Multiply/divide by [count]

8 years ago

Same as <C-a> and <C-x> but multiplies and divides by [count] instead.

TODO: make it repeatable.

function! Multivide(divide)
    let cnt = v:count1
    let old_reg = getreg("v")
    let raw_number = getreg("v")
    call search('\d\([^0-9\.]\|$\)', 'cW')
    normal v
    call search('\(^\|[^0-9\.]\d\)', 'becW')
    normal "vygv
    if a:divide == 1
        execute 'normal "_c' . @v / cnt
    else
        execute 'normal "_c' . @v * cnt
    endif
    call setreg("v", old_reg)
endfunction
