[F-Script-talk] array transformation

[Jonathan 'W. R. <ni...@re...>]

Greetings all,

I have an array of strings representing dates. I'd list to transform it 
into an array of NSDates. I currently have:

> a := {'7/26/04 7:35:00 PM', '7/27/04 11:33:00 AM'}
> [:e|NSDate dateWithNaturalLanguageString:e] value:@a

This works, but is there a way to express this as a message send? 
Something like:

a [:e|NSDate dateWithNaturalLanguageString:e]

Failing really elegant syntax, about about something Smalltalkish like:

a do:[:e|NSDate dateWithNaturalLanguageString:e]

Expressing such things as message sends in as direct a fashion as 
possible was always the goal of HOM, so it should be no surprise that 
it works directly:

	[[NSDate collect] dateWithNaturalLanguageString: [dateStringArray 
each]];

And yes, the last time I checked, HOM worked through F-Script.

Cheers,

Marcel

Hi Jonathan,

What you are looking for is:

NSDate dateWithNaturalLanguageString:@a
