Overview

Renders browser frames as Ruby backtrace lines.

Error backends parse backtraces with a Ruby-shaped regex — roughly

/^((?:[a-zA-Z]:)?[^:]+):(\d+)(?::in [`']([^']+)')?$/

so a frame written as "/app/javascript/foo.js:42:in `connect'" is understood, linked to its source and (when the path is under the project root) treated as application code. Two constraints follow from that regex: the file part can't contain a colon, and a trailing ":column" makes the whole line fail to match — hence columns are dropped here and carried in the report context instead.

Frames we can't resolve to a source file are emitted verbatim; backends fall back to showing the unparsed line, so nothing is lost.
