Re: Cocoon Productivity
As a new adopter of cocoon, I beg to differ from some of what I have read regarding documentation. Referring to cocoon version 2.1, it comes with lots and lots docs and examples. I really do not think we are dealing with a lack of documentation or examples. Rather it's a case of knocking what already exists into shape. Especially the examples. IMHO the examples need to be "rewritten" so that they function at two levels. Firstly, they should be shiny examples of cocoon functionality when played with via the browser. Secondly, each example should be totally standalone in its own sitemap, suitable for lifting from cocoon distribution and used as a template for new users getting started with cocoon. Individually the examples do fine at the first point, although cumulatively they are a rather disorganised mish-mash. At the second level it is a significant task for a new user to disentangle a demo application, that almost does what they need, from other related demos that share sitemaps, resources and other dependencies. I also suspect that a number of examples reflect practices which are now deprecated. Deprecated examples should be removed, there's nothing worse than getting your head around one method only to be told it's a dead technique and something else should be used instead. The coverage of documentation is patchy, some bits are quite well covered other bits rather poorly. When it is good it is very good. The general overviews, concepts and simple stuff is fine, but the detail of serializers, generators, generators and actions etc is where major problems really start to appear. Far to vague and in some cases unintuitive. I have not seen anyone else pointing it out, but after a day or two I was really struck by the fact that conceptually pipelines are not pipelines in any common understanding of the term; rather matchers are the pipelines! This sort of thing is very counter intuitive. Systems that are intuitive require a lot less documentation. On another level, and this is my experience of other leading edge technologies, I think we/you need to consider what it is your users really need. A well done body of documentation will always lag behind any rapidly moving software development activity. Documentation that is out of date is next to useless. So what do you do? Slow down the developers and force them to support or wait for those doing the documentation? Or accept that documentation will never catch up with the leading edge and find another way. I think there is a second way and that is tons of complete working, and documented examples. Such examples should at the same time be examples of the leading edge and best practice. A good clear and relevant example will always get you 70% of where you need to be. Having got that far you can generally figure out the rest using the wiki and other resources.

Any tutorial is of course welcome :) Have you completely mined the examples that come with cocoon? It is slightly out of date, but I found the following very useful:- http://localhost:8080/cocoon/samples/blocks/tour/intro/docs/index.html Regards -- ======= Fergus McMenemie Email:[EMAIL PROTECTED] Techmore Ltd Phone:(UK) 07721 376021 Unix/Mac/Intranets Analyst Programmer === - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Beginner, having bother using a parameter
Another beginner problem. Would somebody please point out where I am going wrong with the following:- The parameter xpathexp is not being seen by my generator.

Re: Caching output from xpathdirectory generator
Thanks all, The change suggested by Joerg works fine. As a result of the correspondance my current understanding of caching pipelines, is that while caching keys etc accumulate down the pipeline the actual data is only cached at the end of the pipeline or after the last cache-able component. However, while Joer's rewrite works, I would prefer to keep everything together within the one matcher statement if possible. Is anybody able to point me to any examples, explanations or docs on the use of "caching-point"s in cocoon 2.1.10? Also, while not essential for the moment, I would like to understand how I could arrange for these and other caches to held or checkpointed to disk. Is all this a read and understand the code exercise? >On 10.04.2007 17:49, Grzegorz Kossakowski wrote: > >> Even though, all components from your pipeline are cacheable you are >> right.

Caching output from xpathdirectory generator
Hi all, Beginner question! I have a directory containing some 1000 xml documents, each of which describes a car. I use the xpathdirectory generator to extract some elements about each car. The directory is then displayed to the user in a series of columns with one row per car or file. I have column headers which allow the output to be reordered as per the content of a particular column. I suspect that the directory is being reparsed for each different sortby value. It takes ages. I would like to be able to cache the output from the directory parsing irrespective of different values of sortby. How do I do it? Also I intend to do a lot of this type of thing. How do I arrange for my caches to be saved to disk?

installing cocoon docs
Please forgive this beginners question:- The cocoon download page contains tar-balls for the source distribution and for the docs. When expanded the docs tar ball contains:- [bigmac24:~/packages/cocoon-docs] fergus% ls -alF total 208 drwxr-xr-x7 fergus fergus 238 Dec 22 00:29 ./ drwxr-xr-x8 fergus fergus 272 Feb 15 15:34 ../ drwxr-xr-x 64 fergus fergus2176 Dec 22 00:28 2.1/ -rw-r--r--1 fergus fergus 31 Dec 22 00:29 broken-links.xml drwxr-xr-x 13 fergus fergus 442 Dec 22 00:28 images/ -rw-r--r--1 fergus fergus 101173 Dec 22 00:03 linkmap.html drwxr-xr-x 25 fergus fergus 850 Dec 22 00:28 skin/ I need a clue what to do with this. I assume that it is to be plugged into the core cocoon application somehow but having spent ages going through the install docs I have found nothing that explains what I need to do. Thanks In advance...
