Grepfruit – A Ruby Gem for Searching Regex Patterns in Files

March 7, 2025

Introducing a New Ruby Gem: Grepfruit - Search Regex Patterns in Files.

Grepfruit is a Ruby gem for searching text patterns in files with colorized output, making the process more user-friendly than standard tools like grep. It offers options to exclude files or directories, truncate output, and include hidden files. Originally created for CI/CD pipelines to search for TODO comments in Rails apps, it's flexible for a wide range of use cases.
