doc/todo/language_definition_for_the_meta_plugin.mdwn



Here is a patch for the [[plugins/meta]] plugin. It adds the possibility to define the language
used for a page, with [[meta lang="ja"]]
It doesn't insert the langage information in the xhtml meta elements, but defines a LANG
variable to use in the templates, for example with
<html xmlns="http://www.w3.org/1999/xhtml"
      lang="<TMPL_IF NAME="LANG"><TMPL_VAR LANG><TMPL_ELSE>fr</TMPL_IF>"
      xml:lang="<TMPL_IF NAME="LANG"><TMPL_VAR LANG><TMPL_ELSE>fr</TMPL_IF>">

This way also allows to define a language for a subset of the final page, with custom
templates and inclusion.
This may be useful for sites with a few pages in different languages, but no full i18n.

Looks good, but the need to modify the template and include a default
language in it is a bit problimatic, I think. --[[Joey]]


--lang=XX could be a setup option, with a default value, then the template would be


            <html xmlns="http://www.w3.org/1999/xhtml" lang="<TMPL_VAR LANG>" xml:lang="<TMPL_VAR LANG>">


Yes, that seems reasonable. I guess there's no problem with defaulting
to en if it can be overridden in the setup. --[[Joey]]


Yes, english default makes sense. I guess we should use the $config{lang},
defined from the setup file or command-line options to define the default language
($config{lang} defaults to en which is fine) if the html pages, and override
it from the meta directive.

ikiwiki already has a $config{locale}, which is a full locale (ie,
"en_US.UTF-8". This just needs to be parsed for the lang. --[[Joey]]
