Subject: [ruby-core:112518] [Ruby master Feature#19451] Extract path and line number from SyntaxError?

Issue #19451 has been updated by nobu (Nobuyoshi Nakada).


`SyntaxError` can contain multiple error locations.
I'm trying https://github.com/nobu/ruby/tree/SyntaxError%23diagnostics.

I can't get what "prepend them to backtrace_locations" means.

Feature #19451: Extract path and line number from SyntaxError?

----------------------------------------
There doesn't seem to be any official way to extract the path and line number from a syntax error.

There are two ways I can see us dong this:

- Provide explicit `path` and `line_number` attributes.
- Prepend them to `backtrace_locations`.

The nice thing about the latter approach is that it will just work with existing tools which understand how to highlight code based on backtrace locations.

Maybe we should do both?
