Re: [Pharo-users] configurable space in XML Writer tag

[monty]

It's changed to no longer emit that space. I was considering removing it, or at 
least making it configurable, anyway.

That worked, thank you so much! This helps me get running in the interim while 
i investigate how to use Athens.

Re: [Pharo-users] line drawing bug

[joe]

I must have missed the deprecation warnings when i ran my code. 8).

Ill check out Athens, i don’t want to have to rewrite the entire application to 
support a new drawing backend. As a first step it would be great if i could 
render to an Athens canvas using the same API or something like it, but in my 
quick experiments I’ve had no luck. I’m sure I’m doing something wrong.

Is there any Athens tutorial documentation? All I’ve found is forum posts and 
videos and most of that stuff is quite old and there are a lot of broken links.

Re: [Pharo-users] Plans for XSD in XML(Parser) the foreseeable future?

[monty]

Unfortunately not. It's a major effort, and I'm not able to devote the time to 
it now.

Re: [Pharo-users] line drawing bug

[Nicolai Hess]

Hi Joe,

the problem is that the BalloonCanvas (or some objects it is using) aren't
fully reset after some drawing operations.
(the drawString method for example sets the sourceForm as glyph to be
drawn).

it should work if you do not store the canvas instance, but create a new in
every loop:

points do: [ :p |

   canvas := form getCanvas asBalloonCanvas aaLevel:4; yourself.

   canvas drawPolygon: p
  color: Color transparent
  borderWidth: 1
  borderColor: Color red.

   canvas drawString: p first asString
  at: p first
  font: nil
  color: Color green.
].




Or just reset the engine state (but I don't like this solution, the engine
state should be private to the canvas).

points do: [ :p |

   canvas drawPolygon: p
  color: Color transparent
  borderWidth: 1
  borderColor: Color red.

   canvas drawString: p first asString
  at: p first
  font: nil
  color: Color green.
   canvas resetEngine.
].

DRGEO:


20.9% {27116ms} DrGPointMorph>>drawOnAthensCanvas:
|16.7% {21720ms} AthensCairoCanvas(AthensCanvas)>>createPath:

Storing the path in DrGPointMorph, rather than recreating for each draw:,
should save alot of time.


Indeed should work nicely for point with round shape. For rectangle 
shape it is not necessary, this what I did in the demo.

7.7% {9962ms} DrGTextMorph>>drawOnAthensCanvas:
   | 7.7% {9962ms} Form>>asAthensPaintOn:

Same thing here, only storing the paint, rather than converting from form
each draw.
In my demo, the text changes at each iteration. Useful for static 
geometric item label thought. But I already optimized this by discarding 
empty label


The cache suggestions will be find for static surface, it does not apply 
always though.
In the scenario where Dr.Geo is used for animated demonstration, I 
already found a few optimization for Dr.Geo itself without touching to 
the Athens layer.


Thanks for your review

Re: [Pharo-users] installation of packages on 6.1

[Baveco, Hans]

I used:

Metacello new
smalltalkhubUser: 'hernan' project: 'Territorial';
configuration: 'Territorial';
version: #'bleedingEdge';
load

I don't think the problem is related to Territorial; same thing happened when
