#Extracting UI Strings

These instructions describe how to extract UI strings so that they can be translated. The original source of these instructions, stored on Assembla, is here: [1]

##Markup for internationalized strings in the code

In the code, whenever developers write strings that will have to be translated, they use a special function whose name consists of a double underscore. A script (CakePHP's "i18n extract" script) can later be run to scan the code and extract the strings that are passed to this function.

__() function

CakePHP has several functions in this vein, but this is the function we will use most of the time. Note the pair of underscores.

    __(‘some text’) => echo ‘some text’;
    __(‘some text’, true) => return ‘some text’;

The language used in the code will be English.

##Running cake i18n (on a Linux machine or virtual machine)

    Open a console.
    Type : /var/http/tatoeba/cake/console/cake i18n
    Choose : E (Extract POT file from source)
    When asked if you want to merge all translations into a single file, say yes
    Type in the path to app: /home/tatoeba/tatoeba-www/app
    Type in the path to locale: /home/tatoeba/tatoeba-www/app/locale
    Choose a name for the file that will be generated (in this example, default.pot): default.pot
    Choose: Q (quit)

##PO file

Note: it may be better to use Launchpad to create a new UI language rather than follow this manual procedure.

Adding a new language (e.g., French):

    Create folder : /app/locale/fre/LC_MESSAGES
    Copy-paste default.pot in this folder
    Change it into default.po
    Open default.po with PoEdit (http://www.poedit.net/) and translate.
    Save. It will generate a *.mo file, which is used when replacing strings at runtime.

If new strings are added:

    Follow the cake i18n instructions to generate the up-to-date POT file.
    Open the PO file (PO, not POT).
    In the menu : Catalog > Update from POT file…
    Choose the POT file that was newly generated
