YAAA Abstract Syntax Tree (AST)

Obtain a structured data representation of YAAA files. Query, process and modify YAAA models programmatically.

The YAAA Abstract Syntax Tree (AST) is a powerful Python module designed to parse and create a structured data representation from YAAA files. Serving as a deserialized form of YAAA models, it allows for an intuitive and accessible manipulation of complex data structures.

Key Features

  • Data Representation: Converts YAAA files into a structured and easily navigable abstract syntax tree, providing a clear and organized view of the model.
  • Traversal and Querying: Equipped with robust helper functions that simplify the process of traversing and querying the AST, enabling users to efficiently locate and extract the necessary information.
  • Modification and Processing: Offers comprehensive tools for modifying and processing the data within the AST, allowing users to seamlessly update and refine their models.

Benefits of YAAA-AST

  • Enhanced Data Manipulation: Easily convert YAAA files into a structured and navigable abstract syntax tree, allowing for intuitive data manipulation and analysis.
  • Efficient Data Retrieval: Utilize robust helper functions to traverse, query, and extract information from the AST quickly and efficiently, saving time and effort.
  • Flexible Model Processing: Seamlessly modify and process YAAA models with comprehensive tools, enabling precise updates and refinements to suit your project needs.
