Paste above or below the current line

[mantzu132]

Hi !

In neovim I have keybind [p to paste above the current line:

-- #Paste Above
vim.keymap.set("n", "[p", '<Cmd>exe "put! " . v:register<CR>', {
    desc = "Paste Above",

I have one for pasting below the current line but it's the same thing basically.

I tried to copy this to Helix:

[keys.normal."["]
P = [ "open_above","normal_mode", "paste_before","goto_line_start"]

It works fine IF I don't copy the newline character when copying the text. If I do, then there will end up being an extra empty line which I don't want. In neovim, this extra empty line doesn't happen for some reason.

Doesn't work even if I do paste_after instead of paste_before

Then I tried this :

[keys.normal."["]
P = [ "open_above","normal_mode", "replace_with_yanked","goto_line_start"]

It works fine IF I copy the newline character when copying text, but doesn't if I don't copy it (say I copy only a word)

How do I make [P work in both ways? This is a pretty important keybind for me. In neovim it works fine both ways.

Sorry if I'm missing the point, but did you try trimming the selection before moving to paste it?

here're snippets from my yank/paste-ing sections

[keys.normal.y]
j = [ 'save_selection', 'trim_selections', 'yank_joined', 'jump_backward' ]
y = 'yank'
c = [ 'trim_selections', 'yank' ]
l = [ 'save_selection', 'extend_line', 'yank', 'jump_backward' ]

[keys.normal.p]
o = { l = [ 'extend_line', 'delete_selection_noyank', 'paste_before' ], w = [ 'move_prev_word_start', 'extend_next_word_end', 'delete_selection_noyank', 'paste_before' ], c = ':clipboard-paste-replace', o = 'replace_with_yanked', t = [ 'trim_selections', 'delete_selection_noyank', ':insert-output tpb' ] }

Before yanking? trim_selections just de-selects the whitespace at the end of the text.

I brushed it off as I was thinking what to do when pasting not yanking.

But it does kinda work with the paste_before example in my post.

However:

1. I need to re-bind my yank command to do trim_selections before yanking.
2. Doesn't solve the issue when I copy stuff from outside the editor. Sometimes copying code from my browser I copy the newline at the end and it gives that same extra line when pasting in Helix.

A bit of a messier than I would like it to be. I don't want to re-bind yank just for this or create a new key-bind altogether.

Again, in neovim it just works in all cases perfectly.

Replace the opened line with the register, then pipe it so it always ends in one newline.

[keys.normal."["]
p = [
  "open_above",
  "normal_mode",
  "extend_to_line_bounds",
  "replace_with_yanked",
  ":pipe python3 -c \"import sys; sys.stdout.write(sys.stdin.read().rstrip('\\n')+'\\n')\"",
  "goto_line_start",
]

[keys.normal."]"]
p = [
  "open_below",
  "normal_mode",
  "extend_to_line_bounds",
  "replace_with_yanked",
  ":pipe python3 -c \"import sys; sys.stdout.write(sys.stdin.read().rstrip('\\n')+'\\n')\"",
  "goto_line_start",
]

Helix already treats a trailing newline as linewise, so open_above plus paste_before is what adds the extra blank. This stays on the paste side, so a browser copy works if you prefix "+. You do not need to rebind yank. Needs python3 on PATH. On a comment line, O may continue the comment leader.
