ASTx: Empowering Language Processing Through Custom Abstract Syntax Trees

Language: English

In this talk, we'll introduce ASTx, a versatile Python framework designed for building and manipulating Abstract Syntax Trees (ASTs). ASTs are a fundamental part of compilers and interpreters, making them essential for language processing, code analysis, and transformation. We’ll explore how ASTx can be applied to different programming languages and showcase examples, including a Fibonacci function. Whether you're developing your own language or creating custom code analysis tools, ASTx provides an intuitive and powerful interface to help you work with ASTs efficiently.


The ASTx project, a component of the ArxLang ecosystem, serves as an agnostic Python framework for constructing and representing Abstract Syntax Trees (ASTs). Its primary objective is to provide a versatile and language-independent structure for ASTs, primarily catering to the needs of the ArxLang project but with the flexibility to be utilized across various programming languages and parsing tools.
ASTx supports various data types such as integer, float and boolean, as well as features like control flow elements and operators. When it comes to visualization, ASTx supports Graphviz and console-based visualization. Both are very helpful for graphical interpretation and debugging, but the ascii-based console visualization has added versatility for use during a pdb session, for example.With all these features, ASTx is a intuitive and powerful interface that can be used to create custom code analysis tools or develop your own language.
