+
+==============================================================================
+1. Vim arguments *vim-arguments*
+
+Most often, Vim is started to edit a single file with the command
+
+ vim filename *-vim*
+
+More generally, Vim is started with:
+
+ vim [option | filename] ..
+
+Option arguments and file name arguments can be mixed, and any number of them
+can be given. However, watch out for options that take an argument.
+
+For compatibility with various Vi versions, see |cmdline-arguments|.
+
+Exactly one out of the following five items may be used to choose how to
+start editing:
+
+ *-file* *---*
+filename One or more file names. The first one will be the current
+ file and read into the buffer. The cursor will be positioned
+ on the first line of the buffer.
+ To avoid a file name starting with a '-' being interpreted as
+ an option, precede the arglist with "--", e.g.: >
+ vim -- -filename
+< All arguments after the "--" will be interpreted as file names,
+ no other options or "+command" argument can follow.
+
+ *--*
+- This argument can mean two things, depending on whether Ex
+ mode is to be used.
+
+ Starting in Normal mode: >
+ vim -
+ ex -v -
+< Start editing a new buffer, which is filled with text
+ that is read from stdin. The commands that would normally be
+ read from stdin will now be read from stderr. Example: >
+ find . -name "*.c" -print | vim -
+< The buffer will be marked modified, because it contains text
+ that needs to be saved. Except when in readonly mode, then
+ the buffer is not marked modified. Example: >
+ ls | view -
+<
+ Starting in Ex mode: >
+ ex -
+ vim -e -
+ exim -
+ vim -E
+< Start editing in silent mode. See |-s-ex|.
+
+ *-t* *-tag*
+-t {tag} A tag. "tag" is looked up in the tags file, the associated
+ file becomes the current file, and the associated command is
+ executed. Mostly this is used for C programs, in which case
+ "tag" often is a function name. The effect is that the file
+ containing that function becomes the current file and the
+ cursor is positioned on the start of the function (see
+ |tags|).
+
+ *-q* *-qf*
+-q [errorfile] QuickFix mode. The file with the name [errorfile] is read
+ and the first error is displayed. See |quickfix|.
+ If [errorfile] is not given, the 'errorfile' option is used
+ for the file name. See 'errorfile' for the default value.
+ {not in Vi}
+
+(nothing) Without one of the four items above, Vim will start editing a
+ new buffer. It's empty and doesn't have a file name.
+
+
+The startup mode can be changed by using another name instead of "vim", which
+is equal to giving options:
+ex vim -e Start in Ex mode (see |Ex-mode|). *ex*
+exim vim -E Start in improved Ex mode (see |Ex-mode|). *exim*
+ (normally not installed)
+view vim -R Start in read-only mode (see |-R|). *view*
+gvim vim -g Start the GUI (see |gui|). *gvim*
+gex vim -eg Start the GUI in Ex mode. *gex*
+gview vim -Rg Start the GUI in read-only mode. *gview*
+rvim vim -Z Like "vim", but in restricted mode (see |-Z|) *rvim*
+rview vim -RZ Like "view", but in restricted mode. *rview*
+rgvim vim -gZ Like "gvim", but in restricted mode. *rgvim*
+rgview vim -RgZ Like "gview", but in restricted mode. *rgview*
+evim vim -y Easy Vim: set 'insertmode' (see |-y|) *evim*
+eview vim -yR Like "evim" in read-only mode *eview*
+vimdiff vim -d Start in diff mode |diff-mode|
+gvimdiff vim -gd Start in diff mode |diff-mode|
+
+Additional characters may follow, they are ignored. For example, you can have
+"gvim-5" to start the GUI. You must have an executable by that name then, of
+course.
+
+On Unix, you would normally have one executable called Vim, and links from the
+different startup-names to that executable. If your system does not support
+links and you do not want to have several copies of the executable, you could
+use an alias instead. For example: >
+ alias view vim -R
+ alias gvim vim -g
+<
+ *startup-options*
+The option arguments may be given in any order. Single-letter options can be
+combined after one dash. There can be no option arguments after the "--"
+argument.
+
+On VMS all option arguments are assumed to be lowercase, unless preceded with
+a slash. Thus "-R" means recovery and "-/R" readonly.
+
+--help *-h* *--help*
+-h Give usage (help) message and exit. {not in Vi}
+ See |info-message| about capturing the text.
+
+ *--version*
+--version Print version information and exit. Same output as for
+ |:version| command. {not in Vi}
+ See |info-message| about capturing the text.
+
+ *--noplugin*
+--noplugin Skip loading plugins. Resets the 'loadplugins' option.
+ {not in Vi}
+ Note that the |-u| argument may also disable loading plugins:
+ argument load vimrc files load plugins ~
+ (nothing) yes yes
+ -u NONE no no
+ -u NORC no yes
+ --noplugin yes no
+
+ *--literal*
+--literal Take file names literally, don't expand wildcards. Not needed
+ for Unix, because Vim always takes file names literally (the
+ shell expands wildcards).
+ Applies to all the names, also the ones that come before this
+ argument.
+
+ *-+*
++[num] The cursor will be positioned on line "num" for the first
+ file being edited. If "num" is missing, the cursor will be
+ positioned on the last line.
+
+ *-+/*
++/{pat} The cursor will be positioned on the first line containing
+ "pat" in the first file being edited (see |pattern| for the
+ available search patterns).
+
++{command} *-+c* *-c*
+-c {command} {command} will be executed after the first file has been
+ read (and after autocommands and modelines for that file have
+ been processed). "command" is interpreted as an Ex command.
+ If the "command" contains spaces, it must be enclosed in
+ double quotes (this depends on the shell that is used).
+ Example: >
+ vim "+set si" main.c
+ vim "+find stdio.h"
+ vim -c "set ff=dos" -c wq mine.mak
+<
+ Note: You can use up to 10 "+" or "-c" arguments in a Vim
+ command. They are executed in the order given. A "-S"
+ argument counts as a "-c" argument as well.
+ {Vi only allows one command}
+
+--cmd {command} *--cmd*
+ {command} will be executed before processing any vimrc file.
+ Otherwise it acts like -c {command}. You can use up to 10 of
+ these commands, independently from "-c" commands.
+ {not in Vi}
+
+ *-S*
+-S {file} The {file} will be sourced after the first file has been read.
+ This is an easy way to do the equivalent of: >
+ -c "source {file}"
+< It can be mixed with "-c" arguments and repeated like "-c".
+ The limit of 10 "-c" arguments applies here as well.
+ {file} cannot start with a "-".
+ {not in Vi}
+
+-S Works like "-S Session.vim". Only when used as the last
+ argument or when another "-" option follows.
+
+ *-r*
+-r Recovery mode. Without a file name argument, a list of
+ existing swap files is given. With a file name, a swap file
+ is read to recover a crashed editing session. See
+ |crash-recovery|.
+
+ *-L*
+-L Same as -r. {only in some versions of Vi: "List recoverable
+ edit sessions"}
+
+ *-R*
+-R Readonly mode. The 'readonly' option will be set for all the
+ files being edited. You can still edit the buffer, but will
+ be prevented from accidentally overwriting a file. If you
+ forgot that you are in View mode and did make some changes,
+ you can overwrite a file by adding an exclamation mark to
+ the Ex command, as in ":w!". The 'readonly' option can be
+ reset with ":set noro" (see the options chapter, |options|).
+ Subsequent edits will not be done in readonly mode. Calling
+ the executable "view" has the same effect as the -R argument.
+ The 'updatecount' option will be set to 10000, meaning that
+ the swap file will not be updated automatically very often.
+
+ *-m*
+-m Modifications not allowed to be written. The 'write' option
+ will be reset, so that writing files is disabled. However,
+ the 'write' option can be set to enable writing again.
+ {not in Vi}
+
+ *-M*
+-M Modifications not allowed. The 'modifiable' option will be
+ reset, so that changes are not allowed. The 'write' option
+ will be reset, so that writing files is disabled. However,
+ the 'modifiable' and 'write' options can be set to enable
+ changes and writing.
+ {not in Vi}
+
+ *-Z* *restricted-mode* *E145*
+-Z Restricted mode. All commands that make use of an external
+ shell are disabled. This includes suspending with CTRL-Z,
+ ":sh", filtering, the system() function, backtick expansion,
+ etc.
+ {not in Vi}
+
+ *-g*
+-g Start Vim in GUI mode. See |gui|. {not in Vi}
+
+ *-v*
+-v Start Ex in Vi mode. Only makes a difference when the
+ executable is called "ex" or "gvim". For gvim the GUI is not
+ started if possible.
+
+ *-e*
+-e Start Vim in Ex mode |Q|. Only makes a difference when the
+ executable is not called "ex".
+
+ *-E*
+-E Start Vim in improved Ex mode |gQ|. Only makes a difference
+ when the executable is not called "exim".
+ {not in Vi}
+
+ *-s-ex*
+-s Silent or batch mode. Only when Vim was started as "ex" or
+ when preceded with the "-e" argument. Otherwise see |-s|,
+ which does take an argument while this use of "-s" doesn't.
+ To be used when Vim is used to execute Ex commands from a file
+ instead of a terminal. Switches off most prompts and
+ informative messages. Also warnings and error messages.
+ But ":print" output is displayed. And when 'verbose' is
+ non-zero messages are printed (for debugging).
+ If Vim appears to be stuck try typing "qa!<Enter>". You don't
+ get a prompt thus you can't see Vim is waiting for you to type
+ something.
+ Initializations are skipped (except the ones given with the
+ "-u" argument).
+ Example: >
+ vim -e -s < thefilter thefile
+<
+ *-b*
+-b Binary mode. File I/O will only recognize <NL> to separate
+ lines. The 'expandtab' option will be reset. The 'textwidth'
+ option is set to 0. 'modeline' is reset. The 'binary' option
+ is set. This is done after reading the vimrc/exrc files but
+ before reading any file in the arglist. See also
+ |edit-binary|. {not in Vi}
+
+ *-l*
+-l Lisp mode. Sets the 'lisp' and 'showmatch' options on.
+
+ *-A*
+-A Arabic mode. Sets the 'arabic' option on. (Only when
+ compiled with the |+arabic| features (which include
+ |+rightleft|), otherwise Vim gives an error message
+ and exits. {not in Vi}
+
+ *-F*
+-F Farsi mode. Sets the 'fkmap' and 'rightleft' options on.
+ (Only when compiled with |+rightleft| and |+farsi| features,
+ otherwise Vim gives an error message and exits). {not in Vi}
+
+ *-H*
+-H Hebrew mode. Sets the 'hkmap' and 'rightleft' options on.
+ (Only when compiled with the |+rightleft| feature, otherwise
+ Vim gives an error message and exits). {not in Vi}
+
+ *-V* *verbose*
+-V[N] Verbose. Sets the 'verbose' option to [N] (default: 10).
+ Messages will be given for each file that is ":source"d and
+ for reading or writing a viminfo file. Can be used to find
+ out what is happening upon startup and exit. {not in Vi}
+
+ *-D*
+-D Debugging. Go to debugging mode when executing the first
+ command from a script. |debug-mode|
+ {not available when compiled without the |+eval| feature}
+ {not in Vi}
+
+ *-C*
+-C Compatible mode. Sets the 'compatible' option. You can use
+ this to get 'compatible', even though a .vimrc file exists.
+ But the command ":set nocompatible" overrules it anyway.
+ Also see |compatible-default|. {not in Vi}
+
+ *-N*
+-N Not compatible mode. Resets the 'compatible' option. You can
+ use this to get 'nocompatible', when there is no .vimrc file.
+ Also see |compatible-default|. {not in Vi}
+
+ *-y* *easy*
+-y Easy mode. Implied for |evim| and |eview|. Starts with
+ 'insertmode' set and behaves like a click-and-type editor.
+ This sources the script $VIMRUNTIME/evim.vim. Mappings are
+ set up to work like most click-and-type editors, see
+ |evim-keys|. The GUI is started when available.
+ {not in Vi}
+
+ *-n*
+-n No swap file will be used. Recovery after a crash will be
+ impossible. Handy if you want to view or edit a file on a
+ very slow medium (e.g., a floppy).
+ Can also be done with ":set updatecount=0". You can switch it
+ on again by setting the 'updatecount' option to some value,
+ e.g., ":set uc=100".
+ 'updatecount' is set to 0 AFTER executing commands from a
+ vimrc file, but before the GUI initializations. Thus it
+ overrides a setting for 'updatecount' in a vimrc file, but not
+ in a gvimrc file. See |startup|.
+ When you want to reduce accesses to the disk (e.g., for a
+ laptop), don't use "-n", but set 'updatetime' and
+ 'updatecount' to very big numbers, and type ":preserve" when
+ you want to save your work. This way you keep the possibility
+ for crash recovery.
+ {not in Vi}
+
+ *-o*
+-o[N] Open N windows, split horizontally. If [N] is not given,
+ one window is opened for every file given as argument. If
+ there is not enough room, only the first few files get a
+ window. If there are more windows than arguments, the last
+ few windows will be editing an empty file.
+ {not in Vi}
+
+ *-O*
+-O[N] Open N windows, split vertically. Otherwise it's like -o.
+ If both the -o and the -O option are given, the last one on
+ the command line determines how the windows will be split.
+ {not in Vi}
+
+ *-T*
+-T {terminal} Set the terminal type to "terminal". This influences the
+ codes that Vim will send to your terminal. This is normally
+ not needed, because Vim will be able to find out what type
+ of terminal you are using (See |terminal-info|). {not in Vi}
+
+ *-d*
+-d Start in diff mode, like |vimdiff|.
+ {not in Vi} {not available when compiled without the |+diff|
+ feature}
+
+-d {device} Only on the Amiga and when not compiled with the |+diff|
+ feature. Works like "-dev".
+ *-dev*
+-dev {device} Only on the Amiga: The {device} is opened to be used for
+ editing.
+ Normally you would use this to set the window position and
+ size: "-d con:x/y/width/height", e.g.,
+ "-d con:30/10/600/150". But you can also use it to start
+ editing on another device, e.g., AUX:. {not in Vi}
+ *-f*
+-f Amiga: Do not restart Vim to open a new window. This
+ option should be used when Vim is started by a program that
+ will wait for the edit session to finish (e.g., mail or
+ readnews). See |amiga-window|.
+
+ GUI: Do not disconnect from the program that started Vim.
+ 'f' stands for "foreground". If omitted, the GUI forks a new
+ process and exits the current one. "-f" should be used when
+ gvim is started by a program that will wait for the edit
+ session to finish (e.g., mail or readnews). If you want gvim
+ never to fork, include 'f' in 'guioptions' in your .gvimrc.
+ Careful: You can use "-gf" to start the GUI in the foreground,
+ but "-fg" is used to specify the foreground color. |gui-fork|
+ {not in Vi}
+
+ *--nofork*
+--nofork GUI: Do not fork. Same as |-f|.
+ *-u* *E282*
+-u {vimrc} The file {vimrc} is read for initializations. Most other
+ initializations are skipped; see |initialization|. This can
+ be used to start Vim in a special mode, with special
+ mappings and settings. A shell alias can be used to make
+ this easy to use. For example: >
+ alias vimc vim -u ~/.c_vimrc !*
+< Also consider using autocommands; see |autocommand|.
+ When {vimrc} is equal to "NONE" (all uppercase), all
+ initializations from files and environment variables are
+ skipped, including reading the .gvimrc file when the GUI
+ starts. Loading plugins is also skipped.
+ When {vimrc} is equal to "NORC" (all uppercase), this has the
+ same effect as "NONE", but loading plugins is not skipped.
+ Using the "-u" argument has the side effect that the
+ 'compatible' option will be on by default. This can have
+ unexpected effects. See |'compatible'|.
+ {not in Vi}
+
+ *-U* *E230*
+-U {gvimrc} The file "gvimrc" is read for initializations when the GUI
+ starts. Other GUI initializations are skipped. When {gvimrc}
+ is equal to "NONE", no file is read for initializations at
+ all.
+ Exception: Reading the system-wide menu file is always done.
+ {not in Vi}
+
+ *-i*
+-i {viminfo} The file "viminfo" is used instead of the default viminfo
+ file. If the name "NONE" is used (all uppercase), no viminfo
+ file is read or written, even if 'viminfo' is set or when
+ ":rv" or ":wv" are used. See also |viminfo-file|.
+ {not in Vi}
+
+ *-x*
+-x Use encryption to read/write files. Will prompt for a key,
+ which is then stored in the 'key' option. All writes will
+ then use this key to encrypt the text. The '-x' argument is
+ not needed when reading a file, because there is a check if
+ the file that is being read has been encrypted, and Vim asks
+ for a key automatically. |encryption|
+
+ *-X*
+-X Do not try connecting to the X server to get the current
+ window title and copy/paste using the X clipboard. This
+ avoids a long startup time when running Vim in a terminal
+ emulator and the connection to the X server is slow.
+ Only makes a difference on Unix or VMS, when compiled with the
+ |+X11| feature. Otherwise it's ignored.
+ To disable the connection only for specific terminals, see the
+ 'clipboard' option.
+ When the X11 Session Management Protocol (XSMP) handler has
+ been built in, the -X option also disables that connection as
+ it, too, may have undesirable delays.
+ When the connection is desired later anyway (e.g., for
+ client-server messages), call the |serverlist()| function.
+ This does not enable the XSMP handler though.
+ {not in Vi}
+
+ *-s*
+-s {scriptin} The script file "scriptin" is read. The characters in the
+ file are interpreted as if you had typed them. The same can
+ be done with the command ":source! {scriptin}". If the end
+ of the file is reached before the editor exits, further
+ characters are read from the keyboard. Only works when not
+ started in Ex mode, see |-s-ex|. See also |complex-repeat|.
+ {not in Vi}
+
+ *-w*
+-w {scriptout} All the characters that you type are recorded in the file
+ "scriptout", until you exit Vim. This is useful if you want
+ to create a script file to be used with "vim -s" or
+ ":source!". When the "scriptout" file already exists, new
+ characters are appended. See also |complex-repeat|.
+ {not in Vi}
+
+ *-W*
+-W {scriptout} Like -w, but do not append, overwrite an existing file.
+ {not in Vi}
+
+ *-w_nr*
+-w{number} Does nothing. This was included for Vi-compatibility. In Vi
+ it sets the 'window' option, which is not implemented in Vim.
+
+--remote [+{cmd}] {file} ...
+ Open the {file} in another Vim that functions as a server.
+ Any non-file arguments must come before this.
+ See |--remote|. {not in Vi}
+
+--remote-silent [+{cmd}] {file} ...
+ Like --remote, but don't complain if there is no server.
+ See |--remote-silent|. {not in Vi}
+
+--remote-wait [+{cmd}] {file} ...
+ Like --remote, but wait for the server to finish editing the
+ file(s).
+ See |--remote-wait|. {not in Vi}
+
+--remote-wait-silent [+{cmd}] {file} ...
+ Like --remote-wait, but don't complain if there is no server.
+ See |--remote-wait-silent|. {not in Vi}
+
+--servername {name}
+ Specify the name of the Vim server to send to or to become.
+ See |--servername|. {not in Vi}
+
+--remote-send {keys}
+ Send {keys} to a Vim server and exit.
+ See |--remote-send|. {not in Vi}
+
+--remote-expr {expr}
+ Evaluate {expr} in another Vim that functions as a server.
+ The result is printed on stdout.
+ See |--remote-expr|. {not in Vi}
+
+--serverlist Output a list of Vim server names and exit. See
+ See |--serverlist|. {not in Vi}
+
+--socketid {id} *--socketid*
+ GTK+ GUI Vim only. Make gvim try to use GtkPlug mechanism, so
+ that it runs inside another window. See |gui-gtk-socketid|
+ for details. {not in Vi}
+
+--echo-wid *--echo-wid*
+ GTK+ GUI Vim only. Make gvim echo the Window ID on stdout,
+ which can be used to run gvim in a kpart widget. The format
+ of the output is: >
+ WID: 12345\n
+< {not in Vi}
+
+--role {role} *--role*
+ GTK+ 2 GUI only. Set the role of the main window to {role}.
+ The window role can be used by a window manager to uniquely
+ identify a window, in order to restore window placement and
+ such. The --role argument is passed automatically when
+ restoring the session on login. See |gui-gnome-session|
+ {not in Vi}
+
+-P {parent-title} *-P* *MDI* *E671* *E672*
+ Win32 only: Specify the title of the parent application. When
+ possible, Vim will run in an MDI window inside the
+ application.
+ {parent-title} must appear in the window title of the parent
+ application. Make sure that it is specific enough.
+ Note that the implementation is still primitive. It won't
+ work with all applications and the menu doesn't work.
+
+-nb *-nb*
+-nb={fname}
+-nb:{hostname}:{addr}:{password}
+ Attempt connecting to Netbeans and become an editor server for
+ it. The second form specifies a file to read connection info
+ from. The third form specifies the hostname, address and
+ password for connecting to Netbeans. |netbeans-run|
+
+Example for using a script file to change a name in several files:
+ Create a file "subs.vi" containing substitute commands and a :wq
+ command: >
+ :%s/Jones/Smith/g
+ :%s/Allen/Peter/g
+ :wq
+<
+ Execute Vim on all files you want to change: >
+
+ foreach i ( *.let ) vim -s subs.vi $i
+
+If the executable is called "view", Vim will start in Readonly mode. This is
+useful if you can make a hard or symbolic link from "view" to "vim".
+Starting in Readonly mode can also be done with "vim -R".
+
+If the executable is called "ex", Vim will start in "Ex" mode. This means it
+will accept only ":" commands. But when the "-v" argument is given, Vim will
+start in Normal mode anyway.
+
+Additional arguments are available on unix like systems when compiled with
+X11 GUI support. See |gui-resources|.
+
+==============================================================================
+2. Vim on the Amiga *starting-amiga*
+
+Starting Vim from the Workbench *workbench*
+-------------------------------
+
+Vim can be started from the Workbench by clicking on its icon twice. It will
+then start with an empty buffer.
+
+Vim can be started to edit one or more files by using a "Project" icon. The
+"Default Tool" of the icon must be the full pathname of the Vim executable.
+The name of the ".info" file must be the same as the name of the text file.
+By clicking on this icon twice, Vim will be started with the file name as
+current file name, which will be read into the buffer (if it exists). You can
+edit multiple files by pressing the shift key while clicking on icons, and
+clicking twice on the last one. The "Default Tool" for all these icons must
+be the same.
+
+It is not possible to give arguments to Vim, other than file names, from the
+workbench.
+
+Vim window *amiga-window*
+----------
+
+Vim will run in the CLI window where it was started. If Vim was started with
+the "run" or "runback" command, or if Vim was started from the workbench, it
+will open a window of its own.
+
+Technical detail:
+ To open the new window a little trick is used. As soon as Vim
+ recognizes that it does not run in a normal CLI window, it will
+ create a script file in "t:". This script file contains the same
+ command as the one Vim was started with, and an "endcli" command.
+ This script file is then executed with a "newcli" command (the "c:run"
+ and "c:newcli" commands are required for this to work). The script
+ file will hang around until reboot, or until you delete it. This
+ method is required to get the ":sh" and ":!" commands to work
+ correctly. But when Vim was started with the -f option (foreground
+ mode), this method is not used. The reason for this is that
+ when a program starts Vim with the -f option it will wait for Vim to
+ exit. With the script trick, the calling program does not know when
+ Vim exits. The -f option can be used when Vim is started by a mail
+ program which also waits for the edit session to finish. As a
+ consequence, the ":sh" and ":!" commands are not available when the
+ -f option is used.
+
+Vim will automatically recognize the window size and react to window
+resizing. Under Amiga DOS 1.3, it is advised to use the fastfonts program,
+"FF", to speed up display redrawing.
+
+==============================================================================
+3. Running eVim *evim-keys*
+
+EVim runs Vim as click-and-type editor. This is very unlike the original Vi
+idea. But it helps for people that don't use Vim often enough to learn the
+commands. Hopefully they will find out that learning to use Normal mode
+commands will make their editing much more effective.
+
+In Evim these options are changed from their default value:
+
+ :set nocompatible Use Vim improvements
+ :set insertmode Remain in Insert mode most of the time
+ :set hidden Keep invisible buffers loaded
+ :set backup Keep backup files (not for VMS)
+ :set backspace=2 Backspace over everything
+ :set autoindent auto-indent new lines
+ :set history=50 keep 50 lines of Ex commands
+ :set ruler show the cursor position
+ :set incsearch show matches halfway typing a pattern
+ :set mouse=a use the mouse in all modes
+ :set hlsearch highlight all matches for a search pattern
+ :set whichwrap+=<,>,[,] <Left> and <Right> wrap around line breaks
+ :set guioptions-=a non-Unix only: don't do auto-select
+
+Key mappings:
+ <Down> moves by screen lines rather than file lines
+ <Up> idem
+ Q does "gq", formatting, instead of Ex mode
+ <BS> in Visual mode: deletes the selection
+ CTRL-X in Visual mode: Cut to clipboard
+ <S-Del> idem
+ CTRL-C in Visual mode: Copy to clipboard
+ <C-Insert> idem
+ CTRL-V Pastes from the clipboard (in any mode)
+ <S-Insert> idem
+ CTRL-Q do what CTRL-V used to do
+ CTRL-Z undo
+ CTRL-Y redo
+ <M-Space> system menu
+ CTRL-A select all
+ <C-Tab> next window, CTRL-W w
+ <C-F4> close window, CTRL-W c
+
+Additionally:
+- ":behave mswin" is used |:behave|
+- syntax highlighting is enabled
+- filetype detection is enabled, filetype plugins and indenting is enabled
+- in a text file 'textwidth' is set to 78
+
+One hint: If you want to go to Normal mode to be able to type a sequence of
+commands, use CTRL-L. |i_CTRL-L|
+
+==============================================================================
+4. Initialization *initialization* *startup*
+
+This section is about the non-GUI version of Vim. See |gui-fork| for
+additional initialization when starting the GUI.
+
+At startup, Vim checks environment variables and files and sets values
+accordingly. Vim proceeds in this order:
+
+1. Set the 'shell' and 'term' option *SHELL* *COMSPEC* *TERM*
+ The environment variable SHELL, if it exists, is used to set the
+ 'shell' option. On MS-DOS and Win32, the COMSPEC variable is used
+ if SHELL is not set.
+ The environment variable TERM, if it exists, is used to set the 'term'
+ option.
+
+2. Process the arguments
+ The options and file names from the command that start Vim are
+ inspected. Buffers are created for all files (but not loaded yet).
+
+3. Execute Ex commands, from environment variables and/or files
+ An environment variable is read as one Ex command line, where multiple
+ commands must be separated with '|' or "<NL>".
+ *vimrc* *exrc*
+ A file that contains initialization commands is called a "vimrc" file.
+ Each line in a vimrc file is executed as an Ex command line. It is
+ sometimes also referred to as "exrc" file. They are the same type of
+ file, but "exrc" is what Vi always used, "vimrc" is a Vim specific
+ name. Also see |vimrc-intro|.
+
+ Recommended place for your personal initializations:
+ Unix $HOME/.vimrc
+ OS/2 $HOME/.vimrc or $VIM/.vimrc (or _vimrc)
+ MS-DOS and Win32 $HOME/_vimrc or $VIM/_vimrc
+ Amiga s:.vimrc or $VIM/.vimrc
+
+ If Vim was started with "-u filename", the file "filename" is used.
+ All following initializations until 4. are skipped.
+ "vim -u NORC" can be used to skip these initializations without
+ reading a file. "vim -u NONE" also skips loading plugins. |-u|
+
+ If Vim was started in Ex mode with the "-s" argument, all following
+ initializations until 4. are skipped. Only the "-u" option is
+ interpreted.
+ *evim.vim*
+ a. If vim was started as |evim| or |eview| or with the |-y| argument, the
+ script $VIMRUNTIME/evim.vim will be loaded.
+ *system-vimrc*
+ b. For Unix, MS-DOS, MS-Windows, OS/2, VMS, Macintosh, RISC-OS and Amiga
+ the system vimrc file is read for initializations. The path of this
+ file is shown with the ":version" command. Mostly it's "$VIM/vimrc".
+ Note that this file is ALWAYS read in 'compatible' mode, since the
+ automatic resetting of 'compatible' is only done later. Add a ":set
+ nocp" command if you like.
+
+ *VIMINIT* *.vimrc* *_vimrc* *EXINIT* *.exrc* *_exrc*
+ c. Four places are searched for initializations. The first that exists
+ is used, the others are ignored.
+ - The environment variable VIMINIT (see also |compatible-default|) (*)
+ The value of $VIMINIT is used as an Ex command line.
+ - The user vimrc file(s):
+ "$HOME/.vimrc" (for Unix and OS/2) (*)
+ "s:.vimrc" (for Amiga) (*)
+ "home:.vimrc" (for Amiga) (*)
+ "$VIM/.vimrc" (for OS/2 and Amiga) (*)
+ "$HOME/_vimrc" (for MS-DOS and Win32) (*)
+ "$VIM\_vimrc" (for MS-DOS and Win32) (*)
+ Note: For Unix, OS/2 and Amiga, when ".vimrc" does not exist,
+ "_vimrc" is also tried, in case an MS-DOS compatible file
+ system is used. For MS-DOS and Win32 ".vimrc" is checked
+ after "_vimrc", in case long file names are used.
+ Note: For MS-DOS and Win32, "$HOME" is checked first. If no
+ "_vimrc" or ".vimrc" is found there, "$VIM" is tried.
+ See |$VIM| for when $VIM is not set.
+ - The environment variable EXINIT.
+ The value of $EXINIT is used as an Ex command line.
+ - The user exrc file(s). Same as for the user vimrc file, but with
+ "vimrc" replaced by "exrc". But without the (*)!
+
+ d. If the 'exrc' option is on (which is not the default), the current
+ directory is searched for four files. The first that exists is used,
+ the others are ignored.
+ - The file ".vimrc" (for Unix, Amiga and OS/2) (*)
+ "_vimrc" (for MS-DOS and Win32) (*)
+ - The file "_vimrc" (for Unix, Amiga and OS/2) (*)
+ ".vimrc" (for MS-DOS and Win32) (*)
+ - The file ".exrc" (for Unix, Amiga and OS/2)
+ "_exrc" (for MS-DOS and Win32)
+ - The file "_exrc" (for Unix, Amiga and OS/2)
+ ".exrc" (for MS-DOS and Win32)
+
+ (*) Using this file or environment variable will cause 'compatible' to be
+ off by default. See |compatible-default|.
+
+4. Load the plugin scripts. *load-plugins*
+ This does the same as the command: >
+ :runtime! plugin/*.vim
+< The result is that all directories in the 'runtimepath' option will be
+ searched for the "plugin" sub-directory and all files ending in ".vim"
+ will be sourced (in alphabetical order per directory).
+ Loading plugins won't be done when:
+ - The 'loadplugins' option was reset in a vimrc file.
+ - The |--noplugin| command line argument is used.
+ - The "-u NONE" command line argument is used |-u|.
+ - When Vim was compiled without the |+eval| feature.
+ Note that using "-c set noloadplugins" doesn't work, because the
+ commands from the command line have not been executed yet.
+
+5. Set 'shellpipe' and 'shellredir'
+ The 'shellpipe' and 'shellredir' options are set according to the
+ value of the 'shell' option, unless they have been set before.
+ This means that Vim will figure out the values of 'shellpipe' and
+ 'shellredir' for you, unless you have set them yourself.
+
+6. Set 'updatecount' to zero, if "-n" command argument used
+
+7. Set binary options
+ If the "-b" flag was given to Vim, the options for binary editing will
+ be set now. See |-b|.
+
+8. Perform GUI initializations
+ Only when starting "gvim", the GUI initializations will be done. See
+ |gui-init|.
+
+9. Read the viminfo file
+ If the 'viminfo' option is not empty, the viminfo file is read. See
+ |viminfo-file|.
+
+10. Read the quickfix file
+ If the "-q" flag was given to Vim, the quickfix file is read. If this
+ fails, Vim exits.
+
+11. Open all windows
+ When the |-o| flag was given, windows will be opened (but not
+ displayed yet).
+ When switching screens, it happens now. Redrawing starts.
+ If the "-q" flag was given to Vim, the first error is jumped to.
+ Buffers for all windows will be loaded.
+
+12. Execute startup commands
+ If a "-t" flag was given to Vim, the tag is jumped to.
+ The commands given with the |-c| and |+cmd| arguments are executed.
+ If the 'insertmode' option is set, Insert mode is entered.
+ The |VimEnter| autocommands are executed.
+
+Some hints on using initializations:
+
+Standard setup:
+Create a vimrc file to set the default settings and mappings for all your edit
+sessions. Put it in a place so that it will be found by 3b:
+ ~/.vimrc (Unix and OS/2)
+ s:.vimrc (Amiga)
+ $VIM\_vimrc (MS-DOS and Win32)
+Note that creating a vimrc file will cause the 'compatible' option to be off
+by default. See |compatible-default|.
+
+Local setup:
+Put all commands that you need for editing a specific directory only into a
+vimrc file and place it in that directory under the name ".vimrc" ("_vimrc"
+for MS-DOS and Win32). NOTE: To make Vim look for these special files you
+have to turn on the option 'exrc'. See |trojan-horse| too.
+
+System setup:
+This only applies if you are managing a Unix system with several users and
+want to set the defaults for all users. Create a vimrc file with commands
+for default settings and mappings and put it in the place that is given with
+the ":version" command.
+
+Saving the current state of Vim to a file:
+Whenever you have changed values of options or when you have created a
+mapping, then you may want to save them in a vimrc file for later use. See
+|save-settings| about saving the current state of settings to a file.
+
+Avoiding setup problems for Vi users:
+Vi uses the variable EXINIT and the file "~/.exrc". So if you do not want to
+interfere with Vi, then use the variable VIMINIT and the file "vimrc" instead.
+
+Amiga environment variables:
+On the Amiga, two types of environment variables exist. The ones set with the
+DOS 1.3 (or later) setenv command are recognized. See the AmigaDos 1.3
+manual. The environment variables set with the old Manx Set command (before
+version 5.0) are not recognized.
+
+MS-DOS line separators:
+On MS-DOS-like systems (MS-DOS itself, Win32, and OS/2), Vim assumes that all
+the vimrc files have <CR> <NL> pairs as line separators. This will give
+problems if you have a file with only <NL>s and have a line like
+":map xx yy^M". The trailing ^M will be ignored.
+
+ *compatible-default*
+When Vim starts, the 'compatible' option is on. This will be used when Vim
+starts its initializations. But as soon as a user vimrc file is found, or a
+vimrc file in the current directory, or the "VIMINIT" environment variable is
+set, it will be set to 'nocompatible'. This has the side effect of setting or
+resetting other options (see 'compatible'). But only the options that have
+not been set or reset will be changed. This has the same effect like the
+value of 'compatible' had this value when starting Vim. Note that this
+doesn't happen for the system-wide vimrc file.
+
+But there is a side effect of setting or resetting 'compatible' at the moment
+a .vimrc file is found: Mappings are interpreted the moment they are
+encountered. This makes a difference when using things like "<CR>". If the
+mappings depend on a certain value of 'compatible', set or reset it before
+giving the mapping.
+
+The above behavior can be overridden in these ways:
+- If the "-N" command line argument is given, 'nocompatible' will be used,
+ even when no vimrc file exists.
+- If the "-C" command line argument is given, 'compatible' will be used, even
+ when a vimrc file exists.
+- If the "-u {vimrc}" argument is used, 'compatible' will be used.
+- When the name of the executable ends in "ex", then this works like the "-C"
+ argument was given: 'compatible' will be used, even when a vimrc file
+ exists. This has been done to make Vim behave like "ex", when it is started
+ as "ex".
+
+Avoiding trojan horses: *trojan-horse*
+While reading the "vimrc" or the "exrc" file in the current directory, some
+commands can be disabled for security reasons by setting the 'secure' option.
+This is always done when executing the command from a tags file. Otherwise it
+would be possible that you accidentally use a vimrc or tags file that somebody
+else created and contains nasty commands. The disabled commands are the ones
+that start a shell, the ones that write to a file, and ":autocmd". The ":map"
+commands are echoed, so you can see which keys are being mapped.
+ If you want Vim to execute all commands in a local vimrc file, you
+can reset the 'secure' option in the EXINIT or VIMINIT environment variable or
+in the global "exrc" or "vimrc" file. This is not possible in "vimrc" or
+"exrc" in the current directory, for obvious reasons.
+ On Unix systems, this only happens if you are not the owner of the
+vimrc file. Warning: If you unpack an archive that contains a vimrc or exrc
+file, it will be owned by you. You won't have the security protection. Check
+the vimrc file before you start Vim in that directory, or reset the 'exrc'
+option. Some Unix systems allow a user to do "chown" on a file. This makes
+it possible for another user to create a nasty vimrc and make you the owner.
+Be careful!
+ When using tag search commands, executing the search command (the last
+part of the line in the tags file) is always done in secure mode. This works
+just like executing a command from a vimrc/exrc in the current directory.
+
+ *slow-start*
+If Vim takes a long time to start up, there may be a few causes:
+- If the Unix version was compiled with the GUI and/or X11 (check the output
+ of ":version" for "+GUI" and "+X11"), it may need to load shared libraries
+ and connect to the X11 server. Try compiling a version with GUI and X11
+ disabled. This also should make the executable smaller.
+ Use the |-X| command line argument to avoid connecting to the X server when
+ running in a terminal.
+- If you have "viminfo" enabled, the loading of the viminfo file may take a
+ while. You can find out if this is the problem by disabling viminfo for a
+ moment (use the Vim argument "-i NONE", |-i|). Try reducing the number of
+ lines stored in a register with ":set viminfo='20,<50,s10". |viminfo-file|.
+
+ *:intro*
+When Vim starts without a file name, an introductory message is displayed (for
+those who don't know what Vim is). It is removed as soon as the display is
+redrawn in any way. To see the message again, use the ":intro" command (if
+there is not enough room, you will see only part of it).
+ To avoid the intro message on startup, add the 'I' flag to 'shortmess'.
+
+ *info-message*
+The |--help| and |--version| arguments cause Vim to print a message and then
+exit. Normally the message is send to stdout, thus can be redirected to a
+file with: >
+
+ vim --help >file
+
+From inside Vim: >
+
+ :read !vim --help
+
+When using gvim, it detects that it might have been started from the desktop,
+without a terminal to show messages on. This is detected when both stdout and
+stderr are not a tty. This breaks the ":read" command, as used in the example
+above. To make it work again, set 'shellredir' to ">" instead of the default
+">&": >
+
+ :set shellredir=>
+ :read !gvim --help
+
+This still won't work for systems where gvim does not use stdout at all
+though.
+
+==============================================================================
+5. $VIM and $VIMRUNTIME
+ *$VIM*
+The environment variable "$VIM" is used to locate various user files for Vim,
+such as the user startup script ".vimrc". This depends on the system, see
+|startup|.
+
+To avoid the need for every user to set the $VIM environment variable, Vim
+will try to get the value for $VIM in this order:
+1. The value defined by the $VIM environment variable. You can use this to
+ make Vim look in a specific directory for its support files. Example: >
+ setenv VIM /home/paul/vim
+2. The path from 'helpfile' is used, unless it contains some environment
+ variable too (the default is "$VIMRUNTIME/doc/help.txt": chicken-egg
+ problem). The file name ("help.txt" or any other) is removed. Then
+ trailing directory names are removed, in this order: "doc", "runtime" and
+ "vim{version}" (e.g., "vim54").
+3. For MSDOS, Win32 and OS/2 Vim tries to use the directory name of the
+ executable. If it ends in "/src", this is removed. This is useful if you
+ unpacked the .zip file in some directory, and adjusted the search path to
+ find the vim executable. Trailing directory names are removed, in this
+ order: "runtime" and "vim{version}" (e.g., "vim54").
+4. For Unix the compile-time defined installation directory is used (see the
+ output of ":version").
+
+Once Vim has done this once, it will set the $VIM environment variable. To
+change it later, use a ":let" command like this: >
+ :let $VIM = "/home/paul/vim/"
+<
+ *$VIMRUNTIME*
+The environment variable "$VIMRUNTIME" is used to locate various support
+files, such as the on-line documentation and files used for syntax
+highlighting. For example, the main help file is normally
+"$VIMRUNTIME/doc/help.txt".
+You don't normally set $VIMRUNTIME yourself, but let Vim figure it out. This
+is the order used to find the value of $VIMRUNTIME:
+1. If the environment variable $VIMRUNTIME is set, it is used. You can use
+ this when the runtime files are in an unusual location.
+2. If "$VIM/vim{version}" exists, it is used. {version} is the version
+ number of Vim, without any '-' or '.'. For example: "$VIM/vim54". This is
+ the normal value for $VIMRUNTIME.
+3. If "$VIM/runtime" exists, it is used.
+4. The value of $VIM is used. This is for backwards compatibility with older
+ versions.
+5. When the 'helpfile' option is set and doesn't contain a '$', its value is
+ used, with "doc/help.txt" removed from the end.
+
+For Unix, when there is a compiled-in default for $VIMRUNTIME (check the
+output of ":version"), steps 2, 3 and 4 are skipped, and the compiled-in
+default is used after step 5. This means that the compiled-in default
+overrules the value of $VIM. This is useful if $VIM is "/etc" and the runtime
+files are in "/usr/share/vim/vim54".
+
+Once Vim has done this once, it will set the $VIMRUNTIME environment variable.
+To change it later, use a ":let" command like this: >
+ :let $VIMRUNTIME = "/home/piet/vim/vim54"
+
+==============================================================================
+6. Suspending *suspend*
+
+ *iconize* *iconise* *CTRL-Z* *v_CTRL-Z*
+CTRL-Z Suspend Vim, like ":stop".
+ Works in Normal and in Visual mode. In Insert and
+ Command-line mode, the CTRL-Z is inserted as a normal
+ character. In Visual mode Vim goes back to Normal
+ mode.
+
+
+:sus[pend][!] or *:sus* *:suspend* *:st* *:stop*
+:st[op][!] Suspend Vim.
+ If the '!' is not given and 'autowrite' is set, every
+ buffer with changes and a file name is written out.
+ If the '!' is given or 'autowrite' is not set, changed
+ buffers are not written, don't forget to bring Vim
+ back to the foreground later!
+
+In the GUI, suspending is implemented as iconising gvim. In Windows 95/NT,
+gvim is minimized.
+
+On many Unix systems, it is possible to suspend Vim with CTRL-Z. This is only
+possible in Normal and Visual mode (see next chapter, |vim-modes|). Vim will
+continue if you make it the foreground job again. On other systems, CTRL-Z
+will start a new shell. This is the same as the ":sh" command. Vim will
+continue if you exit from the shell.
+
+In X-windows the selection is disowned when Vim suspends. this means you
+can't paste it in another application (since Vim is going to sleep an attempt
+to get the selection would make the program hang).
+
+==============================================================================
+7. Saving settings *save-settings*
+
+Mostly you will edit your vimrc files manually. This gives you the greatest
+flexibility. There are a few commands to generate a vimrc file automatically.
+You can use these files as they are, or copy/paste lines to include in another
+vimrc file.
+
+ *:mk* *:mkexrc*
+:mk[exrc] [file] Write current key mappings and changed options to
+ [file] (default ".exrc" in the current directory),
+ unless it already exists. {not in Vi}
+
+:mk[exrc]! [file] Always write current key mappings and changed
+ options to [file] (default ".exrc" in the current
+ directory). {not in Vi}
+
+ *:mkv* *:mkvimrc*
+:mkv[imrc][!] [file] Like ":mkexrc", but the default is ".vimrc" in the
+ current directory. The ":version" command is also
+ written to the file. {not in Vi}
+
+These commands will write ":map" and ":set" commands to a file, in such a way
+that when these commands are executed, the current key mappings and options
+will be set to the same values. The options 'columns', 'endofline',
+'fileformat', 'key', 'lines', 'modified', 'scroll', 'term', 'textmode',
+'ttyfast' and 'ttymouse' are not included, because these are terminal or file
+dependent. Note that the options 'binary', 'paste' and 'readonly' are
+included, this might not always be what you want.
+
+When special keys are used in mappings, The 'cpoptions' option will be
+temporarily set to its Vim default, to avoid the mappings to be
+misinterpreted. This makes the file incompatible with Vi, but makes sure it
+can be used with different terminals.
+
+Only global mappings are stored, not mappings local to a buffer.
+
+A common method is to use a default ".vimrc" file, make some modifications
+with ":map" and ":set" commands and write the modified file. First read the
+default ".vimrc" in with a command like ":source ~piet/.vimrc.Cprogs", change
+the settings and then save them in the current directory with ":mkvimrc!". If
+you want to make this file your default .vimrc, move it to your home directory
+(on Unix), s: (Amiga) or $VIM directory (MS-DOS). You could also use
+autocommands |autocommand| and/or modelines |modeline|.
+
+If you only want to add a single option setting to your vimrc, you can use
+these steps:
+1. Edit your vimrc file with Vim.
+2. Play with the option until it's right. E.g., try out different values for
+ 'guifont'.
+3. Append a line to set the value of the option, using the expression register
+ '=' to enter the value. E.g., for the 'guifont' option: >
+ o:set guifont=<C-R>=&guifont<CR><Esc>
+< [<C-R> is a CTRL-R, <CR> is a return, <Esc> is the escape key]
+
+Note that when you create a .vimrc file, this can influence the 'compatible'
+option, which has several side effects. See |'compatible'|.
+":mkvimrc", ":mkexrc" and ":mksession" write the command to set or reset the
+'compatible' option to the output file first, because of these side effects.
+
+==============================================================================
+8. Views and Sessions *views-sessions*
+
+This is introduced in sections |21.4| and |21.5| of the user manual.
+
+ *View* *view-file*
+A View is a collection of settings that apply to one window. You can save a
+View and when you restore it later, the text is displayed in the same way.
+The options and mappings in this window will also be restored, so that you can
+continue editing like when the View was saved.
+
+ *Session* *session-file*
+A Session keeps the Views for all windows, plus the global settings. You can
+save a Session and when you restore it later the window layout looks the same.
+You can use a Session to quickly switch between different projects,
+automatically loading the files you were last working on in that project.
+
+Views and Sessions are a nice addition to viminfo-files, which are used to
+remember information for all Views and Sessions together |viminfo-file|.
+
+You can quickly start editing with a previously saved View or Session with the
+|-S| argument: >
+ vim -S Session.vim
+<
+All this is {not in Vi} and {not available when compiled without the
+|+mksession| feature}.
+
+ *:mks* *:mksession*
+:mks[ession][!] [file] Write a Vim script that restores the current editing
+ session.
+ When [!] is included an existing file is overwritten.
+ When [file] is omitted "Session.vim" is used.
+
+The output of ":mksession" is like ":mkvimrc", but additional commands are
+added to the file. Which ones depends on the 'sessionoptions' option. The
+resulting file, when executed with a ":source" command:
+1. Restores global mappings and options, if 'sessionoptions' contains
+ "options". Script-local mappings will not be written.
+2. Restores global variables that start with an uppercase letter and contain
+ at least one lowercase letter, if 'sessionoptions' contains "globals".
+3. Unloads all currently loaded buffers.
+4. Restores the current directory if 'sessionoptions' contains "curdir", or
+ sets the current directory to where the Session file is if 'sessionoptions'
+ contains "sesdir".
+5. Restores GUI Vim window position, if 'sessionoptions' contains "winpos".
+6. Restores screen size, if 'sessionoptions' contains "resize".
+7. Reloads the buffer list, with the last cursor positions. If
+ 'sessionoptions' contains "buffers" then all buffers are restored,
+ including hidden and unloaded buffers. Otherwise only buffers in windows
+ are restored.
+8. Restores all windows with the same layout. If 'sessionoptions' contains
+ contains "help", help windows are restored. If 'sessionoptions' contains
+ "blank", windows editing a buffer without a name will be restored.
+ If 'sessionoptions' contains "winsize" and no (help/blank) windows were
+ left out, the window sizes are restored (relative to the screen size).
+ Otherwise, the windows are just given sensible sizes.
+9. Restores the Views for all the windows, as with |:mkview|. But
+ 'sessionoptions' is used instead of 'viewoptions'.
+10. If a file exists with the same name as the Session file, but ending in
+ "x.vim" (for eXtra), executes that as well. You can use *x.vim files to
+ specify additional settings and actions associated with a given Session,
+ such as creating menu items in the GUI version.
+
+After restoring the Session, the full filename of your current Session is
+available in the internal variable "v:this_session" |this_session-variable|.
+An example mapping: >
+ :nmap <F2> :wa<Bar>exe "mksession! " . v:this_session<CR>:so ~/sessions/
+This saves the current Session, and starts off the command to load another.
+
+ *:mkvie* *:mkview*
+:mkvie[w][!] [file] Write a Vim script that restores the contents of the
+ current window.
+ When [!] is included an existing file is overwritten.
+ When [file] is omitted or is a number from 1 to 9, a
+ name is generated and 'viewdir' prepended. When last
+ directory name in 'viewdir' does not exist, this
+ directory is created.
+ An existing file is always overwritten then. Use
+ |:loadview| to load this view again.
+ When [file] is the name of a file ('viewdir' is not
+ used), a command to edit the file is added to the
+ generated file.
+
+The output of ":mkview" contains these items:
+1. The argument list used in the window. When the global argument list is
+ used it is reset to the global list.
+ The index in the argument list is also restored.
+2. The file being edited in the window. If there is no file, the window is
+ made empty.
+3. Restore mappings, abbreviations and options local to the window if
+ 'viewoptions' contains "options" or "localoptions". For the options it
+ restores only values that are local to the current buffer and values local
+ to the window.
+ When storing the view as part of a session and "options" is in
+ 'sessionoptions', global values for local options will be stored too.
+4. Restore folds when using manual folding and 'viewoptions' contains
+ "folds". Restore manually opened and closed folds.
+5. The scroll position and the cursor position in the file. Doesn't work very
+ well when there are closed folds.
+6. The local current directory, if it is different from the global current
+ directory.
+
+Note that Views and Sessions are not perfect:
+- They don't restore everything. For example, defined functions, autocommands
+ and ":syntax on" are not included. Things like register contents and
+ command line history are in viminfo, not in Sessions or Views.
+- Global option values are only set when the differ from the default value.
+ When the current value is not the default value, loading a Session will not
+ set it back to the default value. Local options will be set back to the
+ default value though.
+- Existing mappings will be overwritten without warning. An existing mapping
+ may cause an error for ambiguity.
+- When storing manual folds and when storing manually opened/closed folds,
+ changes in the file between saving and loading the view will mess it up.
+- The Vim script is not very efficient. But still faster than typing the
+ commands yourself!
+
+ *:lo* *:loadview*
+:lo[adview] [nr] Load the view for the current file. When [nr] is
+ omitted, the view stored with ":mkview" is loaded.
+ When [nr] is specified, the view stored with ":mkview
+ [nr]" is loaded.
+
+The combination of ":mkview" and ":loadview" can be used to store up to ten
+different views of a file. These are remembered in the directory specified
+with the 'viewdir' option. The views are stored using the file name. If a
+file is renamed or accessed through a (symbolic) link the view will not be
+found.
+
+You might want to clean up your 'viewdir' directory now and then.
+
+To automatically save and restore views for *.c files: >
+ au BufWinLeave *.c mkview
+ au BufWinEnter *.c silent loadview

+==============================================================================
+9. The viminfo file *viminfo* *viminfo-file* *E136*
+ *E575* *E576* *E577*
+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 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 a Session file. The difference is that the viminfo file
+does not depend on what you are working on. There normally is only one
+viminfo file. Session files are used to save the state of a specific editing
+Session. You could have several Session files, one for each project you are
+working on. Viminfo and Session files together can be used to effectively
+enter Vim and directly start working in your desired setup. |session-file|
+
+ *viminfo-read*
+When Vim is started and the 'viminfo' option is non-empty, the contents of
+the viminfo file are read and the info can be used in the appropriate places.
+The marks are not read in at startup (but file marks are). See
+|initialization| for how to set the 'viminfo' option upon startup.
+
+ *viminfo-write*
+When Vim exits and 'viminfo' is non-empty, the info is stored in the viminfo
+file (it's actually merged with the existing one, if one exists). The
+'viminfo' option is a string containing information about what info should be
+stored, and contains limits on how much should be stored (see 'viminfo').
+
+Notes for Unix:
+- The file protection for the viminfo file will be set to prevent other users
+ from being able to read it, because it may contain any text or commands that
+ you have worked with.
+- If you want to share the viminfo file with other users (e.g. when you "su"
+ to another user), you can make the file writable for the group or everybody.
+ Vim will preserve this when writing new viminfo files. Be careful, don't
+ allow just anybody to read and write your viminfo file!
+- Vim will not overwrite a viminfo file that is not writable by the current
+ "real" user. This helps for when you did "su" to become root, but your
+ $HOME is still set to a normal user's home directory. Otherwise Vim would
+ create a viminfo file owned by root that nobody else can read.
+
+Marks are stored for each file separately. When a file is read and 'viminfo'
+is non-empty, the marks for that file are read from the viminfo file. NOTE:
+The marks are only written when exiting Vim, which is fine because marks are
+remembered for all the files you have opened in the current editing session,
+unless ":bdel" is used. If you want to save the marks for a file that you are
+about to abandon with ":bdel", use ":wv". The '[' and ']' marks are not
+stored, but the '"' mark is. The '"' mark is very useful for jumping to the
+cursor position when the file was last exited. No marks are saved for files
+that start with any string given with the "r" flag in 'viminfo'. This can be
+used to avoid saving marks for files on removable media (for MS-DOS you would
+use "ra:,rb:", for Amiga "rdf0:,rdf1:,rdf2:").
+
+ *viminfo-file-marks*
+Uppercase marks ('A to 'Z) are stored when writing the viminfo file. The
+numbered marks ('0 to '9) are a bit special. When the viminfo file is written
+(when exiting or with the ":wviminfo" command), '0 is set to the current cursor
+position and file. The old '0 is moved to '1, '1 to '2, etc. This
+resembles what happens with the "1 to "9 delete registers. If the current
+cursor position is already present in '0 to '9, it is moved to '0, to avoid
+having the same position twice. The result is that with "'0", you can jump
+back to the file and line where you exited Vim. To do that right away, try
+using this command: >
+
+ vim -c "normal '0"
+
+In a shell you could make an alias for it: >
+
+ alias lvim vim -c '"'normal "'"0'"'
+
+Use the "r" flag in 'viminfo' to specify for which files no marks should be
+remembered.
+
+
+VIMINFO FILE NAME *viminfo-file-name*
+
+- The default name of the viminfo file is "$HOME/.viminfo" for Unix and OS/2,
+ "s:.viminfo" for Amiga, "$HOME\_viminfo" for MS-DOS and Win32. For the last
+ two, when $HOME is not set, "$VIM\_viminfo" is used. When $VIM is also not
+ set, "c:\_viminfo" is used. For OS/2 "$VIM/.viminfo" is used when $HOME is
+ not set and $VIM is set.
+- The 'n' flag in the 'viminfo' option can be used to specify another viminfo
+ file name |'viminfo'|.
+- The "-i" Vim argument can be used to set another file name, |-i|. When the
+ file name given is "NONE" (all uppercase), no viminfo file is ever read or
+ written. Also not for the commands below!
+- For the commands below, another file name can be given, overriding the
+ default and the name given with 'viminfo' or "-i" (unless it's NONE).
+
+
+CHARACTER ENCODING *viminfo-encoding*
+
+The text in the viminfo file is encoded as specified with the 'encoding'
+option. Normally you will always work with the same 'encoding' value, and
+this works just fine. However, if you read the viminfo file with another
+value for 'encoding' than what it was written with, some of the text
+(non-ASCII characters) may be invalid. If this is unacceptable, add the 'c'
+flag to the 'viminfo' option: >
+ :set viminfo+=c
+Vim will then attempt to convert the text in the viminfo file from the
+'encoding' value it was written with to the current 'encoding' value. This
+requires Vim to be compiled with the |+iconv| feature. Filenames are not
+converted.
+
+
+MANUALLY READING AND WRITING
+
+Two commands can be used to read and write the viminfo file manually. This
+can be used to exchange registers between two running Vim programs: First
+type ":wv" in one and then ":rv" in the other. Note that if the register
+already contained something, then ":rv!" would be required. Also note
+however that this means everything will be overwritten with information from
+the first Vim, including the command line history, etc.
+
+The viminfo file itself can be edited by hand too, although we suggest you
+start with an existing one to get the format right. It is reasonably
+self-explanatory once you're in there. This can be useful in order to
+create a second file, say "~/.my_viminfo" which could contain certain
+settings that you always want when you first start Vim. For example, you
+can preload registers with particular data, or put certain commands in the
+command line history. A line in your .vimrc file like >
+ :rviminfo! ~/.my_viminfo
+can be used to load this information. You could even have different viminfos
+for different types of files (e.g., C code) and load them based on the file
+name, using the ":autocmd" command (see |:autocmd|).
+
+ *viminfo-errors*
+When Vim detects an error while reading a viminfo file, it will not overwrite
+that file. If there are more than 10 errors, Vim stops reading the viminfo
+file. This was done to avoid accidentally destroying a file when the file
+name of the viminfo file is wrong. This could happen when accidentally typing
+"vim -i file" when you wanted "vim -R file" (yes, somebody accidentally did
+that!). If you want to overwrite a viminfo file with an error in it, you will
+either have to fix the error, or delete the file (while Vim is running, so
+most of the information will be restored).
+
+ *:rv* *:rviminfo* *E195*
+:rv[iminfo][!] [file] Read from viminfo file [file] (default: see above).
+ If [!] is given, then any information that is
+ already set (registers, marks, etc.) will be
+ overwritten. {not in Vi}
+
+ *:wv* *:wviminfo* *E137* *E138* *E574*
+:wv[iminfo][!] [file] Write to viminfo file [file] (default: see above).
+ The information in the file is first read in to make
+ a merge between old and new info. When [!] is used,
+ the old information is not read first, only the
+ internal info is written. If 'viminfo' is empty, marks
+ for up to 100 files will be written.
+ When you get error "E138: Can't write viminfo file"
+ check that no old temp files were left behind (e.g.
+ ~/.viminf*) and that you can write in the directory of
+ the .viminfo file.
+ {not in Vi}
