Hi everyone,
The latest released `clang-format` (19.1.0) cannot properly format nested calls, when the inner call contains explicit non-type template parameter expressions, containing bitwise operations. Expressions with arithmetic operations are formatted correctly.
`clang-format` 18 produces correct results.
The problem can be reproduced regardless of the presence or contents of `.clang-format`.
Example:
```sh
~ » cat a.cpp
void main() {
// Bitwise operations.
f(g<flag_1 | flag_2>());
f(g<flag_1 & flag_2>());
f(g<flag_1 ^ flag_2>());
f(g<flag_1 & ~flag_2>());
// Arithmetic operations.
f(g<flag_1 + flag_2>());
f(g<flag_1 - flag_2>());
f(g<flag_1 * flag_2>());
f(g<flag_1 / flag_2>());
}
~ » clang-format a.cpp
void main() {
// Bitwise operations.
f(g < flag_1 | flag_2 > ());
f(g < flag_1 & flag_2 > ());
f(g < flag_1 ^ flag_2 > ());
f(g < flag_1 & ~flag_2 > ());
// Arithmetic operations.
f(g<flag_1 + flag_2>());
f(g<flag_1 - flag_2>());
f(g<flag_1 * flag_2>());
f(g<flag_1 / flag_2>());
}
```
