Hi Stef,
Your email made me think a lot.
another

This would be so great.
But in roassal you do not have the concept of a
polylines?
Actually no, but it is likely that we should. A general way to defines
polygons is the way to go.
I do not get why you want to pollute Roassal with
SVG names.
If you introduce the notion of Path why don;t you do it independent of
SVG
because SVG is one way to represent path.
After having played with Athens, I understand better what you actually
mean.
Indeed, the end user should work with a notion of polygon in general, and
not with SVG.
Because I think that as a user I do not want to
if my code works on svg
or another external format.
It follows the same pattern no?
Yes but this is different because ROBox is a roassal box not an svg or If tomorrow you get a pdf reader and access a
library of pdf library. Do
you want your reader to
have ROPDFBox?
in SVG you also have
• Rectangle <rect>
• Circle <circle>
• Ellipse <ellipse>
• Line <line>
• Polyline <polyline>
• Polygon <polygon>
• Path <path>
So I imagine (and hope) that you will not introduce ROSVGRectangle
ROSVGLine
ROSVGCircle?
So why introducing ROSVGPath
You are very very right. We indeed do not want to introduce all these
classes.
Your email made me think about something: rewriting Roassal from scratch,
but putting the core notions brought by Athens at the center of Roassal. I
spend some time on getting the camera working in Roassal, but Athens was
not ready yet. More Roassal will use Athens, and more we are taking
advantages of the graphic card.
Also, do we have to wait for the text editor to
include Athens in Pharo?
The text editor is essentially to bootstrap and remove Morphic right? But
until then, Athens could be part of Pharo. I am now using the Moose image,
which is nicely packaged with proper fonts and Athens. Since there are many
users of Roassal on Morphic, it is hard for me to move to 100% Athens.
What do you mean? Athens is in Pharo 3.0 by default. We are no longer
loading it manually. You can safely invest all your energy in Athens :).

Thanks again for your email
Alexandre
