funny idea Symbol vs. Selector
by stephane ducasse May 14, 2015

May 14, 2015

Hi guys I'm thinking aloud... I was wondering if we could not take advantage of a new class: Selector. MethodDict would only contain selectors and not symbols. I remember that I talked about that with hernan. Stef

How do I save contents of Workspace into a collection?
by Frank Church Jan. 31, 2015

Jan. 31, 2015

Hi guys, My images are gathering a number of Workspaces whose contents I don't want to delete. I want to create a collection of Workspace contents along this defintion: Description Date Category Content (the actual text in the Workspace). In the final version I would like to be able to select a workspace and simply click a button or a menu item and get a dialog where I can enter the Description, Category and Date with the Workspace contents automatically captured into a text box. Copying and pasting the contents would be okay to start with. Filing it out would be another aspect later. What kind of array would best suited to the task? There is quite a number of them depicted here: http://www.jmcsweeney.co.uk/computing/m206/collections_intro.php What could be the best way to go about it? For those who are curious I am experimenting with the original ideas of Smalltalk where a computer user would do everything in Smalltalk workspace/desktop. I am intrigued by the possibility and somehow it seems eminently doable. -- Frank Church ======================= http://devblog.brahmancreations.com

Postmark email library
by Francois Stephany Aug. 31, 2013

Aug. 31, 2013

Hi guys, I've made a simple wrapper around the Postmark API. It lets you send emails without dealing with a SMTP server. You can read about it here: http://developer.postmarkapp.com/developer-libs.html http://developer.postmarkapp.com/developer-build.html and there: http://articles.tulipemoutarde.be/send-email-from-pharo-with-postmark It's pretty simple and naive implementation but it gets the job done. I'll add email attachements when I will need it. Francois

Package browser?
by Rob Vens June 28, 2013

June 28, 2013

I am attempting to do the Pharo by Example book, but a package browser (which is used in the examples) is not in the 1.1.1 or 1.2 image. Should I still use categories? If I create a package in Monticello browser I am not able to add classes or anything (not as far as I could see). Just starting out using Pharo, so apologies if these questions are already answered elsewhere.

Re: [Pharo-users] Phaas - anyone interested in setting up Pharo as a Service?

And, I was really quite optimistic about cloud foundry when it first came out. I particularly like the way you can have a local micro cloud, and then transition to the hosted cloud. My only disappointment was that VMware are not - seemingly - going to offer gemstone as an option on cloudfoundry.com. Building on what Janko said, I think it is really important to join the cloud 'wave'. The question is how might we - collectively - make this happen? I am perfectly happy to go with cloud foundry, or open shift, or any other option if more knowledgeable people can show that X is the way to go. My only requirement is that I don't want to deal with anyone lower than pharo. All OS patches need to be done automagically by the hosting provider. I think cloudfoundry.com and open shift do that, but my understanding of cloudfoundry.org is that this is a 'roll it yourself' solution. Obviously, that would require someone to step up and do that for us. My preference would be for us to create a suitably configured module for one of e platforms, and we can then start getting experience with it. Stephane, is this something that the consortium might take a lead on? My company is happy to pay some of the costs, if this will help. Cheer Andy

Pharo 1.4 Unable to download from HTTPS Monticello repository
by Federico.Balaguer March 12, 2013

March 12, 2013

Hello I am having problems downloading packages from a HTTPS Monticello repository. The image has Zodiac installed. I am able to upload versions but I cannot download them. I am able to download the packages from a web-browser, Using the Monticello Browser I can browse the content of the given repository. When I select any package on the repository a debugger pops up: "MNU: Character>>bitOr:" I do not see how to fix the problem, at some point, MCMczReader>>zip calls Zip>>readFrom: calls Zip>>readEndOfCentralDirectoryFrom: calls ReadStream>>nextLittleEndianNumber: calls SmallInteger>>bitOr: with a Character as parameter which makes the <primitive 15> to fail. I can try to fix the problem but I would need a little help to understand the root of the problem.

Is there a keyboard shortcut to open the world menu from anywhere? How about adding a button to the taskbar?

I know the order of execution from smalltalk documentation. But what if i need this information inside an app i'm building. tutorial: aTutorialClass lesson: aSelector | tutorial | tutorial := aTutorialClass new. self player tutorial: tutorial. self tutorial: aTutorialClass lessonAt: (tutorial indexOfLesson: aSelector).

Pharo 2.0 - System Error Handling Failed
by Andy Burnett Jan. 30, 2013

Jan. 30, 2013

I am running the Pharo 2.0 beta, and I am getting a lot of System Error Handling Failed events. Is this simply a product of the beta status, or have I somehow enabled some kind of debug switch? For example, in a workspace I execute a doit on: fd := FileDialogWindow new. fn := fd openInWorld. When I click OK in the dialog box, I get the System Error screen. On other occasions I get the screen, press space to continue, then I get the debug window, and when attempting to debug it bounces me back to the System Error screen. Normal behaviour for the beta, or operator error on my part? Cheers Andy

Getting started with Gemstone for Pharo users
by Bernat Romagosa Jan. 29, 2013

Jan. 29, 2013

Hi list, I've heard the "develop in Pharo, deploy in Gemstone" idea a million times, and I'd like to understand how people proceed in real-world cases. I've done my homework and I've watched and read a lot of beginner tutorials, but I still have lots of pieces missing. Here's our scenario: We have a web app, built on Pharo 1.4 and Iliad 0.9.1.2. Currently, we handle persistence on the image and we have a scheduler process doing regular Fuel backups every 10 minutes, and we also keep daily backups in case things go wrong. The app is starting to gain momentum, and it feels like things are going to start being way too sluggish soon, so we need to scale. We've been trying many different persistence approaches, but we'd love to stay inside Smalltalk. We hate having to flatten and pump back our objects all the time. Also, REST apis to any kind of DB are not good enough for us, every o(n) operation becomes unbearably slow, as n REST calls must be sent out and n answers received. In short, we want to use Gemstone, as we've read it's best for complex, intertwined Smalltalk models, and it scales like crazy. We'd be okay with Pharo being the "dealer" between clients and the DB, but as I understand, GemTools can't be installed on Pharo 1.4, so we're kind of stuck with an old Pharo 1.1.1 image, in which Iliad 0.9.1.2 can't be installed. What's the solution here? How does one proceed to migrate an app of this kind? We've developed in Pharo, now how does one accomplish the "deploy in Gemstone" part? Any pointers to documentation, blog posts or whatever will be so much appreciated. Thanks a lot in advance, Bernat. -- Bernat Romagosa.
