Template:Da smw/doc

is a specialised version of da which makes it possible to strip the dab term from SMW tables. In these tables, the normal procedure of using da — which works in other types of SMW output, such as the bulleted list (ul) — fails spectacularly, because SMW itself is creating an unusual kind of link. The standard linked output looks like this: The Eleventh Hour (TV story) For whatever reason, the SMW coders create links in this very redundant way, which means the only solution is to get rid of the second dab term only.

The only recourse is the use of the #sub parser function, with which you can take off a negative number of letters at the end of the string, resulting in The Eleventh Hour Add a closing pair of brackets —  — and your golden!

This is a very different principle, however, to the one on which da works. That template uses a #switch parser function to figure out what kind of page it's on -- (TV story), (comic story), etc. -- and then truncates that specific dab term.

This template doesn't use a #switch at all. Instead it uses a single calculation to figure out the position of the parentheses, and then it eliminates everything from the space before the opening parentheses to the closing parentheses.
