Template:Parameter typo documentation/summary

{{Refn|name=wrong| Show template documentation

Templates {{tl|1}}, {{tl|2}}, {{tl|3}} etc warn readers/editors that a typo exists in the page they are reading/editing. If {{tnull|}} is called, you probably meant the parameter (as {{{  }}} with triple braces), but in fact only double braces were used, invoking {{  }}. In addition to a warning, it also adds pages to Category:Templates with incorrect parameter syntax.

However, the most problems have been caused by omitting the first brace "{" of a parameter and getting {{ }}}, as invoking Template: +"}" rather than parameter. This can be an insidious problem, especially when the transclusion of Template: is hidden, so that the effect is invisible to the person editing a page. For that reason, Template: now issues a warning to the user.

With that warning, the prior invisible access to Template: can now be understood to be a formerly unseen problem coded within a page.


 * Note: this will also pick up several variations such as {{ {{{1}}} |}} for {{{ {{{1}}}| }}} and {{{ {{{1}}} }}.
