* clang-format: Don't exit with failure on empty files.Daniel Jasper2013-10-081-1/+1
| | | | | | | | | | 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. Thank you! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@192184 91177308-0d34-0410-b5e6-96231b3b80d8

* Moving style option formatting to libFormatEdwin Vane2013-09-301-78/+6
| | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@191666 91177308-0d34-0410-b5e6-96231b3b80d8
* clang-format: Add -assume-filename option for editor integrations.Daniel Jasper2013-09-131-1/+13
| | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@190691 91177308-0d34-0410-b5e6-96231b3b80d8
* Allow _clang-format as alternative to .clang-format config filenameHans Wennborg2013-09-101-0/+10
| | | | | | | | | | | 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. ;] git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@189741 91177308-0d34-0410-b5e6-96231b3b80d8

* Use lexing mode based on FormatStyle.Standard.Alexander Kornienko2013-06-281-3/+4
| | | | | | | | | | | | | | | | | | | | | 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.

* Let clang-format move the cursor appropriately.Daniel Jasper2013-05-211-0/+8
| | | | | | | | | With this patch, clang-format will try to keep the cursor at the original code position in editor integrations (implemented for emacs and vim). This means, after formatting, clang-format will try to keep the cursor on the same character of the same token. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@182373 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | Summary: Adds actual config file reading to the clang-format utility. Configuration file name is .clang-format. It is looked up for each input file in its parent directories starting from immediate one. First found .clang-format file is used. When using standard input, .clang-format is searched starting from the current directory. Added -dump-config option to easily create configuration files.
