Is there a way of repeating a character while in Vim's insert mode? For example, say I would like to insert 80 dashes, in something like emacs I would type:
Ctrl+U 8 0 -
The only way I know how to do it in VIM is to exit normal mode for the repeat argument, then go back into insert mode to type the dash, then exit to insert the actual dashes, AND then go back into insert mode to carry on typing. The sequence is a really long:
Esc 8 0 a - Esc a
It would be nice not to switch in and out of modes.
If you are OK with leaving INSERT mode only once (at the end), this sequence works:
Ctrl+o 80i- Esc
80 the repetition, i to insert,- the character you want to insert,Another one without EVER leaving INSERT mode:
Ctrl+o :norm 8ia Return
There are many other ways but AFAIK the one you describe is the shortest one. In vim you are mostly supposed to spend your time in command mode, so that would be just 3 keystrokes + the number of repeats (80i-).
However, if you find that you very often use this repeat thing, you can make yourself a function or macro to that end; maybe something like:
:function Repeat(char)
: let counter = input("How many times?: ")
: call feedkeys("i")
: call feedkeys(repeat(a:char,counter))
:endfunction
:imap <C-U> <ESC>h"ryl :call Repeat(@r)<CR>
I'm surprised no one has suggested this yet:
In Insert mode, use <C-r>=repeat('-', 80)<CR>
That is:
repeat('-', 80)Works for repeating any character any number of times.
This uses more keystrokes than @romainl's answer, but does not leave Insert mode at all.
You said it would be 'nice' to stay in 'Insert' mode, however in Command Mode the following method would avoid your 2nd ESC :-
While I know this post is old, it seems a shame to miss the obvious 'Cut/Copy and Paste' option...
x ...cut
80 ...number of copies
p Paste
Note : This is similar to the method suggested by Martin Beckett, however I get a delay when issuing that command, perhaps because it switches modes several times, this command executes instantly.
Late answer but for what it's worth, if you wanna hand spam it, you can use the
"repeat last command" command: .
i "Phrase" Esc - i to insert, enter phrase/character, esc to go normal mode
. - Spam till you are satisfied. Will repeatedly input the phrase you typed (it repeats your last command).
I find this especially useful when I don't know exactly how many repeats I want to do, but know visually how long I want it to be. Basically blast the . till my eyes are content.
In addition to writing function that will repeat text multiple times, you could use <C-x><C-l>: if you already have line that contains 80 dashes, writing a few dashes at the start of new line and then pressing <C-x><C-l> will complete lines which start with these few dashes which will be likely that line with 80 dashes. I used to write horizontal lines (78 dashes) in help files in a such way.
For such an easy task abbreviation should do the trick. Add the following to your .vimrc
iab <expr> -- repeat('-', 80)
and from now, when you type -- followed by a space (while you are in insert mode), the -- will be automatically converted to - 80 times.
By using the function repeat you are able to repeat the string as many time you want.
Note that you can test it before updating the .vimrc by entering in command mode then issuing the following :iab <expr> -- repeat('-', 80)
I did this without exiting the INSERT mode using the below steps.
-- (insert) VISUAL -- mode)i - Ctrl+o v y Ctrl+o 80 p
This will print all the dashes horizontally in a single line.
