the syntax of 'case' is:
`case word in [[(] pattern [| pattern] ...) list ;; ] ... esac`
`list` don't have to issue `break`. `break` is normally used to exit a
`for`, `until` or `while` loop.
when saving .rs files under vim
do not fail to run the syntax checker
error: Unrecognized option: 'parse-only'.
due to this commit
953f294ea30253bb5578e3c895d17fcc97c20dce
which removed the deprecated flag --parse-only
This does the bare minimum to make registration of error codes work again. After this patch, every call to `span_err!` with an error code gets that error code validated against a list in that crate and a new tidy script `errorck.py` validates that no error codes are duplicated globally.
There are further improvements to be made yet, detailed in #19624.

The timezone of the server that builds rustc nightlies
appears to be in UTC. From what I can tell, it builds
the nightlies at 0300 UTC, which takes about ~15 minutes.
So, there were a couple options here for which offset to use.
UTC+3 would ensure that you always got the latest rust, but it
would mean the script is broken ~15/20 minutes a day. UTC+4
means users get a stale nightly for 45 minutes, but that feels
okay to me.
Ideally, buildbot would publish the "current" nightly, but
that seems unneeded relative to fixing it for all Timezones
quickly.
Fixes#21270
I added an option to auto-indent method chains to line up along their '.' operators. Like so:
```
let input = io::stdin().readline()
.ok()
.expect("Failed to read line");
```
The old default would indent like so:
```
let input = io::stdin().readme()
.ok()
.expect("Failed to read line");
```
The Rust guide explicitly condones the former, so I thought it would be nice for the emacs mode to support it. It's off by default, you have to set ```rust-indent-method-chain``` to ```t``` via your .emacs or the customize menu
There's only one build-critical path in which perl is used, and it was to do a text replacement trivially achievable with sed(1).
I ported the indenter script because it [appears to be used][indenter], but removed check links because it appears to be entirely out of date.

`x in y` is more Pythonic than `y.find(x) != -1`. I believe it runs quite a bit faster as well (though it's probably not a bottleneck of the Travis builds):
```bash
$ python -m timeit '"abc".find("a") != -1'
1000000 loops, best of 3: 0.218 usec per loop
$ python -m timeit '"a" in "abc"'
10000000 loops, best of 3: 0.0343 usec per loop

rust.nanorc provides syntax highlighting for Rust. An attempt has been made to make the syntax highlighting look good on both dark and light terminals. Issue #21286.
This PR is dedicated to @substars and nano-lovers everywhere.
There are a large number of places that incorrectly refer
to deriving in comments, instead of derives.
If someone could look at src/etc/generate-deriving-span-tests.py,
I'm not sure how those tests were passing before/if they were.

The script is intended as a tool for doing every sort of verifications
amenable to Rustdoc's HTML output. For example, link checkers would go
to this script. It already parses HTML into a document tree form (with
a slight caveat), so future tests can make use of it.
As an example, relevant `rustdoc-*` run-make tests have been updated
to use `htmldocck.py` and got their `verify.sh` removed. In the future
they may go to a dedicated directory with htmldocck running by default.
The detailed explanation of test scripts is provided as a docstring of
htmldocck.

This way installer can work fully in offline mode.
Put pre-downloaded files
(rust-nightly-x86_64-unknown-linux-gnu.tar.gz and
rust-nightly-x86_64-unknown-linux-gnu.tar.gz.sha256)
into the $HOME/.rustup/YYYY-MM-DD directory
as it would be done by script itself.
Specify --save and --date=YYYY-MM-DD when running.
Files will be picked up and used to install in offline mode.
rust-mode.el recently started highlighting keywords that were substrings of identifiers. Identifiers such as `xyz_type` would have `type` highlighted, which isn't normal. This patch re-introduces `_` as a word constituent, so that keywords following a `_` don't get syntax highlighted as keywords. Fixes issue #20422
As per https://github.com/rust-lang/rust/issues/20405. To be more precise, the changes just the processing of enums when the name is "RUST$ENCODED$ENUM$..." so it correctly parses when there is more than one number encoding the location of the field it's looking for to determine state of the enum
