About:
Wrangler is a refactoring tool specifically designed for Erlang/OTP codebases. It provides program analysis and transformation capabilities to safely perform complex code changes like function extraction, module splitting, and pattern refactoring. The tool integrates directly with development environments like Emacs and Eclipse to bring automated refactoring safety to Erlang development.

Key Features:

Automated refactoring transformations for Erlang code
Integration with Emacs and Eclipse IDEs
Program analysis for safe code restructuring
Supports function extraction and module splitting
Pattern-based refactoring capabilities

Use Cases:

Restructuring large Erlang codebases safely
Automating repetitive code changes across modules
Extracting reusable functions from complex code blocks
Splitting monolithic modules into smaller, focused units

Alternatives:

ErlangLS – Language server providing basic refactoring, while Wrangler offers more advanced transformations
Rebar3 – Build tool without built-in refactoring capabilities
