I need to be able to find a run of characters (like count) in a
string and substitute in the value #{object.count} so that I’m left
with a string that can itself be interpolated. The method for doing
this that jumped out was to use the string’s gsub method like this:
original_string.gsub(/\*count\*/, /count of #{object\.count}/
(Old hands at Ruby are now chuckling, and rightly so) How do I go
about getting the literal text in the substitution portion without
getting an, “NameError: undefined local variable or method `object’
for main:Object”?
Any assistance, pointers or suggestions appreciated.

s = original_string.gsub(/*count*/, ‘count of #{object.count}’)
set object somehow
eval “”#{s}""
