Custom template engines about toto HOT 15 CLOSED

Hey, I'm gonna add this feature through a config var probably, but for now, you could alias :index to :blog by adding this code to your config.ru:

class Toto::Site
  alias :blog :index
end

This will make them identical, but will show up as /blog in the url.

Brilliant! That works as a charme... Love this..

Need to polish my Sinatra code-fu, would love to add compass support with haml/sass/blueprint etc.. what's your take on that?

Could it be made extendable so the toto core stay's lean and mean.

Additional preprocessing, like Sass could probably be handled by a Rack middleware — I'm sure someone already wrote something like that.

For templating, I'd have to expose the template engine, which is something I could do pretty easily through a config var, or at least make it really easy to monkey-patch. You can get that functionality right now though by overwriting this:

http://github.com/cloudhead/toto/blob/master/lib/toto.rb#L22-25

by something which calls haml.

cool.. thanks.. I will give it a shot this weekend...

incidently, just pushed 0.2.6, which gives access to @articles from all pages — for your scenario, I still think the alias makes more sense, because /blog is actually the index.

note that @articles is lazy-loading, so it won't load the actual articles until you try to access a property of it.

from toto.

nice!

Found how to use sass :
use Sass::Plugin::Rack

it's already there in the haml gem... :)

And this for Haml processing

module Toto
module Template
def to_html page, &blk
path = (page == :layout ? Paths[:templates] : Paths[:pages])
Haml::Engine.new(File.read("#{path}/#{page}.haml"),:attr_wrapper => '"', :filename => path ).render(binding)
end
end
end

from toto.

nice. I think giving the ability to pass a rendering lambda to the config would be ideal in this case, something like:

set :renderer, lambda do |page| 
    Haml::Engine.new(File.read("#{path}/#{page}.haml"),:attr_wrapper => '"', :filename => path ).render(binding)
end

and then evaluating it in to_html.

could open up lots of possibilities.

I just pushed 0.4.0, which makes this possible through the :to_html setting:

set :to_html, lambda do |path, page, binding| 
    Haml::Engine.new(File.read("#{path}/#{page}.haml"),
                               :attr_wrapper => '"',
                               :filename => path ).render(binding)
end

I haven't tested with Haml specifically, but there's no reason it shouldn't work

from toto.

very nice!! Still haven't had time to finish my webpage with toto, but it's still in the pipeline. This feature is very a very nice addition.

I am trying to switch to Haml rendering and get this with the new code:
config.ru:29:in lambda': tried to create Proc object without a block (ArgumentError) from config.ru:29 from /var/lib/gems/1.8/gems/toto-0.4.0/lib/toto.rb:316:ininstance_eval'
from /var/lib/gems/1.8/gems/toto-0.4.0/lib/toto.rb:316:in `initialize'

from toto.

I am using the config.ru:

set :to_html, lambda { |path, page, binding|
Haml::Engine.new(File.read("#{path}/#{page}.haml"),
:attr_wrapper => '"',
:filename => page ).render(binding)
}

but now Haml barks about things with a trace...

Traceback (innermost first)

The dump of the lamda parameters:
Path blog/templates, page layout, binding #Binding:0x7f47da9b4258

The File object is good.. represents layout.haml

from toto.

ahm, it's just the :filename => page should be :filename => path — I have no idea what that does though.

gonna fix the example.

from toto.

Excellent... Good eye... I missed that too when looking at the Haml docs. Works like a charm. Very nice having Haml templates!! W00t. Thanks!

from toto.

np, just pushed an update to be able to pass blocks instead of lambdas, should be prettier:

set :to_html do |page|
   # do stuff
end
