## 项目历史与用法

hwatch is a modern replacement for the Unix `watch` command. It repeatedly runs a command, keeps output history, shows diffs, can log results as JSON, and can trigger hooks when output changes.

### 项目历史

The GitHub repository was created in February 2018, and the README describes hwatch as an alternative watch command developed starting in 2018. The release list shows a v0.1.0 tag in July 2018, followed by 0.1.x releases through 2019 and later 0.2/0.3 releases in 2022.

### 采用历史

The README lists installation paths through Homebrew, MacPorts, AUR, Nix, conda-forge, mise/asdf, Cargo, GitHub release archives, and distro packaging work such as Alpine and Debian-style assets. That spread matches a small terminal utility whose adoption depends on being easy to install on many developer machines.

### 使用方式

hwatch is used where plain `watch` is too stateless: monitoring command output, scrolling previous results, viewing line or word diffs, writing JSONL logs, running an after-command on change, or using batch output in scripts.

### 为什么软件包爱好者会关心

Its package-nerd value is the familiar Unix-watch workflow with persistence and diff awareness. It is a small tool, but it fills a practical gap for people who inspect build output, service state, queue depths, or logs from a terminal.

### 时间线

- 2018: Repository created and v0.1.0 release published.
- 2019: 0.1.x releases continued the early CLI line.
- 2022: 0.2.x and 0.3.x releases appeared.
- 2026: README packaging notes listed multiple package-manager and release-asset paths.

### Related projects

- hwatch is directly related to the traditional Unix `watch` command, terminal diff viewers, JSONL logging workflows, Rust/Cargo packaging, and shell hook automation.

### 来源

- Project README, GitHub release metadata, GitHub repository metadata, and Homebrew package metadata were used.
