Adding method slots dynamically
by oscar_lopez_p 16 Aug '05

Hello, How can I add dynamically a method slot to a self object? . I have: the method selector, the argument names and the body (source code) of a method, and I need (at runtime) to create a method from them and add it to an existing object. Thanks for the help, Oscar Lopez

Performance?
by Michael Latta 19 Oct '04

The Squeak list has postings for bytecodes/sec and sends/sec. Are similar figures avaialble for self? Is there a benchmark that can be run to get similar figures? I would be interested in knowing the relative performance of the two systems. Squeak seems to be running > 1000 cycles / bytecode. This seems quite high compared to the techniques used in the Self compiler, even with GC and compiler overhead. Michael

on the power of self-recursion
by joglimming 17 Oct '04

Dear Self-enthusiasts, I am looking for examples of algorithms or recurring software patterns which are self-mutable, or which are greatly simplified/made more efficient because of method update. Is anyone aware of some strikingly nice bits of Self code that illuminates the power of method update in capturing recurring reusable patterns or in algorithm design? For example, are there some algorithms which are particularly nice/simple/efficient/ reusable in Self? By the way, I am working on a recursion principle within object-based programming languages. This principle allows recursive method updates to be performed. I am trying to develop an algebra of object-oriented programs for pointfree derivations of programs. Best Wishes, Johan Glimming
