Unless this is a one-person project, don't do it. It's got to be trivial to diff your local files against your source code repository, and clearing whitespace would change lines you don't need to change. I totally understand; I love to get my whitespace all uniform – but this is something you should give up for the sake of cleaner collaboration.

You can create a macro that executes after a save to do this for you.

Add the following into the EnvironmentEvents Module for your macros.

<pre><code>Private saved As Boolean = False
Private Sub DocumentEvents_DocumentSaved(ByVal document As EnvDTE.Document) _
 Handles DocumentEvents.DocumentSaved
 If Not saved Then
 Try
 DTE.Find.FindReplace(vsFindAction.vsFindActionReplaceAll, _

 saved = True
 document.Save()
 Catch ex As Exception
 MsgBox(ex.Message, MsgBoxStyle.OkOnly, "Trim White Space exception")
 End Try
 Else
 saved = False

End Sub
</code></pre>

I've been using this for some time now without any problems. I didn't create the macro, but modified it from the one in ace_guidelines.vsmacros which can be found with a quick google search.

This is a really good example of how to remove trailing whitespace. There are a few things that I would change based on what I discovered using this macro. First of all, the macro automatically converts tabs to spaces. This is not always desirable and could lead to making things worse for people that love tabs (typically Linux-based). The tab problem is not really the same as the extra whitespace problem anyways.
Secondly, the macro assumes only one file is being saved at once. If you save multiple files at once, it will not correctly remove the whitespace. The reason is simple. The current document is considered the document you can see.
Third, it does no error checking on the find results. These results can give better intelligence about what to do next. For example, if no whitespace is found and replaced, there is no need to save the file again. In general, I did not like the need for the global flag for being saved or not. It tends to ask for trouble based on unknown states. I suspect the flag had been added solely to prevent an infinite loop.

<pre><code> Private Sub DocumentEvents_DocumentSaved(ByVal document As EnvDTE.Document) _
 Handles DocumentEvents.DocumentSaved
 Dim result As vsFindResult
 'Dim nameresult As String

 Try
 document.Activate()

 ' Remove all the trailing whitespaces.
 result = DTE.Find.FindReplace(vsFindAction.vsFindActionReplaceAll, _
 ":Zs+$", _
 vsFindOptions.vsFindOptionsRegularExpression, _
 String.Empty, _
 vsFindTarget.vsFindTargetCurrentDocument, , , _
 vsFindResultsLocation.vsFindResultsNone)

 'nameresult = document.Name &amp; " " &amp; Str$(result)

 'MsgBox(nameresult, , "Filename and result")

 If result = vsFindResult.vsFindResultReplaced Then
 'MsgBox("Document Saved", MsgBoxStyle.OkOnly, "Saved Macro")
 document.Save()
 Else
 'MsgBox("Document Not Saved", MsgBoxStyle.OkOnly, "Saved Macro")
 End If

 Catch ex As Exception
 MsgBox(ex.Message, MsgBoxStyle.OkOnly, "Trim White Space exception")
 End Try

End Sub
</code></pre>

I added debug message boxes to help see what was going on. It made it very clear that multiple file save was not working. If you want to play with them, uncomment those lines.

The key difference is using document.Activate() to force the document into the foreground active current document. If the result is 4, that means that the text was replaced. Zero means nothing happened. You will see two saves for every file. The first will replace and the second will do nothing. Potentially there could be trouble if the save cannot write the file but hopefully this event will not get called if that happens.

Before the original script, I was unaware of how the scripting worked in Visual Studio. It is slightly surprising that it uses Visual Basic as the main interface but it works just fine for what it needs to do.

blocks|key|1544634|text|一个简单的添加是在保存期间删除回车符。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1544635|'+Remove+all+the+carriage+returns.

A simple addition is to remove carriage returns during the save. 

<pre><code>' Remove all the carriage returns.
result = DTE.Find.FindReplace(vsFindAction.vsFindActionReplaceAll, _
 "\x000d\x000a", _
 vsFindOptions.vsFindOptionsRegularExpression, _
 "\x000a", _
 vsFindTarget.vsFindTargetCurrentDocument, , , _
 vsFindResultsLocation.vsFindResultsNone)
</code></pre>

The key to this working is changing \x000d\x000a to \x000a. The \x prefix indicates a Unicode pattern. This will automate the process of getting source files ready for Linux systems.

Building on Dyaus's answer and a regular expression from a <a href="http://connect.microsoft.com/VisualStudio/feedback/details/386050/delete-trailing-white-spaces" rel="nofollow noreferrer">connect report</a>, here's a macro that handles save all, doesn't replace tabs with spaces, and doesn't require a static variable. Its possible downside? It seems a little slow, perhaps due to multiple calls to <code>FindReplace</code>.

<pre><code>Private Sub DocumentEvents_DocumentSaved(ByVal document As EnvDTE.Document) _
 Handles DocumentEvents.DocumentSaved
 Try
 ' Remove all the trailing whitespaces.
 If vsFindResult.vsFindResultReplaced = DTE.Find.FindReplace(vsFindAction.vsFindActionReplaceAll, _
 "{:b}+$", _
 vsFindOptions.vsFindOptionsRegularExpression, _
 String.Empty, _
 vsFindTarget.vsFindTargetFiles, _
 document.FullName, , _
 vsFindResultsLocation.vsFindResultsNone) Then
 document.Save()
 End If
 Catch ex As Exception
 MsgBox(ex.Message, MsgBoxStyle.OkOnly, "Trim White Space exception")
 End Try
End Sub
</code></pre>

For anyone else trying to use this in a Visual Studio 2012 add-in, the regular expression I ended up using is <code>[ \t]+(?=\r?$)</code> (don't forget to escape the backslashes if necessary). I arrived here after several futile attempts to fix the problems with a <a href="http://msdn.microsoft.com/en-us/library/vstudio/2k3te2cs.aspx" rel="nofollow noreferrer">raw conversion</a> of <code>{:b}+$</code> failing to match the carriage return.

Is it possible to configure Visual Studio 2008 to automatically remove whitespace characters at the end of each line when saving a file? There doesn't seem to be a built-in option, so are there any extensions available to do this?

How to automatically remove trailing whitespace in Visual Studio 2008?

Visual Studio

是否可以将Visual Studio 2008配置为在保存文件时自动删除每行末尾的空格字符？似乎没有内置的选项，那么有没有扩展可以做到这一点呢？
