Check out this documentation topic:
.NET Languages Add-on - Visual Basic Language / Parsing and Parse Data

The last section in it talks about Grammar Options where you can change the root non-terminal. You'd want to use the DotNetGrammarRootNonTerminal.StatementList option in your case, which would allow for zero or more statements.

Sorry we don't yet have a service for supporting case auto-correct. That is something on our TODO list though, and I'll mark down your request with that item.

First the example in the documentation has this line


language.RegisterParser(New CSharpParser(grammar))

But VBSyntaxLanguage has no RegisterParser method so I used RegisterService thinking that maybe the documentation has not been updated. This is what I got:


Dim objGramOpt As New VBGrammarOptions()
objGramOpt.RootNonTerminal = DotNetGrammarRootNonTerminal.Expression

Dim objLang As New VBSyntaxLanguage()
objLang.RegisterService(New VBParser(New VBGrammar(objGramOpt)))

SyntaxEditor.Document.Language = objLang
SyntaxEditor.Text = String.Format("For x = 1 To 5{0}{1}x = 2{0}Next ", vbCrLf, vbTab)

However I still get the error.

RegisterParser is an extension method that comes in if you import the ActiproSoftware.Text namespace. We'll add a note on that. If you don't do that, you still need to change your code to register the service as type IParser or else it won't be used. Our code looks for a service registered as an IParser. To do this, do something like:

objLang.RegisterService(Of IParser)(New VBParser(New VBGrammar(objGramOpt)))

Also you specified the wrong root non-terminal option (Expression). You want StatementList per our previous reply.

Got the "StatementList" option to work except it fails the syntax check with error "document end expected" in this code:


For x = 1 to 5
Next

Dim a as string 'error occurs on the Dim but only if there is a blank line above it

I also have another code window that hosts the contents of a hidden class. For example:


'hidden glue code
Public Shared Class GlobalFunctions

'nothing above this line is shown in edit box

    'here a user can enter a Sub, Function, or Class definition
    Public Shared Sub MySubName()
        'user code
    End Sub

    Public Shared Function MyFuncName() as Object
        'user code
    End Function

    Public Class MyClassName
        'user code
    End Class

'nothing below this line is shown in edit box

End Class
'hidden glue code

I tried all the other DotNetGrammarRootNonTerminal members and none fit this scenario. They all complain of syntax errors.

Thanks for the sample, it appears there is a bug in the VB grammar's StatementListRoot non-terminal where it doesn't currently allow empty lines between statements. We've fixed it for the next maintenance release. Your first snippet in the previous post will work fine with that change.

Just a quick FYI... per this blog post, auto-case correct is coming in the next 2013.1 maintenance release:
