2009-09-22Tweak the code-completion results ranking and formation, so thatDouglas Gregor
members found in base classes have the same ranking as members found in derived classes. However, we will introduce an informative note for members found in base classes, showing (as a nested-name-specifier) the qualification to name the base class, to make it clear which members are from bases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82586 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-22Implement code completion within a function call, triggered after theDouglas Gregor
opening parentheses and after each comma. We gather the set of visible overloaded functions, perform "partial" overloading based on the set of arguments that we have thus far, and return the still-viable results sorted by the likelihood that they will be the best candidate. Most of the changes in this patch are a refactoring of the overloading routines for a function call, since we needed to separate out the notion of building an overload set (common to code-completion and normal semantic analysis) and then what to do with that overload set. As part of this change, I've pushed explicit template arguments into a few more subroutines. There is still much more work to do in this area. Function templates won't be handled well (unless we happen to deduce all of the template arguments before we hit the completion point), nor will overloaded function-call operators or calls to member functions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82549 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-21Change all the Type::getAsFoo() methods to specializations of Type::getAs().John McCall
Several of the existing methods were identical to their respective specializations, and so have been removed entirely. Several more 'leaf' optimizations were introduced. The getAsFoo() methods which imposed extra conditions, like getAsObjCInterfacePointerType(), have been left in place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82501 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-21When providing a code-completion suggestion for a hidden name, includeDouglas Gregor
a nested-name-specifier that describes how to refer to that name. For example, given: struct Base { int member; }; struct Derived : Base { int member; }; the code-completion result for a member access into "Derived" will provide both "member" to refer to Derived::member (no qualification needed) and "Base::member" to refer to Base::member (qualification included). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82476 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-21Enhance "case" code completion in C++ to suggest qualified names forDouglas Gregor
enumerators when either the user intentionally wrote a qualified name (in which case we just use that nested-name-specifier to match the user's code) or when this is the first "case" statement and we need a qualified name to refer to an enumerator in a different scope. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82474 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-18In C++ code completion, only suggest the "template" keyword after ".",Douglas Gregor
"->", or "::" if we will be looking into a dependent context. It's not wrong to use the "template" keyword, but it's to needed, either. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82307 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-18Make the construction of the code-completion string for a functionDouglas Gregor
template smarter, by taking into account which function template parameters are deducible from the call arguments. For example, template<typename RandomAccessIterator> void sort(RandomAccessIterator first, RandomAccessIterator last); will have a code-completion string like sort({RandomAccessIterator first}, {RandomAccessIterator last}) since the template argument for its template parameter is deducible. On the other hand, template<class X, class Y> X* dyn_cast(Y *Val); will have a code-completion string like dyn_cast<{class X}>({Y *Val}) since the template type parameter X is not deducible from the function call. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82306 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-18For code completion in C++ member access expressions and tag names,Douglas Gregor
look into the current scope for anything that could start a nested-names-specifier. These results are ranked worse than any of the results actually found in the lexical scope. Perform a little more pruning of the result set, eliminating constructors, __va_list_tag, and any duplication of declarations in the result set. For the latter, implemented NamespaceDecl::getCanonicalDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82231 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-18Implement code completion for tags, e.g., code completion after "enum"Douglas Gregor
will provide the names of various enumerations currently visible. Introduced filtering of code-completion results when we build the result set, so that we can identify just the kinds of declarations we want. This implementation is incomplete for C++, since we don't consider that the token after the tag keyword could start a nested-name-specifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82222 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-17Initial implementation of a code-completion interface in Clang. InDouglas Gregor
essence, code completion is triggered by a magic "code completion" token produced by the lexer [*], which the parser recognizes at certain points in the grammar. The parser then calls into the Action object with the appropriate CodeCompletionXXX action. Sema implements the CodeCompletionXXX callbacks by performing minimal translation, then forwarding them to a CodeCompletionConsumer subclass, which uses the results of semantic analysis to provide code-completion results. At present, only a single, "printing" code completion consumer is available, for regression testing and debugging. However, the design is meant to permit other code-completion consumers. This initial commit contains two code-completion actions: one for member access, e.g., "x." or "p->", and one for nested-name-specifiers, e.g., "std::". More code-completion actions will follow, along with improved gathering of code-completion results for the various contexts. [*] In the current -code-completion-dump testing/debugging mode, the file is truncated at the completion point and EOF is translated into "code completion". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82166 91177308-0d34-0410-b5e6-96231b3b80d8
