Shortcut

{{tnull}}

This template uses Lua:

Module:Template link general (sandbox)

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}}.

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.

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}}
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	{{Other}}	{{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]

Unnamed (Positional)

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