acme-lsp VS LuaHelper

They use acme-lsp btw.

Yes. There's [acme-lsp](https://github.com/fhs/acme-lsp) for providing language server integration and things like "jump to definition", "show hover-help" and so on.

I personally use `autokey` on Linux and `sxhkd` on macOS for adding a key binding for `acme-lsp`'s `Lcomp` command which performs completion.

There's also [Watch](https://pkg.go.dev/9fans.net/go/acme/Watch) for monitoring a directory of files for changes and running a command in a persistent Acme window. I use that for continuously running unit tests while I edit some piece of code, or for automatically running `go generate` and such.

For your REPL needs, there's the `win` command that implements a basic dumb terminal as an Acme window. This provides a few goodies like letting you edit the terminal buffer with Acme's `Edit` command and its embedded Sam command language, as well as adding "snippets" that can be executed with one click of the middle mouse button.

Acme by itself is already plenty useful (`win` is part of the "standard distribution" so to speak, in that it is part of the various Plan9 forks and of plan9port), and a lot of extra stuff can be built rather quickly by hooking into its 9p interface:

For example, my tool to add commonly used tools to the tag (the blue line at the top of each text window that contains the file name and commands that act on the window) is a handful of lines of shell script that parse entries in acme's `acme/log` file and select the appropriate tools to add based on the name of newly opened files.

My Git integration is a thin wrapper around `win` and `git commit --interactive` that pops open a window that allows me to author a Git commit similar to (but a lot simpler than) magit for emacs and fugitive for Vim work.

Even if you're not in Plan9 (or one of the forks), I encourage you to give [plan9port](https://github.com/9fans/plan9port)'s Acme a spin.

(FWIW, this post was written in an Acme window because it's a lot more intuitive to use after some getting used to than regular ol' GTK text boxes used by Firefox.)

LuaLS/lua-language-server aka Sumneko Lua is not the only Lua Language Server implemented in LSP standard, there are 3 I know of, one no longer maintained and the other is Tencent/LuaHelper (https://github.com/Tencent/LuaHelper)

I'm using lua-language-server, but there's also lua helper. Try both (separately) and see which fits you best.

Hi, there's a new Lua server luahelper being actively developed here: https://github.com/Tencent/LuaHelper. It is written in Go and claims the abilities of real-time detection, millisecond output detection results, perfectly support editing and testing of 1000+ file project.
