|
|
Convert Flask-Babel locale codes to timeago library locale codes.
|
|
|
|
The Python timeago library (https://github.com/hustcc/timeago) supports 48 locales
|
|
but uses different naming conventions than Flask-Babel. This function maps between them.
|
|
|
|
Notable differences:
|
|
- Chinese: Flask uses 'zh', timeago uses 'zh_CN'
|
|
- Portuguese: Flask uses 'pt', timeago uses 'pt_PT' or 'pt_BR'
|
|
- Swedish: Flask uses 'sv', timeago uses 'sv_SE'
|
|
- Norwegian: Flask uses 'no', timeago uses 'nb_NO' or 'nn_NO'
|
|
- Hindi: Flask uses 'hi', timeago uses 'in_HI'
|
|
- Czech: Flask uses 'cs', but timeago doesn't support Czech - fallback to English
|
|
|
|
Args:
|
|
flask_locale (str): Flask-Babel locale code (e.g., 'cs', 'zh', 'pt')
|
|
|
|
Returns:
|
|
str: timeago library locale code (e.g., 'en', 'zh_CN', 'pt_PT')
