How to execute ‘base64 --decode’ on selected text in Vim?

Question

I’m trying to execute base64 --decode on a piece of text selected in Visual mode, but it is the entire line that seems to be passed to the base64 comma

Answer 1

If you want to replace the text with the output of base64, use something like

:vnoremap 64 y:let @"=system('base64 --decode', @")gvP
