Editing Template:Namespace detect/doc (section)

== Technical details ==

Namespace "Image" was renamed to "File" on 11 December 2008. This template was updated to understand both names well before that, thus it still works fine. For backwards compatibility it still understands "image" both as a parameter name, such as "image&nbsp;= File page text", and as a value "demospace&nbsp;= image".

If you intend to feed tables as content to the numbered parameters of this template, you need to know this:

[[Help:Template|Templates]] have a problem handling parameter data that contains pipes "<code>|</code>" unless the pipe is inside another template <code><nowiki>{{name|param1}}</nowiki></code> or inside a piped link <code><nowiki>[[Help:Template|help]]</nowiki></code>. Thus templates can not handle [[Help:Table|wikitables]] as input unless you escape them by using the {{tn|!}} template. This makes it hard to use wikitables as parameters to templates. Instead, the usual solution is to use "[[Help:HTML in wikitext|HTML wikimarkup]]" for the table code, which is more robust.

For more technical details, e.g. about copying this template to other projects and CSS-based namespace detection, see {{tl|Main talk other}} and its talk page.
