[antlr-interest] Problem with integrating ANTLR with XAML

[Glenn Rowe (Orders)]

I'm relatively new to ANTLR and as a test I wrote a sample program that uses
ANTLR to define a grammar that allows

mathematical expressions such as x^2 + 4*x*cos(x) to be entered and then
have a graph of the function drawn.

The program is written in C# using WPF and XAML to define the layout, and
uses the ANTLR3 plugin for Visual Studio 2010.

 

Everything works fine unless I try to define an xmlns namespace alias for
the local namespace in which the program's code is written

in MainWindow.xaml. That is, I add the line

 

xmlns:local="clr-namespace:FormulaPlotter"

 

to the Window tag at the start of the XAML file, where FormulaPlotter is the
namespace of my code. Doing this generates 8

errors of the sort 

 

FormulaLexer does not have a constructor with 1 argument (although it does)

start() method not found

 

and other errors complaining about constructors or methods in the lexer or
parser not being found.

 

The only workaround I have found for this is to write the relevant bits of
the program in the C# code-behind file,

which is quite awkward for some of the stuff I want to do.

 

Does anyone know of a fix for this problem?

Thanks.

Glenn.
