Bonjour, comment va?Apprenons a programmer

Connaissez-vous Kano?

Je m’appelle Jean

Que voudrais-tu fabriquer?

Jouons a un jeu!

Je vais te raconter une histoire

Translate Kano Apps

What is i18n?

= internationalization

modify a program to make it possible to support other languages

l11n = localization

add support for a foreign language to a program translation + ...

gettext intro... print _(“Hello, my name is Kano”) ...

Program: myapp-main.py

... src/myapp-main.py ...

PYPOTFILES: List of files to be processed by xgettext

#: src/myapp-main.py:36 msgid "Hello, my name is Kano" msgstr ""

Translation template: messages.pot

#: src/myapp-main.py:36 msgid "Hello, my name is Kano" msgstr "こんにちは、Kanoと言います。"

Japanese translation: ja.po

#: src/myapp-main.py:36 msgid "Hello, my name is Kano" msgstr "Bonjour, je m’appelle Kano"

French translation: fr.po

i18n tips● Use .format instead of %s, %d ● Use named params instead of

positional params: _(“Today is {} {}”) _(“Today is {month} {day}”)

● Write comments for the translators ● Do not split sentences:

_(“this is a “) + car.color + _(“car”) _(“this is a {color} car”).format(color=car.color)

● Avoid including HTML in strings: _(“<em>Welcome!</em>”) u”<em>” + _(“Welcome!”) + u”</em>”

I18n of Terminal Quest

● Mark UI visible strings ● Update format (parameters etc) ● Copy ASCII art folder for each language ● Typewriter ○ Fix width computation (for wide characters) ○ Fix word-wrapping algorithm (for lg with no space)

● Adjust buffer size (for multi-byte strings)

Internationalisation is not just translation!

● Python UI using gtk

● Content (challenges) in JSON format

How to switch Kano (RPi) to Japanese

$ sudo dpkg-reconfigure locales en_GB.UTF-8 UTF-8 ja_JP.EUC-JP EUC-JP * ja_JP.UTF-8 UTF-8

$ apt-get install ttf-kochi-gothic xfonts-intl-japanese xfonts-intl-japanese-big xfonts-kaname

Open issues for Japanese support in Kano

• IME (support Japanese input)

• i18n support for apps not (yet) open source

• Translation timing vs release timing

• Translation of community site
