It turns a Finder preference chore into a scriptable dotfiles-style command. ### Project history The project appeared publicly in 2025 and moved quickly through alpha, beta, and 1.x releases. The README describes it as a single-binary macOS-first tool built around NSWorkspace, Launch Services, and UTType, with TOML configuration for extensions, types, and schemes. The release notes show a notable rewrite at version 3.0.0 in September 2025, moving the implementation to Rust and adding URL-scheme inspection support. The README later notes that GitHub became a mirror while development management moved to Tangled. ### Adoption history Adoption is narrow but natural for the Homebrew audience: infat is aimed at macOS power users, administrators, and dotfile maintainers who want repeatable default-app settings across machines. The input package metadata shows Homebrew and Nix packaging. ### How it is used Users run infat info to inspect openers, infat set to bind an app to an extension, type, or URL scheme, or provide a TOML config at $XDG_CONFIG_HOME/infat/config.toml. That makes it useful in setup scripts for default browsers, editors, image viewers, mail handlers, and other app-association preferences. ### Why package nerds care infat is interesting as a small package because it wraps a very platform-specific macOS preference surface in a package-manager-friendly CLI. It sits beside older tools such as duti, but adds URL schemes and a declarative TOML workflow that fits dotfiles culture. ### Timeline - 2025: Public repository created for infat. - 2025: Alpha, beta, and 1.0 releases published in March and April. - 2025: Version 3.0.0 release notes describe a complete rewrite to Rust. - 2026: Version 3.1 release published. ### Related projects - duti is named by the README as an inspiration. macOS Launch Services, NSWorkspace, and Uniform Type Identifiers are the platform APIs that define the problem space. Nix and Homebrew are the package-manager channels reflected in the input metadata. ### 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:** infat - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Requirements:** macos - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - infat: normalized package name match | nixpkgs package indexes: pkgs/by-name/in/infat/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Homebrew utility packages](https://www.automicvault.com/pkg/brew-utility-packages/) - Matched Homebrew package provider. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [defaultbrowser](https://www.automicvault.com/pkg/brew/defaultbrowser/) - Shares av.db curated category or tags: cli, default-apps, macos, system. - [dark-mode](https://www.automicvault.com/pkg/brew/dark-mode/) - Shares av.db curated category or tags: cli, macos, system. - [devcockpit](https://www.automicvault.com/pkg/brew/devcockpit/) - Shares av.db curated category or tags: cli, macos, system. - [duti](https://www.automicvault.com/pkg/brew/duti/) - Shares av.db curated category or tags: cli, default-apps, macos, system, url-schemes. - [fileicon](https://www.automicvault.com/pkg/brew/fileicon/) - Shares av.db curated category or tags: cli, macos, system. - [launch](https://www.automicvault.com/pkg/brew/launch/) - Shares av.db curated category or tags: cli, macos, system. - [m-cli](https://www.automicvault.com/pkg/brew/m-cli/) - Shares av.db curated category or tags: cli, macos, system. - [mas](https://www.automicvault.com/pkg/brew/mas/) - Shares av.db curated category or tags: cli, macos, system. ## Combined YAML source View the package source record on GitHub.
