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: April 10th, 2015* Notification deadline: May 20th, 2015 Workshop : July 15th, 2015 All accepted papers will be published in ACM DL ------------------- 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 eligible, 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.

Hello Martin, if you're using the ubuntu ppa, the sources file is *NOT* required by the launcher (it works without it). You can install the source by executing "apt-get install pharo-sources-files" Kind regards, Markus On 04.03.2015 09:26, Martin BÃ¤hr wrote: > Excerpts from Marcus Denker's message of 2015-03-04 09:13:45 +0100: >>> Date fromString: method >>> contains a method comment on Windows and on Ubuntu it doesn't even include an implementation. >> Wowâ¦ that means that the sources file is corrupt. > actually, i thought the source file was simply missing. > pharo kept telling me every time i start that it can't find the V3 sources, until > i downloaded them manually and put them in the right place. > > greetings, martin. >

Re: [Pharo-users] scaled decimal number for currency

by Esteban A. Maringolo

Can you please share with us how are you defining the mapping for such field? For what I was able to see in the current implementation the Pharo dialect doesn't provide support for ScaledDecimals. PharoDialect doesn't provide a #fixedPointType, so the number is coerced to a float. Adding support for it shouldn't be much hassle. Let me see if I can spare a couple of hours to look into this. See comment of #convertToNumber:for: "Convert to an arbitrary numeric type. Make sure our precision matches. *Hate* floating point" :) Esteban A. Maringolo 2015-03-05 11:16 GMT-03:00 Pablo R.

Re: [Pharo-users] scaled decimal number for currency

by Pablo R. Digonzelli

I'll try. Supose i have an item wich has an id and a price . For example id is 77 and price 41.69. If I use ScaledDecimal with scale 2 for price , glorp create this string for query execution: 'INSERT INTO item (id,price) VALUES (77,41.69s2); and of course give me a GlorpDatabaseWriteError for the 's2' part of the string. If i comment the line "aStream nextPut: $s; print: scale." in printOn: of ScaledDecimal glorp works with no problem. I hope you understand. Sorry for my bad english TIA Ing.

Re: [Pharo-users] Roassal scroll bar builder

by Pierre CHANSON

Hi Ofrray, yes it is due to view inspect inspect. Actually I already wrote a "b view inspect", so you just have to execute the code, but if you inspect it, you get inspector on inspector. There is always this behavior, due to a <anRTView> signalUpdate, embedded with the events, that will affect the view on your last inspector. In the others, (if you do inspect inspec inspect...) the events will occur but you don't see them in real time. If you refresh the view you will see that these events happened.

Re: [Pharo-users] Linux and Windows 3.0 differences

by S Krish

"copy&paste from Chrome to Pharo 4.0 workspace/Playground on Ubuntu did not work either." As also an issue if you do it from MS Office, MS Outlook .. et als. I have mostly seen this to be a quote error. That is the quote surrounding any string is copied with an encoding that makes it some other character that is not then executable in Pharo. So while you copy paste, a) The Chrome content should be inside <pre> </pre> tags to preserve the encoding. OR b) physically replace the characters with a quote in keyboard. I do not think it is anything to do with Pharo to fix. On Wed, Mar 4, 2015 at 1:15 PM, Sebastian Heidbrink <sheidev(a)yahoo.de> wrote: > Hi! >
