## プロジェクトの歴史と使われ方

kbt is a Rust terminal keyboard tester whose upstream README expands the name as keyboard tester and frames it as a terminal alternative to online keyboard-test pages.

### プロジェクトの歴史

The repository was created in March 2023 and published release builds during 2023, with 1.0.0 appearing on July 23, 2023 and 2.1.0 on January 6, 2024. The README presents the project as a deliberately small terminal utility motivated by frustration with semi-broken web-based keyboard testers.

### 採用の歴史

The package reached CLI users through several package-manager channels recorded in the batch input, including Homebrew, Nix, Arch Linux, and Cargo installation.

### 使われ方

kbt is run as an interactive terminal UI for checking keyboard input and layouts. The README notes Linux, macOS, and Windows support, a Wayland limitation, and a macOS first-run Accessibility permission requirement.

### パッケージ好きにとっての重要性

For package collectors, kbt is a tidy example of the post-ratatui Rust TUI wave: a small hardware-adjacent diagnostic tool that moved from Cargo-style distribution into mainstream Unix package managers.

### タイムライン

- 2023: Repository created for a terminal keyboard tester.
- 2023-07-23: kbt 1.0.0 release published.
- 2024-01-06: kbt 2.1.0 release published.

### Related projects

- The README credits ratatui as the TUI library used to build the interface.
