Howto BaselineOf
by Hilaire July 23, 2018

July 23, 2018

Hi, I have this enclosed BaselineOfDrGeo which I think contains mostly all I need. How should I load it? This code bellow does not work: (BaselineOfDrGeo project version: #development) load. By the way the PharoDebug log file is not recorded along the image, but at the user root directory. Is itÂ wished? ... -- Dr. Geo http://drgeo.eu

Set Rounding mode for IEEE floating point operations
by Steffen MÃ¤rcker May 29, 2018

May 29, 2018

Hi, is there any way to set the rounding mode for IEEE floating point operations? Maybe something like > Double roundToMinusInfWhile: [... code goes here ...]Double > roundToZeroWhile: [... more code here ...] If not, is it possible to add this behavior, e.g., via a custom primitive? Best, Steffen

Restoring a class via Epicea didn't recompile a reference?
by Tim Mackinnon May 17, 2018

May 17, 2018

Hi - I think I had this issue a long while back, but I just hit it again (desperately trying to get back into Pharo again)â¦ I was trying out Willow - and had a method like this: initializeContainerView | behaviorDetails scopeSelection | behaviorDetails := IdentifiedWebView forDivNamed: 'behavior-details' containing: WPPagerDutyUserDetailsView new applying: [ :div :constants | â¦. Where I had a class reference to: WPPagerDutyUserDetailsView, I deleted that class thinking I didnât need it and then spotted the above method referenced it and so I brought it back via Epicea. However when I ran my Willow Application, my web page was showing an error message âError, ObsoleteClassWPPagerDutyUserDetailsView does not implementâ¦.â - essentially it seemed like this method was referencing the class I had deleted and not the one I had restored. When I went back to this method and simply reserved it, everything worked properly. I recall Marcus (at the time) mentioning that the Opal compiler was supposed to detect these kinds of changes and rebind things properly - but it seems that this isnât the case - or potentially restoring something from Epicea subverts this? I can raise a bug if its genuine - but Iâm just musing on this at the moment? Tim

Spec on Moose 6.0 error: MessageNotUnderstood: ToolDockingBarMorph>>popUpOwner
by Offray Vladimir Luna CÃ¡rdenas May 15, 2018

May 15, 2018

Hi, I'm getting this error while trying to prototype some interface with Spec on Moose 6.0: MessageNotUnderstood: ToolDockingBarMorph>>popUpOwner it happens anytime that I'm using displaying a MenuModel and I go to the menu items. I imagine that the menu item is complaining about a lacking pop up message. How can I solve this? Thanks, Offray

#ast vs. #parseTree
by Sean P. DeNigris May 9, 2018

May 9, 2018

Why does CompiledMethod understand both? They are in the same protocol, produce the same kindOf result, and neither has a method comment! :/ (Pharo 4.0) ----- Cheers, Sean -- View this message in context: http://forum.world.st/ast-vs-parseTree-tp4893074.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Showcasing Pharo, Roassal and Grafoscopio at re:publica 2018
by Offray Vladimir Luna CÃ¡rdenas May 8, 2018

May 8, 2018

Hi, I will be showcasing Pharo, Roassal and Grafoscopio at re:publica 2018, next week. As you may know, re:publica[2] is one of the most important and visible media & digital culture conventions in Europe and is a good scenario for the Pharo community.Â You can find details about my participation at [1] [1] https://18.re-publica.com/en/session/data-clinic-twitter-data-selfies-data-… [2] https://18.re-publica.com/en I will be making intensive refactoring on the Dataviz package to create some usual and unusual data visualizations from data exported from Twitter, so I may be more active those days in the Discord and mailing list channels, is some questions arise. Thanks in advance for the Pharo communities support. I wouldn't be able to be there without it. Cheers, Offray

Histogram for files dates and sizes
by Offray Vladimir Luna CÃ¡rdenas May 6, 2018

May 6, 2018

Hi, I'm making a histogram of files that have the naming convention |YYYY_MM.js|, for year and month info. The image below shows what I get until now: By the way, you can run this example by loading and updating the Dataviz package [2] from [3] [2] http://mutabit.com/repos.fossil/grafoscopio/doc/tip/Packages/Dataviz/readme… [3] http://ws.stfx.eu/OUEYE943HV3Q I would like to have bars for every year of a file name in a different color (I imagine that using |#distinctColorUsing:| ) and ticks on each year. I'm seeing some examples in the image and in http://agilevisualization.com/AgileVisualization/Roassal/0104-Roassal.html, but I wonder if there is a more mature and already existing RTObject for this kind of work. Also I would like to show Y axis scale using size of files in a human friendly format (160 Kb instead of 160000.0 and so on). Any help or pointers on this is greatly appreciated. Cheers, Offray

[Voyage] How to declare an instance variable as transient?
by sergio ruiz May 3, 2018

May 3, 2018

Hi, all.. I have an instance variable that I donât want to save as part of the full project. I was wondering how to set this up. The documentation says: Lastly, attributes can be excluded from storage (and hence retrieval) by re- turning a VOMongoTransientDescription instance as the attribute descrip- tor. But I am not sure how to set this up in my class. thanks!Â ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.codeandmusic.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

[Ann] Iceberg 0.7.3
by Guillermo Polito May 3, 2018

May 3, 2018

Hi all, We just introduced Iceberg 0.7.3 into Pharo. This new version solves several issues people had when contributing to Pharo in general and others. I've made a screencast on how to contribute to Pharo, and added some tutorial and glossary in Iceberg's wiki. Below the links and the changes log. Thanks for making your issue reports ^^. We will schedule a backporting to Pharo6.1 in a couple of weeks, once we have another iteration. Cheers, Guille # Contribute to Pharo with Iceberg 0.7.3 - wiki page: https://github.com/pharo-vcs/iceberg/wiki/Contribute-to-Pharo-with-Iceberg-… - Screencast: https://www.youtube.com/watch?v=PK2yCu2rWCc&feature=youtu.because This screencast shows how to use Iceberg 0.7.3 to contribute to latest Pharo 7, by cloning from scratch your own (potentially outdated) clone. This video will guide you through: - solve the "Missing local repository" by cloning - solve the "Fetch required" that appears because the fork is out of date - solve the "Detached working copy" by creating a new branch - use the pharo plugin to create an issue branch - make some changes, commit them and push them to your fork - make a pull request If you already have a clone, you can just import an existing repository from your disk. The rest of the instructions should be the same. If you don't have a fork, create one before doing anything else. New videos to come with more explanations. # Iceberg Glossary https://github.com/pharo-vcs/iceberg/wiki/Iceberg-glossary # 0.7.3 ChangesLog - #693 <https://github.com/pharo-vcs/iceberg/pull/693>: fixing problem when the announcement of changes in a package is nil.

Pharo 7 image, some more size reducation
by Hilaire May 2, 2018

May 2, 2018

Hi, Pharo7 has proven to be a reliable host for Dr. Geo, and thank you for your advices and helps. In the past weeks several screenshotsÂ were posted on DrGeo twitter, all based on P7 built. Many notable tools or frameworks like Tonel, Glamour tool kit, Calypso, Metacello, VM builts have proven to be reliable. IÂ am now at the point where I am thinking about a new public release. Before that I want to squeeze a bit more the image. It is now about 36MB, and I am looking at some advices to shrink it a bit more. What is done is described there[1]. For example is it possible to remove Nautilus? A temporary built can be fetched from there[2], tests and feedbacks are also greatly appreciated. Thanks Hilaire [1] https://bazaar.launchpad.net/~drgeo-developers/drgeo/trunk/files/head:/src/… [2] https://www.dropbox.com/s/a4wb7c6od4fdl9k/DrGeo.app-18.06a.zip?dl=0 -- Dr. Geo http://drgeo.eu
