Vim hackery.

README.markdown

Annoyed that the Perl debugger thinks each entered line should be immediately evaluated? It's hard to paste in a multi-line sub definition that way. Add escape-newlines.vim into ~/.vimrc.

How it works:

1. visually-select multiple lines
2. Type "+\e. (If your mapleader is set to something else, use it instead of \).
3. The contents of your clipboard will now be the selected lines with \ appended to each.

• It won't affect your buffer.
• It supports yanking into arbitrary registers.
• You can run the command directly if you want to operate on a numerical range and pass it a register name: :20,+10EscapeNewlines "

escape-newlines.vim

" Function that appends a '\' to the end of each line in the given range.
" Does not affect the buffer.
function! s:EscapeNewlines(reg, line1, line2)
    let lines = map(getline(a:line1, a:line2), 'v:val . (empty(v:val) ? "\\" : " \\")')
    let reg = empty(a:reg) ? '"' : a:reg        " default to unnamed register
    execute 'let @' . reg . ' = join(lines, "\n") . "\n"'
    echomsg a:line2 - a:line1 + 1 . ' lines escaped+yanked into register ' . reg
endfunction
command! -register -range EscapeNewlines call <SID>EscapeNewlines(<q-reg>, <line1>, <line2>)

" Define visual- and normal-mode maps to put the \ lines into the current
" register.  These also work with ranges.
