(Expressed another way: make `[[` et al. work with the curly brace at
the end of a line as is standard Rust style, not just at the start is it
is by default in Vim, from K&R style.)
This came out of #11492, where a simpler but less effective technique
was initially proposed; some discussion of the techniques, ways and
means can be found there.
There are still a few caveats:
- Operator-pending mode behaves differently to the standard behaviour:
if inside curly braces, it should delete up to and including the
closing of the outermost curly brace (that doesn't seem to me
consistent with documented behaviour, but it's what it does). Actual
behaviour (the more logical and consistent, in my opinion): up to the
start of the next outermost curly brace.
- With folding enabled (`set fdm=syntax`), `[[` and `]]` do not behave
as they should: the default behaviour treats an entire closed fold as
one line for these purposes while this code does not (I explicitly
`set nofoldenable` in the function—the side-effects are worse with
folds enabled), leading to unexpected behaviour, the worst of which is
`[[` and/or `]]` not working in visual mode on a closed fold (visual
mode keeps it at the extreme end of the region line of the folded
region, so it's always going back to the opening line of that fold and
immediately being shoved back to the end by visual mode).
- `[[` and `]]` are operating inside comments, whereas the standard
behaviour skips comments.
- The viewport position is sometimes changed when it should not be
necessary.
Just like the bare keyword `crate` is highlighted as Error (a little
dubious, actually, given macros), `mod` is invalid after `extern`: it's
obsolete syntax.
Don't try to match line comments inside of a comment block. That makes
no sense and can highlight differently for people who override their
highlights.
Similarly, don't match a doc-comment inside of a comment block. It
shouldn't be highlighted differently unless it's actually a doc-comment
(and nested comments are obviously not doc comments).
Fixes#12307.
Declare a `type SendStr = MaybeOwned<'static>` to ease readibility of
types that needed the old SendStr behavior.
Implement all the traits for MaybeOwned that SendStr used to implement.
`Times::times` was always a second-class loop because it did not support the `break` and `continue` operations. Its playful appeal (which I liked) was then lost after `do` was disabled for closures. It's time to let this one go.

- Removed the `log` keyword;
- Removed keyword duplicates;
- Highlighted `const` as `Error` rather than `StorageClass`; and
- Highlighted all the reserved keywords as `Error` rather than as
`Keyword`.
(As usual, these highlightings can be overridden if desired.)
This fixes a regression introduced in #10793.
Having a colorscheme which highlights Float the same as Number (I
believe most do), I hadn't noticed that having the special case of "5."
floats (which was one of the added features in #10793) last made it take
precedence, and so it was left to @thestinger to notice it.
The regression meant that in `5.0`, the `5.` was a `rustFloat` (linked
by default to `Float`) and the `0` was a `rustDecNumber` (linked by
default to `Number`), and for `5.0f32` the `5.` was a `rustFloat` and
the `0f32` was a second `rustFloat` (and thus appeared correctly, though
for the wrong reason).
- Implement comment nesting (the implementation is quite ugly at present
and is not quite correct; note the big comment in that area).
- Highlight invalid escape sequences as errors.
- Fix up various inconsistencies and incorrectnesses in number
highlighting.
- Update prelude items (``std::io::{Buffer, Writer, Reader, Seek}``).
- Highlight the ``proc`` keyword.
- Remove %-formatting sequence highlighting (a relic of old formatting).
- Don't highlight TODO in strings (it's unconventional).
Previously, `//// foo` and `/*** foo ***/` were accepted as doc comments. This
changes that, so that only `/// foo` and `/** foo ***/` are accepted. This
confuses many newcomers and it seems weird.
Also update the manual for these changes, and modernify the EBNF for comments.
Closes#10638
I added a few and removed a few and corrected a couple, all with
reference to the prelude. It ends up a slightly arbitrary decision
precisely what ends up in and what doesn't, unfortunately.
- Remove highlighting of ``L"..."`` (obsolete syntax)
- Remove backslash at end of line being a line continuation always
(obsolete syntax; this only affects comments, actually)
- Add highlighting for backslash at end of line and leading whitespace
on the following line inside a string (a genuine line continuation)
Sigil highlighting isn't perfect (especially how it handles ``&``) but
after having used it for a week I feel it to be considerably nicer than
nothing. As usual, if you don't like it, you can turn it off easily by
overriding the default highlighting.
Generics are not handled specially; this means that for something like
``S<T>``, the ``<`` and ``>`` are highlighted as operators. For myself,
I like this, and there is no way to make it properly context aware
without expanding the syntax matching enormously.
Also, special characters are highlighted properly in strings/chars, e.g.
``"\x00"`` or ``'\Ufedcba98'`` appropriately.
Note that this is not actually *used* by default; it is a matter of
configuration still, because you might want to:
- Compile all .rs files with `rustc %` (where each can be built itself)
- Compile all .rs files with `rustc some-file.rs` (where you are editing
part of a crate)
- Compile with a different tool, such as `make`. (In this case you might
put a `~/.vim/after/compiler/rustc.vim` to match such cases, set
makeprg and extend errorformat as appropriate. That should probably go
in a different compiler mode, e.g. make-rustc.)
To try using it, `:compiler rustc`. Then, `:make` on a file you would
run `rustc` on will work its magic, invoking rustc. To automate this,
you could have something like `autocmd FileType rust compiler rustc` in
your Vim config.

When it's a lifetime, a single quotation mark shouldn't have a matching
single quotation mark inserted after it, as delimitMate does by default.
Note that this is not without problems; a char literal coming after an
odd number of lifetime markers will have its quotation marks behave a
little strangely. That, however, is not my fault, but delimitMate's:

Indentation now works correctly on subsequent lines of a multi-line
comment, whether there are leaders (` * `) or not. (Formerly it was
incorrectly doing a two-space indent if there was no leader.)
By default, this no longer puts a ` * ` leader on `/*!` comments, as
that appears to be the current convention in the Rust source code, but
that can easily be re-enabled if desired:
let g:rust_bang_comment_leader = 1
This improves things like doc comment handling when you press Enter and
making using `gf` or `<C-W>f` work on a `use x;` statement in the
current directory.
- Add fold support (NOT turned on by default)
- Highlight `::` by default
- Support the common `NOTE` as an important note
- Highlight `assert!` and `fail!` differently
- Don't highlight `deriving(...)` except in `#[...]`
