class SyntaxSuggest::PathnameFromMessage
Converts a SyntaxError
message to a path
Handles the case where the filename has a colon in it such as on a windows file system: github.com/ruby/syntax_suggest/issues/111
Example:
message = "/tmp/scratch:2:in `require_relative': /private/tmp/bad.rb:1: syntax error, unexpected `end' (SyntaxError)" puts PathnameFromMessage.new(message).call.name # => "/tmp/scratch.rb"
