VimLint is, you guessed it, a sourcecode checker for your .vimrc (and all other Vimscript)! It finds common problems such as:

• Trying to use (ex-)commands that do not exist
• Missing the if or endif in if...endif.
• Incorrectly using options, f.e. set compatible=3 would be incorrect as only set compatible and set nocompatible are allowed.
• Incorrect syntax for mappings.
• And many more...

It works together with Syntastic, which is an amazing Vim plugin that uses external source code checkers to find and highlight errors.

All the cool kids are using it, and so should you!

If you'd like to lint your entire ~/.vim folder:

find ~/.vim -name *.vim | xargs vimlint | tee out.txt

Enjoy!
