Transclusionism

This page documents some of the contraptions at work in this wiki.

How to transclude labeled sections between texts:

To create links between different pages, based on some selection of text that somehow connects the pages on the bases of some common ground:

• Think of a category that is the common ground for the link. (eg. 'rawdata'), formulate it without spaces or using underscores (eg. 'raw_data', not 'raw data' );
• Edit the page and add {{RT|rawdata}}<section begin=rawdata /> before the text selection, and <section end=rawdata /> at the end (take care of the '/', without it doesn't work);
• All the other text selections in other pages which are selected along the same common ground will be transcluded on the side of the text.

How it works:

The section code is used by the 'Labeled Section Transclusion' extension, which looks for the tagged sections in a text, to transclude them into another text based on the assigned labels. The {{RT|rawdata}}<section begin=rawdata /> instead, transcludes the RT Template, substituting the word rawdata in its internal code, in place of {{{1}}}. This is the commented content of Template:RT:

<div class="side">                                          #  Puts the trancluded sections on its own div;
{{#ask:[[Category:{{{1}}}]] |format=array |name=results}}   #  Searches semantically for all the pages in 
                                                            # the requested category, puts them in an array; 
{{#loop: looper                                             #  Starts a loop,
  | 0                                                       #  Going from 0 to
  | {{#arraysize: results}}                                 #  the amount of pages of the array, that:
  | {{#ifeq: {{FULLPAGENAME:                                #   Checks if the pagename
       {{#arrayindex: results | {{#var:looper}}  }}         #   Of the current element of the array
             }} 
  |   {{FULLPAGENAME}}                                      #   Is the same as the page calling the loop,
  | 							    #    In that case it skips it (no selfreference);
  |   {{#lst: {{#arrayindex: results | {{#var:looper}}  }}  #   Searches through the page in the loop for
  | {{{1}}} }}                                              #   All the occurrences of labeled sections
([[{{#arrayindex: results | {{#var:looper}}  }}]])<br /><br /> 
}}
}}</div>[[category:{{{1}}}]]

Necessaire:

Currently on top of MediaWiki and SemanticMediaWiki, the following extensions needed to be installed for the contraption to work:

• Labeled Section Transclusion to be able to select specific sections of the texts and make connections between them;
• Parser Functions to be able to operate statements like if in the wiki pseudo-language;
• Arrays to create lists of objects, for example as a result of semantic queries;
• Loops to loop between the arrays above;
• Variables as it's needed by some of the above.
