# This patch performs 2 functions
|
|
#
|
|
# 1. It caches all translations which drastically improves
|
|
# translation performance in an LRU cache
|
|
#
|
|
# 2. It patches I18n so it only loads the translations it needs
|
|
# on demand
|
|
#
|
|
# This patch depends on the convention that locale yml files must be named [locale_name].yml
