## プロジェクトの歴史と使われ方

infat is a macOS-native CLI for declaratively managing file-extension, Uniform Type Identifier, and URL-scheme opener associations. It turns a Finder preference chore into a scriptable dotfiles-style command.

### プロジェクトの歴史

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.

### 採用の歴史

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.

### 使われ方

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.

### パッケージ好きにとっての重要性

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.

### タイムライン

- 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.
