| 7 | 17 An alternative is using the client-server communication |clientserver|. |
| 18 | |
| 19 ============================================================================== | |
| 20 1. Activation *ole-activation* | |
| 21 | |
| 22 Vim acts as an OLE automation server, accessible from any automation client, | |
| 236 | 23 for example, Visual Basic, Python, or Perl. The Vim application "name" (its |
| 7 | 24 "ProgID", in OLE terminology) is "Vim.Application". |
| 25 | |
| 26 Hence, in order to start a Vim instance (or connect to an already running | |
| 27 instance), code similar to the following should be used: | |
| 28 | |
| 29 [Visual Basic] > | |
| 30 Dim Vim As Object | |
| 31 Set Vim = CreateObject("Vim.Application") | |
| 32 | |
| 33 [Python] > | |
| 34 from win32com.client.dynamic import Dispatch | |
| 35 vim = Dispatch('Vim.Application') | |
| 36 | |
| 37 [Perl] > | |
| 38 use Win32::OLE; | |
| 39 $vim = new Win32::OLE 'Vim.Application'; | |
| 40 | |
| 1199 | 41 [C#] > |
| 18831 | 42 // Add a reference to Vim in your project. |
| 1199 | 43 // Choose the COM tab. |
| 11473 | 44 // Select "Vim Ole Interface 1.1 Type Library" |
| 1199 | 45 Vim.Vim vimobj = new Vim.Vim(); |
| 46 | |
| 7 | 47 Vim does not support acting as a "hidden" OLE server, like some other OLE |
| 236 | 48 Automation servers. When a client starts up an instance of Vim, that instance |
| 49 is immediately visible. Simply closing the OLE connection to the Vim instance | |
| 7 | 50 is not enough to shut down the Vim instance - it is necessary to explicitly |
| 51 execute a quit command (for example, :qa!, :wqa). | |
| 52 | |
| 53 ============================================================================== | |
| 54 2. Methods *ole-methods* | |
| 55 | |
| 56 Vim exposes four methods for use by clients. | |
| 57 | |
| 58 *ole-sendkeys* | |
| 59 SendKeys(keys) Execute a series of keys. | |
| 60 | |
| 236 | 61 This method takes a single parameter, which is a string of keystrokes. These |
| 7 | 62 keystrokes are executed exactly as if they had been types in at the keyboard. |
| 63 Special keys can be given using their <..> names, as for the right hand side | |
| 236 | 64 of a mapping. Note: Execution of the Ex "normal" command is not supported - |
| 7 | 65 see below |ole-normal|. |
| 66 | |
| 67 Examples (Visual Basic syntax) > | |
| 68 Vim.SendKeys "ihello<Esc>" | |
| 69 Vim.SendKeys "ma1GV4jy`a" | |
| 70 | |
| 236 | 71 These examples assume that Vim starts in Normal mode. To force Normal mode, |
| 7 | 72 start the key sequence with CTRL-\ CTRL-N as in > |
| 73 | |
| 74 Vim.SendKeys "<C-\><C-N>ihello<Esc>" | |
| 75 | |
| 76 CTRL-\ CTRL-N returns Vim to Normal mode, when in Insert or Command-line mode. | |
| 77 Note that this doesn't work halfway a Vim command | |
| 78 | |
| 79 *ole-eval* | |
| 80 Eval(expr) Evaluate an expression. | |
| 81 | |
| 82 This method takes a single parameter, which is an expression in Vim's normal | |
| 83 format (see |expression|). It returns a string, which is the result of | |
| 714 | 84 evaluating the expression. A |List| is turned into a string by joining the |
| 85 items and inserting line breaks. | |
| 7 | 86 |
| 87 Examples (Visual Basic syntax) > | |
| 88 Line20 = Vim.Eval("getline(20)") | |
| 89 Twelve = Vim.Eval("6 + 6") ' Note this is a STRING | |
| 90 Font = Vim.Eval("&guifont") | |
| 91 < | |
| 92 *ole-setforeground* | |
| 93 SetForeground() Make the Vim window come to the foreground | |
| 94 | |
| 95 This method takes no arguments. No value is returned. | |
| 96 | |
| 97 Example (Visual Basic syntax) > | |
| 98 Vim.SetForeground | |
| 99 < | |
| 100 | |
| 101 *ole-gethwnd* | |
| 102 GetHwnd() Return the handle of the Vim window. | |
| 103 | |
| 104 This method takes no arguments. It returns the hwnd of the main Vimwindow. | |
| 105 You can use this if you are writing something which needs to manipulate the | |
| 106 Vim window, or to track it in the z-order, etc. | |
| 107 | |
| 108 Example (Visual Basic syntax) > | |
| 109 Vim_Hwnd = Vim.GetHwnd | |
| 110 < | |
| 111 | |
| 112 ============================================================================== | |
| 113 3. The "normal" command *ole-normal* | |
| 114 | |
| 115 Due to the way Vim processes OLE Automation commands, combined with the method | |

116 of implementation of the Ex command :normal, it is not possible to execute the |
| 236 | 117 :normal command via OLE automation. Any attempt to do so will fail, probably |
| 7 | 118 harmlessly, although possibly in unpredictable ways. |
| 119 | |
| 120 There is currently no practical way to trap this situation, and users must | |
| 121 simply be aware of the limitation. | |
| 122 ============================================================================== | |
| 123 4. Registration *ole-registration* *E243* | |
| 124 | |
| 125 Before Vim will act as an OLE server, it must be registered in the system | |
| 236 | 126 registry. In order to do this, Vim should be run with a single parameter of |
| 7 | 127 "-register". |
| 128 *-register* > | |
| 129 gvim -register | |
| 130 | |
| 131 If gvim with OLE support is run and notices that no Vim OLE server has been | |
| 132 registered, it will present a dialog and offers you the choice to register by | |
| 133 clicking "Yes". | |
| 134 | |
| 135 In some situations registering is not possible. This happens when the | |
| 136 registry is not writable. If you run into this problem you need to run gvim | |
| 137 as "Administrator". | |
| 138 | |
| 236 | 139 Once vim is registered, the application path is stored in the registry. |
| 140 Before moving, deleting, or upgrading Vim, the registry entries should be | |
| 141 removed using the "-unregister" switch. | |
| 7 | 142 *-unregister* > |
| 143 gvim -unregister | |
| 144 | |
| 145 The OLE mechanism will use the first registered Vim it finds. If a Vim is | |
| 146 already running, this one will be used. If you want to have (several) Vim | |
| 147 sessions open that should not react to OLE commands, use the non-OLE version, | |
| 148 and put it in a different directory. The OLE version should then be put in a | |
| 149 directory that is not in your normal path, so that typing "gvim" will start | |
| 150 the non-OLE version. | |
| 151 | |
| 152 *-silent* | |
| 153 To avoid the message box that pops up to report the result, prepend "-silent": | |
| 154 > | |
| 155 gvim -silent -register | |
| 156 gvim -silent -unregister | |
| 157 | |
| 158 ============================================================================== | |
| 159 5. MS Visual Studio integration *MSVisualStudio* *VisVim* | |
| 160 | |
| 161 The OLE version can be used to run Vim as the editor in Microsoft Visual | |
| 162 Studio. This is called "VisVim". It is included in the archive that contains | |
| 163 the OLE version. The documentation can be found in the runtime directory, the | |
| 164 README_VisVim.txt file. | |
| 165 | |
| 36 | 166 |
| 167 Using Vim with Visual Studio .Net~ | |
| 168 | |
| 169 With .Net you no longer really need VisVim, since .Net studio has support for | |
| 170 external editors. Follow these directions: | |
| 171 | |
| 172 In .Net Studio choose from the menu Tools->External Tools... | |
| 173 Add | |
| 174 Title - Vim | |
| 175 Command - c:\vim\vim63\gvim.exe | |
| 856 | 176 Arguments - --servername VS_NET --remote-silent "+call cursor($(CurLine), $(CurCol))" $(ItemPath) |
| 36 | 177 Init Dir - Empty |
| 178 | |
| 179 Now, when you open a file in .Net, you can choose from the .Net menu: | |
| 180 Tools->Vim | |
| 181 | |
| 182 That will open the file in Vim. | |
| 183 You can then add this external command as an icon and place it anywhere you | |
| 184 like. You might also be able to set this as your default editor. | |
| 185 | |
| 186 If you refine this further, please post back to the Vim maillist so we have a | |
| 187 record of it. | |
| 188 | |
| 856 | 189 --servername VS_NET |
| 36 | 190 This will create a new instance of vim called VS_NET. So if you open multiple |
| 191 files from VS, they will use the same instance of Vim. This allows you to | |
| 192 have multiple copies of Vim running, but you can control which one has VS | |
| 193 files in it. | |
| 194 | |
| 856 | 195 --remote-silent "+call cursor(10, 27)" |
| 196 - Places the cursor on line 10 column 27 | |
| 36 | 197 In Vim > |
| 6530 | 198 :h --remote-silent for more details |
