Bug ID: 25708
Summary: Configure the alignment/formatting of macros
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Formatter
Assignee: [email protected]
Reporter: [email protected]

Classification: Unclassified
AFAIK there are no current ways of configure the alginment/formatting of
macros.
I would like to be able to configure the alignment of macros.
For example, consider the current situation:
void foo() {
#ifdef BAR
do_something();
#endif
#pragma omp target data map ...
{
#pragma omp target ...
#pragma omp teams ...
#pragma omp distribute
for (int i = 0; i < size; i += num_blocks) {
#pragma omp parallel for
for (int j = i; j < i + num_blocks; ++j) {
y[i] = a * x[i] + y[i];
}
}
}
}
This looks horrible _to me_. I would very much prefer:
- macros to be indented as normal code,
- for #ifdef ... endif blocks to span its own "scope of indentation"
resulting in:
void foo() {
#ifdef BAR
do_something(); // see indentation here
#endif
#pragma omp target data map ...
{
#pragma omp target ...
#pragma omp teams ...
#pragma omp distribute
for (int i = 0; i < size; i += num_blocks) {
#pragma omp parallel for
for (int j = i; j < i + num_blocks; ++j) {
y[i] = a * x[i] + y[i];
}
}
}
}
which looks much better _to me_. It would be nice if there was an option (or
multiple) to switch between both styles (and maybe others like leaving the # at
the beginning of the line but indenting the body of the macro). In particular
since I work on some code bases that follow this style and which clang-format
currently "destroys".
