`compact_child_nodes` allocates an array. We can skip that step by simply yielding the nodes.

When there are nested capture variables inside of a pattern match that has an alternation pattern, it is a syntax error. Currently it only adds a syntax error when it is at the top level of the pattern.

2025-10-08[ruby/prism] For these special cases, there exists no optional argument ↵Earlopain
type. Since a endless method is started with `=`, there was ambiguity here. We have to simply reject these in all cases. This adds a new error for the following reason: * `def foo arg = nil` is interpreted as a normal method call with optional `arg` without matching `end` * `def foo *arg = nil; end` is interpreted as a endless method call that has body `nil` with extraneous `end` `def foo *arg = nil` is somewhere inbetween and I don't know how to otherwise indicate the error. Now the second case above also shows the newly added error message. Fixes [Bug #21623] https://github.com/ruby/prism/commit/e1910d4492
2025-10-01[ruby/prism] Add a "LAST" enum field to all flags enumsAaron Patterson
This allows us to use the "last" of the enums in order to make masks, etc. This particular commit uses the call flag's last enum field as an offset so that we can define "private" flags but not accidentally clobber any newly added call node flags. https://github.com/ruby/prism/commit/e71aa980d8

2025-05-23[ruby/prism] Monomorphise visitor methodsUfuk Kayserilioglu
The current implementation of the visitor pattern in Prism uses a single method (`visit_child_nodes`) to handle all node types. This can lead to performance issues since the `node` argument will end up being polymorphic, and will prevent effective use of inline caches, which in CRuby are monomorphic. This commit generates an inlined version of the previous code for each node type, thus making the calls inside visitor methods monomorphic. This should improve performance, especially in cases where the visitor is called frequently. https://github.com/ruby/prism/commit/60d324a701

2025-03-20[ruby/prism] Dynamically register events to dispatchSam Bostock
Instead of requiring the consumer to provide a list of all events which they wish to handle, we can give them to option of dynamically detecting them, by scanning the listener's public methods. This approach is similar to that used by Minitest (scanning for `test_` methods) and Rails generators (running all public methods in the order they are defined). While this is slower than specifying a hard coded list, the penalty is only during registration. There is no change the the behaviour of dispatching the events. https://github.com/ruby/prism/commit/781ebed743
