    copied!<p>I am investigating using TFS 2012 as the Source Control provider for Matlab, on Windows 7. This requires installing the VS 2012 shell/TFS client, and the 64-bit MSSCCI provider available as free downloads from Microsoft. I've set all this up and it works OK.</p> <p>However, there is a problem with file differencing and merging. If I view differences from VS 2012 Source Control Explorer, the VS 2012 Diff tool runs correctly. If I try the same operation from within Matlab (using the Source Control menu) I get an error "Cannot Execute the Configured Tool". The same thing happens with the 'merge changes in merge tool' button when resolving conflicts: in VS 2012 it works, from Matlab, it doesn't.</p> <p>It appears this is a known problem, at least with other tools trying to drive TFS. There is a work-around, which is to configure VS 2012 to use an external differencing utilty. I tried this and it worked. Furthermore, I found that if you configure the external differencing utility to be VS 2012's own 'internal' diff tool, the internal tool will be correctly called from Matlab.</p> <p>The diff command is:</p> <pre><code>C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe </code></pre> <p>and the required arguments are:</p> <pre><code> /Diff %1 %2 %6 %7 </code></pre> <p>(i.e. original file, modified file, original file label, modified file label). There is documentation on this <a href="http://msdn.microsoft.com/en-us/library/vstudio/jj874068.aspx" rel="nofollow">here</a>.</p> <p>The merge tool is more problematic. I can't find any specific documentation on its command line. The closest I've got so far is</p> <pre><code>C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\vsDiffMerge.exe </code></pre> <p>which I'm pretty certain is right, but the arguments I'm using</p> <pre><code>%1 %2 %1 %2 %3 %4 /m </code></pre> <p>are not quite right - the file labels are different, and the difference display is formatted differently (from the normal built-in tool). I reverse-engineered this command line from some git-related documentation <a href="http://social.technet.microsoft.com/wiki/contents/articles/17905.conflitti-durante-lo-sviluppo-concorrente-it-it.aspx" rel="nofollow">here</a> but I don't know anything about git, nor do I speak Italian. Can anybody help me find the correct command line options to use, please?</p> <p><strong>EDIT TO ADD</strong></p> <p>There is an MSDN Discussion which seems to be related to this problem <a href="http://visualstudiogallery.msdn.microsoft.com/b1ef7eb2-e084-4cb8-9bc7-06c3bad9148f/view/Discussions" rel="nofollow">here</a>. It looks like it happens with other tools and is not limited to Matlab: I've re-tagged this question accordingly</p> <p><strong>EDIT TO ADD</strong></p> <p>The preferred command-line for the Diff functionality is:</p> <pre><code>C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\vsDiffMerge.exe </code></pre> <p>and the command-line arguments are:</p> <pre><code>/t %1 %2 %6 %7 </code></pre> <p>The equivalent for the Merge functionality does not work: this is an internal bug &amp; Microsoft have acknowledged this.</p>
