Issue #19428 has been updated by naruse (Yui NARUSE). I came up with another idea after I read your proposal: ``` options = { name: "My Nice Options", description: <<|, | This is a cool set of options. | You Can put what you like here. details: <<|, | Some more stuff here... | This will only be indented 2 spaces. | And this 4 spaces. | And this 2 spaces again. | Back to the "left" side. ``` ---------------------------------------- Feature #19428: Adding a "piped heredoc" feature https://bugs.ruby-lang.org/issues/19428#change-101766 * Author: shreeve (Steve Shreeve) * Status: Open * Priority: Normal ---------------------------------------- Hello, I hope this is the correct place to post a small feature request. HEREDOC's are awesome! There are several used within Ruby: ```ruby <<END Have to left justify this END <<-INDENTED Still left justified, but indented ending INDENTED <<~SQUIGGLY I can indent content it will be smartly "dedented/undented". Looks nicer. SQUIGGLY ``` I love using the SQUIGGLY heredoc, which will strip off the minimum whitespace from the front of each line in the heredoc. I often do something like this: ```ruby options = { name: "My Nice Options", description: <<~END This is a cool set of options. You Can put what you like here. END } ``` If you need to continue with the above, you can add a comma after like this: ```ruby options = { name: "My Nice Options", description: <<~END, This is a cool set of options. You Can put what you like here. END details: <<~END, Some more stuff here... This will only be indented 2 spaces. And this 4 spaces. And this 2 spaces again. Back to the "left" side. END } ``` You can even get a little squirrely and use an empty string for a heredoc terminator: ```ruby options = { name: "My Nice Options", description: <<~"", This is a cool set of options. You Can put what you like here. details: <<~"", Some more stuff here... This will only be indented 2 spaces. And this 4 spaces. And this 2 spaces again. Back to the "left" side. } ``` There's one variation that I think would be nice to add, I call it a "piped heredoc". It would essentially work like the squiggly heredoc, but the "terminator" would be the next line that is not indented, and thus not "part of the heredoc". Here's an example: ```ruby options = { name: "My Nice Options", description: <<|, This is a cool set of options. You Can put what you like here. details: <<|, Some more stuff here... This will only be indented 2 spaces. And this 4 spaces. And this 2 spaces again. Back to the "left" side. } ``` Since the leading whitespace is used to tell when the heredoc ends, there is no need for an explicit terminator. You could add one if you'd like to indicate the flavor of the content, for syntax highlighters, but it's value is ignored: ```ruby options = { name: "My Nice Options", description: <<|RUBY, users.each do |user| user.pay_daily_bonus! end details: <<|, Some more stuff here... This will only be indented 2 spaces. And this 4 spaces. And this 2 spaces again. Back to the "left" side. } ``` In the above, the "RUBY" is not really needed, but it is a hint to format that block as Ruby code. This tweak to Ruby's heredocs seems like it could make Ruby syntax easy and fun to read. -- https://bugs.ruby-lang.org/
