simple question

[anitawa]

hello

I have a string like this

string = "hello -a apple -b butterfly -c cat -d dophin"

i would like to parse the string based on some reg exp so that i can
store it in a variable like so.

valuea = "apple"
valueb = "butterfly"
valuec = "cat"
valued = "dophin"

Could someone help me out.

or a gem called 'OptionParser'. It's like optparse, only, I find, a
lot simpler.

Are you parsing a command line? If so, you might want to consider

Here you go, but I just had to make one change. Instead of having variables
valuea, valueb, valuec..., I put them in a hash called value. Is it absolutely
necessary to have them as you posted?

string.split(/\s-/).each do |v|
v = v.split(/\s/)
value[ v[0] ] = v[1] if v.size == 2
end

So you would have

value["a"] = "apple"
value["b"] = "butterfly"
etc...
