Issue #19458 has been updated by rubyFeedback (robert heiler). I have no particularly strong opinion either way. But I wanted to comment on zverok's statement:
[...] use the possibility to "tag" strings, and if Ruby will give the access to this "tag", it might find many good usages.
I agree somwhat with that opinion too. For instance, I also suggested to propose an extension to case/when "interfaces" where we can not only access all case/when entries in a given method (perhaps only for non-private methods), and merge different case/when entries, as well as adding methods such as .to_h or .to_hash to convert it to a hash, and/or to a proc object, and .call() on it. My original use case for this, several years ago, was to be able to autogenerated tab-completion for shells such as bash and zsh. So that I can know all entries in a case/when menu. For instance: case x when 'a','b','c' 'foobar' # all three match to foobar, similar to a Hash where the # three keys 'a','b' and 'c' would point to 'foobar' end Since then case/when menu got even better support - see pattern matching. Anyway - making a good proposal that is not-trivial, is quite difficult actually, so I kind of dropped it, hoping that someone else may find the motivation to do a good proposal here one day. :D So, to come to this issue - I think if you look at it from an extended point of view, then being able to know associated use cases could indeed be interesting, so on that topic I concur with zverok. That does not mean I am in favour of the suggestion here, or in disfavour - I just think it may indeed be worthy to explore use case here. I have not had a huge need to use ERB per se, but I do happen to read in a .md file ---------------------------------------- Feature #19458: Expose HEREDOC identifier https://bugs.ruby-lang.org/issues/19458#change-102062 * Author: joelhawksley (Joel Hawksley) * Status: Open * Priority: Normal ---------------------------------------- I’d like to have access to the HEREDOC identifier. In the ViewComponent framework I help maintain, we added a method to declare a template as such: ```ruby class Component erb_template <<~ERB <h1>Hello, <%= @name %>!</h1> ERB end ``` I'd prefer to be able to write: ```ruby class Component template <<~ERB <h1>Hello, <%= @name %>!</h1> ERB end ``` And be able to see that the argument passed to `.template` was from a HEREDOC with an `ERB` identifier, which would allow me to use the correct template handler to compile the template. I could see this being implemented: 1) As a new property of String, such as `identifier` or `heredoc_identifier`. 2) By having HEREDOCs return a subclass of String that includes an `identifier` property. I'd be happy to work on implementing this change. ---Files-------------------------------- clipboard-202302251947-5owjc.png (16.4 KB) -- https://bugs.ruby-lang.org/
