astor enables developers to easily manipulate Python source code by leveraging the Abstract Syntax Tree (AST) representation. The project focuses on providing tools for reading, writing, and transforming Python code through its AST. It addresses challenges associated with code analysis, manipulation, and regeneration, especially in scenarios involving code refactoring or automated code generation. astor uses Python's built-in ast module to provide a flexible and accessible way to work with the AST.
astor excels in enabling round-tripping of ASTs back to Python code, even when the AST lacks standard attributes. It provides a convenient way to pretty-print ASTs for deeper code understanding. The library offers non-recursive tree traversal, allowing for fine-grained control over node visitation and manipulation, making it suitable for complex code transformations.
- Round-trip AST: Converts modified ASTs back to Python code with options for code formatting and preservation of original structure.
- AST Pretty-printing: Generates readable, formatted representations of the AST for detailed analysis.
- Non-recursive Traversal: Offers flexible traversal options, allowing customization of node visitation behavior.
- Tree Access: Provides easy access to parent nodes and allows for function execution during tree traversal.
- Code Transformation: Enables programmatic modification of Python code by manipulating the AST directly.
- Integration with Tools: Facilitates the development of tools for code analysis, refactoring, and generation.
- Extensible: Provides hooks for extending the traversal process and implementing custom node handling.
