* clang-format: Improve alignment after 'return'.Daniel Jasper2013-09-301-9/+10
| | | | | | | | | | | | | | | | | Previously, comments, could totally confuse it. Before: return // true if code is one of a or b. code == a || code == b; After: return // true if code is one of a or b. code == a || code == b; llvm-svn: 191654
* Implemented tab usage only for indentation (http://llvm.org/PR17363)Alexander Kornienko2013-09-271-12/+15
| | | | | | | | | | | | | | | | | | | Summary: Changed UseTab to be a enum with three options: Never, Always, ForIndentation (true/false are still supported when reading .clang-format). IndentLevel should currently be propagated correctly for all tokens, except for block comments. Please take a look at the general idea before I start dealing with block comments.

* clang-format: Fix comment formatting bugs in nested blocks.Daniel Jasper2013-09-061-3/+3
| | | | | | | | | | | This fixes two issues: 1) The indent of a line comment was not adapted to the subsequent statement as it would be outside of a nested block. 2) A missing DryRun flag caused actualy breaks to be inserted in overly long comments while trying to come up with the best line breaking decisions. llvm-svn: 190123
* Handle zero-width and double-width characters in string literals and comments.Alexander Kornienko2013-09-051-8/+8
| | | | | | | | | | | | | | | | | | Summary: Count column width instead of the number of code points. This also includes correct handling of tabs inside string literals and comments (with an exception of multiline string literals/comments, where tabs are present before the first escaped newline).

| | | | | | | | | | | | | | | | | | | | | | | | | While this looks kind of nice, it wastes horizontal space and does not seem to be common in the LLVM codebase.

* clang-format: Improve token breaking behavior.Daniel Jasper2013-08-281-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Two changes: * Don't add an extra penalty on breaking the same token multiple times. Generally, we should prefer not to break, but once we break, the normal line breaking penalties apply. * Slightly increase the penalty for breaking comments. In general, the author has put some thought into how to break the comment and we should not overwrite this unnecessarily. With a 40-column column limit, formatting aaaaaa("aaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaa"); Leads to: Before: aaaaaa( "aaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaa " "aaaaaaaaaaaaaaaa"); After: aaaaaa("aaaaaaaaaaaaaaaa " "aaaaaaaaaaaaaaaa " "aaaaaaaaaaaaaaaa"); llvm-svn: 189466
* clang-format: Fix segfault in 'incomplete' macros.Daniel Jasper2013-08-281-3/+4

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously builder-type calls were only correctly recognized in top-level calls. This fixes llvm.org/PR16981.

* clang-format: Handle trailing commas in column layout of braced list.Daniel Jasper2013-08-231-0/+3
| | | | | | | | | | Before, this was causing errors. Also exit early in breakProtrudingToken() (before the expensive call to SourceManager::getSpellingColumnNumber()). This makes formatting huge (100k+-item) braced lists possible. llvm-svn: 189094
* clang-format: Add column layout formatting for braced listsDaniel Jasper2013-08-221-10/+27
| | | | | | | | | | | | | | | | | | | | With this patch, braced lists (with more than 3 elements are formatted in a column layout if possible). E.g.: static const uint16_t CallerSavedRegs64Bit[] = { X86::RAX, X86::RDX, X86::RCX, X86::RSI, X86::RDI, X86::R8, X86::R9, X86::R10, X86::R11, 0 }; Required other changes: - FormatTokens can now have a special role that contains extra data and can do special formattings. A comma separated list is currently the only implementation. - Move penalty calculation entirely into ContinuationIndenter (there was a last piece still in UnwrappedLineFormatter).

Goals: Structure code better and make components easier to use for future features (e.g. column layout for long braced initializers). No functional changes intended. llvm-svn: 188543
