Can I use it for Julia AST meta-programming?

Yes, it includes specific navigators for S-expressions and typed AST nodes (Atom, SList), making it highly effective for symbolic manipulation and code rewriting.

What is Specter-style navigation?

It is a paradigm where a single path expression acts as a 'lens', allowing you to both find (select) and modify (transform) data within complex nested structures without writing separate logic.

Is it performant for large Julia datasets?

Yes, it implements inline caching and continuation-passing style (CPS) to ensure that path composition is O(1) and execution achieves near-hand-written performance.

How does this handle ACSets?

It provides specialized navigators like acset_field, acset_where, and acset_parts to traverse and modify category-theoretic databases used in scientific modeling.

Data Science & ML

Provides high-performance, bidirectional data navigation and transformation for Julia collections, S-expressions, and ACSets.

Specter-acset brings the power of Clojure's Specter library to the Julia ecosystem, enabling sophisticated bidirectional data manipulation through a unified lens-like interface. It allows developers to use the same path expressions for both selecting and transforming complex nested structures, including standard Julia collections, typed S-expressions, and category-theoretic ACSets. By utilizing inline caching and continuation-passing style (CPS), it achieves near-hand-written performance, making it ideal for large-scale scientific data processing and symbolic manipulation tasks within the Catlab.jl ecosystem.

Key Features

01Seamless integration with Catlab.jl, DataFrames.jl, and Graphs.jl

02Advanced S-expression navigation for typed AST manipulation

038 GitHub stars

04Bidirectional path expressions for simultaneous data selection and transformation

05Native support for ACSets (Algebraic C-Sets) and categorical databases

06High-performance inline caching and O(1) navigator composition

Use Cases

01Performing deep nested updates on Julia dictionaries and dataframes without boilerplate

02Transforming complex category-theoretic models and graphs in Catlab

03Navigating and rewriting S-expression-based abstract syntax trees (ASTs)
