How to edit the same file in multiple tabs in vim? - vim

I often edit long files in vim that have blocks of code in multiple disparate places in the file that I need to be constantly going back and forth between. Obviously, one way of solving this is to split the window with :split and edit each portion in a different split window, and a :w in either window will save the whole file. This is well and good if you have a large enough screen but sometimes I have to use vim on a low-resolution laptop and I don't want to reduce my screen space further by splitting the window.
In this case, what I'd really like to do is edit the file in multiple tabs, and treat each separate tab exactly like a separate view split. I can sort of mimic this by using :tabopen <the same filename> once I have one copy of the file open, but this is sort of hacky — it doesn't work if I've already made changes to the file because vim thinks I'm just opening the file a second time.
Is there a good way to get the behavior I want with tabs in vim?

The :tab command takes a command as argument.
So you can do this:
:tab split
This will work even if the buffer is modified, and a save in either tab saves the file, updating the saved state in both.

You can use the :tab command:
:[count]tab {cmd}`
Execute {cmd} and when it opens a new window open a new tab page instead. [...] When [count] is omitted the tab page appears after the current one. When [count] is specified the new tab page comes after tab page [count]. Use :0tab cmd to get the new tab page as the first one.
Examples:
:tab split " opens the current buffer in new tab page
:tab help gt " opens tab page with help for "gt"

Quickly search for a specific window in vim based on filename

Many times I end up opening a large number of files in vim using split and vsplit. In such a situation, is there some way by which I can search (by filename) for the window that has a specific file open?
I am looking for functionality similar to tmux find window where we can activate a window by searching for text in that window's scroll buffer. However, in case of of vim, I want to be able to set focus on a window by searching for the filename.
first of all, opening multiple files in split makes file editing easier. However if you open "a large number of files" in split..... I don't know what reason makes you do it. If you want to batch process files, you can considering sed/awk/...
Anyway, you can execute this cmd line in your vim, you give the filename, and this cmd will bring you to the window containing the buf.
:call win_gotoid(bufwinid('YourFileName'))
You can use the buffer command and append the start of your file name - you'll then be able to tab complete the full name. To make tab completion a little more useful (IMO), you can add these settings to your vimrc file:
" first tab completed to the longest common match, or full match,
" second tab completed to show list of all matches,
" third tab starts to cycle through matches
set wildmode=longest,list,full
If you have 3 buffers open - install.sh, readme.md, app.js -
:b in<TAB> will complete the command to :b install.sh - pressing enter will open the buffer containing the install.sh file. If your search term has multiple matches, keep hitting TAB to cycle through all the results.

Vim - open new tab in buffer

I jsut switched from sublime text to vim and I'm trying to replicate sublime's tab view.
I usually have a vertical split opened with :vsp and each split I'd like to open new tabs. To do this I type in bufdo tab split but it opens a new tab over my split and not within the split.
How can I open the tab within the split?
Many thanks
To Open a tab, editing the current file's name you can use %, which acts as a macro for the current file:
:tabe %
To Open a new tab & show the current file's directory:
:Te or :tabe %:h
To move between opened tabs:
gt # Go to next tab
gT # Go to previous tab
In Vim, each edited file corresponds to a buffer. These are displayed in windows. Multiple windows can be split. Multiple such an arrangements of window(s) can be switched to in tab pages (this is a more recent addition).
In this hierarchy, the tab pages are always "above" the windows, so there can only be one single tabline that structures the tab pages. (And it's always between the menu / window title and the windows.)
In Vim, working with window splits is preferred over tab pages. It's recommended to use the latter only to separate different workspaces / projects, etc. Vim is very powerful (and with a long heritage), so you cannot directly take over concepts seen in other editors.

vim:have multiple windows without splitting?

is there any way I can have multiple windows in a terminal based vim, without splitting the window? so I could just switch to the other file by hitting a key ?
if "window" you meant is vim-window, the answer is no.
In vim, a window is a viewport onto a buffer. You can use multiple windows on one
buffer, or several windows on different buffers.
So window is viewport, if you there is no splitting you are watching on single window, no multiple.
I guess what you meant is buffer: A buffer is a file loaded into memory for editing. The original file remains unchanged until you write the buffer to the file.
You can have one window (without splitting) and 10 files(buffers). You could :ls to see the buffer list, and also by command to switch among those buffers/files. display them in single window.
you can get more info about switching files/buffers by:
:h buffer
You could use tabs.
To open a new tab you can use :tabe <file>. After that you can use gt or gT to move to the next or previous tab.
If you are opening a bunch of files from the command line you can use vim -p <files> to open them all in tabs.
Take a look at :h tab-page-commands

turn buffers into tab page in vim

I have a list of buffer in vim, how can I turn all of them into tab page like ones in, say Notepad++?
I know I can use :tabe or something to open new file in tab view, but what if I have opened several buffers in single vim and I want to turn all of them into tab pages?
You can type this command:
:tab ball
It will display all buffers in tabs.
If I understood, you have several buffers in splits and wish every one of them in a separate tab. <Ctrl-w>T will open a buffer in a new tab page removing it from the split.
But tab pages are really not what they are in Notepad++ - separate files. In Vim they're more of a placeholders for splits, so my guess is you'll have a hard time working with them if you mean to just copy your Notepad++'s way of work to Vim.
I don't know your motivations of to turn all buffers into tab pages. Usually, we have many buffers when doing one job, but for tabs, I think it don't have enough spaces to display the tabbars, especially in laptop. Imaging if there were 20 tabs on the top...
So if you want to turn the current buffer into tab page, you can use :tab split. I think it is what you exactly need.

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.

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:
nno \ <Cmd>call To_global_mark()<cr>
fun! To_global_mark()
-tab drop /tmp/useless.md
exe 'normal! `' .. toupper(input("To global mark: "))
