[antlr-interest] Code munger & Simple grammar for code generation eclipse plugin Akrogen

[Angelo zerr]

Hi,
nobody is interested by my topic?
Perhaps my explanation is very bad. If it is that, how can I do to interest
you?
Would you like more informations?

Thank you for your answers.

Regards Angelo

> With Akrogen you can update properties/XML files (by keeping user

> into java source file on the good position (into body class).

>
> To manage this case I would like execute 2 steps :
> STEP 1 : . parse Java/Javascript,... file and build XML stream which
> contains information about source file (switch grammar).
>
> Ex with this source Java class file :
>
> public class A { // <= line 1
>
>     /*
>      *
>     */
>     public void method1() { // <= line 6
>
>     } // <= line 8
> } // <= line 9
>
> After parsing (with anlr?), I would like obtain this XML stream :
>
> <sourcecode type="java">
>    <class name="A" startLine="1" endline="9" >
>       <method name="method1" startLine="6" endline="8" />
>    </class>
> </sourcecode>
>
> STEP 2 : Once the XML stream is obtained, you can use XPath to choose
> where the code (generated) must be inserted
> With XPath //class/method[last()] , you can insert generated code after
> the last method of the class.
>
> STEP2 is easy but my problem comes from STEP1 (parse source file and build
> XML stream).

>     With my test I must write the whole JAVA grammar to do that. Is it

>
> 2. I would like the user of my Eclipse plugin can add another grammar. (Ex
> : add grammar for Javascript DOJO Treeview (to add node))
>     But with antlr, grammar must be compiled to be used. Can I use grammar
> directly without compile the grammar into java class?
