check-requestclang-tidygood first issue
描述
It would be useful to have a clang-tidy check that detects cases where code is clearly trying to rethrow the currently handled exception, but spells it as throw e; instead of throw;.
For example, code like this is easy to write:
try {
f();
} catch (const std::exception &e) {
log(e.what());
throw e;
}
but if the intent is to rethrow the active exception, the clearer spelling is:
try {
f();
} catch (const std::exception &e) {
log(e.what());
throw;
}
The latter expresses the intent directly and avoids the impression that the code is deliberately throwing the caught object as a new exception expression.
