I’m posting this first in the forum to see response before posting as a formal issue. Proposal This is a proposal to introduce a new keyword ends (or endall) as a terminal point to resolve the end of nested loops|conditionals. Why It’s a common code occurrence to have multiple levels of loops an…

Depends on how you set your parsing rules. But again, you can already write syntactically ambiguous code. But also of course, being the smart (non-masochistic) programmer, you’d never intentionally write ambiguous code you intended to use. But maybe if you’re a malicious hacker… But you can alread…

[image] jzakiya: But again, you can already write syntactically ambiguous code. Can you share an example of that?

From your example, there’s no context to evaluate if the if...end statement would be a dangling illegal snippet in that form, so depending on context, the compiler would flag it, or you would (of course) test your code to confirm it was working correctly. I have to go out and live life now. I’ll …

[image] vlazar: In fact now when my eyesight is not so good anymore having end instead of } is helpful for me in terms of being easy to spot the code structure. Haha, yeah, my poor eyesight is the reason I prefer “end” over “}”. it’s just easier to identify than a single character.

Visually it is a good syntactic sugar and I think there is a way to call a strict rule of use (example: last open => first closed). It’s simple to understand. But on the other hand it’s a big source of mistakes. def render(truthy : Bool, show_msg : Bool = false) return "ok" if truthy thing do …

Ok, here are 2 simple rules that control (can make more if necessary). an end statement can only resolve 1 open thing. an ends statement must resolve 2 or more open things. Thus this def render(scene, image, screenWidth, screenHeight) screenHeight.times do |y| screenWidth.times do |x| …

As long as it is not required; personally, I like 1-1 end per start of block.

Yes, I think general best practice is start with encasing a single end for each class|module|method name thing, and use ends for internal structure. But then also use it for long strings of end statements, where it’s clear they are all the same termination point for multiple things (loops|conditio…

[image] jzakiya: you would then know to unambiguously write as this (if this is what you mean). class Foo def bar while true ends if foo while true ends end If ends is used for closing 2+ open “things”, then how would it know to not also close the class in addition to bar an…

I think someone previously proposed introducing endd (two ends), enddd (three ends), etc :-)
