Keyboard issue with Self on Ubuntu 9.10
by cosinusoidaly 28 Feb '10

28 Feb '10

Hi I'm having a weird keyboard issue with Self on Ubuntu 9.10. The gui is behaving as if I am continually holding down ctrl (so v pastes, x cuts and so on). This affects Self 4.4 Alpha 2 and the latest git. Any ideas what's going on? This doesn't seem to affect 9.04.

Self or Slate; Differences?
by Tim 24 Feb '10

24 Feb '10

I am looking to learn a new language. After researching Smalltalk a bit, I have decided I would prefer to learn a prototype based langusge. I have narrowed my choices to Self and Slate. Can anyone explain the differences to me? I know Slate uses a syntax very close to Smalltalk. What else? Thanks in advance. Teejay

Hi All, Is there any spec of the self VM? I mean a description of the instructions etc? -- View this message in context: http://n2.nabble.com/Self-VM-tp4561785p4561785.html Sent from the Self mailing list archive at Nabble.com.

Disassembling methods
by Chris Double 10 Feb '10

10 Feb '10

Is it possible to see the bytecode that makes up a method of an object? If so, how? How can I get a reference to an actual method object? In trying to find this out I see some interesting objects like 'methodDisassembler' and other objects that have 'abstractBytecodeInterpreter' as parents (localAccessFinder for example). How can these be used? I couldn't find any references of usage anywhere. Chris. -- http://bluishcoder.co.nz

Compiling SELF on windows
by smisra 09 Feb '10

09 Feb '10

Hi All, Not sure if any one asked this earlier, is there a SELF port of MS windows? If not I am willing to work on the windows port, but I will need some help on the source tree for self. If any one has started the effort then please let me know. -- View this message in context: http://n2.nabble.com/Compiling-SELF-on-windows-tp4532551p4532551.html Sent from the Self mailing list archive at Nabble.com.

Some question regarding SELF VM
by smisra 09 Feb '10

09 Feb '10

This may be a premature question. I should read all the papers on SELF before writing this, but I am just too curious. Why do we have a different SELF VM. >From the few documents I read, I found that self helped improve the VM technology for java vm. Then why not use java VM? Or LLVM? I am just asking this because of the experience I had with the scratch VM recently. Well it's a smalltalk variant squeak, its a great system, but I was not able to use it in a simple game I created. The fact is the smalltalk makes it not so easy to integrate it with some other C++/JAVA system, and the maintainers of the language suggested me to learn smalltalk, which I am not so curious to do. Having a common VM platform may enable different users to use SELF objects from other programing language also. I am sure there is a solid reason for having a separate VM for self. ~Thanks -- View this message in context: http://n2.nabble.com/Some-question-regarding-SELF-VM-tp4532662p4532662.html Sent from the Self mailing list archive at Nabble.com.

Some questions about Self (Transcript, Modules, Browsing Subobjects, Debugging, defaultBehavior)
by shanenbe 02 Feb '10

02 Feb '10

Hi all, I am relatively new in Self and have a bunch of questions (I am using Self 4.4 alpha2/Linux). 1. Transcript I wanted to implement something such as Transcript - but I saw that there is already such an object (but I cannot open it). transcript copy show. ends with a "depth not found"-error. Is it maybe a restriction of my linux, or does transcript really has this problem? 2. Modules Is there an easy way to see what elements are in a module? For examples, I added a module "shChanges" which I open via "modules shChanges". Can I see somehow what objects exist in this module? 3. Subobjects of a certain object Is there a way to see what objects are subobjects of a given one? For example, if I have an outliner for "defaultBehavior". Is there a way to get a list of all object which use defaultBehavior as parent? 4. Debugging Is there a way to evaluate an object which is shown in the debugger. For example, if I have a error in a statement such as doPrint: myObject doSomething and I want to inspect myObject. Does the debugger provide such a thing? Can I evaluate a statement using the context of the debugger? 5. Design decision with defaultBehavior I am slightly confused about the design decision that not every object has defaultBehavior as super object. Is this intended in that way or rather "an accident"? The reason why it confuses me is, that i cannot use a new created object within a collection (since slots for e.g. comparing objects are not available). -Stefan

Building on Linux
by Chris Double 02 Feb '10

02 Feb '10

Builds from the git repository are broken on Linux due to some recent changes to get things working on Snow Leopard. I've attached a patch to the ticket for the issue which gets builds working again: <http://self.lighthouseapp.com/projects/42988/tickets/2-self-wont-compile-on…> Chris. -- http://bluishcoder.co.nz
