"""Translation methods for generating localized strings.
|
|
|
|
To load a locale and generate a translated string::
|
|
|
|
user_locale = tornado.locale.get("es_LA")
|
|
print user_locale.translate("Sign out")
|
|
|
|
`tornado.locale.get()` returns the closest matching locale, not necessarily the
|
|
specific locale you requested. You can support pluralization with
|
|
additional arguments to `~Locale.translate()`, e.g.::
|
|
|
|
people = [...]
|
|
message = user_locale.translate(
|
|
"%(list)s is online", "%(list)s are online", len(people))
|
|
print message % {"list": user_locale.list(people)}
|
|
|
|
The first string is chosen if ``len(people) == 1``, otherwise the second
|
|
string is chosen.
|
|
|
|
Applications should call one of `load_translations` (which uses a simple
|
|
CSV format) or `load_gettext_translations` (which uses the ``.mo`` format
|
|
supported by `gettext` and related tools). If neither method is called,
|
|
the `Locale.translate` method will simply return the original string.

|
|
|
|
Translations are strings with optional Python-style named placeholders
|
|
(e.g., ``My name is %(name)s``) and their associated translations.
|
|
|
|
The directory should have translation files of the form ``LOCALE.csv``,
|
|
e.g. ``es_GT.csv``. The CSV files should have two or three columns: string,
|
|
translation, and an optional plural indicator. Plural indicators should
|
|
be one of "plural" or "singular". A given string can have both singular
|
|
and plural forms. For example ``%(name)s liked this`` may have a
|
|
different verb conjugation depending on whether %(name)s is one
|
|
name or a list of names. There should be two rows in the CSV file for
|
|
that string, one with plural indicator "singular", and one "plural".
|
|
For strings with no verbs that would change on translation, simply
|
|
use "unknown" or the empty string (or don't include the column at all).
|
|
|
|
The file is read using the `csv` module in the default "excel" dialect.
|
|
In this format there should not be spaces after the commas.
|
|
|
|
If no ``encoding`` parameter is given, the encoding will be
|
|
detected automatically (among UTF-8 and UTF-16) if the file
|
|
contains a byte-order marker (BOM), defaulting to UTF-8 if no BOM
|
|
is present.
|
|
|
|
Example translation ``es_LA.csv``::
|
|
|
|
"I love you","Te amo"
|
|
"%(name)s liked this","A %(name)s les gustó esto","plural"
|
|
"%(name)s liked this","A %(name)s le gustó esto","singular"
