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. ### Timeline - 2023: GitHub repository created. - 2023: Early v0.1.x releases published. - 2023: v0.7.7 published and tracked by Homebrew. ### Related projects - The README directly compares fastgron with gron and mentions jq and jj in path-query benchmarks. ### Sources - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** fastgron - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Other Package-Manager Records - Nix - fastgron: normalized package name match | nixpkgs package indexes: pkgs/by-name/fa/fastgron/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://pkg.so/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://pkg.so/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://pkg.so/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://pkg.so/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [cmake](https://pkg.so/brew/cmake/) - Build dependency declared by Homebrew. - [remarshal](https://pkg.so/brew/remarshal/) - Shares pkgdb curated category or tags: cli, data-conversion, developer-tools, json. - [json-glib](https://pkg.so/brew/json-glib/) - Shares pkgdb curated category or tags: cli, developer-tools, json. - [ascii2binary](https://pkg.so/brew/ascii2binary/) - Shares pkgdb curated category or tags: cli, data-conversion, developer-tools. - [json2tsv](https://pkg.so/brew/json2tsv/) - Shares pkgdb curated category or tags: cli, data-conversion, developer-tools, json. - [sbjson](https://pkg.so/brew/sbjson/) - Shares pkgdb curated category or tags: cli, developer-tools, json. - [python-yq](https://pkg.so/brew/python-yq/) - Shares pkgdb curated category or tags: cli, data-conversion, developer-tools, json. - [yj](https://pkg.so/brew/yj/) - Shares pkgdb curated category or tags: cli, data-conversion, developer-tools, json. - [dhall-yaml](https://pkg.so/brew/dhall-yaml/) - Shares pkgdb curated category or tags: cli, data-conversion, developer-tools. - [dhall-toml](https://pkg.so/brew/dhall-toml/) - Local package facts share a topical domain.
