# gosexy/gettext
Go bindings for [GNU gettext][1], an internationalization and localization
library for writing multilingual systems.
## Requeriments
The GNU C library. If you're using GNU/Linux, FreeBSD or OSX you should already
have it.
## Installation
Use `go get` to download and install the binding:
```sh
go get github.com/gosexy/gettext
```
## Usage
```go
package main
import (
"github.com/gosexy/gettext"
"fmt"
"os"
)
func main() {
gettext.BindTextdomain("example", ".")
gettext.Textdomain("example")
os.Setenv("LANGUAGE", "es_MX.utf8")
gettext.SetLocale(gettext.LC_ALL, "")
fmt.Println(gettext.Gettext("Hello, world!"))
}
```
You can use `os.Setenv` to set the `LANGUAGE` environment variable or set it
on a terminal:
```sh
export LANGUAGE="es_MX.utf8"
./gettext-program
```
Note that `xgettext` does not officially support Go syntax yet, however, you
can generate a valid `.pot` file by forcing `xgettest` to use the C++
syntax:
```sh
xgettext -d example -s gettext_test.go -o example.pot -L c++ -i \
--keyword=NGettext:1,2 --keyword=Gettext
```
This will generate a `example.pot` file.
After translating the `.pot` file, you must generate `.po` and `.mo` files and
remember to set the UTF-8 charset.
```sh
msginit -l es_MX -o example.po -i example.pot
msgfmt -c -v -o example.mo example.po
```
Finally, move the `.mo` file to an appropriate location.
```sh
mv example.mo examples/es_MX.utf8/LC_MESSAGES/example.mo
```
## Documentation
You can read `gosexy/gettext` documentation from a terminal
```sh
go doc github.com/gosexy/gettext
```
Or you can [browse it](http://godoc.org/github.com/gosexy/gettext) online.
The original gettext documentation could be very useful as well:
```sh
man 3 gettext
```
Here's another [good tutorial][2] on using gettext.
