A Groovy Script that uses groovy.lang.Binding to pass arbitrary (named) paramters to another Groovy Script

GroovyScriptRunner.groovy

/* groovylint-disable JavaIoPackageAccess, SystemExit, VariableTypeRequired */

if (args.length < 1) {
  println 'Please provide either the script file path or the script content as a string.'
  System.exit(1)
}

// Check if input is a file path or script content
def scriptInput = args[0]
def scriptFile = new File(scriptInput)

def params = [:]

args.each { arg ->
    if (arg.startsWith('-') && arg.contains('=')) {
        def (key, value) = arg.substring(1).split('=', 2)
        // println " > '${key}' = '${value}'"
        params.put(key, value)
    }
}

def binding = new Binding(params)
def shell = new GroovyShell(binding)

if (scriptFile.exists()) {
  // If it's a file path, read the file and evaluate
  shell.evaluate(scriptFile)
} else {
  // If it's a string (not a valid file path), assume it's script content
  shell.evaluate(scriptInput)
}

use something like this:

groovy .\GroovyScriptRunner.groovy .\path_to_script.groovy -var=boo -with_spaces="something with spaces"

or with inline script content:

groovy .\GroovyScriptRunner.groovy "println huh; println with_spaces" -huh="asdf" -with_spaces="w i t h spaces"
