go-i18n

Git i18n demo

Use gettext as i18n framework for go project.

$ make
$ ./go-i18n po/build/locale

Mark your code

Import "i18n" package in your code, e.g.:

import "github.com/jiangxin/go-i18n/i18n"

Setup locale dir and use default language, and returns a locale instance.

l := i18n.Setup("/opt/demo/share/locale", "demo")

Mark string using the wrappers provided by i18n package:

fmt.Print(l.L_("Hello, world.\n"))

Extract marked string into a template file: po/xx.pot

Extract marked strings in source code using xgettext. But you can use the wrapper in Makefile:

make pot

It will extract i18n strings into a template file: po/go-i18n.pot.

See file makefile.i18n. It is borrowed from Git project.

Prepare to translate

As a l10n translater, prepare your language file for translate. You can use msgmerge, but you can also use the wrapper in Makefile:

make po-init PO_FILE=po/zh_CN.po

This command will create a language file for Simplified Chinese translation.

You can also create language file for other languages, such as:

make po-init PO_FILE=po/zh_TW.po
make po-init PO_FILE=po/fr.po

Please note: use locale name as your langue file. See your locale code by running:

locale -a | sed 's/\..*$//g' | sort

Start to translate your language file

It is recommended that you use Emacs with po mode as the editor for po files.

Compile language files

You can use msgfmt to compile .po files into compiled .mo files, but you can also use wapper in Makefile:

make po/zh_CN.mo

Install

Install compiled language files in proper location with your program, and your program can speak multiple languages.
