Jono,

That helped me fix my problem which was not in the compiler
finally.

Thanks for your help,

Julian

Why don't you try making a context with
AbstractSyntaxTreeUtil.generateContext()?

If that doesn't work, you'll just have to trace through it, I'm afraid...

How are you invoking it? You can't really parse sub elements individually--you need to do the whole tree starting with the programnode.

Also, you need to init it correctly, with a fresh context, etc. Hard to say without knowing how you use it.

  Problem calling the as parser directly

I am building an asdoclet (similar to java doclet) for â.asâ
files and in order to parse the â.asâ files I am calling the âmacromedia.asc.parser.Parserâ
as shown below:

private static ProgramNode
parse_asc(File file) throws IOException {

Context cx = new
Context(new ContextStatics());

    ByteArrayInputStream in =
getInputStream(file);

    cx.setScriptName(file.getName());

    cx.setPath(file.getParent());

    Parser parser = new Parser(cx,


in,


file.getAbsolutePath().replace('\\', '/'),


true, // emit doc info


true); // save comment nodes

    return parser.parseProgram();

}

The Parser can be found here:

http://opensource.adobe.com/svn/opensource/flex/sdk/trunk/modules/asc/src/java/macromedia/asc/parser/Parser.java

My problem is that everything parses fine in the SDK and my
files * except* expressions like this in a class:

public static const TOP_LEFT:int = (0x0001 | 0x0004);

The error that I get from the parser is:

        Embedded error:
bitwiseor at line â¦

Does anyone have an idea as to why I may be getting
this problem? Is there a better (cleaner) way to set up the parser to use it
externally like this?

Thanks in advance for any help you can provide.
