ruby parametrized regular expression
- by astropanic
I have a string like "{some|words|are|here}" or "{another|set|of|words}"
So in general the string consists of an opening curly bracket,words delimited by a pipe and a closing curly bracket.
What is the most efficient way to get the selected word of that string ?
I would like do something like this:
@my_string = "{this|is|a|test|case}"
@my_string.get_column(0) # => "this"
@my_string.get_column(2) # => "is"
@my_string.get_column(4) # => "case"
What should the method get_column contain ?
