Rust Playground Integration for Code Blocks

[alex-ozdemir]

A various points in the book there are very pretty formatted blocks of code.

It'd be cool to have a "run" button. Even cooler if it could be optionally disabled on a codeblock-by-codeblock basis. Perhaps disabling it could correlated with some visual cue for "not entirely working".

I'd be happy to tackle this if there's any interest.

This should probably be implemented in mdbook.

Yup, see https://github.com/azerupi/mdBook/issues/29

Hm. This works for me when I build and read the book locally, but when I try to use one of the "play" buttons on any page on http://rust-lang.github.io/book/second-edition, the Running... code block appears but I don't see any ajax requests to the playground happening, nor does Running... ever change to any output. Not sure what's going on....

@carols10cents any specific examples? I just did it for the first one on http://rust-lang.github.io/book/second-edition/ch03-02-data-types.html and it worked for me.

Maybe the playpen was timing out when you tried? I guess you said you did see no ajax request though.

LMAO nevermind. Turns out my privacy badger addon was blocking play.rust-lang.org. If I unblock it, it totally works. So I think this is fixed now!!
