Overview

We use Hash#inspect in ExpressTemplates::Markup::Wrapper to reproduce arguments to helpers in the Rails view.

Hash#inspect calls #inspect on values and keys. This allows us to place the resulting string into the view code with a simple substitution or concatenation.

In special cases, however, we might want the argument or one of its keys or values to be the result of evaluating of a ruby expression in the view that does not itself return a String. The result of #inspect is normally a quoted and escaped string which would evaluate to a string in the view. What we want is a simple string of code. Here we provide a method that overrides #inspect in the strings eigenclass to strip off enclosing quotes or unwanted escapes. It shouldn’t bother anybody and it keeps us from doing messy things elsewhere for now.
