Bug ID: 26641
Summary: Spell checking makes diagnostic worse when forgetting
template parameters on a template
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org
Reporter: nicolaswe...@gmx.de
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
This is is a good experience:
$ cat test.cc
#include <vector>
void f() {
std::vector v;
}
$ clang -c test.cc
test.cc:4:8: error: use of class template 'std::vector' requires template
arguments
std::vector v;
^
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/vector:477:29:
note: template is declared here
class _LIBCPP_TYPE_VIS_ONLY vector
^
1 error generated.
This isn't:
$ cat test.cc
#include <ratio>
#include <vector>
void f() {
std::vector v;
}
$ clang -c test.cc
test.cc:5:8: error: no type named 'vector' in namespace 'std'; did you mean
'hecto'?
std::vector v;
~~~~~^~~~~~
hecto
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/ratio:265:43:
note: 'hecto' declared here
typedef ratio< 100LL, 1LL> hecto;
^
1 error generated.
We probably should prefer the original diagnostic if there's a template with an
edit distance of 0 that's just missing the type parameters.
