Issue #19452 has been updated by janosch-x (Janosch Müller). `TracePoint` also lacks column information AFAICT so it might be worthwhile to consider it in search of a consistent solution. ---------------------------------------- Feature #19452: `Thread::Backtrace::Location` should have column information if possible. https://bugs.ruby-lang.org/issues/19452#change-103245 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal ---------------------------------------- I discussed this with @mame and it would be pretty useful if we could also get the column information from exception backtrace location, even if it was slow. A POC: ```ruby class Thread::Backtrace::Location if defined?(RubyVM::AbstractSyntaxTree) def first_column RubyVM::AbstractSyntaxTree.of(self, keep_script_lines: true).first_column end else def first_column raise NotImplementedError end end end ``` It would be good to have a standard interface, so we follow the same interface as https://bugs.ruby-lang.org/issues/19451 and vice versa where it makes sense. I'll investigate it. -- https://bugs.ruby-lang.org/
