collection extensions
I suggest adding 2 commands:
List list(Object... objs) {
return new ArrayList(Arrays.asList(objs));
}
Map map(Map.Entry... entries) {
Map map = new HashMap();
for( Map.Entry entry : entries ) {
map.put( entry.getKey(), entry.getValue() );
}
return map;
}
And I suggest adding one binary operator => which would create a Map.Entry
. So now we could do things like:
numbers = list( 1, 2, 3 );
numberNames = map( 1 => "one", 2 => "two", 3 => "three" );

Very good idea. this would be very useful.
However I suggest that language enhancements, espeically ones that dont conform
to
java specs, be either defered or in a new fork/branch.

I can see how this syntax would be useful and convenient. However, Beanshell
is a
java-like language, and I don't think that it is such a good idea to be adding
non-java syntax.

I agree that adding a lot of non-java syntax is a bad idea. But the 2 global
methods
I suggested here, list() and map(), are possible without any syntax additions
as long
as we have varargs, which is part of java since jdk 1.5 . The only addition to
syntax which is suggested is a "=>" binary operator to create Map.Entry
objects. And
this is very minor addition, just one more binary operator.

Perhaps another command ("pair(key, value)") would be sufficient?
Than you could do
numberNames = map(pair(1, "one"), pair(2, "two"), pair(3, "threee"));
No new symbols ;)

That works but maybe entry is better than pair() as in:
numberNames = map(entry(1, "one"), entry(2, "two"), entry(3, "three"));
