libtooling

问题 I am working on clang libtooling. So far I am managed to get the macro where it is getting referred in the source file through visitDeclRefExpr(DeclRefExpr *DR) But can I get a list of macros with its name and its expansion as string. exampleprogram.c #define abc ab #define sum 0 int main() { int ab; abc = abc + 0; return 0; } can I get the output like the following abc -- ab sum -- 0 How can I achieve this output with clang libtooling. How can I implement with the clang libtooling? Please

问题 TL;DR; How to get the macro name used for size of a constant size array declaration, from a callExpr -> arg_0 -> DeclRefExpr. Detailed Problem statement: Recently I started working on a challenge which requires source to source transformation tool for modifying specific function calls with an additional argument. Reasearching about the ways i can acheive introduced me to this amazing toolset Clang. I've been learning how to use different tools provided in libtooling to acheive my goal. But

问题 I'm writing a libtooling refactoring tool. I have a class, let's say Foo , defined in a header called foo.h . I want to see if foo.h is included in a file. Currently, to check if bar.cc includes foo.h , I'm just matching using recordDecl(hasName("Foo")) . This works because class Foo { ... }; will exist inside of bar.cc 's AST after preprocessing, if bar.cc includes foo.h . But this doesn't work if, for example, bar.cc includes cat.h which includes foo.h . I want bar.cc to EXPLICITLY include

问题 Is there any way to get clang::SourceLocation for every #include in file by its clang::FileID or clang::FileEntry or something? 回答1: What about using source manager's GetIncludedLoc function which takes fileid as parameter. SourceManager.GetIncludedLoc(fileid) 回答2: Thank's @Hemant for your answer, you're right I Already found that by myself (in clang 3.8 it is called getIncludeLoc ) but forgot to write here. I used this to find the location after all #includes where i can put my own. Here's

问题 I'm working on my reflection tool with clang 8.0.1. And right now I need to print Expr with all names fully qualified. I already tried builtin prettyPrint function with FullyQualifiedName bit set to true. But it still gives incorrect result. For this piece of code: namespace math { struct Transform { float val; [[custom_attr(&Transform::public_val)]] void foo(); }; } It gives me &Transform::public_val instead of &math::Transform::public_val And for static_cast<float (*)(const Transform&)>

问题 tldr;> How do I hide warnings from system headers in clang-tidy? I have the following minimal example source file, which triggers a clang-tidy warning in the system headers: #include <future> int main() { std::promise<int> p; p.set_value(3); } Calling it with libstdc++ 7.0.1 using clang-tidy 4.0.0 on Ubuntu 17.04: $ clang-tidy main.cpp -extra-arg=-std=c++14 yields Running without flags. 1 warning generated. /usr/lib/gcc/x86_64-linux-gnu/7.0.1/../../../../include/c++/7.0.1/mutex:693:5: warning
