Bug ID: 43947
Summary: mis-indentation caused by macro/template instantiation
Product: clang
Version: 9.0
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Formatter
Assignee: unassignedclangb...@nondot.org
Reporter: s...@lukas-wirz.de
CC: djas...@google.com, kli...@google.com,
llvm-bugs@lists.llvm.org
The problem I'm observing is not limited to clang-format-9 but also exists in 7
and 8 (I'm using the versions that are packaged in Debian/testing).
The .clang-format I'm using contains only "BasedOnStyle: LLVM".
The file that gets misformatted is
<<<<<<<
#define container_output(container)
\
template <typename T>
\
ostream &operator<<(ostream &s, const container<T> &v) {
\
s << "{";
\
for (typename container<T>::const_iterator x(v.begin()); x != v.end();) {
\
s << *x;
\
if (++x != v.end())
\
s << ",";
\
}
\
s << "}";
\
return s;
\
}
container_output(vector)
int myfunc() {
return 0;
}
>>>>>>>
where the macro definition is irrelevant and can be outcommented.
Instantiating the template defined in the macro (correct without semicolon)
causes the following function to be indented as:
<<<<<<<
container_output(vector)
int myfunc() {
return 0;
}
>>>>>>>
which is clearly two indentation-levels too many in the first line.
cheers, Lukas Wirz
