I was considering completely redesigning the implementation. Let me draft something here before we start writing code!

What we have now

Two hardcoded arrays, one for where to find the app/lib source code {"app", "lib", ""} and another one to find testes, {"test", "spec"}. Basically, we take the path of the current file, and use these locations to:

1. replace the relative root directory and the file suffix (eg app/model/whatever.rb to spec/model/whatever_spec.rb)
2. test if this new path exists (same in line 97 BTW)

In theory, it looks fine, but every now and then I find edge cases.

My new idea

Comparison

This will be a table like:

{
    path: "app/models/whatever.rb",
    parts: {"models", "whatever"},
}

Steps to build it:

Step	App example	Test example
Start with a path	app/models/whatever.rb	spec/models/whatever_spec.rb
Drop extension	app/models/whatever	spec/models/whatever_spec
Drop default directory names such as lib, app, test, spec	models/whatever	models/whatever_spec
Drop default test suffixes	models/whatever	models/whatever
Convert to an array	{"models", "whatever"}	{"models", "whatever"}

Cache

Probably at first use, we can walk the project directory and create these tables for every Ruby file in the project. This can take a while, but we cache.

:RubyAlternate

1. Calculates the comparison object for the current path
2. Find the closest match in the cache using something like Levenshtein algorithm to be tolerant to small deviances (e.g. app/controllers/login.rb would probably match with spec/requests/login_spec.rb)
3. If we cannot find, we rebuild the cache once
4. if we still cannot find, return nil

I think I'm going to work on this in the following weeks

Or… maybe… we leave it to a 3rd party https://github.com/rgroli/other.nvim
