Vim vs. Visual Studio
I’ve been an obsessive vi user for more than 20 years. Vi keystrokes are indelibly burned into my muscle memory. When I have to use Notepad or Word or Visual Studio, I feel crippled. I have to work harder to do simple things; I have to type too many chords with Alt and Ctrl; I have to take my hands off the home keys to use the cursor keys and the mouse.
While I was at Microsoft, I hardly ever used Visual Studio. I edited my C/C++ code with Vim, I compiled and linked it with the NT Build Environment and I debugged it with WinDbg/ntsd/kd. I was hardly alone in this. In the Windows division, your code has to build with the NT build environment, and the Windows debuggers are much better supported than the Visual Studio debugger for developing the OS.
Now that I’m programming in C#, using the Visual Studio IDE makes a lot more sense. VS’s IntelliSense for C# is much richer than Vim7’s Omni completion, especially when coupled with ReSharper, and VS is the debugger of choice for managed code. I’ve been spending a fair amount of time in the VS IDE, especially when pair programming, but I’ve also been switching back to Vim a lot. When I’m struggling with unfamiliar code, VS’s IntelliSense is a great comfort; when I’m moving a lot of text around, Vim suits me far better.
ViEmu implements most of the vi keystrokes and many of the Vim extended keystrokes, right inside the Visual Studio IDE. It uses the native VS IntelliSense in place of Vim’s completion functions. ViEmu even implements some of the more common Ex command line, including most of the :%s regular expression substitutions. The author, who seems to be known only as JNG, is responsive. Within 24-hours of my reporting some missing keystrokes, he had implemented them in a new minor release.
It does not, however, support VimL, the Vim extension language, so if you have an extensive suite of Vim plugins, as I do, they’re not going to work in ViEmu.
All in all, I’m favorably impressed with ViEmu. It provides much of the muscle memory experience of Vim inside of Visual Studio. Technically, it can’t have been easy to impose such a radically different input model on VS or to emulate Vim and Ex fairly faithfully.
Vim comes with a Visual Studio add-in called VisVim, which is based on another add-in called VisEmacs. It allows VS5 and VS6 to use Vim as the default editor, albeit externally to the IDE: Vim continues to run in its own window.
A few weeks ago, Bram asked me if I could get VisVim to compile with VS-2003. I tried, but I was unable. Necessary headers are no longer included with VS-2003 or VS-2005. No doubt this is because the Add-In architecture changed radically with the introduction of Visual Studio-.NET.
Work is underway, albeit very slowly, to create VisEmacs.NET. At some point, it may be worth creating a merger of VisVim and VisEmacs.NET.
viWord allows you to use vi keybindings in Microsoft Word. It’s not nearly as full featured as ViEmu and I found that I didn’t like it enough to keep it around.
This post was, of course, composed in Vim. I wrote it in lightly marked-up plain text and converted it to HTML with VST, Vim reStructured Text. Blogging with VST will be the topic of a future post.
