Historique du projet

The fswatch README traces the project to Alan Dipert's 2009 OS X implementation using Apple's FSEvents API. At the end of 2013 Enrico M. Crisostomo wrote fsw as a cross-platform replacement and front end for multiple filesystem event APIs.

In April 2014, the authors of fswatch and fsw agreed to merge the programs, with future development continuing in the fswatch repository under Crisostomo's maintenance. The current README describes fswatch as a frontend for libfswatch, with C, C++, and Go bindings noted.

Historique d'adoption

The official README tells users to obtain fswatch from their operating-system or third-party package manager when available, and gives examples for MacPorts, Homebrew, and FreeBSD pkg. The supplied package data shows packages across Homebrew, Debian, Fedora, MacPorts, Nix, Ubuntu, winget, and openSUSE families.

The project has continued as a packaged command-line utility while also exposing libfswatch for programs that need filesystem events without maintaining per-platform watcher code.

Modes d'utilisation

fswatch accepts paths and streams events for changes to files or directories. Its output can be piped to shell loops or to xargs, and the -o mode supports running one command per batch of changes.

By default fswatch chooses the best available monitor for the platform, while users can select monitors explicitly. The README recommends FSEvents on macOS, File Events Notification on Solaris derivatives, inotify on Linux, the Windows monitor on Windows, kqueue for small BSD/macOS watch sets, and polling as the fallback.

Pourquoi les passionnés de paquets s'y intéressent

fswatch is important to package users because it provides one CLI and one library abstraction over the incompatible filesystem notification APIs that build tools, static-site generators, test runners, and shell automation frequently need.

For maintainers, fswatch is also a classic portability package: it wraps native APIs where possible, keeps a poll fallback, publishes Texinfo/man/PDF/API documentation, and ships through many Unix and Windows package channels.
