Overview

Helpers shared by the LSP-side listeners. Kept dependency-light so they can be unit tested without booting Ruby LSP.

Class Method Details

.location_from_s(location_string) ⇒ Object

Converts a “path:line” string (1-based line, as returned by Method#source_location) into an Interface::Location (0-based line). The last segment is treated as the line only when it is numeric, so Windows drive letters (“C:/foo.rb:42”) survive the split and a string without a line suffix falls back to line 0.
