# This example shows how to implement i18n (internationalization) l10n (localization) to create
|
|
# multi-language bots with middleware handler.
|
|
#
|
|
# Note: For the sake of simplicity of this example no extra library is used. However, it is recommended to use
|
|
# better i18n systems (gettext and etc) for handling multilingual translations.
|
|
# This is not a working, production-ready sample and it is highly recommended not to use it in production.
|
|
#
|
|
# In this example let's imagine we want to introduce localization or internationalization into our project and
|
|
# we need some global function to activate the language once and to use that language in all other message
|
|
# handler functions for not repeatedly activating it.
|
|
# The middleware (i18n and l10n) is explained:
