Nesting Builders in Roassal
by Evan Donahue April 9, 2016

April 9, 2016

Hello, I am working with Roassal and trying to write a cell-layout builder that uses RTPieBuilders internally as its nested objects. The nesting docs cover nesting RT elements, but not builders. The composition docs cover composing builders, but not nesting them. I have a partial solution, but it is getting increasingly hacky, to the point where it may be easier to just duplicate the piebuilder code in my builder. Before I go down that road, I wanted to check if there was a more natural way to nest builders. Below is a mashup of the Roassal Examples Nesting and Pie Chart builders that gives the basic flavor of what I am trying to accomplish. Notice that I am creating new PieBuilders every time, running them, and extracting their createdElements for my layout. This works well enough, but if I then want to normalize global properties so that all pie slices with the same property get the same color, I have no way to coordinate the newly generated PieBuilders, as each possesses its own normalizer. Likewise, if I have a global PieBuilder, its internal state gets trampled with each iteration. I figured there was likely an easy way to compose builders that I didn't know about, so I thought I would ask. | v es b | v := RTView new. es := RTEllipse elementsOn: RTShape withAllSubclasses. v addAll: es. RTNest new for: es add: [ :group :model | b := RTPieBuilder new. b objects: RTShape withAllSubclasses. b slice: #numberOfMethods. b normalizer distinctColor. b view: v. b build. group addAll: b createdElements. ]. RTCellLayout new lineItemsCount: 8; on: es. v Thanks, Evan

Tables in Pillar
by phil＠highoctane.be April 3, 2016

April 3, 2016

How is one doing a cell with content wrapping on multiple lines? With the | X | Y | abcd | some very long text that should be wrapping but apparently doesn't. So it is very annoying when one attempts to describe a long thing, which is one purpose for a table. I get one single line for each entry. How to do that? TIA Phil

[ANN] OS-Linux-CentOS
by Torsten Bergmann April 1, 2016

April 1, 2016

Hi, the OS-xxx series with (so far) - OS-Windows - OS-Linux-Ubuntu - OS-Unix - OS-Raspbian now has a new member called "OS-Linux-CentOS" which is more or less an adopted/customized pendant to "OS-Linux-Ubuntu". Project page is at http://www.smalltalkhub.com/#!/~OS/OS-Linux-CentOS Ready for Pharo 5. As ever you can load from Catalog tool or directly by entering "CentOS" into the Spotter search tool.

[ANN] Search and open Unix man pages in Pharo (using OSUnix project)
by Torsten Bergmann April 1, 2016

April 1, 2016

I added the possibility to search and open Unix man pages (commands, functions and header files) directly from Pharo Spotter. You will find it in the updated version of my OSUnix support package in catalog (Pharo 5) https://www.youtube.com/watch?v=81eehVO14KU Have fun T.

Re: [Pharo-users] OpenGL project
by Thibault Raffaillac April 1, 2016

April 1, 2016

> Can you include a proper build script? Yep sorry, here are the steps I used to make it run on OSX: $ brew install glfw3 $ cc demo.c -lglfw3 -framework OpenGL For other systems the doc is hopefully detailed enough (http://www.glfw.org/docs/latest/build.html) > Why do you say ?porting NBOpenGL?? Is it just a matter of rewriting the > native calls with the new FFI system? NBOpenGL functions were generated automatically from NBGLGenerator, so I need to get used to the tool beforehand. It looks like a lot of work was put into this, can I find a paper about it? Also, IMO this all looks too complex. My point in limiting to ES 2 is not just removing functions, I want to make it look simple like the C demo! Thibault

[ANN] OS-Windows 2.1 project updated for Pharo 5 (NB to UFFI transition)
by Torsten Bergmann March 31, 2016

March 31, 2016

Hi, the "OS-Windows" package [1] from my "OS-xxx" Pharo goodies series [2] is providing better access to native Windows APIs and wraps Windows functionality for easier access/coding in Pharo (browser, console, processes, shell, window, GDI, ...). Some of you may know or use this package already. Up to the last provided stable version for Pharo 4 all my code and bindings were based on "old" NativeBoost (NB). With the transition away from NB over to new UniversalFFI (UFFI) within Pharo 5 it was necessary to port/migrate the code over to UFFI for all the OS-xxx projects. Work of the Windows port started when UFFI was still shaky (December) and in a separate repo [3]. It was not easy in the beginning, some headbanging against the wall and feeling like a crash test dummy was involved - basing the port on early UFFI code and without much documentation. Several UFFI issues had to be discussed with Esteban Lorenzano in private conversations on #slack: often leading to some updated UFFI versions afterwards and an updated worklog of Esteban [4]. In the Pharo spirit "step by step" all of this got analyzed, fixed, renamed, improved and integrated into latest Pharo 5 in the last months. Esteban was VERY VERY supportive and adopted UFFI for all the needs! ONCE AGAIN: A BIG THANK YOU, ESTEBAN!!! Long story short: I can now release "OS-Windows" again into the wild for Pharo 5: fully compatible, again with cleaner code, some more functionality and even more tests (from 77 to now 81) As ever it is easy to access: open spotter in Pharo 5 and load "OSWindows". Full docu is on the project page [1], the new version is fully compatible to the Pharo 4 version so there was no need to change a single line in the tutorial. ;) Have fun T.

Spec ListModel synchronization
by Rob Rothwell March 31, 2016

March 31, 2016

Hello, It's been a while since I tried out Pharo. I always struggled with Morphic UI's, but I noticed Spec and there seemed to be enough examples floating around that I thought I'd give it another try. Is Spec "here to stay?" Is it worthwhile to figure it out? It seems like with the developing possibilities of OSWindow-SDL2, one might use Spec to compose native widgets as well. My main question is about synchronizing domain changes with a Spec UI. For example, if I create an empty list of items: aList := OrderedCollection new. And create and open a ListModel that uses that list: aListModel := ListModel new items: aList; openWithSpec; yourself. I get a nice empty list. If I add an item to my list: aList add: 1. Then I need to update the list with another: aListModel items: aList. To see it show up. Alternatively (this seems wrong), I can add an item to the ListModel listItems directly: aListModel items: (aListModel listItems add: 1; yourself). Is that basically what you need to do to maintain synchronization between your domain list and the Spec UI representation of that list, or am I missing something? Thank you, Rob
