How to ignore white space when comparing source in

问题:

The compare tool in Visual Source Safe (pre TFS) had a handy checkbox to select "Ignore White Space".

Now we are using TFS with Visual Studio 2010, and the compare dialog no longer has this option. (A ridiculous oversight from Microsoft!)

So, is it possible somehow to work around this?

回答1:

This is a workaround that seems to get around the problem.

In Visual Studio, select Tools / Options / Source Control / Visual Studio Team Foundation System and click the Configure User Tools button.

In the dialog, Add an item with the following settings.

• Extension : .*
• Operation : Compare
• Command : C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\diffmerge.exe
• Arguments : %1 %2 %6 %7 %5 /ignorespace

---

Edit:

Depending on your Visual Studio version and instalation path (x64/x86), the command option may be...

VS2010: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\diffmerge.exe
VS2012: C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\diffmerge.exe
VS2013: C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\vsDiffMerge.exe
VS2015: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\vsDiffMerge.exe
VS2017: C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\CommonExtensions\Microsoft\TeamFoundation\Team Explorer\vsDiffMerge.exe

In the argument option leave it with the same number of arguments as the VS suggests and just add /ignorespace in the end. For example, in the VS2015 it will be:

%1 %2 /ignorespace

There is a "=" button on Visual Studio 2017 toolbar that helps to compare files as you want. Hope this screenshot will help.

The default diff tool in Visual Studio is extremely annoying. I suggest you use an alternative. WinMerge is my favourite. It also has an option to ignore whitespace (menu Edit -> Options -> Compare -> Ignore all (under the groupbox "Whitespace" at the top)).

See Using WinMerge with TFS.

In VS2015 it's possible to "ignore white space" when comparing clicking a little icon with the = symbol.
Go to "View/Toolbars/Compare Files". In the toolbar click on "Ignore trim whitespace".

回答5:

in VS 2012, this might be what you're looking for with no changes to Diff tool.

Opening up the compare screen in VS 2012 and at the top you see the following option in the toolbar. as it might be the same comparison as user: Master screenshot.

The default diff tool in VS 2013 does let you ignore whitespace after all. Just run the standard differencing process. When Visual Studio brings up the differences, look on the toolbar, where you will see an icon that looks like a document with 5 dots under it, as shown below. This button toggles whether the displayed differences ignore white space. This worked well enough for me; I wanted it to ignore changes in the white space caused by indentation.
