[Pharo-users] Gitfiletree error when loading Mapless
I'm attempting to load Sebastian's latest contribution [1] and when doing so I'm getting an error related with git: Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. Looking into the code, I found it is executing this to clone the repo: git clone g...@github.com:sebastianconcept/Mapless.git Which if I run in the command prompt I get the same output. As far as I can understand it is trying to access github with the user git. If I clone the project as: git clone https://github.com:sebastianconcept/Mapless.git It works okay. Any suggestion?

Re: [Pharo-users] Athens question: AffineTransform, AthensCairoMatrix and Float values
On 11 April 2014 20:24, Juraj Kubelka juraj.kube...@gmail.com wrote: Thank you Igor, I understand and I agree. Just can you clarify one think. Maybe I use it wrong. Right now in Roassal2/Trachel a shape has instance variable called matrix which is an AthensAffineTransform object. And if someone calls translateBy:, or scaleBy:, etc. I call the appropriate method on AthensAffineTransform. Do you say, that I should rather have instance variables position, rotation, and scale? Do I understand well? I thought it is better (faster) to keep the matrix and in #drawOn: only call #multiplyBy:. it doesn't really matters.. and up to your convenience. sometimes it's convenient to use decomposed form (e.g. translation, scale, rotation) instead of full matrix, sometimes not.. depends how/who/where you using it. And another question. Right now a rectangle is drawn like this: -=-=-=-=- computePath canvas ifNil: [ ^ self ]. path := self athensCanvas createPath: [ :builder | builder absolute; moveTo: rectangle topLeft; lineTo: rectangle topRight; lineTo: rectangle bottomRight; lineTo: rectangle bottomLeft; lineTo: rectangle topLeft. ] -=-=-=-=- I do not see a method which draws rectangle directly. This examplehttp://zetcode.com/gfx/cairo/shapesfills/ shows there is a direct support for rectangle drawing. Am I right we do not have that support in Athens? Is there a reason for it? Because there's only one method which draws any kind of shapes (including rectangle). All you need to do is to draw it: canvas drawShape: (0@0 corner: 100@100). or canvas setShape: (0@0 corner: 100@100). ... canvas draw. else there would be need to add dozens of drawRect: drawOval: drawZigZag: drawAnotherWeirdThing: instead of simple method which covers all.

I suppose I do not have to keep float values in AthensAffineTransform object. My suggestion is to ensure float values where it is expected. For example the method #loadAffineTransform could be like this: -=-=-=- AthensCairoMatrixloadAffineTransform: m self initx: m x *asFloat* y: m y *asFloat* sx: m sx *asFloat* sy: m sy *asFloat* shx: m shx *asFloat* shy: m shy *asFloat* -=-=-=- Which will mean 6 extra #asFloat message sends, even if they're already floats or ints but not Fractions (and in 99% of cases they are, so you will slow down everything for the sake of 1%). I prefer that user supplies already prepared data, so it don't have to be implicitly converted since it takes extra CPU cycles, which can be spent somewhere else. But yes, it needs to be ensured, but at different place: where you building that AthensAffineTransform AthensAffineTransformsx: number sx := number = AthensAffineTransformsx: number sx := number asFloat .. (and for the rest of accessors) like that it will ensure that AthensAffineTransform always stores floats, which i'm not really like because integers is perfectly fine too.. its all about Fractions. Right now I have to do that transformation myself whenever I use Athens objects. I see it error prone and I do not see it obvious. On other hand I do not want to keep float values in my AthensAffineTransform, because if user do #scaleBy: 0.7 and then #scaleBy: (1/0.7) I want to get the same original value. Otherwise the image could change its size. On your place i'd better forget about it. That's impossible when you dealing with floating point values.. and multiple matrix operations. Unless you explicitly control it by yourself, but that certainly should be outside of AthensAffineTransform/Athens. The same change could be for other methods in AthensCairoMatrix. Again, that would mean dozens of extra message sends at every single place, whether it needed or not.. Like: AthensCairoMatrixtranslateX: px Y: py needs to be replaced with: ^ self primTranslateX: px asFloat Y: py asFloat instead of direct call, plus adding #primTranslateX:Y: method, of course. Do you really want to pay a price of 50% less performance (or more) in exchange of i don't wanna think what i passing to it? Because apparently, you always need to think what you passing - one cannot just pass a random object to some method and expect it to work, isn't? Because i don't. All you need is to avoid using Fractions.. because integers or floats is perfectly fine. Fraction created only if you use division on integer..

And that's why you got the horizontal line btw.. because of using private protocol bypassing coordinate tracking. Why I have to use “moveTo:”? In C-example they do not use it. But I have to, otherwise there is an extra line on the canvas: Well, I see in AthensCairoPathBuildercreatePath:, there is call of self moveToX: 0 Y: 0.”. If I remove it, I do not have to write “moveTo: 0.5@0”. So, I understand why I have to write it in my code. The question is what is the purpose of self moveToX: 0 Y: 0.”? I guess it simplify some situations, am I right? Which one? the initial moveTo: command lets you set the origin (starting point) of your path. if you don't start path with moveTo: command, it is implicitly set to 0@0.
