It can't. Filters are run at compile-time; they don't have access to the execution context. This won't be the case in 2.0, but for now it is.
I agree with other responders that the best solution would be a helper method. You don't need to define it in your Controller class; you could make a Helper module and include it in the eigenclass of the instance, or you could just add a method to Haml::Helpers, which is automatically included. - Nathan Bob Aman wrote: >> Is it possible to dynamically add in a custom filter that would allow >> me to get that :noautoindent functionality? >> >> Bob. >> > > Here's what I came up with: > > module Haml > module Filters > class OneLine > def initialize(text) > @text = text > end > > def render > Haml::Engine.new(@text).render().gsub(/^\s+/, "").gsub(/[\r\n] > +/, "") > end > end > end > end > > Only problem: I'm passing an execution context into the Haml engine, > and I don't have a reference to it within the filter, which means that > my execution context has changed anytime I use the filter.
