Hi everybody,
I would like to use ruby2ruby in a caming project, but there seems to
be an incompatibility with camping, ruby2ruby and markaby.
Unfortunately I receive strange Markaby::InvalidXhtmlErrors.
To demonstrate, that only combination of all three components causes
the problem I added the following code. I relies on Markaby and
ruby2ruby only and works fine (a.k.a. as expected).
require "rubygems"
require "ruby2ruby"
require "markaby"
def example(&block)
$mab.pre( block.to_ruby.gsub(/^proc \{\n(.*)\n\}$/m,
''\1''))
end
Markaby::Builder.set(:indent, 2)
$mab = Markaby::Builder.new
$mab.xhtml_strict do
div.literate_markaby! do
example do
1 + 1 == 2
end
end
end
puts $mab.to_s
When I wrap that up in a camping project, which looks the following, I
get an error, when using tag! with arguments.
The Code:
require "rubygems"
require "ruby2ruby"
Camping.goes :Test
module Test
module Controllers
class Index < R ''/''
def get
div.literate_programming! do
example { 1 + 1 == 2 }
end
end
end
end
module Helpers
def example(&block)
pre( block.to_ruby.gsub(/^proc \{\n(.*)\n\}$/m,
''\1''))
end
end
end
It raises "Markaby::InvalidXhtmlError no attribute `href'' on div
elements:" in the line "div.literate_programming! do" . If I
change it
to "div do" it works okay. Also every other way of providing arguments
raises the error (div.class_name, div(:rel => "options"), ...).
I don''t know where the :href attribute comes from and I don''t
know,
why it only appears within camping and not in markaby itself.
Any help would be appreciated. Thanks in advance.
Cheers,
Gregor
Note: I''m using the latest release of camping (1.5.180), markaby (0.5)
and ruby2ruby (1.1.7)
Hi Gregor, I wasn''t able to track the error on Camping side, but it comes from r2r that defines nil.error_missing. 2007/9/27, Gregor Schmidt <ruby at schmidtwisser.de>:> require "rubygems" > require "ruby2ruby"# It works in this case but probably breaks r2r on a larger scale. class NilClass undef method_missing end> Camping.goes :Test > > module Test > module Controllers > class Index < R ''/'' > def get > div.literate_programming! do > example { 1 + 1 == 2 } > end > end > end > end > > module Helpers > def example(&block) > pre( block.to_ruby.gsub(/^proc \{\n(.*)\n\}$/m, ''\1'')) > end > end > end> I don''t know where the :href attribute comes from and I don''t know, > why it only appears within camping and not in markaby itself.Camping overrides [:href,:action,:src] to translate relative links to absolute ones. See Mab at the end of camping-unabridged. -- Cheers, zimbatm

Defining NilClass#method_missing for nothing is not too clever, for a large scale libary IMO. By adding module Test # This is my Camping app - not the test/unit test thing (just a reminder) class Mab def tag!(*g,&b) super end end end the problem is solved. Since I''m not changing any behaviour the code should not have unwanted side effects. Perhaps this gives you an idea, where the real cause of the problem is. At least I''ve got a solution now. Thanks for the help Cheers, Gregor

We can''t start to support each and every hack a library will add to the Ruby core. -- Cheers, zimbatm

What if ruby2ruby relied on the other behaviour? -------------- next part -------------- An HTML attachment was scrubbed...

Sorry, if I was misunderstood with saying> Defining NilClass#method_missing for nothing is not too clever, for a > large scale libary IMO.I was "insulting" ruby2ruby and not camping. So everthing is okay on this side. I solved my particular problem with the combination of caming and ruby2ruby and will not use it for something serious - just academics. I was looking for help, concerning this issue, found it, thankfully, on this list and will post a blog entry tomorrow, so other probably will find it as well.>From my side, everything is okay at this point. Thanks again for thehint. There is nothing I could see, that should be changed inside of caming to allow such a "strange" of standard behaviour. Cheers, Gregor
2007/9/28, Gregor Schmidt <ruby at schmidtwisser.de>:> I was "insulting" ruby2ruby and not camping. So everthing is okay on this side.No problem. You can insult Camping if you want, if at least I get understood. Joking aside, it''s true that ruby2ruby still lacks some maturity but it is an interesting project nonetheless. I have big hopes that one day is will be usable to "platterize" camping.rb -- Cheers, zimbatm

2007/9/28, Gregor Schmidt <ruby at schmidtwisser.de>:> For a none native speaker. Could you give a synonym for "platterize".Sorry, from a non native speaker too. The term was probably badly chosen. I was referring to the action that consist of taking camping-unabridged.rb and create a "platter?" out of it. It is a reference to the visual output that camping.rb gives. -- Cheers, zimbatm
