I'm pretty new to vim and I just learned that you can use dtx or dfx to delete up to x and up to and including x respectively. Is there a way to choose which occurrence of x to delete to?
For example, if I have the line
peter piper picked a pickled pepper
and I wanted to delete up to the fifth p to obtain
pickled pepper
What commands would I be able to use to do this?
You can give motions counts even within d:
d4tp
Using visual mode to select and ; to move to next occurrence makes it easier than counting.
vtp;;;x

I would like to copy n more number of lines in a file. At the moment, I am doing this indirectly: From current line x, I use V<x+n>ggy where <x+n> is substituted with the actual sum.
Is there a way to copy directly n more lines from current line?
You don't need to go into visual mode (the V) for that. The normal mode yy command already takes a [count], but that includes the current line. So for n more lines, you need to pass a [count] of n + 1. Example: Yank current and 2 more lines (total 3): 3yy.
If you don't want to do the arithmetic, you can also use the :yank Ex command. The range there is specified as you want: current (.) until current plus n (.+n). Example: :.,.+2yank
Based on your preference to visual mode, and using gg instead of G to move to a line, it appears as if you're still new to Vim. Learn how to look up commands and navigate the built-in :help; it is comprehensive and offers many tips. You won't learn Vim as fast as other editors, but if you commit to continuous learning, it'll prove a very powerful and efficient editor.
Okay, I found the solution myself while playing around. n more lines can be simply copied by using: Vn+y
Let's say we're currently in this line of code:
readonly L|a|zy<ICountryRepository> countryRepo;
and the cursor is in the position of letter "a", as shown in the code between two "|" symbols.
Now I want to move my cursor to the letter y of the word countryRepo, how can I do that using the minimum key strokes?
(Currently I'm using the key sequence of fyfyfyfy in normal mode ... Kind of stupid)
If you know that it's the 4th y, you can do
4fy
If you know it's the last y in the line, you can do
$Fy
If you don't know at which position it is, you can still do
fy;;;
In this case, I would use
W
to move to countryRepo, followed by
fy
I can think of:
4fy
But you should only do this if you are some strange robot.
/co<cr>fy
Which is one character shorter than your solution, but more easy..
Wfy
Go one WORD forward and then find y.
f>fy
Something like this I would do. Depends on what popups in my mind.
You should look into the easymotion plugin, which helps with arbitrary movements.
EDIT:
easymotion is rather worthless here, it is more useful for jumping to targets further away.
If you have vim-easymotion, https://github.com/Lokaltog/vim-easymotion
You can do <leader><leader>t and then search for letter y. It's not that fast for the letters on the same line though. The real advantage is when you jump in the entire file.
I would do
tR;
or
WtR
or maybe
Wfy
Use EasyMotion.
In your case, <Leader><Leader>e then a corresponding keypress (in this case b) will bring your cursor onto the second y. Personally I use <Leader> as the easymotion trigger so it is only 3 keystrokes for me. The main advantage is you do not need to guess or calculate.
use / for search, then type your word and press Enter
however, if you want to jump to next word, just press n
Let's say I've typed "abcdefg", with the cursor at the end. I want to delete back to the c, so that I only have "abc" left.
Is there a command like d that includes the current character? I know I could do dTcx, but the x feels like a work-around and I suppose there's a better solution.
No. Backward motions always start on the left of the current character for c, y and d which is somehow logical but also unnerving.
The only "clean" solutions I could think of either imply moving to the char after c first and then do a forward delete:
Tcde
or using visual mode:
vTcd
v3hd
But, given your sample and assuming you are entering normal mode just for that correction, the whole thing sounds extremely wasteful to me.
What about staying in insert mode and simply doing ←←←←?
try this:
TcD
this will leave abc for your example... well if the abcdefg is the last word of the line.
if it is not the last word in that line, you may do:
ldTc
or golfing, do it within 3 key-stroke:
3Xx or l4X
See this answer to a similar question : there is a setting to be allowed to go beyond the end of the line
From the doc :
Virtual editing means that the cursor can be positioned where there is
no actual character. This can be halfway into a tab or beyond the end
of the line. Useful for selecting a rectangle in Visual mode and
editing a table.
"onemore" is not the same, it will only allow moving the cursor just
after the last character of the line. This makes some commands more
consistent. Previously the cursor was always past the end of the line
if the line was empty. But it is far from Vi compatible. It may also
break some plugins or Vim scripts. For example because |l| can move
the cursor after the last character. Use with care!
Using the $ command will move to the last character in the line, not
past it. This may actually move the cursor to the left!
The g$ command will move to the end of the screen line.
It doesn't make sense to combine "all" with "onemore", but you will
not get a warning for it.
In short, you could try :set virtualedit=onemore, and see if your environment is stable or not with it.
Use d?c
That will start d mode, search back to 'c' and then delete up to your cursor position.
Edit: nope, that does not include current position...
I may be misunderstanding your request, but does 3hd$ do it?
I would use vFdd in this example. I think it's nicer than the other solutions since the command explicitly shows what to delete. It includes the current character and the specified character when deleting.
v: enter visual mode (mark text)
F: find/goto character backwards
d: the character "d" that will be included for removal.
d: delete command
Since it is visual mode, the cursor can also be moved before executing the actual removal d. This makes the command powerful even for deleting up to a non unique character by first marking a special character close to the character and then adjusting the position.
For example if I have some code like:
foo = bar("abc", "def", true, callback);
Is there a nice command to move true to the 1st or 2nd position leaving the commas intact?
P.S as a bonus my friend want to know if this works in Emacs too.
In Vim if you place the cursor at the start of the first word and do dWWP then it will have the desired effect. Here is a breakdown:
dW delete the current word, including the comma and the following whitespace
W move to the start of the next word
P insert the deleted text before the cursor
This will work if there are further parameters after the pair to be swapped - it will need to be modified if there are only two parameters or you want to swap the last two parameters, since it will paste the text after the closing bracket.
Alternatively you could use a regex substitution:
:%s/(\([^,]\+\),\s*\([^,)]\+\)/(\2, \1/
This will find the first two arguments after the open bracket and swap them.
update:
A search of vim.org found the swap parameters plugin, which should do exactly what you want and can handle situations that either of the above methods cannot.
I don't know the answer for vi, but in Emacs, transpose-sexps (C-M-t) will swap two arguments either side of the cursor. Actually transpose-words (M-t) was my first guess, but that leaves the quotes behind.
You need a transpose emacs command. But its limited to not guessing that its transposing in lists, it only considers text (it can't guess the 1st, 2nd word of list). Try this.
Keep your cursor at after comma of true. Use M-x transpose-words. By default it will transpose with next word from the point. Shortcut is M-t.
You can use C-u 2 M-t for transpose with next second word.
Now coming to your question. If you want to move true, to backward 1 word, use C-u -1 M-t, and for backward 2 words C-u -2 M-t.
Am not a VIM guy. So sorry bout that.
If you want to do this as a refactoring, not just as text manipulation, I'd suggest looking into Xrefactory, a refactoring tool for Emacsen (free for C/Java, commercial for C++).
Transposing previous (Ctrl-t p) and next (Ctrl-t n) argument ... add the
following into your .vimrc file:
map <C-t>p ?,\\|(<CR>wd/,\\|)<CR>?,\\|(<CR>"_dw?,\\|(<CR>a, <C-c>?,<CR>P/,<CR>w
map <C-t>n ?,\\|(<CR>wv/,<CR>d"_dw/\\,\\|)<CR>i, <C-r>"<C-c>?,<CR>?,\\|(<CR>w
My previous question seems to be a bit ambiguous, I will rephrase it:
I have a file like this:
copythis abc
replacethis1 xyz
qwerty replacethis2
hasfshd replacethis3 fslfs
And so on...
NOTE: replacethis1, replacethis2, replacethis3, ... could be any words
How do I replace "replacethis1","replacethis2","replacethis3",.. word by "copythis" word by using minimum vim commands.
One way I can do is by these steps:
delete "replacethis1","replacethis2","replacethis3",.. by using 'dw'
copy "copythis" using 'yw'
move cursor to where "replacethis1" was and do 'p'; move cursor to where "replacethis2" was and do 'p' and so on...
Is there a better way to do this in VIM (using less number of vim commands)?
Since you changed your question, I'd do it this way:
Move to the first "replacethis1" and type cw (change word), then type "copythis" manually.
Move to the next "replacethis", hit . (repeat last operation)
Move to the next "replacethis", hit .,
and so on, and so on.
If "copythis" is a small word, I think this is the best solution.
The digit needs to be included, and there could be more than one instance per line:
:%s/replacethis\d/copythis/g
Given that "replacethis[1-3]" can be arbitrary unrelated words, the quickest/simplest way to do this globally would be:
:%s/replacethis1\|replacethis2\|replacethis3/copythis/g
(Note that you need to use \| to get the pipes to function as "or". Otherwise, vim will look for the literal | character.)
I've been struggling with this for a long time too, I think I just worked out the cleanest way:
Use whichever command is cleanest to put copythis into register r:
/copythis
"rye
Then go to the replacement and replace it with the contents of r:
/replacethis
cw<CTRL-R>r<ESC>
Then you can just n.n.n.n.n.n.n. for the rest of them, or if they're wildly different just go to the beginning of each and hit .
The key is replacing and pasting in one step so you can use . later.
:%s/copythis/replacethis/g
To replace all occurrences of copythis with replacethis. Or you can specify a range of line numbers like:
:8,10 s/copythis/replacethis/g
Note, the /g on the end will tell it to replace all occurrences. If you leave that off it will just do the first one.
create this mapping:
:map z cwcopythis^[
( ^[ is the escape character, you can type it in vim using Ctrl+V Ctrl+[ )
go to each word you want to replace and press z
if u need to do essentially the same action multiple times - swap 1st word of one line with second word of the next line, I say you could record a macro and call it whenever you need to
Have you tried string replacement?
%s/replacethis/copythis
A host of other parameters are possible to fine-tune the replacement. Dive into the Vim help for more details. Some more examples here.
You can remap e.g. the m key in normal mode to delete the word under the cursor and paste the buffer: :nnoremap m "_diwP.
Then you can just copy the desired word, move the cursor anywhere onto the to-be-replaced word and type m.
EDIT: Mapping to m is a bad idea since it is used to mark locations. But you can use e.g. ; anyway.
