the beauty of Ruby

Code:

<cfscript>
function select(collection,closure) {
var result = structNew();
var e = 0;
for (e in collection) {
if (closure.call(collection[e])) {
result[e] = collection[e];
}
}
return result;
}
</cfscript>

<cfset emps = structNew() />
<cfset e = structNew() />
<cfset e.name = "Sean" />
<cfset e.isManager = true />
<cfset emps[e.name] = e />
<cfset e = structNew() />
<cfset e.name = "Matias" />
<cfset e.isManager = false />
<cfset emps[e.name] = e />
<cfset e = structNew() />
<cfset e.name = "Paul" />
<cfset e.isManager = false />
<cfset emps[e.name] = e />

<cfset mgrs = select(emps,cf.new("e.isManager","e")) />

In Ruby:

Code:

emps = [ {:name => "Sean", :isManager => true},
{:name => "Matias", :isManager => false},
{:name => "Paul", :isManager => false} ]

mgrs = emps.select{|e| e[:isManager] }

Or if isManager was a method in the emp class, the last line could be:

Code:

emps.select(&:isManager)

That's interesting, because CF is one of the easier languages. I wonder what it looks like in Java Very Happy

or .net.

Maybe I should give this Rubby stuff a try. Cool

I "Tried" ColdFusion 3 years ago when I was a HardCore PHP guy and now, I cringe at the idea of even thinking about writing an application in PHP.

Jason, same here in terms of CF and Ruby/Rails. At first I hated Rail's conventions, but when I tried it again, I was sold. CF seems counter-productive, and too expensive.[/quote]
