[antlr-interest] Problem with integrating ANTLR with XAML

[Sam Harwell]

A few more questions:

Did you follow the instructions in the Documentation section here? In
particular, can you verify that sections 1.4 and 2.1 were incorporated
correctly?
http://www.antlr.org/wiki/display/ANTLR3/Antlr3CSharpReleases

Are you using the 3.4.1.9004 release of the C# port of ANTLR 3?

Did you make any changes to the .targets file from the one included in the
Releases listed on that page?

Thanks,

Hi Sam:

I don't try to reference FormulaLexer or FormulaParser in the XAML file, but
I need some of the other classes in the FormulaPlotter namespace in the
XAML. I've tried putting the ANTLR stuff in a different namespace from the
MainWindow stuff, but it doesn't help.
I've also tried putting the C# code that references the ANTLR stuff in a
separate namespace from MainWindow but that didn't help either.

Basically, the program has a DataGrid which is data-bound to a DataTable, in
which I store the strings representing the formulas to be plotted and the
colour of the plot line and so on. The user enters the formula and colour in
the DataGrid in the GUI and these are connected to the DataTable via data
binding.
So I'd like to be able to refer to the DataTable in the XAML in order to
bind some of the display properties to entries in the DataTable.

The errors cause the build to fail. I know that sometimes ANTLR will show
errors in the errors window which go away when you do a build, but these
errors are 'real'
errors
that cause a build fail.
