Clang AST Dumper

A Python-based tool for visualizing and exploring the Abstract Syntax Tree (AST) of C source files using Clang and Tkinter for a graphical user interface (GUI):

• Displays the source code and its corresponding AST side by side.
• Search functionality to quickly locate symbols and their AST representations.
• Fully interactive GUI with expandable and collapsible AST nodes.
• Non-editable code view for clarity.

Python Version

• Python 3.6 or higher

Dependencies

• Clang Python Bindings (libclang)
• Tkinter (comes pre-installed with Python)

Installation

Install Clang bindings:

pip install libclang

Usage

Run the script:

python clang_ast_dumper.py

Explore the Clang AST

1. Load a file:
   • Insert the full path to a given input C file.
   • The source code will be read and parsed into an AST.
2. Search for a Symbol:
   • Type a symbol name in the search bar and press the Search button or hit Enter.
   • The AST and corresponding source code will update to reflect the selected symbol.
   • Leave the search bar empty and press Search to reset to the entire AST of the translation unit.
3. AST Interaction:
   • The AST tree is expandable and collapsible. Click on nodes to view child nodes.
4. View Code:
   • The code view updates automatically when a symbol is selected, displaying its declaration and/or definition.

Examples:

1. Clang AST and source code of an entire translation unit:
2. Clang AST and source code of the main function:
