Comparison for SequencableCollection
by webwarrior Aug. 4, 2015

Aug. 4, 2015

I was surprised when discovered that in Pharo comparison is not defined for lists, arrays and similar datastructures. Because in almost every programming language (F#, Python, Javascript just to name few) you can compare lists, arrays, etc. By convention, the ordering is lexicographical, just like in strings. It took little time to add needed methods to SequencableCollection, but I think its better to have them in core library (core image, or how do you call it?). -- View this message in context: http://forum.world.st/Comparison-for-SequencableCollection-tp4840704.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

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

open street map example

Aug. 3, 2015

Hi! Some of you have an interest in visualizing graphs on top of open street maps. Together with Hilaire we made a small example: -=-=-=-=-=-=-=-=-=-=-=-= | v map data b d whiteBackground london elementsAndEdges | v := RTView new. v @ RTDraggableView. map := RTOSM new. v add: map element. "Place to set the data and center the camera" london := 51.507222@ -0.1275. "Some arbitrary data" data := ((1 to: 500) collect: [ :i | 50 atRandom - 25 ]) cumsum. "We build the graph" b := RTGrapher new. b extent: 100@30. d := RTData new. d noDot. d connectColor: Color red. d points: data. b add: d. b axisY labelFontHeight: 6; color: Color red; title: 'Sale'. b axisX color: Color red; noTick; title: 'country'. b build. elementsAndEdges := b view elements, b view edges. "We create a white background" whiteBackground := (RTRoundedBox new color: Color white trans; borderRadius: 10) element. v add: whiteBackground. v addAll: elementsAndEdges. RTNest new on: whiteBackground nest: elementsAndEdges. whiteBackground translateTo: (map latLonToRoassal: london). v canvas camera translateTo: (map latLonToRoassal: london). v canvas camera noInitializationWhenOpen. v canvas camera scale: 1.5. v -=-=-=-=-=-=-=-=-=-=-=-= Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Pillar hyperref and refs numbering
by Peter UhnÃ¡k Aug. 3, 2015

Aug. 3, 2015

Hi, I have two questions: 1. Would it be possible to add \usepackage{hyperref} to Pillar pdf output? Because currently all links are invisible (well, not invisible but they look like regular text so if the). So if you have sentence like "Then create a directory named "pharo-vm" and unzip the VM for windows that you can get on the pharo website (windows virtual machine) ." (Section "installing pillar on windows." nobody will notice that it's a link). Having hyperref for print doesn't make sense but if people are viewing it on their computer it's useful. 2. Why does HTML and PDF numbering differ? For example the first figure in HTML is "15.1", whilst in PDF its "1.1". This is further exemplified in the second sentence of the chapter "Pillar is currently used to write the Enterprise Pharo book and other projects (see Section 1.1)." or "Pillar is currently used to write the Enterprise Pharo book <https://github.com/SquareBracketAssociates/EnterprisePharo> and other projects (see Section 15.1.2 <https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessf…> )." Where in PDF it's actually referring to the whole chapter instead of the proper part. But this may be result of the subsections not being numbered (unlike html, which numbered is). Thanks, Peter

Garage, Glorp, PostgreSQL and Cursors
by Tommaso Dal Sasso Aug. 3, 2015

Aug. 3, 2015

Hello, I was trying the version of Glorp ported to Garage, and I must say it runs smoothly, nice job! I am reading large amount of data from a Postgres db, and I was curious about the use of cursors. I remember that the old version of Glorp for Pharo did not support cursors in Postgresql, has this changed in Garage? I tried to run some tests, using a query like: (Query readManyOf: MyClass) collectionType: GlorpCursoredStream; yourself. but with a large number of rows (~300k), the whole image crashes. Is this still not supported, or am I doing something wrong? Thanks, Tommaso

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.
