config option so x only deletes files from dir where last selection was made

[brett-mahar]

A few times, I have selected a few files to move, gone into the new directory, got distracted when I noticed stuff that needed deleting, selected that stuff, pressed x, and so accidently deleted the stuff I wanted to copy from the other directory.

Is there some way I can config my nnn to not delete from more than one directory at the same time? I never want to do this on purpose.

If there is no such option, I think it would be quite useful to have. Or even to change current behaviour to not allowing deleting from more than one dir at a time, just display an "error: cannot delete from more than one dir at a time" or whatever.

Its quite easy to delete a huge directory you were just trying to move, and not even realise till a long time later :-o

when you make selection you can delete(or other operations which supports this) for hovered file or selection(bottom left corner).

If you want to make multiple selections and delete selected from dirA while preserving dirB, you could make script to parse .selection and rm -rf things from dirA bind it to ;x or whatever.

Hey Daru,

Yes I did mean when doing multiple selections!

Anyway thanks to your advice I have written a plugin and bound to ;x via the NNN_PLUG='x:nnn-delete-pwd-only' env variable

Here's the script in case anyone's brain is like mine and forgets there is selected stuff in another folder:

#!/usr/bin/dash

cat .config/nnn/.selection | perl -pe 's/\0/\n/g' > /tmp/.selectedList
lastDir=$(cat /tmp/.selectedList | tail -n 1 | xargs dirname)
cat /tmp/.selectedList | grep $lastDir | xargs rm -rf

Cheers!

No. But you can use $NNN_TRASH + trash-cli to make it so that accidental deletes can be reverted back easily.

Oh thanks @N-R-K that's a good idea. I will use that in conjunction with my plugin script.

So I rewrote the "delete only from the last selected directory" plugin in Julia (less annoying to debug than the shell script version I posted earlier) and made it more rubust (so it can handle spaces, |, and other special characters in the filename, and not freak out if selction file is empty):

#!/usr/bin/env julia

raw = ""::String

function cleanup()
  sleep(2)
  run(`clear`)
  exit()
end

if isfile("/home/brett/.config/nnn/.selection") == false
  println("selection file does not exist")
  cleanup()
end

f = open("/home/brett/.config/nnn/.selection", "r")
  global raw = read(f, String)       
close(f)

splitArray = split(raw, "\u0")

if isempty(splitArray[1])
  println("nothing selected")
  cleanup()
end

lastDir = dirname(splitArray[length(splitArray)])

for i in 1:length(splitArray)
  if lastDir == dirname(splitArray[i])
    hasToGo = splitArray[i]
    println(" removing:", hasToGo)
    strrr = escape_string(hasToGo)
    rm(strrr, force=true, recursive=true)
  end
end

rm("/home/brett/.config/nnn/.selection", force=true)
cleanup()
