faraj.libratranslateHost and libratranslatePort, according to where libratranslate is running. e.g libratranslate --host 192.168.1.5 --port 5555; Then 192.168.1.5, and 5555 would crosspond to the host and port respectively.
faraj.insertAfter default true, if false, the selected text would be replaced with tranlsation. I opted to make it on, because I assume one mostly need to adjust translated text, would need to compare with orignal then.
Usage
Just select any text in any file, then open command pallet, search for, Translate the selected...etc.
Limitaion
Only translate to/from English, Arabic. Woiudl make it configurable if/when time allows.
Changing any setting or config, requires to restart VS code.
