Sorry but I really don't like it. XD So the changes look good, but do we really want to have this?

What don't you like about it? I think it looks better and is easier to read, and it also will be more consistent with other docs that manually use smart punctuation characters. If we're going to be using a serifed font (which is what we use), I think it looks really weird to have non-smart punctuation.

I don't have a strong preference one way or another, they look pretty similar to me. I do think it makes sense to use smart quotes if we're using serif fonts.

(For the next reviewer: the difference in the first example is for "Safe Rust can't cause undefined behavior", it took me a while to find it.)

Actually there are two other places, both in the second paragraph from the top. There’s an apostrophe and an en dash.

Maybe some other from @rust-lang/docs-rs might have opinions in here?

I like it, assuming there's very few false replacements the correct quote/apostrophes look much better to me.

The en-dash usage there is wrong though, that should be an em-dash:

but also unsafe fn—see below).

🎉

The en-dash usage there is wrong though, that should be an em-dash:

Actually I believe it is correct. Two dashes triggers an en dash and three dashes triggers an em dash. And TMK “ – “ and “—“ are considered equivalent, just stylistic choices. (E.g. I read a book about typography that used en dashes surrounded by spaces just like these docs.)

Well, in case it's approved, please also add documentation about this in the rustdoc book then.

Actually, is it necessary to document this? It's purely a display thing -- e.g. we don't (TMK) have docs about the particular way search results are rendered.

Does this cause smart quotes in code blocks? It would be good to have a test for that case specifically so that if we change anything here, it doesn't regress in the future.

Actually, is it necessary to document this? It's purely a display thing -- e.g. we don't (TMK) have docs about the particular way search results are rendered.

IMHO, people who care about writing docs will care how they look. Documenting this seems important. For example, I would go actually put "real" em dashes in if I wasn't sure that the double hyphen wasn't guaranteed to turn into one.

What is this waiting on? I think smart quotes are a useful addition. @camelid can you update the documentation in src/doc/rustdoc/src/how-to-write-documentation.md?

Is it normal that the closing double quote is actually a triple quote? 😆

Nemo157 commented Feb 8, 2021

punct' is a short-hand for punctuation, so yes in this case it is normal.

camelid commented Feb 8, 2021

Yeah, I try to exercise some edge cases in that test, so in the source I have an apostrophe followed by a double quote. There's no "triple quote" there :)

Apparently `"foo\""` has different behavior from `'foo\''` in Python
shlex. See the [discussion on Zulip][z] for more.

I suppose I wasn’t thinking in specifics, but I guess we don’t guarantee that the output of rustdoc is stable to that degree. 🤷

Yeah, it's just a UI change. But it could be worth adding to relnotes to draw attention to it.

wip-sync pushed a commit to NetBSD/pkgsrc-wip that referenced this pull request May 9, 2021
Package changes:
 * bump bootstraps to 1.51.0.
 * adjust patches and cargo checksums as required
 * 1.51 failed to build natively on 32-bit armv7, there is hope
   that this is fixed with 1.52.  (1.51 can be built with netbsd32
   emulation on a aarch64 system).

Upsteream changes:

Version 1.52.0 (2021-05-06)
============================

Language
--------
- [Added the `unsafe_op_in_unsafe_fn` lint, which checks whether the unsafe
  code in an `unsafe fn` is wrapped in a `unsafe` block.][79208] This lint
  is allowed by default, and may become a warning or hard error in a
  future edition.
- [You can now cast mutable references to arrays to a pointer of the same
  type as the element.][81479]

Compiler
--------
- [Upgraded the default LLVM to LLVM 12.][81451]

Added tier 3\* support for the following targets.

- [`s390x-unknown-linux-musl`][82166]
- [`riscv32gc-unknown-linux-musl` & `riscv64gc-unknown-linux-musl`][82202]
- [`powerpc-unknown-openbsd`][82733]

\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.

Libraries
---------
- [`OsString` now implements `Extend` and `FromIterator`.][82121]
- [`cmp::Reverse` now has `#[repr(transparent)]` representation.][81879]
- [`Arc<impl Error>` now implements `error::Error`.][80553]
- [All integer division and remainder operations are now `const`.][80962]

Stabilised APIs
-------------
- [`Arguments::as_str`]
- [`char::MAX`]
- [`char::REPLACEMENT_CHARACTER`]
- [`char::UNICODE_VERSION`]
- [`char::decode_utf16`]
- [`char::from_digit`]
- [`char::from_u32_unchecked`]
- [`char::from_u32`]
- [`slice::partition_point`]
- [`str::rsplit_once`]
- [`str::split_once`]

The following previously stable APIs are now `const`.

- [`char::len_utf8`]
- [`char::len_utf16`]
- [`char::to_ascii_uppercase`]
- [`char::to_ascii_lowercase`]
- [`char::eq_ignore_ascii_case`]
- [`u8::to_ascii_uppercase`]
- [`u8::to_ascii_lowercase`]
- [`u8::eq_ignore_ascii_case`]

Rustdoc
-------
- [Rustdoc lints are now treated as a tool lint, meaning that lints are
  now prefixed with `rustdoc::`
  (e.g. `#[warn(rustdoc::non_autolinks)]`).][80527]

  Using the old style is still allowed, and will become a warning in
  a future release.
- [Rustdoc now supports argument files.][82261]
- [Rustdoc now generates smart punctuation for documentation.][79423]
- [You can now use "task lists" in Rustdoc Markdown.][81766] E.g.
  ```markdown
  - [x] Complete
  - [ ] Todo
  ```

Misc
----
- [You can now pass multiple filters to tests.][81356] E.g.
  `cargo test -- foo bar` will run all tests that match `foo` and `bar`.
- [Rustup now distributes PDB symbols for the `std` library on Windows,
  allowing you to see `std` symbols when debugging.][82218]

Internal Only
-------------
These changes provide no direct user facing benefits, but represent significant
improvements to the internals and overall performance of rustc and
related tools.

- [Check the result cache before the DepGraph when ensuring queries][81855]
- [Try fast_reject::simplify_type in coherence before doing full check][81744]
- [Only store a LocalDefId in some HIR nodes][81611]
- [Store HIR attributes in a side table][79519]

Compatibility Notes
-------------------
- [Cargo build scripts are now forbidden from setting `RUSTC_BOOTSTRAP`.]
  [cargo/9181]
- [Removed support for the `x86_64-rumprun-netbsd` target.][82594]
- [Deprecated the `x86_64-sun-solaris` target in favor of `x86_64-pc-solaris`.]
  [82216]
- [Rustdoc now only accepts `,`, ` `, and `\t` as delimiters for specifying
  languages in code blocks.][78429]
- [Rustc now catches more cases of `pub_use_of_private_extern_crate`][80763]
- [Changes in how proc macros handle whitespace may lead to panics when used
  with older `proc-macro-hack` versions. A `cargo update` should be sufficient
  to fix this in all cases.][84136]

Version 1.52.1 (2021-05-10)
============================

This release disables incremental compilation, unless the user has explicitly
opted in via the newly added RUSTC_FORCE_INCREMENTAL=1 environment variable.

This is due to the widespread, and frequently occuring, breakage encountered by
Rust users due to newly enabled incremental verification in 1.52.0. Notably,
Rust users **should** upgrade to 1.52.0 or 1.52.1: the bugs that are detected by
newly added incremental verification are still present in past stable versions,
and are not yet fixed on any channel. These bugs can lead to miscompilation of
Rust binaries.

These problems only affect incremental builds, so release builds with Cargo
should not be affected unless the user has explicitly opted into incremental.
Debug and check builds are affected.

See [84970] for more details.
