# 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 probably
already have it.
## Installation
Use `go get` to download and install the binding:
```sh
go get github.com/gosexy/gettext
```
## Usage
This is an example program showing the `BindTextdomain`, `Textdomain` and
`SetLocale` bindings:
```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!"))
}
```
Set the `LANGUAGE` env to the name of the language you want to use in your
program:
```sh
export LANGUAGE="es_MX.utf8"
./myapp
```
You can use the `xgettext` command to extract strings to be translated from a
Go program:
```
go get github.com/gosexy/gettext/go-xgettext
xgettext -o outfile.pot --keyword=Gettext --keyword-plural=NGettext -i infile.go
```
This will generate a `example.pot` file.
After actually translating the `.pot` file, you'll have to generate `.po` and
`.mo` files with `msginit` and `msgfmt`:
```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
Check out the API documentation [godoc.org/github.com/gosexy/gettext)](http://godoc.org/github.com/gosexy/gettext).
The original gettext documentation:
```sh
man 3 gettext
```
And here's a [good tutorial][2] on using gettext.
