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 fr" xml:lang="fr"> 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 >>> 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. >>>> — [[NicolasLimare]] >>>>> 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]] >>>>>> My mistake, I meant $config{locale} --[[NicolasLimare]] > So the patch below could be changed to parse `$config{locale}` for the > language, and pass it if no specific lang was set for the page. The only > problem with that would be that this is all done inside the meta plugin, > so if that plugin were disabled, the lang would be empty. To avoid that, > I guess that the template needs to look like: lang="" xml:lang=""> > Now it just needs to be finished up.. --[[Joey]]
