Shortcut

{{tlpTemplate:Tlp}}

This is the template link with parameters (or {{tlp}}) template.

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

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

{{tlp|name|parameters}} = {{name|parameters}}

Features of {{tlp}}:

It shows a template name with a link to that template.
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. ({{tlx}}, for instance, uses <code>...</code> text style.)

This template belongs to a whole family of similar templates. See the see also section below for some of them. For instance, when writing documentation you might want to avoid a lot of unnecessary links, since it decreases readability – i.e. on the first occurrence of a template name, use {{tl}}, {{tlp}} or {{Tlx}} and thereafter use {{tlf}}, {{tlc}} or {{tld}}.

Examples

Code	Output	Comments
`{{tlp}}`	{{Template:Template link with parameters/sandbox}}	Shows its own syntax.
`{{tlp\|name}}`	{{name}}
`{{tlp\|name\|first}}`	{{name\|first}}
`{{tlp\|name\|first\|last}}`	{{name\|first\|last}}
`{{tlp\|name\|a\|b\|c\|d\|e\|f\|g\|h\|i\|j}}`	{{name\|a\|b\|c\|d\|e\|f\|g\|h\|i\|j}}	Shows up to eight parameters. The rest are dropped.
`{{tlp\|name\|three\|four}}`	{{name\|three\|four}}	Also shows empty parameters.
`{{tlp\|name\|three}}`	{{name\|three}}	Even shows empty parameters that come at the end.
`{{tlp\|name\|first=a\|last=b}}`	{{name}}	Equal signs are a problem, but there are a couple ways to fix:
`{{tlp\|name\|2=first=a\|3=last=b}}`	{{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.
`{{tlp\|name\|first{{=}}a\|last{{=}}b}}`	{{name\|first=a\|last=b}}	Or, simply use, "{{=}}", the equal-sign template, to "escape" the symbol.
`{{tlp\|name\|2=1=a\|3=2=b}}`	{{name\|1=a\|2=b}}	Both techniques also work with numbered positional parameters (e.g.: "`\|1=`", "`\|2=`").
`{{tlp\|name\|2=1=a\|last{{=}}b}}`	{{name\|last=b}}	The named parameter ("`\|last=`") clobbered the prior one ("`\|2=`"). Again, all subsequent parameters after a numbered parameter must also be numbered...
`{{tlp\|name\|2=1=a\|3=last=b}}`	{{name\|1=a\|last=b}}	... but that's easy to fix, by adding the position number ("`\|3=`") to the last parameter.
