Add-on: How can I configure rubyLsp.indexing.includedPatterns from my add-on?

[kozy4324]

I am developing an add-on for Rake:
https://github.com/kozy4324/ruby-lsp-rake

I’d like to configure rubyLsp.indexing.includedPatterns from my add-on to include a pattern like **/Rakefile* , but it seems there is no way to do so. How can I configure this? Or do you have any plans to create an API for such a use case? If adding such an API is possible, I’d be happy to submit a pull request. Thank you for your consideration!

@kozy4324 there may be a way do this currently, but I haven't verified:

In an add-on, you have access to @global_state, and from that you can get a reference to the index so you could try index.apply_config(...) (see configuration_test.rb for an example).

(cc @st0012).

@andyw8 Thank you for your help!

@index.configuration.apply_config({ "included_patterns" => ["**/Rakefile"] }) call in the Addon#activate method works well 👍

I thought there might be some concerns about making this a public API, but if this approach is acceptable, I believe we can close this issue.

@kozy4324 that's good to hear that it works.

You're right, this isn't ideal as a public API. An add-on could change configuration in a way that is detrimental to other add-ons, or overwrite a user's config.

I think a better API would look something like:

@index.configuration.include_pattern("**/Rakefile")

and its implementation would append to included_patterns (but not overwrite any existing values).
