Template:Template link null

Template documentation[view] [edit] [history] [purge]

This template, often abbreviated as {{tnull}}, is used to provide stylized formatting to template displays without actually using the template itself. The code generated will be displayed inline. For a multi-line output, see {{tj}}. To line wrap the code appropriately, see {{tji}}.

Parameters

With the exception of alttext, the named parameters are toggles that are either omitted (default in most cases) or activated (by being assigned a value such as "on", "yes", "true", "include", etc.). They may be included in any order (see Examples below). Certain templates have the parameter "on" by default; see the main table for all alternate options. If a row renders identically to a previous row, it means the current template does not support that option and {{tlg}} needs to be used instead.

Parameter	Action	Use with {{example}}	Default active
	Default (without accessory parameters)	{{example}}
brace	Include braces as part of the template link	example	{{tlw}}/{{tn}}
braceinside	Include innermost braces as part of the template link	example
bold	Renders the template link/name in bold	{{example}}	{{tlb}}, {{tlxb}}
code	Display output using HTML <code>...</code> tags (monospaced font)	{{example}}	{{tlc}}, {{Template link expanded}}, etc.
italic	Display any parameters accompanying the template link/name in italics	{{example|param}}	{{tlxi}}
kbd	Display output using HTML <kbd>...</kbd> tags (monospaced font)	{{example}}
nolink	Don't render the template name as a link	{{example}}	{{tlf}}, {{tnull}}
nowrap	Prevent the insertion of line breaks (word wrap) in the output	{{example}}	{{tlf}}, {{tlp}}
nowrapname	Prevent word wrapping in the output of template name/link (parameters will wrap if needed)	{{example}}
plaincode	Uses <code style="border:none; background:transparent;">...</code>	{{example}}	{{tltss}}
subst	Include a subst: prefix before the template link/name	{{subst:example}}	{{tls}}, {{tlxs}}, etc
alttext=[text]	Replace [text] with the actual label to be displayed for the template link	{{example}}	{{tla}}
_show_result	Will also display the result of the template	{{Min|7|-5}} → -5
_expand	Will add a link to the expanded template page	{{Min|7|-5}} [1]
a	will add an asterisk before the template code	* {{Min|7|-5}}

Unnamed (Positional)

This template can take any number of unnamed parameters as parameters accompanying the template link (or name); see Examples below.

Examples

Use the displayed value in the code column, not the underlying source code.

Note

On the source sister projects, en.wikipedia and Meta, X0, X1, X2, ..., X9 are sandbox templates for experimentation on involved templates that need be in template space. An auto-cleansing software facility exists that might be used to duplicate the facility on other Sister projects.
