问题:

There used to be a few services that used Google Translate API V1 to automatically translate .po files.

Google has stopped their V1 API and with V2 they charge $20 for 1.000.000 words.

I have searched but cannot find any tool that offers translation with the V2 version. You would expect someone to update their tool and charge $2 for 20.000 words and make a good profit.

Are there any paid or free tools that will automatically translate .po files?

回答1:

little bit late but google now provides this functionality

回答2:

See my free PHP tools Potrans, which translate PO files using Google Translator API

Download from repo here: https://github.com/OzzyCzech/potrans

Feel free to edit this post to make corrections or better error handling. I'm not an expert on the .po file format, but I think this will work with my angular-gettext needs. I think the only external library I used was Newtonsoft's Json.NET. I am not affiliated with Frengly. It came up on google. I'd recommend using a different translation API if you need more than 1 translation per 3 seconds.

Input File: template.pot

msgid ""
msgstr ""
"Content-Type: text/plain; charset=UTF-8\n"
"Content-Transfer-Encoding: 8bit\n"

#: Comment
msgid "You do not have permission to view this application"
msgstr ""

msgid "You have permission to view this application"
msgstr ""

Input Command: > program.exe template.pot en es_VE fr_FR

Output File 1: en.cache.json This is created so that whatever translation utility you're using doesn't have to be hit over and over again.

{
  "es_VE": {
    "You do not have permission to view this application": "Tu no la habana permiso que vista este aplicación",
    "You have permission to view this application": "Tu tienes permiso que vista este aplicación"
  },
  "fr_FR": {
    "You do not have permission to view this application": "Vous le faites pas as autorisation a vue cette une demande",
    "You have permission to view this application": "Tuas autorisation a vue cette une demande"
  }
}

Output File 2: es_VE.po
