The ProvideLanguageServiceAttribute class has been with us for many years now. At least since it shipped as source code in the Visual Studio 2005 SDK. With more than two dozen properties, it’s easy to get lost trying to figure out which ones are meaningful and/or useful, and which ones are safe to ignore.
The Visual Studio 2010 SDK introduced the new class FileExtensionToContentTypeDefinition. This post is all about why I no longer use/export this class, and what I now do instead. The steps in this post only associate specific, known extension(s) with a content type. Further integration into the user-customizable File Types settings and Open With… features requires […]
Tunnel Vision Labs is currently working on extending the Java Language Support extension for Visual Studio to include a complete source-level debugger. If you are interested in testing an alpha build of this debugger, please contact Tunnel Vision Labs for more information. In this post, I’ll talk a bit about the current state of the […]
This post is derived from an email I sent to the NetBeans mailing last month. Some of the implementation details refer to specific items in the NetBeans codebase, but the general algorithms apply to any number of applications. In the past I alluded to spending a great deal of time thinking about ways to improve […]
I’ve been working on Visual Studio 2010 extensibility for some time now, and I must say that creating a tool window was not the easiest task in the world. First Attempt: Create an MEF-friendly IToolWindowService The original goal of this project was creating an MEF service that allowed exporting classes implementing IToolWindowProvider, and have the […]
I originally sent this to the ANTLR interest group, but figured it would make for a decent post here as well. I’ll start with a couple fundamental concepts. First, there are three key things that get parsed in an IDE: The syntax highlighter lexes the current document. Files that are not opened in the editor. […]
As some people have noticed, the Visual Studio 2010 SDK doesn’t have great support for the Output Window from MEF extensions. This post aims to change that. Like several other components I’m writing about, I hope to provide this one in a “general extensibility helper” that could be installed separately from extensions that use it […]
I haven’t perfected it yet, but here is a fairly general brace matching tagger that seems to work very well. It relies on the classifier for the content type properly tagging comments and literals with classification types derived from PredefinedClassificationTypeNames.Comment and PredefinedClassificationTypeNames.Literal, which any decent classifier will do. This example really shows a big improvement […]
I’ve been experimenting with Visual Studio’s new extensibility model, and ran into a problem with squiggles. It seems that despite having an internal IQuickInfoSource for the SquiggleTag and IUrlTag, it’s not hooked up to a IIntellisenseController so it never appears. Here is a general implementation for an SquiggleQuickInfoIntellisenseController and UrlQuickInfoIntellisenseController that will provide QuickInfo for […]
By default, brace matching is performed in response to the left and right arrow keys. It should be done in response to several additional commands, as shown below.
