This module will transliterate Greek language text per WT:EL TR. It is also used to transliterate Cappadocian Greek, Calabrian Greek, Italiot Greek, Pontic Greek, and Tsakonian. The module should preferably not be called directly from templates or other modules. To use it from a template, use {{xlit}}. Within a module, use Module:languages#Language:transliterate.

For testcases, see Module:el-translit/testcases.

Functions

tr(text, lang, sc)

Transliterates a given piece of text written in the script specified by the code sc, and language specified by the code lang.

When the transliteration fails, returns nil.
