gettext - Ruby-GetText-Package¶ ↑

Ruby-GetText-Package is a Localization(L10n) library and tool

which is modeled after the GNU gettext package.

This library translates original messages to localized

messages using client-side locale information(environment

variable or CGI variable).

The tools for developers support creating, useing, and modifying

localized message files(message catalogs).

((Rails)) Rails support has been removed.

Rails / ActiveRecord specific code now lives in locale_rails, gettext_rails and gettext_activerecord.

Features¶ ↑

Translate singular/plural messages with simple APIs(similar to GNU gettext)
Thread safety. Message resources are shared from all threads, but returns translated messages of the current thread’s locale.
Tools to find message IDs
- Extract message IDs to po-files using rgettext from
  - ruby scripts
  - glade-2 XML file(.glade)
  - ERB file(.rhtml, .erb)
  - Anything (with your own parsers)
  - The po-files are compatible to GNU gettext.
- rmsgfmt creates a mo-file from a po-file. The mo-file is compatible to GNU gettext(msgfmt).
- Using rgettext/rmsgfmt as Rake tasks
textdomain’s scope is adapt to ruby class/module mechanism.
- A class/module can have plural textdomains.
- a message is looked up in its class/module and ancestors.
CGI support (gettext/cgi)
- Locale is retrieved from client informations using Ruby-Locale. (HTTP_ACCEPT_LANGUAGE, HTTP_ACCEPT_CHARSET, QUERY_STRING(lang), Cookies(lang)).
String%() is extended to use named argument such as %{foo}" %{:foo => 1}. Notes that Ruby-1.9.x supports this format by itself.

Requirements¶ ↑

Ruby 1.8.3 or later
Rubygems
locale gem
- $ gem install locale
(for development only)
- GNU gettext 0.10.35 or later
- Racc-1.4.3 or later
  - (for compiling src/rmsgfmt.ry only)

Install¶ ↑

Uninstall old gettext if exists. (You need to do this when updating 1.93.0 -> 2.0.1)
```
(sudo/su on POSIX system)
gem uninstall gettext
```

gem

#from rubyforge 
(sudo/su on POSIX system)
gem install gettext

download tar-ball

# De-Compress archive and enter its top directory.
(sudo/su on POSIX system)
ruby setup.rb

You can also install files in your favorite directory by

supplying setup.rb some options. Try ruby setup.rb --help.

Usage¶ ↑

Translation¶ ↑

_: Basic translation method Translates the message.
```
_("Hello")
```

The gettext methods comes in 3 combinable flavors

n: Pluralized Returns singular or plural form, depending on how many you have.
```
n_("Apple", "%{num} Apples", 3)
n_(["Apple", "%{num} Apples"], 3)
```
p: context aware A context is a prefix to your translation, usefull when one word has different meanings, depending on its context.
```
p_("Printer","Open") <=> p_("File","Open")
is the same as s_("Printer|Open")  <=> s_("File|Open")
```

s: without context If a translation could not be found, return the msgid without context.

s_("Printer|Open") => "Öffnen" #translation found
s_("Printer|Open") => "Open"   #translation not found

combinations

np_("Fruit", "Apple", "%{num} Apples", 3)
ns_("Fruit|Apple","%{num} Apples", 3)

np_(["Fruit","Apple","%{num} Apples"], 3)
ns_(["Fruit|Apple","%{num} Apples"], 3)

N_, Nn_: Makes dynamic translation messages readable for the gettext parser. _(fruit) cannot be understood by the gettext parser. To help the parser find all your translations, you can add fruit = N_("Apple") which does not translate, but tells the parser: “Apple” needs translation.
```
fruit = N_("Apple")   # same as fruit = "Apple"
_(fruit)              # does a normal translation

fruits = Nn_("Apple", "%{num} Apples")
n_(fruits, 3)
```

Bind textdomains to the classes.¶ ↑

A textdomain has a translation file in each language. A module/class can have multi textdomains. This means the libraries/applications can have their own textdomains.

class Foo
  include GetText
  bindtextdomain "your_app_domain_name"
end

class Book
  include GetText
  bindtextdomain "general"
  bindtextdomain "book"
end

Locale¶ ↑

If you need to set the locale by yourself, then use:

GetText.locale = "en_US" # translate into english from now on
GetText.locale # => en_US

include GetText
set_locale "en_US"

For more details and options, have a look at the samples folder or consult the tutorial.
