troubles with JNIPort on Pharo 5 / Java 8
by Tudor Girba Aug. 10, 2015

Aug. 10, 2015

Hi, I am having trouble running JNIPort with Pharo 5 and Java 8 on Mac OS X 10.10.4. The code loads fine: Gofer new smalltalkhubUser: 'JNIPort' project: 'JNIPort'; configuration; loadVersion: '3.0-alpha'. However, I do not know where to point "JNIPortJNIInterface libraryFile:" to. In the original instructions for Java 1.6, the code looked like: JNIPortJNIInterface libraryFile: '/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Libraries/libclient.dylib' With JDK 1.8 (and even 1.7), the file organization seems to be different and the libclient.dylib does not exist. I tried to point it to libjli.dylib, which looks similar, but that does not seem to work: JNIPortJNIInterface libraryFile: '/Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/MacOS/libjli.dylib'. Can anyone point me in the right direction? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Hi Noury, Thanks for the link to the documentation. I have managed to get up and running now - very cool! One question. When I execute 1+1 on the Pharo (pink) playground, I see the code appearing in the web browser log, but it doesn't appear to execute. Is it supposed to, or at this stage is it just showing that it made it over to the web browser? Cheers Andy

Create maps from an SVG file in Roassal
by FranÃ§ois Stephany Aug. 4, 2015

Aug. 4, 2015

Hi there, I'm trying to import an SVG file describing the provinces of Belgium in Roassal. I've cleaned an SVG file found on wikipedia and trying to import it. I'm trying to imitate the way it is done with Countries. So: RTMapBuilder class>>provincesOfBelgium > ^ #(#antwerp #brussels #eastFlanders #flemishBrabant #hainaut #liege > #limburg #luxembourg #namur #walloonBrabant #westFlanders) > and implemented to corresponding SVG paths. Here's one example: RTSVGPath class>> antwerp > ^'m 177.419,25.0693 1.379,-3.5593 -2.986,-1.3778 -3.33,0.5742 > -0.114,-3.1001 -4.019,-4.0187 1.492,-5.9704 -2.181,-2.8706 -1.952,-0.2298 > -1.034,-1.2628 -2.411,5.1667 -3.673,3.7892 -3.101,-2.067 -5.396,1.378 > -2.068,-1.8371 4.479,-0.9188 0.345,-5.1667 -6.2,-2.1815 -4.938,5.741 > 0.114,2.8704 -8.611,-0.574 1.264,-5.5112 -5.397,0 -6.43,3.4444 1.263,4.5929 > 2.411,2.7555 -1.492,2.6409 -4.478,-0.6891 0.115,-2.7555 -6.43,0.3443 > 0,2.4112 2.296,0.5743 -0.345,5.5112 3.904,1.0336 -3.1,3.3295 3.056,7.4863 > 0.504,5.9475 -7.923,0.2296 -2.985,3.1002 1.722,1.837 -0.114,3.5595 > 2.889,0.4893 3.352,-0.9423 7.038,4.5375 3.704,-0.5553 1.759,1.7593 > 3.149,-1.7593 4.075,2.1297 2.963,-3.6118 11.112,-1.7592 0.092,3.3337 > 11.576,-3.6113 1.204,-3.0562 5.001,-0.8332 2.129,-3.8894 4.723,-0.7409 > 0.741,-1.9448 2.223,0.8336 1.481,-0.8336 0.186,-4.9079 -4.075,-2.0373 > 1.605,-5.4063 z'. Very naively, I've tried: provinceExample > "self new provinceExample" > | b | > b := RTMapBuilder new. > b countries: RTMapBuilder provincesOfBelgium. > b color: Color lightGrey. > b open. Which does not display anything. I suspect the problem lies in the coordinates of my paths. Is there a README somehwere or the original file that was used to generate the world map of the examples? Cheers, Francois

protobufs for Pharo
by Benjamin Pollack Aug. 3, 2015

Aug. 3, 2015

Hey all, Has anyone implemented protobufs for Pharo yet? Iâve not managed to find any examples, so I assume the answer is ânoâ, but I thought Iâd check here before rolling up my sleeves and writing one myself. (My specific target here is to write a RethinkDB driver, so if someone has magically also done *that*, please let me know, too.) Thanks, --Benjamin

Pillar automatic anchors
by Peter UhnÃ¡k Aug. 3, 2015

Aug. 3, 2015

Hi, I would like to resolve this issue: Automatic section anchors: Each section title should automatically generate an implicit hyperlink target (aka, anchor) pointing to the section. The text of the hyperlink target (the "reference name") is the same as that of the section title. however since I'm not familiar with Pillar I don't know how acceptable this solution could be ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ PRHTMLWriter>>visitHeader: aHeader | level | level := self configuration headingLevelOffset + aHeader level. "h1 to h7 exist." level := level min: 7 max: 1. canvas tag name: 'h' , level asString; parameterAt: 'id' put: (self createIdForHeader: aHeader); "<<< addition" with: [ self writeCounterForHeader: aHeader. super visitHeader: aHeader ]. canvas newLine ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ and ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ createIdForHeader: aHeader | id | id := aHeader text. id := id asLowercase. "replace banned characters with dashes" id := '[^0-9a-z\-]' asRegex copy: id replacingMatchesWith: '-'. "merge multiple dashes" id := '-{2,}' asRegex copy: id replacingMatchesWith: '-'. "remove dashes from beginning/end of the id" id := '^-|-$' asRegex copy: id replacingMatchesWith: ''. ^ id ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Strictly speaking HTML 5 is very permissive with the value of id, but the question is whether we really want to permit everything. E.g. unicode in url is always asking for trouble. Thanks, Peter

interview on .Net Rocks! about Moose, humane assessment, Pharo and GT
by Tudor Girba Aug. 1, 2015

Aug. 1, 2015

Hi, I had the pleasure of giving an interview for the .Net Rocks! podcast. It was quite fun and I managed to mention Moose, humane assessment, Pharo and GT in 45 minutes. It was not as smooth as a presentation but I still think it's a useful advertisement. Let me know what you think, and feel free to promote it further: https://dotnetrocks.com/default.aspx?showNum=1172 http://www.tudorgirba.com/blog/dotnetrocks-interview-moose-humane-assessmen… Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"

Download only metainfo about mcz when selected
by Jan BlizniÄenko Aug. 1, 2015

Aug. 1, 2015

Hello Lots of times I want to take a quick look at what is new in external packages I use, therefore I open repository in monticello, click at mcz and look at commit note. However, most of the times I want just to look at it, the commit time, author and note, not load whole mcz with its content. I would like to ask whether it is possible to change way of loading mcz in way that it would download only these metaatributes of mcz when browsing them (when I select mcz in list of all mcz of package) and download whole mcz only when I do load/change/merge etc. Jan -- View this message in context: http://forum.world.st/Download-only-metainfo-about-mcz-when-selected-tp4837… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

VM Crash after adding ram
by Ramon Leon Aug. 1, 2015

Aug. 1, 2015

So I've just upgraded my Ubuntu 14.04 machine to 16 gig of ram from 8 gig of ram and suddenly I can no longer start my Pharo VM; I don't understand why adding ram would make the vm stop working, I've been using it for year without problems. Can anyone interpret this: no objects after the end of memory pharo VM version: 3.9-7 #1 Tue May 6 08:26:29 UTC 2014 gcc 4.8.1 [Production ITHB VM] Built from: NBCoInterpreter
