Template:Country showdata/doc

Usage
This template is automatically invoked by the standard syntax of a country data template:

The first parameter to a country data template is usually the name of a formatting meta-template. For example, Template:Flag uses Template:Flag/core to actually render the flag icon and wikilink. If the first parameter is missing, which is the case when a country data template is viewed directly, the template code fragment  ensures that this template will be used as the default first parameter. This technique ensures that country data templates are "self-documenting" if they use the standard syntax.

Additional parameters
Many country data templates require additional documentation beyond the standard mandatory  and   parameters. This template will automatically document standard optional parameters (such as ) if present, and can document unique optional parameters (such as flag variants) if instructed to. This latter method uses documentation-specific parameters in the country data template to activate the additional output from this template. These documentation parameters are set off from the rest of the parameters in the country data template by a  section: &lt;noinclude&gt; &lt;/noinclude&gt;
 * var1 = ...
 * redir1 = ...
 * related1 = ...

Flag variants
Flag variants are added to a country data template by the inclusion of one or more  parameters, where each   is a unique identifier that is subsequently used as an input parameter to ,  , etc. To document these flag variants, use the   documentation parameters to identify each label.

For example, Template:Country data Seychelles identifies three flag variants (in addition to the current flag) with the following code: These three variants are documented by the following code segment later in the template: &lt;noinclude&gt; ... &lt;/noinclude&gt; Up to forty flag variants can be documented by this method (using  to  ). If more are present, these can be listed on a separate documentation subpage as described below.
 * flag alias-1976 = Flag of the Seychelles 1976.svg
 * flag alias-1977 = Flag of the Seychelles 1977.svg
 * flag alias-colonial = Government Ensign of the United Kingdom.svg
 * var1 = 1976
 * var2 = 1977
 * var3 = colonial

Note that you do not have to use a  parameter for the standard optional variant labels ,   and   (used for the country's naval, air force and army ensigns, respectively). If present, they will automatically be documented.

Redirect aliases
Many country data templates have alias names that can be used instead of the usual country name with all of the main flag templates. These are usually, but not exclusively, standard country code abbreviations such as those specified in ISO 3166-1 alpha-3 or by the IOC or FIFA. These are implemented as redirects, and are listed in Category:Country data redirects.

For example, Template:Country data DEU and Template:Country data GER both redirect to Template:Country data Germany, because DEU is the ISO code and GER is the IOC and FIFA code for Germany. Therefore,,  , and   all have the same result. These redirect aliases are documented by the following template code fragment: &lt;noinclude&gt; ... ... &lt;/noinclude&gt;
 * redir1 = DEU
 * redir2 = GER

Up to five flag redirects can be documented by this method (using  to  ).

Related templates
Several country data templates are used for alternative forms to the common country data template for the nation, usually but not exclusively for historic nations. Pointers to these alternative templates are useful additions to the template documentation so that editors can use the correct template for their specific purposes.

For example, Template:Country data Serbia and Montenegro includes the following code to document three other related country data templates: &lt;noinclude&gt; ... ... &lt;/noinclude&gt;
 * related1 = Serbia
 * related2 = Montenegro
 * related3 = FR Yugoslavia

Up to six related flags can be documented by this method (using  to  ).

Flag article link
This template shows a large flag image on the right of the documentation box, with a link to an article about the flag in the caption if it exists. The page that it evaluates is "Flag of ", with the value of alias in the template code replacing. If there is an article about the flag even though "Flag of " does not exist, either create the latter as a redirect to the correct page or add the following parameter: &lt;noinclude&gt; ... ... &lt;/noinclude&gt;
 * flag link = Article name

This can also be used to override the automatic link if "Flag of " does exist but leads to the wrong article.

Additional documentation
For situations where the automatic documentation method is not completely adequate, additional documentation can be displayed by. Simply create a documentation subpage (named as ) with the additional material, and it will be transcluded after all other output sections.

For example:
 * Template:Country data Ireland/doc is used to explain why that template is distinct from Template:Country data Republic of Ireland
 * Template:Country data France/doc is used to document the list of country data templates available for each of the regions of France
 * Template:Country data United States/doc is used to document the full set of flag variants (for each number of stars), and to list all of the country data templates available for state and territory flags

Categorization
This template automatically categorizes pages it is transcluded on in Category:All country data templates and in the tracking categories in Category:Country data tracking categories. Content categories, such as those by country or by type/status, should be added manually by putting them inside  tags on a template's documentation subpage. If a template does not have a documentation page yet, click on the "/doc" link at the bottom of the automatic documentation, add categories between the preloaded tags and save the page.

The default sort key used for the automatic categories is the part after  in the page title (overwritten by the deprecated templatename parameter if specified). The parameter cat can be used to specify a custom ASCII sorting key for these categories. For example, Template:Country data Åland Islands and Template:Country data Republic of Ireland use this parameter to sort them under "A" and "I" respectively.
