<pre>Ubuntu clang version 3.8.0-svn257311-1~exp1 (trunk) (based on LLVM 3.8.0)
For a *.cpp file with the contents
1 void f()
2 {
3 Foo::
4 }
...and a completion right after the second colon (line 3, column 10), libclang
will suggest CXCompletionContext_DotMemberAccess. Foo is unknown, but still
this shouldn't suggest CXCompletionContext_DotMemberAccess?
Tested with the following code:
#include <clang-c/Index.h>
#undef NDEBUG
#include <cassert>
#include <cstdlib>
#include <cstdio>
int main(int argc, char *argv[])
{
if (argc != 4) {
fprintf(stderr, "Usage: $0 <file> <line> <column>\n");
return 0;
}
const char *filePath = argv[1];
const unsigned line = unsigned(atoi(argv[2]));
const unsigned column = unsigned(atoi(argv[3]));
// Parse
CXIndex index = clang_createIndex(0, /*displayDiagnostics*/ 1); // ...to
compare
CXTranslationUnit tu = clang_parseTranslationUnit(index, argv[1], 0, 0,
NULL, 0, 0);
// Complete
CXCodeCompleteResults *completeResults = clang_codeCompleteAt(tu,
filePath, line, column, NULL, 0, 0);
// Test
const unsigned long long contexts =
clang_codeCompleteGetContexts(completeResults);
const bool wasDotMemberCompletion = contexts &
CXCompletionContext_DotMemberAccess;
assert(!wasDotMemberCompletion);
return 0;
