Andreas 14-Jul-2010 [17541] | Brian, you don't have to. |
Ladislav 14-Jul-2010 [17542] | (unsupported) |
Andreas 14-Jul-2010 [17543] | Report the observed difference and the expectation that this should not differ. The rest is up to whoever feels qualified to contribute more detailed observations and/or implementing a fix. |
BrianH 14-Jul-2010 [17544x2] | Andreas, sorry, CureCode doesn't let you report a platform-specific bug without specifying the platform. I can't just say "it's not consistent" without it being a useless bug report. We need a report from a person who is qualified to make an expert decision. |
At the very least, it means that any report I make would have to be rewritten (or comments to the same effect) by Ladislav, or someone equivalently qualified. | |
Ladislav 14-Jul-2010 [17546] | I can admit it is a bug, by I cannot really correct it in MS C without "too much expense" |
Andreas 14-Jul-2010 [17547x2] | http://www.curecode.org/rebol3/ticket.rsp?id=1633 |
See, that was not so hard to report, was it? | |
BrianH 14-Jul-2010 [17549] | Just like I have to rewrite all of the bug reports about R3's module system before they can be useful. It sucks, but we need an expert. |
Andreas 14-Jul-2010 [17550] | Now it is in the system, on those more knowledgeable on the matter can refine it. |
BrianH 14-Jul-2010 [17551x2] | Ladislav? |
What do you mean by "too much expense"? | |
Ladislav 14-Jul-2010 [17553] | Well, sure, it is a report, but, as I said, I am not going to correct it (would be too expensive) |
Andreas 14-Jul-2010 [17554] | That's not a problem. If it is not possible to fix, Carl or someone else can decide that this behaviour is ok and mark it as won't fix. |
Ladislav 14-Jul-2010 [17555x2] | To implement my own formatter, MS disallows me to use the best datatype for it |
So, I have to use their formatting function, which produces this result | |
BrianH 14-Jul-2010 [17557] | Please put that in a comment of bug#1633 - it might help justify not using MS's compiler. |
Steeve 14-Jul-2010 [17558x2] | Ladislav, I would like to see how you write that formatter under GCC, Is that too much code that you can't show it us ? |
If so, forget it | |
Ladislav 14-Jul-2010 [17560x3] | Hmm, I should not do it, I suppose. |
But, the principle is quite simple: multiply the number by a "suitable" power of 10 and convert the result to integer. The trouble is, that you need to use a high precision multiplication and power. | |
(which is unsupported in MS compiler) | |
Steeve 14-Jul-2010 [17563] | You mean, you don't do it using an incremental way, each digit separatly ? |
Ladislav 14-Jul-2010 [17564] | No |
BrianH 14-Jul-2010 [17565] | What version of the MS compiler is being used? Can it be upgraded, and would that help? Can the Intel compiler be used, or the DMC++? |
Ladislav 14-Jul-2010 [17566] | Only "ancient" versions of MS compiler support the extended precision |
Andreas 14-Jul-2010 [17567] | GCC should suffice. And as Carl is already using it for the Host Kit, it may also be possible. |
Gabriele 15-Jul-2010 [17568x4] | Max: this is very funny. normal MOLD, afaik, is only there for backward compatibilty. i personally almost always use /all, when i don't use it it's because i'm molding something i just loaded or something like that, eg. i know that i don't need the /all, bet even if i used it it would make no difference at all. |
it's very very hard imho to come up with reason NOT to use /all... | |
if you try to DO a script saved with SAVE/all or MOLD/all, it will fail if it contains functions or objects. - show me an example. | |
The primary purpose of SAVE is to save scripts that are to later be processed by DO. - weird, i always use save and load to save and load data. but, even if that was the case, save/all would work just as well, so this is a silly argument. | |
Graham 15-Jul-2010 [17572] | Hmm... I recall saving rebol objects with save/all and not being able to load them again properly |
Gabriele 15-Jul-2010 [17573] | but SAVE is not only for DED, THAT is my point. - in that case, SAVE/ALL is *BETTER* than SAVE. there is no argument about that. |
Graham 15-Jul-2010 [17574] | some problem with functions inside objects or something |
Gabriele 15-Jul-2010 [17575x5] | If you write them out directly in that syntax, you are mixing paradigms. - that makes NO sense. I write them directly MANY times because it saves useless evaluation of DATA |
Brian: your #[function! ] example is something I have ALWAYS pointed out as a bug and you ALWAYS countered by saying it is a "security feature" which i still thing is a very stupid thing to do (doing that as a "security feature") | |
SAVE and MOLD are explicitly designed to be newbie-friendly - I though Carl had realized, that "newbie-friendly" is the worst thing you can do to a language. I hope others realize this as well, as soon as possible... | |
Graham: show me ONE example of something you can LOAD but then breaks when you SAVE/ALL it back. | |
SAVE is *not* able to serialize arbitrary REBOL data. that is a known problem that Carl did not consider important enough to address, since he prefers using dialects to interchange data instead of just moving around the internal representation a program may be using. | |
Ladislav 15-Jul-2010 [17580x2] | User friendliness is in the eye of the beholder. I consider this: >> block: [none #[none] true #[true] 0.1 0.10000000000000002] >> print mold/all block [none #[none] true #[true] 0.10000000000000001 0.10000000000000002] >> print mold block [none none true true 0.1 0.1] as a problem for me, trying to give me wrong informations, as well a a problem for a beginner, who may not even be able to find out the informations he obtained were wrong |
CureCode #1634, add a "me too", if you like | |
Maxim 15-Jul-2010 [17582] | Gabriele, I also always use /ALL, when molding. as I stated, I was playing devil's advocate, in which case I helped improve the case for SAVE/ALL being better. but I'm not sure its a good thing to break the symmetry between mold/all and save/all. IMHO if we change one, we should change both. IMO this is a better solution. but this doens't change the fact that MOLDing is severely limited in many ways. |
BrianH 15-Jul-2010 [17583x3] | Gabriele, that "security feature" argument was always more of a "look on the bright side" thing, not really countering the argument that it may be a bug. However, more functions are usable in R3 after being built with #function! ...] than were with R2 - apparently references to the "global" environment are bound, and then the function-local environment. I have yet to figure out how, but I'm working on it; a clue is that there is no real "global" environment. That means you lose the security benefits of the non-feature in R3, so enjoy the get-path and SELECT security enhancements that more than compensate for such things. |
Ladislav, you, Gabriele and I are not the kind of users that MOLD is trying to be friendly to. Try newbies. | |
Apparently the particular "global" context bound to serialized functions in R3 is the system context, not the user context. Or maybe it's the exports context - hard to distinguish them right now, since system and exports is currently the same object (it's a work in process). So that makes serialized functions minimally useful in R3, instead of not useful at all as in R2. Interesting. | |
Ladislav 15-Jul-2010 [17586x2] | Try newbies : unless I find out you are right, I do not have any reason to believe you (I remember, that I was a newbie once too) |
The trouble is, that the situation is worse, as far as I am concerned. To me, MOLD is quite "hostile" actually | |
BrianH 15-Jul-2010 [17588] | You are the type of programmer who will look up the IEEE754 standard to determine math behavior, or will write in C if necessary. You are not MOLD's target market :) |
Ladislav 15-Jul-2010 [17589x2] | Wrong, I *am* MOLD's target market currently, without having any other choice: console forces me to read that nonsense |
That is why I wrote #1634 | |
