[c3] Image reader, does c3 have one?
Hi all,
I am looking for an
http://cocoon.apache.org/2.1/userdocs/core/image-reader.html in c3, but
have not found anything. Did I not look hard enough, or simply there is
no image reader yet?
If there is no image reader is there a note about best practice to
migrate a 2.1 component to 3.0?
TIA for any information.

Good to see someone working with C3 and that it is getting some
attention. I hope to convince some people here that we should look at
it, but that will take a long time.... :-(
In any case, it seems you already have your first concrete (albeit
simple) example. Just document what was required to move the image
reader over as the first example in the "How to migrate Cocoon 2.2
components to Cocoon 3.0" section of the documentation and web site
(yeah, I know, there needs to be a place to put the examples first,
but that is left as an exercise for the reader)...

ATM I am developing a prototype for a customer based on c3 and will come
to the point where I need to develop something in that direction. I will
commit afterwards if nobody beats me to it. ;)

Not really yet but I guess I will run into that challenge soonish, if
somebody can share her experience in that field I would more then
welcome that.

You are definitely right: in the cocoon-sample module of cocoon3 sources
there is already some JS, but the rest is still missing.
In order to speed up the implementation of your idea, If you already
have some snippets or working samples about this, we would be glad to
include them in C3 sources.

Nice idea: such checklist can start from some concrete examples and grow
up to a more general approach in migrating from 2.X to 3. Again: do you
have some of such concrete examples? ;-)

Exactly.

You're welcome :-)

Yeah, sweet that did the trick. :) I ended up to use {map:1} since it
closer to old school grammar. ;)
BTW we should add an example to implement the presentation layer stack
(css, js, images, ...) to give the people some c&p snippets.

I guess we should put together a small checklist since people have 2.X
components they want to migrate if switching to c3. For 2.2 ones which
are based on spring there is not much to change, but old avalon
components needs more work. c3 does not support avalon based components
any more, right?
Thank you very much Francesco (especially for your impressive QUICK
reply)!

Hi Thorsten,
upon reading your e-mail I've realized that in the cocoon3 samples there
was nothing about image reading, while the C3 reader is perfectly
capable of handling such requests, so I've just added and committed.
Basically, what you need is only changing what used to be (in C2.1)
<map:match pattern="images/*.gif">
<map:read src="read/{1}.gif" />
</map:match>
into
<map:match pattern="images/{filename}.gif">
<map:read src="read/{map:filename}.gif" />
</map:match>
> If there is no image reader is there a note about best practice to

Unfortunately there is no documentation about this, but any comment and
/ or request is very welcome from you :-)
