Template:Var

<noinclude>{{TagSyncPage}}
</noinclude><includeonly>{{#if:{{{1|}}}|{{{1|}}}|{{{2|}}}}}</includeonly><noinclude>{{Tlx|var}} is used on templates such as the infobox templates, and the summaryboxes which give out a pre-formatted set of parameters to display default values properly. Because the pre-formatted set of parameters sets out the variable names using the default value in the form <code><nowiki>{{{var|default}}}</nowiki></code> does not work because even if the value is not used the parameter is still named in the template. Using this template a default can be told to show not only when the value is not set, but also if the value is left blank.

==Usage==
 {{Tlx|var|''variable''|''default value''}}

* ''variable'' is the normal variable used. Be sure to use the | to set the default to nothing so that removing the parameter from the inclusion won't affect the way things are displayed (i.e. use <nowiki>{{{1|}}}</nowiki> for example).
* ''default value'' is the default value to be outputed, this would normally be what you would put after the | in a variable call.
* If ''variable'' is set to some value then ''variable'' will be outputted.
* If ''variable'' is unset, or set to nothing but whitespace then ''default value'' will be outputted.
