Bug ID: 48906
Summary: Excessive breaks around return-type-requirement with
BraceWrapping: AfterFunction: true or
AfterControlStatement: MultiLine
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: Formatter
Assignee: unassignedclangb...@nondot.org
Reporter: johel...@gmail.com
CC: djas...@google.com, johel...@gmail.com,
kli...@google.com, llvm-bugs@lists.llvm.org
This was mentioned in [D79773](https://reviews.llvm.org/D79773#2138304).
> Since a compound requirement is neither a control statement nor a function, I
> suppose it might eventually need its own BraceWrapping nested configuration
> flag. For now, I'd prefer if they never break.

Input and expected formatted result:
```C++
template <typename T>
concept EqualityComparable = requires(T a, T b) {
{ a == b } -> bool;
};
```
.clang-format:
```
BraceWrapping:
AfterFunction: true
BreakBeforeBraces: Custom
```
Actual output:
```C++
template <typename T>
concept EqualityComparable = requires(T a, T b)
{
{
a == b
} -> bool;
};
```
.clang-format:
```
BraceWrapping:
AfterControlStatement: MultiLine
BreakBeforeBraces: Custom
```
Actual output:
```C++
template <typename T>
concept EqualityComparable = requires(T a, T b) {
{
a == b
} -> bool;
};
```

Actual output:
```C++
