Template:Getalias/doc

Usage
This is a meta-template that is not intended to be transcluded directly from the main article space. It can be used to construct other templates that need to extract the alias value from the specified  structure, so that customized wikilinks can be constructed. For example, → "".

Different parameter values can be extracted using the second unnamed parameter. Use shortname as a second parameter to retrieve the shortname alias value if desired. For example, → "", but  → "". To extract the flag image name (flag alias), use flag as second parameter: &rarr; "". The output defaults to the alias value if the desired xxx alias is undefined in the target template.

A third parameter can specify the variant; for example,  &rarr;  returns the image defined as flag alias-1912 in Country data United States. The variant parameter can also be used to extract the link used with military and sports templates (e.g. army, fb): &rarr;.
