This is the template link with substitution and parameters (or {{fsnp}}) template.

It can be used in documentation and talk page discussions to show how a substituted template name would be used in code.

Here is how this template looks. Code to the left and actual rendering to the right:

{{fsnp|name|parameters}} = {{subst:name|parameters}}

Features of {{fsnp}}:

• It shows a template name with a link to that template, substituted.
• It shows up to eight parameters.
• It also shows empty parameters. (See examples below.)
• It prevents line wraps in its output.
• It uses normal text style.

Examples

Code	Output	Comments
{{fsnp|name}}	{{subst:name}}
{{fsnp|name|first}}	{{subst:name|first}}
{{fsnp|name|first|last}}	{{subst:name|first|last}}
{{fsnp|name|a|b|c|d|e|f|g|h|i|j}}	{{subst:name|a|b|c|d|e|f|g|h}}	Shows up to eight parameters. The rest are dropped.
{{fsnp|name||three|four}}	{{subst:name||three|four}}	Also shows empty parameters.
{{fsnp|name||three|}}	{{subst:name||three|}}	Even shows empty parameters that come at the end.
{{fsnp|name|first=a|last=b}}	{{subst:name}}	Equal signs are a problem, but there are a couple ways to fix:
{{fsnp|name|2=first=a|3=last=b}}	{{subst:name|first=a|last=b}}	Use numbered parameters to fix it. Here, parameter "|2=" is assigned the string "first=a". Start with #2, since "name" is already in the "|1=" slot. Note that all subsequent parameters after a numbered parameter must also be numbered.
{{fsnp|name|first{{=}}a|last{{=}}b}}	{{subst:name|first=a|last=b}}	Or, simply use, "{{=}}", the equal-sign template, to "escape" the symbol.
{{fsnp|name|2=1=a|3=2=b}}	{{subst:name|1=a|2=b}}	Both techniques also work with numbered positional parameters (e.g.: "|1=", "|2=").
{{fsnp|name|2=1=a|last{{=}}b}}	{{subst:name|last=b}}	The named parameter ("|last=") clobbered the prior one ("|2="). Again, all subsequent parameters after a numbered parameter must also be numbered...
{{fsnp|name|2=1=a|3=last=b}}	{{subst:name|1=a|last=b}}	... but that's easy to fix, by adding the position number ("|3=") to the last parameter.
