vi, set user settings - linux

When using vi I almost always need to do
:set hlsearch
:set number
How can I make my system always load these as presets or something when I use vi.
In one machine I am root, in another not. So please include an answer for both. Thank you!

just create a .vimrc file with the following entries:
set hlsearch
set number
Put this file in the $HOME directory of the user you are using on the particular machine:
/root/on the machine where you are root.
/home/USERNAMEon the machine where your user is USERNAME
if .vimrc does not exist, create it.

You can create a file named .exrc in your home directory and write all the commands (without the preceding : ) there.
When you start the vi editor, the editor searches for the environment variable $EXINIT and uses the contents of the file it points to as configuration commands, if it exists. If EXINIT is not defined, vi looks for the .exrc file in your HOME directory, and uses its configuration commands. Finally, vi looks in your current directory for a file named .exrc and executes the commands in that file, if it exists. In this manner, you can have a different vi configuration for each directory or project that you're working on.

The corresponding file for vim is called .vimrc.

How to get to long directory quickly when writting code in VIM

I am writing Bash script using VIM. I need to cd to a directory and run the command tool. The command tool is deep inside the directory. How do I quickly cd to that directory instead of manually typing the directory out in VIM ? In terminal prompt, I can get to the directory quickly using tab. It does not work in VIM.
Thanks

You can change to the currently edited file's directory with :cd %:h; see :help filename-modifiers. Likewise, if you trigger the tool from Vim :! % can do this quickly (and repeat with :!!). Or just :set autochdir, so that the current directory within Vim always follows the currently edited file (and you can then just reference the file via ./).
When typing file paths in vim (as I often do for shell scripts), I find filename-complete invaluable. Simply type <C-X><C-F> in insert mode.
N.B. It does not work in all cases (generally vim prefers the path to be a separate WORD), but a quick edit-complete-fixup isn’t terrible.

gvim: change the default working directory

when I open gvim using Alt+F2 it takes as its default working directory my home folder.
How can I change the working folder after or while running gvim? can i pass that folder as a parameter when open gvim?
You could use a shortcut.
The simplest way, though, would be to
:edit $MYVIMRC
append a line
cd /home/user/my/work/dir
save (optionally execute :w|source % to immediately reload)
Inside vim
use
:pwd
:cd some/other/dir
To view/change current working directory.
Use e.g.
:cd %:h
to change to the directory containing the file loaded in the active window.
If you need/want to do this often, consider just setting 'autochdir'
:se autochdir
From the docs:
When on, Vim will change the current working directory
whenever you open a file, switch buffers, delete a
buffer or open/close a window. It will change to the
directory containing the file which was opened or
selected. This option is provided for backward
compatibility with the Vim released with Sun ONE
Studio 4 Enterprise Edition.
Note: When this option is on some plugins may not work.
You can pass an a folder to gvim (when you have NERDTree then it will be a file tree) You can cd before start to begin in directory you want or use :cd <path> command to change current working directory, which can be passed to -c flag when running Vim:
$ [g]vim -c 'cd <path>'
You can also check current dir using :pwd command.
You can change the working directory with the :cd command. You can also pass this in a command-line option like this:
vim -c "cd wherever"
If you like the working directory to always be the file you're currently editing you can use the set autochdir option. Put that in your ~/.vimrc or see :help autochdir.
I know I'm late, but I started using CDargs which is a bash tool to mark certain directories as bookmarks, then use cdb and press tab to list all the bookmarked directories.
There is a vim plugin that interacts with the settingsfile of this tool: vim-cdargs.
This combo works really nice for me to switch between projects.
Or after opening gvim to go quickly to some bookmarked folder, then use Ctrl-p plugin to quickly find the file I want to edit.
extra hint: I don't even want to type :Cdb so I abbreviated c to expand to :Cdb by adding this to my vimrc:
cnoreabbrev c Cdb
after which typing :c followed by a space, will expand into :Cdb.
EDIT: I now use vim-startify which provides a start page for vim that shows the most recent used files. And with the option let g:startify_change_to_vcs_root = 1 it will change the working directory to the outermost vcs root folder of the file you opened. Which is almost always what I want.
Furthemore, I created my own 'plugin' with some key mappings that will switch to the closest or furthest directory, in the path of the current buffer, containing a .git directory or file. In order to easily switch between searching for files in the current git submodule or in the overal supermodule.
Also I switched to fzf with fzf-vim instead of Ctrl-p, which works significantly faster and is more highly configurable.

Vim record history

Vim stores the list of commands that we applied using : for the current execution.
But when I close vim and start it again, the vim command history is lost.
I tried set history = 1000 in the .vimrc file but that did not help.
Where does Vim maintain the local command history?
What is the command to retain command history?
Just an issue that caught me out the other day, which may or may not be your problem:
On some Linux systems (e.g. Ubuntu), if the very first time you run VIM, you run it as a super-user, then the $HOME/.viminfo file gets created with root owner and your local user does not have permissions to write to it. This explained why my VIM was not storing command history when it was all configured up correctly.
Bottom line: on a *nix system, locate your .viminfo file, and make sure you have read/write permissions on it.
To check whether Vim supports the 'viminfo' file (which stores the history), :echo has('viminfo'). The corresponding setting must not be empty: :set viminfo?, and :set history? should be greater than one.
If there's a problem writing the viminfo file (though Vim should complain in that case), you could try passing a different location via vim -i /tmp/viminfo
You should check the permissions of the .viminfo file. You might need to change owner of the file to your current user using chown or sudo chown.
Mr. Baint has given the answer.
Go to $HOME directory.
give ls -l .viminfo to check permissions.
change permission so that group and owner also can have write
permission. use:
sudo chown yourUserId $HOME/.viminfo
It should fix the issue.
You will have to set the viminfo option. Set it in your $MYVIMRC
Update To find out where the option was last set/changed:
:verbose set viminfo?
See http://vimdoc.sourceforge.net/htmldoc/starting.html#viminfo-file
If you exit Vim and later start it again, you would normally lose a lot of
information. The viminfo file can be used to remember that information, which
enables you to continue where you left off.
This is introduced in section |21.3| of the user manual.
The viminfo file is used to store:
The command line history.
The search string history.
The input-line history.
Contents of non-empty registers.
Marks for several files.
File marks, pointing to locations in files.
Last search/substitute pattern (for 'n' and '&').
The buffer list.
Global variables.
The viminfo file is not supported when the |+viminfo| feature has been
disabled at compile time.
You could also use Session files.
I went round in circles on this one a bit on Ubuntu and set viminfo solutions proposed above resulted in errors.
I eventually did the command "version" in the command mode and it came back with "-" for most stuff including:
-cmdline_hist
-cmdline_info
I ran the following command and it all worked fine again:
sudo apt install vim
I had the same problem. The issue was that I had vim-minimal installed (this is a default with Fedora), which does not support history. I had to uninstall it and install the full vim instead. I now have history... and syntaxic coloration !
If you are using a vimrc file, check your folders and files for existence and correctness
set history=200
set undolevels=128
set undodir=~/.vim/undodir/
set undofile
set undolevels=1000
set undoreload=10000
If the specified folder (undodir in my case) does not exist, the history will not be saved.

Setting up gVim on windows

I am trying to get gVim working on a windows 7 machine and am having the following problems:
Whenever I try to change the _vimrc file, I get a message saying that I don't have permission to save in this location. This is on my home pc btw.
I can't seem to change the directory where the files I edit are being saved. They are all being saved to my desktop at the moment. I tried :set dir=path to where I want to save... with no success.
I wanted to run through vimtutor; however, whenever I type vimtutor into cmd, vim flashes open for a second then closes.
How do I alter the _vimrc file and how do I set the destination for edited files?
I find many people do it differently. Here's how I organize my configurations on windows.
First note that I don't believe in mixing my vim configurations with the stock vim installation. So I don't write or modify files in %PROGRAMFILES% or %PROGRAMFILES(x86)%.
My vim configurations work on different platforms (OS X, linux, windows). And I keep them organized in a .vim folder and a .vimrc file.
Some of my windows machines have cygwin and others do not. On the ones without cygwin, I put my .vim folder and my _vimrc file in %USERPROFILE%. On the ones with cygwin, I put my .vim folder and my _vimrc file in my cygwin user's home directory.
%HOME% is not defined on windows OOTB, so I define it. I find setx.exe is easy...
Example: setx HOME %USERPROFILE% or setx HOME d:\cygwin\home\myname
Alternatively, you can add environment variables via the control panel.
Note, you can copy/store the .vim folder and _vimrc file in %HOME%. But I like to keep them in a git repo elsewhere on my machine and link to them. On windows, I use mlink /d %HOME%\.vim location_of_vim_folder to link the .vim folder. And mlink /h %HOME%\_vimrc location_of_dot_vimrc_file to link the .vimrc to _vimrc file.
Note, you should have write permissions to your %HOME% folder defined above... so this should solve your problem with permissions. (You need to be an administrator to write to %PROGRAMFILES% or %PROGRAMFILES(x86)%
In my vimrc, I have a bit of boiler plate stuff for windows:
"g:my_vim_dir is used elsewhere in my vim configurations
let g:my_vim_dir=expand("$HOME/.vim")
"$HOME/.vim and $HOME/.vim/after are in the &rtp on unix
"But on windows, they need to be added.
if has("win16") || has("win32") || has("win64")
"add g:my_vim_dir to the front of the runtimepath
execute "set rtp^=".g:my_vim_dir
"add g:my_vim_dir\after to the end of the runtimepath
execute "set rtp+=".g:my_vim_dir."\\after"
"Note, pathogen#infect() looks for the 'bundle' folder in each path
"of the &rtp, where the last dir in the '&rtp path' is not 'after'. The
"<path>\bundle\*\after folders will be added if and only if
"the corresponding <path>\after folder is in the &rtp before
"pathogen#infect() is called. So it is very important to add the above
"'after' folder.
"(This applies to vim plugins such as snipmate, tabularize, etc.. that
" are loaded by pathogen (and perhaps vundle too.))
" Not necessary, but I like to cleanup &rtp to use \ instead of /
" when on windows machines
let &rtp=substitute(&rtp,"[/]","\\","g")
"On windows, if called from cygwin or msys, the shell needs to be changed
"to cmd.exe to work with certain plugins that expect cmd.exe on windows versions
"of vim.
if &shell=~#'bash$'
set shell=$COMSPEC " sets shell to correct path for cmd.exe
endif
endif
"Then I load pathogen... (Or if you prefer, you could load vundle bundles here if you wish )
I can't seem to change the directory where the files I edit are being saved. They are all being saved to my desktop at the moment. I tried :set dir=path to where I want to save... with no success.
dir is the location for swap files, which are special backing files used by Vim at runtime.
What you want is cd or lcd which changes the current directory. Type :help cd inside of Vim for more info.
How do I alter the _vimrc file and how do I set the destination for edited files?
I have _vimrc in my Vim folder ($VIM), so when I want to put Vim on a new Windows machine I just copy my entire folder.

Change default location of vimrc

In Vim, is it possible to change the default location of the user vimrc file, i.e., from $HOME/.vimrc to some other location ?
Another solution might be to create a symlink to you preferred location. I have my .vimrc in $HOME/.vim/.vimrc and symlink to it. This way I can have it in a git repo and backup it.
You must start vim with the command vim -u ./path/to/your/vimrcfile
vim -u NONE is a good way to start Vim without any plugin or customisation.
See :help starting.txt for more information.
The VIMINIT variable is my preferred method. The problem with aliasing vim with the -u flag is that if vim is opened in some way other than from the shell command your configuration won't get pulled in. Setting $VIMINIT does not suffer from this drawback. Check this out for more information.
export VIMINIT='source $MYVIMRC'
export MYVIMRC='~/.vim/vimrc' #or any other location you want
Note that Vim normally sets the MYVIMRC variable, though I'm not sure exactly what it's used for. Based on my testing, using VIMINIT in this fashion will result in it not being automatically set on startup as it would normally be. This is why I'm setting it myself.
This works for neovim too!
On Windows, I have the _vimrc that's in my home directory contain one line, source c:\path\to\my.vimrc.
I have not yet worked out a good way to move the entirety of my vimfiles folder, but that's less critical as it's all stuff I've installed from elsewhere. I.e., it'd be easy to restore if I lost it. (I know that I can change runtimepath but my problem is more coming up with a "good" way to do so.)
Update
After six years I extended slightly from what I mention in the comments below; as I put stuff into 'after' and wanted to just keep rtp clean I got something that has been solid for a while now. Today in my %USERPROFILE%\_vimrc I do hardcode the actual paths to things and it changes on every machine I use (and I basically do the same thing on *nix) but this gets copied around mostly-manually when setting up a new PC. I also have a version which I can use to launch Vim on another connected machine on the network, e.g. a co-worker's machine, so I get my config and all that, but the gist is:
set runtimepath^=E:/dotfiles/vim
set runtimepath+=E:/dotfiles/vim/after
set runtimepath-=~/vimfiles
set runtimepath-=~/vimfiles/after
runtime vimrc
and then %USERPROFILE%\_gvimrc just has one line:
runtime gvimrc
(Both vimrc and gvimrc are in the /dotfiles/vim folder and also on Bitbucket.)
I see two options, depending on your needs.
Have ~/.vimrc import the other location
create an alias in your bashrc alias vim="vim -u otherlocation"
I edited
C:\Program Files\Vim\_vimrc
and changed both the runtimepath and sourced my own .vimrc.
I also use these settings in Cygwin (and have them version controlled). So it's this in practice (added at the bottom of the _vimrc file):
let &runtimepath = 'C:\cygwin\home\cygwinaccount\.vim,' . &runtimepath
source C:\cygwin\home\cygwinaccount\.vimrc
Bliss ! :)
In linux:
You can edit .bashrc or .zshrc startup script and add the following lines to change the default location of .vimrc file
export VIMINIT='source $MYVIMRC'
export MYVIMRC='~/.vim/.vimrc' # Note the . (dot) before vimrc. If that is what you have called it.
I feel like the simplest solution is to just have a single line in ~/.vimrc that loads the vimrc from the other location, i.e.:
source PATH/TO/OTHER/LOCATION/.vimrc
