Problem: We want to encourage implementing core features in Lua instead of C, but it's clumsy because: - Core Lua code (built into `nvim` so it is available even if VIMRUNTIME is missing/invalid) requires manually updating CMakeLists.txt, or stuffing it into `_editor.lua`. - Core Lua modules are not organized similar to C modules, `_editor.lua` is getting too big. Solution: - Introduce `_core/` where core Lua code can live. All Lua modules added there will automatically be included as bytecode in the `nvim` binary. - Move these core modules into `_core/*`: ``` _defaults.lua _editor.lua _options.lua _system.lua shared.lua ``` TODO: - Move `_extui/ => _core/ui2/`
