Question: How to enable the autocompletion support of the pkgs besides Glib

wszqkzqk opened this issue 2 years ago · 7 comments

The addon now cannot treat using Gee correctly and treats it as an error The namespace name Gee' could not be found`, is there any way to enable the autocompletion support?

Answer 1 · 2022-08-06T21:13:02.000Z

The language server needs to understand the compiler flags for your source file(s). Gee could be a namespace belonging to anything. Therefore, you need to tell VLS to use --pkg gee-0.8, either by specifying this in your meson.build file in the project root dir or by putting #!/bin/env -S vala --pkg gee-0.8 at the top of your file¹.

Generally you'd only do this if your source file is a Vala script. ↩

Thank you for your explanation! It works now.
I didn't know vala can also support JIT before. This is really a useful feature.
Something else, the arg. -S may need to be passed at first for env to recognize.

Answer 3 · 2022-08-07T17:19:50.000Z

@wszqkzqk right, the -S comes after env and before vala.

This is not JIT'ed code by the way, since it's not compiled piecewise or with no optimizations. It's not interpreted at all---Vala just compiles the whole file into a temporary executable and runs that.

It seems that lsp still cannot work with meson on windows.

Answer 5 · 2022-11-17T00:22:22.000Z

@wszqkzqk what does VLS say? Are you mixing MSYS2 VLS with Win32 Meson?

@Prince781
I'm using meson and vls from msys2 usrt64, and the output was:

Also, vls often fail because it cannot find and show doc on windows, so there may also need a option to disable it.

@wszqkzqk please open a new issue on vala-language-server describing your problem with Meson on Windows. Also, please enable debug messages in the extension settings.
