Question

I installed the CompareRevisionsAddOn. I am able to make it work but was expecting that it would seamlessly replace the existing rdiff. Is there a simple (considering my lack of knowledge of perl etc) way to make it replace rdiff ? My wish is that when I click on the '>' sign displayed at the bottom between the revisions, I should get the output from this add-on, with sidebyside rendition and pattern skin (though I am using dragon skin for the pages)

Answer

Although the CompareRevisionsAddOn was designed in order to replace some parts of the functionality of rdiff, it does not overwrite rdiff by default in any place. This was thaught as a 'security feature' so that nobody could overwrite parts of the original TWiki installation by accident. So you have to make the necessary changes which are appropriate for your particular installation yourself.

Since the links of the '>' signs are hardcoded in the TWiki core, there are generally two ways:

• Either change this hardcoded link: in /twikiinstallation/lib/TWiki/UI/View.pm change 'rdiff' to 'compare' in the line $revisions = "$revisions | <a href=\"%SCRIPTURLPATH%/rdiff%SCRIPTSUFFIX%/%WEB%/%TOPIC%?rev1=1.$i&rev2=1.$j\">></a>"; (around line 225)
• Or in /twikiinstallation/bin rename rdiff to rdiff.orig and compare to rdiff
  However, in this case e.g. the links to 'total page history' do not work as expected anymore, so in the templates for your skin you ashould lso replace the corresponding links with 'rdiff.orig'

In both cases you can set the preference variable COMPARERENDERSTYLE to side-by-side, however it is not yet possible to set a default skin which is different from the topic skin. (Maybe in a later version)

THANK YOU VERY MUCH ! I modified View.pm and got the result I wanted. I think now I am ready to deply it in my office. I added the render and skin in the same line to get the effect I wanted. Thanks again.
