encodes the canonical rules for LLVM's style. I noticed this had drifted
quite a bit when cleaning up LLVM, so wanted to clean up Clang as well.

While debating the finer points of file extension matching, we somehow missed
the bigger problem that the current code will match anything starting with the
default or user-specified pattern (e.g. lit.site.cfg.in).
Fix this by doing what find(1) does, implicitly wrapping the pattern with ^$.
llvm-svn: 197608
Summary:
-regex and -iregex both mimic options of the find utility.
Made the default list of extensions case-insensitive, so that it's not only C
and CPP extensions are accepted in upper case.

Add support for more filename extensions based on the list in the clang
plus JavaScript.
Also adds a -regex option so users can override defaults if they have unusual
file extensions or want to format everything in the diff.
Keeping with tradition the flag is modelled on Unix conventions, this time
matching the semantics of find(1).

Sublime Text 2 uses Python 2.6
Sublime Text 3 uses Python 3.3
The `print` function has been available as a __future__ import since
2.6, so use it.

Switch clang-format over to Rewriter::overwriteChangedFiles().
The previous implementation was attempting to stream back directly to the
original file and failing if it was already memory mapped by MemoryBuffer,
an operation unsupported by Windows.
MemoryBuffer generally mmaps files larger than the physical page size so
this will have been difficult to reproduce consistently.
This change also reduces flicker in code editors and IDEs on all platforms
when reformatting in-place.
Note that other incorrect uses of MemoryBuffer exist in LLVM/clang and
will need a similar fix.
A test should be added for Windows when libFormat performance issues are
fixed (it takes longer than a day to format a 1MB file at present!)
llvm-svn: 194250
Summary:
"svn diff|clang-format-diff.py" will just output the diff.
Now it's possible to use:
svn diff|clang-format-diff.py|patch -p0
as an equivalent to:
svn diff|clang-format-diff.py -i
;)

Also let clang-format-diff.py detect errors based on clang-format's
return code. Otherwise messages like "Can't find usable .clang-format,
falling back to LLVM style" can make it fail, which might be undesired.

Patch by Alp Toker. Many thanks!
Original descriptions:
clang-format-diff incorrectly modifies unchanged lines due to an error
in diff parsing.
The unified diff format has a default line change count of 1, and 0 may
be specified to indicate that no lines have been added. This patch
updates the parser to accurately reflect the diff specification.
This also has the benefit of stabilising the operation so it will
produce the same output when run multiple times on the same changeset,
which was previously not the case.
No tests added because this script is not currently tested (though we
should look into that!)
llvm-svn: 191820
The help text for clang-format's -style option and the function that processes
its value is moved to libFormat in this patch. The goal is to enable other
tools that use libFormat and also have a -style option to behave consistently
with clang-format.
llvm-svn: 191666
With -style=file, clang-format now starts to search for a .clang-format
file starting at the file given with -assume-filename if it reads from
stdin. Otherwise, it would start searching from the current directory,
which is not helpful for editor integrations.
Also changed vim, emacs and sublime integrations to actually make use of
this flag.
This fixes llvm.org/PR17072.
llvm-svn: 190691
Dotfiles are impractical on Windows. This makes clang-format search
for the style configuration file as '_clang-format' in addition to
the usual '.clang-format'. This is similar to how VIM searches for
'_vimrc' on Windows.

fallback syntax used when we fail to find a '.clang-format' file. Adjust
variable names appropriately.
Update the editor integration pieces that specify a '-style' option to
specify it as '-style=file'. I left the functionality in place because
even if the preferred method is to use '.clang-format' files, this way
if someone needs to clobber the style in their editor we show how to do
so in these examples.
Also check in a '.clang-format' file for Clang to ensure that separate
checkouts and builds of Clang from LLVM can still get the nice
formatting. =] This unfortunately required nuking the test for the
absence of a '.clang-format' file as now the directory happening to be
under your clang source tree will cause there to always be a file. ;]

After the first operation, the buffer contents has changed and thus all
other operations would be invalid. Executing the operations in reversed
order should fix this.
llvm-svn: 186840
With this fix, only changed regions will be replaced in vim's buffer.
Thereby, marks should mostly be left intact. Furthermore, this is a
better fix for the performance problem in conjunction with
'foldmethod=syntax' (see r186660).
llvm-svn: 186789
The previous line-by-line replacement causes vim to take a long time if
the foldmethod is set to 'syntax'. This should significantly improve
performance in that case.
llvm-svn: 186660
Before, the computed byte range would include the trailing newline.
clang-format on the other hand counts whitespace as belonging to the
following token, so that git-clang-format inadvertendly reformats the
first unmodified line as well.
It is not entirely clear whether clang-format's behavior itself should
be modified, but for now this seems to be a safe change.
llvm-svn: 185423
Summary:
Some valid pre-C++11 constructs change meaning when lexed in C++11
mode, e.g.
#define x(_a) printf("foo"_a);
(example from http://llvm.org/bugs/show_bug.cgi?id=16342). "foo"_a is treated as
a user-defined string literal when parsed in C++11 mode.
In order to deal with this correctly, we need to set lexing mode according to
which standard the code conforms to. We already have a configuration value for
this (FormatStyle.Standard), which seems to be appropriate to use in this case
as well.

The big changes are:
- Deleting Driver/(Arg|Opt)*
- Rewriting includes to llvm/Option/ and re-sorting
- 'using namespace llvm::opt' in clang::driver
- Fixing the autoconf build by adding option everywhere
As discussed in the review, this change includes using directives in
header files. I'll make follow up changes to remove those in favor of
name specifiers.
