Let's say I have got a line of text like this
Hello World "How are you" World
Now, i want to know, if there's a way to select everything outside the quotes, at once? So, I am expecting something like this where the bolded text is the selection
Hello World "How are you" World
I know it is possible but i am not able to find a way to get this done.
I am thinking of doing something like select both parts individually and join them somehow.
My goal in this is to be able to create a motion that can delete everything except the stuff between " or ' as a operator pending motion. So, the operation can be Delete, Yank or Cut/Change. So, is there any other way to solve the same issue?
That is not possible. In Vim there can only be one selection at once, although there exists a plugin multiselect that claims to do what you want. I have never tried it however.
Place cursor between double quotes, then
yi" # Yank text between double quotes
dd # Delete line
"0p # Paste register 0
Should do the trick.
Similar to #Jens answer:
yi" # Yank text between double quotes
V # Select line
p # Paste yanked text

In Vim, this has been happening to me and I'm wondering the best way to handle it. Example:
something(|)something, else // pipe is the cursor location
I'd like to end up with this:
something(something, else)
I'd also like to be able to do this:
something(something) else _// in case I only want the first word
Assuming you are in insert mode:
" first example
<Del><S-Right><S-Right><S-Right>)
and:
" second example
<Del><S-Right><Del>)
Assuming you are in normal mode, with the cursor on the closing parenthesis:
" first example
x$p
and:
" second example
xeplx
I assume the pair of paranthesis has no space in between so that it looks like ()word, another-word etc etc. Then
d EEp
changes it into (word, another-word) etc etc.
The d initiates a delete. The following space tells vim how much you want to delete: one character (this is the )). An E jumps over a word. So, the double EE jumps over two words. With the final p you insert (paste) what you have deleted (that is the )).
In Vim, let's say I want to replace the contents of one String with the content of another.
Original input
var1 = "January"
var2 = "February"
Desired output
var1 = "January"
var2 = "January"
What I would usually do is:
Move cursor to line 1
y i " (yank inner quotes)
Move cursor to the destination quote in line 2
v i " p (visual select inner quotes, paste)
While this works well, I generally try to avoid visual mode when possible, so I am not completely satisfied with my step 4 (v i " p).
Is there any way to specify a "destination paste area" without using Visual mode? I suspect it might be something chained to g, but I can't think of anything.
There are many ways of doing this however using visual mode is the easiest.
Use the black hole register to delete the content then paste. e.g. "_di"P
Do ci"<c-r>0. <c-r> inserts the contents of a register
Simply paste and then move over a character and delete the old text. e.g pldt"
However visual mode still has my vote. I find that the concerns most people have is that using visual mode + paste is that the default register is swap with the selected text and it doesn't repeat well. Good news everybody! The 0 register always stores the last yank. The bad news is visual mode still doesn't repeat well. Take a look at this vimcast episode, Pasting from Visual mode, for more information. It mentions a few plugin that help with this.
I need this so often, I wrote a plugin to simplify and allow maximum speed: ReplaceWithRegister.
This plugin offers a two-in-one gr command that replaces text covered by a {motion} / text object, entire line(s) or the current selection with the contents of a register; the old text is deleted into the black-hole register, i.e. it's gone. It transparently handles many corner cases and allows for a quick repeat via the standard . command. Should you not like it, its page has links to alternatives.
It's not particularly pretty, but here goes:
Go to line one and yi"
Move to line two
Type "_di"hp
That deletes what's in the quotes, but sends the deleted text to a black hole register. Then it moves the cursor back one, and pastes what you yanked from line one.
All in all, you can start on the first line and type yi"j"_di"hp. Why is it that people find vim intimidating? ;)
Alternatively, yank the first line as normal, then drop to line two and type ci"<Ctrl+p> and select the previously yanked text from the menu.
Excerpt from my .vimrc:
" Delete to 'black hole' register
nnoremap <leader>d "_d
vnoremap <leader>d "_d
So, you just need to \di"P as your last step (assuming you use \ as a <leader>).
There is a plugin that addresses this problem precisely. It was presumably born out of the same feeling you're feeling, namely that Visual mode often feels less than ideal to advanced Vim users.
operator-replace – Operator to replace text with register content
With operator-replace installed the replacing goes like this.
Yank the word inside the quotes.
yi"
Move to the target line
j
Replace inside the quotes with the yanked text. (I've set up gr as the replace operator: :map gr <Plug>(operator-replace). Pick your own mapping.)
gri"
Check it out! This is part of the truly excellent textobj/operator frameworks. I couldn't work without them.
Let's say I have this text:
something "something else"
something here "just another quoted block"
I want to substitute "something else" with "just another quoted block", so I do:
/quot<enter> (to jump to second quoted block searching for the string "quot")
yi" (to yank inner text for current quoted block)
?else<enter> (to jump back to the first quoted block wich contains "else")
vi" (to visually select the quoted block)
p (to paste yanked text)
This works, but I would like to know if the two last steps can be replaced by a single one, to avoid visual mode. I know it's not a huge gain keystroke-wise, but I think that the Vim philosophy would encourage what I'm trying to do, and every time I do this my mind keeps asking for this command. :-P
What I tried so far:
r (replace) replaces just one character
c (change) throws me into Insert mode and does not let me paste the text.
"_di"P
Delete inside quotes to the blackhole register; paste last yanked before cursor.
Or
ci"<Ctrl-R>0<ESC>
Change inside quotes to retrieve last yank; leave insert mode.
With my ReplaceWithRegister plugin, the last two steps would be gri". It also offers grr (replace current / [count] lines); though it only saves a little typing, I find this indispensable.
Key stroke wise, j$yi"k then vi"p is actually probably the fastest. However, if you absolutely must go into insert mode you can j$yi"k then "_ci"<C-r>" or ci"<C-r>0. The :help i_CTRL-R operator allows you to put the contents of a register into insert mode.
I usually try to keep it simple, using what I feel is more intuitive with every day commands:
j
yi"
k
ci"
<ESC>
p
Say I have the following style of lines in a text file:
"12" "34" "some text "
"56" "78" "some more text"
.
.
.
etc.
I want to be able to remove the quotes surrounding the first two columns. What is the best way to do this with Vim (I'm currently using gVim)?
I figured out how to at least delete the beginning quote of each line by using visual mode and then enter the command '<,'>s!^"!!
I'm wondering if there is a way to select an entire column of text (one character going straight down the file... or more than 1, but in this case I would only want one). If it is possible, then would you be able to apply the x command (delete the character) to the entire column.
There could be better ways to do it. I'm looking for any suggestions.
Update
Just and FYI, I combined a couple of the suggestions. My _vimrc file now has the following line in it:
let #q=':%s/"\([0-9]*\)"/\1/g^M'
(Note: THE ^M is CTRLQ + Enter to emulate pressing the Enter key after running the command)
Now I can use a macro via #q to remove all of the quotes from both number columns in the file.
use visual block commands:
start mode with Ctrl-v
specify a motion, e.g. G (to the end of the file),
or use up / down keys
for the selected block specify an action, e.g. 'd' for delete
For more see
:h visual-mode
Control-V is used for block select. That would let you select things in the same character column.
It seems like you want to remove the quotes around the numbers. For that use,
:%s/"\([0-9]*\)"/\1/g
Here is a list of what patterns you can do with vim.
There is one more (sort of ugly) form that will restrict to 4 replacements per line.
:%s/^\( *\)"\([ 0-9]*\)"\([ 0-9]*\)"\([ 0-9]*\)"/\1\2\3\4/g
And, if you have sed handy, you can try these from the shell too.
head -4 filename.txt | sed 's/pattern/replacement/g'
that will try your command on the first 4 lines of the file.
Say if you want to delete all columns but the first one, the simple and easy way is to input this in Vim:
:%!awk '{print $1}'
Or you want all columns but the first one, you can also do this:
:%!awk '{$1="";$0=$0;$1=$1;print}'
Indeed it requires external tool to accomplish the quest, but awk is installed in Linux and Mac by default, and I think folks with no UNIX-like system experience rarely use Vim in Windows, otherwise you probably known how to get a Windows version of awk.
Although this case was pretty simple to fix with a regex, if you want to do something even a bit more advanced I also recommend recording a macro like Bryan Ward. Also macros come easier to me than remembering which characters need to be escaped in vim's regexes. And macros are nice because you can see your changes take place immediately and work on your line transformation in smaller bits at a time.
So in your case you would have pressed qw to start recording a macro in register w (you can of course use any letter you want). I usually start my macros with a ^ to move to the start of the line so the macro doesn't rely on the location of the cursor. Then you could do a f" to jump to the first ", x to delete it, f" to jump to the next " and x to delete that too. Then q to finish recording.
Instead of making your macro end on the next line I actually as late as today figured out you can just V (visually line select) all lines you want to apply your macro to and execute :normal #w which applies your macro in register w to each visually selected line.
See column editing in vim. It describes column insert, but basically it should work in the same way for removing.
You could also create a macro (q) that deletes the quotes and then drops down to the next line. Then you can run it a bunch of times by telling vi how many times to execute it. So if you store the macro to say the letter m, then you can run 100#m and it will delete the quotes for 100 lines. For some more information on macros:
http://vim.wikia.com/wiki/Macros
The other solutions are good. You can also try...
:1,$s/^"\(\w\+\)"/\1/gc
For more Vim regex help also see http://vim.wikia.com/wiki/Search_patterns.
Start visual-block by Ctrl+v.
Jump at the end and select first two columns by pressing: G, EE.
Type: :s/\%V"//g which would result in the following command:
:'<,'>s/\%V"//g
Press Enter and this will remove all " occurrences in the selected block.

Selecting a large amount of text that extends over many screens in an IDE like Eclipse is fairly easy since you can use the mouse, but what is the best way to e.g. select and delete multiscreen blocks of text or write e.g. three large methods out to another file and then delete them for testing purposes in Vim when using it via putty/ssh where you cannot use the mouse?
I can easily yank-to-the-end-of-line or yank-to-the-end-of-code-block but if the text extends over many screens, or has lots of blank lines in it, I feel like my hands are tied in Vim. Any solutions?
And a related question: is there a way to somehow select 40 lines, and then comment them all out (with "#" or "//"), as is common in most IDEs?
Well, first of all, you can set vim to work with the mouse, which would allow you to select text just like you would in Eclipse.
You can also use the Visual selection - v, by default. Once selected, you can yank, cut, etc.
As far as commenting out the block, I usually select it with VISUAL, then do
:'<,'>s/^/# /
Replacing the beginning of each line with a #. (The '< and '> markers are the beginning and and of the visual selection.
Use markers.
Go to the top of the text block you want to delete and enter
ma
anywhere on that line. No need for the colon.
Then go to the end of the block and enter the following:
:'a,.d
Entering ma has set marker a for the character under the cursor.
The command you have entered after moving to the bottom of the text block says "from the line containing the character described by marker a ('a) to the current line (.) delete."
This sort of thing can be used for other things as well.
:'a,.ya b - yank from 'a to current line and put in buffer 'b'
:'a,.ya B - yank from 'a to current line and append to buffer 'b'
:'a,.s/^/#/ - from 'a to current line, substitute '#' for line begin
(i.e. comment out in Perl)
:'s,.s#^#//# - from 'a to current line, substitute '//' for line begin
(i.e. comment out in C++)
N.B. 'a (apostrophe-a) refers to the line containing the character marked by a. ``a(backtick-a) refers to the character marked bya`.
To insert comments select the beginning characters of the lines using CTRL-v (blockwise-visual, not 'v' character wise-visual or 'V' linewise-visual). Then go to insert-mode using 'I', enter your comment-character(s) on the first line (for example '#') and finally escape to normal mode using 'Esc'. Voila!
To remove the comments use blockwise-visual to select the comments and just delete them using 'x'.
Use the visual block command v (or V for whole lines and C-V for rectangular blocks). While in visual block mode, you can use any motion commands including search; I use } frequently to skip to the next blank line. Once the block is marked, you can :w it to a file, delete, yank, or whatever. If you execute a command and the visual block goes away, re-select the same block with gv. See :help visual-change for more.
I think there are language-specific scripts that come with vim that do things like comment out blocks of code in a way that fits your language of choice.
Press V (uppercase V) and then press 40j to select 40 lines and then press d to delete them. Or as #zigdon replied, you can comment them out.
The visual mode is the solution for your main problem. As to commenting out sections of code, there are many plugins for that on vim.org, I am using tComment.vim at the moment.
There is also a neat way to comment out a block without a plugin. Lets say you work in python and # is the comment character. Make a visual block selection of the column you want the hash sign to be in, and type I#ESCAPE. To enter a visual block mode press C-q on windows or C-v on linux.
My block comment technique:
Ctrl+V to start blockwise visual mode.
Make your selection.
With the selection still active, Shift+I. This put you into column insert mode.
Type you comment characters '#' or '//' or whatever.
ESC.
Or you may want to give this script a try...
http://www.vim.org/scripts/script.php?script_id=23
For commenting out lines, I would suggest one of these plugins:
EnhancedCommentify
NERD Commenter
I find myself using NERD more these days, but I've used EnhancedCommentify for years.
If you want to perform an action on a range of lines, and you know the line numbers, you can put the range on the command line. For instance, to delete lines 20 through 200 you can do:
:20,200d
To move lines 20 through 200 to where line 300 is you can use:
:20,200m300
And so on.
Use Shift+V to go in visual mode, then you can select lines and delete / change them.
My usual method for commenting out 40 lines would be to put the cursor on the first line and enter the command:
:.,+40s/^/# /
(For here thru 40 lines forward, substitute start-of-line with hash, space)
Seems a bit longer than some other methods suggested, but I like to do things with the keyboard instead of the mouse.
First answer is currently not quite right?
To comment out selection press ':' and type command
:'<,'>s/^/# /g
('<, '> - will be there automatically)
You should be aware of the normal mode command [count]CTRL-D.
It optionally changes the 'scroll' option from 10 to [count], and then scrolls down that many lines. Pressing CTRL-D again will scroll down that same lines again.
So try entering
V "visual line selection mode
30 "optionally set scroll value to 30
CTRL-D "jump down a screen, repeated as necessary
y " yank your selection
CTRL-U works the same way but scrolls up.
v enters visual block mode, where you can select as if with shift in most common editors, later you can do anything you can normally do with normal commands (substitution :'<,'>s/^/#/ to prepend with a comment, for instance) where '<,'> means the selected visual block instead of all the text.
marks would be the simplest mb where u want to begin and me where u want to end once this is done you can do pretty much anything you want
:'b,'ed
deletes from marker b to marker e
commenting out 40 lines you can do in the visual mode
V40j:s/^/#/
will comment out 40 lines from where u start the sequence
