[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] Test against parse.y

2025-10-22T17:11:46+00:00

https://github.com/ruby/prism/commit/17a6a19bbae5c8b438a94816ed67c3852547d859 broke ruby/ruby CI
because some tests are only run against parse.y
This will catch that in the future.

[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] Reject argument command call taking a block with more trailing arguments

2025-09-19T16:55:01+00:00

https://bugs.ruby-lang.org/issues/21168#note-5

The added code samples align with `parse.y`, except for `foo(bar baz do end)` which `parse.y` currently rejects but shouldn't.

[ruby/prism] [Bug #17398] Allow `private def hello = puts "Hello"`

2025-09-12T19:00:01+00:00

This was a limitation of parse.y that prism intentionally replicated.

[ruby/prism] Import code samples for Ruby 3.3 from the parser gem

2025-01-12T00:09:05+00:00

Slightly tweaking the import script becaues of backtrace format changes in Ruby 3.4

Most tests pass in all parsers, with only a handful of failures overall
