Monticello: How to select/unselect changes to be committed?
by Nick Chen May 9, 2011

May 9, 2011

Hi When I code, I usually make changes to multiple classes/methods/etc at a time. However, when I commit to Monticello, I would like to organize those changes by breaking them into logical chunks with meaningful commit messages. Consider the following (trivial) example. Imagine that I would like to commit the change to buildMenuDockOn: in one commit and the change to buildStatusBarWith:on: in another commit. What is the easiest way to achieve this? http://forum.world.st/file/n3507981/Monticello.png Other version control systems allow you to selectively stage your changes before committing so I suspect that this should be doable with Monticello. Thanks! -- Nick -- View this message in context: http://forum.world.st/Monticello-How-to-select-unselect-changes-to-be-commi… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

WebClient for 1.2.2?
by Andy Burnett May 7, 2011

May 7, 2011

Hello list, Is there a working version of the WebClient for 1.2.1? I tried loading the webclient-pharo package from squeaksource, but didn't get anywhere. Before, I dug further I wonder if someone can point me in the right direction.

Hello list, I was searching for the right (sustainable) way to extend the browser menu. I searched for the menu labels (show "methods with strings in it" etc.) but couldn't find it, so there must be another hook. Could anyone give me quick pointer? TIA, Markus

Object>>copyTwoLevel
by Panu Suominen May 5, 2011

May 5, 2011

Hi, we have a problem where we must create audit trail of changes made to business objects. Also things should run inside transaction. Our first approach was to create so called command objects from every change but these would be hard to maintain by hand. For example there would be ChangePersonName, ChangeXXXName classes and these would have to be hand created in name: -mehtods. More "clever" approach we come up with is to copy original object and use proxy that records messages send to it and sends them to the copy. Also this proxy creates new proxy when copy returns values. These proxies record message sends to transaction and when transaction is ready these recorded message from all of the proxies are done to the actual objects instead of copies. To create usable copies I found method that (shallow) copies the actual object and its instance variables (Object>>copyTwoLevel). The method is marked to be deprecated soon. Why is that and is there some alternative way of doing this kind of copy? Also if you know some way to trivially handle the audit trail problem I would like to hear... :) -- Panu

No. They were implemented in the Squeak VM that NewSpeak uses. So the code is out there. Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

[ANN] PHANtom: A modern Aspect Language for Pharo
by Lemuus May 4, 2011

May 4, 2011

Hello all, We are happy to announce the release of PHANtom: a modern aspect language for Pharo. PHANtom was built taking into account recent advances in aspect language features such as dynamic advice rescheduling, reentrancy management, and scoping strategies for deployment. The advanced features are not all implemented yet, but the 'normal' features work and are well-tested (about 130 unit tests) so we are relasing it to the world for you to try out. We hope PHANtom can help you to solve some cross-cutting code problems. An overview of the language can be found at http://pleiad.cl/PHANtom Please try it out, see if it works for you, all your comments are welcome! More details: I am doing this as my engineering thesis, under the guidance of Prof. Johan Fabry. PHANtom works in Pharo 1.2.1 and in 1.3, and also in PharoCore. Right now, PHANtom uses Method Wrappers in its' implementation, just like the AspectS language did. But the plan is once we have all features implemented, that we will start compiling using the Opal compiler of Pharo, to make everything go faster. I just put one example from the website here so you can see what it looks like: asp := PhAspect new add: (PhAdvice new pointcut: (PhPointcut new receivers: 'SystemWindow+'; selectors: 'position:'; context: #(#receiver #arguments)); advice: [:context | Transcript show: context receiver. Transcript show: ' moved to: '. Transcript show: context arguments; cr.]; type: #after). asp install. Note: the unit tests of pointcuts take a large amount of time to execute, as some of them match on everything in the image. For more info and how to download PHANtom see http://pleiad.cl/PHANtom
