[antlr-interest] Reading contents of file using Antlr

[mzukowski at yci.com]

Lexical nondeterminism means you have two lexical rules that are in
conflict, meaning they have the same prefix.  Post a small but complete
example which has the error message and we'll be able to help you.

Hi, 
I'm a Java programmer and relatively new to Antlr. I need to write Antlr
code to read in a text file and extract only the necessary information. How
can I go about doing that? An example of the contents of the file might look
like that : 
angle focus : 0.0005
color : blue
line width : 12
I often get the error msg:
warning : lexical nondeterminism upon ...
Also when do we use the TreeParser and what is the different between a
Parser and a TreeParser? When do we define tokens and what is it for ? Pls
help! Thanks very much.
