I'd like to use enumeration functions to select from a sorted list
where I know that if the select function has passed and then starts
failing (returns false)
This isn't a prime situation for Enumerable but certainly nothing it
can't handle.
Never mind - I just discovered $break in the docs
Really, what documentation covered the $break variable? I've always
considered this as Prototype property and although you can get away
with it in most cases, I'd strongly advise against manipulating that
variable yourself.
I'm not sure what use case you're going for, are you collecting the
items in the array that match or just getting to the max index of
matches and then exiting?
Here is some quick and dirty code of how to work out a situation like
yours with Enumerable methods...
var vocab = [
apples,
apricot,
airplane,
bass,
banana,
bounce,
card,
carry,
cart,
ceasar
];
var myFlag = false;
var myRegex = /^b.*/;
var myFilter = function(val, itr){
if(val.search(myRegex) -1 myFlag == false){
myFlag = true;
}
else if(val.search(myRegex) == -1 myFlag == true){
myFlag = false;
}
return (myFlag val.search(myRegex) -1);
}
var newVocab = vocab.collect(myFilter);
console.log(newVocab);

where I know that if the select function has passed and then starts

additional item will also fail). For example, scanning a sorted array
of strings for strings that start with a regexp - once the regexp has
found matches and then stops matching again, there's no need to
continue.
Is that possible with the built-in functions or should I be looping
over the array myself in this case?
