My WIP neovim config and nix overlay/shell

##install:

clone https://github.com/rasmusm/nix-neovim.git
ln -s  $(pwd)/nix-neovim $HOME/config/nvim  # optinal to this config as the default $USER config for nvim

This are only to help with the examples

cd nix-neovim           # optinal for examples
export $GITROOT=$(pwd)  # optinal for examples

on first run install the plugins with :PLugInstall

Nix stuff

Use the overlay like: pkgs = import <nixpkgs> { overlays=[ (import ./pkgs/neovim-overlay.nix) ]; } to get set pkgs to with nvim overwrite with the new version (see the wiki for an example)

Use the shell.nix by running nix-shell (or nix-shell $GITROOT/shell.nix if $PWD are not $GITROOT) get a nix-shell with the new nvim and the dependencies (not for all lsp, but most)

right now i do not use nix to handle plugins except for the ones there requires building

niv are used for manage version of sources, except for sumneko-lua-language-server there are using nix-prefetch-git until niv supports git submodules.

there are nix packages for some tools/addons in pkgs/

pkgs/sumneko-lua-language-server.nix for https://github.com/sumneko/lua-language-server
pkgs/tree_nvim.nix for https://github.com/zgpio/tree.nvim

Thees are not added with the neovim-overlay

Nvim

I fail in love with the layer system that CraftedCart have made based on spacemace.

lua modules and structure

c/ are general commands and libs
l/ are layers

layers

A layer are like a module but for configs, a layer are a dir under l/ with the name of the layer eg.

$GITROOT/lua/l/colors/init.lua are the base of a layer called colors

a layer must at lest have this functions (the name layer can be anything and are not exposed):

local plug = require("c.plug")

local layer = {}

--- Sets plugins required for this layer
function layer.register_plugins()
  plug.add_plugin('romainl/flattened') --example
end

--- Init config for theis layer
function layer.init_config()
  vim.g.ilovenix = 1 -- example
end

return layer

they are called at the right time by c.layer

To load a new layer simple add layer.add_layer("l.colors") to `$GITROOT\lua\init.lua (excthange l.colors with the name of the new layer.

Plugings

use :PlugStatus to see if the are updates to plugins
use :PlugUpdate to update plugins
use :lua require("c.plug").('vim-airline/vim-airline') insted of Plug('vim-airline/vim-airline')

c.layer.lua handels the real call to Plug
