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

Base64 encode/decode visual-selected region in buffer and clipboard, put this in ~/.vimrc, and use F2 to encode selection, and F3 to decode selection

" 1. base64-encode(visual-selection) -> F2 -> encoded base64-string
:vnoremap  c=system("base64 -w 0", @")

" 2. base64-decode(visual-selection) -> F3 -> decoded string
:vnoremap  c=system("base64 -d", @")
