## プロジェクトの歴史と使われ方

termbg is a Rust library and small check program for detecting a terminal's background color. The README says it reports either RGB values or a dark/light theme.

### プロジェクトの歴史

The GitHub repository was created in November 2020, and its v0.1.0 tag points to the initial repository work from the same day. The project has remained a focused terminal-behavior utility rather than a broad terminal UI framework.

### 採用の歴史

termbg is published as a Rust crate and appears in package-manager metadata for Homebrew, dnf, and Nix. Its README badges link crates.io and docs.rs, and its Homebrew formula exposes the included `termbg` executable for checking terminal behavior from the command line.

### 使われ方

Rust programs depend on the crate and call functions such as `terminal`, `rgb`, and `theme` with a timeout. The README also documents an example check program that prints the terminal type, detected RGB value, and dark/light theme.

### パッケージ好きにとっての重要性

termbg is useful in the terminal-tooling niche because theme-aware CLIs often need to know whether the background is dark or light. Its README documents support and non-support across many terminals, which gives package maintainers and CLI authors a compact compatibility reference.

### タイムライン

- 2020-11-09: GitHub repository created and v0.1.0 tag commit dated.
- 2024-11-15: v0.6.1 tag commit dated.
- 2025-01-06: v0.6.2 tag commit dated.

### Related projects

- The README's compatibility list includes Alacritty, GNOME Terminal, GNU Screen, kitty, iTerm2, macOS Terminal, mintty, tmux, Visual Studio Code, xterm, Win32 console, and several unsupported terminals such as Cmder, ConEmu, PuTTY, QTerminal, and Windows Terminal.
