Template:Template link with subst

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

This template is used in system messages.
Changes to it can cause immediate changes to the Wikipedia user interface.
To avoid major disruption, any changes should be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can be added to this page in a single edit. Please discuss changes on the talk page before implementing them.

{{tls}}
{{tlsp}}

This template uses Lua:

Module:Template link general (sandbox)

This template, often abbreviated as {{tls}}, 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[edit source]

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>` 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>` 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 `< 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)[edit source]

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

Examples[edit source]

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.

`{{=}}` is okay (see Template:=)	{{subst:x1\|x=u}}	Sticky nowiki is okay.
{{tls\|x2\|3=two\|2=one}}	{{subst:x2\|one\|two}}	Right-to-left is okay
{{tls}}	tls	With no arguments, it emits the current page name without braces.
{{tls\|x2\|3=one\|4=two}}	{{subst:x2}}	Null parameter stops parsing.

Wrapping of long names (default)
Code	Output
{{tls\|long template name that would wrap to new line\|this is a long value for the 1st parameter that would wrap}}	{{subst: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
{{tls\|nowrap=on\|long template name that would wrap to new line\|long value for the 1st parameter that would wrap}}	{{subst: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
{{tls\|nowrapname=on\|long template name that would wrap to new line\|long value for the 1st parameter that would wrap}}	{{subst:long template name that would wrap to new line\|long value for the 1st parameter that would wrap}}
