Educational computer programming environment using Haskell
This has to wait on GHCJS to catch up to 8.6, but I'm creating this issue to document the plan. ## The current state `codeworld-base` implements a polymorphic `(==) ::...
One thing that would be extremely useful for embedded editors (see #1248) is defining regions of the source that should be considered editable, and others that should be considered fixed....
It's possible to embed CodeWorld into an iframe in a larger page. However, it's not a great experience currently. The page loads a sidebar with currently open projects that you...

FYI @alphalambda I think I'm hopeful that `randomDrawingOf` and `guiDrawingOf` belong in the core CodeWorld API. They make for a nice transition between animations and more general parameterized drawings. I'd...
Documenting an idea that came up in discussion with @alphalambda. In some cases, one wants to give students a different prelude: either to add more primitives, to restrict them, or...
**Program:** https://code.world/#PYMH5Ap8SMi2ipXxb7WF_Iw **Comment:** Didn't tell me how to fix **Message:** program.hs:7:17-53: error: • Couldn't match expected type (Picture, Number, Number) with actual type Picture
Many of the teacher-facing features of CodeWorld are not well documented. This includes: 1. The requirements checker, useful for additional feedback. 2. Import by hash, useful for designed exercises with...
Inspired by @alphalambda's discussion of handling state at NY Haskell. We could add these to CodeWorld: ``` haskell onKeyPress :: (Text, state -> state) -> ((state, Event) -> state) onAnyKeyPress...
