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. ### Sources - - ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** fsevent_watch - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Requirements:** macos - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [fsevents-tools](https://www.automicvault.com/pkg/brew/fsevents-tools/) - Shares av.db curated category or tags: cli, file-monitoring, file-watcher, fsevents, macos. - [kqwait](https://www.automicvault.com/pkg/brew/kqwait/) - Shares av.db curated category or tags: cli, file-monitoring, macos, system. - [wait_on](https://www.automicvault.com/pkg/brew/wait-on/) - Shares av.db curated category or tags: cli, file-monitoring, system. - [asitop](https://www.automicvault.com/pkg/brew/asitop/) - Shares av.db curated category or tags: cli, macos, system. - [bluetoothconnector](https://www.automicvault.com/pkg/brew/bluetoothconnector/) - Shares av.db curated category or tags: cli, macos, system. - [blueutil](https://www.automicvault.com/pkg/brew/blueutil/) - Shares av.db curated category or tags: cli, macos, system. - [brightness](https://www.automicvault.com/pkg/brew/brightness/) - Shares av.db curated category or tags: cli, macos, system. - [cliclick](https://www.automicvault.com/pkg/brew/cliclick/) - Shares av.db curated category or tags: cli, macos, system. - [chokidar-cli](https://www.automicvault.com/pkg/npm/chokidar-cli/) - Local package facts share a topical domain.
