Subject: [ruby-core:119288] [Ruby master Feature#20759] No good API to query which parser is being used
Date: Tue, 24 Sep 2024 18:28:31 +0000 (UTC)	[thread overview]
Message-ID: <redmine.journal-109897.20240924182831.3573@ruby-lang.org> (raw)
In-Reply-To: <redmine.issue-20759.20240924181727.3573@ruby-lang.org>

Issue #20759 has been updated by kddnewton (Kevin Newton).


Note that there is another discussion around retrieving command line options given here: https://bugs.ruby-lang.org/issues/6648.

Feature #20759: No good API to query which parser is being used
https://bugs.ruby-lang.org/issues/20759#change-109897

* Author: luke-gru (Luke Gruber)
* Status: Rejected
----------------------------------------
Right now the best way I found is:

```ruby
parser = RUBY_DESCRIPTION =~ /prism/i ? "prism" : "parse.y"
```

This is useful if you want to invoke a subprocess with the same options given to ruby. ARGV parsing might not work because the option might have been given via RUBYOPT.

Maybe `RubyVM::PARSER` could be set to the current parser, and this value could either be a String or Symbol.
