15 ==============================================================================
16 1. Common functionality *clientserver*
18 When compiled with the |+clientserver| option, Vim can act as a command
19 server. It accepts messages from a client and executes them. At the same
20 time, Vim can function as a client and send commands to a Vim server.
22 The following command line arguments are available:
26 --remote [+{cmd}] {file} ... *--remote*
27 Open the file list in a remote Vim. When
28 there is no Vim server, execute locally.
29 There is one optional init command: +{cmd}.
30 This must be an Ex command that can be
32 The rest of the command line is taken as the
33 file list. Thus any non-file arguments must
35 You cannot edit stdin this way |--|.
36 The remote Vim is raised. If you don't want
38 vim --remote-send "<C-\><C-N>:n filename<CR>"
39 < --remote-silent [+{cmd}] {file} ... *--remote-silent*
40 As above, but don't complain if there is no
41 server and the file is edited locally.
42 --remote-wait [+{cmd}] {file} ... *--remote-wait*
43 As --remote, but wait for files to complete
44 (unload) in remote Vim.
45 --remote-wait-silent [+{cmd}] {file} ... *--remote-wait-silent*
46 As --remote-wait, but don't complain if there
49 --remote-tab Like --remote but open each file in a new
52 --remote-tab-silent Like --remote-silent but open each file in a
55 --remote-tab-wait Like --remote-wait but open each file in a new
58 *--remote-tab-wait-silent*
59 --remote-tab-wait-silent Like --remote-wait-silent but open each file
62 --servername {name} Become the server {name}. When used together
63 with one of the --remote commands: connect to
64 server {name} instead of the default (see
67 --remote-send {keys} Send {keys} to server and exit. The {keys}
68 are not mapped. Special key names are
69 recognized, e.g., "<CR>" results in a CR
72 --remote-expr {expr} Evaluate {expr} in server and print the result
75 --serverlist Output a list of server names.
80 Edit "file.txt" in an already running GVIM server: >
81 gvim --remote file.txt
83 Edit "file.txt" in an already running server called FOOBAR: >
84 gvim --servername FOOBAR --remote file.txt
86 Edit "file.txt" in server "FILES" if it exists, become server "FILES"
88 gvim --servername FILES --remote-silent file.txt
90 This doesn't work, all arguments after --remote will be used as file names: >
91 gvim --remote --servername FOOBAR file.txt
93 Edit file "+foo" in a remote server (note the use of "./" to avoid the special
94 meaning of the leading plus): >
97 Tell the remote server "BLA" to write all files and exit: >
98 vim --servername BLA --remote-send '<C-\><C-N>:wqa<CR>'
103 By default Vim will try to register the name under which it was invoked (gvim,
104 egvim ...). This can be overridden with the --servername argument. If the
105 specified name is not available, a postfix is applied until a free name is
106 encountered, i.e. "gvim1" for the second invocation of gvim on a particular
107 X-server. The resulting name is available in the servername builtin variable
108 |v:servername|. The case of the server name is ignored, thus "gvim" and
109 "GVIM" are considered equal.
111 When Vim is invoked with --remote, --remote-wait or --remote-send it will try
112 to locate the server name determined by the invocation name and --servername
113 argument as described above. If an exact match is not available, the first
114 server with the number postfix will be used. If a name with the number
115 postfix is specified with the --servername argument, it must match exactly.
117 If no server can be located and --remote or --remote-wait was used, Vim will
118 start up according to the rest of the command line and do the editing by
119 itself. This way it is not necessary to know whether gvim is already started
120 when sending command to it.
122 The --serverlist argument will cause Vim to print a list of registered command
123 servers on the standard output (stdout) and exit.
125 Win32 Note: Making the Vim server go to the foreground doesn't always work,
126 because MS-Windows doesn't allow it. The client will move the server to the
127 foreground when using the --remote or --remote-wait argument and the server
128 name starts with "g".
133 The --remote argument will cause a |:drop| command to be constructed from the
134 rest of the command line and sent as described above.
135 The --remote-wait argument does the same thing and additionally sets up to
136 wait for each of the files to have been edited. This uses the BufUnload
137 event, thus as soon as a file has been unloaded, Vim assumes you are done
139 Note that the --remote and --remote-wait arguments will consume the rest of
140 the command line. I.e. all remaining arguments will be regarded as filenames.
141 You can not put options there!
146 There are a number of Vim functions for scripting the command server. See
147 the description in |eval.txt| or use CTRL-] on the function name to jump to
148 the full explanation.
150 synopsis explanation ~
151 remote_expr( server, string, idvar) send expression
152 remote_send( server, string, idvar) send key sequence
153 serverlist() get a list of available servers
154 remote_peek( serverid, retvar) check for reply string
155 remote_read( serverid) read reply string
156 server2client( serverid, string) send reply string
157 remote_foreground( server) bring server to the front
159 See also the explanation of |CTRL-\_CTRL-N|. Very useful as a leading key
161 The {serverid} for server2client() can be obtained with expand("<client>")

164 2. X11 specific items *x11-clientserver*
165 *E247* *E248* *E251* *E258* *E277*
167 The communication between client and server goes through the X server. The
168 display of the Vim server must be specified. The usual protection of the X
169 server is used, you must be able to open a window on the X server for the
170 communication to work. It is possible to communicate between different
173 By default, a GUI Vim will register a name on the X-server by which it can be
174 addressed for subsequent execution of injected strings. Vim can also act as
175 a client and send strings to other instances of Vim on the same X11 display.
177 When an X11 GUI Vim (gvim) is started, it will try to register a send-server
178 name on the 'VimRegistry' property on the root window.
180 A non GUI Vim with access to the X11 display (|xterm-clipboard| enabled), can
181 also act as a command server if a server name is explicitly given with the
182 --servername argument.
184 An empty --servername argument will cause the command server to be disabled.
186 To send commands to a Vim server from another application, read the source
187 file src/if_xcmdsrv.c, it contains some hints about the protocol used.
189 ==============================================================================
190 3. Win32 specific items *w32-clientserver*
192 Every Win32 Vim can work as a server, also in the console. You do not need a
193 version compiled with OLE. Windows messages are used, this works on any
194 version of MS-Windows. But only communication within one system is possible.
196 Since MS-Windows messages are used, any other application should be able to
197 communicate with a Vim server. An alternative is using the OLE functionality
200 When using gvim, the --remote-wait only works properly this way: >
202 start /w gvim --remote-wait file.txt
