[Pharo-project] Migrating from VSE
by S Krish Feb. 24, 2012

Feb. 24, 2012

Can anyone can throw in the challenges in migrating VSE into Pharo.. UI -> Morphic a big change.. rest of the code -> Pharo base.. do we have grease / or anything akin.. to ease migration Or is it simply the same effort as pushng this into VW where it would stand better guarantees..? both from a corporate plan/ support etc.

[Pharo-project] fun with NBOpenGL

This trick is not fully compatible with morphic, since it ignoring clipping bounds etc. If you want to have full integration with morphic, first turn on "useOwnForm" flag first then viewport will copy rendered pixels into own buffer, which is then can be used for subsequent drawing on morphic canvas. See GLViewportMorph>>drawOn: aCanvas Probably we should add a bounds checking in NBGLDisplay>>updateForm: aForm bounds: aBounds because if you go outside of form's bounds, you have imminent crash due to memory corruption. What can be done, code can be rewritten to take into account a canvas clipping + origin, to get more correct (and safe) copying of rendered pixels, but still avoiding extra copy to intermediate form. Anyways, i don't like the fact that it copying the rendered stuff from video memory back to main memory, and then copying stuff back to video memory (but this time by morphic + VM). But this was a cheap way to get demo working and morphic integration. If i would be making app which using opengl for rendering, i would never copy things like that, because it just a waste of cycles causing a big impact to frame rate. What works for demo, is not really applicable in serious application. Â :) In serious app, i'd rather copy morphic Display form into separate texture and then render it along with other Â stuff, which is already in video memory. But this approach needs more time investments, which currently i don't have, and actually heavily depends on what you want from your app. Anyways, if there's someone who having spare time to fix NBGLDisplay>>updateForm:bounds: implementation to make it safer, i would appreciate that. -- Best regards, Igor Stasenko.

Re: [Pharo-project] New IDE alternative (was Misc. newbie questions)

I would like to contribute to this discussions, since is related to my work. I've really enjoyed the discussion on this thread on enhancements or full replacements to the traditional tools for programming that we have since smalltalk-72-76. In the context of my thesis , i'm researching the use of development environments which are built using the "object-focused metaphor" as opposed to traditional ones that use the "view-focused" metaphor. SELF was the first (and 20 years later still impressive) , and Code bubbles is the latest. We are building a system called Gaucho, which allows to manipulate all the elements that make up the program, by direct-manipulation of visual entities called shapes. The goal is to minimize the presence of the tools by giving prominence to the objects themselves. Gaucho allows developers to freely place the shapes within an infinite plane, called the pampas, which eases the task of comparing different objects, and enables developers to make use of spatial arrangements to support task context. Gaucho also remembers all the changes made to the system, both visual and system changes, for better understanding past and the current development session. I believe these features greatly improve the programming experience, as opposed to more tool based approaches. In the attached a simple example of a Gaucho, running on top of Pharo, rendering with Athens with a Cairo and Pango backend, without morphic! For having this i had to implement: * simpler and more manageable ui framework than morphic, rethought completely from scratch for a vectorial canvas. *.a non-overlapping scheme,so the shapes can push each other away *.complete change model etc... I've been working actively to release a new version, and soon will have it ready.
