If I open vim with vim . netrw provides me with a nice list of the files and directories in the current directory.
If I open a file using v the file opens in a very narrow split down the left hand side of the screen and the directory listing remains open in a wide split on the right hand side of the screen.
Ideally I'd like it to have the opposite effect. ie. Show the directory listing in a narrow split on the left hand side of the screen and show the file in a wide split on the right hand side of the screen.
Any help much appreciated.
Netrw v153 and later (May 28, 2014) gives you the :Lexplore command, which, by default, opens a directory listing on the left hand side and opens files to the right (by pressing <cr>).
Whilst Jonathan.Brink's answer works perfectly well, simply adding
let g:netrw_altv=1
to .vimrc also seems to do the trick...
See https://superuser.com/questions/1056929/open-file-in-vertical-split-in-vim-netrw/1062063#1062063 for more info.
I'm sure this could be improved upon you can write a custom mapping that target's the netrw filetype.
Stick this in your .vimrc:
" open file vertically to the right
augroup netrw_mappings
autocmd!
autocmd filetype netrw call Netrw_mappings()
augroup END
function! OpenToRight()
:rightbelow vnew
:wincmd p
:normal P
endfunction
function! Netrw_mappings()
noremap V :call OpenToRight()<cr>
endfunction
The only thing is that you need to use V rather than v. For some reason I was unable to override netrw's v command, but using the capital version seems better anyway since it's not overriding a default.

I have a NERDTree setup nicely on my Rails project:
Sometimes, when I do fuzzy finding (Ctrl + P), I would accidentally still be on left tab; when I went to the file, it would replace the nerdtree's left tab. See screenshot below:
Super simple question, but how can I bring up the Nerdtree display back up like the first screnshot?
You should just be able to run :NERDTree again.
Additionally, I have this setting in my .vimrc, to make it less likely I'll delete the NERDTree buffer by accident with I'm compulsively typing :bd
autocmd FileType nerdtree cnoreabbrev <buffer> bd :echo "No you don't"<cr>
Deleting the buffer will permanently put NERDTree in hell (Vim plugins are usually brittle). If you do that, you have to restart Vim.
Also, if you use tabs in Vim, you should get NERDTreeTabs (dead but it works) which keeps NERDTree open / closed / in the same state across all tabs you have open, which is a standard design practice in all editors except Vim. I have a mapping set up to toggle NERDTree:
nnoremap <Leader>nt :NERDTreeTabsToggle<cr>
steal from my my vimrc!
nnoremap <F2> :NERDTreeToggle<CR>
Press F2 twice. The first one will close the NERDTree panel and second one will bring it up again.
F2 can be any key of your choice.
I have NERDTree opened on the default left side, and some vim file on the right side. After I do search with Ag like :Ag! "echo" I get results in the quickfix window. I chose one of the results and by pressing "e" it opens it to the right side and close the quickfix window, but cursor goes to the left side where the NERDTree is located. Is there a way to jump to opened file right after I click "e" and not pressing "ctrl+w" and "l"?
I have the same setup (NERDTree and Ag) and hadn’t noticed this behavior. My workflow is to open a file and then open NERDTree (or vice versa), then Ag at some point. And pressing Enter or e just took me to the line in the file, as expected. The key is that I have some file already open.
I can reproduce the problem you’re seeing by firing up Vim with no file, then opening NERDTree, then running Ag. So a workaround is to have some file open first -- not just an empty Vim with NERDTree open.
The workaround is pretty, uh, workable. It’s already natural to open and close NERDTree frequently. A useful mapping for this is:
nmap <Leader>n :NERDTreeToggle<CR>
An alternative mnemonic would be <Leader>e for Explore. And while we’re at it:
nmap <Leader>g :Ag!<CR>
So the sequence to grep (if you have NERDTree open but no buffer open) is simply ,n,g (assuming your leader is ,).
here is my problem:
i'm using taglist and nerdtree.and set quickfix window displayed no matter if it has context.
and in my vimrc, i set them toggled in a fixed order, so i can get a layout i want.
but when i use C-o, C-i, C-], it will jump to a file, and if i want the features of taglist and nerdtree i should quit it and open it again.
but it will break the layout i want. so i have to quit all and open the file again.
so, is it possible to desable some features in some specific window?
thanks for any help.:)
You can disable certain commands for buffers via :map <buffer>; for sidebar windows like from NERDTree, that's good enough, as they always display the same (scratch) buffer. For example, to disable <C-O> in NERDTree:
:autocmd FileType nerdtree nnoremap <buffer> <C-o> <Nop>
I don't fully understand your question, but another approach (as it is hard to fully control where Vim places new buffer contents) would be to extend your "build your window layout" function from your .vimrc to first clean up any existing NERDTree / TagBar windows, so that you can call it later on (e.g. via a mapping) to "fix up" your layout again.
I opened a files in vim using
gf
command.which opened a file that the current cursor position.
I used
ctrl + ^
is used to toggle between the last two opened files.
But,
How can i go forward and backward opened the files?
:bn & :bp to cycle buffers
To cycle windows I use ctrl+w+w
To cycle opened file :next & :prev
To list opened buffers: :ls
from good old vi :e# reopens previous file ^^ (not using it since ages... well since VIM comes to my systems ^^)
EDIT: a quick test on gvim in windows (set nocp)
map <C-tab> ^[:bn^M
in order to enter escape (^[) and enter (^M) you have to press ctrl+v and then the special char
EDIT 2: a cleaner way to do this is putting this in .vimrc
map <C-tab> <esc>:bn<cr>
but just remember that using mnemonics for the keys depends on some other options (I cannot remember which one).
The best way is IMHO to write a VIM function saving the actual mode, performing switch and then restoring it, then mapping it to in every mode (:[xxx]map commands)
:next to next file
:prev to previous file
Alternatively, you might want to check out any one of the plugins trying to make buffer navigation easier
I myself have reduced it to <leader>bx, x being the number of the buffer.
Selecting the buffer is done via a nice popup list at the bottom.
To get this behavior, you would first install LustyJuggler ( https://github.com/vim-scripts/LustyJuggler ), and then set up the shortcut like so in your vimrc file:
nmap <leader>b :LustyJuggler<CR>
Note that this mapping only works when you are in normal mode.
You can also map the TAB key to quickly cycle through open buffers.
Add the following to your vimrc file:
:nnoremap <Tab> :bnext<CR>
:nnoremap <S-Tab> :bprevious<CR>
In the past, I have used Vim as a note taking platform by creating an index.txt file with a list of tags using the Vim help file format and then creating a bunch of text files that have the normal *Help_Tag* link syntax so that using CTRL-] on a tag in the index.txt file will jump to the respective tag in an arbitrary notes text file. You need to do :helptags dir to generate the tags for the directory (where dir is the path to the notes directory).
What I am looking for is a simple way to be on the left split window and open the tag under the cursor in the right split window. Something like CTRL-W v but for tag jumping and using the already open vertical split window.
The problem is if you do CTRL-] it will open the tag in the left pane and if you do CTRL-W CTRL-] it creates a horizontally split window in the left pane.
There must be a way to do this that I'm overlooking.
map <A-]> :vsp<CR>:exec("tag ".expand("<cword>")) " Open the definition in a new vsplit
Probably the easiset would be an autocommand local mapping
au FileType index.txt nnoremap <buffer> <cr>
\ :vert belowright split
\ |tag <c-r><c-w>
\ |vert resize 130<cr>
Note I use return
Try this mapping:
nmap <buffer> <C-]> :let word=expand("<cword>")<CR><C-W>l:exe "tag" word<CR>
It stores the word under the cursor in the variable word, then swaps the window and goes to the tag with that name. The <buffer> bit makes this mapping only apply to the current buffer.
If you're using headings as note titles, you could use Vim VOoM, which automatically outlines based on sytax and allows for easy navigation with the standard navigation keys.
Vim VOoM also works with foldmarkers, like in the example screenshot.
