Use a different directory for plugins

[SingularisArt]

This isn't an issue, it's just a question.

I'm currently working on multiple NeoVim configurations at once, and I want to store each configuration's plugins in a different directory. How do I go about doing that? Also, on a different note, how can I have each configuration use a different cache directory as well?

To do this you would have to manage vim's runtimepath and packpath. See the help for both runtimepath and packpath as they have a lot of detail explaining how vim finds and loads files.

Here is a quick example of setting up runtimepath, packpath, and packer.

local sep = vim.loop.os_uname().sysname == 'Windows_NT' and [[\]] or [[/]]
local function join(...)
  return table.concat({ ... }, sep)
end

local home = os.getenv 'HOME'
local len = #home

local homepath = join(home, '.config', 'config-name')
local cachepath = join(home, '.cache', 'config-name')

-- Add path locations for configuration
local rtp = { homepath, cachepath }

-- Add paths that dont start with home.
for _, p in ipairs(vim.opt.runtimepath:get()) do
  if p:sub(1, len) ~= home then
    rtp[#rtp + 1] = p
  end
end

vim.opt.runtimepath = rtp

-- Packer paths and files
local pack_path = join(cachepath, 'site')
local package_root = join(pack_path, 'pack')
local compile_path = join(cachepath, 'plugin', 'packer_compiled.lua')
vim.g.loaded_remote_plugins = 1

vim.opt.packpath:prepend(pack_path)

local packer_bootstrap = false
local packer_install_path = join(package_root, 'packer', 'start', 'packer.nvim')
if vim.fn.isdirectory(packer_install_path) == 0 then
  vim.fn.system { 'git', 'clone', 'https://github.com/wbthomason/packer.nvim', packer_install_path }
  vim.cmd.packadd 'packer.nvim'
  packer_bootstrap = true
end

require('packer').startup {
  function(use)
    use 'wbthomason/packer.nvim'
    -- ...

    if packer_bootstrap then
      require('packer').sync()
    end
  end,
  config = {
    package_root = package_root,
    compile_path = compile_path,
  },
}
