Issue #20260 has been updated by kddnewton (Kevin Newton). The PR for this work is here: https://github.com/ruby/ruby/pull/9934. ---------------------------------------- Misc #20260: ISEQ flag for prism compiler https://bugs.ruby-lang.org/issues/20260#change-106695 * Author: kddnewton (Kevin Newton) * Status: Open * Priority: Normal ---------------------------------------- In order to support error highlight, there's needs to be a way to tell which compiler generated an instruction sequence (compile.c or prism_compile.c). That's because when the file is reparsed to find the node based on the node id, we need to know which parser to use. We can't look at the current parser because it may have been dumped to binary and the parser/compile pair might not match up to the current running process. I would like to add a flag to `rb_iseq_constant_body` that indicates it came from prism, as well as the `:prism` hash key to the misc hash in the array form of iseqs. This will allow us to determine the source of the iseq from both C and Ruby. Since this is user-facing (albeit from an experimental library that shouldn't be relied upon) I wanted to make sure this way okay before merging. -- https://bugs.ruby-lang.org/
