The README presents the project as a deliberately small terminal utility motivated by frustration with semi-broken web-based keyboard testers. ### Adoption history The package reached CLI users through several package-manager channels recorded in the batch input, including Homebrew, Nix, Arch Linux, and Cargo installation. ### How it is used 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. ### Why package nerds care 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. ### Timeline - 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. ### 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:** kbt - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Nix - kbt: normalized package name match | nixpkgs package indexes: pkgs/by-name/kb/kbt/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - pacman - kbt - 2.1.0-1: normalized package name match | Arch Linux sync databases: kbt from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | Keyboard tester in terminal | https://github.com/bloznelis/kbt ## 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. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [pkgconf](https://www.automicvault.com/pkg/brew/pkgconf/) - Build dependency declared by Homebrew. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [kanata](https://www.automicvault.com/pkg/brew/kanata/) - Shares av.db curated category or tags: cli, input, keyboard, system. - [kanata-tray](https://www.automicvault.com/pkg/brew/kanata-tray/) - Shares av.db curated category or tags: cli, input, keyboard, system. - [libxkbcommon](https://www.automicvault.com/pkg/brew/libxkbcommon/) - Shares av.db curated category or tags: cli, input, keyboard, system. - [xkbcomp](https://www.automicvault.com/pkg/brew/xkbcomp/) - Shares av.db curated category or tags: cli, keyboard, system. - [xmodmap](https://www.automicvault.com/pkg/brew/xmodmap/) - Shares av.db curated category or tags: cli, input, keyboard, system. - [bottom](https://www.automicvault.com/pkg/brew/bottom/) - Shares av.db curated category or tags: cli, rust, system, terminal. - [diskonaut](https://www.automicvault.com/pkg/brew/diskonaut/) - Shares av.db curated category or tags: cli, system, terminal, tui. - [eza](https://www.automicvault.com/pkg/brew/eza/) - Shares av.db curated category or tags: cli, rust, system, terminal. ## Combined YAML source View the package source record on GitHub.
