Overview
Polyglot Piranha is a flexible multilingual structural search/replace engine that allows users to apply chains of interdependent structural search/replace rules for deeper cleanups. Polyglot Piranha builds upon tree-sitter queries for expressing the structural search/replace rules.
This is the higher level architecture of Polyglot Piranha.
At its heart, Polyglot Piranha is a structural find/replacement (rewrite) engine and pre-build language specific cleanup rules like - like simplifying boolean expressions, simplifying if-else
statements, deleting empty class, deleting files with no type declarations, inline local variables, and many more.
A user provides :
- A set (or, a graph) of structural find/replace rules
- Path to the code base
- Arguments to modify Piranha's behavior (like deleting associated comments).
