How to play audio files with Pharo ?
by Dimitris Chloupis Nov. 25, 2015

Nov. 25, 2015

I want a cross platform solution for playing audio files for my project ChronosManager. By cross platform I mean MacOS, Ubuntu and Windoom. I assume that playback of MP3 is out of the question ? Any ideas /suggestions ?

And I would like it to do: ... pdflatex output.tex bibtex biblio pdflatex output.tex pdflatex output.tex ... Is it possible to override the default LaTeX's compilation script from pillar.conf?

Nov. 24, 2015

Hi, is it possible to have table with multiline cells in Pillar? For example in markdown I can embed a piece of HTML, unfortunately Pillar requires {{{html: to start at a new line which doesn't work with tables. Is there another solution? Thanks, -- Peter

piping output from shell process to transcript
by Peter Uhnak Nov. 24, 2015

Nov. 24, 2015

Hi, how can I pipe output from PipeableOSProcess to Transcript? I tried doing: (PipeableOSProcess command: 'my-command.sh') outputOn: Transcript. However `#outputOn:` doesn't send `#endEntry` so I don't see anything, and even if it would, the output is delivered there at the end anyway. I would like to see the live result of the running commands. Thanks, -- Peter

About profiling code
by Dimitris Chloupis Nov. 22, 2015

Why [CheckboxMorph new] timeProfile returns nothing ? I also tried it in the profile tool without the block and still displays nothing . Is there any special requirement for profiling code ?

Extracting *.tar.gz file in Pharo 5
by Juraj Kubelka Nov. 21, 2015

Nov. 21, 2015

Hi, is there a way to extract *.tar.gz files using plain Pharo 5 image? Without loading extra packages? It could be OS dependent. Maybe calling external linux tar application. I have done it with ExternalUnixOSProcess object, but it is not standard part of Pharo 5. Thanks for any comment. Juraj

Stuck at lookup implementation in "Building ObjVlisp" tutorial
by Edouard Delbar Nov. 20, 2015

Nov. 20, 2015

Hello everyone, I'm new on this mailing list, this is my first mail :-) I'm a student from University of Lille (France). I'm studying this tutorial (I'm using Pharo 4 but it seems not to be a problem):Â http://sdmeta.gforge.inria.fr/Teaching/ObjVLisp/ObjV.pillar.pdf. I'm working with the "ObjVLispSkeleton-StephaneDucasse.1" image loaded from this repository: MCSmalltalkhubRepository owner: 'StephaneDucasse' project: 'ObjVLispSkeleton' user: '' password: '' I'm stuck at "Method Lookup" p11. First, it seems that unit tests "testNilWhenErrorInLookup" and "testRaisesErrorSendWhenErrorInLookup" are not provided, thus I'm not sure that I'm working with the right image (everything was fine until p11 though). Then, the "lookup: selector" is not provided neither. While there is another method named "lookup: selector from: anObjObject", I can't figure out what I'm supposed to do with the second parameter. Here is what I would do: lookup: selector "look for the method named <selector> starting in the receiver.Â The lookup is done for a message sent to <anObjObject>. self is an objClass" ^ self objMethodDict at: selector ifAbsent: [ self objSuperclassId ifNotNil: [ self objSuperclass lookup: selector ] ] Could someone tell me if this implementation is correct? If it's correct, what do you think the second parameter is for?Â Moreover, do you think I'm working with the right image? Thanks. - Edouard

[ANN][EPHESTOS] ChronosManager a time managment tool
by Dimitris Chloupis Nov. 19, 2015

Nov. 19, 2015

Hello people, as you may or may not remember I shared a sneak peak of my latest tool for my project Ephestos , a time managment tool I call ChronosManager. This tool is important for me for 2 reasons 1) Its my first venture into the island of Custom GUIs with Morphic here is how it looks like [image: chronosmanager01.png] The goal of this tool is to be a next generation for the Pomodoro tool that was available through Catalog/Configuration Browser. 2) My goal is to expand this tool way more than you see into a more advanced time management tool , with several ideas I will reveal in each release. So for those not familiar with the Pomodoro technique , its quite simple really, the idea is that its best to work taking regular brakes to help relax the mind but also to keep careful track of time to keep away distractions. So we divide our work into tasks , a number of tasks make a daily goal , each task is divided to the actual work time (time limit) and time to relax (brake limit) . Bare in mind this is a version 0.1 it may contain bugs and issues, right now I forgot to implement a display for the completed tasks but that will be added in the next few days. The GUI you see in the image is fully expanded the secondary panel can be hidden and the whole GUI can be minimised into a regular taskbar button like all pharo windows but instead of displaying the name of the app it displays useful info like timer and stopwatch time so you can keep it minimised without taking any space from your GUI. The concept of timer and stopwatch is just about how you want to display the time passed for each task, it makes no diffirence which one you choose the one displays remaining time (timer) of timelimit period or brakelimit period depending in what period you currently are and stopwatch its just moves time forward with similar workflow. Installation --------------------- Installing is dead easy just open configuration browser/ catalog browser and load it from there and it will also add a menu entry at the world menu. Hope you like it much more to come :)
