Processmon

Process monitor that can run trigger scripts and subsequently restarts the process when files on specified paths are modified. This can be very useful when running a development environment in a Docker container.

To try it out:

cargo build
cd example
../target/debug/processmon processmon.toml

Then save a file in the code directory to trigger a restart.

Installation

Make sure you have a recent version of Rust installed, then run:

cargo install processmon

Configuration

Processmon is configured by a toml file:

paths_to_watch = ["code"]

[processes]

[processes.process1]
command = "sh"
args = ["process1.sh"]

[triggers]

[triggers.trigger]
command = "sh"
args = ["trigger.sh"]

command sets the command to run. Place one or more paths to watch in paths_to_watch. triggers sets a list of commands that will run before every restart of the main command. When running a trigger the env var TRIGGER_PATH will be filled with the path that triggered the restart.
