history
Project history and usage
fastgron is a C++20 JSON-to-GRON converter focused on making large JSON documents grep-friendly at high speed.
Project history
The GitHub repository was created in May 2023. The official README presents fastgron as a high-performance implementation inspired by gron, using simdjson and offering conversion in both directions between JSON and gron-style assignment output.
Adoption history
The README documents installation through Arch, Homebrew, Nix, and downloadable release binaries for Ubuntu and Windows. Homebrew's formula currently tracks the upstream v0.7.7 release archive.
How it is used
Typical use pipes JSON from files, stdin, or URLs into fastgron, filters the assignment-style output with tools such as grep or ripgrep, and can reconstruct JSON with --ungron.
Why package nerds care
fastgron matters to CLI package users because it is a performance-oriented reimplementation of a familiar data-inspection workflow: flatten JSON, use ordinary text tools, and optionally round-trip back to JSON.
