* assert_raise's 2nd argument is the failure message,
  shown when the expected exception is not raised.
  It's not the expected message.

[ruby/prism] Fix `%Q` with newline delimiter and heredoc interpolation

2025-12-04T14:50:46+00:00

The lexer did not jump to the `heredoc_end`, causing the heredoc end delimiter
to be parsed twice.

Normally the heredocs get flushed when a newline is encountered. But because
the newline is part of the string delimiter, that codepath is not taken.

Fixes [Bug #21758]

[ruby/prism] Clean up test excludes

2025-12-02T16:20:43+00:00

Mostly not having to list version-specific excludes when testing against ripper/parse.y

Also don't test new syntax additions against the parser gems. The version support
for them may (or may not) be expanded but we shouldn't bother while the ruby version
hasn't even released yet.
(ruby_parser translation is not versioned, so let as is for now)

I also removed excludes that have since been implemented by parse.y

[ruby/prism] Update unicode tables to match that of CRuby

2025-11-30T04:24:06+00:00

The unicode version has been updated upstream, which means new
codepoints mapped to alpha/alnum/isupper flags. We need to update
our tables to match.

I'm purposefully not adding a version check here, since that is
such a large amount of code. It's possible that we could include
different tables depending on a macro (like UNICODE_VERSION) or
something to that effect, but it's such a minimal impact on the
running of the actual parser that I don't think it's necessary.

[ruby/prism] Fully destroy call operator write arguments

2025-11-30T02:08:41+00:00

If we are about to delete a call operator write argument, it needs
to be removed from the list of block exits as well.

[ruby/prism] Handle invalid string pattern key

2025-11-29T19:47:45+00:00

When a pattern match is using a string as a hash pattern key and is
using it incorrectly, we were previously assuming it was a symbol.
In the case of an error, that's not the case. So we need to add a
missing node in this case.
