Motivation
Closes #3845
RubyLSP will helpfully log the formatter and linter detected, but not indicate
how or why it came to that conclusion. This can make it difficult to ascertain
whether the detection was correct.
Implementation
The detection methods for formatters, linters, test libraries, and type checkers
were updated to return not just the detected tool, but also a string indicating
the reason for the detection. The logging statements were updated to include
this reason.
A regular class for the detection result (vs
Data) was chosen for Ruby compatibility.Automated Tests
No tests were addeed specifically for this logging change.
Manual Tests
When running the LSP, you can observe the log messages to see the detection reasons.
