Really cool. Would be great if each language had an "hello world" example which would populate the fields.

There's a Hello World button now that does just this.

There already is a collection of `Hello, World!`s for every language used in tests, and this feature is planned to be implemented soon.

I agree. In the standard Racket IDE you get automatically the initial

  #lang racket

line, and in some variants for students the equivalent line is hidden. So I had to try a few times until I realized I forgot to add this line. https://tio.run/##K0pMzk4t@a@ck5iXrlAE4Sh5pObk5CuE5xelKP3/Dw...

Another improvement could be to show the debug output automatically. I didn't understand the problem until I read the error message.

BTW Do we really need ~540 bits (~90 chars of base62) to identify permanent link?

Looks like it encodes the whole code instead of storing it somewhere, so yes.

Well in TIO 2.0 that is coming soon it will not be that long.

Great idea!
