Setting path in init.lua

Question

One of my packages needs me to set up the PATH and one variable. In my vimscript code I had:

let $PATH.=':/usr/lib64/openjdk-11/bin/'
let $MYVIMRC='/home/luis/.config/nvim/init.vim'

But I can't figure out how to do this in an init.lua file. If I try to wrap around vim.cmd([[]]) the package still does not detect these changes.

Neovim has an API for getting and setting environment variables in Lua: vim.env.

Using vim.env, you can add to your path with this:

vim.env.PATH = vim.env.PATH .. ':/usr/lib64/openjdk-11/bin/'

In the same vein, you can set $MYVIMRC with:

vim.env.MYVIMRC = '/home/luis/.config/nvim/init.vim'
