[Pharo-project] Standard input in Pharo?
by Andrei Stebakov May 5, 2012

May 5, 2012

I've been just going through "Computer Programming with GNU Smalltalk" book using Pharo 1.0 as an actual ST implementation. The book mentions "stdin nextLine" as a way to get an input from a user via the standard input. Is there a similar class/method in Pharo?

Using the MethodWrapper version that is based on Object-As-Methods, as far as I know. Marcus -- Marcus Denker -- http://marcusdenker.de

[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.

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] Bug in DateAndTime?
by Max Leske March 27, 2012

March 27, 2012

Hi. Evaluating: DateAndTime now asUnixTime and then creating a DateAndTime object from the result: DateAndTime fromUnixTime: <seconds> does not yield an equivalent object. As far as I can tell, this is because the unix epoch is hard coded in two places: DateAndTime class>>unixEpoch "Answer a DateAndTime representing the Unix epoch (1 January 1970, midnight UTC)" ^ self basicNew ticks: #(2440588 0 0) offset: Duration zero; yourself. DateAndTime>>fromUnixTime: anInteger ^ self fromSeconds: anInteger + 2177452800 "unix epoch constant" So in the end I get a difference of 7200 seconds. I'll gladly open up a bug but can someone please confirm that this is actually a bug and that I didn't miss something? Cheers, Max

[Pharo-project] how to get a string read stream from filesystem
by Tudor Girba March 27, 2012

March 27, 2012

Hi, I am using Filesystem, and I would like to get a read stream that provides a string instead of bytes. If I do "aReference readStream", I get a FSReadStream which is a byte stream. To get to the string, I now do the ugly: "aReference readStream contents asString" Is there a cleverer way? Cheers, Doru -- www.tudorgirba.com "What we can governs what we wish."

[Pharo-project] SystemTracer
by Benjamin March 15, 2012

March 15, 2012

Hello guys, for one of my projects, I'm trying to use SystemTracer to create anew image, but it appears that it doesn't work on Pharo ... I can create a new image, but I can't open it. I've tried with an older VM (Squeak 3.8.18beta1U), but it's the same ... Did someone already have this problem ? Does someone have a solution ? Thanks in advance, Ben
