Daniel Jasper 35ca66debf clang-format: Don't format unrelated nested blocks.
With this change:

  SomeFunction(
      [] {
	int i;
	 return i;  // Format this line.
      },
      [] {
	 return 2;  // Don't "fix" this.
      });

Daniel Jasper f83834feb1 clang-format: Simplify and improve stop condition for formatting
unaffected lines with incorrect initial indent.

Starting from:
  namespace {
    int i; // There shouldn't be indentation here.
    int j; // <- call clang-format on this line.
  }

Before:
  namespace {
    int i;
    int j;
    }

After:
  namespace {
    int i;
    int j;
  }

Daniel Jasper f67c32466d clang-format: Be slightly more cautious when formatting subsequent lines after a change. With r251474, clang-format could indent the entire rest of the file, if there is a missing closing brace, e.g. while writing code in an editor.
Summary:
With this change, clang-format stops formatting when either it leaves
the current scope or when it comes back to the initial scope after
going into a nested one.

Daniel Jasper a1036e5d08 clang-format: When a line is formatted, also format subsequence lines if their indent is off.
Summary: This is especially important so that if a change is solely inserting a block around a few statements, clang-format-diff.py will still clean up and add indentation to the inner parts.

Daniel Jasper 75bf203def clang-format: Increase cut-off limit for number of analyzed states.
With more complex structures in C++ Lambdas and JavaScript function
literals, the old value was simply to small. However, this is a
temporary solution, I need to look at this more closely a) to find a
fundamentally better approach and b) to look at whether the more recent
usage of NoLineBreak makes us visit stuff in an unfortunate order
where clang-format waste many states in dead ends.

Daniel Jasper c1bc38ed4f clang-format: Add a new brace style "custom" as well as flags to
control the individual braces. The existing choices for brace wrapping
are now merely presets for the different flags that get expanded upon
calling the reformat function.

All presets have been chose to keep the existing formatting, so there
shouldn't be any difference in formatting behavior.

Also change the dump_format_style.py to properly document the nested
structs that are used to keep these flags discoverable among all the
configuration flags.

Daniel Jasper 20580fd5d3 clang-format: Make SFS_Inline imply SFS_Empty.
In the long run, these two might be independent or we might to only
allow specific combinations. Until we have a corresponding request,
however, it is hard to do the right thing and choose the right
configuration options. Thus, just don't touch the options yet and
just modify the behavior slightly.

Daniel Jasper 1a02822704 clang-format: Fix child-formatting in macros.
This fixes a case where the column limit was incorrectly calculated
leading to a macro like this:

  #define A                                       \
    [] {                                          \
      xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx(        \
          xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx); \
    }

exceeding the column limit.

Manuel Klimek 3d3ea84a4f Refactor clang-format's formatter.
Summary:
a) Pull out a class LevelIndentTracker whose responsibility is to keep track
   of the indent of levels across multiple annotated lines.
b) Put all responsibility for merging lines into the LineJoiner; make the
   LineJoiner iterate over the lines so we never operate on a line that might
   be merged later; this makes the interface safer to use.
c) Move formatting of the end-of-file whitespace into formatFirstToken.

Fix bugs that became obvious after the refactoring:
1. We would not format lines with offsets correctly inside nested blocks if
   only the outer expression was affected:
   int x = s({ // clang-format only this line
     class X {
       public:
    // ^ this starts at the non-modified indnent level; previously we would
    //   not fix this, now we correctly outdent it.
       void f();
     };
   });
2. We would incorrectly align comments across lines that do not have comments
   for lines with nested blocks:
   int expression; // with comment
   int x = s({
     int y; // comment
     int z; // we would incorrectly align this comment with the comment on
            // 'expression'
   });

Pull various parts of the UnwrappedLineFormatter into their own

- the UnwrappedLineFormatter::format function is still too large

Nico Weber 33381f5e0b clang-format: Format Objective-C try blocks like all the other try blocks.
Before:

  @try {
    // ...
  }
  @finally {
    // ...
  }

Now:

  @try {
    // ...
  } @finally {
    // ...
  }

This is consistent with how we format C++ try blocks and SEH try blocks.
clang-format not doing this before was an implementation oversight.

This is dependent on BraceBreakingStyle.  The snippet above is with the
Attach style.  Style Stroustrip for example still results in the "Before:"
snippet, which makes sense since other blocks (try, else) break after '}' too.

2015-02-07 01:57:32 +00:00
Nico Weber fac2371be3 clang-format: Add support for SEH __try / __except / __finally blocks.
This lets clang-format format

    __try {
    } __except(0) {
    }

and

    __try {
    } __finally {
    }

correctly. __try and __finally are keywords if `LangOpts.MicrosoftExt` is set,
so this turns this on.  This also enables a few other keywords, but it
shouldn't overly perturb regular clang-format operation.  __except is a
context-sensitive keyword, so `AdditionalKeywords` needs to be passed around to
a few more places.

Fixes PR22321.
