UUID generator for vim. Inputs a uuid to copy buffer

vimrc

fu! GenerateUUID()

python << EOF
import uuid
import vim

# output a uuid to the vim variable for insertion below
vim.command("let generatedUUID = \"%s\"" % str(uuid.uuid4()))

EOF

" insert the python generated uuid into the current cursor's position
:execute "normal i" . generatedUUID . ""

endfunction

"initialize the generateUUID function here and map it to a local command
noremap <Leader>r :call GenerateUUID()<CR>

Works great! FYI I had to change

python << EOF

to

py3 <<EOF

to get it to work. C.f. https://github.com/ensime/ensime-vim/issues/306#issuecomment-359591407
