literal quote in an array?

Discussion in 'Ruby' started by Simon Schuster, Sep 24, 2007.

  1. using colons for now, but would like to somehow encapsulate a sentence
    in this way (basically), with quotes.

    speaker = ["joe ", "betty "]
    expression = ["said: ", "replied: ", "stated: "]
    content = ["hello.", "bye."]

    053:0> sentence = speaker[0] + expression[1] + content[0]
    "joe replied: hello."
    but I'd like to get:
    "joe replied, "hello.""

    thanks!

    '"hello"'
    %q{"hello"}
    "\"hello\""

  3. This can work if you do not have strange characters in the content:
    sentence = speaker[0] + expression[1] + content[0].inspect

    This is better:
    sentence = speaker[0] + expression[1] + "\"#{content[0]}\""

  4. I'd do it like this:
    speaker = %w(joe betty)
    expression = %w(said replied stated)
    content = %w(hello. bye.)
    sentence = "#{speaker[0]} #{expression[1]}, #{content[0].inspect}"

    If using inspect feels too hackish to you, you could use \"#{content[0]}\"
    instead.

  5. Or better still:

    sentence = %{#{speaker[0]} #{expression[1]} "#{content[0]}"}

    Then you don't need the extra spaces in the speaker and expression
    elements.

    Seeing what you're doing, I thought I'd show you my "String#variation"
    method, that allows you to write a generic sentence like this:
    q = "(How (much|many)|What) is (the (value|result) of)? "
    and generate random variations on it via:
    q.variation

    If you have variables you want to substitute into the string, you can
    either do that during construction (if they never change):
    q = "(Hello|Howdy), #{name}"
    or you can substitute the name variable on the fly:
    q = "(Hello|Howdy), :name"
    greeting = q.variation( :name=>"Bob" )

    I wrote this code for my solution to Quiz #48 [1], and have only ever
    used it there, but it's reasonably simple and seems solid enough.

    class String
    def variation( values={} )
    out = self.dup
    while out.gsub!( /\(([^())?]+)\)(\?)?/ ){
    ( $2 && ( rand > 0.5 ) ) ? '' : $1.split( '|' ).random
    }; end
    out.gsub!( /:(#{values.keys.join('|')})\b/ ){ values[$1.intern] }
    out.gsub!( /\s{2,}/, ' ' )
    out
    end
    end


    Perhaps you will find it useful.

    Oops, I forgot that this relies on having:

    class Array
    def random
    self[ rand( self.length ) ]
    end
    end
