Template:Dir2

Note: This template is used on a lot of pages. In order not to put too much load on the servers, edits should be kept to a bare minimum. Please discuss proposed changes on the talk page first. Editing a template causes all pages that use the template to be re-rendered. If the template is used often, this can put a lot of load on the servers since it fills up the job queue. Keep in mind that templates that are used on file description pages also show up on other wikis.

Usage

{{Dir2 |1= |2= |3= }}

Unlike the other version (Template:Dir) implemented using only wiki syntax and the builtin parser function #switch, this template just uses directly a Lua implementation which has several advantages, including (but not only):

• BCP47 conformance for resolution of script variants
• support of legacy language codes (including non BCP47 codes still used by Wikimedia and not fully migrated to BCP47-conforming codes
• higher coverage of languages and script variants
• reduction of the average template expansion cost (below 1ms per invokation, even when including the initial cost for instantiating a Lua VM, which is constant)
• significant reduction of the template expansion cost in MediaWiki (this is useful where you need to use a conditional direction several thousands times on the same page (so the Lua version can be used for example to render fully translatable HTML tables with thousands cells whose text content or formatting depends on the direction of a target language)
