GritQL, a Rust CLI for rewriting source code
Hi everyone! I’m excited to open source GritQL, a Rust CLI for searching and transforming source code. GritQL comes from my experiences with conducting large scale refactors and migrations. Usually, I would start exploring a codebase with grep. This is easy to start with, but most migrations end up accumulating additional requirements like ensuring the right packages are imported and excluding cases which don’t have a viable migration path. Eventually, to build a complex migration, I usually ended up having to write a full codemod program with a tool like jscodeshift. This comes with its own…
GritQL, a Rust CLI for rewriting source code launched on March 20, 2024 with 280 votes, #142 of 4,270 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
GritQL is a Rust command-line tool for searching and transforming source code at scale. It addresses the limitations of both simple grep searches and complex codemod frameworks by providing a middle ground for large-scale refactors and code migrations. The tool allows developers to write sophisticated search and transformation rules without needing to build full codemod programs or work directly with abstract syntax trees, making it suitable for teams conducting substantial codebase changes.

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
