Tɛmplet:Age/doc

This is a documentation subpage for Tɛmplet:Age.
It contains usage information, categories and other content that is not part of the original tɛmplet page.

This template is used on approximately 37,000 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.

This template uses Lua:

Usage[mali mi di yibu sheena n-niŋ]

This template returns the number of full years between two specified dates. If the second set of parameters is not included, it returns the number of full years between a specified date and today's date.

Dates are checked for validity. For example, 29 February 2000 is accepted, but 29 February 1900, 1800 or 2100 are not valid dates.

{{age|1892|1|31|1900|2|29}} → Error: Second date should be year, month, day

{{age|1789|5|1|1800|2|29}} → Error: Second date should be year, month, day

Partial dates such as July 1989 (no day) or 1989 (no month and no day) can be entered using 0 for missing values. Having no year, or having a day with no month is an error.

Please remember to avoid phrasings such as "17 years ago" or "Jones is 65 years old", even when they use this template. See MOS:RELTIME for more information.

For the Supercentenarians, use {{age in years and days}} template.

Syntax: {{age|year|month|day|year2|month2|day2}} or; {{age|year|month|day}} or; {{age|date|date2}} or; {{age|date}}

Examples: {{age|1989|7|23|2003|7|14}} → 13; {{age|1989|7|0|2003|7|14}} → 14; {{age|1989|0|0|2003|7|14}} → 14; {{age|1989|7|23}} → 34; {{age|23 July 1989|14 July 2003}} → 13; {{age|July 1989|2003}} → 14

When entering dates before the Common Era, use astronomical year numbering: 1 BCE is represented by 0, 2 BCE by -1, 3 BCE by -2 etc. For example, the following gives the number of full years since the battle of Cannae, which took place on August 2, 216 BCE:

{{age|-215|8|2}} → 2238

{{age|August 2, 216 BCE}} → 2238

The options described at Module:Age can be used, for example:

{{age|format=commas|-215|8|2}} → 2,238

{{age|format=cardinal|1970|1|1|1998|2|1}} → twenty-eight

{{age|format=ordinal|1970|1|1|1998|2|1}} → twenty-eighth

When only one date is entered, the current date is used for the other date. The template outputs a span that can be used by a calling infobox to detect if only one date was used. The following shows two examples with the exact wikitext that is produced, as seen at Special:ExpandTemplates:

{{age|2010}} → <span class="currentage"></span>14

{{age|format=raw|2010}} → 14

What is template data?[mali mi di yibu sheena n-niŋ]

Template data is the standardized description of a template, used by the default VisualEditor, the optional 2017 wikitext editor and other tools to improve the template-editing experience for the user. Both VisualEditor and the 2017 wikitext editor include a wizard to edit templates, but for the wizard to be most useful, it needs to present specific information to the user about each template, such as a short description of the template's purpose and its parameters. This information is codified formally (by any wiki editor) using template data.

Editing without template data[mali mi di yibu sheena n-niŋ]

Without template data, each parameter needs to be added manually when inserting a new template.

No information is provided about what the value of the parameter should be.

Editing with template data[mali mi di yibu sheena n-niŋ]

With template data, a list of supported parameters (and their description) is provided for the template.

Template data provides context for each parameter, and makes it much easier for users to modify templates.

Adding template data[mali mi di yibu sheena n-niŋ]

Anyone can help by adding template data to templates (particularly high-profile ones, such as infoboxes) so that they are easier to edit in VisualEditor. The following is a minimal example, placed on a template's documentation page:

<templatedata>{
  "description": "insert description here",
  "params": {
    "first parameter": {
      "label": "x",
      "description": "x",
      "type": "string",
      "suggested": true,
      "autovalue": "derived automatic value",
      "default": "default value",
      "required": false
    }
  }
}</templatedata>

You can also add or edit template data using a GUI, by pressing the following button which appears at the top of the edit page: Edit template data

The template data tutorial explains in detail how to add template data information to a template.

Adding suggested values for parameters[mali mi di yibu sheena n-niŋ]

The parameter property suggestedvalues lets you define a list of parameter values to be shown to VisualEditor users in a dropdown for easy selection. This can be done either directly in JSON or using the TemplateData editor with no coding required. Both methods are explained in detail below.

Once the values have been added to template data, the VisualEditor will display them in a combo box (a dropdown into which users can also enter a custom value). The user selects the desired value by clicking on it. If the list of values is long - for example, a list of a country’s states - the user can begin typing in the field, whereupon the list will be filtered to show only values containing the typed text. To change an entered value, the user must simply clear the field, and the full dropdown list will appear again. If the user needs a value not included in the list (for example, "message in a bottle") they can type it in manually.

For suggested values to be displayed in the VisualEditor, the parameter’s type must be set to one of the following options:

content
line
string
number
unknown
unbalanced wikitext.

Other types (file, page, template, user, date, boolean, URL) are not currently supported because they have special functionalities in the VisualEditor already (such as autocomplete) which would interfere with the dropdown menu for suggested values in the VisualEditor.

Adding suggested values for parameters in wikitext[mali mi di yibu sheena n-niŋ]

To add suggested values to any parameter type, add the new property “suggestedvalues” to the parameter in JSON. The “suggestedvalues” attribute must be a list of strings.

An example might look like this:

"media_type": {
	"label": "Type of media",
	"example": "Newspaper",
	"type": "string",
	"description": "In what medium was the article published?",
	"suggestedvalues": [
    	"Journal",
    	"Book",
    	"Newspaper",
    	"Magazine"
	]
}

Adding suggested values for parameters with the template data editor[mali mi di yibu sheena n-niŋ]

For the parameter types listed above, you can add suggested values using the template data editor.

Step 1. Click on "Manage TemplateData".
Step 2. Click on the name of the parameter you want to add suggested values to.
Step 3. If it’s not already, set the type of the parameter to one of the following: content, line, string, number, unknown or unbalanced wikitext. A new input field "Suggested values" will appear. If the parameter is already set to one of these types, the input field should already be visible.
Step 4. Type in the suggested value(s), including any spaces and special characters, and press enter to add it to the list.

Here you can see an example of how to add suggested values in the TemplateData editor.
