This project aims to make a quick visual representation for a C++ project (though Python support is planned).
Possible use-cases:
- Showing visual representation of different code structures for teaching
- Code dependency analysis
- Per-function code structure analysis.
- (PLANNED) Performance analyzing
- (PLANNED) Unit-test and security analysis
sudo apt install llvm
sudo apt install libclang-11-dev
git clone git@github.com:codereptile/visualizer.git
pip3 install -r requirements.txt
python3 visualizer.py cpp --target examples/segment_tree --scale 0.5
You can also use -b or --bruteforce to avoid errors.
UP, DOWN, LEFT, RIGHT - move respectively
0 - increase size (zoom in)
9 - decrease size (zoom out)
Loops are Red,
Code lines are Blue,
Sugar is Sweet,
And so are you.
Btw, Functions are Grey, Ifs are green with a black line separating main statement and else. All other black lines are function calls.
What are you using for parsing C++?
— Clang
Why not use <insert your favorite C++ parser>?
—Because parsing C++ propely requires almost compiling it,
so only by using a compiler can we get a 100% correct output.
Easiest example is operator << which in most parsers is registered as a binary expression, when in reality it is a function call.
- Function calls inside Loop and If conditions are not registered
- No way to see actual code from visualizer
- Function arguments not registered
- Python support is yet to come
- No way to see how many times a function is called from a single line
- No support for outside-of-function code
- No way to resize/move in editor
- It's hard to tell code structure if there are many If statements
- Class / struct constructors are not registered as function calls
- If an included library is not found, some code may be absent!!! (this can be partually avoided by commenting the problematic include)
- No way to add libraries that shouldn't be rendered
- No switch case support
- Operator calls are not detected, even if they are user-defined
- On large projects moving/resizing is quite CPU-intensive and takes significant time (projects of around 1500 lines of code are rendered at around 7-8 FPS (125-150ms response time))
