rustdoc: get back missing crate-name when --playground-url is used #37911
Conversation

Thanks for the PR, but could you describe what the bug is and how this is fixing it? |
|
@alexcrichton I've updated the description of the PR. Thank you! |
|
My concerns from the previous PR still apply #37763 (review). At the very least this feature needs tests. |
|
This pr simply fixes a bug found in previous pr. |
|
Yeah I do agree that if we're fixing bugs it's best if we have some tests for this. Could some tests be added to |
|
Ok, I'll try to add some tests. Maybe need a little more time. |
|
@liigo you should be able to do something like https://github.com/rust-lang/rust/blob/master/src/test/rustdoc/playground.rs but with @alexcrichton shouldn't new command line options for rustdoc at least start out as unstable? |
|
Thank you! |
|
Ah yes actually I forgot that we had unstable options in rustdoc now. Can we make this an unstable option at the same time? |
|
@alexcrichton Yes, Will do. |
|
Done. r? @alexcrichton |

rustdoc: get back missing crate-name when --playground-url is used follow up PR #37763 r? @alexcrichton (since you r+ed to #37763 ) ---- Edit: When `#![doc(html_playground_url="")]` is used, the current crate name is saved to `PLAYGROUND`, so rustdoc may generate `extern crate NAME;` into code snips automatically. But when `--playground-url` was introduced in PR #37763, I forgot saving crate name to `PLAYGROUND`. This PR fix that. ---- Update: - add test - unstable `--playground-url`
