now that home-manager always generates an init.lua we can take the
wrapper output instead of reimplemnting stuff in HM (notwithstanding rtp
changes that are not needed in HM).
This is necessary to keep the provider configuration available after
this change https://github.com/NixOS/nixpkgs/pull/487390
Also updated test to reflect ruby disabling
so alternative GUIs can find lua dependencies that are not plugins (for instance nio).
Some plugins depend on lua packages that are not vim plugins and thus
become "invisible" to nixpkgs as it stands.
For now they need to be specified manually via `extraLuaPackages` but
hopefully we can autodiscover those in nixpkgs.
Fix an issue where the generated ~/.config/nvim/init.lua lacks a newline after the vim.cmd [[source ...]] directive. Without this newline, subsequent lua configuration is concatenated onto the same line, breaking lua syntax.
init.lua Before:
vim.cmd [[source /nix/store/...]]vim.opt.rtp:prepend(...)
After:
vim.cmd [[source /nix/store/...]]
vim.opt.rtp:prepend(...)
