go-i18n

go-i18n is a Go package and a command that helps you translate Go programs into multiple languages.

• Supports pluralized strings for all 200+ languages in the Unicode Common Locale Data Repository (CLDR).
  • Code and tests are automatically generated from CLDR data
• Supports strings with named variables using text/template syntax.
• Translation files are simple JSON or YAML.
• Documented and tested!

Package i18n

The i18n package provides runtime APIs for fetching translated strings.

Command goi18n

The goi18n command provides functionality for managing the translation process.

Installation

Make sure you have setup GOPATH.

go get -u github.com/Compufreak345/go-i18n/goi18n
goi18n -help

Workflow

A typical workflow looks like this:

1. Add a new string to your source code.

   T("settings_title")

2. Add the string to en-US.all.json

   [
     {
       "id": "settings_title",
       "translation": "Settings"
     }
   ]

3. Run goi18n

   goi18n path/to/*.all.json
   

4. Send path/to/*.untranslated.json to get translated.

5. Run goi18n again to merge the translations

   goi18n path/to/*.all.json path/to/*.untranslated.json

Translation files

A translation file stores translated and untranslated strings.

Example:

[
  {
    "id": "d_days",
    "translation": {
      "one": "{{.Count}} day",
      "other": "{{.Count}} days"
    }
  },
  {
    "id": "my_height_in_meters",
    "translation": {
      "one": "I am {{.Count}} meter tall.",
      "other": "I am {{.Count}} meters tall."
    }
  },
  {
    "id": "person_greeting",
    "translation": "Hello {{.Person}}"
  },
  {
    "id": "person_unread_email_count",
    "translation": {
      "one": "{{.Person}} has {{.Count}} unread email.",
      "other": "{{.Person}} has {{.Count}} unread emails."
    }
  },
  {
    "id": "person_unread_email_count_timeframe",
    "translation": {
      "one": "{{.Person}} has {{.Count}} unread email in the past {{.Timeframe}}.",
      "other": "{{.Person}} has {{.Count}} unread emails in the past {{.Timeframe}}."
    }
  },
  {
    "id": "program_greeting",
    "translation": "Hello world"
  },
  {
    "id": "your_unread_email_count",
    "translation": {
      "one": "You have {{.Count}} unread email.",
      "other": "You have {{.Count}} unread emails."
    }
  }
]
