[Pharo-project] Morphic replacement
by Fernando Olivero April 27, 2012

April 27, 2012

Dear all, I've been working on a hole replacement of Morphic myself, because if was tired of fixing Morphic (or porting CUIS Morphic into Pharo), and found much more productive the approach of rewriting it from scratch. In my expierience, i was 100% more productive by not trying to be backward compatible with Morphic, Polymorph , etc. I found it easier to come up with a new set of widgets (EntryField, AutoCompletionEntryField, Button, Label, Column, Row, ScrollableColumns) from scratch. They are all fairly tested also. Maybe it's time to move on, and develop from the ground up a Morphic-like successor, instead of fixing the current Morphic. There's no problem with preserving the current UI for all the apps that are out there, and provide a cleaner, simpler UI framework for the new apps. Regarding the new "morphic", I only assume that i have a scalable canvas, and the vm's notifying me of the user events. On top of that i recreated a World, that can have multiple views. There's only one World at a given time. Views are presented within the world in a given viewport, and present a scene. Scene are were the shapes live in. No World as a subclass of PasteUpMorph, no globals such as World, ActiveWorld, Hand. ActiveHand, etcs.. The world has a mouse and a keyboard, which take care of events announced by the world. For example GMouse>>down: aDisplayPosition, would take care of transforming the display position into a world position, into a view position, into a scene position, and finally notifying the proper shape under the mouse that it has been clicked at a certain local position. GShape>>clickedAt: , GShape>>secondaryClickedAt:, etc.. No Events hierarchy, or the awful switch currently in HandMorph ( generateMouseEvent: or generateKeyboardEvent:). I have a "Gaucho" system working now, with GShape (instead of Morphs), using the simple new layouts developed by Juan in CUIS, uniform usage of keybindings across the whole GShape hierarchy, amongst other goodies. It's still tailored to be a Morphic replacement for Gaucho, so first i need to polish a few things prior to releasing it. For example, i'm going to ditch my current scalable canvas implementation, in favor of Athens. Hope that very soon i can provide more details, but my plans are to release it as part of the next Gaucho version, to provide a working example. Fernando

[Pharo-project] PetitSmalltalk: now with a self-contained grammar for number literals
by Frank Shearar April 26, 2012

April 26, 2012

Hi, I branched off PetitSmalltalk-lr.50 and (finally) completed a number grammar. I also completed (*) the GNU Smalltalk grammar + parsing, which is currently in a separate package. So, my question: I have a version merging my changes with PetitSmalltalk-lr.56: shall I submit that (together with the other versions in my branch), or in what other form may I present my work for submission? Thanks, frank (*) I may have missed any special literals - I think GNU Smalltalk has an @@(1 2 3) array literal, for instance.

[Pharo-project] Concrete Type Inference
by Francisco Garau April 26, 2012

April 26, 2012

Hi - we are trying to port to Pharo some work I've done on Concrete Type Inference back in 2001. I've got a Squeak 2.8 image which is working, but having some minor problems with the pluggins. Is there a public repository where old Squeak distributions are stored? Thanks, Francisco

Nice indeed! Are you using a kind of spring layout for the big bang animation?

[Pharo-project] How to disable development tools on Pharo 1.3
by Noury Bouraqadi April 24, 2012

April 24, 2012

I remember having seen some time in the past a menu that allows to shrink the image and disable the world menu. But, I can't retrieve any thing related. I don't care about the menu per se. I'd be happy with a message to send to some object that does the job.

Hi Eliot, at [1] you mentioned a port of MethodWrappers to Squeak 4.2. Is there also a port for Pharo available or do you plan to port it? For those who dont know about MethodWrappers: look at [2] Thanks Torsten [1] http://lists.squeakfoundation.org/pipermail/squeak-dev/2011-September/16156… [2] http://www.refactory.com/Software/MethodWrappers/ -- NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurÃ¼ck-Garantie!

[Pharo-project] type-inference: it works!
by Francisco Garau April 4, 2012

April 4, 2012

Load the attached ChangeSets: first Ti-Engine and then Ti-Support. You could then evaluate the below expressions -- watch the Transcript to see which methods are being analysed. TiSystem current reset. string := '3 + 4'. Compiler new analyze: string in: nil to: nil notifying: nil ifFail: [1]. "=> return {<SmallInteger>} " TiSystem current reset. string := 'Display boundingBox'. Compiler new analyze: string in: nil to: nil notifying: nil ifFail: [1]. "=> return {<Rectangle origin: <Point x: <SmallInteger> y: <SmallInteger>> corner: <Point x: <SmallInteger> y: <SmallInteger>>>}" TiSystem current explore. Analysing 'Display boundingBox' shows a couple of surprises: 1. The code never goes through the #new method (it creates objects using #basicNew and #@) 2. Object code goes through Object>>value but knowing that the implementation just answers self, it could be easily optimised. I will try to package it more nicely under Monticello -- there are still a few rough edges that need to be polished before getting it to the same state it was in 2001... Cheers, Francisco
