Template:Template link code/doc

Template:High risk

Purpose and naming

When a template name with braces {{ }} is to be shown in documentation, the braces have to be escaped in some way so it doesn't become an actual call to the template. Instead of using <nowiki></nowiki> tags you can write it more simply and concisely by using the {{tlc}} template.

This template works similarly to {{tl}} and {{tlx}}, but doesn't make the template name into a link (template link cleared). When writing documentation you might want to avoid a lot of unnecessary links, since they can decrease readability. So on the first occurrence of a template name use {{tl}} or {{tlx}}, and then use {{tlc}} thereafter.

The name was based on {{tl}} template link, despite the fact that, unlike the actual {{tl}} template, these templates don't include an actual link.

Basic operation

The template looks like this (code is to the left; actual rendering to the right): {{tlc|name|parameters}}{{name|parameters}}

Documentation

Functional details

  • This template takes another template-name and some associated pipe-tricked (numbered) parameters (or 'pass parameters'), and displays them as an 'example demonstration' of how the template-name template could be coded, literally. Its primary use is in instruction and documentation.
  • It shows a template name and up to eight parameters, including empty parameters.
  • It prevents line wraps in its output.

Usage

{{Tlc|Template|first_parameter|second|third|...|eighth}}{{Template|first_parameter|second|third|fourth|fifth|sixth|seventh|eighth}}

Examples

Code Result Comment
{{tlc}} Lua error in Module:Template_link_general at line 119: attempt to concatenate local 'titlePart' (a nil value). Shows its own syntax.
{{tlc|name}} {{name}}
{{tlc|name|one}} {{name|one}}
{{tlc|name|one|two}} {{name|one|two}}
{{tlc|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.
{{tlc|name|||three|four}} {{name|||three|four}} Also shows empty parameters.
{{tlc|name|||three}} {{name|||three}} Even shows empty parameters that come in the end.
{{tlc|name|one=a|two=b}} {{name}} The use of equal signs is a problem, but there is a fix; see next row.
{{tlc|name|oneTemplate:((=Template:))a|twoTemplate:((=Template:))b}} {{name|one=a|two=b}} Use {{=}} in place of an equal sign, so that it gets rendered properly.
{{tlc|name|Template:Tlf|two}} {{tlc|name|Template:IPA|two}} Nested template calls also cause problems ...
{{tlc|name|{{tlf|IPA|/tʃ/}}|two}} {{tlc|name|Template:Tlf|two}} ... but there are ways to get around this issue, also.
{{tlc|name|{{((}}IPA{{!}}/tʃ/{{))}}|two}} {{tlc|name|Template:Tlf|two}} ... another way to do the same thing, using {{((}}, {{!}} and {{))}} to insert literal {{, | and }}, respectively.

An alternative to using constructs such as {{=}} and {{tlf|...}} to prevent characters from getting interpreted syntactically is to use <code><nowiki>...</nowiki></code>, which will prevent all characters from being interpreted. For example, in place of

{{tlc|name|one{{=}}{{tlf|IPA|/tʃ/}}|two}}

you can use

<code><nowiki>{{name|one={{IPA|/tʃ/}}|two}}</nowiki></code>

Both render as

{{name|one={{IPA|/tʃ/}}|two}}

If a vertical display with parameters on their own lines is desired, this can also be laid out manually in this manner, or more rapidly done with <pre>...</pre>.

Here is the code to emulate {{tlc}} using <nowiki>:

Using templates: Using <nowiki>: Rendered result:
{{tlc|name|one{{=}}a|two{{=}}b}} <code><nowiki>{{name|one=a|two=b}}</nowiki></code> {{name|one=a|two=b}}

Limitations

As documented at Help:Template, template arguments starting with one of the four MediaWiki magic characters : ; * or # are interpreted as if they were at the beginning of a line, and are formatted as HTML lists. To avoid this, references to {{*}} or {{#expr}} must have the first character escaped. You can either use <nowiki /> or an escape like &#35;.
