[Flow] Importing multiple scripts? (ScriptDirectoryNode)

Hi Cocoon developers,

is it currently possible to include a set of scripts
dynamically? I imagine something like a
o.a.c.c.treeprocessor.sitemap.ScriptDirectoryNode
that works similar to the DirectoryGenerator by
gathering all .js files in a certain directory tree.

Or is there another way to achieve this functionality?

At least the XInclude spec knows an "include text" mode. It seems our our
implementation suports it:

if (parse.equals("text")) {
  getLogger().debug("Parse type is text");
  InputStream input = url.getInputStream();
  Reader reader = new BufferedReader(new InputStreamReader(input));
  int read;
  char ary[] = new char[1024];
  if (reader != null) {
    while ((read = reader.read(ary)) != -1) {
      super.characters(ary,0,read);
    }
    reader.close();
  }
} else if (parse.equals("xml")) {
  ...
}

This would make a text parser superfluous.

And what about CInclude? Does it also know a text mode?

This one is probably useful for this purpose.
I'll try to use it.

Thanks!

I'm nearly sure it won't work. The DirectoryGenerator itself does not include
any file, the XPathDirectoryGenerator expects XML files:

source = resolver.resolveURI(xmlFile.toURL().toExternalForm());
this.doc = this.parser.parseDocument(SourceUtil.getInputSource(source));

Note that there are at least two ways to "XMLize" text files:

-The chaperon block TextGenerator, which puts the whole text in a 
single element

-The slop block SlopGenerator, which creates one element for each input 
line

I would use CInclude. I'll try if it includes text files
and complain if it doesn't work :)

Thanks again!

embedding Javascript in XML is IMHO ugly but it would work this way.
Does the directory generator read a all files including their content or
do you use the cinclude transformer? If so and it doesn't accept non-xml
content it should be patched.

OK. So I have to write scripts included in XML, aggregate
them using the DirectoryGenerator, strip the XML tags and
serialize as text?

You can dynamically add scripts using

 <map:flow>
   <map:script src="cocoon://bla"/>
 </map:flow>

So you can use the DirectoryGenerator but be aware of possible conflicts
by using the same function or global variable names.
