Subject: [ruby-core:113602] [Ruby master Feature#19452] `Thread::Backtrace::Location` should have column information if possible.

Issue #19452 has been updated by janosch-x (Janosch M�ller).





`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

* 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.
