SableCC in a C# desktop application

[MatthiasVanneste]

Hi all,

I've just discovered SableCC and I would like to use it in a C# desktop application. I've used the C# output module by Indrek Mandre. I'm using the demo grammar and translator code used in the thesis to mess around with. What I'm trying is this :

//Main Code//

TextReader txtReader = new StreamReader(ofdSource.OpenFile());

String file = "";

Parser p = new Parser(new Lexer(txtReader));

Start tree = p.Parse();

translation tr = new translation(ref file);

tree.Apply(tr);

txtTarget.Text = "...Finished";

//End Main Code//

//Translator Code//

public class translation : DepthFirstAdapter
{
        private String file;

        public translation(ref string f)
        {
            file = f;
        }

        public void caseTNumber(TNumber node)
         {
             file.Insert(file.Length, node.Text + "\n");
         }
}

//End Translator Code//

My aim is for the translator to, when encountering a number, to write it to the provided string.
Unfortunately, it seems as the translator methods are not being called at all. I don't know if it can even work like this? If anyone has any tips or advise I would appreciate to get it.

Thx.

Greetings,

Matt.

This is the fragment we use:

StringReader reader = new StringReader( input );

Lexer l = new Lexer(reader);
Parser p = new Parser(l);
Start ast = p.Parse();

ast.Apply(new TreeWalker());


It doesn't seem different from yours.


Have you looked at the lexer output to verify that your language is
generating a TNumber token when you expect it to?

Hi!

The problem you have here is the name of the case method.
It should probably be "CaseTNumber" - it uses the C# Camel
Casing style for naming members with first letter capital
as well. See the generated analysis.cs file for prototypes.

Indrek

I've been checking the AST and it is correct, I used a very simple example (15 * 3).
But I can't seem to make it call the outAFactorExpr(AFactorExpr node) method.

It's OutAFactorExpr (capital 'O'). Check the analysis.cs for prototypes.

Hmm, that's weird. According to Microsoft, Camel Case is what he has there ( caseWhatever ), and what he should have is Pascal Case ( CaseWhatever ). Wikipedia has the opposite opinion on what the meaning of Camel Case is ( CaseWhatever ). Confusing.

Nice to see you're still out there Indrek.

I'm a tad confused about this as well.

According to wikipedia:
http://en.wikipedia.org/wiki/Identifier_naming_convention#Microsoft.27s_.NET
or
http://msdn.microsoft.com/en-us/library/x2dbyw72(VS.71).aspx
Quote: '''Microsoft .NET recommends upper camel case
(aka "Pascal Style") for most identifiers. (lower camel case is
recommended for parameters)'''

I don't really like camel case myself (either lower or upper camel)
but as microsoft recommended it and all of the .NET API-s use it,
I went with the upper camel (or oh well, lets call it Pascal Case
to clear any confusion for the future).

Regards,
Indrek

The best way to minimize confusion is to call it UpperCamelCase and
lowerCamelCase. ;)
