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

This template is used on approximately 5,200 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them.

Shortcut

{{tnull}}

This template uses Lua:

Module:Template link general

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.

Examples

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.

Code	Output	Remarks
{{tnull\|Banner}}	`{{Banner}}`	Template:Banner does not exist. (Non-existent template is redlinked.)
{{tnull\|Abc}}	`{{Abc}}`	Template:Abc exists.
{{tnull\|abC}}	`{{abC}}`	Template names are case-sensitive
{{tnull\|abc}}	`{{abc}}`	(but the first letter is case-insensitive).
{{tnull\|x0}}	`{{x0}}`	no parameters
{{tnull\|x1\|one}}	`{{x1\|one}}`	one parameter
{{tnull\|x2\|one\|two}}	`{{x2\|one\|two}}`	two parameters
{{tnull\|x3\|1\|2\|3\|4\|5\|6\|7\|8\|9\|10}}	`{{x3\|1\|2\|3\|4\|5\|6\|7\|8\|9\|10}}`	ten parameters
`{{convert\|14\|m\|ftin\|abbr=out\|sp=us}}`	Unlimited parameters, as one `<nowiki>...</nowiki>` string.	{{tnull\|x2\|\|two\|\|}}
`{{x2\|two}}`	Empty parameters are discarded.	{{tnull\|x0\|code=on}}
`{{x0}}`	<code> style	{{tnull\|x0\|plaincode=on}}
`{{x0}}`	plaincode style	{{tnull\|x0\|kbd=on}}
`{{x0}}`	<kbd> style	{{tnull\|x0\|bold=on}}
`{{x0}}`	bold link/name	{{tnull\|x1\|one\|italic=on}}

`{{x0}}`		{{tnull\|x0\|brace=on}}
`x0`	all braces in link	{{tnull\|x0\|braceinside=on}}
`x0`	inside braces in link	{{tnull\|x0\|alttext=x0 link}}
`{{x0}}`		{{tnull\|x0\|bold=on\|code=on\|brace=on}}
`x0`	Combine multiple parameter settings.	`{{abc\| one }}`
Using {{spaces}} before and after a parameter.	{{tnull\|x2\|bold=on\|code=on\|one\|two}}	`{{x2\|one\|two}}`
Can combine named and anonymous parameters ...	{{tnull\|x2\|one\|two\|bold=on\|code=on}}	`{{x2\|one\|two}}`
... in any order ...	{{tnull\|x2\|one\|code=on\|two\|bold=on\|three}}	`{{x2\|one\|two\|three}}`
... even intermixed ...	{{tnull\|x2\|one\|code=on\|two\|bold=on\|three\|italic=on}}	`{{x2\|one\|two\|three}}`
... with many configurations.	`{{x1}}`	= won't work
`{{x1\|x=u}}`	`=` is okay	`{{x1\|x=u}}`
`{{=}}` is okay (see Template:=)	`{{x1\|x=u}}`	Sticky nowiki is okay.
{{tnull\|x2\|3=two\|2=one}}	`{{x2\|one\|two}}`	Right-to-left is okay
{{tnull}}	tnull	With no arguments, it emits the current page name without braces.
{{tnull\|x2\|3=one\|4=two}}	`{{x2}}`	Null parameter stops parsing.

Wrapping of long names (default)
Code	Output
{{tnull\|long template name that would wrap to new line\|this is a long value for the 1st parameter that would wrap}}	`{{long template name that would wrap to new line\|this is a long value for the 1st parameter that would wrap}}`

Wrapping of long names (`nowrap=on`)
Code	Output
{{tnull\|nowrap=on\|long template name that would wrap to new line\|long value for the 1st parameter that would wrap}}	`{{long template name that would wrap to new line\|long value for the 1st parameter that would wrap}}`

Wrapping of long names (`nowrapname=on`)
Code	Output
{{tnull\|nowrapname=on\|long template name that would wrap to new line\|long value for the 1st parameter that would wrap}}	`{{long template name that would wrap to new line\|long value for the 1st parameter that would wrap}}`
