Show HN: An interactive debugger for the Mornington Crescent esolang

https://codeberg.org/Two9A/mcresc
3•Two9A•1h ago
Originally put together ten years ago, I've migrated this project over to Codeberg and in the process fixed a couple of bugs.

The most glaring issue was that in the intervening years, CORS has become a thing so the Transport for London Tube map can no longer be loaded directly from their site; instead, there's a local copy of the SVG.

I'm happy with where it is at the moment, there might be more small patches in another ten years.
