history
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.
