[Grammatica-users] Re: A doubt with the C# builder

[Per Cederberg]

¡Hola Jorge!

I'm forwarding my answer to the grammatica-users list, so
that everyone can comment on this. (Maybe someone would 
like to write a tutorial?)

I'm not currently aware of any C# tutorial or similar. 
There is no big difference in using Grammatica for C#
in comparison to Java, however. The following steps 
are required:

1. Run Grammatica in the normal way (yes, Grammatica 
   is a Java application, but can output C# source 
   code). I guess the command-line interface is most
   suitable for you (requires a modern java.exe, i.e.
   not the Microsoft version):

2. Write your own analyzer, by subclassing the one 
   generated by Grammatica (WhateverAnalyzer.cs). Only
   override the methods you are interested in. The Java
   example in the reference manual actually works, if
   you just "port" it to C# (change method names to 
   initial uppercase, remove "throws", add "override"):

3. Compile with the grammatica-1.4.dll assembly. For 
   Mono, I do like this:

   mcs -lib:./lib -reference:grammatica-1.4.dll ...

   I'm running on Linux, so I can't advise on how the
   Microsoft C# compiler works. Maybe somebody else on
   the list knows that?

If you want to see some example C# code, have a look in
the test/src/csharp/PerCederberg.Grammatica.Test 
directory. In particular, I'd recommend the 
ArithmeticCalculator.cs file (and the corresponding
arithmetic.grammar file in test/src/grammar).

Hope this helps!

Saludos,

/Pedro
