A Ruby extension library implementing multiple algorithms for approximate string matching, searching, and comparison.
amatch is a Ruby extension library that implements multiple algorithms for approximate string matching, searching, and comparison. It provides methods to compute various distance metrics like Levenshtein, Hamming, Jaro-Winkler, and longest common subsequence, enabling developers to perform fuzzy string operations in their Ruby applications.
Ruby developers who need to implement fuzzy string matching, search functionality with typos, data deduplication, or similarity comparisons in their applications.
It offers a comprehensive collection of string distance algorithms in a single, well-integrated Ruby library with a clean API, saving developers from implementing these complex algorithms themselves or using multiple disparate libraries.
Approximate String Matching library
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implements a wide range of string distance metrics including Levenshtein, Hamming, Jaro-Winkler, and more, all accessible through a single library.
Offers a clean API with methods like levenshtein_similar and configurable classes, seamlessly integrating into Ruby codebases.
Allows customization such as setting weights for edit operations in Sellers distance, as demonstrated in the examples.
Available as a gem with simple installation via 'gem install amatch', reducing setup complexity.
Requires compilation during installation, which can lead to build failures on systems without development tools or in restricted environments.
The README provides basic examples but lacks comprehensive API documentation, tutorials, or best practices guides.
Algorithms like Levenshtein have O(n*m) time complexity, making them inefficient for very long strings or high-volume real-time processing.
