Code Metrics Power Tool 11.0

Some weeks ago, Microsoft released the Code Metrics Power Tool 11.0 that works together with the latest FxCop binaries of Visual Studio 2012. What a surprise… I did not expect that they would come up with a new version of the tool, due to the fact that the code metrics analysis feature is now also available in Visual Studio Professional (of course I know it´s intended to be used in an automated build environment). Even though I implemented my own metrics calculator based on the Roslyn September 2012 CTP, I will integrate the Power Tool into the Code Metrics Viewer 2… thinking about to move the experimental Roslyn stuff into a separate package. Will see…

For god´s sake! I would like to know why the Power Tool does not have a user-friendly setup? It is compressed into a self-extracting cabinet file. In my opinion, this would be okay, if the package would also contain all dependencies which are required to run the application. This would allow to install it to a directory free of choice. But no, the Metrics.exe binary is tightly coupled to Visual Studio binaries and must be copied to the FxCop directory within the Visual Studio installation folder (at least this is mentioned in the installation instructions on the download page). So, before I do the integration, I need to think about a setup util…

I wrote some sample code that can be used to build a simple setup application: http://bit.ly/10kQMQj

Update, 2013/09/20: The Code Metrics Viewer 2012 extension is now available at http://bit.ly/19kOHUI.

Code Metrics Viewer 2 CTP

I published a pre-release version of the Code Metrics Viewer 2 extension targeting Visual Studio 2012. It´s the continuation of my first contribution, but it works completely different. The first version was just a user-interface that integrated the Code Metrics Power-Tool 10.0 into the development environment, but the new version brings its own calculation functionality – and instead of analyzing IL it acts on the source code. The current release supports metric calculation for C#-projects, but functionality supporting Visual Basic is on schedule.

The extension is dependent on the Microsoft “Roslyn” CTP (September 2012, v1.2), which need to be downloaded and installed separately. Because I wasn´t sure, if I am allowed to distribute the Roslyn binaries, I decided to exclude them from the extension package and defined a dependency to the Roslyn Components instead. The Extension Manager will show the following dialog to you if the required package dependency is missing.

The download can be found at the Visual Studio Developer Center: http://bit.ly/YujBX8 or on NuGet: http://bit.ly/WheTeO. If the components will be removed after installing the extension, calculation of metric results isn´t possible and the following error message will be shown: “The calculation of metric results has failed. Couldn´t find the Roslyn CTP components.”

Currently no support of VS2012

Due to the fact that the current version of the Power Tool is not compatible with Visual Studio 2012, there won´t be an upgrade for the Code Metrics Viewer extension. There is a suggestion on Microsoft´s user voice portal to either open up the code metrics calculation interface or to provide a new version of the command line utility, that is not dependent on Visual Studio 2010. Using the following link you can vote for it: http://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/3014740-please-update-visual-studio-metrics-power-tool-to

Update, 2013/01/7: I just used some time to play with the Roslyn CTP and created a tool that can calculate metrics from syntax trees and semantic models (in the strict sense a replacement for the Power Tool, that does not act on IL, but on source code). By now, I can calculate the same metric results provided by the Power Tool for C# projects and I also added some new metrics.

Update, 2013/01/14: I started to make the extension available to Visual Studio 2012; I just ported the existing code base and removed everything related to Microsoft´s power tool, that can´t be used anymore. The tool window get´s a complete make-over supporting both the dark- and light theme. Maybe I have to replace functionality which is dependent on Windows Forms by using WPF, but I don´t know yet. The toolbar is now a native toolbar, that fits much better into the selected theme. As long as Roslyn isn´t ready-to-market, this extension will be a CTP as well, that requires an existing installation of the Roslyn components.

Update, 2013/01/16: A first look at the new UI…

Update, 2013/01/25: I worked a lot on the user-interface… Instead of reusing the existing win-forms tree-listview implementation from the previous version, I decided to create a tree-listview using WPF. I am quite familiar with WPF, so I thought the hardest part of the entire project would be the implementation of the actual metric calculation functionality (which I have achieved within a couple of hours), but in the end I used more time to style the WPF listview (thanks a lot to a Swedish friend of mine, who helped me to solve some very tricky issues and polish it). It was well worth investing the time because the new control allows scrolling horizontally, the scrollbars are themed automatically, the positioning of grid columns is now supported and I was able to remove some code that required P-Invoke (think this is a step in the right direction).

Update, 2013-01-27: I spiled Visual Studio´s glyph-service to show icons in the results view…

Update, 2013-02-02: The extension is almost feature-complete; I am working on some details now. For instance, the new version of the tool doesn´t show a progress dialog anymore. Instead, it has a thin progress indicator that is embedded into the view (so it behaves the same way as many other tool windows in Visual Studio do).

I reworked the trend icons (up- and down-arrows) and used the color´s of Visual Studio´s light theme so I can switch luminosity depending on the selected theme, to make them look good…
