Method: Liquid::Template#render

Defined in:
lib/liquid/template.rb

#render(*args) ⇒ Object

Render takes a hash with local variables.

if you use the same filters over and over again consider registering them globally with Template.register_filter

if profiling was enabled in Template#parse then the resulting profiling information will be available via Template#profiler

Following options can be passed:

* <tt>filters</tt> : array with local filters
* <tt>registers</tt> : hash with register variables. Those can be accessed from
  filters and tags and might be useful to integrate liquid more with its host application
