Re: [Pharo-users] OSSubProcess and image startup

by Mariano Martinez Peck

Hi Norbert, I have never seen that issue before. Do you know if it happens only with that image (maybe a condition that happened at image save)? Or can you reproduce it with a fresh image?

How to get GLMSystemWindow from GTPlayground

by Norbert Hartl

I wanted to write a small utility snippet involving GTPlayground. I want to transfer all my playgrounds from one image to another image. Something like (GTPlayground allInstances reject: [ :each | each title = 'Playground' ]) do: [ :each | (each title asFileReference , #pg) writeStream nextPutAll: each entity content string; close ] The snippet depends on the window title. I think I've found a bug because in the menu "Change titleâ¦" does not change the title of GTPlayground but of the GLMSystemWindow it is associated with. I did not find the way to get the GLMSystemWindow from the GTPlayground in order to be able to access the title. thanks, Norbert

CFP - IWST 2016 - International Workshop on Smalltalk Technologies

by jannik laval

[Please accept our apologies if you receive multiple copies of this call] [Please send to interested colleagues / mailing-lists] ************************************************************************************************************ CALL FOR PAPERS IWST16 â International Workshop on Smalltalk Technologies Prague, Czech Republic; August 23th, 2016 ************************************************************************************************************ ------------------- Goals and scopes ------------------- The goals of the workshop is to create a forum around advances or experience in Smalltalk and to trigger discussions and exchanges of ideas. The topics of your paper can be on all aspect of Smalltalk, theoretical as well as practical. Participants are invited to submit research articles or industrial papers. This year we want to open two different tracks: one research track and one industrial track with less scientific constraints. We expect papers of three kinds: Short position papers describing emerging ideas Long research papers with deeper description of experiments and of research results. Industrial papers with presentation of real and innovative Smalltalk applications; this kind of paper should enlighten why Smalltalk is really appropriate for your application. We will not enforce any length restriction. -------------------- Important Dates -------------------- Submission deadline: *May 15th, 2016* Notification deadline: June 20th, 2016 Workshop : August 23th, 2016 *All accepted papers will be published in ACM DL (To be confirmed)* *Best papers would be extended in an International Journal* ------------------- Topics ------------------- We welcome contributions on all aspects, theoretical as well as practical, of Smalltalk related topics such as: -Aspect-oriented programming, -Design patterns, -Experience reports, -Frameworks, -Implementation, new dialects or languages implemented in Smalltalk, -Interaction with other languages, -Meta-programming and Meta-modeling, -Tools ------------------- Best Paper Award ------------------- To encourage the submission of high-quality papers, the IWST organizing committee is very proud to announce a Best Paper Award for this edition of IWST. We thank the Lam Research Corporation for its financial contribution which makes it possible for prizes for the three best papers: 1000 USD for first place, 600 USD for second place and 400 USD for third place. The ranking will be decided by the program committee during the review process. The awards will be given during the ESUG conference social event. The Best Paper Award will take place only with a minimum of six submissions. Notice also that to be illegible, a paper must be presented at the workshop by one of the author and that the presenting author must be registered at the ESUG conference. ------------------- Publication ------------------- Both submissions and final papers must be prepared using the ACM SIGPLAN 10 point format. Templates for Word and LaTeX are available at http://www.acm.org/sigs/sigplan/authorInformation.htm. This site also contains links to useful informations on how to write effective submissions. ------------------- Submission ------------------- All submissions must be sent via easychair: https://easychair.org/conferences/?conf=iwst20160 ------------------- Program chairs ------------------- Anne Etien (UniversitÃ© de Lille 1, France) Jannik Laval (UniversitÃ© Lyon 2 LumiÃ¨re, France) -- ~~Jannik Laval~~ Enseignant-chercheur Responsable PÃ©dagogique Licence Coordonnateur de Projet en SystÃ¨me d'Information IUT LumiÃ¨re, UniversitÃ© Lyon LumiÃ¨re laboratoire DISP http://www.jannik-laval.eu http://www.phratch.com http://www.approchealpes.info

OSSubProcess and image startup

by Norbert Hartl

I have OSSubProcess installed because I use gitfiletree in pharo5. Everytime I start my image now I get the following dialog. Anybody knows this? Is this a bug and should be reported? thanks, Norbert

"Pharo forked in 2008, that is a long time ago. Get over it. We are not looking backwards, we are looking forwards." Yeah who cares ? Afterall Squeak only made Pharo possible. No big deal, lets look forward. Pharo is not Smalltalk and is not Squeak, its back from the future.

Nice. May be there is a typo on the phrase "mathematician from the XIIIe century" (the "e" at the end of XIII looks strange).
