Pasting text into a terminal running Vim with automatic indentation enabled can destroy the indentation of the pasted text. This tip shows how to avoid the problem.
See how to stop auto indenting for automatic indentation issues while you are typing.
If you use Vim commands to paste text, nothing unexpected occurs. The problem only arises when pasting from another application, and only when you are not using a GUI version of Vim.
In a console or terminal version of Vim, there is no standard procedure to paste text from another application. Instead, the terminal may emulate pasting by inserting text into the keyboard buffer, so Vim thinks the text has been typed by the user. After each line ending, Vim may move the cursor so the next line starts with the same indent as the last. However, that will change the indentation already in the pasted text.
Vim provides the 'paste' option to aid in pasting text unmodified from other applications. You can set it manually like:
:set paste :set nopaste
Or, Vim offers the 'pastetoggle' option to conveniently turn 'paste' on and off with one keypress.
Put the following in your vimrc (change <F2> to whatever key you want):
To paste from another application:
- Start insert mode.
- Press F2 (toggles the
- Use your terminal to paste text from the clipboard.
- Press F2 (toggles the
Then the existing indentation of the pasted text will be retained.
You do not have to start insert mode first, but if you are in normal mode and have a mapping for F2, that mapping will apply, and the
'pastetoggle' function will not operate.
Some people like the visual feedback shown in the status line by the following alternative for your vimrc:
nnoremap <F2> :set invpaste paste?<CR> set pastetoggle=<F2> set showmode
The first line sets a mapping so that pressing F2 in normal mode will invert the
'paste' option, and will then show the value of that option. The second line allows you to press F2 when in insert mode, to toggle
'paste' on and off. The third line enables displaying whether
'paste' is turned on in insert mode.
For VIM running in recent terminals, you can use the excellent vim-bracketed-paste plugin which automatically sets
'paste' option when, well, pasting.
- Thanks for your fix Spiiph, and please check what I changed. I think the following is now attended to, and all these old comments can be deleted after a few days. JohnBeckett 01:39, January 13, 2010 (UTC)
I've applied this tip (under VIM 7.2), but when pressing F2 under insert mode it cycles through 3 different modes:
-- (insert) -- -- INSERT (paste) -- -- INSERT --
So I have to hit F2 twice under insert mode to enter paste mode. Using this worked for me:
nnoremap <F2> :set invpaste paste?<CR> imap <F2> <C-O>:set invpaste paste?<CR> set pastetoggle=<F2>
- Who's 'me'? The
imapis superfluous. I'm not sure why it was there from the start, since the
'showmode'option displays whether
'paste'is turned on or not.(Spiiph 12:08, January 12, 2010 (UTC))
