Contributions to Ruby

List of my (zverok aka Victor Shepelev) contributions to discussing/changing of the Ruby programming language. It links to Ruby bug tracker discussions and GitHub PRs of things I’ve contributed and proposed and their current status. Rejected/ignored proposals are eventually removed from the list.

Contributed to discussions

(The cases where I was not an author of initial proposal, but believe my contribution/pushing for solution was significant enough)

• 3.1: IO::Buffer reviews/proposals
• 3.0: Hash#except
• 2.7: Syntax sugar for method reference: seems .: is finally accepted for 2.7 (ugh, reverted)
• 2.5: Kernel#yield_self – I don’t like the name, but for several months pushed for “we should have this method, whatever name you choose” :) Then we renamed it to #then in 2.6

Minor clarifications and bugs

• 3.2 Range#include? inconsistency for beginless String ranges
• 3.1 Necessity of require 'fiber'
• 3.0 Object.clone(freeze: true)
• 2.7 Deprecate Kernel#open provided by open-uri in favor of more explicit URI.open
• 2.7 Time#dst? bug for time with real timezone
• 2.7 IO#set_encoding_by_bom raising on already set encoding
• StringIO#internal_encoding is broken
