## プロジェクトの歴史と使われ方

unar packages the command-line side of The Unarchiver/XADMaster: `unar` extracts archive contents and `lsar` lists them. Its history is tied to the Mac utility The Unarchiver, but the CLI became valuable on Unix-like systems because the same engine handles many ordinary, proprietary, old, and obscure archive formats.

### プロジェクトの歴史

The official command-line page explains that The Unarchiver is a macOS app while the underlying unarchiving code can run on other operating systems, exposed through the `unar` and `lsar` command-line tools for macOS, Windows, and Linux.

The XADMaster README describes the engine as an Objective-C library for archive and file unarchiving and extraction. It supports formats such as Zip, Tar, Gzip, Bzip2, 7-Zip, RAR, LhA, StuffIt, Amiga archives, CAB, and LZX; uses libxad for old and obscure formats; and notes that it was originally developed by Dag Agren.

MacPaw's 2017 acquisition announcement says it bought The Unarchiver, promised to maintain it, improve it, and keep it free. The command-line code remained available through the XADMaster repository, with GitHub releases continuing through v1.10.8 in 2023.

### 採用の歴史

The official command-line page documents binary downloads for macOS and Windows and notes Ubuntu 12.04 packages under the package name `unar`. The input package metadata shows wider packaging across Homebrew, Debian, Fedora, MacPorts, Nix, Scoop, Ubuntu, and openSUSE.

In package-manager culture, `unar` spread because archive extraction is a recurring automation problem and the standard base tools do not cover the long tail of RAR, StuffIt, old Mac, Amiga, disk-image, and installer formats.

### 使われ方

`unar` is used when a script or shell user needs extraction; `lsar` is used to inspect archive contents first. The official page gives package-manager installation examples and source build instructions for Linux with GNUstep and compression-library dependencies.

The package is especially useful in archival, reverse-engineering, data-recovery, and media-library workflows where the input archive format is unknown or old. It is less about compression creation and more about robust unpacking.

### パッケージ好きにとっての重要性

unar is a package-nerd favorite because it turns a broad, format-savvy desktop unarchiver into a scriptable CLI. It fills the gap between base `tar`/`unzip` utilities and format-specific tools such as `unrar`.

Its long-tail format support also makes it valuable for reproducible package tests and historical software archives: a package manager can install one tool that understands many weird archives.

### タイムライン

- 2017: MacPaw announces acquisition of The Unarchiver and related technology.
- 2018: MacPaw/XADMaster GitHub repository is created.
- 2018: XADMaster GitHub releases include v1.10.4.
- 2023: XADMaster v1.10.8 is released.

### Related projects

- The Unarchiver is the macOS GUI application using the same underlying unarchiving code.
- XADMaster is the upstream library/repository; libxad and UniversalDetector are related components noted by the official README.
