M-search

m-search is a multi-threaded file search tool and library for Rust. It searches file names with glob patterns and file contents with regex, walking directories in parallel while respecting .gitignore rules via the ignore crate — so you're not wading through target/ or node_modules/ unless you mean to.

From the terminal it behaves like a focused search utility: point it at a path, give it a pattern, and get matches back quickly on large trees. Flags cover the cases you actually hit — content search (-c), case-insensitive (-i), JSON output for scripting (--json), thread count (-j), and max depth (--max-depth). As a library, the same SearchConfig + search() API drops into other Rust tools when you need programmatic discovery.

The design goal was parallel I/O without pulling in an async runtime. Worker threads chew through the file list; results stream back as they're found. It's not ripgrep — and doesn't try to be — but it's a solid, understandable baseline for "find this string in my repo" or "list every .rs file under src/."

Good for learning how directory traversal, glob matching, and thread pools fit together in a real CLI, and for day-to-day grepping when you want something you own end-to-end.
