...Dynamic pipelines
...
I'd like to be able to write the following in a flowscript:
var pipeline = flow.newPipeline("non-caching");
pipeline.setGenerator("stream");
pipeline.addTransformer("xslt", "normalize.xsl");
if (cocoon.matchers.xpath("/foo/[EMAIL PROTECTED] = '" +
cocoon.session.attributes.bar_id + "']", pipeline)) {
handleBar(pipeline);
} else {
wrongId();
}
IMHO, being able to use this stuff *outside* of Cocoon, without having to learn more than that, would make a big difference. A small facade with a clever class loader should make it possible to embed this PipelineEngine in most any java environment, not?
After all these years, the really unique thing about Cocoon is still the XML-based processing pipelines. Being able to use this as a small embeddable component would add a lot of value to our offering.
....Tell me your thoughts. Am I completely off-track,...
Again, I need more time to think about all this but I like your ideas very much.
Trying to play the devil's advocate, the questions that come to mind are a) Do we need this?If we were a company I'd ask about the return on investment: from all this, what are the two most important features or components that will bring us forward?
b) Are we able to execute this?IIUC, what you're suggesting amounts to a rewrite of large parts of Cocoon.
Problem is, it seems like very few of us are currently able to regularly dedicate significant amounts of time and energy to the development of new things here.
Starting a big "this-new-thing-is-going-to-be-so-good" project sounds very risky to me at this time, unless there's a way to do it in small steps which each bring something to our users. Or unless someone who wants it is able to commit sufficient resources to it, of course...but we know that there has to be a community behind such an effort.
... or do you also want to build this great new thing?...
I'd love to...but I'm not sure if I have a need for that in my current and envisionable projects. And the realities of life won't allow me to spend a significant part of my time on it unfortunately.
In the meantime, maybe offering an embeddable version of your "dynamic pipelines" thing would be a great help in getting more people to use the unique things that Cocoon has to offer. But it's a much smaller vision than yours ;-)
