## Project history and usage

fsevent_watch is a small macOS command-line client for watching filesystem events through Apple's FSEvents facility. Its README describes it as a standalone fork of the C tool inside rb-fsevent, focused on usability and composability with other tools.

### Project history

The project is intentionally compact: the GitHub repository shows a C and Makefile codebase with a small commit history. Its upstream README emphasizes parseable tab-delimited output and line buffering, making it easy to compose with tools such as grep, xargs, make, and Markdown renderers.

The lone GitHub release, v0.2, was published in January 2021 for macOS 11+ support.

### Adoption history

Homebrew packaging gives fsevent_watch a simple install path for users who want raw FSEvents output without embedding a Ruby gem or larger watcher framework. Its niche is macOS-only development automation and file-change scripting.

### How it is used

The README examples pipe `fsevent_watch -F` into line-buffered filters and `xargs` to rebuild C files or regenerate Markdown output. The tool does not document a config or credentials file; it is used directly from shell pipelines.

### Why package nerds care

fsevent_watch is package-nerd relevant because it is a tiny single-purpose wrapper around a platform API. It fills the gap between high-level cross-platform file watchers and macOS's native event stream, which is exactly the kind of utility Homebrew keeps discoverable.

### Timeline

- 2021: v0.2 was released with macOS 11+ support.

### Related projects

- rb-fsevent is the upstream Ruby-related project whose C tool was forked into fsevent_watch.
- Apple FSEvents is the macOS filesystem-event API that the tool exposes.
