proximity v0.1.0

Proximity

Proximity is a tiny program that executes a command when a file or directory has changed. I use it to run a build script when I modify the source for a project I'm working on.

Installation

Proximity requires node.js and npm. Once you have these dependencies, simply:

npm install proximity -g

Usage

The first argument after proximity is the command to run. All following arguments are paths to watch.

For example, the following command will run ./build.sh && ps aux | grep node whenever server.js or static/ are changed.

proximity "./build.sh && ps aux | grep node" server.js static/

Note

Proximity should only be used to run commands that will exit at some point because a separate child process is spawned on each change detected.

TODO

• Catch errors: * File/directory doesn't exist.
• Throttle commands so they don't run multiple times when fs.watch() incorrectly reports multiple changes.
