Example - Vectors.Vector MyRec = RECORD i1: INTEGER; END; MyVec = RECORD (Vectors.Vector) data*: POINTER TO ARRAY OF MyRec; END; vec.Init(10); Log.String("Pointer Initial Size,Capacity="); Log.Int(vec.size); Log.Int(vec.capacity); Log.Ln; mr.i1 := 109; vec.Set(9, mr); mr.i1 := 110; vec.Set...

I'm going to introduce Scl - Standard Container Library. Scl package implements vectors, lists, queues, stacks, maps without any generics. It uses BlackBox Kernel metadata. Motivation: 1. The same software for the same tasks like sorting or binary search of elements; 2. No generics infrastructure; 3...

New Co_ version in updated in http://www.zinnamturm.eu/downloadsAC.htm#Co_
For BlackBox 1.7.1 use it as is
For BlackBox before 1.7.1 please, copy Mod/Routines6.odc Mod/Routines.obc before compilation.

certainly,coroutine must has "state" field; then user's can use "resume","yeild","sleep" Co_ is based on Carrier-Link-Rider model: Scheduler-Dispatcher-Coroutine. Scheduler holds state, the basic states are: ST_READY* = 1; ST_LOCKED* = 2; ST_FINISHED* = 3; ST...

Co_SchedTasks can be reimplemented in standart BlackBox way for your own needs.
Co.scheduler and Co.stdScheduler are factories like Files.dir, Files.stdDir.

if we can implement the coroutine use stackless tech, maybe we can make an optimization for special cases offered by some languages but it needs a language change and heavy optimizations in the compiler I've written before https://community.blackboxframework.org/viewtopic.php?f=54&t=164&sta...

Your example, please: Main creates A A creates B A transfers to B B yields to A A transfers to B B yields to A A transfers to B B yields to A A transfers to B B yields to A A transfers to B B yields to A A transfers to B B yields to A A yields to Main I just removed (*ASSERT(current = NIL, MUST_BE_P...

Ivan, The dialog is much better in this case. Otherwise (for example) center's Coroutines Sleep(0) implementation can never exceed 6% CPU. You have mentioned the problem, I've provided time comparisons. By the way, I have 2 latest builts: 849 mentioned above and 852 http://blackboxframework.org/unst...

Josef,

You are cheating, not I do. The latest build you mentioned is http://blackboxframework.org/unstable/i ... a1.849.zip. There are no nested coroutines example in ObxCoroutines there.

And what about the overlap between the 2014 Co_ subsystem and the 2017 Center proposals? Is it large overlap? Is it a good thing? Is it a bad thing? The center's Coroutines are general purpose while the Co_ package, as far as I understand it Several final cuts about two subsystems should be done fr...
