It would be really helpful if you could let me have a list of which bits  
of the SVG you want to use are supported badly by Opera 11, so I can try  
to make sure that they're addressed by the next release, if you wouldn't  
mind. (Onlist or off)

Thanks

[svg-developers] Ruby on Rails and SVG

2011-05-15 Thread cremnosedum
I've been looking into Ruby on Rails for developing websites.  There are lots 
of plug in for it.  I tried searching for SVG plug-ins and couldn't find any.

Has anybody used Ruby on Rails for an application using SVG?  If so how well 
does it work?

Get this to run smoothly and I'll be happy. In Opera Next it does not show and 
hide visibility properly yet.

Re: [svg-developers] Ruby on Rails and SVG

2011-05-15 Thread Mark T
I considered it a while back.
Like when it was 1.nnn.
The recent rewrite/refactor was inevitable, welcome and impressive.
The templates commonly used are not xml considerate.
This is an early impedance. Which complicates quickly.
Your choice will depend on the scope of your project.
Rails is now 'a set of bolts which when used in close proximity can be used
to build Rails applications'.
It is not in of itself a server.
The major attractor AFAIC.tell has been the 'migration' facility.
Which binds simple data-access via forms to SQL schema's.
It does not migrate the data. (Unless code is added to the migration).

Plugins are another attractor.
Until you have to debug them.
A well written class structure is another 'view' of plugin 'architecture'.
Again, the re-factoring to 3.0n is welcome in this respect.

Rails is good for the 46 second client-impress scenario.
Then. into a deployment, good when the scope is narrow.

I hope I have not offended too many Rails phans.
I also hope I have not answered your question.

Thanks for the link, Jan, to this working draft. Of the technologies
listed, I see one oversight that addresses all of the requirements:
 [1],[2].

As demonstrated in the suite of accompanying examples,  enables

a. pseudo 3D

b. artistic effects

c. Compact representation

d. Ease of authoring (the metaphor is based on , already a
part of SVG)

e. Compact syntax

f. Hand authoring

g. Compatibility with SVG gradient syntax

h. Control of the spread of color and transparency values

Additionally,  enables certain classes of non-rectilinear
tilings, perspective transforms, and, in conjunction with filters expresses
certain naturalistic scenes quite conveniently [3]. It also provides
considerable potential for integration with multivariate data streams as
suggested from InkML [4]

I would suggest that it be added to the candidate technologies being
considered. Its utility is slightly more in the "3D direction" and less in
the "gradient direction" than the other technologies in the advanced
gradient requirements draft, but its expressive power is greater than the
others. I can see it complementing the power of some of the others.

For any drawn object (and possibly other items as well, like
gradient-stops), subsets of its attributes and all the attributes of its
modifiers (gradients, filters, patterns, clippaths, masks and animates) may
be modified linearly or curvilinearly as the object is morphed over two-D.
The module for multivariate curvilinear interpolation is patterned upon, but
more powerful than the interpolation module in  and offers obvious
suggestions for desired extensions of the  module (the ability to
change animated values according to any user-defined 2D path). 

I believe the WG had informally decided that , being already
implemented in JavaScript, didn't need native browser support, but the
JavaScript implementation, in the case of more complex effects is very slow
and would benefit from lower-level implementation. The majority of the
user-demanded effects enabled by replicate CANNOT currently be managed
within current SVG without script! 

Given the broad array of important use cases that it addresses, both within
and outside the Advanced Gradients area,  offers a powerful
extension to SVG's arsenal, with many suggestions for syntactic
representation having already been examined and explored in detail. Since
browsers that fully support SVG1.1 will already have the code to support
, and since  borrows extensively from that syntax
(sharing the interpolation module) implementation is likely to be less
costly than it would be for other less powerful methodologies.

It would extend SVG immensely in several directions, allow greater
integration with multivariate data streams, and do so using syntax that is
already familiar to SVG authors.

Respectfully,

David
