Hi,
I have a DSL where I want to pass named arguments like follows:
def foo(String a, String b, String c, Closure d) {
}
foo(a=“a”, c=“c”, b=“b”) {
}
I’m aware that named arguments are supported by receiving the arguments with a
map:
def foo(Map<String, String> obj, Closure c) {
}
foo(a:"a", c:”c", b:”b") {
}
The problem with this approach is that for a user of this DSL, it is not
obvious which parameters are expected and what their names are (beside
documenting it, but who is going to read that ;-)).
How can I achieve named function arguments with “real" syntax in Groovy? Is
there an alternative to using maps for this?
By the way, I think it is kind of misleading for a beginner that the following
compiles but does not pass the arguments in the intended order:
foo(a="a", c=“c", b=“b") {
// a == a, b == c, c==b
}
Is this intended behaviour?
Thanks in advance,
Michael
