codeworld VS reanimate

Code World[1] is a great project that addresses a number of the problems from the article, with an eye towards using Haskell to teach children basic math and programming simultaneously. Code World directly addresses a number of the obstacles outlined in this article:

1. Using an online editor with a rich built-in library removes any toolchain problems.

2. A custom standard library simplifies pedagogically unnecessary details like Foldable

3. The custom standard library also avoids currying (f(a, b) for functions rather than f a b)

4. Custom error messages improve the feedback students get from the compiler

I would highly recommend Code World to anybody looking to teach programming with Haskell. If you want to teach Haskell in a way that fits the existing ecosystem, it's also possible to run Code World without the custom standard library[2].

Alternatively, I'm a big fan of https://code.world which is specifically geared towards learners who want to work up to making simple games. It's kind of a toy, but imo resembles a "real" programming language a lot more than other educational programming languages

Loose connection, but made me remember https://code.world/ uses a Haskell-like functional language to define still pictures, animations, or even games.

I second gloss! It's a bit limited (no sound, fonts, nor even text centering, but you do have support for vector and bitmap graphics, color manipulation, mouse, keyboard, and animations), but it's so, so easy to use that I not only recommend it (or the similar Code World) for anybody's first game, I still use it for my newer games.

Try https://code.world/

Two that I can think of:

- Bootstrap teaches a toned-down version of Racket (i.e. Scheme): https://bootstrapworld.org/materials/spring2021/en-us/course... . It's taught in some schools as well as a comp sci curriculum.

- https://code.world/ teaches using a toned-down version of Haskell. To my knowledge it's not used in schools.

I had the silly 'fromString' error you get when using RebindableSyntax but had forgotten what to do next. Quick Google search and I hit on codeworld #59.

That's a matter of tooling and environment. You can have a look at examples of drawing animations with physics simulation and user input at https://code.world. It's pure Haskell code without any scary abstractions, just functions from state to the next state.

I'm not a user myself, but I understand Lambdabot and mueval depend on it. More generally, anything that executes Haskell code supplied by untrusted users would fit the bill. I don't know if CodeWorld for example allows user-supplied modules, but if it did they'd have to be Safe.

Reanimate sounds almost ideal, with its support for LaTeX. But unfortunately, it is all rendered in batch, not providing for any interactivity.

Is this the discussion you're referring to? https://github.com/reanimate/reanimate/discussions/210

It's actually pretty interesting to read. The author makes a not totally unreasonable argument as for why it uses unsafePerformIO.

Now what I'm really curious about is why the very first example on the site I clicked into the source code for, a simple 59-line example, is using unsafePerformIO. That actually worries me more because it suggests that as a user I might have to use unsafePerformIO. https://github.com/reanimate/reanimate/blob/d4d3898831edb4aa...

Not really dashboard library, but reanimate is a good library for this kind of stuff.

Some other "applications" (if you're not interested in compilers) might be writing shell scripts: https://hackage.haskell.org/package/turtle Or animating stuff: https://github.com/reanimate/reanimate and https://hackage.haskell.org/package/gloss

That aside, it seems that svg-tree doesn’t support filter elements, so I recommend reanimate-svg. You can join the Discord server for Reanimate and ask for help. Good luck.

See also reanimate, a very similar Haskell library: https://reanimate.github.io/

This is very niche, but something I've wanted to do for a while is to generate some cool physics example on the surface of a sphere with https://hackage.haskell.org/package/hamilton, and display it with https://reanimate.github.io/ (using https://hackage.haskell.org/package/linear for the projection)

Hi u/Target_Organic, I wich you a warm welcome! Haskell is often very satisfying to work with, it has a sense of beauty in it. Regarding your questions: 1. I never had big problems about performance. However, I personally place more emphasis about correctness, simplicity and readability of my programs. Performance tuning comes after. 2. For graphic libraries, I know diagrams, Reanimate and Haskell-chart. Since you seems interested by mathematical approach to graphics, I think you will find happiness there. 3. I'm not sure about the AI field. Other, more practical languages such as Python seems to have taken the lead. What is sure for me, that Machine Learning/NN would be nicely describe in Haskell with solid foundations.
