@xsot have you tried emailing shinh about changing the deadline for Distance from x 2 so it's the same as Distance from x? i suppose it could be interesting to see how people react to having time to submit after major spoilers though..

basically, I figured that the method for editing should vary with the language, since a plain text editor doesn't do it for many languages. A piet editor should let you draw codels, a Spiral editor should let you type along any direction, etc.

Alex A.

@MartinBüttner Does he keep it up to date in terms of adding esolangs as they arise?

quintopia

So each language should have its own menus, editor layout, and visual debugger that it loads from a file when you load the program

Martin Büttner

22:32

@quintopia yeah that would be ideal (and I talked to Timwi about it before... he's added some really neat language-specific debugging features and a few language-specific editing tools since then, but the code is still text based)

@AlexA. not that regularly, but he added both Hexagony and Labyrinth and he finished up Mornington Crescent when I started using it.
