webgen users - Sep 2009 - Getting problem in loading the webgen tag extensions on windows and mac machine

Hi,

I am developing some custom tags with webgen.
and included this tag in one of the page files as :-

{largethumbnail: {source: ''../../images/myimage.gif'', width:
265}}

e.g.

--------------------------------------------
class LargeThumbnail

  include Webgen::Tag::Base

  def call(tag, body, context)
        .... some html code here
  end

end

website = Webgen::WebsiteAccess.website
config  = website.config

config[''contentprocessor.tags.map''][''largethumbnail'']
''LargeThumbnail''
config.largethumbnail.source(nil, :mandatory => ''default'')
config.largethumbnail.width(nil)
-------------------------------------------------------

And also including this in ext\init.rb file as :-

require File.join(File.dirname(__FILE__), ''large_thumbnail'')

However, I get the below error on my windows and mac machine:

 WARN -- Invalid parameter ''source'' for tag
''Webgen::Tag::Metainfo'' in
</master_test.en.html>
 WARN -- Invalid parameter ''width'' for tag
''Webgen::Tag::Metainfo'' in
</master_test.en.html>
ERROR -- No value for meta info key ''largethumbnail'' in </
master_test.en.html> found in </master_test.en.html>

Basically it is not able to load the extension file. It is always
looking for the default ''Webgen::Tag::Metainfo''
I tried to debug whether it is getting proper paths in envt variables,
but did not work.
I have ruby 1.8.5 installed on my windows machine.

Would really appreciate your help on this.

Thanks in advance...
Best Regards,
Niranjan

the basic problem is that if you require the file, it is only required
once. However, due to how webgen works the initialisation process is
sometimes done twice. The first time the large_thumbnail.rb file gets
required and the configuration stored in the config variable. However,
the second time Ruby sees that the file has already been required and
does not require it again, therefore the config variable is not
populated.

You can circumvent this problem by

* either using `load` instead of `require`
* or just defining the class in the large_thumbnail.rb file and doing
  the configuration stuff in init.rb.

The second way is how webgen does it interally. All the functionality
is split into different files and the configuration takes place in one
central file called lib/webgen/default_config.rb.

Thanks Thomas !
