Basic Adjustments

You can override /etc/vim/vimrc with /etc/vim/vimrc.local Create a local copy of /etc/vim/vimrc to let maintainer provide more distribution vimrc, that we don't want to interact during system upgrades. Try to acomplish this in vim itself, because a simple copy will create a ugly source recursion.

   1 % sudo vim /etc/vim/vimrc
   2 ### THEN TYPE:
   3 :% yank
   4 :vsp /etc/vim/vimrc.local
   5 P
   6 /" Source
   7 VGd
   8 :w
   9

or just simply copy it and deal with the error

   1 cp /etc/vim/vimrc{,.local}

Configure vim globally:

skip defaults (mouse mode is irritating)
Enable syntax-highlighting
background=dark
jump to last position
enable indentation plugin
show (partial)cmd in status line
matching brackets
Remove source from the end of file to avoid a sourcing loop

/etc/vim/vimrc.local

   1 " All system-wide defaults are set in $VIMRUNTIME/debian.vim and sourced by
   2 " the call to :runtime you can find below.  If you wish to change any of those
   3 " settings, you should do it in this file (/etc/vim/vimrc), since debian.vim
   4 " will be overwritten everytime an upgrade of the vim packages is performed.
   5 " It is recommended to make changes after sourcing debian.vim since it alters
   6 " the value of the 'compatible' option.

   8 " This line should not be removed as it ensures that various options are
   9 " properly set to work with the Vim-related packages available in Debian.
  10 runtime! debian.vim
  11 
  12 " Vim will load $VIMRUNTIME/defaults.vim if the user does not have a vimrc.
  13 " This happens after /etc/vim/vimrc(.local) are loaded, so it will override
  14 " any settings in these files.
  15 " If you don't want that to happen, uncomment the below line to prevent
  16 " defaults.vim from being loaded.
  17 let g:skip_defaults_vim = 1
  18 
  19 " Uncomment the next line to make Vim more Vi-compatible
  20 " NOTE: debian.vim sets 'nocompatible'.  Setting 'compatible' changes numerous
  21 " options, so any other options should be set AFTER setting 'compatible'.
  22 "set compatible
  23 
  24 " Vim5 and later versions support syntax highlighting. Uncommenting the next
  25 " line enables syntax highlighting by default.
  26 syntax on
  27 
  28 " If using a dark background within the editing area and syntax highlighting
  29 " turn on this option as well
  30 set background=dark
  31 
  32 " Uncomment the following to have Vim jump to the last position when
  33 " reopening a file
  34 au BufReadPost * if line("'\"") > 1 && line("'\"") <= line("$") | exe "normal! g'\"" | endif
  35 
  36 " Uncomment the following to have Vim load indentation rules and plugins
  37 " according to the detected filetype.
  38 filetype plugin indent on
  39 
  40 " The following are commented out as they cause vim to behave a lot
  41 " differently from regular Vi. They are highly recommended though.
  42 set showcmd             " Show (partial) command in status line.
  43 set showmatch           " Show matching brackets.
  44 "set ignorecase         " Do case insensitive matching
  45 "set smartcase          " Do smart case matching
  46 "set incsearch          " Incremental search
  47 "set autowrite          " Automatically save before commands like :next and :make
  48 "set hidden             " Hide buffers when they are abandoned
  49 "set mouse=a            " Enable mouse usage (all modes)

DiffOrig

Copy to registers

Docs

Usage

Need support in vim for +xterm_clipboard Please see #Compiled in features
:registers or short :reg show content of all registers. May be filtered with optional register name like
:reg a b 2 + *
Write and access registers with "
"*yy yank selection into the x11-selection
"+yy yank selection into the x11-clipboard

Vim offers the + and * registers to reference the system clipboard (:help quoteplus and :help quotestar). Note that on some systems, + and * are the same, while on others they are different. Generally on Linux, + and * are different:

+ corresponds to the desktop clipboard (XA_SECONDARY) that is accessed using CTRL-C, CTRL-X, and CTRL-V,
while * corresponds to the X11 primary selection (XA_PRIMARY), which stores the mouse selection and is pasted using the middle mouse button in most applications.

We can use these registers like any other register.

Tabs

Tabs are very useful. You can open many files in tabs using the option vim -p. This can be combined with xargs to find files by a pattern and open them in a vim tab

   1 grep --exclude-dir=.git -Eril "$PATTERN" \
   2         |sort \
   3         |xargs vim -p

This way you can easily hit the default maximum number of tabs (10). But you can easily raise the limit in
~/.vimrc

   1 set tabpagemax=20

Resizing split-screen

   7                 Windows with 'winfixheight' set keep their height and windows

vim-addon-manager

Please see:
- man 5 vim-registry
- man 5 vim-addon-manager

If a debian package provides integration with vim-registry basically a descriptive file in /usr/share/vim/registry it may be managed with the addon manager.

With the following command you can find packages, that register in vim-registry.
apt-file search /usr/share/vim/registry
Notable are especially apparmor, nginx and nftables.

Modelines

https://vim.fandom.com/wiki/Modeline_magic
Has some security implications.

:help auto-setting
:help modeline
:help 'modeline' determines whether to look for modelines
:help 'modelines' number of lines checked to find each modeline

modelines maybe disabled in the system vimrc for security
- enable it with :set modeline in session or .?vimrc
Determine the file format's comment character or sequence
e.g. # ; -- // {* *}  and leave space behind
Place the modeline within 5 lines close to top or bottom
Two syntaxes
1. Without "set", no text can follow the options.
  # vim: syntax=named:sw=4:ts=4:
2. With "set", the modeline ends at the first colon not following a backslash.
  # vim: set syntax=named sw=4 ts=4:
