Kate (and now Kdevelop) support LSPs, so you should get the same autocomplete experience as VS code.

Note that some LSPs are not what I would call lightweight. You might have a lighter experience using Kdevelop's python support, rather than an LSP for example (I've not tested though). Or research to see if alternate LSPs are available for a language.

From what I can tell, raylib is just a library? In which case it should work with any autocomplete (Kdevelop or LSP) for whichever language you use.

Kate includes many default LSP configurations, and links to their download pages in it's LSP settings. LSPs may also be available in your system's package manager.

If you still like the workflow of VS Code and just want it without the Microsoft Ai and spyware crap, Then you got Vscodium.

It's basically the open-source code of VS Code compiled without the invasive M$ stuff.

Would you consider kdevelop? Its part of KDE https://kdevelop.org/

If you install the language server for your language, then you can get hints, including function arguments and types, in Kate.

See https://microsoft.github.io/language-server-protocol/implementors/servers/ for a list of server

I'm not familiar with raylib specifically, but generally as long as you have header files (for C) or stubs (for python) you should be able to get completions for library calls.

But it seems like you already know about LSPs from your comment. So I'm not sure exactly what your question is? Do they work?

If you don't get the answer you are looking for here, get yourself to our Discuss forum. Devs hang out there often and they may be able to help you.

i think this is all about configuring the lsp server (e.g. clangd in the case of c), pretty sure you can get it working with kate

Sorry I'm not a dev and can't answer your questions, just got curious: you're asking how things like autocompletion would work with Raylib. What's Raylib, and why would it need something special and not work the same way everything else works?

I don't do development but I still like coding in Python and like to know about development.
