Spec vs Brick vs Glamour vs Morphic vs WTF?
by Brad Selfridge July 6, 2016

July 6, 2016

Ok! I'm really confused. I'm wanting to write new GUI and I have no idea which framework to use. There is very little documentation on any of these and I don't see a clear cut statement of direction as to where the Pharo community is heading. Can someone please advise? Thanks. ----- Brad Selfridge -- View this message in context: http://forum.world.st/Spec-vs-Brick-vs-Glamour-vs-Morphic-vs-WTF-tp4905178.… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Pharo Mooc
by Arie van Wingerden July 6, 2016

July 6, 2016

âHi, on the main Pharo page I see Pharo Mooc mentioned. Obviously I am too late to join. Will there be a similar course in the (near) future? Are there other (video) courses available? I checked Udemy and O'Reilly, but alas, Smalltalk isn't that popular anymore nowadays... Thx, Arie

a bug in Spec that I wont fix
by Hartmut Krasemann July 6, 2016

July 6, 2016

Hi to whom it concerns. Working with Spec (Pharo 4.0) I needed to dynamically update the ButtonModel BalloonHelp. Since it did not work, I searched and found that ButtonModel initializes helpHolder again thus removing the changeBlock set in AbstractWidgetModel. The statement < helpHolder := nil asValueHolder. > in ButtonModel>>initialize has to be removed. Since I do not yet work with Pharo 5 I propose that somebody working with Pharo 5 would fix this.

How to deploy a Pharo app?
by Arie van Wingerden July 6, 2016

July 6, 2016

Hi, I searched for this, found things, but they ended up with broken links ... Is there a recipe for deploying a desktop Pharo app? What I mean is: - no "world" windows visible - autostart using a specific message - etc. Thanks! Arie

How do I convert a FileTree project to Metadataless GitFileTree project?
by Dale Henrichs July 5, 2016

July 5, 2016

Thierry, I think I tried the obvious: 1. open existing repository with gitfiletree:// 2. reload all packages from gitfiletree repo and remove old filetree:// repo from each package 3. edit .filetree and add `"Metadata" : "false"` but when I save a package I continue to get metadata created ... I even tried removing and adding the repo after editting the .filetree file .... I have a handful of additional random things that I will try, but I think it is also time to find out the proper technique:) I want to gain experience with GitFileTree; test out the Metacello Cypress mode; and perhaps honor the `"Metadata" : "false"` in the GemStone version of FileTree ... With a short time of usage, I would really like to be able to save all of the packages in a project (including the BaselineOf) in one commit ... I often have multi-package units of work that really should be committed together and of course if a method is moved across a package boundary, the independent commits don't allow git to recognize the move as a "rename" ... Also I'm hoping that in metadataless mode I stop scanning the entire known repository universe for package versions that will not be found anywhere but in the repositories that I've explicitly associated with the the package itself:) Thanks, Dale

Hi, is there any plan for NeoNumberParser do add localization support? e.g. NeoNumberParser new thousandsSeparator: $,; "common in us data" parse: '12,230' => 12230 NeoNumberParser new decimalSeparator: $,; "common in eu data" parse: '12,230' => 12.230 Thanks, Peter

can pharo change encoding of a file?
by Peter UhnÃ¡k July 5, 2016

July 5, 2016

Hi, is there a way to reencode a file from within Pharo? e.g. I have a file in CP1250 encoding and I want to change it to UTF-8. In linux I would do something like "recode cp1250..utf8 file.txt". But can Pharo do that natively, or do I need to defer to the system with FFI/OSSubprocess? Thanks, Peter

[UFFI] Getting an array of opaque structures filled
by Julien Delplanque July 4, 2016

July 4, 2016

Hello everyone, I have a question about the UFFI API. I have the following function: ssize_t libusb_get_device_list (libusb_context *ctx, libusb_device ***list) where libusb_device is an opaque structure. I made a type mapping "ssize_t" -> "int" and an object inheriting from FFIExternalObject for the "libusb_context" (others methods using it are working). I can not find how to get an array filled with libusb_device using UFFI from Pharo. :-( Thanks in advance, Julien

SIGPLAN Programming Languages Mentoring Workshop @ SPLASH'16 Amsterdam, The Netherlands (part of SPLASH 2016) Tuesday, November 1st, 2016 http://2016.splashcon.org/track/splash-2016-plmw We are pleased to invite students interested in programming languages to the Programming Languages Mentoring Workshop (PLMW) at SPLASH. The goal of this workshop is to introduce senior undergraduate and early graduate students to research topics in programming languages as well as provide career mentoring advice. We have recruited leaders from the programming languages community to provide overviews of current research topics and give students valuable advice about how to thrive in graduate school, search for a job, and cultivate habits and skills that will help them in research careers. This workshop is part of the activities surrounding SPLASH, and takes place the day before the main conference. A key goal of the workshop is to make SPLASH more accessible to newcomers. Through the generous donation of our sponsors, we are able to provide travel scholarships to fund student participation. These travel scholarships will cover reasonable travel expenses (airfare and hotel) for attendance at both the workshop and the following main three days of SPLASH. The workshop is open to all. Students with alternative sources of funding for their travel and registration fees are welcome. In particular, many student attendance programs provide full or partial travel funding for students to attend SPLASH 2016. More information about student attendance programs at SPLASH is available here: http://2016.splashcon.org/attending/students Application for Travel Support: The travel funding application is available from the PLMW webpage. The deadline for full consideration of funding is August 15th, 2016. Selected participants will be notified by September 1st. Organizers: Sandrine Blazy, University of Rennes 1 Ulrik Pagh Schultz, University of Southern Denmark
