Given the following test.cpp- #include <vector> using namespace std; class MyData {}; class MoreData {}; class MyClass { public: void Method2(vector<int> vec){} void Method3(const vector<int>& vec){} void Method4(vector<MoreData> vec){} void Method5(const vector<MoreData>& vec){} void Method7(vector<MyData> vec){} // Match works for this void Method8(const vector<MyData>& vec){} // How to match by reference? }; I can create ..

I need to convert an abstract syntax tree (AST) to C++ Source Code. For Java Code, there’s the Spoon Library (https://github.com/INRIA/spoon) that does that. Does anybody know if there’s a similar tool for C++? Source: Windows Que..
I have a mathematical expression such as: expression = function123(v1, v2) and I want to transform it to: expression = (function1(v1, v2) + function2(v1, v2) + function3(v1, v2)) In order to solve this problem, I tried to utilize regular expressions, such as: "function123(([^)]+),([^)]+))" and replace using the interior tokens to get what I want. Regular ..

I would like to generate an AST from a set of C/C++ code in which I know that there will be missing imports. Here is a sample. int main() { printf("Hello, World!"); } I’ve tried doing this with clang -Xclang -ast-dump -fsyntax-only test.cpp. But it stops exporting the AST when it encounters printf. With Import ..
I’m following a youtube video on "How to make a programming language?" he is writting all the code in python, but I choose C++. Youtube video link. I easily followed the first video, but got stuck on 2nd one, while creating parser, I’m using g++ version 8.1.0 on Windows 11. Output: pl > 123+13 ( ..
I am trying to analyze clang’s AST coming from this small code snippet. struct Foo { Foo() = default; Foo(int num) : i(num) {} Foo(Foo &&other) { i = other.i; other.i = 0; } int i = 0; }; Foo createAElidable(int i); void func() { Foo foo = createAElidable(1234); } Foo createAElidable(int i) { return ..
In Short I need to get some kind of AST representation of GCC and Clang. Due to their complexity and size, I cannot find an easy way to achieve this. The Details For a project with the goal of comparing large programs with respect to their AST (similarly to how DECKARD does it), I require ..
I am trying to extract the possible true/false combinations from an IfStmt condition to have a separate list of expressions which correspond to testing "Multiple Condition Coverage". Example: whenever my clang pass encounters an IfStmt such as if (x == 1 && (y+z > 0) || k) then my output should be a list of ..
I need to generate clang ASTs of different C++ files in order to extract method invocation and class instance creation nodes, declaration nodes and control-flow nodes. I can already generate and print the AST of a given file file.cpp using the command clang -Xclang -ast-dump -fsyntax-only file.cpp , but as I am new to clang, ..
