This gets CI working again. The problem was basically a mix of a few
silly mistakes:
- Using `include` instead of `rustdoc_include` in several places.
- Having rewritten the listing numbers incorrectly.
Add `reqwest` and `scraper` dependencies to the `trpl` crate. Wrap them
in `trpl` re-exports which keep the API surface low.
Rewrite the whole first section to use `race` along with those `trpl`
re-exports to show a more “real” example of async code right form the
start, including actual concurrency, unlike the previous introduction.
Update 17.03 to account for having introduced `race` already, and update
listing numbers for rewritten 17.01.
The *inclues* for them were fixed already, but not these!
Remove these from the workspace, because they will need to be used as
path dependencies in `rust-lang/rust`, as part of the build, because the
Rust build pipeline invokes mdBook programmatically rather than via
tools built directly, and we really don’t want to muck with publishing
these to crates.io at present. As a result, they cannot be part of this
workspace, because path dependencies do not get built as a crate within
the hosting workspace. Make sure they do not rely on any features other
than the core `mdbook` library.
This does not yet update all the workspace dependencies to be shared
between the listing and note preprocessors; it *only* integrates the
repo histories.
Instead of requiring a bunch of `<span>` wrangling, add a custom tag,
`<Listing>`, whose attributes get rewritten into the desired output
format, using `<figure>` and `<figcaption>` for improved semantic HTML.
Support both a default (nice and fancy) HTML output mode and a “simple”
mode to make it so we get the desired output format for the NoStarch
input files as well.
