A runtime error I encountered while playing around in the june version:

1. enter a conditional like if x then y else z
2. remove then, so it becomes if x|y else z
3. enter a space and move left to make if x| y else z
4. attempt to enter then
5. observe runtime error:

Async_kernel: Unhandled exception (Failure "impossible: bin encountered empty or singleton stack")

And maybe this is a separate bug, but if you go
4. enter then (without a leading space) to make if x|then y else z
5. separate x from then with a space to make if x |then y else z
6. observe that the then is not recognized as a keyword and remains in the backpack

Hi! I was just playing around with the June 2022 version after the FoC meetup and thought I should report a bug I encountered.

First, I entered the expression let fact = x in a, then I remove the = and it becomes let factx in a. If I then insert a space between fact and x and move the cursor next to the x (so it becomes let fact |x in a with | as the cursor) and I try to insert a =, the = is not inserted and I get an exception:

(Exception
   "(Failure \"impossible: bin encountered empty or singleton stack\")")

I also just want to say that I love the concept and it looks gorgeous. I hope you manage to make this into a robust prototype!

I wanted to create an issue and just say what a masterpiece this one is. Having the honor to be the first like and first issue was amazing so let me make the first issue about saying how awesome this project is! What a job!

Hi everyone.

idea

1. I believe that tylr's graphical interface is very innovative. What I'm going to talk about here is different, unique and strange.
2. Lately I've been getting involved a lot with open projects - of all types and sizes. And of different types of audience and purpose or scope.
3. One thing that has always caught my attention is version control: git.

why?

1. I use git version control a lot to manage each of these open projects that I talked about initially, but... one of my problems with git is its complex commands for an end user like me. There are no great GUIs for git. I'm thinking of using tylr for git.
2. One of the things that caught my attention is the idea of how tylr is made. One crazy idea I had was to create a git client with a block interface instead of typing commands.

how?

1. In my idea it would be possible to use git as a block with tylr.
2. I've been developing an idea of a version control made from blocks of code and related to a database.
3. My idea is to make life easier for developers by creating something as innovative as git. One of the ideas that I consider to be good is to use the graphical interface of tylr to manage the version control.

example?

img-description: My idea would be to have positional version control, with that in mind we have a versioned dictionary of words in any programming language for any open project. So, as we can see in the conceptual image we have a code block in tylr to control the software version.

source-code
Here we have a positional version control generated by tylr - we know words or code snippet has been removed, added.

What do you think of this idea? What do you think of this idea of ​​a command-block interface?

Hi!

tylr looks very interesting. I came Jack Rusher's talk at Strange Loop 2022 (https://www.youtube.com/watch?v=8Ab3ArE8W3s).

Is there a technical dive somewhere into why and how it works? In terms of the algorithm and any generalizations that came from designing it, not necessarily this particular implementation.

I'm not an expert in this area, so can't reference specific terms, but I'd still be very interested in such a write-up.

Example of what I'd be looking for: How plausible would it be to design something like tylr for different existing languages? For some, more difficult than others; or maybe it needs some special grammar properties to work at all. What does that entail, etc.
