[edit] Documentation
{{Tlrow|template|up to 3 parameters}} is used in template lists, it creates a row (or begin of a row) for the specified template.
Parameter category= (empty string) is automatically set in the demo template call, it's conventionally used to suppress the addition of template lists to categories managed by the template in question.
[edit] Example
| Code | Result | ||||||
| {| border="1" cellpadding="3" !''input''!!''output'' {{Tlrow|evd|0expr|2+3}} {{Tlrow|tlx|0expr|2+3}} |} |
|
The template isn't designed to support empty or named parameters. For such cases build the row manually, the 2nd coloumn is the actual template call, for the first column use {{tetl|template|up to 3 parameters}}.
[edit] Background
- {{Tlrow}} is for the common simple cases in template lists, a left column with the syntax and internal links (talk, links, view), a right column with the example output as shown above. For these cases {{Tlrow|T|x|y|z}} is merely a shorthand for
- |-
- |{{tetl|T|x|y|z}}
- |{{T|x|y|z}}
- You can add more info below, continuing the right = result column. {{tetl}} is also a shorthand, it has the same effect as
- {{tlx|T|x|y|z}}<br />{{lts/|T}}
{{tlrow}} skips the {{tetl}} step using {{Tlx}} and {{Lts/}} directly for some extra magic explained below. Likewise {{tetl}} skips {{tlx}} and {{Lts/}} for historical reasons, it belonged to a set of similar templates now all unified into {{tetl}} and {{tlsetl}}, the latter for templates requiring subst:.
At the core of this zoo were {{tlx}} and {{tlsp}} unifying similar templates, the latter again for templates requiring subst:.
[edit] Category magic
One obstacle with template lists are templates adding all pages where they are used to one or more categories. This can result in a huge number of bogus categories for template lists, corresponding to bogus entries of the list in the various categories.
- A simple convention in the listed templates can avoid this, instead of
- [[Category:somecat ]]
- use
- {{{category|[[Category:somecat ]]}}}
If the dummy parameter category is undefined the category works as before because it is the parameter default. If the parameter is defined and empty adding |category= to the template call bypasses the default, its output is an empty string.
{{Tlrow}} adopted this convention and adds |category= automatically in examples. If a template has its own ideas about parameter category you cannot use {{tlrow}}, just use the slightly more verbose {{tetl}} variant. If a template doesn't support this trick the unused named parameter causes no harm. See also WP:CT with many examples.
Some template lists add links to the categories populated by the listed templates. {{tlrow}} supports this with an optional parameter category=name. Because it uses this parameter anyway internally for the convention explained above it can use it for a different purpose in the left column, adding a category link [[Category:name|category]] in front of the other links (talk, links, view).
For consistent output on existing template lists it adds an additional empty line in this case, arguably that "feature" could be removed.
- Please note that {{tetl}} doesn't support this magic to keep it simple and in line with {{tlsetl}}. If you can't use {{tlrow}}, e.g. for templates with named parameters, and want the output to be consistent, go directly to
- |-
- |{{tlx|T|x|y|z}}<br />{{lts/|T}}
- |{{T|x|y|z}}
- and add the category link in front of {{Lts/|T}}.
[edit] Subpages
Some template lists have to list pages outside of the template namespace, typically user or project subpages. {{tlrow}} and all other templates mentioned above don't support this at the moment. Use where you'd write {{Tlx}} in the case of templates, its output is similar for up to three parameters.
| Scope | without subst: | with subst: |
|---|---|---|
| template, no parameter | ||
| template, up to 3 parameters | ||
| any page up to 3 parameters | ||
| template list up to 3 parameters |

[edit] Problems with images from commons.wikimedia and userspace userboxes
This template won't pull images from common.wikimedia.org -- for instance: Template:User Roman Catholic
| {{User Roman Catholic}} |
Template:User Roman Catholic |

- I believe this is actually a problem with the Tlx template. Banaticus 06:12, 6 October 2006 (UTC)
[edit] User Namespace template problem
How about adding a parameter that tells the template which namespace to use? For instance, I adopted a User Box. That user box was listed on a page with {{Tlrow}}. I updated the line listing the user box -- only to find that Tlrow doesn't work with templates in the User namespace. The new template would default such that the existing behaviour would be the default. Will (Talk - contribs) 04:48, 1 December 2006 (UTC)
[edit] Adding-current-page-to-category problem
Wikipedia:Userboxes/WikiProjects, etc., adds themselves to every category for which a category-adding userbox is listed, as a result of this template. Isn't there some way to short-circuit that? I don't know enough about the "esoterics" of WP templating to be sure. It kinda lame to have Wikipedia:Userboxes/WikiProjects show up in [[Category:WikiProject Foo members]]. — SMcCandlish [talk] [contrib] ツ 06:29, 12 December 2006 (UTC)
[edit] Problems with default values for parameters ({{inappropriate person}})
It seems this template has a problem with the {{inappropriate person}} template as displayed in Template messages/Cleanup. It blanks out the default parameter value. --MooNFisH 10:55, 30 June 2007 (UTC)
