Module: Rvim::Lua::Loader

Defined in:
lib/rvim/lua/loader.rb

Overview

Configures Lua’s package.path so require(‘foo.bar’) walks &runtimepath looking for lua/foo/bar.lua and lua/foo/bar/init.lua, mirroring NeoVim’s behavior. We refresh package.path lazily before any require by replacing it on each install — for v3.5 a single-shot at runtime startup is sufficient since runtimepath rarely changes mid-session, but :runtime/ :packadd are also expected to refresh it (handled in a small hook).
