React2FS - React to File System Changes
React2FS is a standalone, cross-platform, file system watcher written in Go. React2FS’s primary use is as development tool to automatically run tests or rebuild a package when a source file changes.
For example, from a Go package directory simply run
react2fs go test and your tests will automatically be run whenever any file is changed.
jack@edi:~/dev/go/src/github.com/jackc/pgx$ react2fs go test PASS ok github.com/jackc/pgx 0.499s 2014/10/04 11:41:04 "./doc.go": CHMOD PASS ok github.com/jackc/pgx 0.443s 2014/10/04 11:47:01 "./hstore.go": CHMOD PASS ok github.com/jackc/pgx 0.499s
React2FS can watch multiple directories and can include or exclude files based on a regular expression. For example, to only run tests when a
.go file changes and ignore other file system events:
jack@edi:~/dev/go/src/github.com/jackc/pgx$ react2fs -include="\.go$" go test PASS ok github.com/jackc/pgx 0.480s 2014/10/04 11:48:23 "./conn.go": CHMOD PASS ok github.com/jackc/pgx 0.487s
