From: "naruse (Yui NARUSE) via ruby-core" Date: 2024-02-15T00:57:28+00:00 Subject: [ruby-core:116763] [Ruby master Misc#20238] Use prism for mk_builtin_loader.rb Issue #20238 has been updated by naruse (Yui NARUSE). I think there is a risk to use syntax which is not released yet. If the syntax is reverted by some reason, mk_builtin_loader.rb also needs to be also fixed. > We should try making a small C program using Prism to achieve this. If it turns out to be too complicated, we'll revisit the discussion. I doubt this idea even if the initial implementation of it is simple. I'm afraid that it becomes more complex over the years. I think it should use latest stable Ruby as BASERUBY instead. ---------------------------------------- Misc #20238: Use prism for mk_builtin_loader.rb https://bugs.ruby-lang.org/issues/20238#change-106786 * Author: kddnewton (Kevin Newton) * Status: Open * Priority: Normal ---------------------------------------- I would like to propose that we use prism for mk_builtin_loader.rb. Right now the Ruby syntax that you can use in builtin classes is restricted to the base Ruby version (2.7). This means you can't use a lot of the nicer syntax that Ruby has shipped in the last couple of years. If we switch to using prism to parse the builtin files instead of using ripper, then we can always use the latest version of Ruby syntax.

The approach for the PR is taken from how RJIT bindgen works. -- https://bugs.ruby-lang.org/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
