Noir

Noir is an in-game Lua scratchpad for Garry's Mod. It provides a code editor, a REPL, a file browser, and an execution layer that runs code across realms (self, server, clients, or shared). It is built on gmod-monaco and runs best on the GMod chromium branch.

Features

• Run code anywhere on self, server, all clients, a specific client, or shared. Return values and captured output (print, Msg, errors) are sent back to the console, including output from hooks and timers that fire after the run.
• REPL console built on the same Monaco editor, with foldable results and clickable @file.lua:line links to function definitions.
• JIT decompiler (jit_decompiler2): reconstructs readable Lua from LuaJIT 2.1 bytecode for functions with no source on disk, resolving constants, upvalues, and real local names.
• easylua-style helpers: me, this, there, dir, search tables (all, us, bots, props), and last; unrecognized identifiers resolve through entity search.
• In-world entity picker: point at, list nearby, or filter entities by class/model and pass the reference back to your code.
• Find in Files: searches every Lua file locally and on the remote server, on a per-frame time budget with an accurate progress bar (Ctrl+Shift+F).
• Autorun: runs a configured list of scripts on load, with crash protection that disables autorun if a script crashed the game.
• File browser for opening and saving across DATA, LUA, and GAME paths.
• GMod-aware autocomplete covering the API (functions, methods, enums, hooks) plus your live runtime tables, with wiki docs on hover.
• luacheck diagnostics as you type.
• Monaco editor features: command palette, code folding, tabs, activity bar with file tree, snippets, minimap, and a custom theme.
• NDL: a debug library (NDL global) with function detours, argument filters, and call tracers.
