[Pharo-project] Logging into squeaksource(3)
by Sean P. DeNigris April 26, 2012

April 26, 2012

This snippet is very useful, but it would have to be reapplied when new repos are added: repos := (MCWorkingCopy allManagers gather: [:e | e repositoryGroup repositories]) asSet. squeaksourceRepos := repos select: [:each | (each isKindOf: MCHttpRepository) and: [ each locationWithTrailingSlash beginsWith: 'http://www.squeaksource.com'] ]. squeaksourceRepos do: [:each | each user: 'user'; password: 'password']. I'm imagining an in-image mechanism to provide credentials to various online repos and then new http repos should automatically be fed those credentials. anObject forReposAt: 'http://www.squeaksource.com' loginAs: 'user' withPassword: 'password'. And then automatically add this info to new repos at that host.

[Pharo-project] [ANN] Styled Text Editor for Cuis 4.0 Smalltalk
by Bernhard Pieber April 26, 2012

April 26, 2012

Dear Smalltalkers, I am very happy to announce that the Styled Text Editor for the brand new Cuis 4.0 is now available on GitHub [1]. The Styled Text Editor was first presented by me at last year's ESUG in Edinburgh [2]. Thanks to ESUG the presentation was recorded [3]. The Styled Text Editor is a framework for rich text editing using styles as known from popular word processors like Apple Pages or Microsoft Word. It features paragraph and character styles, allowing easy text formatting using styles only. It is intended for applications where users need to work with good looking rich text in a simple and fast way. Rich text commonly refers to text with formatting information like different fonts, sizes, alignments, and emphasis. To make editing as simple as possible instead of individual formatting information end users apply styles to parts of the text. Editing is made fast by keyboard shortcuts for text navigation, selection, and styles selection. Where possible the feel of widely used rich text editors is supported. It includes many features like - numbered and bulleted list paragraph styles - support for images - multiple level undo and redo - text completion using various glossaries including a dictionary of English with about 166.000 words - RTF clipboard (on OS X VMs with the ClipboardExtendedPlugin) The Styled Text Editor is developed in Cuis with the plan to eventually port it to Squeak and Pharo. The development of the Styled Text Editor inspired many changes to Cuis itself, and It is the first package to use the brand new DVCS based development process for external packages for Cuis 4.0. The idea and funding was provided by me, Bernhard Pieber and my company Software Generation. The implementation was done by Juan Vuletich, the mastermind behind Cuis. Thanks Juan for the close cooperation. It was and still is great fun to work with you. We are looking forward to feedback from you. Fork it on GitHub [1], create issues and send us pull requests. ;-) Cheers, Bernhard Pieber [1] https://github.com/bpieber/Cuis-StyledTextEditor [2] http://www.esug.org/wiki/pier/Conferences/2011/Schedule-And-Talks/StyledTex… [3] http://www.youtube.com/watch?v=pUoVbvwspi8&list=PL813665D04A2E4C0A&index=7&…

[Pharo-project] Editor focus & hotkeys
by blake April 26, 2012

April 26, 2012

So, I'm entering code into a browser (Nautilus browser, though I don't think this behavior is specific to Nautilus), press Ctrl+S to save and... ...the code editor loses focus. Looks like it goes to the method pane, which seems reasonable. But now, to enter my next method, I have to take my hands off the keyboard and click the mouse. Nautilus seems insensate to the Tab key...how do I get from the method pane back to the code editor sans mouse? ===Blake===

Re: [Pharo-project] OSProcess - is process done?
by DeNigris Sean April 26, 2012

April 26, 2012

> Hi Sean, > > An fread() call will block when reading from a unix pipe unless the pipe > end has been set to nonblocking mode (see #primSQFileSetNonBlocking:). So the #upToEnd problem was solved by sending #setNonBlockingOutput. So the following simple in-image ssh client works: p := PipeableOSProcess command: '/usr/bin/expect /path/to/expect_file.exp ', password, ' ', ipAddress. p setNonBlockingOutput. "This was added. Otherwise, #upToEnd hangs the image" p nextPutAll: 'ls', Character cr asString. p upToEnd. p nextPutAll: 'pwd', Character cr asString. p upToEnd. The reason that I didn't think to do this before is that I thought the whole point of #upToEnd was that it was *inherently* non-blocking... > - Open a test runner and run CommandShellTestCase... Yes, they all passed except the PipeableOSProcessTestCase ones... The other problem ("p := PipeableOSProcess waitForCommand: 'ps -ax -o pid,command'" hangs forever) is not happening right now. It's returning as soon as the process is finished, so I'll have to get back to you if it pops up again... Thanks for all the help! And is a fix required for #upToEnd based on the above? Sean

[Pharo-project] Confused about #isDirectory
by Sven Van Caekenberghe April 26, 2012

April 26, 2012

Hi, I don't understand why '/tmp' asReference isDirectory. false '/private/tmp' asReference isDirectory. false '/Users/sven' asReference isDirectory. true '/Users/sven/Desktop' asReference isDirectory. true on Pharo 1.4 Mac OS X Cog VM. Anybody any idea ? Am I doing something wrong ? Thx, Sven

[Pharo-project] How to declare Zinc/FS dependency in Metacello Configuration for 1.4
by Francois Stephany April 26, 2012

April 26, 2012

I'm updating some Metacello configurations and I'm wondering how to declare the dependencies on stuff that have been integrated into Pharo 1.4 (e.g., Zinc, FS). Should I declare those dependencies into my configuration? If yes, against with version? My gut feeling is that I should create a new baseline that does not require any Zinc of FS. That becomes a pain in the ass when developing in parallel for 1.3 and 1.4. Is the only place where I can differentiate 1.3 and 1.4 is in the stable symbolic version, right? What are people generally doing? Cheers, Francois

[Pharo-project] JSON, Smalltalk parser and no-point wars
by Miguel CobÃ¡ April 26, 2012

April 26, 2012

Friends, what energy! But I don't know why are we discussing this point of JSON choice so long. It is an implementation detail. If he choose to use XML, so be. It is Dale's time and Dale's code. Remember his projects is not to build a inter-dialect metadata format. His project is all about building an inter-dialect package format to store smalltalk. And in that goal he is succeeding! Lets no make a flame war about his choices. What is matters now is to show to as many smalltalk dialects as possible, that code interchange is possible. That is the fucking point. If after that, because the implementation is slow, or some other real after-use problem is detected, then is the time to discuss how to better address that specific problem. Until then, this is a bikeshedding like inane problem. Remember make it work, make it right, make it fast! Dale is in make it work. Every other not putting code on the project is trying to make it right (intelectually and upfront). Lets not stop the work of others by discussing the best way to do it instead of doing it. Some famous people around here made an analogy about a mountain and the people trying to climb it. Don't forget that! Cheer to all. -- Miguel CobÃ¡ http://twitter.com/MiguelCobaMtz http://miguel.leugim.com.mx
