"""Convert CLDR data to QLocaleXML
|
|
|
|
The CLDR data can be downloaded from CLDR_, which has a sub-directory
|
|
for each version; you need the ``core.zip`` file for your version of
|
|
choice (typically the latest). This script has had updates to cope up
|
|
to v38.1; for later versions, we may need adaptations. Unpack the
|
|
downloaded ``core.zip`` and check it has a common/main/ sub-directory:
|
|
pass the path of that root of the download to this script as its first
|
|
command-line argument. Pass the name of the file in which to write
|
|
output as the second argument; either omit it or use '-' to select the
|
|
standard output. This file is the input needed by
|
|
``./qlocalexml2cpp.py``
|
|
|
|
When you update the CLDR data, be sure to also update
|
|
src/corelib/text/qt_attribution.json's entry for unicode-cldr. Check
|
|
this script's output for unknown language, territory or script messages;
|
|
if any can be resolved, use their entry in common/main/en.xml to
|
|
append new entries to enumdata.py's lists and update documentation in
|
|
src/corelib/text/qlocale.qdoc, adding the new entries in alphabetic
|
|
order.
|
|
|
|
While updating the locale data, check also for updates to MS-Win's
|
|
time zone names; see cldr2qtimezone.py for details.
|
|
|
|
All the scripts mentioned support --help to tell you how to use them.
