Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@maplestoryworlds/mlua-lsp

Launcher and host for the official msw.mlua Language Server. Exposes LSP as a cross-platform CLI for AI agents/scripts, and as a standard stdio server for editors. Does not implement an LSP itself — wraps msw.mlua's languageServer.js.

Install

npm install -g @maplestoryworlds/mlua-lsp

First run uses the bundled msw.mlua VSIX — no VS Code installation required.

Quick start

# Diagnostics on a .mlua file
mlua-lsp diagnose /path/to/project RootDesk/MyDesk/MyScript.mlua

# Hover / completion / definition  (line and col are 1-based)
mlua-lsp hover      /path/to/project RootDesk/MyDesk/MyScript.mlua 10 5
mlua-lsp complete   /path/to/project RootDesk/MyDesk/MyScript.mlua 10 5
mlua-lsp definition /path/to/project RootDesk/MyDesk/MyScript.mlua 10 5

# Prewarm the persistent host before first edit (use in SessionStart hooks)
mlua-lsp start  /path/to/project

# Inspect host state
mlua-lsp status /path/to/project
mlua-lsp dump   /path/to/project

The first CLI call spawns a persistent TCP host (~1.7 s cold start). Subsequent calls reuse the warm host with 30–50 ms responses. The host self-terminates after 30 min of inactivity.

Modes

| Mode | Entry | Use case | |---|---|---| | CLI (persistent host) | mlua-lsp <cmd> <project> ... | AI agents, hooks, scripts | | stdio proxy | mlua-lsp serve <project> | Tooling sending many requests | | LSP server | mlua-lsp server --stdio | VS Code / Cursor / Neovim | | One-shot | mlua-lsp <cmd> ... --no-daemon | Debug, offline fallback |
