This required rudimentary changes to static initializer lists, but we
are not yet formatting them in a reasonable way. That will be done in a
subsequent patch.

This addresses llvm.org/PR14815.
To implement this I introduced a line type during parsing and moved the
definition of TokenType out of the struct for increased readability.
Should have done the latter in a separate patch, but it would be hard to
pull apart now.
llvm-svn: 171724
The case that we wanted to write a test for cannot happen, as the
UnwrappedLineParser already protects against it. Added an assert to
prevent regressions of that assumption.
llvm-svn: 171720
We would format:
#define A \
int f(a); int i;
as
#define A \
int f(a);\
int i
The fix will break up macro definitions that could fit a line, but hit
the last column; fixing that is more involved, though, as it requires
looking at the following line.
llvm-svn: 171715
Previously, we'd format
int i;\
// comment
as
int i; // comment
The problem is that the escaped newline is part of the next token, and
thus the raw token text of the comment doesn't start with "//".
llvm-svn: 171713
If a token follows directly on an escaped newline, the escaped newline
is stored with the token. Since we re-layout escaped newlines, we need
to treat them just like normal whitespace - thus, we need to increase
the whitespace-length of the token, while decreasing the token length
(otherwise the token length contains the length of the escaped newline
and we double-count it while indenting).
llvm-svn: 171706
If we find an unexpected closing brace, we must not stop parsing, as
we'd otherwise not layout anything beyond that point.
If we find a structural error on the highest level we'll not re-indent
anyway, but we'll still want to format within unwrapped lines.
Needed to introduce a differentiation between an expected and unexpected
closing brace.
llvm-svn: 171666
To parse # correctly, we need to know whether it is the first token in a
line - we can deduct this either from the whitespace or seeing that the
token is the first in the file - we already calculate this information.
This patch moves the identification of the first token into the
getNextToken method and stores it inside the FormatToken, so the
UnwrappedLineParser can stay independent of the SourceManager.
llvm-svn: 171640
Some of this is still pretty rough (note the load of FIXMEs), but it is
strictly an improvement and fixes various bugs that were related to
macro processing but are also imporant in non-macro use cases.
Specific fixes:
- correctly puts espaced newlines at the end of the line
- fixes counting of white space before a token when escaped newlines are
present
- fixes parsing of "trailing" tokens when eof() is hit
- puts macro parsing orthogonal to parsing other structure
- general support for parsing of macro definitions
Due to the fix to format trailing tokens, this change also includes a
bunch of fixes to the c-index tests.
llvm-svn: 171556
Fixes:
- incorrect handling of multiple consecutive preprocessor directives
- crash when trying to right align the escpaed newline for a line that
is longer than the column limit
- using only ColumnLimit-1 columns when layouting with escaped newlines
inside preprocessor directives
llvm-svn: 171401
This fixes llvm.org/PR14786.
We will need to split there as a last resort, but that should be done
consistently independent of whether the type is a template type or not.
Before:
template <typename T>
aaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaa<T>
::aaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
After:
template <typename T>
aaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaa,
aaaaaaaaaaaaaaaaaaaaaaaaaa<T>::aaaaaaaaaa,
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa);
llvm-svn: 171400
This fixes llvm.org/PR14687.
Also fixes segfault for lines starting with * or &.
Before:
a *~b;
*a = 1; // <- this segfaulted
After:
a * ~b;
*a = 1; // no segfault :-)
llvm-svn: 171396
This is the first step towards handling preprocessor directives. This
patch only fixes the most pressing issue, namely correctly escaping
newlines for tokens within a sequence of a preprocessor directive.
The next step will be to fix incorrect format decisions on #define
directives.
llvm-svn: 171393
This prevents formattings like this (assuming "parameter" doesn't fit the line):
bool f = someFunction() && someFunctionWithParam(
parameter) && someOtherFunction();
Here, "parameter" - the start of line 2 - has a parenthesis level of 2, but
there are subsequent tokens ("&&" and "someOtherFunction") with a lower level.
This is bad for readability as "parameter" hides "someOtherFunction". With this
patch, this changes to:
bool f = someFunction() &&
someFunctionWithParam(parameter) &&
someOtherFunction();
llvm-svn: 171038
This changes:
int Result = a + // force break
b;

This fixes llvm.org/pr14686.
We used to add too many spaces for different versions of overloaded operator
function declarations/definitions. This patch changes, e.g.
operator *() {}
operator >() {}
operator () () {}
to
operator*() {}
operator>() {}
operator()() {}
llvm-svn: 171028
With this patch, splitting after binary operators has a panelty corresponding
to the operator's precedence. We used to ignore this and eagerly format like:
if (aaaaaaaaaaaaaaaaaaaaaaaaa || bbbbbbbbbbbbbbbbbbbbbbbbb &&
ccccccccccccccccccccccccc) { .. }
With this patch, this becomes:
if (aaaaaaaaaaaaaaaaaaaaaaaaa ||
bbbbbbbbbbbbbbbbbbbbbbbbb && ccccccccccccccccccccccccc) { .. }
llvm-svn: 171007
We used to not really format them. Now we do:
for (MachineBasicBlock::succ_iterator SI = BB->succ_begin(),
SE = BB->succ_end();
SI != SE; ++SI) {
This is just one example and I am sure we still mess some of them up, but it
is a step forward.

use clang's formatter. Currently, formatter is used
to format declaration tags for xml comments. Since formatter
is in flux and its change will break several of the clang comment
tests, only a single tests is formatted using this facility.
Doug has reviewed and approved it for check-in.
llvm-svn: 170467
We used to format initializers like this (with a sort of hacky implementation):
Constructor()
: Val1(A),
Val2(B) {
and now format like this (with a somewhat better solution):
Constructor()
: Val1(A), Val2(B) {
assuming this would not fit on a single line. Also added tests.
As a side effect we now first analyze whether an UnwrappedLine needs to be
split at all. If not, not splitting it is the best solution by definition. As
this should be a very common case in normal code, not exploring the entire
solution space can provide significant speedup.
llvm-svn: 170457
This allows for writing tests including line comments easier and more readable.
We will need more of those tests in the future and also line comments are
useful to force line breaks in tests.

avoided.
This required a minor modification of the memoization as now the
"CurrentPenalty" depends on whether or not we break before the current
token. Therefore, the CurrentPenalty should not be memoized but added
after retrieving a value from memory. This should not affect the runtime
behavior.

The problem is that a partial match of an (explicit or implicit) allOf matcher
binds results, i.e.
recordDecl(decl().bind("x"), hasName("A"))
can very well bind a record that is not named "A". With this fix, the common
cases of stumbling over this bug are fixed by the BoundNodesMap overwriting the
results of a partial match. An error can still be created with a weird
combination of anyOf and allOf (see inactive test). We need to decide whether
this is worth fixing, as the fix will have performance impact.

When recursively visiting the generated matches, the aggregated bindings need
to be copied during the recursion. Otherwise, we they might not be properly
overwritten (which is shown by the test), or there might be bound nodes present
that were bound on a different matching branch.

Often users of the ASTMatchers want to add tasks that are done once per
translation unit, for example, cleaning up caches. Combined with the
interception point for the end of source file one can add to the factory
