I need to do a bunch of word replacements in a file and want to do it with a vi command, not an EX command such as :%s///g
.
I know that this is the typical way one replaces the word at the current cursor position: cw<text><esc>
but is there a way to do this with the contents of the unnamed register as the replacement text and without overwriting the register?
12yl
to yank 12 characters and "_cw^r0
to replace a word. I was then able to use the .
command to repeat the replacement throughout the file.
I'm thinking by "paste" you mean the unnamed (yank/put/change/delete/substitute) register, right? (Since that's the one that'd get overwritten by the change command.)
Registers are generally specified by typing "
then the name (single character) of the register, like "ay
then "ap
to yank into register a
, then put the contents of register a
. Same goes for a change command. In this case, if you don't want the text you remove with the change command to go anywhere, you can use the black hole register "_
: "_cw
. Then once in insert mode, you can hit ctrl-R followed by the register you want (probably "
) to put in the contents of that register.
"* - selection register (middle-button paste)
"+ - clipboard register (probably also accessible with ctrl-shift-v via the terminal)
"" - vim's default (unnamed) yank/put/change/delete/substitute register.
Short answer: "_cw^R"
Edit: as others are suggesting, you can of course use a different register for the yank (or whatever) that got your text into the default register. You don't always think of that first, though, so it's nice to do a single change command without blowing it away. Though it's not totally blown away. There are the numbered registers "0
through "9
:
Vim fills these registers with text from yank and delete commands. Numbered register 0 contains the text from the most recent yank command, unless the command specified another register with ["x]. Numbered register 1 contains the text deleted by the most recent delete or change command, unless the command specified another register or the text is less than one line (the small delete register is used then). An exception is made for the delete operator with these movement commands: %, (, ), `, /, ?, n, N, { and }. Register "1 is always used then (this is Vi compatible). The "- register is used as well if the delete is within a line. With each successive deletion or change, Vim shifts the previous contents of register 1 into register 2, 2 into 3, and so forth, losing the previous contents of register 9.
Using the information in this post, I have formed this useful mapping. I chose 'cp' because it signifies "change paste"
nmap <silent> cp "_cw<C-R>"<Esc>
EDIT:
Also I took this a step further and supported any motion.
To get the equivalent of command above it would be cpw
for "change paste word"
"This allows for change paste motion cp{motion}
nmap <silent> cp :set opfunc=ChangePaste<CR>g@
function! ChangePaste(type, ...)
silent exe "normal! `[v`]\"_c"
silent exe "normal! p"
endfunction
nmap <silent> cp :let g:currentRegister=v:register<cr>:set opfunc=ChangePaste<CR>g@ function! ChangePaste(type, ...) silent exe "normal! `[v`]\"_c".getreg(g:currentRegister) endfunction
You can use the visual mode of vim for this. e.g. copy a word: ye
and then overwrite another one with the copied word: vep
If your cursor is on the word you want to replace with the contents of the unnamed register, you can use viwp
. v
switches to visual mode, iw
selects the inner word, and p
puts the contents of the register in its place.
In practice, when I need to replace one word (function name, etc.) with another, I'll move to the one to use as a replacement, yiw
to yank the inner word to the unnamed register, then move to the word I'm replacing, and viwp
to replace it. Pretty quick way of substituting one word for another. If you searched (/
) for the word you're replacing to get to it, you can then just hit n
to get to the next occurrence you need to replace. Obviously no substitute for using :%s/find/replace/g
, but for a couple of quick substitutions it can be handy, especially if you already have the new word in a register.
If you make use of a named register (ie. use "ay
or "ad
, etc., to fill your paste register), you can do something like
cw<CTRL-R>a<esc>
Which will replace the word with the contents of register a
. As far as I can tell, you can't use the default register because when you cw
it'll be filled with the word that was cut by that command.
ciw<CTRL-R>a<esc>
if you don't want to first go to the beginning of the word
Do you mean the system paste buffer or the vi register?
If you want to use the system paste buffer then you are fine and could do dw"+P
- "
chooses a register, and "+
is the system paste buffer.
Otherwise copy into the non-default register with say "ay
to copy into register a
and then to replace something do dw"aP
dw
deletes trailing whitespace after what I would consider the "word," whereas cw
only changes the word. For that reason, dw
won't work for me.
de
should work for you - it will delete to the end of this word, while dw
will delete to the start of the next word.
You can use yw
to yank the word, then you can change the word with yanked word by vipw
to yank word and paste previously yanked word.
You can use registers for that:
first place replacement text in register <mark some text>"ay
where a
is register name
then you can use that register in replacement
ve"ap
.
, which is another thing I wanted to do. Thanks, though. Much appreciated.
Or you could do Shift+v-p (select the whole line and paste in its' place)
