[simrb]

I am using the slim gem that depends the template, when i run the slim that gets me a error,

.../temple-0.3.4/lib/temple/mixins/engine_dsl.rb:128:in element': Proc or blocks must have arity 1 (ArgumentError) from /home/app/ruby/lib/ruby/gems/1.9.1/gems/temple-0.3.4/lib/temple/mixins/engine_dsl.rb:9:inappend'
from /home/app/ruby/lib/ruby/gems/1.9.1/gems/slim-1.0.4/lib/slim/engine.rb:68:in <class:Engine>' from /home/app/ruby/lib/ruby/gems/1.9.1/gems/slim-1.0.4/lib/slim/engine.rb:4:inmodule:Slim'
from /home/app/ruby/lib/ruby/gems/1.9.1/gems/slim-1.0.4/lib/slim/engine.rb:1:in `<top (required)>'
....

The ruby code as follows

        require "slim"
        Tilt.new['template.slim'].render(scope)
        Slim::Template.new(filename, optional_option_hash).render(scope)
        Slim::Template.new(optional_option_hash) { source }.render(scope)

Interesting. The same failure is on Travis too, but that wasn't until yesterday or so: http://travis-ci.org/#!/judofyr/temple/jobs/405569.

The same failures show up for Slim too: http://travis-ci.org/#!/stonean/slim.

@judofyr: The error you see was due to a api change but is fixed now.

[simrb]

That is working when you fixed it.

I'm just surprised the error was in v0.3.4.

@judofyr: Yes me too.
@coolesting: What was the problem?
