Groovy Intentions in IntelliJ IDEA Community Edition

IntelliJ IDEA Community Edition has a nice feature called intentions. Intentions offer a way to simplify our code. In our editor we can select an intention with Alt+Enter and IntelliJ IDEA shows a popup with available intensions. Let's take a look at some useful intentions when developing Groovy code.

def s = "Simple test ${obj.ide}"   // Becomes: def s = "Simple test $obj.ide"

def output = s != null ? s : ''   // Becomes: def output = s ?: ''

def list = ['a', 'b', 'c'] for (c in list) {     println c.toUpperCase() }   // Becomes: def list = ['a', 'b', 'c'] list.each { c ->     println c.toUpperCase() }

def c = list.getAt(0)   // Becomes: def c = list[0]

def printObj(date, text, list) {     println """         Print on $date $text and list has size ${list.size()}     """ }   // Becomes: def printObj(params) {     println """         Print on $params.date $params.text and list has size ${params.list.size()}     """ }

list.contains('d')   // Becomes: list.contains 'b'

class User { String name } def u = new User() u.setName('mrhaki')   // Becomes: class User { String name } def u = new User() u.name = 'mrhaki'

def s = 'Simple test with ' + obj.ide   // Becomes: def s = "Simple test with $obj.ide"
