Bug ID: 26689
Summary: Clang-format Does not Break Before Brace After `Extern
"c"` With Setting `BreakBeforeBraces: Allman`
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Formatter
Assignee: unassignedclangb...@nondot.org
Reporter: sansseco...@gmail.com
CC: djas...@google.com, kli...@google.com,
llvm-bugs@lists.llvm.org
Classification: Unclassified
Clang-Format does not add a break before a opening brace after `extern "C"` if
the setting `BreakBeforeBraces` is set to `Allman`. This is not the expected
behaviour, since official documentation [1] states, that Clang-Format always
breaks before braces if we use this option.
Example: If we save the code
```cpp
extern "C"
{
int foo()
{
return 1;
}
}
```
in a file called `extern.cpp` and format it using `clang-format
-style='{BreakBeforeBraces: Allman}' extern.cpp`, then `clang-format` prints
the following:
```cpp
extern "C" {
int foo() { return 1; }
}
```
However, the expected result is
```cpp
extern "C"
{
int foo() { return 1; }
}
```
or
```cpp
extern "C"
{
int foo() { return 1; }
}
```
