Module:Engvar
![]() | This module depends on the following other modules: |
This module implements {{engvar}}. It allows templates to show national varieties of English, when |engvar=
is passed by each article.
For example, one template can display "football" for |engvar=en-UK
articles, and "soccer" for |engvar=en-US
articles.
Parameter list
Template
{{#invoke:engvar|variants
| defaultWord =
| defaultLang =
| engvar = <!-- Pass-through the editor's choice, set to 'auto' to automatically detect -->
| en-XX = <!-- add country code for XX, and the nation language word -->
| en-YY = <!-- add more varieties as might be needed -->
| engvarCat = <!-- '=no' will suppress message category in article page -->
| fallback = <!-- set to 'true' to allow commonwealth languages to fallback to 'en-GB'. False by default unless engvar='auto'. -->
}}
Article
{{example
| engvar =
| engvarCat =
}}
Maintenance category
Articles with an invalid |engvar=
will be placed in the hidden maintenance category Category:Articles using an unknown Template:Engvar option. Articles listed may need editing.
An article's requested |engvar=
may be unspecified in the template. For example, if an article uses {{example|engvar=South African English}}
but the template has no |en-ZA=
, then the template will return |defaultWord=default color name
. The category will not be used.
- When this categorization is not desired for a whole template, set
|engvarCat=no
in the template - Otherwise pass-through this setting from the article:
|engvarCat={{{engvarCat|yes}}}
. This allows the editor to switch categorization off per article.
Articles are sorted by |engvarCatSort=
or {{pagename}} by default. Note that other templates will fill this category. Set this parameter like |engvarCatSort=Personal prefs
in a template to group its listings under "P".
List of English varieties
In the template, use the exact ISO-code as the parameter name like |en-GB=vapour
. Write |en-US=soccer
not |American English=soccer
. Needed varieties have articles using the template and words differing from the default.
English variety | ISO-code |
---|---|
American English | en-US
|
Australian English | en-AU
|
British English | en-GB
|
Canadian English | en-CA
|
Hiberno-English (Irish-English) | en-EI
|
Hong Kong English | en-HK
|
Indian English | en-IN
|
Jamaican English | en-JM
|
Malawian English | en-MW
|
New Zealand English | en-NZ
|
Nigerian English | en-NG
|
Pakistani English | en-PK
|
Philippine English | en-PH
|
Scottish English | en-SCO
|
Singapore English | en-SG
|
South African English | en-ZA
|
Trinidadian English | en-TT
|
British English Oxford spelling British (Oxford) English Oxford English Dictionary (OED) |
en-OED
|
IUPAC spelling | en-IUPAC
|
There is backwards compatibility for leeway in articles. |engvar=en-US
, |engvar=United States
, |engvar=US
can all show the |en-US=football
variety.

-- This module implements Template:Engvar.
-- Template:Engvar is to be build into the template (like an infobox), with default & variant spellings defined.
-- That template should also allow parameter '|engvar=' for the editor (article page).
-- The module/template Engvar then returns the spelling variant as is set in that article (for example '|engvar=en-GB').
-- The defaultWord is returned, unless the engvar input hits on a defined (en-XX) variant word.
