Unexpected error in VB.Net Syntax Editor. - SyntaxEditor .NET Languages Add-on for WPF Forum

Platform: .NET 4.0

Environment: Windows 7 (64-bit)

Hi,

We are using actipro syntax editor's VB.Net addon in our product. Recently I found that the editor complains about a valid piece of code. Here is the code,

Sub Count
Static Dim tmp As Boolean
tmp = Not tmp
End Sub

The editor throws an error, "Identifier expected", while the same code compiles in Visual Studio 2013 /2010 without any issue. I am not a VB.net developer, however, I understood from some VB.Net forums that Dim is optional in this context.

Is this is a bug or expected behaviour?

Thanks,

Ram.

Hi Streeram,

According to the VB 10 official specification, a local modifier (part of a local variable declaration statement) is defined as:

LocalDeclarationStatement  ::=  LocalModifier  VariableDeclarators  StatementTerminator
LocalModifier  ::=  Static  |  Dim  |  Const

You can see there by the EBNF that only a single one of those modifiers is allowed. Fields (variables defined outside of a Sub) do however allow multiple modifiers. But per the spec, our grammar is coded correctly.
