Not the lauguage you want? The default tartget lauguage is zh-CN(Chinese Simplified). You can edit it in the Preference menu.


  • Translate Engine
    The default engine is Google Translate. Currently we provide Youdao as optional engine.
    如果你无法访问谷歌,请选择有道作为翻译引擎。Youdao doesn’t support some lauguages.

  • Lauguage Parameter
    Edit here to change translation target language.
    Find your Language Culture Code in this link:
    Language Culture Code
    Take ja-JP as example:
    For Google Translate users, the Lauguage Parameter is sl=en&tl=ja-JP. Here sl is source language and tl is target language.
    For youdao(有道) users, the Lauguage Parameter is EN2JA-JP. It means from EN(English) to JA_JP(Japnese).

Lauguage Parameter Setting


Invoke make with the VERSION variable set in the environment. For example:

VERSION=0.0.1 make

Alternatively, version numbers can be passed to make directly:

make VERSION=0.0.1
