Extension:TemplateData/zh

TemplateData扩展引入了标记和API，它们共同允许编辑者指定应如何调用模板. 此信息作为最终用户的格式良好的表提供，并作为JSON API提供，它使其他系统（例如VisualEditor）能够构建用于处理模板及其参数的接口. 有关深入的帮助，请参阅.

编辑数据
TemplateData扩展通过在模板页面的wikitext中定义标记来工作（可选地，它也可以从不同的页面中转换）. This is designed to be compatible with the common layout many wikis have of transcluding template documentation from a separate page (but is not required). This content of the tag must be valid JSON using the format described below; note that all descriptions must be in plain text (no wikitext is accepted inside the template data).

When a block is included on a page, the TemplateData extension performs the following checks when the page is being saved:


 * 1) The contents must be valid JSON;
 * 2) Each item within the JSON structure must be of the expected type as specified below (e.g. object, array, or a primitive); and
 * 3) For those items which have a specified list of possible values (e.g.  ), the value in the JSON object must match one of those values.

If any of these checks fails, the server will not be permitted saving and an error message will be displayed above the edit page.

For autovalue items, bug 2700 prevents  from working in any template that is added inside a, including  and  tags. The TemplateData block will save correctly, but the resulting wikitext will not be parsed correctly when the template is used.

Note that  you cannot use  in lieu of.

Format
The below is a visualised version of the JSON data as defined on the template page enclosed by   tags. The formal specification is available in the TemplateData repository. Refer to Specification.md for the latest version.

TemplateData object
The TemplateData object is a JSON root element enclosed in a  element on the template page.

InterfaceText (string or object)
A free-form plain-text string (i.e. no wikitext or HTML) in the content-language of the wiki, or an object containing those strings keyed by language code.

The default value for all InterfaceText fields is.

String type
If it is a string, it must contain a non-localized string in the content language of the local wiki.

Object type
If it is an object, the object must have this mapping:

示例
An example TemplateData structure as specified within wikitext on a template page. Below is how the above example would be displayed on the template page: {   "description": "Label unsigned comments in a conversation.", "params": { "user": { "label": "User's name", "type": "wiki-user-name", "required": true, "description": "User name of person who forgot to sign their comment.", "aliases": ["1"] },       "date": { "label": "Date", "suggested": true, "description": { "en": "Timestamp of when the comment was posted, in YYYY-MM-DD format." },           "aliases": ["2"], "autovalue": "" },       "year": { "label": "Year", "type": "number" },       "month": { "label": "Month", "inherits": "year" },       "day": { "label": "Day", "inherits": "year" },       "comment": { "required": false }   },    "sets": [ {           "label": "Date", "params": ["year", "month", "day"] }   ],    "maps": { "ExampleConsumer": { "foo": "user", "bar": ["year", "month", "day"], "quux": [ "date", ["day", "month"], ["month", "year"], "year" ]       }    } }

API
See the generated help at Special:ApiHelp/templatedata. A sample invocation (formatted for human readability) is:

This returns the template data for Template:Cite web. The ... block for this template is on its transcluded template documentation page, en:Template:Cite web/doc.

Additions and changes to JSON as received from the API
The JSON structure provided in response to an API HTTP get request is significantly different than that which is defined in the ... block. In response to the API request, extension TemplateData makes the following changes to the JSON object:
 * Adds two wrapping objects:
 * An overall Pages Object containing one or more Page Objects
 * An object with a numeric key: a Page Object
 * Additions/changes to the actual TemplateData Object
 * Add the  key with the name of the page from which the data was requested (e.g. "Template:Cite web").
 * Add the  key and array using the order in which the parameters occur in the   key within the TemplateData Object on the template page.
 * Add the  key
 * Change all TemplateText occurrences that are just strings to objects with a single key for the current wiki's Wikipedia language code
 * Remove all  keys.
 * Add all properties from parameter from which an inheritance is defined which are not superseded by explicitly defined keys in the inheritor's Parameter Object.
 * Add default values for all keys in each Parameter Object which have not been explicitly defined or inherited.
