Instructions for translators¶
Here is how your can help translating Lino into your own language.
Before starting to translate, you must have installed a contributor environment of Lino.
You are going to edit a series of
.po files which are part of the Lino
source code. Each Lino repository has its own series of
Their place is given by the
locale_dir setting (see
Project configuration settings). Here are some examples:
Adding support for a new language to translate¶
Before you can start translating to a language, you must check whether the repository already has translation files for your language.
If you want to translate to a language for which Lino does not yet have any translations,
Lino uses the same language codes as Django. You can see the list of available languages in django/conf/global_settings.py.
After adding a language, you must run
inv mm, which will ask your
configuration before creating the new catalog files.
Set up a site¶
Let's say for example that you want to translate to Spanish.
Don't simply translate all the messages in the
django.po files because
some translations depend on the context. It's better that you see where a message is being used before you decide how to translate it.
you won't need to translate all the messages. It's more efficient to focus on the most important ones.
That's why we recommend that you use a demo project to see your work while you are evolving.
Go to some local project directory (e.g. the one you created in Installing a Lino developer environment):
$ go first
Change your project's
settings.py file once more so that it
looks as follows:
# -*- coding: UTF-8 -*- from lino_book.projects.min9.settings import * class Site(Site): title = "My Lino Mini site" languages = 'en es' SITE = Site(globals())
That is, you specify your own language distribution (in the
lino.core.site.Site.languages setting) consisting of English as first
language and Spanish (your language) as second. The first language cannot
currently be your language because some demo fixtures would fail
If your language is not yet covered for Lino, then you must Create a demo user for your language before going on.
Initialize the demo database:
$ python manage.py prep
Run the development server:
$ python manage.py runserver
Point your browser to view the application. Log in as the Spanish user.
Find the strings that you want to translate¶
The translatable strings on this page (gettext and Poedit call them "messages") are for example the menu labels ("Contacts", "Products" etc), but also content texts like "Welcome", "Hi, Rodrigo!" or "This is a Lino demo site."
Now you must find out which
django.po file contains these strings. Open
another terminal window and use grep to find the file:
$ grep -H Contacts ~/repositories/lino/lino/locale/es/LC_MESSAGES/*.po /home/repositories/work/lino/lino/locale/es/LC_MESSAGES/django.po:#~ msgid "Contacts" $ grep -H Contacts ~/repositories/xl/lino_xl/lib/xl/locale/es/LC_MESSAGES/*.po /home/luc/repositories/xl/lino_xl/lib/xl/locale/es/LC_MESSAGES/django.po:msgid "Contacts" /home/luc/repositories/xl/lino_xl/lib/xl/locale/es/LC_MESSAGES/django.po:msgid "Client Contacts" /home/luc/repositories/xl/lino_xl/lib/xl/locale/es/LC_MESSAGES/django.po:#~ msgid "Contacts"
Launch Poedit on the
django.po file for the Spanish translation:
$ poedit lino/locale/es/LC_MESSAGES/django.po
It looks similar to this screenshot:
Translate one or a few messages. In our example we translated the following message:
Save your work in Poedit. Poedit will automatically compile the
django.po file into a corresponding
Now you should first touch your settings.py file in order to tell runserver that something has changed. Open a third terminal window and type:
$ go first $ touch settings.py
This will cause the server process (which is running in the first terminal window) to reload and to rewrite any cache files.
Refresh your browser page:
Submit your work¶
When you are satisfied with your work, you must make a pull request to ask us to integrate your changes into the public Lino repositories.
More about pull requests in Basic git skills.
Create a demo user for your language¶
If Lino does not yet have a default site administrator user for your language
pm prep will say a
No demo user for language 'bn'.
This means that you should create a local fixture that creates it. It's easy:
$ mkdir fixtures $ touch fixtures/__init__.py $ nano fixtures/demo.py
demo.py file should look as follows:
# This is needed only if Lino does not yet have a default demo # administrator for your language. from django.conf import settings from lino.modlib.users.choicelists import UserTypes def objects(): yield settings.SITE.user_model(username="es_demo_root", language="es", first_name="Roberto", last_name="Spanish", email=settings.SITE.demo_email, profile=UserTypes.admin)
Trucs et astuces¶
Voici un pitfall: la traduction du string suivant:
msgid "%(person)s has been unregistered from %(course)s"
ne doit pas être:
msgstr "%(personne)s a été désinscrit du %(cours)"
msgstr "%(person)s a été désinscrit du %(course)s"
C.-à-d. les mots-clés entre parenthèses sont des variables, et il ne faut pas les modifier.
À noter également que le
s derrière la parenthèse ne sera pas
imprimé mais est obligatoire
(il indique à Python qu'il s'agit d'un remplacement de type string).
