Smalltalk Implementation Finder

About

Analyzes method implementations across Pharo Smalltalk class hierarchies to provide deep insights into a codebase. This skill helps developers trace how abstract methods are implemented in subclasses, discover idiomatic coding patterns, assess the impact of changing a method's signature, and identify refactoring opportunities by finding duplicate code. It is essential for anyone needing to understand, maintain, or extend an existing Smalltalk system by answering questions like "Who implements this method?" or "How is this pattern implemented across the system?".

Key Features

• Discovers common Smalltalk implementation patterns and idioms.
• Assesses the impact of method signature changes by counting implementors and references.
• Filters method references by the specific implementation being called.
• Identifies duplicate or similar code to find refactoring opportunities.
• Traces method implementations across entire class hierarchies.

Use Cases

• Learn how to implement a common method (e.g., 'printOn:') by studying existing examples.
• Determine the risk and effort required before refactoring a core method's signature.
• Find and consolidate duplicated code from multiple subclasses into a single superclass method.
