Assembler is pretty dumb thing. Each instruction doing something , so if you put them in right order, there's little space for faults.

(of course, not necessary to use chars, you can use ints, so it will be only 64 dummies instead of 256 ;) And of course a better way of doing that is to create a special NBExternalType subclass , lets say NBExternalTypeArray which takes a basic type and number of elements. And it should answer correct #instanceSize and other related things, as well as implement methods for pushing/storing and reading the values of such type. I will work on adding that in closest days.

HowTo not show a Debugger when calling deprecated methods in 1.4?

by Helene Bilbo

In #14459 i set *Deprecation showWarning:*, and *Deprecation raiseWarning:* both to false, but nevertheless a Debugger pops up, whenever i call a deprecated method. Is this intended or a bug? Is there another way to turn this behavior off? -- View this message in context: http://forum.world.st/HowTo-not-show-a-Debugger-when-calling-deprecated-met… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

NativeBoost external structure with char[] rather than char*

by Guy Hylton

I am looking for some NativeBoost advice on the best way of using a structure with an containing a char array like the following: int level int number char[256] msgText ulong elapsedTime Currently I am using an NBExternalAddress returned by NativeBoost>>allocate: because the external library holds onto the address and using byteAt: to see what is going on in the structure while I get used to the external library API. I can think of a couple of options, create my own NBExternalType subclass which I can use in an NBExternalStructure or subclass NBExternalAddress/Object with methods to extract the appropriate data, or have I missed the simple solution? Thanks, Guy

Sound in 1.4 or 2.0?

by Bernat Romagosa

Hi list, Is it possible to get sound working in either 1.4 or 2.0? In 2.0 almost all sound-related classes seem to have disappeared from the library, in 1.4 they haven't, but even copying the Scratch alsa (or OSS) plugin and running the image with the correct plugin parameters doesn't work for me. I asked this question before, but got no answer. Anybody else interested in working with sound in Pharo? Thanks! Bernat. p.s. I'm using Debian. -- Bernat Romagosa.

[ANN] Aida 6.5 Summer released: more Mobile, more Cloud, more REST, ...

by Janko MivÅ¡ek

Dear Smalltalkers, Summer Edition of Aida/Web framework and application server (http://www.aidaweb.si) is here with bunch of new features: *Mobile* - the separate MobileApp classes now allow the mobile version of your existing web apps to be developed and completely tailored to mobile devices. Separate AidaMobile add-on based on jQuery Mobile allows developing of professional and nice looking mobile apps, rivaling the native ones. TwitterMobileApp demo is included. *Cloud* based on Cloudfork. Thanks to financial support by Citilab Barcelona we have now an OpenID authentication and OAuth authorization support in Aida. You can see OpenID in action live on our GSoC site http://gsoc12.esug.org where you can register and one-click login using Google as OpenID provider. No username/password needed. Future planes includes Aida as OpenID provider and OAuth authorization server too. *REST* - Aida is RESTfull from the start but serving other than HTML like JSON is now easier than ever. Goal for Aida is to seamlessly extend the existing web apps to become REST API providers as well. *MethodLibrary* for importing ever more complex libraries directly from internet and together with directory hierarchy into Smalltalk methods and manage them with Smalltalk version control systems. jQuery, Twitter Bootstrap, Amber included. You can now open Amber simply as: http://localhost:8888/amber/index.html More in Release notes: http://www.aidaweb.si/release-notes-6.5 On Pharo it is really simple to load, just evaluate this script: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfAida'; load. (Smalltalk at: #ConfigurationOfAida) load. Then simply open http://www.aidaweb.si:8888 . There is also a OneClick image to get to Aida even faster: http://www.aidaweb.si/download .

I'm assuming from what I've read that it is possible, but got some issues such as BlockContext missing, references to OmniBrowser, something about loading Metacello and when it finished there were 39 failures/errors in the tests. This was just from loading from the configuration browser in a fresh 2.0 image. Is there a better way? I like the look of the new system browser so far but it has felt a little sluggish in places. I hope this improves as I almost don't want to go back to OmniBrowser now :-) > :) > > Chris > > Do not start with 2.0 because we are shaking the system :) > Now imagine that you really want, then start from the seaside configurationOfSeaside and let us know the problem you find. I'm quite happy with1.4 currently but would like to try things such as Fuel, Tanker, Nautilus and so on. With regards to Seaside, it's actually pretty close to be fair. I had to prefix MetacelloMCProject with Smalltalk at: in ConfigurationOfMetacello>>#project. The OmniBrowser packages obviously complained but I just proceeded. There are methods such as fixCallbackTemps on BlockContext and that class is now gone, presumably these could move to ContextPart? Of the failing tests after that, most were just a case of renaming calls to includesSubString: with includesSubstring: . Most of the other errors were related to SystemChangeNotifier no longer existing, the odd one where FileDirectory doesn't and so on > > >
