YAML config based script runner.

run-forrest-run

run-forrest-run should be 100% compatible with scriptz.

Installation

npm i -g run-forrest-run

Configuration

The configuration exists of flows and steps. We start of by defining a couple of options and the start flow.

options:
  retry_count: number     # (default: 0) Retry count if exit code > 0
  env: Object             # (default: {}) Additional environment variables
  output_folder: string   # (default: '') A folder for your logs
start:
  ...

The base options that are defined will be used for each step. All the environment variables from the base options will be used, if it is set. If it is also defined on the step level, then the object will be merged.

arguments: Array<String>    # (default: []) Additional arguments
cwd: string                 # (default: process.cwd()) CWD of the script
