File Watcher uses https://github.com/go-fsnotify/fsnotify to watch the filesystem and execute a command when a file changes.
go get github.com/dnephin/filewatcher
Run go tests

See filewatcher --help
Excludes
File globbing patterns are used to match files, with one addition.
See https://golang.org/pkg/path/filepath/#Match for the standard file matching
rules. Exclude paths may also use a **/ prefix, which matches the pattern
against any directory. This may be used to ignore files with a specific
extension that may occur in any directory in the hierarhcy.
Commands
Commands may include variables in the form ${variable} which will be
replaced with a value based on the file that was modified. Supported
variables are:
filepath- the relative path to the file that changeddir- the directory of the file that changedrelative_dir- the directory of the file that changes with a ./ prefix
These values are also set as environment variables for the process:
TEST_FILENAME- the relative path to the file that changedTEST_DIRECTORY- the relative path to the directory of the file that changed
