languages.conf

A language exists because messages/ holds a file for it. This file only names it, so a window and a message can show Türkçe rather than tr, and gives it an icon. Read at start and on every reload.

names

names {
  en = "English"
  tr = "Türkçe"
  de = "Deutsch"
  es = "Español"
  fr = "Français"
  pt = "Português"
  ru = "Русский"
}

icons

icons {
  default = "PAPER"
  en = "basehead:eyJ0ZXh0dXJlcyI6..."
}

An icon is a material such as PAPER, or a head written as basehead:<value>, the long Value a head site lists under "For Developers". A language with no icon takes default. The shipped flags are the country each file is written for:
