[Pharo-project] PipeableOSProcess under windows
by Camillo Bruni May 6, 2013

May 6, 2013

Am I correct in the assumption that OSProcess does not properly use the Path env variable? I have MinGW installed and the Path variable is set up correctly, so I do bash --help in the CMD window, however something like `OSProcess waitForCommand: 'bash --help'` does not work. Is there a workaround for this issue?

[Pharo-project] Programming interactions with State Machines
by Carla F. Griggio May 6, 2013

May 6, 2013

Hello everyone! I'm here to tell you that I started experimenting with a Pharo implementation of this idea: http://swingstates.sourceforge.net/. For those into UI programming I really recommend reading the first paper cited in that page. It's for programming user interface interactions with state machines, an approach to avoid the classical "callback spaghetti" that sometimes we get with event handlers everywhere. I have a tiny first step that shows an example for changing the color of a button on mouse over and changing it back to the original color on mouse out. You can download the code from: http://smalltalkhub.com/mc/CarlaGriggio/StateMachines/main Evaluate this for executing the example: SMButton openWithStateMachineInteraction And here is the code of the state machine for that example: SMButton class >> openWithStateMachineInteraction |button stateMachine iddle hover | button := self new. stateMachine := *SMStateMachine* newForWidget: button. iddle := (*SMState* newWithName:'iddle') enter:[:stMachine | stMachine widget color: Color yellow ]; addTransition: ((*SMTransition* forEvent: 'mouse enter' withOutputState: 'hover') transitionAction: [:stMachine | stMachine widget color: Color red ]). hover := (*SMState* newWithName:'hover') addTransition: (*SMTransition* forEvent: 'mouse out' withOutputState: 'iddle'); addTransition: (*SMTransition* forEvent: 'mouse enter' withOutputState: 'hover'). stateMachine addState: iddle; addState: hover. stateMachine attachTo: button. ^button openInWorld That code corresponds to the following states diagram: [image: Inline image 2] I will keep experimenting with this during the next weeks, and specially try to compare the pros and cons with regular event handling. Something cool about this approach is that the same widget could change its interactive behaviour on the fly by just attaching a different interaction state machine to it :) Also, I'm doing this for programming user interface interactions, but it could be useful for anything that can be modelled with a state pattern. Is there something similar out there already working? I was so eager to try this that I didn't look for related existing projects. Cheers! Carla.

[Pharo-project] RFB in 2.0
by Norbert Hartl May 6, 2013

Esteban, now I can tell that it isn't working for me either. Socket is open and server is running. But there are immediate disconnects when trying to connect to a pharo2.0 image. Did you figure it out? Norbert

[Pharo-project] about logCr: vs. log: vs. trace:/traceCr:
by StÃ©phane Ducasse May 6, 2013

May 6, 2013

Hi guys Stupidly I introduced log: a while ago to replace Transcript show:. Now is the current situation. I still want to remove all the use of Transcript show: Now since I thought I did a mistake with log: because it overload Integer>>log: I introduced trace: and traceCr: Now I do not like traceCr: because it is not a cool message. So what do we do: 1) we use crLog:, logCr: and deprecated log: 2) we use crTrace:, trace: and traceCr: I really prefer solution 1 but I would like to hear from you. Stef
