Do I need to install anything for this skill to work?

Yes, it requires ast-grep (sg) to be installed on your system. You can install it via Homebrew using 'brew install ast-grep' or other package managers.

What programming languages are supported?

It supports a wide range of languages compatible with ast-grep, including JavaScript, TypeScript, Python, Go, Rust, C++, and many others.

How is this different from a standard find-and-replace?

Standard find-and-replace uses text or regex, which often leads to 'false positives' in strings or comments. This skill uses Abstract Syntax Trees (AST) to understand the code structure, ensuring it only changes the specific logic you intended.

Can I preview changes before they are applied?

Absolutely. The skill workflow encourages running patterns without the update flag first, or using the interactive (-i) flag to approve changes one by one.

Performs structure-aware bulk code transformations and large-scale refactoring using AST-based pattern matching.

Jelly Bulk Edit empowers developers to execute safe, large-scale codebase modifications by leveraging the power of ast-grep. Unlike fragile string-based find-and-replace, this skill understands code structure (AST), allowing for accurate semantic transformations such as migrating legacy syntax, updating logging frameworks, or enforcing new coding standards across thousands of files without breaking application logic. It is an essential tool for modernization projects and maintaining consistency across complex repositories.

Características Principales

01AST-based semantic pattern matching for high-precision replacements

02Pre-configured recipes for common refactors like CommonJS to ES6 migrations

03Multi-language support including JavaScript, TypeScript, Python, and Go

040 GitHub stars

05Interactive preview mode to verify changes before applying them

06Wildcard and meta-variable support for capturing complex code structures

Casos de Uso

01Migrating a large codebase from legacy var declarations to modern const/let syntax

02Upgrading API calls or library imports globally following a major version breaking change

03Standardizing logging across a project by replacing all console.log calls with a custom logger
