This article assumes you are using Neovim (version 0.8.0 or higher) and packer.nvim to manage your plugins. Adding the following loads the LuaSnip plugin, creates a snippet for “func”, and maps “Ctrl + p” to expand the snippet and jump through the fields.

vim.keymap.set() coc to confirm completion with lua
I’m currently rewriting my Neovim configuration using lua rather than using vimscript. I’m using the coc.nvim plugin and want to map return (
Vim JSON Format
Vim allows you to run all (or some) of your content through an external program. In this case, we want to use Python to format (i.e. pretty print) our JSON with ‘python -m json.tool’. We an also setup a Vim user defined command to reduce typing (and make it easier to remember).
Use CTRL-[ as Esc in Vim
The Esc key is not a convenient key to hit on the keyboard. While many will recommend you map another key to act as your Esc key, by default you can use Ctrl-[ instead.
Vim Easy Align Custom Rule for $
I use Junegunn’s Vim plugin vim-easy-align to make it easier to align my code. This plugin does not have a default mapping for aligning the dollar sign ($). Because the plugin is designed to be extensible, I was able to add support for aligning by the dollar sign ($) by adding some lines to my .vimrc file.
Vim Close All Buffers Except the Current One
Vim has a built-in command to close all windows except the current one (:only), which is nice for focusing on a single buffer. Sometimes I want to cleanup my buffers by closing all of the buffers except for the current one. This custom command is like :only for buffers instead of windows.
Brew Failure in Upgrading to the Development Version Neovim
I wanted to run the latest development version of Neovim (0.4.0) to use some of the latest features (e.g. the floating window). Unfortunately, my attempts to install it were failing. These are my notes on the problem and how I fixed it.
Vim netrw duplicate file
When using Vim sometimes I want to duplicate a file, however the default file explorer in Vim (netrw) does not handle this well. This is a Vim mapping I created to make duplicating a file easier.
Vim Find Your Leader
When using Vim you can find your <Leader> by using echo for the value of “mapleader”, however there are some edge cases that make this less than ideal. If “mapleader” is undefined an error is thrown instead of showing the default <Leader>. If “mapleader” is not a visible character (e.g. <Space> or <Tab>), you can not see the value. I use the following command to display <Leader> while working around these edge cases.
Vim, tmux, iTerm broken colors
I do most of my work in Vim (or Neovim) in tmux inside of iTerm on my Mac. I found my color schemes were being properly applied in Neovim but not in Vim (version 8). Adding two lines to my .vimrc corrected the problem for me.
