Slim Vim

A simple .vimrc and .tmux.conf file

Using vim and tmux together is a surprisingly good development setup that can be done all on a terminal. Useful for when you need to do a bit of devving on a server but don't want to faff around with vundle

Config explained

Tabs

set tabstop=4
set shiftwidth=4
set expandtab

By default vim will insert tab characters and they'll be 8 spaces long.

This converts them to spaces and makes them 4 spaces long

Auto Indent

set autoindent

This will automatically move your cursor to the right position when you start a new line:

Before

function hello() {
    test// <-- hit return here
// <-- cursor will go here
}

After

function hello() {
    test// <-- hit return here
    // <-- cursor will go here
}

Wildmenu

set wildmenu

Improves command mode completion, helps with the fuzzy search as you can tab through results

Leader

let mapleader = ","

The leader key is your go-to shortcut key. This can be changed to whatever you feel more comfortable with, but comma works quite well

JF

inoremap jf <esc>

Very simply makes it easier to drop out of insert mode into normal mode, just type jf

Fuzzy Search

nnoremap <leader><leader> :e **/*

This one is really useful, this just uses vim's autocomplete for a poor man's fuzzy search.

You'll end up with :e **/* in command mode, you can search by typing your partial file name and hitting tab, e.g. :e **/*TestCase

Highlighting

nnoremap <leader><space> :nohl<cr>

This clears vim's highlights after using /

Easy command mode

nnoremap ; :

Instead of having to press shift and ; you can just press ;

Tabs

nnoremap <C-n> :tabnew<cr>
nnoremap <C-l> :tabn<cr>
nnoremap <C-h> :tabp<cr>

Vim has pretty nice tab support out the box, these mappings just make it a bit more intuitive

Ctrl+n - new tab

Ctrl+l - next tab

Ctrl+h - previous tab

Tips

Asides from the basic vim shortcuts and modes, there are some other nifty features that come out the box

Shell Commands

You can execute shell commands with :!

For example :!pwd

Splits

If you're not familiar with vim splits, you can split a window in half with either :vsp or :sp

You can cycle through splits by double-tapping Ctrl-W

File explorer

If you try to :e a directory, vim will instead open a file explorer.

You can open one in your root directory with :e .
