LuaHelper VS lua-language-server

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aka Sumneko Lua is not the only Lua Language Server implemented in LSP standard, there are 3 I know of, one no longer maintained and the other is Tencent/LuaHelper (https://github.com/Tencent/LuaHelper)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

Yep. Luau has an LSP so you should be able to get all that.

There is no support for Luau in Love2D though. You would have to author your code in Teal (typed lua to lua compiler) and then compile that to Lua to be run in Love: https://github.com/teal-language/tl

You can get the Lua LSP working in Love2D with full completion support by the way. The Lua LSP has 3rd party libraries included in it. You can see all the preinstalled ones here: https://github.com/LuaLS/lua-language-server/tree/master/3rd

Support for them as built-ins will be removed at some point though. But you can always add them yourself: https://github.com/LuaLS/lua-language-server/wiki/Settings#w... using the files from here: https://github.com/LuaCATS/love2d/

It looks like the easiest way to support them is using a `.luarc.json` file though: https://github.com/LuaLS/lua-language-server/wiki/Configurat...

Here is a project that is already set up with a config file that you should be able to just copy: https://github.com/jonasgeiler/love2d-joystick-tester/blob/m...

Fennel is indeed nice and I rewrote my config too, but looked back ~2 years later and rewrote in again in Lua. I think Fennel for configuration is not justified and just adds complexity. Also the tools are not there: two existing language servers[1][2] can't compete with Sumneko's Lua language server[3] and they are fennel-exclusive and clueless about Lua code. I still like Fennel for writing more complicated code (my plugins: [4][5]) because of neat features like pattern matching and structural decomposition, both are surprisingly robust and I had doubts initially.

Lua supports most of this primarily through community packages. luarocks is the Lua package manager. Lua does not ship with a unit testing framework by default, but the community seems to have selected luaunit as the defacto testing library. LSP and linting support is provided through the lua-language-server and code formatting is handled through stylua. However, I can't find tooling similar to Python's bandit to perform security audits. I believe this to be an open area of Lua library development.

I just started using lua and have types in vscode using lua annotations. https://github.com/LuaLS/lua-language-server/wiki/Annotation...

There is https://github.com/LuaLS/lua-language-server

> Edit: FYI I use IntelliJ with Lua support,

In other words, you don't like Lua, because your favorite IDE doesn't support it? (Or maybe it does, when you install the aforementioned language server)

Check the documentation of lua_ls

You can use LLS extension for VSCode. Documentation: https://github.com/LuaLS/lua-language-server/wiki/Annotations

There's lua-language-server which works with types defined in definition files and/or annotations in comments.

Lastly, neovim now supports semantic token highlighting which uses semantic tokens from LSP servers to provide even better, language specific highlighting. Some LSP servers support semantic tokens for doc comments. The lua language server is a good example. Unfortunately, if you're using a language like C or C++, the language servers do not provide semantic tokens for comments because doxygen style comments are not specific to those languages so you might be out of luck for semantic token highlighting.

I think it is because the language server send a different type for the first line: https://github.com/LuaLS/lua-language-server/blob/eeffd1462b892fda5d01282acf840ba0e154e467/script/core/hover/label.lua (might be one of the other files here, not label)
