Issue #19279 has been updated by mame (Yusuke Endoh). TBH, I don't fully understand the need for `Coverage.supported?`. (I thought `RUBY_VERSION > "3.1"` was good enough as I said in https://bugs.ruby-lang.org/issues/19026#note-6.) So I am not sure of the need for `Coverage.supported?(:oneshot_lines)` either. In any case, since it is already in place, I don't see a problem with introducing more `Coverage.supported?(:oneshot_lines)`. ---------------------------------------- Bug #19279: Allow `Coverage.supported?` to recognize oneshot lines mode https://bugs.ruby-lang.org/issues/19279#change-100860 * Author: kevin-j-m (Kevin Murphy) * Status: Open * Priority: Normal * ruby -v: ruby 3.2.0 (2022-12-25 revision a528908271) [x86_64-darwin22] * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- Currently in Ruby 3.2.0, Coverage's new `supported?` method (introduced in https://bugs.ruby-lang.org/issues/19026) does not recognize support for oneshot lines. Given that it is an available mode of coverage, I'm proposing that `Coverage.supported?` report that oneshot lines is supported. Current behavior: ``` bash ~|⇒ ruby -v ruby 3.2.0 (2022-12-25 revision a528908271) [x86_64-darwin22] ~|⇒ irb irb(main):001:0> require "coverage" => true irb(main):002:0> Coverage.supported?(:lines) => true irb(main):003:0> Coverage.supported?(:oneshot_lines) => false ``` -- https://bugs.ruby-lang.org/
