Create `vala-language-client` to debug the language server #227

Open albfan opened 2 years ago

albfan commented 2 years ago

I'm trying to setup a complete workflow for vala.

Adding https://github.com/mesonbuild/meson/pull/9582 to meson, one can do:

mkdir -p home/alberto/tutorial/vala-lsp
cd home/alberto/tutorial/vala-lsp
git init
meson init --language vala
vim
:e sample.vala

With a correct setup, vim-lsp or similar work (if setup as mentioned in this project README.md)

so far so good, but after that, debug is little complex

I enable vim-lsp debug and extract basic operations:

So after run this server: (it is listening on stdin)

$ vala-language-server

Initialize:

Hope this helps others to start with lsp and extend, improve features.

Good to have: Miss a vala-language-client (connected by socket? or localhost) to launch queries. Even a GUI would be awesome (as a side project)

Also, with respect to improving debugging, see #26 and #203

albfan commented 2 years ago

I will try to add test if I manage to understand all this stuff and lsp specs

esodan commented 2 years ago

I have started to add VLS unit tests in GVLS, in order to test GVls' LSP client against VLS server.

First simple test, just initialize the server and got (just to show how is going on):

$ meson test vls-initialization --gdb
