Hi Johan, It is not only reasoning about Java. A connection to Java is very useful to communicate with Java libraries (for example, graph libraries). Also, what Johan Brichau did in VW was to directly query Eclipse for reasoning about Java. Pretty cool :) Cheers, Doru On 8 Jun 2010, at 23:27, Johan Fabry wrote: > > The problem with the Moose and reasoning about Java thing (I think > this is what you are thinking about) is to keep the importer > maintained, as Doru convinced me.

The problem with the Moose and reasoning about Java thing (I think this is what you are thinking about) is to keep the importer maintained, as Doru convinced me. In the end the infusion way works OK for me, so right now I am not looking for another solution.

Alien for Squeak 4.1/Pharo 1.1?

by Joachim Geidel

I somehow managed to load Alien into both Squeak 4.1 and Pharo 1.1. You can see what I had to do in the installation instructions for JNIPort on SqueakSource. It's not for the faint of heart... ;-) In Squeak, this meant removing the Alien-Prereqs package and all Parser/Scanner/MethodNode changes, as they are redundant or obsolete in Squeak 4.1. I have a version of the Alien-Core Monticello package which loads cleanly in Squeak 4.1, if anybody is interested. However, this package does not load in Pharo 1.1 beta 11367 - some of the changes I removed still seem to be needed there. What are the plans for Alien? When will it be made available for Squeak 4.1 and Pharo 1.1? I am interested in this because I need Alien as the base for JNIPort, and I would like to at least run the JNIPort test suite on a stable version of Alien before officially releasing JNIPort 2.0.

JNIPort preview for Pharo available on SqueakSource

by Joachim Geidel

I have made a preview release of JNIPort for Pharo/Squeak available on SqueakSource: http://www.squeaksource.com/JNIPort.html JNIPort is a Smalltalk library which allows Java code to be invoked from Smalltalk. It acts as a bridge between the world of Smalltalk objects and a Java Virtual Machine (JVM) where Java code is executing. If you want to know what can be done with JNIPort, see http://philemonworks.wordpress.com/2010/04/29/google-api-access-from-smallta lk-using-jniport/ for an example. Installation instructions are on the Wiki at SqueakSource. See http://jniport.wikispaces.com/ for more information about JNIPort. The current state of the Pharo/Squeak version of JNIPort (as of 7 June 2010): * Callbacks from Java to Smalltalk are not yet supported. * In contrast to VisualWorks and Dolphin, JNIPort does not create ghost classes as wrappers for Java classes, but creates Â³realÂ² classes which can be seen in the system browser. It also does not copy prototypes of CompiledMethods when a wrapper class or a Java class is created, because this causes VM failures in Pharo 1.0. Instead, methods are compiled from source code. This has a performance impact, of course. * Another difference from the VisualWorks and Dolphin versions is that wrappers for Java methods without arguments donÂ¹t have selectors ending with an awkward Â³_nullÂ² suffix. * JNIPort has been developed and tested with Pharo 1.0 on Mac OS X 10.6.3. If it works in Squeak and on other operating systems has yet to be tested. * I have briefly tested JNIPort with Pharo 1.1 beta 11367, but this needed some manual modifications of Alien Â without them Alien causes problems in Pharo 1.1. * In Pharo 1.1, starting a JVM needs 11 seconds vs. 4 seconds in Pharo 1.0. I donÂ¹t know yet why. * I donÂ¹t have a Metacello configuration yet. The next steps will be: * Adding support for callbacks from Java to Smalltalk. * Testing it on more platforms. * Reorganization of the documentation on the JNIPort wiki, and addition of Pharo/Squeak specific documentation similar to the documentation for the VisualWorks version. * Release of JNIPort 2.0 for VisualWorks and Pharo/Squeak when everything is stable. This will be after the release of Pharo 1.1. If it works in Squeak 4.1 or on Linux or Windows, please let me know, especially if you had to do something which might be worth mentioning in the installation instructions. Have fun with JNIPort, and let me know if it works! Joachim Geidel

[JOB] We are Looking for a Pharo Engineer

by Marcus Denker

Hello, INRIA RMOD is looking for a full-time engineer for helping with Pharo development. As researchers, we need a really great system to explore new ideas with. The job of the engineer is to help us by improving the infrastructure we use for our work. What this of course means is that it's kind of a cool job: work in a research lab, but no paper writing, no teaching, no administration. In addition: - live in France (one hour from Paris, 1h20 from London, 35 min from Brussels) - try a lot of good beers (our office is just 10km from the border to Belgium) - french food - code all the day in Smalltalk and a bit of C Apparently from what the DHR services told us, the salary will depend on years of expertise and diplomas. We can think that 2700 Euros (before final taxes) should be a good working number for a candidate of the experience we are looking for. In France the employer pays already social security and pension. So the salary already includes lots (and lots) of deductions compared to e.g. a german brutto salary. Lille is an active city but not expensive (lot of students...), centrally located with good connections by train to everywhere (including CDG and Brussels airports). The job will to continue making Pharo better - better tools - better network support - better compiler infrastructure - improve the VM - help with day-to-day bug fixing and constant improvement Therefore we are looking for a candidate with some years of Smalltalk (possible Pharo/Squeak) background. Duration: 30 months Starting date: October 2010 Location: Lille (no remote job possible) Official Job Description and Application via: http://bit.ly/dyhdba Deadline: 15 July 2010 More about INRIA Lille: http://www.inria.fr/lille/ INRIA in General: http://www.inria.fr Engineers at INRIA: http://www.inria.fr/travailler/metiers/accompagnement/dev_applications.en.h… Lille: http://en.wikipedia.org/wiki/Lille http://www.mairie-lille.fr/en http://wikitravel.org/en/Lille Do not hesitate to contact us for more information.
