Aconcagua Documentation
by Sean P. DeNigris March 19, 2015

March 19, 2015

Is there anything besides http://stephane.ducasse.free.fr/Teaching/CoursAnnecy/0506-M1-COO/aconcagua-… ? There are not many class comments and the tests were a bit overwhelming for me... Specifically I'm searching for anything built-in to present measures in the "most tidy" representation e.g. "125 dollars" instead of "12500 cents", "10 cups" instead of "480 teaspoons", etc. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Aconcagua-Documentation-tp4759781.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

by Blondeau Vincent March 17, 2015

March 17, 2015

Hello everyone, I am glad to announce the first version of the RProjectConnector, a binding between Pharo and R using NativeBoost. You can now call directly your R methods from Pharo: data := (1 to: 1000) collect: #yourself. res := (#acf asRFunctionWith: {data}) eval To use it, you should copy the R libraries near the Pharo VM (see the documentation on SmalltalkHub to see how to proceed) and Gofer it smalltalkhubUser: 'VincentBlondeau' project: 'RProjectConnector'; configuration; loadStable Don't forget to relaunch Pharo after the installation to be able to use the connector. The sources are available on Smalltalkhub: http://smalltalkhub.com/#!/~VincentBlondeau/RProjectConnector if you want to participate, just ask me!

Changes file size
by Esteban A. Maringolo Feb. 13, 2015

Feb. 13, 2015

I know we're on our way to get rid of changes, but meanwhile after installing my Metacello config I end up with an image of 40megs and a changes file of 140 megs!!! It doesn't load anything too esoteric: Glorp, Magritte, Seaside, Postgres, NeoCSV and my own packages. I can run PharoChangesCondenser condense, but it takes forever! (I started it 20 minutes ago and it's still running). Is there a way I can improve this situation? Esteban A. Maringolo

Installing GToolkit
by Evan Donahue Feb. 3, 2015

Feb. 3, 2015

Hello, I am trying to check out GTPlaygroundl, but I can't seem to get it working and was wondering if anyone had any idea what I might be overlooking. I download a new image with curl get.pharo.org | bash I run, from http://www.humane-assessment.com/blog/installing-gtoolkit Gofer new smalltalkhubUser: 'Moose' project: 'GToolkit'; configuration; loadDevelopment. #GTImageSetupCommandLineHandler asClass new activate It loads for a while and then the image closes. When I open it again the background is white and my settings have been wiped. The playground does appear, but it doesn't seem to work properly (there seems to be no way to advance the miller columns). Am I looking at the wrong installation information? Thanks, Evan

How do I save contents of Workspace into a collection?
by Frank Church Jan. 31, 2015

Jan. 31, 2015

Hi guys, My images are gathering a number of Workspaces whose contents I don't want to delete. I want to create a collection of Workspace contents along this defintion: Description Date Category Content (the actual text in the Workspace). In the final version I would like to be able to select a workspace and simply click a button or a menu item and get a dialog where I can enter the Description, Category and Date with the Workspace contents automatically captured into a text box. Copying and pasting the contents would be okay to start with. Filing it out would be another aspect later. What kind of array would best suited to the task? There is quite a number of them depicted here: http://www.jmcsweeney.co.uk/computing/m206/collections_intro.php What could be the best way to go about it? For those who are curious I am experimenting with the original ideas of Smalltalk where a computer user would do everything in Smalltalk workspace/desktop. I am intrigued by the possibility and somehow it seems eminently doable. -- Frank Church ======================= http://devblog.brahmancreations.com

if Pharo is key for you
by StÃ©phane Ducasse Jan. 18, 2015

Jan. 18, 2015

Hi guys if Pharo is key for you then you should ask yourself what you did for Pharo recently. Writing code, writing documentation helping closing bug entries, participating to the association, to the consortium... Pharo is not happening from spontaneous generation. Stef

Metacello does not load the expected version from ConfigOf
by Usman Bhatti Jan. 13, 2015

Jan. 13, 2015

Hi all, I am trying to load a specific version of PetitParser in a Moose image. A Moose image comes with the latest development version of PetitParser. So, I am trying to downgrade to an older version. So, when I load the version manually, older versions of the packages are loaded: (ConfigurationOfPetitParser project version: '1.51') load But when I try to load the same version within my ConfigOf the expected packages are not loaded and list of the PetitParser packages loaded remains unchanged. Here is how my baseline looks like: ConfigurationOfDummyParser>>baseline01: spec <version: '0.1-baseline'> spec for: #'common' do: [ spec blessing: #'baseline'. spec project: 'PetitParser' with: [ spec className: #ConfigurationOfPetitParser; versionString: '1.51'; repository: 'http://smalltalkhub.com/mc/Moose/PetitParser/main/' ]. ]. I also tried creating a version but it didn't help. ConfigurationOfDummyParser>>version10: spec <version: '1.0' imports: #('0.1-baseline' )> spec for: #'common' do: [ spec blessing: #'stable'. spec description: 'version 1.0'. spec author: 'usmanbhatti'. spec timestamp: '12/19/2014 16:35'. spec project: 'PetitParser' with: '1.51'. ]. I also had a look at the package the configuration tries to load and the list shows correct packages to be loaded (see screenshot). Does anyone have an idea what may be problematic in my code or that of Metacello? I am attaching the code of my ConfigOf for a Moose image. Thanks in advance. Usman[image: Inline image 1]

Extending GTSpotter
by Edward Povazan Jan. 10, 2015

Jan. 10, 2015

Hello, I am having a blast with GTSpotter - itâs the missing link for me, just one step to ask a question from Pharo. Keeps the flow going! Being new to the innards of Pharo, Iâve decided to try something. I would love documentation in GTSpotter. For example, I am interested in how packages are organized in Pharo. Cmd+Enter: âPackage' I get a list of package type classes. Cmd+Sh+Right Arrow. Now I see all the classes in the Classes category ... PackageInfo, PackageOrganizer, GRPackage, RPackageOrganizer - all interesting candidates in my exploration. But now I need to browse into each, look at the docs, then bring back GTSpotter, navigate to the last context with History, and repeat. More than one step. So I am going to try: - when showing all items in classes and methods categories, add a little [d] tag to the end of the item text to indicate if there is documentation for that item (class/instance or method docs) - Cmd+Sh+Right will display the docs. Is this doable within the current framework? If so, I am going to chip away on this. Thanks, -Ed

[ANN] Spec documentation in PFTE book finished
by Johan Fabry Jan. 2, 2015

Jan. 2, 2015

Hi all, I am happy to announce that Ben and I finished the documentation of Spec for the Pharo For The Enterprise book. This documentation is up-to-date with the latest version of Spec, and is focused towards people wanting to use it and even extend it (in contrast to the academic papers which are â¦ academic ;-) ). I hope that this text will help all the people that are building UIs in Pharo, and it will clear up any doubts that they may have. The chapter is available in source form from the GitHub project of the PFTE book: https://github.com/SquareBracketAssociates/PharoForTheEnterprise-english The easiest way to read the chapter is from the continuous integration server, which produces a html file of the chapter here: https://ci.inria.fr/pharo-contribution/job/PharoForTheEnterprise/lastSucces… (The same server also produces pdf and markdown files, but there are some strange artifacts there, currently. I guess this will be cleared up in the future) We tried our best to make it understandable and complete, but if you have any doubts or comments please do not hesitate to let us know !! Ben prefers Github apparently, but if you are oldskool like me you can also send a mail (privately or to the mailing list). Now it's time to build some cool user interfaces! :-) ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile
