static method call - bug or a feature?

[Michal Hantl]

class TestOffer < Model
...

def self.blank
o = new
...
o
end

end

o = TestOffer.blank()
puts o.getClass.toString() #prints "class models.Offer"

-- Is this a bug or a feature?

(I'm using new-ish Mirah, since the new one breaks my old Dubious (new
Dubious is unusably slow))

Please ls your config dir. What do you see in there?

[Michal Hantl]

Sorry for that mystification, this is the propper code:

class Offer < Model
def self.blank
new
end
end

class TestOffer < Offer
end

o = TestOffer.blank()
puts o.getClass.toString() #prints "class models.Offer"

ls:
michal@domov:~/mystuff/Kyle$ ls config
application.properties asset.properties build.properties

OK, so it mirah slow to compile, or is the dubious app slow to spin-up?

That's how java static methods work. I've got a few ideas for ways we could implement class methods like ruby has, where self is the class you you used to call the method, but nothing is implemented yet. For now your best bet is to copy that method into each subclass.

I did post about speed Issues earlier - 18s lag after changing a view
is way too much.

I'm currently doing Mirah fulltime as a startup and older version of
Dubious works great for me (even though it has some crazy
bugs/features).

I've extended dubious a little (more freedom in controllers, testing
and file uploads) and will try the new one later. (Last time I lost a
dat migrating my app to the new Dubious and back.)

Thats what I thought. Thanks for explenation!

Which books do you recomend to learn Java?
(I'm used to programming in Ruby, JS, PHP did some Haskell and Prolog)

Great, you should sync up with Nick, and get those new features into a fork, and send us a pull request.

The controller compilation step should be much faster once the workaround I added to the Rakefile to deal with some odd compiler behavior in Mirah involving keeping state around in such a way that everything blows up. I'm not sure whether or not the new parser fixes it.

You could try commenting out my workaround and testing it. I plan on getting back to it sometime this week.

The workaround is here http://github.com/mirah/dubious/blob/master/lib/dubious/templates/base/Rakefile#L25

I found a jruby problem that I think was responsible for the issues in your gist nick.  If you build jruby from http://github.com/ribrdb/jruby.git  the issue should be fixed.  Too bad we didn't find this before they released 1.5.3.

Do you mean the Scala-like way? If you use object keyword instead of
the class keyword, it adds suffix "$" to the generated class and
creates a wrapper class without the suffix.
However, I think that there is no way to do it without a leaky
abstraction. The mentioned way requires recompilation of all
subclasses after adding a static method before using it. If it is not
performed, it can be compiled, but it has a different meaning.
