NativeBoost: Regenerate Native Code
by Sean P. DeNigris Nov. 28, 2013

Nov. 28, 2013

How do I tell NativeBoost to regenerate all naive code for a class e.g. after changing the implementation of #nbCallingConvention? N.B. to NativeBoost newbies like myself, this is a *huge* potential pitfall that's difficult to diagnose. I was thinking, "well, I changed the calling convention and the vm is still crashing, so that can't be the problem" not realizing that the callouts never picked up the change ----- Cheers, Sean -- View this message in context: http://forum.world.st/NativeBoost-Regenerate-Native-Code-tp4725651.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Is there a template engine in Pharo
by Damien Cassou Nov. 28, 2013

Nov. 28, 2013

Hi, I'm looking for a template engine for Pharo. What I mean by that is the same as String>>format: but much more powerful. Thanks -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." Winston Churchill

may I be added to PharoExtras?
by Paul DeBruicker Nov. 27, 2013

Nov. 27, 2013

Hi - I'd like to get XMLParser working in Pharo 1.4. The recent updates broke it because FileSystem class>>#workingDirectory does not exist. I also have another ConfigurationOfJSON and I think Postmark to upload. Thanks Paul

Hi That's gatekeepers way of telling you the app is not from a certified developer.

Hi, would anybody knows how to do a nested layout with reversed radial tree in Roassal? I'd like to build a grid of reversed radial trees... It works with trees, but not with the radial layout.

Google Chrome.app downloaded this file today at 2:39 from www.pharo-project.org."

NativeBoost Questions while wrapping FMOD
by Sean P. DeNigris Nov. 25, 2013

Nov. 25, 2013

I'm wrapping the FMOD cross-platform audio library. The code is MIT and lives at http://smalltalkhub.com/#!/~SeanDeNigris/FMOD ======== Problem #1: ======== I'm calling into the FMOD library with: primStoreIsPlaying: channelHandle in: isPlayingHandle <primitive: #primitiveNativeCall module: #NativeBoostPlugin> "FMOD_RESULT FMOD_Channel_IsPlaying( FMOD_CHANNEL *channel, bool *isplaying);" ^ self nbCall: #(FMOD_RESULT FMOD_Channel_IsPlaying(NBExternalAddress channel, NBExternalAddress isPlayingHandle)). I call the above with: isPlaying | isPlaying | isPlaying := NBExternalAddress new. self primStoreIsPlaying: channel in: isPlaying. ^ isPlaying value > 0. isPlaying is always 0. The method works directly from C with: int isPlaying = 1; while (isPlaying) { FMOD_Channel_IsPlaying(channel, &isPlaying); } I also tried changing the callout signature to "... bool* isPlayingHandle)" and passing "isPlaying := true." instead of using the NBExternalAddress stuff. I have a few more questions, but this is the most pressing as it's holding up any further development. Thanks! ----- Cheers, Sean -- View this message in context: http://forum.world.st/NativeBoost-Questions-while-wrapping-FMOD-tp4724116.h… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

MCRepository can notify by email, did you know?
by Martin Dias Nov. 25, 2013

Nov. 25, 2013

Hi, I just discovered this feature and wanted to share it: When a version is saved, the file repositories check if a file named 'notify' exists in the repository directory [1]. If it exists, then it reads email addresses from that file and send emails notifying the new version [2]. We noticed with Camillo that this seems to be the only usage of SMTPClient in the image. I wonder if somebody is using this feature. Best regards, MartÃn ps: I'm talking of Pharo 3. [1] MCFileBasedRepository>>notifyList [2] MCVersionNotification>>notify:

PharoLauncher howto (was: SimplePersistence ...)
by Torsten Bergmann Nov. 25, 2013

Nov. 25, 2013

Norbert wrote: >How do you use it? Iâve just downloaded but failed to see how I can work with it. Warning: ======= Note that PharoLauncher is a project still in progress - I think Damien can tell you more about all the nice stuff. I just contributed some code and use it daily now. But lets continue with a short HOWTO (from my personal experience): -------------------------------------------------------------------------------------------------- PharoLauncher HOWTO: ==================== Before ====== I'm typically on Windows - in the past I had several folders with images everywhere on my HD. Sometimes with the VM, sometimes without. Lots of image searching as you can imagine. How I installed it: =================== So I downloaded a VM from http://files.pharo.org/vm/pharo/ and the latest ZIP with image and changes from https://ci.inria.fr/pharo-contribution/job/PharoLauncher/ I also put the source file into the same directory which I copied from the regular Pharo distro. All lives in one directory. I also use Linux boxes, for Ubuntu follow: http://www.pharo-project.org/pharo-download/ubuntu to get the launcher. Note that this currently will install an old image, so you have to load newer packages afterwards in the image or exchange the image. Installation will surely be simplified in the future. How I use it ============ Just launch the Pharo launcher image using the platform specific VM. Usually for "end user experience" the launcher opens in full world mode - so you see no Pharo background/world menu - only the launcher. Initially on a new computer the left side with local images is empty. On the right side are the images that are available on the web. Note that there are refresh buttons at the top of the list. Click "Refresh" in the right list to fetch all available images from the web. Select the image you like and download it. For instance you can download "Pharo3.0" -> "30587" which is the latest image as of today. Note that also the images from contribution CI are available. So you can easily download "Artefact", "Moose", ... images if you like. It will download the image into a specific directory somewhere in your users home directory. Each image gets an own folder. Use the "Show in folder" menu item if you want to open this location (may not yet work on all platforms) After download you can either "Launch" the image from the context menu in the right list. This will open the new image and close the launcher image. So you are ready to start working. What I do typically do is to "Copy" the image BEFORE I do any work and name it differently like "30587-MyStuff". Then I Launch the new copy and work with it, later throw it away or try that loading after commits works within new fresh images, ... Now === My HD is now much cleaner - all images are in a central place and I need only one icon/starter on the desk to open. PharoLauncher is also a very handy tool to download specific image update versions if you want to reproduce or fix Pharo bugs. I also associated one of the unused laptop keys with PharoLauncher - so the world of Smalltalk is just one click away... Things to know: =============== At the bottom there is a button to open a settings browser with specific settings for PharoLauncher. There is an option that enables the IDE again - so you can inspect the code or fix a bug. If it does not launch on your box then set a break in PhLImage>>launch to debug. Also note that it does not fit with the "Save as" image style - since each launcher image has to be in a new directory so far. So either use the "Copy" image, then "Launch" and then only "Save" in the target image or copy the "Saved as" image in a new folder and refresh the Launcher view on the right side. When you develop for it ======================= Either use the latest image from CI and enable the IDE as written before. You can also download the latest also in a Pharo 3.0 image. Just use the ConfigurationOfPharoLauncher from http://smalltalkhub.com/#!/~Pharo/PharoLauncher Then evaluate "PharoLauncher open". Currently it was rewritten using Spec for the UI, also all the actions are rewritten using Command Pattern so you can extend the buttons, menues if you like. Hope this helps a little bit Bye T.
