Convenient logback/slf4j logging closures for Groovy script authors.

slf4jScriptLogging.groovy

@Grab(group='ch.qos.logback', module='logback-classic', version='[1.0.9,)')
import org.slf4j.Logger
import org.slf4j.LoggerFactory
import ch.qos.logback.classic.Level

logger = LoggerFactory.getLogger("yourScript") // or whatever
logger.level = Level.INFO // or whatever

log = { level, msg, Object... args -> logger."${level.toLowerCase()}"((msg ?: "").toString(), args) }

trace = { msg, Object... args -> log("trace", msg, args) }
debug = { msg, Object... args -> log("debug", msg, args) }
info  = { msg, Object... args -> log("info",  msg, args) }
warn  = { msg, Object... args -> log("warn",  msg, args) }
error = { msg, Object... args -> log("error", msg, args) }

Managed to use logging in my groovy script. Thank you for posting this!
