I just heard of Chronic and wanted to integrate it with Highline so i
could get natural language dates like "yesterday", "tomorrow" etc.

I find that I get a nil returned if I do:

dob1 = ask("DOB? ", Chronic)

However, if i try this it works:

class NameClass
def self.parse( string )
Chronic.parse(string)
end

end

dob = ask("Date? ", NameClass)

Looking thru source reveals that :

elsif [Date, DateTime].include?(@answer_type) or
@answer_type.is_a?(Class)
@answer_type.parse(answer_string)

Now Chronic is a module not a class. So i guess in this case no part of
the "case" was called.
Now my question is:
1. Should there be a respond_to in the Highline case, or perhaps a check
for module also ?

2. Is there anyway i can do this in one line without modifying highline,
and without creating a separate class. Is there some block method or
param i could use to invoke Chronic.parse ?

thanks.

You could use a proc object


# test.rb
require 'rubygems'
require 'highline'
require 'chronic'

hl = HighLine.new

dob1 = hl.ask("DOB? ", proc{|x| Chronic.parse(x)} )

p dob1

That may be a better approach. If you have the time, fork the project on Github and work out a patch for it so we can see how that looks.
