Constrained variable width of Plaground/Inspector panes
by Peter UhnÃ¡k Oct. 30, 2015

Oct. 30, 2015

Hi, is it possible to programatically change the width of Playground/Inspector panes? Currently if I want one pane bigger I have to resize both which wastes a lot of space (I need to resize twice as much). eg: I wouldn't mind having a "special playground" just for this particular use case. There is also Roassal Easel â However I would like to have the code on a side rather than underneath because code is tall, not wide. Thanks, Peter â

TestAsserter>>assertCollection:hasSameElements:
by Peter UhnÃ¡k Oct. 30, 2015

Oct. 30, 2015

How practical it is to do set-based comparison in TestAsserter>>assertCollection:hasSameElements: ? For example #(1 1 2) has same elements as #(1 2) which may make sense for sets, but not for bags. The main reason I was using it is that in tests the expected collection may be created by hand, which means it is very often an array #(...), { ... }, while models very often return OrderedCollections (at least in my case). So my question is --- how to compare collections irrespective of type, and possibly of order? A) always convert the actual collection toanArray B) change difference: behavior for non-sets (ton of work with catastrophic consequences) C) extend TAssertable with new methods like #assertElementsOf: actualCollection equals: expectedCollection #assertUnorderedElementsOf: actualCollection equals: expectedCollection C.a) directly in Pharo/SUnit C.b) in independend SUnit-Extensions repository/project C.c) just in my project D) stop discussing non-problems Thanks, Peter

What is your preferred way for storing ByteArray's as text?
by Esteban A. Maringolo Oct. 30, 2015

Oct. 30, 2015

Hello all, As some already know I'm working in the new GLORP port from VW to Pharo. And as part of minor modifications I'm making to the code, I'd like to know what is your preferred way of storing ByteArrays as text representation/CLOB, etc... Option A) The printString of ByteArray, it is #[23 12 253 ...] Option B) A Base64 encoded version of the ByteArray Option C) Some other encoding I posted the same question in the #databases channel at Pharo's Slack team ( https://pharoproject.slack.com/archives/databases/p1446130304000022) Regards!

Attempting Pharo Book #3 WebApp Example on a 64-bit iMac
by Bruce Prior Oct. 30, 2015

Oct. 30, 2015

My problem was that I chose a 64-bit Ubuntu OS when I signed up with the ISP, Digital Ocean. So I started another Droplet at DO and set it up with an Ubuntu 32-bit system. All is well now and everything down to the end of sec. 12 in Sven's tutorial works for me. Now I'll look at Deploying For Production. Many thanks to Sven and Damien for their comments, and to Sven for his fascinating tutorial. Bruce

How to add a keyboard shortcut to Rubric?
by Johan Fabry Oct. 29, 2015

Oct. 29, 2015

Hi all, I am trying to add a keyboard shortcut to a RubTextEditor. I have tried different ways but nothing seems to work. I have even tried modifying buildShortcutsOn: at class side to include the extra shortcut but it does not have any effect at all. Ideally Iâd take an existing instance and add the keyboard shortcut there, but if that is impossible Iâm willing to make a subclass just to get this extra shortcut. Can anybody give me pointers? ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile

Attempting Pharo Book #3 WebApp Example on a 64-bit iMac
by Bruce Prior Oct. 29, 2015

Oct. 29, 2015

I worked my way through Sven van Caekenberghe's excellent tutorial on building and deploying a web app on Digital Ocean's cloud server. All went well at first, even though Digital Ocean didn't offer a Mac option (I picked Ubuntu Linux). I skipped the Tests and Configuration parts of Sven's tutorial in order to get to the deployment part faster. I thought I could come back to those parts. I was able to get SSH command line access to the new server and loaded Pharo using curl (See Sven's Section 12.3). But when I went to test the setup using # ./pharo Pharo.image printVersion I got an error saying pharo not found even though it was there in the pharo-vm directory. I suspect that my attempt to do all this on an Apple iMac is the problem. Has anyone else tried using a Mac with Digital Ocean?

Would smart variable ordering improve performance?
by Alexandre Bergel Oct. 27, 2015

Oct. 27, 2015

Hi! It is known that increasing data locality is a good way to benefit from CPU caches. There has been some effort from the IBMâs JVM crew that aligns some frequently accessed variables at a particular offset to improve accesses. Would this approach works in Pharo? Other similar situation: will the expression âObject new yourselfâ be faster if the object (i.e., result of Object new) is physically close to the class Object in memory? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Does anyone use Garage with an oracle database? Maybe someone that develops on Mac OS? I would be interested in the best way to compile and install libraries in order to use it from pharo. Norbert

Pharo family update
by Adam Oct. 27, 2015

Oct. 27, 2015

Hello, I just updated drawing of projects around Pharo. Main idea is to guide people (new users of Pharo) through fields of interests - something they might be looking for. I choose these 10 fields devided into some specific subjects. Somewhere it is too detailed, while elsewhere it is too fuzzy - it is just showing image of Pharo I have in my mind. It should help people to: - identify important classes in Pharo, - select right project, - understand what is application, tool or framework, - see what is allready inside main Pharo image. I would like to add links pointing to part of books or to videos where specific projects are used. And maybe a star symbol for very important or enterprise ready projects. As You can see I left few subjects empty. Maybe someone can help me fill this. But I will be happy for any type of correction - changing fields of interest, subjects, adding/removing projects etc... I prepared textual version on github - but right now it is not coherent with the drawing (I will correct this if needed). Adam.
