Module documentation--[=[
This module is a rewrite of the existing wikitext template {{Language with name/for}}. The primary purpose of
the rewrite is to bring the non-English text into the template so that it can be marked up by {{lang}}.
To accomodate the variety of uses of the template, news parameters are introduced to allow variable styling.
supported parameters (original)
{{{1}}} – language tag
{{{2}}} – non-English 'term' to be wrapped in {{lang}} using tag in {{{1}}}; modified to accept keyword 'none' to prevent categorization
{{{3}}} – English translation of {{{2}}} in single quotes; alias: |term1=
|links= – 'yes' or 'no'; default is 'yes'; links language name derived from {{{2}}}
supported parameters (new)
|term1= – alias of {{{3}}}
|term2= .. |termn= – additional 'or'-like translations; each rendered in single quotes; quoted terms separated by '<space>/<space>'
|italic-term= 'yes' or 'no'; default is 'no'; useful to multi-term translations when all should be italicized
|lang-name= – for those cases where ISO 639 does not have a language tag; {{{1}}} ignored; template wraps {{{2}}} with {{lang}} using 'mis' (uncoded language)
|break= – 'yes' or 'no'; default is 'no'; inserts <br /> between {{{2}}} and the rest of the rendering
|paren= – takes one of three values:
'none' – omit left and right parens around '<language-name> for <term>'
'left' – includes left paren, omits right paren
'right' – includes right paren, omits left paren
because this template now calls {{lang}} properly, it also supports the {{lang}} parameters:
|rtl=
|italic= (and aliases |italics= and |i=)
|size=
|cat=
|nocat=
basic rendering
<non-English text> (<language-name> for '<term>')
multiple terms
<non-English text> (<language-name> for '<term>' / '<term>' / '<term>')
|paren=none
<non-English text> <language-name> for '<term>'
|break=yes
<non-English text><br />(<language-name> for '<term>')
|italic-term=yes
<non-English text> (<language-name> for '<i><term></i>' / '<i><term></i>' / '<i><term></i>')
|lang-name=<lang-name>
<non-English text> ([[<lang-name> language|<lang-name>]] for '<term>')
