I have a fresh vimrc with the following lines:
let mapleader = " "
nnoremap <leader>ft <C-w>v :Ex<CR>
If I open a file that exists on disk already and use the command <leader>ft the desired action will happen and a new window with netrw pops up.
However if I create a new file with vim on the command line i.e. vim mynewfile.txt and use the mapping, a new window is created by is fails to register the second part of the mapping.
Does anyone know if I need to change the mapping somehow to get this to work on new files or whether this is feature/bug in vim?

I was smart enough to run the dG command in vim and instead of simply quitting my muscle memory put in a :wq.
Is there any way to restore the file?
d<motion> cuts the text covered by <motion> into the unnamed register, ". Assuming you have a relatively "normal" setup, Vim should have written the content of that register to ~/.viminfo when you did :wq. If so, you should be able to edit the same file and put the content of that register back into the buffer.
Edit your file in a new Vim session:
$ vim filename
The buffer should be empty.
Inspect the content of every register with :registers to see if it is still stored. If you didn't use Vim in the mean time, register " should have it.
If it is there, do the following, starting from normal mode:
v " start visual mode
"<name of register>p " put from register <name of register>
Recently I've been using netrw. I've put these four lines on my .vimrc:
let g:netrw_banner = 0
let g:netrw_liststyle = 3
let g:netrw_winsize = 25
map <C-n> :Lexplore <CR>
And I can easily toggle Lexplore and browse through the files to edit them. In this mode when I press Enter on any file on left hand side Netrw, it replaces the file in the right hand side window with new file; exactly what I want.
Problems start when I want to preview a file with "p" command on netrw or create a new file with "%" command. In former case (Preview) it split to the new window but I want it again to replace the file in right hand side window just like when I press Enter to to edit the file. And in latter case (creating a new file) it replaces the Lexplore (Netrw in the left hand side) instead of replacing the file on the right hand side window.
Is there any way that I can fix these issues? I've tried a lot of Netrw commands but nothing gives me what I want.
The "p" netrw command is mostly just pedit. So, assuming you don't already have a preview window, just press <cr> atop the file you want to preview and then :set pvw. That will make the window holding the file the preview window.
The second issue concerns "%" to create a new file. I'll think this over, but I think perhaps the better behavior is as you suggest -- keep the Lexplore window but open the new file in the editing window.
Please try version 171e of netrw which you can find at my website.
I believe this is related to a bug in vim. Once you use :Lexplore it apparently changes the g:netrw_chgwin option permanently, so whenever you try to pres <CR> in any netrw window, it will always open in a new window.
I am using linux.
In terminal I can type
vim sample
A vim window for the file 'sample' opens
Here any change can be saved with :w
But I want to open a new vim file having no name and save it with the name sampleName using
:w sampleName
But I am unable to do so.
Typing only vim in terminal gives me a window with about and copyright information
I am not using gvim but vim
You should be able to just run vim with no arguments. It will open vim by itself. To save it to a file, execute the command: :w <new file name>
Issue the Command, :enew and Also Learn about How Vim Manages File Editing
I would recommend reading up on file and buffer usage in Vim in the help file, usr_22.txt.
As architrex has indicated, by default, if one does not have a file(s) listed in the argument list when starting Vim, a new buffer is created. See :help starting.
If you started vim with one file in the file argument list like you described, vim sample, a common way to work with an empty buffer is to issue the :enew command (typically after you would have written changes to the file named, sample, :w).
We can see the new buffer here:
Once one is done modifying the new buffer, you can issue the write command, :w sampleName, with the expected result of writing the file.
Vim's use of buffers is intuitive and you will become more skillful as you use it.
When I started using Vim, I leveraged using NETRW which is a seeded file navigation plugin with Vim for file creation (and placing those new files in buffers).
What follows is one way to leverage NETRW to do this.
If you have already started Vim, I would type :Exp or :e . which are ex commands which will start the file explorer which is a feature of the seeded file navigation plugin, NETRW.
One could start Vim:
Start the file explorer for NETRW:
I would then use the file explorer to navigate to the desired file to create a new file you wish to edit (k is up, j is down, enter key means select).
Next, I would type,%, once I have navigated to the desired location.
You will be notified to "Enter filename". Just enter "sampleName" and press enter.
Go into edit mode (e.g. i) and start typing.
NETRW is a robust file navigation tool. Creating files in the file locations desired is an essential skill to have to utilize Vim well.
You could also read the help files concerning NETRW (e.g. the ex command, :help netrw).
Vim is so awesome. For example, you have a file, called 'test0.html', stored in a folder.
In the same folder, you store the folder 'test' with the files test1.html, and test2.html.
Then you put in test0.html the following content:
include('test/test1.html');
include('test/test2.html');
In vim, you put the cursor on the filenames. You open the files under the corsor with the keys gf. Thats why Vim is so awesome.
I would like to open in a new tab. That's possible with the keys gF.
But what if you want to stay in the same file, but open the file in a background tab, like Chrome does?
So I'm mapping the key.
noremap gf <c-w>gF<c-PageDown>
So, when my cursor is on test1.html, it open with the key gf in a background tab. Wonderful, now I'm a satisfied man.
Then I want to open test2.html under cursor.
Vim jumps to the tab of test1.html, instead stay on test0.html
When I tried to debug this weird behaviour, by only mapping gf to gF, and then do manual CTRL+pagedown, I get the expected behaviour.
My guess is that Vim is much faster with executing the command before he opens the new tab (gF), and so I get to the last tab from the first tab.
Am I correct in my guess explaination?
<c-PageDown> or more commonly used gT will got to the previous tab. <c-w>gF on the other hand will open the file under the cursor in a new tab. That tab will be last tab. So doing a gT will not always make you go back to the previous tab.
You can change your mapping to go back to the previous tab like so:
nnoremap gf :execute "normal! \<lt>c-w>gF" . tabpagenr() . "gt"<cr>
However I would personally suggest you avoid using tabs in such a manner and use buffers instead.
noremap gf :tabe<cfile><CR><c-PageUp>
This is even better. When the file doesn't exist, Vim will create a new one.
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.
