Question

What is the easiest way to programmatically force capitalization of keywords in Visual Studio 2008?

We work with a proprietary command delimited language (like HTML). We are attempting to migrate from an older editor to Visual Studio 2008. Our coding standards are to capitalize the commands. The old editor is customized to recognize the command begin delimiter and to force capitalization until the end delimiter is typed or the escape key is pressed.

What’s the best way to do that in Visual Studio 2008? Can it be done with a macro or an add-in?

Thank you for the suggestions so far. I don’t think they answer my question.

Clarifications:

• The previous editor was CodeWright so the customizations there are not portable to visual studio.
• The source code is not C#. StyleCop seems to be specifically for C#. Our language is similar to markup languages like HTML but with different delimiter characters and commands.
• I am trying to actually capitalize as the developer types, not remind them about proper capitalization. Since the commands are all delimited our current editor actually turns the Caps Lock on when the beginning delimiter is typed. When the end delimiter or the escape key is pressed the caps lock is turned back off. This is independent of the state of the Caps Lock on the keyboard.

This may not be the best solution but here is what I came up with.

Use macros to capture Key Press Events.

Here’s how:

1. In Visual Studio go to the Tools->Macros->Macros IDE menu
2. Double Click ‘MyMacros’ to see the different parts
3. Double Click ‘EnvironmentEvents’
4. Add the following code within the Environment Events module.

5. Save the file and return to the regular VS IDE to test.

   Private My_AutoCaps As Boolean = False Private Sub TextDocumentKeyPressEvents_BeforeKeyPress(ByVal Keypress _   As String, ByVal Selection As EnvDTE.TextSelection, _   ByVal InStatementCompletion As Boolean, ByRef CancelKeyPress As Boolean) _   Handles TextDocumentKeyPressEvents.BeforeKeyPress      Dim fileName As String = UCase(Selection.DTE.ActiveDocument.Name)      If ( fileName.EndsWith('.CPI') ) Then          If (My_AutoCaps) Then              'MsgBox(Keypress)              If (Keypress = '(' Or Keypress = ':') Then                  'MsgBox('End of command character pressed.')                  My_AutoCaps = False                  Return              ElseIf (Keypress >= 'a' And Keypress <= 'z') Then                  'MsgBox('Letter pressed.')                  Selection.Text = UCase(Keypress)                  CancelKeyPress = True              End If          Else 'AutoCap is not on yet              If (Keypress = '^') Then                  'MsgBox('You pressed the Start Command character.')                  My_AutoCaps = True                  Return              End If          End If      End If End Sub 

This macro is limited to *.CPI files.

I have not figured out how to capture the Esc key yet but this will work for now.
