A simple tool that loads a list of paths to watch from a TOML file. ```toml [[watch]] name = "print hello" path = "src" command = "echo $EVENT_PATH"
[[watch]]
name = "compile sass"
path = "sass/*.sass"
command = "sassc -t compressed sass/style.scss static/style.css"
``
On a change in thepath, it executes thecommand. Directories are watched recursively.
Paths can also be specified with [globs](https://docs.rs/glob/0.3.0/glob/struct.Pattern.html).
Any shell command can be used, along with pipes and so on.
By default, the shell specified in the$SHELLenvironment variable is used to parse and execute the command.
Otherwise, on Unix system, it invokes the default
Bourne shell (shcommand), on windows [cmd.exe](https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/cmd).
Additionally, each command gets the$EVENT_PATH` environment variable, containing the path that changed.
Using notify crate, which provides efficient event handling support for the most operating systems (apart from BSD).
