how to generate dynamic regexp pattern from strings?

[Nanyang Zhan]

Hi, Could anyone tell me how to generate regexp pattern from strings?

for example, how to code the return_pattern(str) method?
thanks!

str = "^test|production-(\\d+)"
return_pattern(str) ===> /^test|production-(\d+)/

def return_pattern(str)
?????????????????
end

Regexp.escape string

Actually, Regexp.compile string or Regexp.new string

Regexp.escape avoids interpretation of special characters.
