BurntSushi/ripgrep

Ripgrep is a high-performance text search tool that provides a modular, reusable library for line-oriented searching, regex matching, and file traversal. The system is structured as a collection of independent crates—such as `grep`, `ignore`, and `matcher`—that handle specific aspects of text processing, pattern matching, and directory walking. It supports multiple regex engines, including a PCRE2-based implementation and a custom `regex-automata`-based engine, while also offering indexing capabilities for faster repeated searches. Additionally, the project includes a benchmarking suite to compare its performance against other search tools across various environments.

The project was rebranded from 'fst' to 'ripgrep', featuring a comprehensive repository reorganization into a multi-crate structure and the removal of legacy code. Concurrently, the team established a robust benchmarking suite to compare ripgrep's performance against other search tools across various Linux and macOS environments.

This period focused on refactoring the codebase into a modular architecture by extracting core components like the CLI, search engine, and printer into independent crates. The team also migrated the regex implementation to regex-automata and exposed the search functionality as a reusable library for external consumers.

20 changes

This period focused on significantly improving the user experience and developer tooling by refactoring the CLI argument parsing to support configuration files and shell completions. Simultaneously, the project laid the groundwork for a new indexing system by introducing the `crates/index` crate and associated tests, while also expanding documentation generation and adding fuzz testing for stability.
