when coc-bitbake is enabled, vim got stuck for minutes then ask for configuration

[laoshaw]

I had vim-bitbake and coc-bitbake both on, when I open a bb file, it gets stuck. removing vim-bitbake still the same, when it's stuck, watchman is running with lots of cpu load. uninstall coc-bitbake and enable vim-bitbake, it become usable with either language-server-bitbake or bitbake-language-server. question: do I need vim-bitbake when coc-bitbake is installed? question: why it's unusable? screenshot and log below:

I think it is because there are too many files in the working directory, scan them cost too many time for watchman.

I think it is because there are too many files in the working directory, scan them cost too many time for watchman.

any workaround for that? my local directory when I invoke vim is actually just a few files, not sure why watchman is tied up.

can vim-bitbake co-exist with coc-bitbake?

Thanks

[Freed-Wu]

For me, there are many files in build. However, I don't install watchman.

Yes.

[laoshaw]

even after I removed build/, coc-bitbake will still get stuck:

[Freed-Wu]

I doubt it is a bug only happened when user installed watchman.

[laoshaw]

per my test, it's not the case, I uninstalled watchman, it's still stuck. it also acts the same for both bitbake-language-server and language-server-bitbake. I move a recipe to a separate dir to get rid of any build/ etc, still the same. I think it's somewhere in coc-bitbake. I wonder, what coc-bitbake brings here? will vim-bitbake + coc-settings' bitbake-language-server be enough already? Thanks

[Freed-Wu]

Before it is fixed, use coc-settings is enough.
