| 15 ============================================================================== | |
| 16 1. Common functionality *clientserver* | |
| 17 | |
| 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. | |
| 21 | |
| 22 The following command line arguments are available: | |
| 23 | |
| 24 argument meaning ~ | |
| 25 | |
| 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 | |
| 31 followed by "|". | |
| 32 The rest of the command line is taken as the | |
| 33 file list. Thus any non-file arguments must | |
| 34 come before this. | |
| 35 You cannot edit stdin this way |--|. | |
| 36 The remote Vim is raised. If you don't want | |
| 37 this use > | |
| 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 | |
| 47 is no server. | |
| 856 | 48 *--remote-tab* |
| 733 | 49 --remote-tab Like --remote but open each file in a new |
| 856 | 50 tabpage. |
| 51 *--remote-tab-silent* | |
| 733 | 52 --remote-tab-silent Like --remote-silent but open each file in a |
| 856 | 53 new tabpage. |
| 733 | 54 *--remote-tab-wait* |
| 55 --remote-tab-wait Like --remote-wait but open each file in a new | |
| 856 | 56 tabpage. |
| 733 | 57 |
| 856 | 58 *--remote-tab-wait-silent* |
| 733 | 59 --remote-tab-wait-silent Like --remote-wait-silent but open each file |
| 856 | 60 in a new tabpage. |
| 7 | 61 *--servername* |
| 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 | |
| 65 below). | |
| 66 *--remote-send* | |
| 1624 | 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 | |
| 70 character. | |
| 7 | 71 *--remote-expr* |
| 714 | 72 --remote-expr {expr} Evaluate {expr} in server and print the result |
| 856 | 73 on stdout. |
| 7 | 74 *--serverlist* |
| 75 --serverlist Output a list of server names. | |
| 76 | |
| 77 | |
| 78 Examples ~ | |
| 79 | |
| 80 Edit "file.txt" in an already running GVIM server: > | |
| 81 gvim --remote file.txt | |
| 82 | |
| 83 Edit "file.txt" in an already running server called FOOBAR: > | |
| 84 gvim --servername FOOBAR --remote file.txt | |
| 85 | |
| 86 Edit "file.txt" in server "FILES" if it exists, become server "FILES" | |
| 87 otherwise: > | |
| 88 gvim --servername FILES --remote-silent file.txt | |
| 89 | |
| 90 This doesn't work, all arguments after --remote will be used as file names: > | |
| 91 gvim --remote --servername FOOBAR file.txt | |
| 92 | |
| 93 Edit file "+foo" in a remote server (note the use of "./" to avoid the special | |
| 94 meaning of the leading plus): > | |
| 95 vim --remote ./+foo | |
| 96 | |
| 97 Tell the remote server "BLA" to write all files and exit: > | |
| 98 vim --servername BLA --remote-send '<C-\><C-N>:wqa<CR>' | |
| 99 | |
| 100 | |
| 101 SERVER NAME | |
| 102 | |
| 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 | |
| 237 | 106 encountered, i.e. "gvim1" for the second invocation of gvim on a particular |
| 7 | 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. | |
| 110 | |
| 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. | |
| 116 | |
| 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. | |
| 121 | |
| 122 The --serverlist argument will cause Vim to print a list of registered command | |
| 123 servers on the standard output (stdout) and exit. | |
| 124 | |
| 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". | |
| 129 | |
| 130 | |
| 131 REMOTE EDITING | |
| 132 | |
| 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 | |
| 138 editing it. | |
| 139 Note that the --remote and --remote-wait arguments will consume the rest of | |
| 237 | 140 the command line. I.e. all remaining arguments will be regarded as filenames. |
| 7 | 141 You can not put options there! |
| 142 | |
| 143 | |
| 144 FUNCTIONS | |
| 145 *E240* *E573* | |
| 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. | |
| 149 | |
| 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 | |
| 158 | |
| 159 See also the explanation of |CTRL-\_CTRL-N|. Very useful as a leading key | |
| 160 sequence. | |
| 161 The {serverid} for server2client() can be obtained with expand("<client>") | |
| 162 | |
| 163 ============================================================================== | |
| 164 2. X11 specific items *x11-clientserver* | |
| 165 *E247* *E248* *E251* *E258* *E277* | |
| 166 | |
| 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 | |
| 171 systems. | |
| 172 | |
| 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. | |
| 176 | |
| 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. | |
| 179 | |
| 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. | |
| 183 | |
| 184 An empty --servername argument will cause the command server to be disabled. | |
| 185 | |
| 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. | |
| 188 | |
| 189 ============================================================================== | |
| 190 3. Win32 specific items *w32-clientserver* | |
| 191 | |
| 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. | |
| 195 | |
| 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 | |
| 198 |ole-interface|. | |
| 199 | |
| 200 When using gvim, the --remote-wait only works properly this way: > | |
| 201 | |
| 202 start /w gvim --remote-wait file.txt | |
| 203 < | |
