Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @Eh2406 (or someone else) soon. If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes. Please see the contribution instructions for more information. |

Ok everything looks green and we've got good sign-off so I'm gonna r+, thanks @willcrichton for being patient with this! |

Oh actually I recall that I wanted to test this out before merging. I'm testing this out on the wasmtime repository but currently what I get is: I think that's coming from the Cargo integration here? This project is also slightly wonky where the crate that I'm interested in is |
* Docscrape unit not having dev-dependencies included * Sources for reverse-dependencies generated to the wrong directory * Incorrect features being selected for Docscrape units * Panics from Docscrape-dependent packages not being available

Good call @alexcrichton!! I fixed no fewer than 5 different bugs when testing on the wasmtime repo, including an upstream fix to rustc at rust-lang/rust#90349. See my latest commit for what changed + a summary of changes. This extension now works correctly on the wasmtime repo, e.g.

Nice! Could you add some tests to Cargo for the bugs you found here as well? I think it's fine to add one "interesting" test instead of lots of little tests as well if you'd prefer. Also wow this is really nice. The generated docs I think look really good and having everything automatically slurped up is very appealing. FWIW I ran The only other issue I noticed was that there was a precipitious "cliff" in the execution of
I think we can probably do better here in the long run because crates like |
root units. Only attach Docscrape unit dependencies to workspace Doc units. Add test for scraping examples with complex reverse dependencies.

Ok I added a test. Also re: your concerns, I changed it so:

I think that's pretty reasonable, yeah, a workspace sounds like a good unit for "scrape examples for all crates within here". It looks like there's some more failing tests though? |
|
Ah missed those, just some changed stderr output. Fixed the issue and we should be good now! |

Change rustdoc-scrape-examples to be a target-level configuration This PR addresses issues raised in #9525. Specifically: 1. It enables examples to be scraped from `#[test]` functions, by passing additional flags to Rustdoc to ensure that these functions aren't ignored by rustc. 2. It moves the `arg` from `-Z rustdoc-scrape-examples={arg}` into a target-level configuration that can be added to Cargo.toml. The added test `scrape_examples_configure_target` shows a concrete example. In short, examples will be default scraped from Example and Lib targets. Then the user can enable or disable scraping like so: ```toml [lib] doc-scrape-examples = false [[test]] name = "my_test" doc-scrape-examples = true ```
