Program Description

This program is a utility for running arbitrary commands when files change. It is written in Rust and is similar to the entr tool.

The program takes a list of paths to watch for changes from stdin. When any of the watched files are modified, the program executes a provided command.

The program supports the following options:

• -c or --clear: Clears the screen before running the command.
• -r or --reset: Reloads a persistent child process.

The program uses the notify crate to watch for file changes and the structopt crate for command line argument parsing.

Usage

To use the program, you can pipe a list of paths to watch from stdin and provide a command to execute when the files change. For example:

echo "my-folder" | rentr -c -r echo "my-folder has changed"

This will watch the my-folder directory for changes and execute the command echo "my-folder has changed" whenever a change occurs.

find . | grep \.rs | rentr -c cargo build `find . | grep .rs | rentr -c echo "CHANGED"
