[Pharo-project] [NB] Speaking about callbacks
by Igor Stasenko Sept. 17, 2012

Sept. 17, 2012

Hello, there i am happy to say that during last week, i found a cure for my callback code, and so finally callbacks are now working without crashing the VM. :) But before releasing it to public, first, i need to update VMs for that, because of additional callback support code in VM. Right now, i'd like to discuss about different ways of defining/creating callbacks. And i need more input from people, because i think the way how i implemented it is good for get started, but it looks like there could be more convenient forms :) So, the existing implementation, for creating a callback, you must make a subclass of NBFFICallback, overide #fnSpec method and then instantiate it by using: callback := MyCallBack on: [:... some block ] and then you must pass it somewhere (to some external function), and so, when callback get called, your block will handle it. In objective-C, however it would be much nicer to have a smalltalk objects act as a Obj-C objects (so implementing a methods for it will naturally map them as a callbacks ). For instance imagine that i wanna make own subclass of NSFoo obj-C class and wanna override the #bar method. And then i passing it as an obj-c instance around and each time ,Obj-C #bar message is sent to it , i got a #bar message sent to my smalltalk instance. That would be really cool, isnt? Despite it is only applicable to obj-c because of similar object model :) I imagine it could be done as following: in #bar method you putting a special pragma: MyClass>>bar <objCMethod: 'int ()'> ^ 5 that's it, you telling the compiler that given method can be called from Objective-C.. and you don't have to manually instantiate callbacks etc.. In fact, same form can be used for non-objC callbacks , you must just tell something like: callback := (MyClass>>#bar) asCallbackFor: myObject. here, you instantiating a callback, which when called, the object 'myObject' will receive #bar message. But unlike from Obj-C this callback won't work for all instances of MyClass, but just for specific one. And third form is a variation of original one, instead of subclassing the NBFFICallback, actually i can change implementation to use special factory class(es) for it, so to create a callback you will do something like: callbackFactory := NBFFICallback withSignature: #( int (int x, void * bar)). callback := callbackFactory on: [:x :bar | .... ]. So, i'd like to hear your input, which one you like, and which ones you prefer to have 1. requires creating a subclass of NBFFICallback, overriding it's fnSpec method. Takes a block closure as a callback. 2. first you must create a factory object by specifying a callback signature, then you can instantiate new callbacks by passing a block closure to that factory 3. to create a callback you must specify it's signature in one of the compiled methods, and specify an object which will receive a message when callback will be called. -- Best regards, Igor Stasenko.

Re: [Pharo-project] Sending email with Pharo

Hi Hilaire, There was a post from Scott Sproule on using Amazon SES with zinc and stunnel. Sven, you remember? From the response it was not clear to me if he managed to get everything working, and the need for stunnel might not be there with the current SSL support. SES is about 10% of the cost of postmaster. Attaching to mail is a well-known process. There are no problems there. Stephan

[Pharo-project] Changing permanently the mouse cursor
by Hilaire Fernandes Sept. 17, 2012

Sept. 17, 2012

Hello, One can change temporary the mouse cursor with something like: World currentHand showTemporaryCursor: ThemeIcons eyedropperIcon But depending on the widgets the mouse is over, its cursor may change again. Beside hacking the HandMorph class is there a way to change permanently the mouse cursor? Thanks Hilaire

[Pharo-project] how to start a cog vm on debian 6.0.4
by Tudor Girba Sept. 15, 2012

Sept. 15, 2012

Hi, I would need to start a Pharo/Pier image on Debian 6.0.4 from the command line using Cog. I tried to use both the Cog-VM (from Pharo) and the Cog (from Eliot), but none work: - If I run the Cog from Eliot returns "can't infer base LD_LIBRARY_PATH. Aborting." - I could not even get the Pharo Cog to run. Even if the rights for the VM are correct, it still says: "-bash: ./CogVM: No such file or directory" Any hints as to how to proceed? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"
