Question

I have loaded a string with #{variable} references in it. How would I resolve those variables in the string like puts does?

name="jim"
str="Hi #{name}"
puts str        

Instead of puts, I would like to have the result available to pass as a parameter or save into a variable.

Answer 1

you could eval it

name = "Patrick"

s = 'hello, #{name}'
s # => "hello, \#{name}"

# wrap the string in double quotes, making it a valid interpolatable ruby string
eval "\"#{s}\"" # => "hello, Patrick"
