Generate "compile_commands.json" for LSP ready IDEs

[pvonmoradi]

The following command generates the requires files for LSP for plugins like coc-nvim:
pio project init --board my_board --ide vim --project-option "framework=arduino"
Problem is, after mutating the platformio.ini and adding libraries, the .ccls file is not kept updated.
How to make it so that all these auxiliary helper files get updated when project dependencies change? I was able to do it with
initing again.
Aside from that, I don't think the .ccls file should be dependent on project libs alone. Maybe the source does not use a library, so its deps should not be handled by ccls.

@ivankravets Thanks. So it is a known issue.
Is generating the compile_commands.json via the post: script and compiledb command, a good alternative? (meaning pointing LSPs to compile_commands.json instead of .ccls)
And how does VScode handle this issue?

I updated the title. It is a very good idea to generate compile_commands.json for all compatible IDEs. Thanks!

@ivankravets But isn't this already implemented? https://docs.platformio.org/en/latest/integration/compile_commands.html
Or you mean you are planning the --ide switches to generate this in the project root?

Yes, it makes sense to generate compile_commands.json in the root of project.
