C/C++ tooling for testing and visualisation
To use this package, run the following command in your project's root directory:
deXtool is a framework for writing plugins using libclang. The main focus is tools for testing and analyze.
The plugins in a standard installation of deXtool are:
- Analyze. Analyze C/C++ code to generate complexity numbers such as McCabe.
- C TestDouble. Analyze C code to generate a test double implementation.
- C++ TestDouble. Analyze C++ code to generate a test double implementation.
- Compilation Database. Tool for manipulating db(s) such as merge, compiler flag filtering, relative->absolute path. Usually called compile_commands.json.
- Mutate. Mutation testing tool for C/C++.
- GraphML. Analyze C/C++ code to generate a GraphML representation. Call chains, type usage, classes as groups of methods and members.
- Intercept. Analyze a C header together with a config to generate interceptor functions.
- UML. Analyze C/C++ code to generate PlantUML diagrams.
- Analyze: production ready.
- C TestDouble: production ready. The API of the generated code and how it behaves is stable.
- C++ TestDouble is production ready. The API of the generated code and how it behaves is stable.
- CompileDB: alpha.
- Fuzzer: alpha.
- GraphML: beta.
- Intercept: alpha.
- UML: beta.
- Mutate: production ready.
deXtool depends on the following software packages:
- llvm (4.0+, both libclang and LLVM is needed)
- cmake (3.5+)
- D compiler (dmd 2.076.1+, ldc 1.8.0+)
- sqlite3 (3.19.3-3+)
deXtool has been tested with libclang [4.0, 5.0].
For people running Ubuntu two of the dependencies can be installed via apt-get. The version of clang and llvm depend on your ubuntu version.
sudo apt install cmake llvm-4.0 llvm-4.0-dev clang-4.0 libclang-4.0-dev libsqlite3-dev ldc dub
Once the dependencies are installed it is time to download the source code and build the binaries.
git clone https://github.com/joakim-brannstrom/dextool.git cd dextool mkdir build cd build cmake -DCMAKE_INSTALL_PREFIX=/path/to/where/to/install/dextool/binaries .. make install -j2
Done! Have fun. Don't be shy to report any issue that you find.
Common Build Errors
Mismatch Clang and LLVM
To build dextool the dev packages are required. Dextool is optimistic and assume that the latest and greatest version of llvm+libclang should be used. But this also requires that the dev packages are installed.
If you get this error:
libclang_interop.hpp:13:10: fatal error: clang/Analysis/CFG.h: No such file or directory #include <clang/Analysis/CFG.h>
It means that you need to install
libclang-x.y-dev for the version that deXtool detected.
See the usage examples in respective plugin directory:
Jacob Carlborg for his excellent DStep. It was used as a huge inspiration for this code base. Without DStep deXTool wouldn't exist.
