New page

== Analysis of the code ==

=== The code ===
<nowiki>{{#ifexist:
{{#if: {{{2|}}}
| {{{2}}}
| {{#if: {{NAMESPACE}} | {{NAMESPACE}}:}} {{BASEPAGENAME}} }}/{{{1}}}
| &nbsp;&bull;&nbsp;
{{#if: {{{2|}}}
| {{#if:{{{3|}}}
| {{#ifexist:
{{{1}}}:{{{3}}}
| [[ {{{1}}}:{{{3}}} | {{#language:{{{1}}} }} ]]
| [[ {{{2}}}/{{{1}}} | {{#language:{{{1}}} }} ]]
}}
| [[ {{{2}}}/{{{1}}} | {{#language:{{{1}}} }} ]]
}}
| [[ :{{NAMESPACE}}:{{BASEPAGENAME}}/{{{1}}} | {{#language:{{{1}}} }} ]]
}} 
| 
}}</nowiki>

=== Interpretation ===
IF the following page exists:
IF there is a 2nd parameter
THEN
<nowiki>{{{2}}}</nowiki>
ELSE
IF <nowiki>{{NAMESPACE}}</nowiki> is not the Main space
THEN <nowiki>{{NAMESPACE}}</nowiki>:
<nowiki>{{BASEPAGENAME}}</nowiki>
THEN
Produce &nbsp;&bull;&nbsp; and a span: <code><nowiki></nowiki></code>
IF there is a 2nd parameter
THEN
IF there is a 3rd parameter
THEN
IF the page exists: <nowiki>{{{1}}}:{{{3}}}</nowiki>
THEN <nowiki>[[ {{{1}}}:{{{3}}} | {{#language:{{{1}}} }} ]]</nowiki>
ELSE <nowiki>[[ {{{2}}}/{{{1}}} | {{#language:{{{1}}} }} ]]</nowiki>
ELSE
<nowiki>[[ {{{2}}}/{{{1}}} | {{#language:{{{1}}} }} ]]</nowiki>
ELSE
<nowiki>[[ :{{NAMESPACE}}:{{BASEPAGENAME}}/{{{1}}} | {{#language:{{{1}}} }} ]]</nowiki>
Close span: <nowiki></nowiki>
ELSE
Produce an empty span: <nowiki></nowiki>

=== What it does ===
Parameters:
# The country code (CC)
# (optional) An alternative page name (AN)
# (optional) A translated alternative page name (TAN)

Checks if a country-specific page exists
* By default (NAMESPACE:)BASENAME/CC, so based on the page where the template is called.
: Example: My great page/nl
: Example: User:Me/My great page/fr
* If AN is given, then test for the existence of a page called AN

If a country-specific page exists, then construct an entry for the table that is built by Template:Languages
* start with <nowiki> • </nowiki>
* Open a span, with an anchor 'lang': 
* Create a link to the country-specific page
** By default <code><nowiki>[[ :{{NAMESPACE}}:{{BASEPAGENAME}}/CC | {{#language:CC }} ]]</nowiki></code>
*: Example: <code><nowiki>[[::My great page/nl | Nederlands ]]</nowiki></code>
*: Example: <code><nowiki>[[:User:Me/My great page/fr| Français ]]</nowiki></code>
** If an AN but no TAN was given,
*: then <code><nowiki>[[AN/CC | {{#language:CC }} ]]</nowiki></code>
*: Example: <code><nowiki>[[Alternative name/nl | Nederlands ]]</nowiki></code>
*: Example: <code><nowiki>[[Alternative name/fr | Français ]]</nowiki></code>
** - If an AN and a TAN was given,
*** - and page CC:TAN exists,
**: then <code><nowiki>[[CC:TAN | {{#language:CC }} ]]</nowiki></code>
**: Example: <code><nowiki>[[nl:Alternatieve naam | Nederlands ]]</nowiki></code>
**: Example: <code><nowiki>[[fr:Nom alternative | Français ]]</nowiki></code>
*** - but page CC:TAN does not exist,
**: then fall back to <code><nowiki>[[AN/CC | {{#language:CC }} ]]</nowiki></code>
* Close the span: 

If the page given by the parameters does not exist, then issue an empty span:
<nowiki></nowiki>

Note: <code><nowiki>{{#language:CC}}</nowiki></code> Converts the country code into the name for that CC's language, written in that language. So 'en' becomes 'English', 'nl' becomes 'Nederlands', 'fr' becomes 'Français', etcetera.
