This module depends on the following other modules: |
This Lua module is used on many pages and changes may be widely noticed. Test changes in the module's /sandbox or /testcases subpages, or in your own module sandbox. Consider discussing changes on the talk page before implementing them. |
This pulls data from data modules and bunches them together. Language names are gathered in this order:
- Module:Language/data/ISO 639-3 – as defined in ISO 639-3
- Module:Language/data/iana languages – as defined by the IETF-sanctioned IANA registry; names almost always the same as ISO, but does not include 3-letter codes for languages with 2-letter codes, hence the fallback
- Module:Language/data/wp languages – specific to Wikipedia; languages for which we've decided another name is better
In other words, a name set in wp languages will take precedence over one set in iana languages and that too would take precedence over one from iso 639-3. wp languages can be discarded by passing dataset="iana"
to the parent module.
