I keep my vimrc and tmux configuration files in this repo. Really good if you're a command line developer (like me).
This is my standard configuration for the vim that I run on my laptop. Some links for plugins that I use for autoformatting and autocomplete, respectively.

This is a file that configures tmux to perform like vim. Note: a friend of mine made this, I just use it. Note that I run tmux3.0a.
