The struct and module doc comments are reformulated. The `execute`
method's documentation are put up to date, and failure information
is added. A test is also added to address the possible failure.
```test_harness
#[test]
fn foo() {}
```
will now compile and run the tests, rather than just ignoring & stripping them (i.e. it is as if `--test` was passed).
Also, the specific example in https://github.com/rust-lang/rust/issues/12242 was fixed (but that issue is broader than that example).
rustdoc now supports compiling things with `--test` so the examples in
this guide can be compiled & tested properly (revealing a few issues &
out-dated behaviours).
Also, reword an example to be clearer, cc #12242.
Continuing from #15012, this makes four changes to the `rustdoc` static files.
- Change the placeholder text of the search bar to `Click or press 'S' to search, '?' for more options...` to make keyboard hotkeys more apparent (capitalizing the `S` to match the help text).
- Change the `main.js` file to use browser-normalized key codes (`e.which`, from `jQuery`), instead of `e.keyCode`.
- Change the key code for `?` to be the correct `191` instead of `188`, so that the hotkey works to bring up search information.
- Change the search information to display `tab` and `shift+tab` instead of `up` and `down`, as those do not yet work outside of Firefox (see #15011). Also, adjust the height so it does not cut off the help text.
<s>I've also opened up #15038 about the non-functional `up` and `down` functionality, although this does nothing to fix it.</s>
This test was added long time ago and marked as ignored.
The same test was added later in #8485 as run-fail/issue-3907.rs,
but the old one was not deleted.
Updated search bar to match help text.
Used correct, normalized hotkeys in search.
Updated shortcut menu with working shortcuts (tabs).
Changed height of search help.
This adds the `test_harness` directive that runs a code block using the
test runner, to allow for `#[test]` items to be demonstrated and still
tested (currently they are just stripped and not even compiled, let
alone run).
The lexer already ignores CRLF in between tokens, but it doesn't
properly handle carriage returns inside strings and doc comments. Teach
it to treat CRLF as LF inside these tokens, and to disallow carriage
returns that are not followed by linefeeds. This includes handling an
escaped CRLF inside a regular string token the same way it handles an
escaped LF.
This is technically a breaking change, as bare carriage returns are no
longer allowed, and CRLF sequences are now treated as LF inside strings
and doc comments, but it's very unlikely to actually affect any
real-world code.
This change is necessary to have Rust code compile on Windows the same
way it does on Unix. The mozilla/rust repository explicitly sets eol=lf
for Rust source files, but other Rust repositories don't. Notably,
rust-http cannot be compiled on Windows without converting the CRLF line
endings back to LF.

This creates a stability baseline for all crates that we distribute that are not `std`. In general, all library code must start as experimental and progress in stages to become stable.

Also add a new snapshot, to be able to use the new b"foo" syntax.
The src/etc/2014-06-rewrite-bytes-macros.py script automatically
rewrites `bytes!()` invocations into byte string literals.
Pass it filenames as arguments to generate a diff that you can inspect,
or `--apply` followed by filenames to apply the changes in place.
Diffs can be piped into `tip` or `pygmentize -l diff` for coloring.
Fixes a codegen bug which generates illegal non-terminated LLVM block
when there are wildcard pattern with guard and enum patterns in a match
expression. Also refactors the code a little.

This patch consolidates and cleans up the task spawning APIs:
* Removes the problematic `future_result` method from `std::task::TaskBuilder`,
and adds a `try_future` that both spawns the task and returns a future
representing its eventual result (or failure).
* Removes the public `opts` field from `TaskBuilder`, instead adding appropriate
builder methods to configure the task.
* Adds extension traits to libgreen and libnative that add methods to
`TaskBuilder` for spawning the task as a green or native thread.
Previously, there was no way to benefit from the `TaskBuilder` functionality and
also set the scheduler to spawn within.
With this change, all task spawning scenarios are supported through the
`TaskBuilder` interface.
Closes#3725.

Define a command :Run to compile and run the current file. This supports
unnamed buffers (by writing to a temporary file). See the comment above
the command definition for notes on usage.
Define <D-r> and <D-R> mappings for :Run to make it easier to invoke in
MacVim.
Define a command :Expand to display the --pretty expanded output for the
current file. This can be configured to use different pretty types. See
the comment above the command definition for notes on usage.
Create an autoload file and put function definitions there to speed up
load time.
The nightly builds on linux have been failing over the past few days due to a
malformed LD_LIBRARY_PATH. It appears that the underlying cause is that one of
the tests, dep-info-custom, recursively invokes make but the RUSTC variable
passed down has the string "$LD_LIBRARY_PATH". This is intended to read the
host's original LD_LIBRARY_PATH, but it appears that the makefile is eagerly
expanding the "$L" to nothing, causing the original host's LD_LIBRARY_PATH to be
ignored.
This fix removes passing the string "$LD_LIBRARY_PATH" and rather expands it
eagerly to ensure that escaping doesn't happen at a later stage. I'm still not
entirely sure why the makefile is interpreting the dollar as a variable, but
this seems to fix the issue.

Teach StringReader how to emit errors for arbitrary spans, so we don't
need to modify peek_span. This allows for emitting errors without having
a &mut borrow of the StringReader.
