Hi Richard, It is probably hard to see from 10000 miles away, but we have been quite busy promoting Smalltalk recently. Pharo Days last thursday and friday and the Smalltalk Devroom at Fosdem last sunday take up a significant amount of time. Priorities Stephan

Supply named temporaries to Compiler>>#evaluate:...
by Sean P. DeNigris Feb. 5, 2015

Feb. 5, 2015

I want to be able to evaluate a string like '2 + arg1' and supply anObject for arg1 to the compiler. I naively tried: | aContext | aContext := thisContext copy tempNamed: 'arg1' put: 1; yourself. Compiler evaluate: '2 + arg1' in: aContext to: nil which didn't even come close to working! Any pointers? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Supply-named-temporaries-to-Compiler-evaluate-tp48036… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Custom DND Drop Action?
by Sean P. DeNigris Feb. 4, 2015

Feb. 4, 2015

How do I accept a dropped Morph, but do something other than the default add-as-submorph? I want to drop a Morph into a TextMorph and have it be automatically converted into a TextAnchor, but instead it becomes a submorph and takes over all available space so the contents of the TextMorph can not be changed. Thanks. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Custom-DND-Drop-Action-tp4803667.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Using SmaCC to transform AST?
by Jean-Christophe Bach Feb. 4, 2015

Feb. 4, 2015

Hi, We are trying to transform programs (from Delphi to Java). We already have source and target ASTs and we would like to write the transformation itself. We are wondering if we could use SmaCC to do that but we are not able to figure out how. The documentation is not clear on the fact that it is possible or not to use any AST as input. Does anyone know if it is possible? Then, in the tutorial, the example seems to be a string-based transformation while we would like to transform ASTs. Are we wrong? What have we missed? In Python tests, there are ASTs but we did not find any transformation. Has someone a clear and concise example to help us to start? Thank you in advance, Jean-Christophe

Monticello review web application
by mikefilonov Feb. 4, 2015

Feb. 4, 2015

Hello, I had some spare time and I built a prototype web application for comparing Monticello versions. I developed it using Seaside and Monticello version diff implementation in Pharo. It was super easy to reuse the classes which are responsible for downloading, comparing and generating diffs of Monticello packages. Once again I see how extraordinary it is to have such open system as Pharo. I made this web app for my work with students as often I need to compare their versions of packages across different projects/repositories. For instance, the package is uploaded to PillarHub-Inbox and I want to compare and discuss changes against the main repository. Having this in mind I created a small web app called "Monticello Seaside Review" (didn't get any better). You may find an example review here: http://review.pharocloud.com/msr/review/ehx82xz90kpnm56u9exkrul5q/4 You may also log in to this instance and play with it as it is not really used so no problem if it crash for some reason :) The sources of the project can be found here: http://smalltalkhub.com/#!/~mikefilonov/MonticelloSeasideReview I would be happy of someone finds the project useful and contributes some ideas. Thank you, Mike -- View this message in context: http://forum.world.st/Monticello-review-web-application-tp4803443.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
