script = '''
if ($lightSensor > 20) {
  say("It's daytime now!")
}
'''

def lightSensor():
    return read_light_sensor_port()

compiler = EveScriptCompiler()
compiled_script = compiler.compile(script)

executor = EveScriptExecutor({
    'actions': { 'say': lambda x: print(x) },
    'variables': { '$lightSensor': lightSensor },
})

executor.run_script(compiled_script)
# Out: It's daytime now!

EveScript allows you to write simple event-based scripts that evaluate various conditions and execute actions. The conditions and actions are highly customizable to maximize the flexibility. EveScript can be used in embedded systems (such as Raspberry Pi) to implement a flexible event-based system.
