I want to write a matcher, which excludes classes containing incomplete types like: std::unique_ptr<ForwardDeclared>, but it is not identified as one, because it is a template type (I think so). Does anyone know how to circumvent this? Minimal code: // … class MoveDefaultToDecl: public MatchFinder::MatchCallback { // … public: void run(const MatchFinder::MatchResult& r) override { ..

I am a newcomer who is beginning to learn the principles of compilation. I am trying to implement a simple C-like scripting language interpreter using C++17. I have completed lexical analysis and parser, and can convert code text into AST representation.The next step is to execute the code by traversing the AST. I understand the ..
Consider the following struct definition in foo.cc: struct Foo { int &bar; }; Because bar has reference type, the implicit trivial default constructor Foo::Foo() is implicitly deleted. However, this fact does not seem to be reflected in the AST generated by clang. E.g. running clang -Xclang -ast-dump foo.cc results in: `-CXXRecordDecl 0x5612ba4c03b8 <test.cc:1:1, col:24> col:8 ..
I have a big project, and a slew of C++ class member functions of the form: Return CClass::MemberFunction( Arg1 arg1, //… std::weak_ptr<IMemberFunctionListenerInterface> listener) { //… } I’m trying to write a matcher that finds functions like these, which have arguments whose types have the string "Listener" in their name. I can find functions with arguments ..
I want to analyze a specific file located here (https://github.com/larmillo/GIZMO-CMZ/blob/master/gravity/forcetree.c) I am trying to parse it using Clang as a frontend that can generate an AST for me. Specifically the operation I am interested in doing is something like this: clang -Xclang -ast-dump ./gravity/forcetree.c -I /usr/include/hdf5/serial -I /usr/include/mpi -I /home/esmerald/Documents/uci/Research/C2Bluespec/GIZMO-CMZ-master/grackle/src/clib This produces the error: /usr/bin/ld: ..
I have a function like this to get the the AST from a file. antlr4::tree::ParseTree *get_ast(std::string &filename) { std::ifstream stream; stream.open(filename); antlr4::ANTLRInputStream input(stream); Lexer lexer(&input); antlr4::CommonTokenStream tokens(&lexer); Parser parser(&tokens); antlr4::tree::ParseTree *tree = parser.program(); return tree; } But when using the return value, it seems that what tree is pointing to is already cleared (on the ..
Im working with the creation of the abstract syntax tree for a specific domain language. So the snippet here just allocating a memory for the children of the node. However, I can’t grasp what should I do in here, everytime the push_back happens, the previous content will be modified and be the same with the ..
i have the same problem as Get operator type for CXCursor_BinaryOperator. with the solution in this post as mentioned: only works for trivial expressions. For 2 + 2 * 2 this will confuse * by finding + first, since the extent covers the whole expression, including subexpressions, and not just the operator so i changed ..
I want to build a C++ refactoring service that isnt just one-shot (i.e. run once and terminate), but can be queried to do refactorings (via network or stdin) and re-use already created ASTs from previous queries again. I cannot find any example how to do this and the prime usage of ClangTool seems to be ..
do somebody know how i can get a AST Tree from PHP Code with C++ in Windows? i found this in php: https://github.com/nikic/php-ast and for example this: https://github.com/nikic/PHP-Parser in php there is a very easy way to do it – but what is with c/c++? i tried it with astkit and some others like hhvm ..
