Pekr 9-Apr-2013 [2310] | no way=no need ... |
Robert 9-Apr-2013 [2311x2] | I don't take it that way. |
I'm just wondering why things don't lift up... and the explanation given. I'm just wondering. | |
Pekr 9-Apr-2013 [2313] | Well, just count ppl here ... how many ppl are active? Even this channel is now split between here and Stack Overflow ... |
Robert 9-Apr-2013 [2314x2] | From my experience one of the golden rules of life is (wow that gets philosophical): Waiting doesn't change thigns, you need to do it. |
Sure, but if this is the conclusion, we better stop today and use something different. | |
Pekr 9-Apr-2013 [2316] | Yes, I know - if I would have to write some small util for me, it surely would be R3 nowadays. The only thing I might miss is better CALL and maybe ftp protocol. But it can be solved .... |
Robert 9-Apr-2013 [2317] | And of course time is limited, tell me. Nevertheless, if it's important people will do things. |
Pekr 9-Apr-2013 [2318] | Imo MaxV is trying to do the stuff, just look into his blog. He is just comparing what he was used to, with his new experience imo |
GiuseppeC 9-Apr-2013 [2319x3] | Ladislav, my role in life is not to label what human beings are doing but change the way they look at things to overcome their obstacles. |
Excuses come from tipical rapresentation of the reality inside ones mind. | |
Could you please complete the list of changes in REBOL3 than REBOL2 ? Your is very valuable information. | |
Ladislav 9-Apr-2013 [2322x2] | Could you please complete the list of changes in REBOL3 - that is a problem: I do not think such a list can be made "complete". Some changes actually are "code cleanup", e.g. Also, there is a time problem: I would have to browse R3 Chat, CureCode, AltMe, DocBase, Carl's blog, Carl's R3 doc, GitHub, whatnot to do it. Why do you think I am the one who has got the time to do it? |
OK, to be of some help I decided to compile a couple of notes of this kind as an article for the future reference/improvement. | |
GiuseppeC 9-Apr-2013 [2324] | Thanks Ladislav ! |
Endo 9-Apr-2013 [2325] | Great! |
MaxV 9-Apr-2013 [2326] | To all people who want to dare in Documentation R3 GUI labirinth , you may use http://rebol.informe.com/wiki/view/Main_Pageto help community. |
GiuseppeC 9-Apr-2013 [2327] | I think it could be a good start. However, Ladislav usualli works on REBOL wiki. |
Gregg 9-Apr-2013 [2328x3] | I'm not waiting for anything in particular WRT R3. I am very anxious to have time to start using it more, and I am grateful to the Saphirion team for taking the lead on it and doing so much work. Because they have, I decided that what time I can make right now I will put behind Red, as I think I can provide more value there, and to give Doc some support for all his work too. |
I'm also going to post more thoughts and questions about funcs, like I did with SPLIT-PATH, because now is the time to make any changes, IMO. | |
Ren is a new distraction now too. :-) But I think it will be good for all of us. | |
MaxV 11-Apr-2013 [2331] | Please, may you add some examples in the following pages? http://rebol.informe.com/wiki/view/Rebol_3-set-face http://rebol.informe.com/wiki/view/Rebol_3-get-face |
Ladislav 13-Apr-2013 [2332x4] | How do you like this "Implementation artefact": f: make function! reduce [[x /local x-v y-v] body: [ x-v: either error? try [get/any 'x] [ "x does not have a value!" ] [ rejoin ["x: " mold/all :x] ] y-v: either error? try [get/any 'y] [ "y does not have a value" ] [ rejoin ["y: " mold/all :y] ] print [x-v y-v] ]] g: make function! reduce [[y /local x-v y-v] body] >> f 1 x: 1 y: 1 |
(specailly Andreas should have a look) | |
Just for comparison, these results are from R2: f: make function! [x /local x-v y-v] body: [ x-v: either error? try [get 'x] [ "x does not have a value" ] [ rejoin ["x: " mold/all :x] ] y-v: either error? try [get 'y] [ "y does not have a value" ] [ rejoin ["y: " mold/all :y] ] print [x-v y-v] unless value? 'y [g 2] ] g: make function! [y /local x-v y-v] body >> f 1 x: 1 y does not have a value x does not have a value y: 2 | |

Andreas 13-Apr-2013 [2336] | Very good catch, Ladislav. A rather nasty bug. |
Ladislav 13-Apr-2013 [2337] | (remedy is not hard, already found out how to correct it) |
Andreas 13-Apr-2013 [2338] | Point the "frame" to the full function value instead of just the function's body. |
Ladislav 13-Apr-2013 [2339x2] | - not exactly |
(that would be quite incomfortable) | |
Andreas 13-Apr-2013 [2341] | Interested in any alternative fixes, but I see no discomfort for the above. |
Ladislav 13-Apr-2013 [2342x2] | Well, there is some discomfort. REB_FUNCTION values are not garbage collected. |
However, fortunately, the ARGS series is unique to function (since it is created specifically for the function), so it can be used instead of the body. | |
Andreas 13-Apr-2013 [2344] | That's indeed rather annoying. Seems the GC leaves much to be desired. |
Ladislav 13-Apr-2013 [2345] | (even if two functions have the same SPEC and BODY, they always have distinct ARGS) |
Andreas 13-Apr-2013 [2346] | Ok. That's better (even though it is a somewhat ugly hack). |
Ladislav 13-Apr-2013 [2347] | Well, but the fact that REB_FUNCTIONs don't need GC is not ugly IMO. |
Andreas 13-Apr-2013 [2348x2] | One negation too much. |
(Meaning: sorry, I'm not sure I understand what you are trying to say.) | |
Ladislav 13-Apr-2013 [2350x3] | You mean you dislike it? |
Integers, decimals, REB_FUNCTIONS, whatnot... don't need GC. | |
Only series and GOBs need GC | |
Andreas 13-Apr-2013 [2353x3] | Quite fortunate that you know already know enough of the GC to not mistakenly walk down the wrong road. |
I didn't yet check how REB_FUNCTIONs are created, but why should they _not_ be GC'd? | |
Are they pooled or managed using a custom allocator? | |
Ladislav 13-Apr-2013 [2356] | Exactly for the same reason why integers do not need GC. They are not allocated, so they don't need deallocation |
Andreas 13-Apr-2013 [2357x3] | Ah, so they can only be contained within a series. |
Ok. | |
(Or a gob, maybe.) | |
