[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] Rename Ruby 3.5 to Ruby 4.0

2025-11-08T00:22:17+00:00

See https://github.com/ruby/ruby/commit/6d81969b475262aba251e99b518181bdf7c5a523

It leaves the old variant around. RuboCop for examples accesses `Prism::Translation::Parser35`
to test against ruby-head. For now I left these simply as an alias

[ruby/prism] Make error and snapshot tests multi-version aware

2025-10-22T14:50:11+00:00

This one has been on my mind for a while now.

Currently, there are only tests against the latest syntax version.

This changes the snapshot structure as follows:
* Snapshots at their current location are tested against all syntax versions
* Snapshots inside a version folder like "3.3" are tested against all versions starting from that version
* Snapshots inside a version folder like "3.3-4.2" are tested against all versions in the given range.

This makes sure that as new syntax is added, older versions still work as expected.
I also added a few tests for now valid syntax that should be invalid in older versions (and the other way around as well)

These tests run really fast. So even though it does 3x the work for these, I am still able to run the whole test suite in just 11 seconds.

[ruby/prism] Move snapshots

2025-03-27T20:14:36+00:00

This is messing up the CRuby sync, so moving them out of the test
directory will make this easier.

[ruby/prism] Warn when the parser translator receives an incompatible builder class

2025-03-19T21:03:17+00:00

In https://github.com/ruby/prism/pull/3494 I added a bit of code
so that using the new builder doesn't break stuff.
This code can be dropped when it is enforced that builder
is _always_ the correct subclass (and makes future issues like that unlikely).
