally available, which is the case if you install it via your package manager. Alternatively, you can put the binary (or a link to it) in the formatters/ folder.

When you have installed the formatters you need, you can format the entire buffer with the command :Autoformat. For convenience it is recommended that you assign a key for this, like so:

noremap <F7> :Autoformat<CR><CR>

If you don't want to format the entire buffer, you can alternatively format visually selected code with gq. However, some formatprograms will behave a bit weird this way, because they need the context of a piece of code. For more ways to perform autoformatting type :help gq.

Default formatprograms

Here is a list of formatprograms that are supported by default.

• astyle for C#, C++, C and Java. It's probably in your distro's repository, so you can download it as a regular package. For Ubuntu type sudo apt-get install astyle in a terminal. Otherwise, download it here: http://astyle.sourceforge.net/.

• jsbeautify (the python CLI version) for Javascript. This one can also be installed as a vundle package, and I recommend to do so. Put this in your .vimrc: Bundle "einars/jsbeautify". Note that we're only using the python version, so node doesn't have to be installed. Here is the link to the repository: https://github.com/einars/js-beautify.

• autopep8 for Python. It's probably in your distro's repository, so you can download it as a regular package. For Ubuntu type sudo apt-get install autopep8 in a terminal. Here is the link to the repository: https://github.com/hhatto/autopep8. And here the link to its page on the python website: http://pypi.python.org/pypi/autopep8/0.5.2.

• tidy for HTML and XML. It's probably in your distro's repository, so you can download it as a regular package. For Ubuntu type sudo apt-get install tidy in a terminal.

How can I change the behaviour of formatters?

The formatprg for a <filetype> is defined in g:formatprg_<filetype>. The arguments passed to the formatprogram are defined in g:formatprg_args_<filetype>. So, a complete definition could look like this:

let g:formatprg_cs = "astyle"
let g:formatprg_args_cs = "--mode=cs --style=ansi -p -c -H"

If you are not satisfied with the default configuration, you can override it by defining these variables in your .vimrc, just like above.

If you changed the tabwidth for a formatprogram, I would suggest to change the indent options of vim correspondingly for that filetype.

au filetype *.cs set tabstop=2
au filetype *.cs set softtabstop=2
au filetype *.cs set shiftwidth=2

Todo list

• Check for windows support.
• Option for on-the-fly code-formatting (like visual studio)

If you have any suggestions on this plugin or on this readme, if you think some default formatprg definition is missing, or if you experience problems, please contact me by creating an issue in this repository.

Change log

March 10 2012

• The custom_config branch has been merged into the master branch. This means that customization of formatprograms can be done easily now, as explained above.
• I also set the default tab width to 4 for all formatprograms, and in vim itself.
• Finally, the default parameters for astyle have been slightly modified: it will wrap spaces around operators.
