TL;DR: The YJIT team wants to explore using Rust to help develop YJIT. The rest of CRuby will continue to build without Rust tools and building YJIT will remain optional. We’re currently exploring the possibility of porting YJIT to Rust and working on a small proof of concept that should be ready next month. The motivation behind this is that we are facing challenges in terms of code maintainabili

I know Sam opened #9113 4 years ago to suggest this but I'm revisiting the topic to see if there's any movement here for Ruby 2.6 or 2.7. I supply a major piece of Ruby infrastructure (Sidekiq) and I keep hearing over and over how Ruby is terrible with memory, a huge memory hog with their Rails apps. My users switch to jemalloc and a miracle occurs: their memory usage drops massively. Some data po

Status changed from Open to RejectedRuby often has two conversion methods for an object, e.g. #to_s and #to_str, #to_i and #to_int, #to_h and #to_hash. The former is used for explicit conversion, the latter is used for implicit conversion (from an object with identical method signature e.g. proxy). Matz.

New to_b method converts strings, symbols, numbers and nil values in a boolean value. to_b method is available on String, Symbol, Numeric, TrueClass, FalseClass and NilClass classes. String¶ Returns true if string is one of t, true, on, y, yes or 1 values. Returns false otherwise. Ignores trailing spaces and letter cases.

We just added Interger#positive? and Interger#negative? to Active Support. I was wondering if we could get that implemented in Ruby itself and searched if it was already requested before to Ruby code. I found that it was requested in #5513, but rejected. Since they were requested with more methods, and I don't know Japanese enough to see if there are technical reasons, I thought to request just th
