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.
|
|
This addresses two problems noted in #14347: the highlight of `#foo]` as an attribute, and the non-highlight of `#[foo = "bar"]`.

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

This commit is the final step in the libstd facade, #13851. The purpose of this
commit is to move libsync underneath the standard library, behind the facade.
This will allow core primitives like channels, queues, and atomics to all live
in the same location.
There were a few notable changes and a few breaking changes as part of this
movement:
* The `Vec` and `String` types are reexported at the top level of libcollections
* The `unreachable!()` macro was copied to libcore
* The `std::rt::thread` module was moved to librustrt, but it is still
reexported at the same location.
* The `std::comm` module was moved to libsync
* The `sync::comm` module was moved under `sync::comm`, and renamed to `duplex`.
It is now a private module with types/functions being reexported under
`sync::comm`. This is a breaking change for any existing users of duplex
streams.
* All concurrent queues/deques were moved directly under libsync. They are also
all marked with #![experimental] for now if they are public.
* The `task_pool` and `future` modules no longer live in libsync, but rather
live under `std::sync`. They will forever live at this location, but they may
move to libsync if the `std::task` module moves as well.

This is part of the ongoing renaming of the equality traits. See #12517 for more
details. All code using Eq/Ord will temporarily need to move to Partial{Eq,Ord}
or the Total{Eq,Ord} traits. The Total traits will soon be renamed to {Eq,Ord}.

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.

Two line summary: Distinguish HOST_RPATH and TARGET_RPATH; added
RPATH_LINK_SEARCH; skip tests broken in stage1; general cleanup.
`HOST_RPATH_VAR$(1)_T_$(2)_H_$(3)` and `TARGET_RPATH_VAR$(1)_T_$(2)_H_$(3)`
both match the format of the old `RPATH_VAR$(1)_T_$(2)_H_$(3)` (which
is still being set the same way that it was before, to one of either
HOST/TARGET depending on what stage we are building). Namely, the format
is <XXX>_RPATH_VAR = "<LD_LIB_PATH_ENVVAR>=<COLON_SEP_PATH_ENTRIES>"
What this commit does:
* Pass both of the (newly introduced) HOST and TARGET rpath setup vars
to `maketest.py`
* Update `maketest.py` to no longer update the LD_LIBRARY_PATH itself
Instead, it passes along the HOST and TARGET rpath setup vars in
environment variables `HOST_RPATH_ENV` and `TARGET_RPATH_ENV`
* Also, pass the current stage number to maketest.py; it in turn
passes it (via an env var) to run-make tests.
This allows the run-make tests to selectively change behavior
(e.g. turn themselves off) to deal with incompatibilities with
e.g. stage1.
* Cleanup: Distinguish in tools.mk between the command to run (`RUN`)
and the file to generate to drive that command (`RUN_BINFILE`). The
main thing this enables is that `RUN` can now setup the
`TARGET_RPATH_ENV` without having to dirty up the runner code in
each of the `run-make` Makefiles.
* Cleanup: Factored out commands to delete dylib/rlib into
REMOVE_DYLIBS/REMOVE_RLIBS.
There were places where we were only calling `rm $(call DYLIB,foo)`
even though we really needed to get rid of the whole glob (at least
based on alex's findings on #13753 that removing the symlink does not
suffice).
Therefore rather than peppering the code with the awkward
`rm $(TMPDIR)/$(call DYLIB_GLOB,foo)`, I instead introduced a common
`REMOVE_DYLIBS` user function that expands into that when called.
After I adding an analogous `REMOVE_RLIBS`, I changed all of the
existing calls that rm dylibs or rlibs to use these routines
instead.
Note that the latter is not a true refactoring since I may have
changed cases where it was our intent to only remove the sym-link.
(But if that is the case, then we need to more deeply investigate
alex's findings on #13753 where the system was still dynamically
loading up the non-symlinked libraries that it finds on the load
path.)
* Added RPATH_LINK_SEARCH command and use it on Linux.
On some platforms, namely Linux, when you have libboot.so that has
its internal rpath set (to e.g. $(ORIGIN)/path/to/HOSTDIR), the
linker still complains when you do the link step and it does not
know where to find libraries that libboot.so depends upon that live
in HOSTDIR (think e.g. librustuv.so).
As far as I can tell, the GNU linker will consult the
LD_LIBRARY_PATH as part of the linking process to find such
libraries. But if you want to be more careful and not override
LD_LIBRARY_PATH for the `gcc` invocation, then you need some other
way to tell the linker where it can find the libraries that
libboot.so needs. The solution to this on Linux is the
`-Wl,-rpath-link` command line option.
However, this command line option does not exist on Mac OS X, (which
appears to be figuring out how to resolve the libboot.dylib
dependency by some other means, perhaps by consulting the rpath
setting within libboot.dylib).
So, in order to abstract over this distinction, I added the
RPATH_LINK_SEARCH macro to the run-make infrastructure and added
calls to it where necessary to get Linux working. On architectures
other than Linux, the macro expands to nothing.
* Disable miscellaneous tests atop stage1.
* An especially interesting instance of the previous bullet point:
Excuse regex from doing rustdoc tests atop stage1.
This was a (nearly-) final step to get `make check-stage1` working
again.
The use of a special-case check for regex here is ugly but is
analogous other similar checks for regex such as the one that landed
in PR #13844.
The way this is written, the user will get a reminder that
doc-crate-regex is being skipped whenever their rules attempt to do
the crate documentation tests. This is deliberate: I want people
running `make check-stage1` to be reminded about which cases are
being skipped. (But if such echo noise is considered offensive, it
can obviously be removed.)
* Got windows working with the above changes.
This portion of the commit is a cleanup revision of the (previously
mentioned on try builds) re-architecting of how the LD_LIBRARY_PATH
setup and extension is handled in order to accommodate Windows' (1.)
use of `$PATH` for that purpose and (2.) use of spaces in `$PATH`
entries (problematic for make and for interoperation with tools at
the shell).
* In addition, since the code has been rearchitected to pass the
HOST_RPATH_DIR/TARGET_RPATH_DIR rather than a whole sh
environment-variable setting command, there is no need to for the
convert_path_spec calls in maketest.py, which in fact were put in
place to placate Windows but were now causing the Windows builds to
fail. Instead we just convert the paths to absolute paths just like
all of the other path arguments.
Also, note for makefile hackers: apparently you cannot quote operands
to `ifeq` in Makefile (or at least, you need to be careful about
adding them, e.g. to only one side).

There's no need to include this specific flag just for android. We can
already deal with what it tries to solve by using -C linker=/path/to/cc
and -C ar=/path/to/ar. The Makefiles for rustc already set this up when
we're crosscompiling.
I did add the flag to compiletest though so it can find gdb. Though, I'm
pretty sure we don't run debuginfo tests on android anyways right now.

The Normalizations iterator has been renamed to Decompositions.
It does not currently include all forms of Unicode normalization,
but only encompasses decompositions.
If implemented recomposition would likely be a separate iterator
which works on the result of this one.

Since rust-top-item-beg-re hasn't been defined yet, using defvar instead of
setq is more appropriate here (and also silences compilation warnings).

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.

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.

Lazy loading with autoload will result in faster startup time for Emacs

Also adds a regex_macros crate, which provides natively compiled
regular expressions with a syntax extension.
Closes #3591.
RFC: 0007-regexps
|
|
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.

This is a bit of an interesting upgrade to LLVM. Upstream LLVM has started using C++11 features, so they require a C++11 compiler to build. I've updated all the bots to have a C++11 compiler, and they appear to be building LLVM successfully:
* Linux bots - I added gcc/g++ 4.7 (good enough)
* Android bots - same as the linux ones
* Mac bots - I installed the most recent command line tools for Lion which gives us clang 3.2, but LLVM wouldn't build unless it was explicitly asked to link to `libc++` instead of `libstdc++`. This involved tweaking `mklldeps.py` and the `configure` script to get things to work out
* Windows bots - mingw-w64 has gcc 4.8.1 which is sufficient for building LLVM (hurray!)
* BSD bots - I updated FreeBSD to 10.0 which brought with it a relevant version of clang.
The largest fallout I've seen so far is that the test suite doesn't work at all on FreeBSD 10. We've already stopped gating on FreeBSD due to #13427 (we used to be on freebsd 9), so I don't think this puts us in too bad of a situation. I will continue to attempt to fix FreeBSD and the breakage on there.
The LLVM update brings with it all of the recently upstreamed LLVM patches. We only have one local patch now which is just an optimization, and isn't required to use upstream LLVM. I want to maintain compatibility with LLVM 3.3 and 3.4 while we can, and this upgrade is keeping us up to date with the 3.5 release. Once 3.5 is release we will in theory no longer require a bundled LLVM.

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.

The goal of the snapshot bots is to produce binaries which can run in as many
locations as possible. Currently we build on Centos 6 for this reason, but with
LLVM's update to C++11, this reduces the number of platforms that we could
possibly run on.
This adds a --enable-llvm-static-stdcpp option to the ./configure script for
Rust which will enable building a librustc with a static dependence on
libstdc++. This normally isn't necessary, but this option can be used on the
snapshot builders in order to continue to make binaries which should be able to
run in as many locations as possible.

Older version of LLVM did not have this flag, so we need to fall back to our
previous library detection when using older versions of LLVM.
