Proposal: Extending HereDocs to Support Multiple Languages?— To set the scene here, Matz’s initial reaction to this proposal was “There’s still half a year left until April Fool’s Day.” The idea here is to be able to specify a format/language against heredocs (somewhat as with Markdown code blocks) and to then process those documents dynamically in a custom method. Joke or not, when such an esteemed core team member has an idea, it’s worth checking out, and plenty of jokes have taken off (SOAP.. LINQ..😏)

'How Do I Test X' Is Almost Always Answered with 'By Controlling X'— The sort of insight you probably already have but never put into words before. The next question is, well, how do you control X?

Synvert 1.0: A Tool to Rewrite Ruby Code Automatically— It’s been a few years since we mentioned Synvert, but 1.0 is now here. You write 'snippets' that then dynamically rewrite existing Ruby code (see this flash / redirect_to example from 2017. I gave it a try – it’s a little touchy to set up, but did work.

QUICK BITS:

• Haml 6.0 is finally here, and it's a lot faster than ever before.

• Another Ruby running in the browser via WebAssembly experiment. Lightweight and feels fast.

• Over on Twitter, Justin Searls shared a screenshot from a Slack conversation where he explains 🐦 why he'd recommend against RSpec nowadays.(Gist of the raw text for accessibility.)

• If, somehow, you're still using SVN / Subversion, be aware that svn.ruby-lang.org will shut down in November. It's now Git all the way since the main repo switched to git in 2019.

• Gift Egwuenu has posted the latest monthly update from the RubyGems project.

A Hybrid Docker and Ruby Development Environment— As well as being a handy way to deploy software, containers can be handy for isolating dependencies at development time, so you run Ruby and Rails on your machine dev-style but MySQL and Redis, say, can be managed by Docker.

How to Install (Or Get Rid Of) 'therubyracer' on M1/M2 Macs— therubyracer provides a way to work with the V8 JavaScript runtime from Ruby and has come in very handy over the years, particularly with Rails’ asset pipeline. It doesn’t support modern M1/M2-based Macs though, and.. you no longer probably need it anyway.
