Question

I’m working on a script to search through a block of HTML text for %{} signs to replace them with dynamic variables.

For some reason my regex is not working.

str = "<p>%{urgent_personal_confidential}</p>"

regex = /^%\{(.*)\}/
puts str.match(regex)

I am sure its something simple… any ideas on what could be wrong?

Answer 1

Ruby already has that feature built-in into String.

"The quick brown %{animal1} jumps over the lazy %{animal2}" % { :animal1 => "fox", :animal2 => "dog"  }

The result is

"The quick brown fox jumps over the lazy dog"
