Overview

The InterpolationCompiler module contains optimizations that can tremendously speed up the interpolation process on the Simple backend.

It works by defining a pre-compiled method on stored translation Strings that already bring all the knowledge about contained interpolation variables etc. so that the actual recurring interpolation will be very fast.

To enable pre-compiled interpolations you can simply include the InterpolationCompiler module to the Simple backend:

I18n::Backend::Simple.include(I18n::Backend::InterpolationCompiler)

Note that InterpolationCompiler does not yield meaningful results and consequently should not be used with Ruby 1.9 (YARV) but improves performance everywhere else (jRuby, Rubinius).

.reserve_key(key) ⇒ Object

Marks a key as reserved. Reserved keys are used internally, and can’t also be used for interpolation. If you are using any extra keys as I18n options, you should call I18n.reserve_key before any I18n.translate (etc) calls are made.
