# Translates entries of RSS 2.0 feed into different locale.
|
|
#
|
|
# Make sure to have all dependencies installed:
|
|
# pip3 install googletrans
|
|
# pip3 install asyncio (if using parallel version of the script)
|
|
# pip3 install hyper (for HTTP/2 support, much faster than default)
|
|
#
|
|
# You must provide raw RSS 2.0 UTF-8 feed XML data as input, for example with curl:
|
|
# curl 'https://phys.org/rss-feed/' | python ./translate-feed.py "en" "pt_BR" "true"
|
|
#
|
|
# You must provide three command line arguments:
|
|
# translate-feed.py [FROM-LANGUAGE] [TO-LANGUAGE] [RUN-PARALLEL]
