pageup and pagedown does not work in vim using konsole - linux

I have just recently moved to SLES12 from SLES11
Using vim in SLES11 pageup and page down worked perfectly while SLES12 it is not. (in gvim - it does work)
I am trying several solutions written in others threads like without success :(
map <CTRL-V><CTRL-PAGEUP> :tabp<CR>
map <C-PageUp> :echo "hello"<CR>
map ^[[5^ :echo "hello"<CR>
I think it might related to the fact of the bindkeys of the terminals as one of the threads mention- but I do not find which one is related to pageup/down.
any clue?

This is a problem with the way your terminal is set up.
As you have stated you are using Konsole, you can check the settings by right clicking on an open terminal window and selecting Edit Current Profile:
That should open up another window like:
On this screen select the keyboard option on the left and check your keyboards. For a quick win you can try changing the keybinding or reset to default. If that isn't enough you will need to go into the keybinding and ensure the PgUp is producing the expected code: ^[[5~. Doing so should be fairly straightforward.

Vim windows navigation inside vim inside vim-terminal not working as expected

Vim windows navigation breaks for me once I perform these steps:
from (bash in my case) terminal open vim (8.1) in terminal mode
>vim -c ":term ++curwin"
then from the vim-terminal open vim
>vim
From inside vim, open a new split window
:sp
try navigating
<C-w><C-w>
and it doesn't work
Using Vim as a terminal emulator and Vim again inside of it, I see. Are you trying to create a black hole?
Anyway, if the built-in terminal allowed this it would function as a keyboard trap, effectively making it impossible to move the focus to another (host) Vim window.
It's really a classic case of the host capturing a keystroke and preventing the hosted program to receive it. Pretty much like screen using <C-a> as leader and thus preventing you from incrementing the number under the cursor in Vim.
And just like screen that lets you do <C-a>a to send an actual <C-a> to the hosted program, Vim's built-in terminal lets you do <C-w>. to send an actual <C-w>.
Therefore, you can do <C-w>.<C-w>. to achieve your goal (however misguided it might be).
See :help terminal-typing.

To scroll in gdb window using Termdebug in Vim

I'm using vim since a while to code in c++, and I use the plugin Termdebug to have the gdb window included in vim, with all the commands easily usable etc... my problem is that I can't scroll up or down in the gdb command window and in the output window, because up and down arrows only show precedent and next commands, none of the combo I tried worked (like C-Up or A-Up). I already tried some solutions:
lauching vim with :let g:termdebug_use_prompt = 1, so I can go in normal mode in the termdebug windows. It worked, but the text displayed is ugly and buggy (text which was bold isn't anymore, random line breaks in the middle of lines...).
as How to scroll the gdb window within cgdb? says, using PageUp/PageDown, but my laptop doesn't have these keys. I tried to map new combinations of keys with https://github.com/sezanzeb/key-mapper or by modifying ~/.config/openbox/lxqt-rc.xml, but when I tried them it only wrote "3~" and ";3~" whether in Vim or in Qterminal btw. Edit : tried with another computer with Page Up / Down key, doesn't work.
Using C-w + :C-y, as C-w make it possible to enter vim commands in the gdb window and C-y scroll up in vim. In the vim and the gdb window, it raises an E464 Error, saying the command is ambiguous. Edit : vim commands doesn't seem to work at all in gdb windows, command :go which should move the cursor to the beginning of the file has no effect.
If someone has a solution making it possible to switch between modes in the gdb window, but with a correct display it would be perfect, allowing me to use all my vim maps in the gdb window, however just a solution to scroll would already save me.
Problem solved ! Doing "C-W N" in the gdb and/or in the I/O window switch them to normal mode, making possible the scrolling.

MacVim: Any idea why I can't override the Command button?

I am trying to use the command button in MacVim instead of Ctrl and other buttons.
I tried something like :imap <D-space> <Esc> to override the normal Command-space functionality while in MacVim but it still performs the spotlight.
Any ideas?
In these cases its usually the window manager intercepting the key-stroke before the application ever sees it. There may be an option to turn off certain global key-bindings when a specified app is active but I've been unable to find it on 10.5 - linux window managers have this functionality, as does windows, so I'd expect its hiding somewhere in the OS WM..
The Spotlight shortcut takes precedence over your own shortcut.
To be able to use it in MacVim you must change Spotlight's shortcut in its preferences.
However, the Command key won't work in Terminal.app and won't be sent to remote servers connected by SSH. If you use Vim on a server you won't be able to use it and you will be forced to either create and learn lots of machine-specific mappings or simply use the defaults.
Another possible issue, one I encountered at the beginning, is that shortcuts with multiple modifier keys (like <D-M-something> or <C-S-something>) don't work in MacVim.
Because of that and the number of native shortcuts using these keys you won't have many possibilities.
When I decided to learn Vim (with MacVim), I tried a lot of things to make it (and Vim) more "Mac-like" or "TextMate-like" to no avail.
Instead i suggest you to do things the Vim way. It may seem weird but it's worth it.
In your case, the "Vim way" would be to use mapleader, it's a regular key on your keyboard that is used for custom mappings. The default key is \, if you want to change it (to , for the example, that's my settings but YMMV), add this line to your ~/.vimrc:
let mapleader=","
After that you can create mappings like this:
inoremap <leader><Space> <ESC>

Open vim tab in new (GUI) window?

I'd like to move the current tab into a new (visual/real) window in MacVim.
It's probably difficult, as:
there is nothing in the vim help and only very few - not helpful - hits on google
MacVim does not support it (link, 2009)
So I am wondering if someone has found a way to achieve this?
The closest I think you can come is using mksession
This will have several drawbacks (like, initially the secondary session will open a few more buffers than ultimately desired).
However, it will preserve your mappings, settings, history, window layout (if you had multiple windows inside the current tab, they will all get cloned).
If this idea tickles your fancy, you could look at creating a script that will filter parts out of the session file (which is Yust Another Vim Text Script)
:mksession! $HOME/detach.vim
:tabclose
:silent! !gvim remote --servername Detach -nR +'silent! source H:\detach.vim' +tabonly
save all current windows, mappings, settings (:he mksession)
close the tab we are about to detach
clone the session (detach.vim) into a remote vim
:silent! (try not to talk too much)
!gvim remote --servername Detach; launch a new remote Vim server if it doesn't yet exist, or talk to the existing server named Detach
-nR TODO Fix This is here to avoid the use of swapfiles (because I found no way to suppress the dreaded ATTENTION messages[1]). However, this may be unsafe advice depending on your situation, which is why I also include -R for read-only mode
+'silent! source H:\detach.vim' +tabonly -- In the remote vim, source the session to clone, and keep only the active tab (that was already closed in step 1.)
A little rough around the edges, for sure, but quite close to what you intended, I feel.
If you are comfortable, you can drop the -nR flags and just click through a few annoying swapfile attention messages (keyboard: Q).
[1] :he ATTENTION
Post-scripts:
on windows you might want to use :silent! !start /b gvim .... in case you have terminal windows sticking around
also on windows, you might get annoying behaviour if the resulting gvim window is too small. The :simalt ~x sequence is one hacky way to maximize the window (assuming English UI, because x is the accelerator for Maximize)
as icing on the cake, vim 7.3 has 'persistent undo'. See e.g. :se undofile
I don't think this is possible because, when you open a new instance of (g)vim you don't have access to the undo-history of the previous vim instance. All you can do is (in command mode):
:!gvim %
It will open the current file in a new instance of gvim. At least this is all I could think of. I may be wrong

How do I run a terminal inside of Vim?

I am used to Emacs, but I am trying out Vim to see which one I like better.
One thing that I like about Emacs is the ability to run a terminal inside Emacs. Is this possible inside of Vim? I know that you can execute commands from Vim, but I would like to be able to run a terminal inside of a tab.
Outdated from August 2011
Check out Conque Shell (also on GitHub). Lets you run any interactive program inside vim, not just a shell.
I'm not sure exactly what you're trying to achieve (I've never used Emacs), but you can run commands in Vim by typing:
:! somecommand [ENTER]
And if you want to type in several commands, or play around in a shell for a while, you can always use:
:! bash (or your favourite shell) [ENTER]
Once the command or shell terminates, you'll be given the option to press Enter to return to your editor window
Vim is intentionally lightweight and lacking in the ability to do non-editorish type things, just as running a full-blown shell inside a Vim pane/tab, but as mentioned above there are third-party addons such as vim-shell that allow you to do that sort of thing.
Typically if I want to switch between Vim and my shell (Bash), I just hit CTRL+Z to pause the Vim process, play around in my shell, then type 'fg' when I want to go back to Vim - keeping my editor and my shell nice and separate.
Updated answer (11 years later...):
I would recommend using tmux instead of screen as suggested in the original answer below, if you choose to use that solution.
Vim 8.1 now has a built in terminal that can be opened with the :term command. This provides much more complete integration with the rest of the Vim features.
I would definitely recommend screen for something like this. Vim is a text editor, not a shell.
I would use Ctrl+AS to split the current window horizontally, or in Ubuntu's screen and other patched versions, you can use Ctrl+A|(pipe) to split vertically. Then use Ctrl+ATab (or equivalently on some systems, Ctrl+ACtrl+I which may be easier to type) to switch between the windows. There are other commands to change the size and arrangement of the windows.
Or a less advanced use of screen is just to open multiple full-screen windows and toggle between them. This is what I normally do, I only use the split screen feature occasionally.
The GNU Screen Survival Guide question has a number of good tips if you're unfamiliar with its use.
The way that I get around this is:
pause Vim with Ctrl + Z,
play in the terminal,
then return to exactly where you left with Vim by just typing the command fg.
If enabled in your version of Vim, a terminal can be started with the :term command.
Terminal window support was added to Vim 8. It is an optional feature that can be enabled when compiling Vim with the +terminal feature. If your version of Vim has terminal support, :echo has('terminal') will output "1".
Entering :term will place you in Terminal-Job mode, where you can use the terminal as expected.
Within Terminal-Job mode, pressing Ctrl-W N or Ctrl-\ Ctrl-N switches the mode to Terminal-Normal, which allows the cursor to be moved and commands to be ran similarly to Vim's Normal mode. To switch back to Terminal-Job mode, press i.
Other answers mention similar functionality in Neovim.
:sh then Ctrl+D to get back in (bash)
Update:
You could map Ctrl+D in vim to run :sh, which allows you to toggle between bash and vim quickly.
noremap <C-d> :sh<cr>
The main new feature of Vim 8.1 is support for running a terminal in a Vim window.
:term will open the terminal in another window inside Vim.
:term
Added in Vim 8.1.
Keep in mind that whenever a terminal window is active, most keystrokes will simply be passed to the terminal instead of having their usual functions. Ctrl-W and its subcommands are the main exception. To send a literal ^W input to the terminal, press Ctrl-W .. You can also open the Vim : command line by pressing Ctrl-W :. The other Ctrl-W commands work as normal, so managing windows works the same no matter what type of window is currently selected.
Eventually a native :terminal command was added to vim in 2017.
Here is an excerpt from the :terminal readme:
This feature is for running a terminal emulator in a Vim window. A
job can be started connected to the terminal emulator. For example, to
run a shell:
:term bash
Or to run build command:
:term make myprogram
The job runs asynchronously from Vim, the window will be updated to
show output from the job, also while editing in another window.
This question is rather old, but for those finding it, there's a new possible solution: Neovim contains a full-fledged, first-class terminal emulator, which does exactly what ConqueTerm tried to. Simply run :term <your command here>.
<C-\><C-n> will exit term mode back to normal-mode. If you're like me and prefer that escape still exit term mode, you can add this to your nvimrc:
tnoremap <ESC><ESC> <C-\><C-N>
And then hitting ESC twice will exit terminal mode back to normal-mode, so you can manipulate the buffer that the still-running command is writing to.
Though keep in mind, as nvim is under heavy development at the time I'm posting this answer, another way to exit terminal mode may be added. As Ctrl+\Ctrl+n switches to normal mode from almost any mode, I don't expect that this answer will become wrong, but be aware that if it doesn't work, this answer might be out of date.

I know that I'm not directly answering the question, but I think it's a
good approach. Nobody has mentioned tmux (or at least not as a
standalone answer). Tmux is a terminal multiplexor like screen. Most
stuff can be made in both multiplexors, but afaik tmux it's more easily
to configure. Also tmux right now is being more actively developed than
screen and there's quite a big ecosystem around it, like tools that help
the configuration, ecc.
Also for vim, there's another plugin: ViMUX, that helps a lot in
the interaction between both tools. You can call commands with:
:call VimuxRunCommand("ls")
That command creates a small horizontal split below the current pane vim
is in.
It can also let you run from a prompt in case you don't want to run the
whole command:
<Leader>vp :VimuxPromptCommand<CR>
As it weren't enought, there are at least 6 'platform specific plugins':
vim-vroom: runner for rspec, cucumber and test/unit; vimux support via g:vroom_use_vimux
vimux-ruby-test: a set of commands to easily run ruby tests
vimux-cucumber: run Cucumber Features through Vimux
vim-turbux: Turbo Ruby testing with tmux
vimux-pyutils: A set of functions for vimux that allow to run code blocks in ipython
vimux-nose-test: Run nose tests in vimux
Here is a nice "use case": Tests on demand using Vimux and Turbux with Spork and Guard
Someone already suggested https://github.com/Shougo/vimshell.vim, but they didn't mention why. Consequently, when I came away from this question I wasted a lot of other time trying the other (much higher ranked) options.
Shougo/vimshell is the answer. Here's why:
In addition to being a terminal emulator, VimShell allows you to navigate through terminal output in normal and visual mode. Thus, if a command you run results in output that you'd like to copy and paste using the keyboard only...VimShell covers this.
None of the other options mentioned, including the :terminal command in NeoVim do this. Neovim's :terminal comes close, but falls short in at least the following ways as of 2/18/2017:
Moves the cursor to the end of the buffer, instead of at the last keeping it in the same spot like VimShell does. Huge waste of time.
Doesn't support modifiable = 1 see a discussion on this at Github, so helpful plugins like vim-easymotion can't be used.
Doesn't support the display of line numbers like Vimshell does.
Don't waste time on the other options, including Neovim's :terminal. Go with VimShell.
It's possible to open a new tab with a terminal in vim since 2017 as #fjardon said:
Just type: :terminal. It will open a tab by default above your current tab.
If you want it to open in another place you can try the following options:
:below terminal : open the terminal below current tab.
:below vertical terminal : open the terminal always vertically to the right.
You can play with these until you find what you like. After this you can set a map in your .vimrc configuration file, for me, I use:
nmap <leader>tt :below vertical terminal<CR>
This way I can type <space>tt (space my leader key) to open it quickly.
As a side note:
You can switch between your tabs (terminal and other buffers) with Ctrl+W Ctrl+W.
You can enter an editable mode in your terminal if you want to copy your commands with Ctrl+W N and go to normal terminal mode with i or a.
Cheers!
You might want to take a look at the :sh command (see :help sh in Vim).
Various commands
No, you cannot:

By far, I have tried a lot of solutions mentioned here, what I really wanted is to keep the terminal open while coding a similar experience in VsCode. Then I came across this solution which is working perfectly for me.
Before Installing:
I am using Nvim 0.5 but I think it can work for any version and checked also on vim
I am using macOS Catalina Version 10.15.7
Setup your integrated terminal
Step -1-
Create a script with the name myQuickTerminal.vim or whatever name you want.
Put the following script
"==============================================================================
"
" ▒█▀▀█ █░░█ ░▀░ █▀▀ █░█   ▀▀█▀▀ █▀▀ █▀▀█ █▀▄▀█ ░▀░ █▀▀▄ █▀▀█ █░░
" ▒█░▒█ █░░█ ▀█▀ █░░ █▀▄   ░▒█░░ █▀▀ █▄▄▀ █░▀░█ ▀█▀ █░░█ █▄▄█ █░░
" ░▀▀█▄ ░▀▀▀ ▀▀▀ ▀▀▀ ▀░▀   ░▒█░░ ▀▀▀ ▀░▀▀ ▀░░░▀ ▀▀▀ ▀░░▀ ▀░░▀ ▀▀▀
"
"==============================================================================
" " This is a script that will trigger a terminal quickly than the FloatTerminal
" open new split panes to right and below
"link: https://betterprogramming.pub/setting-up-neovim-for-web-development-in-2020-d800de3efacd
"==============================================================================
set splitright
set splitbelow
" turn terminal to normal mode with escape
tnoremap <Esc> <C-\><C-n>
" start terminal in insert mode
au BufEnter * if &buftype == 'terminal' | :startinsert | endif
" open terminal on ctrl+n
function! OpenTerminal()
split term://zsh
resize 10
endfunction
nnoremap <leader> n :call OpenTerminal()<CR>
NOTE: if you want to run bash instead of zsh for a particular reason then replace zsh with bash.
Step -2-
Lets source it, put this in init.vim for neovim or `.vimrc' for vim
source $HOME/.config/nvim/modules/mySpecialScripts/myQuickTerminal.vim
This will be preloaded ahead as you save and resource it, you can use source $MYVIMRC for quick reloading the init.vim file.
Step -3-
I mapped as you can see in the script n to open a terminal in a new pane, my is the (Space bar) and once I click (space + n) a terminal will be triggered and I will enjoy writing my code while the terminal is opened.
To quit insert mode in the terminal, press Esc.
Now, to switch to the code editor pane, use CTRL+w w. This shortcut can get annoying once you have more than two panels open, so I added the following shortcuts too.
I mapped these too for quick jumping among opened panes, use these
" Better window navigation
nnoremap <C-h> <C-w>h
nnoremap <C-j> <C-w>j
nnoremap <C-k> <C-w>k
nnoremap <C-l> <C-w>l
Optional
If you want your terminal to exit the current buffer with key. you can use
tnoremap <Esc> <C-\><C-n>:q!<CR>
But since I want to switch in between several buffers I use without close the terminal I use instead:
tnoremap <Leader><Esc> <C-\><C-n>:q!<CR>
Final results
Reference:
https://betterprogramming.pub/setting-up-neovim-for-web-development-in-2020-d800de3efacd
Only way I know of is by using vim-shell, a third-party patch.
I use this now, you may can try. VimShell
Split the screen and run command term ++curwin to run the terminal inside the Vim buffer. Following command does both and worked for me:
:bo 10sp | term ++curwin
If you are interested in quick answer, here is it: :vert term. It will split your screen vertically and open up terminal.
Try vterm, which is a pretty much full feature shell inside vim. It is slightly buggy with its history and clear functions, and still in development, but it still is pretty good
Assuming your version of vim supports +term command first, set shell for vim to use in one command (e.g. set=/usr/bin/zsh), and then run the command +term (i.e. bo 15vs +term). you may have to do some additional maneuvering of your windows (i.e. deleting one and rotating), but you'll have your terminal.
With vim 8.1.3741, just type :terminal to start a terminal inside of vim.
Try map :nnoremap ]t :terminal<CR> to do that quicker!
I acknowledge that I am not strictly answering your question, but what has worked better for me when using Vim and Terminals in the same window is Tmux (which is kind of a "run in the background software" like, similar to screen, although this one works better with splits and tabs).
This post will help you to understand how they work together: 'Tmux and Vim — even better together'.
This way we can convert Vim into a powerful IDE
