If you are using Linux and haven’t familiarized yourself with the world of VIM yet…then you need to rethink your text editing habits. Alright, so that’s a little harsh, but did you know that with a few changes to your .vimrc file (stored in your home directory) you can mold VIM into a very powerful Integrated Development Environment (IDE)?! Then if you stack on a few plugins like ‘Nerd Tree’ and ‘Exuberant C-Tags’ you have an development environment that rivals any paid application.
Here are a few of my favorites:
" First turn on the plugins for the tabs and syntax highlighting " Enable loading filetype and indentation plugins filetype plugin on filetype indent on " Turn syntax highlighting on syntax on " Use 2 spaces for (auto)indent set shiftwidth=2 " Don't highlight results of a search set nohlsearch " When a bracket is inserted, briefly jump to a matching one set showmatch
Here’s a full text copy of my .vimrc file. Keep in mind I have Exuberant C-Tags, Omni-Complete and Nerd Tree also in use so those are in my mappings.
