keepfresh 0.0.2

Filesystem event polling

KeepFresh

A command line interface for polling changes in a directory and either logging or triggering a termination and restart of a provided command. Watchdogs' utility tool watchmedo should be used as opposed to this. This was created due to lack of Watchdog documentation regarding running the tool in CLI with the polling mode.

This was developed for the usecase of hot-reloading in a Docker container where the host has a volume mount in the container.

Currently the provided directory is searched recursively for all file types, with the ability to ignore certain directories.

Installation

pip install keepfresh

Which will install keepfresh as a command.
