Re: [Pharo-users] A "with" construct like Pascal - easy to do, but is it terrible?

by Esteban Maringolo

Well... you have the cascading that provides you that. book1 title:'C Programming'; author: 'Nuha Ali '; subject: 'C Programming Tutorial'; book_id: 6495407. What I would like, sometimes, is the option to nest cascades, very much like the WITH DO construct of Pascal, Basic and others. But also I take this as a hint of some refactoring needed in my objects. Regards, Esteban A.

A "with" construct like Pascal - easy to do, but is it terrible?

by Tim Mackinnon

Iâve noticed that as weâve progressed there has been a move to more concise and fluid code - e.g. I quite like the new String streaming stuff e.g. ^ String streamContents: [ :stream | stream nextPut: â¦. ] So I was wondering why we donât have a construct like Pascals with to avoid Book1.title, Book1.author etc. (* book 1 specification *) With Book1 do begin title := 'C Programming'; author := 'Nuha Ali '; subject := 'C Programming Tutorial'; book_id := 6495407; end; I often find it a bit tedious with code like the following which then needs an instvar... self classes do: [ :class | | metaclass | metaclass := class metaclass. metaclass xxxx. mataclass yyyy. ] Iâm wondering why we donât have #with:do: class with: class metaclass do: [:metaclass | metaclass xxx. ] But when such things arenât there - there is usually a good reason and Iâm curious â¦ this said, there are all kinds of other such tricks (which I rarely use that I keep coming across).

Re: [Pharo-users] Stability of Pharo 7 vs 6?

by Tim Mackinnon

Just as a follow up to this - since not running fullscreen (as in not click on the green expand button in OSX) and having saved my image once - the stability seems to be much better. Iâve had an image running in the background for over a week now with no issue (whereas before it crashed in less than 24 hours) So I guess I should try another experiment with fullscreen but a saved image (my hypothesis is that its the initial saving that really makes the difference).

The smalltalk.org domain was registered to Peter William Lount. I've worked with him at some point.Â Maybe I could ask him if he plans to do anything with planet.smalltalk.org at all (we are still in contact) ?

Call for Mentors: Google Summer of Code 2019 with Pharo Consortium

by Jigyasa Grover

Hello Pharo-ers ! On behalf of the community, I would like to thank each one of you for their significant contribution which has led to our organisation being selected in Google Summer of Code (GSoC) yet again: https://summerofcode.withgoogle.com/organizations/6741777344626688/ Before the students start proposing projects and submitting proposals, I would like to invite all the experienced members to be a part of this amazing experience and mentor students to work on Pharo projects over the summer. Here is a GSoC mentor guide which one should definitely read to know more about roles and responsibilities: https://google.github.io/gsocguides/mentor/ Please volunteer to mentor any of the existing projects (Listed here: http://gsoc.pharo.org/) as soon as possible or propose fresh ideas for projects which shall help improve Pharo ! To add your own project idea to the list, visit http://gsoc.pharo.org/#adding-a-proposal. Looking forward to an appreciable representation from the Pharo community.

offers (deb and rpm packages included)

by Michael Zeder

Hi! I would like to make two offers: First, I know, deciding to be provocative can hurt. I did it int the hope that the released energy will be transformed in something good by the community, so apology for having been loud and insistent. Second, I felt oblidged to give at least a little thing back (since I use Pharo mostly in spare time). So, hey Linuxers! Whenever I set up a new system, I integrate Pharo Launcher into the desktop environment. I thought, I just built Debian .deb and RPM packages, for convient installation, on multiuser desktops. https://gitlab.com/mjz/pharo-linux-packages Maybe you like it. What does it do? installs shell shortcut ( $ pharo ) and application menu item (Gnome, KDE etc), which when called, copy Launcher image and resources into hidden user dir ( /home/USER/.pharolauncher ), if needed, and start Pharo Launcher. Packaged as DEB and RPM for i386 and x86_64. Please always verify binary integrity. M

Hi Sven, Me too I used to track a lot of interesting blogs out there.

Re: [Pharo-users] OS X bundle, some progress

On linux and MacOS the three stdio streams exist for every process: stdin, stdout & stderr. If you're starting a process from the shell, they are normally attached to the terminal (unless you redirect them). I don't know what happens on MacOS when you start a process from the GUI. > Obviously there is situation with problem creating stdout files. There's lots of MacOS users here who aren't having this problem, so my first guess is that there's something about your environment that is causing the issue.
