I very much like this check. I only have a few minor comments, but maybe this
encourages others to have a look too!
================
Comment at: clang-tidy/hicpp/MultiwayPathsCoveredCheck.cpp:85
+ diag(ElseIfWithoutElse->getLocStart(),
+ "potential uncovered codepath found; add an ending else branch");
+ return;
----------------
I'm not a big fan of the 'found', can we just omit it? The same goes for the
other diags.
================
Comment at: clang-tidy/hicpp/MultiwayPathsCoveredCheck.cpp:96
+ // Only the default branch (we explicitly matched for default!) exists.
+ if (CaseCount == 1) {
+ diag(SwitchWithDefault->getLocStart(),
----------------
Why not a switch?
================
Comment at: clang-tidy/hicpp/MultiwayPathsCoveredCheck.cpp:152
+ // Should be written as an IfStmt.
+ if (CaseCount == 1) {
+ diag(SwitchWithoutDefault->getLocStart(), "switch stmt with only one "
----------------
I'm aware that the message and fixme are different, but since the structure is
so similar to the handling of the other switch case, I wonder if there is any
chance we could extract the common parts?
