## Project history and usage

arelo is a small Go command-line utility for restarting a command when watched files change. Its official README frames it as a simple live-reload tool with glob-based matching, safe child-process termination, no config file, and no local server requirement.

### Project history

The GitHub repository was created in April 2020, and the first GitHub release, v1.0, was published later that month. The project has stayed intentionally narrow: it watches target paths, filters filesystem events, and re-runs an arbitrary command rather than becoming a language-specific development server.

### Adoption history

Homebrew packages arelo as a formula built from the upstream GitHub tags, and the upstream README documents installation through Go, Homebrew, or release binaries. The adoption story is therefore mostly package-manager convenience for developers who want one binary in PATH rather than a framework-specific watcher.

### How it is used

Typical usage is to run arelo with one or more glob patterns and a command after `--`, for example watching Go source and HTML files and restarting `go run .`. The README also documents polling mode for environments where filesystem notifications are unreliable, such as WSL2.

### Why package nerds care

arelo matters as a deliberately boring watcher: it is cross-project, does not own a TCP port, and avoids project config. For package-manager users, that makes it a compact alternative to heavier live-reload stacks when the desired behavior is just 'restart this command when these files change.'

### Timeline

- 2020: GitHub repository created.
- 2020: v1.0 published as the first GitHub release.
- 2025: v1.15.x releases continue the small single-binary watcher line.

### Related projects

- The README lists realize, fresh, gin, and go-task as similar projects, positioning arelo among Go-era file watchers and task runners while keeping the implementation generic enough to run any command-line tool.
