This my Neovim configuration.

Most of the configuration should work with standard Vim as well, though I haven't tested it.

Some of the custom keybindings I set up are:

• <leader>t Toggle tagbar
• <leader>r Toggle RainbowParentheses
• <leader>u Toggle Undotree
• <leader>m Build CMake project

• Use :CheckHealth to show the health of your Neovim installation.
• Consider having a look at the Neovim FAQ.

If you use Neovim together with tmux, consider adding the following to ~/.tmux.conf:

set -g default-terminal "screen-256color"
set -g mouse on
set -s escape-time 10

If tmux does not show colors correctly, then that might be because it didn't recognize your terminal emulator as supporting them. This occurs for example with PuTTy. Run tmux with the -2 flag to force it to use 256 colors:

tmux -2
