The vim syntax highlighting file had become out of sync with the real prelude.
Lots of Vector -> Slice renames have happened recently.

We shouldn't be setting any settings in the syntax file. Better to put
them in the ftplugin, where they won't be pulled in by :syn-include and
can be cleaned up when changing the filetype.

We shouldn't be setting conceallevel in the syntax file. Besides not
being able to undo this if we switch to another syntax later, it also
interferes with embedding rust in other filetypes (such as markdown).
Instead, set it in the ftplugin, where it belongs.

This leaves the `Share` trait at `std::kinds` via a `#[deprecated]` `pub use`
statement, but the `NoShare` struct is no longer part of `std::kinds::marker`
due to #12660 (the build cannot bootstrap otherwise).
All code referencing the `Share` trait should now reference the `Sync` trait,
and all code referencing the `NoShare` type should now reference the `NoSync`
type. The functionality and meaning of this trait have not changed, only the
naming.
Closes #16281

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.

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.

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.
|
|
g:rust_fold allows folding to be enabled. This lets the user turn on
folding without having to define autocommands.

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;
}
Closes #6515.

This does not yet change the compiler and libraries from `*T` to `*const T` as
it will require a snapshot to do so.

Note that the corresponding RFC, https://github.com/rust-lang/rfcs/pull/68, has not yet been accepted. It was [discussed at the last meeting](https://github.com/rust-lang/rust/wiki/Meeting-weekly-2014-06-10#rfc-pr-68-unsafe-pointers-rename-t-to-const-t) and decided to be accepted, however. I figured I'd get started on the preliminary work for the RFC that will be required regardless.

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.

Attempt to highlight the placement expression in a `box (expr) foo`
expression. Also treat GC as a keyword within the placement expression.
This doesn't work correctly for arbitrary expressions. Notably, this
makes no attempt at balancing delimiters. I believe handling that will
require rewriting the syntax rules to add a region for every pair of
delimiters. That may be a desirable thing to do in the end, because we
can then rewrite our indent rules based on the syntax and get rid of
cindent(), but for the time being, we'll just live with the limitation.
|
|

cindent handles the following case incorrectly:
impl X {
b: int,
//
c: int,
}
if you try and insert a new line after the `c` declaration.
To fix this, fix the get_line_trimmed() function to work properly, and
then extend GetRustIndent to keep searching backwards until it finds a
non-blank line after trimming. This lets it handle the trailing comma
case properly, as if the comment were never there.
Fixes #14041.

This keyword is about to be used much more often than it was a few weeks ago,
it's time to tell editors about the new keyword.
|
|
If an unbalanced [ exists in a string or comment, this should not be
considered when calculating the indent at the top level.
Similarly, when testing for ({/}) to see if we're at the top level to
begin with, strings and comments should be skipped.
|
|
The change in #13600 was incorrect, containing a bad regular expression;
inside an indent function, errors are silently ignored (and the ``~=``
operation will return 0), so it just always failed, causing the cases
that were supposed to be caught to not be caught and making things like
the ``match`` example shown above or struct field definitions regress.
I have fixed the regular expression to what it should have been. This is
still imperfect, of course, not handling cases like where the first
argument to a function is a function call (``foo(bar(),``), but it'll do
for now.

It seems really weird to me when StrSlice and str highlight sanely, but StrBuf doesn't.
I think I added it to the right place.
|
|
|
|
When calling a function, or anything with nested parens,
default to cindent's indent. The least error-prone way I
could think of identifying this is to look for a line
that ends with a ',', as well as a non-zero number of
any character except parens before the comma, and
then an open paren.
This will overlap with the previous rule accounting for
function definitions, but that should be fine because
it is also using cindent.

Summary:
So far, we've used the term POD "Plain Old Data" to refer to types that
can be safely copied. However, this term is not consistent with the
other built-in bounds that use verbs instead. This patch renames the Pod
kind into Copy.
