bump for release

1.0

Release note

Function call without parenthesis

When calling functions, you can now omit the parenthesis, like in Groovy

println "Without parenthesis" // println("Without parenthesis")
println fibonacci 10 // println(fibonacci(10))

Iterable operations

Implemented a new syntax to perform common operations on Iterables.

list<int> list = [1, 2, 3, 4]
list<int> list2 = [for int i in list -> i + 1] // map -> [2, 3, 4, 5]
list<float> list2 = [for int i in list -> i + 0.1f if i <= 2] // map and filter -> [1.1f, 2.2f]

println(when int a in list |> a >= 3) // any -> true
println(when int a in list &> a >= 3) // all -> false
println(!when int a in list |> a >= 3) // not any -> false
println(!when int a in list &> a >= 3) // not all -> true

println(when int a in list -> a % 2 == 0) // find -> 2
println(when int a in list -> a % 2 == 5) // find -> null

Map m = [foo: 1, bar: 2]
for ((String key, int value) in m) println("$key=$value")

Full doc here.

Single statement functions

Varargs method calls

You can now call varags method as you would in Java

String.join(",", "s1", "s2") == String.join(",", ["s1", "s2"] as CharSequence[])

String.join(",") == String.join(",", [] as CharSequence[])

Meta annotations

Marcel now brings in its standard library useful annotations allowing to generate boiler-plate code (see full doc here)

it provides 3 meta-annotations

• @stringify which autogenerates an object's toString method based on its properties
• @data which autogenerates the equals and hashCode methods based on the object's properties
• @comparable which makes the object implement Comparable and use its properties to make the comparison
• @lazy which makes the annotated property lazy (lazy initialization)
• @cached which caches the results of the annotated method using the method arguments as the cache key

0.0.2

New features

• instanceof operator

0.0.1
