Here’s what the Vim manual says in *:syn-include*:
:sy[ntax] include [@{grouplist-name}] {file-name}
All syntax items declared in the included file will have the
"contained" flag added. In addition, if a group list is
specified, all top-level syntax items in the included file will
be added to that list.
We had two rules for `rustModPath`, one `contained` and the other not.
The effect was that the second (now renamed to `rustModPathInUse`) was
being included in the group list, and thus that all identifiers were
being highlighted as `Include`, which is definitely not what we wanted.
This PR adds the LLDB autotests to the debuginfo test suite so I don't have to keep rebasing them locally. They are still disabled by default in `tests.mk`. One of the commits also contains a Python pretty printer which can make LLDB print values with Rust syntax. This was mainly added to deal with output format differences between LLDB versions but you can also use it for your normal LLDB debugging sessions.
```
// The following LLDB commands will load and activate the Rust printers
command script import ./src/etc/lldb_rust_formatters.py
type summary add --no-value --python-function lldb_rust_formatters.print_val -x .* --category Rust
type category enable Rust
```
Expect some rough edges with these, they have not been tested apart from there use in the autotests...
Tweak the text editing settings (softtabstop, textwidth, etc).
Add some settings to turn on folding and colorcolumn.
Add the undo_ftplugin changes that my previous patch forgot.
- Graphemes and GraphemeIndices structs implement iterators over
grapheme clusters analogous to the Chars and CharOffsets for chars in
a string. Iterator and DoubleEndedIterator are available for both.
- tidied up the exports for libunicode. crate root exports are now moved
into more appropriate module locations:
- UnicodeStrSlice, Words, Graphemes, GraphemeIndices are in str module
- UnicodeChar exported from char instead of crate root
- canonical_combining_class is exported from str rather than crate root
Since libunicode's exports have changed, programs that previously relied
on the old export locations will need to change their `use` statements
to reflect the new ones. See above for more information on where the new
exports live.

If ldconfig fails it emits a warning. This is very possible when installing
to a non-system directory, so the warning tries to indicate that it may
not be a problem.

This adds detection of the relevant LD_LIBRARY_PATH-like environment variable
and appropriately sets it when testing whether binaries can run or not.
Additionally, the installation prints a recommended value if one is necessary.

Add libunicode; move unicode functions from core
- created new crate, libunicode, below libstd
- split `Char` trait into `Char` (libcore) and `UnicodeChar` (libunicode)
- Unicode-aware functions now live in libunicode
- `is_alphabetic`, `is_XID_start`, `is_XID_continue`, `is_lowercase`,
`is_uppercase`, `is_whitespace`, `is_alphanumeric`, `is_control`, `is_digit`,
`to_uppercase`, `to_lowercase`
- added `width` method in UnicodeChar trait
- determines printed width of character in columns, or None if it is a non-NULL control character
- takes a boolean argument indicating whether the present context is CJK or not (characters with 'A'mbiguous widths are double-wide in CJK contexts, single-wide otherwise)
- split `StrSlice` into `StrSlice` (libcore) and `UnicodeStrSlice` (libunicode)
- functionality formerly in `StrSlice` that relied upon Unicode functionality from `Char` is now in `UnicodeStrSlice`
- `words`, `is_whitespace`, `is_alphanumeric`, `trim`, `trim_left`, `trim_right`
- also moved `Words` type alias into libunicode because `words` method is in `UnicodeStrSlice`
- unified Unicode tables from libcollections, libcore, and libregex into libunicode
- updated `unicode.py` in `src/etc` to generate aforementioned tables
- generated new tables based on latest Unicode data
- added `UnicodeChar` and `UnicodeStrSlice` traits to prelude
- libunicode is now the collection point for the `std::char` module, combining the libunicode functionality with the `Char` functionality from libcore
- thus, moved doc comment for `char` from `core::char` to `unicode::char`
- libcollections remains the collection point for `std::str`
The Unicode-aware functions that previously lived in the `Char` and `StrSlice` traits are no longer available to programs that only use libcore. To regain use of these methods, include the libunicode crate and `use` the `UnicodeChar` and/or `UnicodeStrSlice` traits:
extern crate unicode;
use unicode::UnicodeChar;
use unicode::UnicodeStrSlice;
use unicode::Words; // if you want to use the words() method
NOTE: this does *not* impact programs that use libstd, since UnicodeChar and UnicodeStrSlice have been added to the prelude.

The latest change to aturon/rust-guidelines states that lines must not
exceed 99 characters. This gets rid of the 80/100 split, so we don't
need to customize colorcolumn amymore.
Setting softtabstop makes <Del> delete 4 spaces as if it were a tab.
Setting textwidth allows comments to be wrapped automatically. It's set
at 80, which is the recommended line length for Rust programs. There are
suggestions that it should be 79, but our current style guide says 80 so
that's what we're matching.
A new setting g:rust_colorcolumn sets colorcolumn as well, to +1,101.
This indicates both the textwidth and the second stricter line length of
100 that our style guide lists.

This will break code that used the old `Index` trait. Change this code
to use the new `Index` traits. For reference, here are their signatures:
pub trait Index<Index,Result> {
fn index<'a>(&'a self, index: &Index) -> &'a Result;
}
pub trait IndexMut<Index,Result> {
fn index_mut<'a>(&'a mut self, index: &Index) -> &'a mut Result;
}

Replace its usage with byte string literals, except in `bytes!()` tests.
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.
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.
This addresses the font lock regression introduced by the earlier pull
request #14818 - attributes are no longer be highligted inside of comments
and strings.
Also add some font lock test infrastructure and some tests for attribute
font locking.
