2025-12-29[ruby/prism] Optimize ruby visitorEarlopain
`compact_child_nodes` allocates an array. We can skip that step by simply yielding the nodes. Benchmark for visiting the rails codebase: ```rb require "prism" require "benchmark/ips" files = Dir.glob("../rails/**/*.rb") results = files.map { Prism.parse_file(it) } visitor = Prism::Visitor.new Benchmark.ips do |x| x.config(warmup: 3, time: 10) x.report do results.each do visitor.visit(it.value) end end end RubyVM::YJIT.enable Benchmark.ips do |x| x.config(warmup: 3, time: 10) x.report do results.each do visitor.visit(it.value) end end end ``` Before: ``` ruby 3.4.8 (2025-12-17 revision https://github.com/ruby/prism/commit/995b59f666) +PRISM [x86_64-linux] Warming up -------------------------------------- 1.000 i/100ms Calculating ------------------------------------- 2.691 (± 0.0%) i/s (371.55 ms/i) - 27.000 in 10.089422s ruby 3.4.8 (2025-12-17 revision https://github.com/ruby/prism/commit/995b59f666) +YJIT +PRISM [x86_64-linux] Warming up -------------------------------------- 1.000 i/100ms Calculating ------------------------------------- 7.278 (±13.7%) i/s (137.39 ms/i) - 70.000 in 10.071568s ``` After: ``` ruby 3.4.8 (2025-12-17 revision https://github.com/ruby/prism/commit/995b59f666) +PRISM [x86_64-linux] Warming up -------------------------------------- 1.000 i/100ms Calculating ------------------------------------- 3.429 (± 0.0%) i/s (291.65 ms/i) - 35.000 in 10.208580s ruby 3.4.8 (2025-12-17 revision https://github.com/ruby/prism/commit/995b59f666) +YJIT +PRISM [x86_64-linux] Warming up -------------------------------------- 1.000 i/100ms Calculating ------------------------------------- 16.815 (± 0.0%) i/s (59.47 ms/i) - 169.000 in 10.054668s ``` ~21% faster on the interpreter, ~56% with YJIT https://github.com/ruby/prism/commit/bf631750cf

2024-05-03[ruby/prism] Change ConstantPathNode#child to ConstantPathNode#{name,name_loc}Kevin Newton
This has been requested for a long time, and I'm finally doing it now. Unfortunately this is a breaking change for all of the APIs. I've added in a Ruby method for `#child` that is deprecated so that existing usage doesn't break, but for everyone else this is going to be a bit of a pain. https://github.com/ruby/prism/commit/9cbe74464e
