File 0001-range.c-add-subset-superset-methods.patch added Thank you nobu, I came to the same realisation when writing the tests for my attempt at an implementation (patch attached). Please let me know what you think, when you have time. This is my first "proper" MRI patch, so all comments gratefully received! ---------------------------------------- Feature #14473: Add Range#subrange? https://bugs.ruby-lang.org/issues/14473#change-70599 * Author: greggzst (Grzegorz Jakubiak) * Status: Open * Priority: Normal * Assignee: * Target version: ---------------------------------------- Hi there, I'd like to propose a method that returns true when a range that the method gets called on is a subrange of a range passed in as an argument. Example: ~~~ ruby (2..4).subrange?(1...4) => true (-2..2).subrange?(-1..3) => false ~~~ ---Files-------------------------------- 0001-range.c-add-subset-superset-methods.patch (8.84 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
