Here's another one for you, a regex that will match almost any ruby string: github.com/mwnciau/rbla...

Yeah, you're right. I think it would've been much clearer to extract out to a constant, but the /o modifier allows in-place optimisation so that's what I did because it was easier!

The use case for /o is when you're interpolating (constant) regex objects inside other objects. It lets you split out sub-expressions, increasing readability, without a significant performance hit.

The RubyMine plugin might still be a bit rough and ready. Let me know if you have any issues with it.

Really interested in your vision for Herb, particular level 6. You seem to have gone through a similar journey to me, taking inspiration from Heex, whereas I took inspiration from Laravel when I made RBlade: github.com/mwnciau/rblade

There's for sure lots of room for improving templates in Rails.

LSPs seem an order of magnitude easier to implement than adding a templating language natively! I was warned away from trying it. I had a crack: github.com/mwnciau/herb... / plugins.jetbrains.com/plugin/27954...

Happy to hand over/take these down if you'd prefer to keep control over IDE plugins.

Here's a simplified example of what I mean in PHP. Defining the shape of hashes can add a lot of safety when working with JSON, for example.

I recently read "Division by Zero" by Ted Chiang, a short story about an inconsistent mathematical system. You might might like it.

I'd not come across either, but I can see the similarities. The idea came from Laravel's data_get and data_set methods, which I've used in the past.

I find the string freeze/unfreeze modifiers a little surprising. +"0" and -"0" give very different results in some other languages!
