ထာမ်ပလိက်:Single digit documentation
Templates {{1}}, {{2}}, {{3}}, etc. warn readers/editors that a typo exists in the page they are reading/editing. If {{Single digit documentation}}
is called, you probably meant the parameter Single digit documentation (as {{{Single digit documentation}}} with triple braces), but in fact only double braces were used, invoking {{Single digit documentation}}. In addition to a warning, it also adds pages to Category:Templates with incorrect parameter syntax. For more information on how template parameters work, see mw:Help:Templates#Parameters.
However, the most problems have been caused by omitting the first brace "{" of a parameter and getting {{Single digit documentation}}}, as invoking Template:Single digit documentation +"}" rather than parameter Single digit documentation. This can be an insidious problem, especially when the transclusion of Template:Single digit documentation is hidden, so that the effect is invisible to the person editing a page. For that reason, Template:Single digit documentation now issues a warning to the user.
With that warning, the prior invisible access to Template:Single digit documentation can now be understood to be a formerly unseen problem coded within a page.
- Note: this will also pick up several variations such as {{Single digit documentation|}} for {{{Single digit documentation|}}} and {{{Single digit documentation}}.
Periodically, people check what-links-here to see if anyone has accidentally invoked Template:Single digit documentation.
