|{{{1}}}={{{2}}}
This template simply displays a parameter name between a vertical line and an equal sign, as is seen in template calls. (This is useful in template documentation and in talk page discussions of templates.)
To display a parameter name surrounded by {{{triple-braces}}}
(as would appear in template code), use {{paramref}}
.
This template takes the following parameters:
|1=
(may be empty if second parameter is present): the name of the parameter|2=
(optional if first parameter is present): a corresponding value for the parameter|3=
(optional): additional usage text|req=1
: indicate that the parameter is required|opt=1
: indicate that the parameter is optional{{para|name}}
|name=
{{para|name|req=1}}
|name=
(required){{para|name|opt=1}}
|name=
(optional){{para|opt|1}}
|opt=1
{{para|title|<var>book title</var>}}
|title=book title
{{para||section}}
|section
. This is useful for referring to values of unnamed parameters; note the empty first parameter in the template call.{{para|<var>parameter</var>|<var>value</var>}}
|parameter=value
{{para|=|foo}}
|=foo
{{para|2||''optional'' if first parameter is present}}
|2=
(optional if first parameter is present)When using literal, pre-specified values, simply provide the value (appearance as in example 6). When illustrating hypothetical, variable or user-definable values, use <var>value</var>
(appearance as in example 5), and the same should be done for non-literal, example parameters (as in example 7).
