This PR addresses instances of compiler warning C4146 that can be
replaced with std::numeric_limits. Specifically, these are cases where a
literal such as '-1ULL' was used to assign a value to a uint64_t
variable. The intent is much cleaner if we use the appropriate
std::numeric_limits value<Type>::max() for these cases.
Addresses #147439
This allows simplification of code that checks if a token is an
Objective-C keyword.
Also, delete the following in
UnwrappedLineParser::parseStructuralElement():
- an else-after-break in the tok::at case
- the copypasted code in the tok::objc_autoreleasepool case
The use of Cpp11BracedListStyle with BinPackArguments=False avoids bin
packing until reaching a hard-coded limit of 20 items. This is an
arbitrary choice. Introduce a new style option to allow disabling this
limit.
In clang-format, multiline templates have the `>` on the same line as
the last parameter:
```c++
template <
typename Foo,
typename Bar>
void foo() {
```
I would like to add an option to put the `>` on the next line, like
this:
```c++
template <
typename Foo,
typename Bar
>
void foo() {
```
An example of a large project that uses this style is NVIDIA's CUTLASS,
here is an example:
https://github.com/NVIDIA/cutlass/blob/main/include/cutlass/epilogue/dispatch_policy.hpp#L149-L156
My reasoning is that it reminds me of this style of braces:
```c++
if (foo()) {
bar();
baz();}
```
Most people agree this is better:
```c++
if (foo()) {
bar();
baz();
}
```

The penalty for breaking before a member access is hard-coded to 150.
Add a configuration option to allow setting it.

`export { ... }` blocks can get a bit long, so I thought it would make
sense to have an option that makes it so their contents are not indented
(basically the same argument as for namespaces).
This is based on the `NamespaceIndentation` option, except that there is
no option to control the behaviour of `export` blocks when nested because
nesting them doesn’t really make sense.
Additionally, brace wrapping of short `export { ... }` blocks is now controlled by the
`AllowShortBlocksOnASingleLine` option. There is no separate option just for `export`
blocks because you can just write e.g. `export int x;` instead of `export { int x; }`.
This closes#121723.
It wraps the body of namespace with additional newlines, turning this code:
```
namespace N {
int function();
}
```
into the following:
```
namespace N {
int function();
}
```

This fixes#101363 which is a resurrection of a previously opened but
never completed review: https://reviews.llvm.org/D11851
The feature is to allow code like the following not to be broken across
multiple lines:
```
namespace foo { class bar; }
namespace foo { namespace bar { class baz; } }
```
Code like this is commonly used for forward declarations, which are
ideally kept compact. This is also apparently the format that
include-what-you-use will insert for forward declarations.
Also, fix an off-by-one error in `CompactNamespaces` code. For nested
namespaces with 3 or more namespaces, it was incorrectly compacting
lines which were 1 or two spaces over the `ColumnLimit`, leading to
incorrect formatting results.
* Convert `ReflowComments` from boolean into a new `enum` which can take
on the value `RCS_Never`, `RCS_IndentOnly`, or `RCS_Always`. The first
one is equivalent to the old `false`, the third one is `true`, and the
middle one means that multiline comments should only have their
indentation corrected, which is what Doxygen users will want.
* Preserve backward compatibility while parsing `ReflowComments`.
- Add a `CHECK_PARSE` for `AcrossComments`.
- Add a `CHECK_PARSE_NESTED_BOOL` for `AlignFunctionPointers`.
- Remove redundant statements.
- Clean up documentation.
Enabling AlignConsecutiveDeclarations also aligns function prototypes
or declarations. This is often unexpected as typically function
prototypes, especially in public headers, don't use any padding.
Setting AlignFunctionDeclarations to false will skip this alignment.
It is by default set to true to keep compatibility with prior
versions to not make unexpected changes.
Fixes#74320
Address #101550 by adding OwnLineWithBrace option for RequiresClausePosition. This permits placing a following '{' on the same line as the requires clause.
Thus, instead of:
```
bool Foo ()
requires(true)
{
return true;
}
```
we have:
```
bool Foo ()
requires(true) {
return true;
}
```
If the function body is empty, we'll get:
```
bool Foo ()
requires(true) {}
```
I attempted to get a line break between the open and close braces, but
failed. Perhaps that's fine -- it's rare and only happens in the empty
body case.
By default, clang-format packs binary operations, but it may be
desirable to have compound operations be on individual lines instead of
being packed.
This PR adds the option `BreakBinaryOperations` to break up large
compound binary operations to be on one line each.
This applies to all logical and arithmetic/bitwise binary operations
Maybe partially addresses #79487 ?
Closes#58014Closes#57280
The __attribute((specifier-list)) currently is formatted based on the
SpacesInParensOptions.Other (previously, SpacesInParentheses). This
change allows finer control over addition of spaces between the
consecutive parens, and between the inner parens and the list of
attribute specifiers.
