Edited by Bram Moolenaar. + + +INSTALLATION + +To install the "Edit with Vim" popup menu entry, it is recommended to use the +"install.exe" program. It will ask you a few questions and install the needed +registry entries. + +In special situations you might want to make changes by hand. Check these +items: +- The gvimext.dll, gvim.exe and uninstal.exe either need to be in the search + path, or you have to set the full path in the registry entries. You could + move the gvimext.dll to the "windows\system" or "windows\system32" + directory, where the other DLL files are. +- You can find the names of the used registry entries in the file + "GvimExt.reg". You can edit this file to add the paths. To install the + registry entries, right-click the gvimext.reg file and choose the "merge" + menu option. +- The registry key [HKEY_LOCAL_MACHINE\Software\Vim\Gvim] is used by the + gvimext.dll. The value "path" specifies the location of "gvim.exe". If + gvim.exe is in the search path, the path can be omitted. The value "lang" + can be used to set the language, for example "de" for German. If "lang" is + omitted, the language set for Windows will be used. + +It is the preferred method to keep gvim.exe with the runtime files, so that +Vim will find them (also the translated menu items are there). + + +UNINSTALLATION + +To uninstall the "Edit with Vim" popup menu entry, it is recommended to use +the "uninstal.exe" program. + +In special situations you might want to uninstall by hand: +- Open the registry by running regedit.exe. +- Delete all the keys listed in GvimExt.reg, except this one: + [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved] + For this key, only delete one value: + "{51EEE242-AD87-11d3-9C1E-0090278BBD99}"="Vim Shell Extension" +- Delete the gvimext.dll, if you want. You might need to reboot the machine + in order to remove this file. A quick way is to log off and re-login. + +Another method is by using the uninst.bat script: + uninst gvimext.inf +This batch file will remove all the registry keys from the system. Then you +can remove the gvimext.dll file. +Note: In order for this batch file to work, you must have two system files: +rundll32.exe and setupapi.dll. I believe you will have rundll32.exe in your +system. I know windows nt 4.0 with the service pack 4 has setupapi.dll. My +windows 95 has setupapi.dll. I find that the internet explorer 4.0 comes with +the setupapi.dll in file Ie4_5.cab. + +If you do encounter problems running this script, then probably you need to +modify the uninst.bat to suit to your system. Basically, you must find out +where are the locations for your rundll32.exe and setupapi.dll files. In +windows nt, both files are under c:\winnt\system32 directory. In my windows 95 +system, I got setupapi.dll at c:\windows\system and rundll32.exe at +c:\windows. So you might want to try something like: + rundll32.exe c:\windows\system\setupapi.dll,InstallHinfSection DefaultUninstall 128 %1 +where %1 can be substitued by gvimext.inf + + +THE SOURCE CODE + +I have provided the source code here in hope that gvim users around world can +further enhance this little dll. I believe the only thing you need to change +is gvimext.cpp file. The important two functions you need to look at are +QueryContextMenu and InvokeCommand. You can modify right-click menus in the +QueryContextMenu function and invoke gvim in the InvokeCommand function. Note +the selected files can be accessed from the DragQueryFile function. I am not +familiar with the invoking options for gvim. I believe there are some +improvements that can be made on that side. + +I use MS Visual C++ 6.0's nmake to make the gvimext.dll. I don't have a +chance to try earlier versions of MSVC. The files that are required for build +are: + gvimext.cpp + gvimext.h + gvimext.def + gvimext.rc + resource.h + Makefile + +To compile the DLL from the command line: + vcvars32 + nmake -f Makefile + +If you did something interesting to this dll, please let me know +@ tianmiao@acm.org. + +Happy vimming!!! diff --git a/src/GvimExt/gvimext.cpp b/src/GvimExt/gvimext.cpp new file mode 100644 index 0000000000..57fbf81199 --- /dev/null +++ b/src/GvimExt/gvimext.cpp @@ -0,0 +1,979 @@ +/* vi:set ts=8 sts=4 sw=4: + * + * VIM - Vi IMproved gvimext by Tianmiao Hu + * + * Do ":help uganda" in Vim to read copying and usage conditions. + * Do ":help credits" in Vim to see a list of people who contributed. + */ + +/* + * gvimext is a DLL which is used for the "Edit with Vim" context menu + * extension.
