How to switch to previous window in another tabpage quickly? - vim

I really like the Ctrl-O and Ctrl-I to jump backward and forward.
If I open fileA, then use :tabe fileB to open another file in a new tabpage.
In the 2nd tabpage, I type Ctrl-O to jump back to the previous location.
Vim simply shows fileA in current window instead of switching to the 1st tabpage.
Now I have two tabpages display the same files. It is not I want.
I can use :drop fileA, but I need to provide full name. It's not good enough.
Is there some good way to switch between windows cross tabpages?

Yes, the switchbuf setting:
set switchbuf=useopen,usetab
I know you know where to get more info on the possible values. ;-)
By the way, along with set hidden, this is the key to using buffers and windows and tabs efficiently in Vim.

vim >> rotate through all buffers opened in target split

Am used to IDE style tab'd panels and am hitting some arggghh inducing scenarios with vim when trying to replicate this functionality using buffers and splits.
I have the following relevant .vimrc settings:
set hidden
set switchbuf=useopen,usetab
Now, let's say I open up 4 buffers, split vertically and then horizontally so that 1 buffer displays on the left and 2 buffers display stacked on the right. The 4th buffer is hidden (opened on the left split).
With the cursor in the left split, using :bnext and :bprevious rotates through all buffers in the left split; that's not desirable as I really have no use for seeing the same file contents in 2 different splits (is there a way to opt-in to the vim cloned buffer affect?). Using :sbnext and :sbprevious works great for visible buffers, but as soon as a hidden buffer is encountered then it opens up in a new split thus wreaking havoc on my layout. The problem gets worse when working with 10+ buffers.
Ideally I'd like to rotate through all buffers visible and hidden within a given split (i.e. where the buffers were opened).
Suggestions appreciated.
p.s. am trying out vim ctrl-space plugin now, quite good but does not address above issue.
Thanks
Why rotate through the buffers when you can go directly to the one you want via :buffer command?
:b foo
:b take either a buffer number or a partial filename (with globs too!). I recommend the partial filename approach. You can also use tab completion to distinguish between ambiguous partial filenames.
You can use :sbuffer (:sb for short) the same way but to open a split instead.
For more help see:
:h :b
:h :sb
The basic navigation unit is the buffer. Windows and tab pages are abstractions built on top of buffers that introduce their own good and bad idiosyncrasies and, most of the time, don't play well with traditional buffers.
You are having troubles because you are trying to apply buffer commands to a window-centered workflow.
As soon as you split your workspace in more than one window you are bound to use window commands for navigation and tab-navigation becomes your standard as soon as you use tab pages. As you noticed, not only is it hard (impossible, AFAIK) to make buffer-navigation window/tab-aware but the alternative techniques actually lack quite a bit in terms of power.
The 4th buffer is hidden (opened on the left split).
That's your first problem: that 4th buffer is hidden and thus transient. It is not opened in any window and could be displayed in any window. You can choose to display a specific buffer in a specific window but you can't really "pin" it to that window.
With the cursor in the left split, using :bnext and :bprevious rotates through all buffers in the left split; that's not desirable as I really have no use for seeing the same file contents in 2 different splits (is there a way to opt-in to the vim cloned buffer affect?).
Again, you are using buffer commands that don't care at all about windows and tab pages.
Using :sbnext and :sbprevious works great for visible buffers, but as soon as a hidden buffer is encountered then it opens up in a new split thus wreaking havoc on my layout.
Again, the wrong tool for the job.
It is possible to keep as many window-local argument lists as you have windows and use those lists with :next and :previous, though, but that would require quite a bit of focus and forethinking. Maybe there's a plugin for that? Anyway:
Create your layout:
:vs|sp
Go back to the large window on the left:
<C-w>w
Put two files in the local argument list:
:arglocal aaa.txt bbb.txt
Move to the next window, edit your local argument list and repeat:
<C-w>w
:arglocal ccc.txt ddd.txt
<C-w>w
:arglocal eee.txt fff.txt
You can now do :next and :previous to switch arguments or <C-^> to switch to the alternate file.
Note that, while you were able to "force" somehow your buffers to specific windows, you are now seriously limited in your ability to navigate around and you now have to deal with a multi-dimensional construction that's rather fragile and requires to too many braincells.
You should consider working with Vim and not against it by using straight buffers as much as possible.
I'm using vim dwm plugin, and it is working very well for my workflow. I'm used to open a lot of buffers in the same window. With this plugin I can manage all of them with easy. I'm using vim-ctrlspace plugin too, and this two plugins are wonderful working together. Well, that's it. I hope this help!

Gvim: Move tab to new window

The opposite question seems to be asked a lot: how to move a window into a new tab in an existing window. What I'm hoping is that a tab that I have open in gvim can be moved out into its own window or into another existing window.
Is this possible?
Thanks!
Same Vim instance
If that tab shows just a single window, you just have to note its buffer number (e.g. via :ls or :echo bufnr(''), or by including it in the statusline), and then close the tab via :close (:set hidden helps with modified buffers), then going to the target tab / window, and re-opening the buffer there via :buf N or :sbuf N.
If you need to support multiple windows in a tab page, you'd have to write a custom command / mapping that first remembers the buffers, and then applies the above steps for all of them.
Different Vim instances
Edit: The above is for movement within a single Vim instance. If you want to move a buffer to another GVIM instance, you first have to :bdelete it in the current Vim, to avoid swap file messages. Launching in new instances is easy:
:execute 'bdelete | !start gvim' shellescape(expand('%:p'), 1)
This passes the (full absolute) path of the current file to a fresh GVIM.
To move a file to an existing GVIM (you need to know its v:servername), you need to use the remote client-server communication (:help remote.txt), e.g. by sending a similar :drop command via remote_send(), like this:
:execute 'bdelete | call remote_send("GVIM1", ":drop " . ' . string(fnameescape(expand('%:p'))) . '. "\<CR>")'
Here is how you can "move" the current buffer to a second GVim instance:
:!gvim --remote %
:bw
Note that Vim must be built with the +clientserver option.
No, it is not possible.
You cannot move a vim tab into a window, no matter new or existing. Because a vim tab page is a collection of windows. You cannot move a collection of windows into one single window.

Using :Vexplore effectively

So, the :Vexplore command in vim opens a nice little directory browser to the left.
But how do I then open a file from that side-pane into the main window on the right?
One would assume there's a simple mapping for it, but I can't seem to find it.
I think you want o or P
Also, have a look at the documentation, e.g.
:he netrw-p11
It turns out it's just a single line in .vimrc:
let g:netrw_browse_split=4 " Open file in previous buffer
Source: http://vimcasts.org/episodes/the-file-explorer/#comment-45366660
I'm sure what you're looking for is this:
:Vexplore!
This is the same command you would use to navigate to different windows in Vim (like quickfix window, or different split), everything is explained in
:help windows.txt
But to answer to your question directly:
CTRLwCTRLh to move to the left window
CTRLwCTRLl to move to the right window
then Enter to select the file you want to open.
You might want to read :help netrw as well
The latest netrw plugin (up to v153f) now provides the :Lexplore command, which opens an explorer on the right hand side of the vim display. It sets g:netrw_chgwin so edits occur in the window to the right of the netrw window. You can get it from http://www.drchip.org/astronaut/vim/index.html#NETRW .

How to jump back to NERDTree from file in tab?

I usually:
Choose the needed file.
Open it in a tab(t character, by default).
But how I can jump back to NERDTree to open one more file in a tab?
Temporary solution I use now in my .vimrc file:
map <F10> :NERDTree /path/to/root/of/my/project
But it's not very useful to start navigation again and again from the root directory.
Ctrl-ww
This will move between open windows (so you could hop between the NERDTree window, the file you are editing and the help window, for example... just hold down Ctrl and press w twice).
Ctrl+ww cycle though all windows
Ctrl+wh takes you left a window
Ctrl+wj takes you down a window
Ctrl+wk takes you up a window
Ctrl+wl takes you right a window
NERDTree opens up in another window. That split view you're seeing? They're called windows in vim parlance. All the window commands start with CTRL-W. To move from adjacent windows that are left and right of one another, you can change focus to the window to the left of your current window with CTRL-w h, and move focus to the right with CTRL-w l. Likewise, CTRL-w j and CTRL-w k will move you between horizontally split windows (i.e., one window is above the other). There's a lot more you can do with windows as described here.
You can also use the :NERDTreeToggle command to make your tree open and close. I usually bind that do t.
If you use T instead of t there is no need to jump back because the new tab will be opened, but vim's focus will simply remain within NERDTree.
You can focus on a split window using # ctrl-ww.
for example, pressing:
1 ctrl-ww
would focus on the first window, usually being NERDTree.
Since it's not mentioned and it's really helpful:
ctrl-wp
which I memorize as go to the previously selected window.
It works as a there and back command. After having opened a new file from the tree in a new window press ctrl-wp to switch back to the NERDTree and use it again to return to your previous window.
PS: it is worth to mention that ctrl-wp is actually documented as go to the preview window (see: :help preview-window and :help ctrl-w).
It is also the only keystroke which works to switch inside and explore the COC preview documentation window.
ctrl-ww Could be useful when you have limited tabs open. But could get annoying when you have too many tabs open.
I type in :NERDTree again to get the focus back on NERDTree tab instantly wherever my cursor's focus is. Hope that helps
The top answers here mention using T to open a file in a new tab silently, or Ctrl+WW to hop back to nerd-tree window after file is opened normally.
IF WORKING WITH BUFFERS: use go to open a file in a new buffer, silently, meaning your focus will remain on nerd-tree.
Use this to open multiple files fast :)
You can change the tabs by ctrl-pgup and ctrl-pgdown. On that tab you came from the NERDTree is still selected and you can open another tab.
In more recent versions of NERDTree you can use the command :NERDTreeFocus, which will move focus to the NERDTree window.
gt = next Tap
gT = previous Tab
if you want you can enable the mouse support editing ~/.vimrc file.
put set mouse=a
after that you enable files click in NERDTree.

Using Vim's tabs like buffers

I have looked at the ability to use tabs in Vim (with :tabe, :tabnew, etc.) as a replacement for my current practice of having many files open in the same window in hidden buffers.
I would like every distinct file that I have open to always be in its own tab. However, there are some things that get in the way of this. How do I fix these:
When commands like gf and ^] jump to a location in another file, the file opens in a new buffer in the current tab. Is there a way to have all of these sorts of commands open the file in a new tab, or switch to the existing tab with the file if it is already open?
When switching buffers I can use
:b <part of filename><tab>
and it will complete the names of files in existing buffers. <part of filename> can even be the middle of a filename instead of the beginning. Is there an equivalent for switching tabs?
Stop, stop, stop.
This is not how Vim's tabs are designed to be used. In fact, they're misnamed. A better name would be "viewport" or "layout", because that's what a tab is—it's a different layout of windows of all of your existing buffers.
Trying to beat Vim into 1 tab == 1 buffer is an exercise in futility. Vim doesn't know or care and it will not respect it on all commands—in particular, anything that uses the quickfix buffer (:make, :grep, and :helpgrep are the ones that spring to mind) will happily ignore tabs and there's nothing you can do to stop that.
Instead:
:set hidden
If you don't have this set already, then do so. It makes vim work like every other multiple-file editor on the planet. You can have edited buffers that aren't visible in a window somewhere.
Use :bn, :bp, :b #, :b name, and ctrl-6 to switch between buffers. I like ctrl-6 myself (alone it switches to the previously used buffer, or #ctrl-6 switches to buffer number #).
Use :ls to list buffers, or a plugin like MiniBufExpl or BufExplorer.
Bit late to the party here but surprised I didn't see the following in this list:
:tab sball - this opens a new tab for each open buffer.
:help switchbuf - this controls buffer switching behaviour, try :set switchbuf=usetab,newtab. This should mean switching to the existing tab if the buffer is open, or creating a new one if not.
Vim :help window explains the confusion "tabs vs buffers" pretty well.
A buffer is the in-memory text of a file.
A window is a viewport
on a buffer.
A tab page is a collection of windows.
Opening multiple files is achieved in vim with buffers. In other editors (e.g. notepad++) this is done with tabs, so the name tab in vim maybe misleading.
Windows are for the purpose of splitting the workspace and displaying multiple files (buffers) together on one screen. In other editors this could be achieved by opening multiple GUI windows and rearranging them on the desktop.
Finally in this analogy vim's tab pages would correspond to multiple desktops, that is different rearrangements of windows.
As vim help: tab-page explains a tab page can be used, when one wants to temporarily edit a file, but does not want to change anything in the current layout of windows and buffers. In such a case another tab page can be used just for the purpose of editing that particular file.
Of course you have to remember that displaying the same file in many tab pages or windows would result in displaying the same working copy (buffer).
Contrary to some of the other answers here, I say that you can use tabs however you want. vim was designed to be versatile and customizable, rather than forcing you to work according to predefined parameters. We all know how us programmers love to impose our "ethics" on everyone else, so this achievement is certainly a primary feature.
<C-w>gf is the tab equivalent of buffers' gf command. <C-PageUp> and <C-PageDown> will switch between tabs. (In Byobu, these two commands never work for me, but they work outside of Byobu/tmux. Alternatives are gt and gT.) <C-w>T will move the current window to a new tab page.
If you'd prefer that vim use an existing tab if possible, rather than creating a duplicate tab, add :set switchbuf=usetab to your .vimrc file. You can add newtab to the list (:set switchbuf=usetab,newtab) to force QuickFix commands that display compile errors to open in separate tabs. I prefer split instead, which opens the compile errors in a split window.
If you have mouse support enabled with :set mouse=a, you can interact with the tabs by clicking on them. There's also a + button by default that will create a new tab.
For the documentation on tabs, type :help tab-page in normal mode. (After you do that, you can practice moving a window to a tab using <C-w>T.) There's a long list of commands. Some of the window commands have to do with tabs, so you might want to look at that documentation as well via :help windows.
Addition: 2013-12-19
To open multiple files in vim with each file in a separate tab, use vim -p file1 file2 .... If you're like me and always forget to add -p, you can add it at the end, as vim follows the normal command line option parsing rules. Alternatively, you can add a bash alias mapping vim to vim -p.
I ran into the same problem. I wanted tabs to work like buffers and I never quite manage to get them to. The solution that I finally settled on was to make buffers behave like tabs!
Check out the plugin called Mini Buffer Explorer, once installed and configured, you'll be able to work with buffers virtaully the same way as tabs without losing any functionality.
This is an answer for those not familiar with Vim and coming from other text editors (in my case Sublime Text).
I read through all these answers and it still wasn't clear. If you read through them enough things begin to make sense, but it took me hours of going back and forth between questions.
The first thing is, as others have explained:
Tab Pages, sound a lot like tabs, they act like tabs and look a lot like tabs in most other GUI editors, but they're not. I think it's an a bad mental model that was built on in Vim, which unfortunately clouds the extra power that you have within a tab page.
The first description that I understood was from #crenate's answer is that they are the equivalent to multiple desktops. When seen in that regard you'd only ever have a couple of desktops open but have lots of GUI windows open within each one.
I would say they are similar to in other editors/browsers:
Tab groupings
Sublime Text workspaces (i.e. a list of the open files that you have in a project)
When you see them like that you realise the power of them that you can easily group sets of files (buffers) together e.g. your CSS files, your HTML files and your JS files in different tab pages. Which is actually pretty awesome.
Other descriptions that I find confusing
Viewport
This makes no sense to me. A viewport which although it does have a defined dictionary term, I've only heard referring to Vim windows in the :help window doc. Viewport is not a term I've ever heard with regards to editors like Sublime Text, Visual Studio, Atom, Notepad++. In fact I'd never heard about it for Vim until I started to try using tab pages.
If you view tab pages like multiple desktops, then referring to a desktop as a single window seems odd.
Workspaces
This possibly makes more sense, the dictionary definition is:
A memory storage facility for temporary use.
So it's like a place where you store a group of buffers.
I didn't initially sound like Sublime Text's concept of a workspace which is a list of all the files that you have open in your project:
the sublime-workspace file, which contains user specific data, such as the open files and the modifications to each.
However thinking about it more, this does actually agree. If you regard a Vim tab page like a Sublime Text project, then it would seem odd to have just one file open in each project and keep switching between projects. Hence why using a tab page to have open only one file is odd.
Collection of windows
The :help window refers to tab pages this way. Plus numerous other answers use the same concept. However until you get your head around what a vim window is, then that's not much use, like building a castle on sand.
As I referred to above, a vim window is the same as a viewport and quiet excellently explained in this linux.com article:
A really useful feature in Vim is the ability to split the viewable area between one or more files, or just to split the window to view two bits of the same file more easily. The Vim documentation refers to this as a viewport or window, interchangeably.
You may already be familiar with this feature if you've ever used Vim's help feature by using :help topic or pressing the F1 key. When you enter help, Vim splits the viewport and opens the help documentation in the top viewport, leaving your document open in the bottom viewport.
I find it odd that a tab page is referred to as a collection of windows instead of a collection of buffers. But I guess you can have two separate tab pages open each with multiple windows all pointing at the same buffer, at least that's what I understand so far.
You can map commands that normally manipulate buffers to manipulate tabs, as I've done with gf in my .vimrc:
map gf :tabe <cfile><CR>
I'm sure you can do the same with [^
I don't think vim supports this for tabs (yet). I use gt and gT to move to the next and previous tabs, respectively. You can also use Ngt, where N is the tab number. One peeve I have is that, by default, the tab number is not displayed in the tab line. To fix this, I put a couple functions at the end of my .vimrc file (I didn't paste here because it's long and didn't format correctly).
I use buffers like tabs, using the BufExplorer plugin and a few macros:
" CTRL+b opens the buffer list
map <C-b> <esc>:BufExplorer<cr>
" gz in command mode closes the current buffer
map gz :bdelete<cr>
" g[bB] in command mode switch to the next/prev. buffer
map gb :bnext<cr>
map gB :bprev<cr>
With BufExplorer you don't have a tab bar at the top, but on the other hand it saves space on your screen, plus you can have an infinite number of files/buffers open and the buffer list is searchable...
Looking at
:help tabs
it doesn't look like vim wants to work the way you do...
Buffers are shared across tabs, so it doesn't seem possible to lock a given buffer to appear only on a certain tab.
It's a good idea, though.
You could probably get the effect you want by using a terminal that supports tabs, like multi-gnome-terminal, then running vim instances in each terminal tab. Not perfect, though...
If you want buffers to work like tabs, check out the tabline plugin.
That uses a single window, and adds a line on the top to simulate the tabs (just showing the list of buffers). This came out a long time ago when tabs were only supported in GVim but not in the command line vim. Since it is only operating with buffers, everything integrates well with the rest of vim.
relevant:
Vim: can global marks switch tabs instead of the file in the current tab?
maybe useful to solve a little part of OP's problem:

fun! To_global_mark()
-tab drop /tmp/useless.md
exe 'normal! `' .. toupper(input("To global mark: "))
