Issue #19690 has been updated by rubyFeedback (robert heiler). One more smaller thing to add: I don't know how colours are used on embedded / constraint system, so anyone with some experience with mruby and embedded system could perhaps also comment on this. Someone using raspberry or arduino, whether they use colours on these systems, and how popular that is there. ---------------------------------------- Feature #19690: Add terminal colorizing gem to stdlib https://bugs.ruby-lang.org/issues/19690#change-103283 * Author: ccmywish (Aoran Zeng) * Status: Open * Priority: Normal ---------------------------------------- Recently the new version of `tracer` gem caught my eye. But I've noticed an anti-DRY pattern. I've noticed that many libs, CLI tools implement their own logic of color support on the terminal. These libs/CLI tools don't explicitly require a gem from RubyGems.org may be because of these reasons: 1. It's very easy to directly monkey patch `String` class to support, such as `bold`, `red`, `blue` 2. The lib is very independent, the author doesn't want any dependency. See: https://github.com/ruby/tracer/blob/master/lib/tracer/color.rb I hope the core team consider adding `official` support for terminal colorizing, because most Ruby developers live on the terminal. If we've added it, all gems/CLI tools developers can easily add simple styles. For example, adding color to `gem` and `bundler` command is attractive. Next door community's `npm` seem much cooler by just using simple colors. Could we coordinate with the gem [rainbow](https://rubygems.org/gems/rainbow)'s author to make it one of the stdlib or bundled gem like `minitest`? -- https://bugs.ruby-lang.org/
