I'm wanted to make a "global" module that I could include in my
application for some shared code between them. I've been making
several camping apps and wanted them all to share a helper/partial
that contained the navigation.
I think the root of the "problem" is the way the app modules are
loaded into the Markaby rendering context:
module Views; include Controllers, Helpers end
class Mab < Markaby::Builder
include Views
def tag!(*g,&b)
h=g[-1]
[:href,:action,:src].each{|a|(h[a]=self/h[a])rescue 0}
super
end
end
Here's a slightly unnerving hack which seems to solve the problem.
You pass it the base module (or symbol of) your Camping app and one
or more shared helper modules, and it'll inject them into your
Camping app. (Obviously the symbol parameters won't work if you have
nested modules...you'll have to pass in the module constant
instead...the symbols are just syntactic sugar to echo Camping.goes().)
class TentSteak
def self.bootstrap(mod_or_sym, *appmods)
@@rootmod = mod_or_sym.instance_of?(Module) ? mod_or_sym :
const_get(mod_or_sym.to_s)
inject appmods
end
def self.inject(*mod_or_syms)
@@rootmod.module_eval "class Mab < Markaby::Builder; include #
{mod_or_syms.join(', ')}; end"
end
def self.view_method_defined?(meth)
@@rootmod::Mab.method_defined?(meth)
end
end
Usage is like this:
Camping.goes :MyApp
TentSteak.bootstrap :MyApp, :MyHelperModule, :MyOtherHelpers
I'd love to hear if there's a better way to do this injection. Seems
pretty hacky. Incidentally, TentSteak is a Camping helper library
I've been working on recently. I'll upload it to rubyforge as soon
as I get the ugly corners chiseled off and properly tested/
documented....
