## 项目历史与用法

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.

### 项目历史

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.

### 采用历史

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.

### 使用方式

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.

### 为什么软件包爱好者会关心

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.
