Translate in normal mode

$ dptran Hello
こんにちは
$ dptran -t FR Hello
Bonjour

It is possible to specify the source language with the -f option and the destination language with the -t option. If you omit the destination language option, the translation will be done in Japanese.

For more information about language codes, see the language list:

$ dptran list -s    # for the list of source languages
$ dptran list -t    # for the list of target languages

Translate in interactive mode

$ dptran
> Hello
こんにちは
> Ich stehe jeden Tag um 7 Uhr auf.
毎日7時に起きています。
> Seriously, Hiro, you need to improve your English.
マジでヒロさん、英語力アップしてください。
> 今天玩儿得真开心！
今日は素晴らしい時間を過ごせました
> quit

Multiple source texts can be translated interactively.
Exit with quit.

If you want to translate the source texts into a specific language, use the -t option.

Translate multiple lines

To enter multiple lines, use the -m option.
Then enter a blank line to send the input.
