BrianH 10-Apr-2009 [13185x2] | I think. The /only changes are still being tested. Here's the pre-/only version: resolve: funco [ "Set known values in target from those given by the source." target [object! port!] source [object! port!] ][ set/any bind words-of source target get/any source also target set [source target] none ] |
It took a lot of thought to get that code so small :) | |
Pekr 10-Apr-2009 [13187] | It takes a lot of thought in order to understand the code (for me) :-) |
BrianH 10-Apr-2009 [13188x5] | Darn, /only doesn't work there. I was trying to come up with it on the fly and I failed, miserably :( |
The version without /only works perfectly. | |
It works in R3 of course. I just haven't had the time to backport the changes in the last 9 alphas (in two weeks) to R2-Forward yet.. | |
Sorry, 10 alphas in 2 weeks :) | |
Two alphas yesterday evening alone - that's my kind of release pace :) | |
Pekr 10-Apr-2009 [13193] | What do you think of system object? It looks chaotic to me. It makes no sense for me to rename, or move stuff around. |
BrianH 10-Apr-2009 [13194x2] | Oh, I love it. The old system object was chaotic. This one will be organized. We need this for memory protection and multitasking. |
R2 works now, but it has a lot of design flaws and bugs we are fixing. That's why R3 is different than R2. | |
Pekr 10-Apr-2009 [13196] | I can understand. But I liked e.g. system/components, which listed internal modules. Now we have some stuff in codecs, some stuff in contexts, View is separate, etc. |
BrianH 10-Apr-2009 [13197x2] | Think of modules as the new components, except you can write them in REBOL too. They even use the same Needs header. |
Codecs are like port schemes, but for encoding and decoding. Different thing. | |
Pekr 10-Apr-2009 [13199x3] | So why is View separate, and not in Modules section? |
... and - what is Contexts? | |
btw - Codecs were moved away from Catalog, because Codecs will change. Where's the catalog/file-types placed now? (it will not be immutable too) | |
BrianH 10-Apr-2009 [13202x3] | SYSTEM/view is View settings - we'll have View modules too, in with the rest of the modules. We just haven't modularized the code yet - we needed to have modules first. The file-types setting is in system/options with the rest of the general system options. |
As for system/contexts: Do you remember system/words ? We have more than one now. It's a module thing - separated contexts. | |
We need to have volatile settings separated from unchanging settings, becuase the unchanging stuff can be shared between tasks and the volatile stuff can't. And the hidden stuff can be tricky to access if you don't know what you're doing, so that is separate too. The new organization strategy makes sense. The only thing I miss is system/user/home, so we'll need a new place for that too - maybe system/options/user-home. | |
Pekr 10-Apr-2009 [13205] | I am thinking of a preferences system too. But that is not really a problem - user.r can be good place to place various settings. What we haven't solved or even thought about is - localisation. Messages and other stuff are hardwired into the system. I don't want to translate REBOL itself, but e.g. R2 does not allow easily callendar data being translated. Other thing is currency, flating number separator (for display purposes, etc.) |
BrianH 10-Apr-2009 [13206] | The main thing you need system/user/home *for* is to know where to look for %user.r - it is not safe to look for it in the current directory, and not multi-user-friendly to load it from the same directory as %rebol.r. R2 is horribly broken in that. |
Pekr 10-Apr-2009 [13207] | having user.r in current directory is really simplistic though ... |
BrianH 10-Apr-2009 [13208] | And really BAD. It's a security hole. |
Pekr 10-Apr-2009 [13209] | I hate those system specific ways where Windows put it into your profile /somewhere/shitty/really/terrible/brokenly/even/worse/than/linux/long/path ... |
BrianH 10-Apr-2009 [13210] | Oh, do you mean %USERPROFILE%, which is similar to %HOME% on Linux? It's the same either way, really. |
Reichart 10-Apr-2009 [13211x2] | Perk, that is very funny.... thanks. |
I so miss the Amiga's alias command... | |
Pekr 10-Apr-2009 [13213] | BrianH: yes, but I work in Total Commander, and I work with directories. I need to learn how to do some shortcuts, because going down that directories to locate some file is a pain :-) |
BrianH 10-Apr-2009 [13214x2] | I use junction points on Windows all the time - it makes all sorts of things tolerable :) |
Those work at the NTFS level, so Total Commander can use them. | |
Pekr 10-Apr-2009 [13216x2] | Hmm, there is maybe even something like Alias in Windows, no? At least in DOS there was some command .... but - never mind, I went off-topic here ... |
BrianH: do we post R3 beta item list somewhere here in non web-public group, or we keep the link in Chat only? | |
BrianH 10-Apr-2009 [13218] | We're public now. If it is really important that it be quiet, use private chat here or in R3 chat. |
Geomol 10-Apr-2009 [13219] | I think, you mean Amiga's ASSIGN command. It was a very clever feature. |
Pekr 10-Apr-2009 [13220x2] | I will post in Links group, OK? |
BrianH: what is outcome of read/text discussion? I did not like the proposition, because while text operations might be common, text is just format as any other is, so should be decoded using codecs (which can be chained). OTOH just yesterday I used read/lines. I use it very often for external formats, to parse in foreach loop. So - what will be the equivalent in R3? 1) 'read gives me a binary 2) I convert to string 3) then I parse .... or 1) I use load 2) which does read it for me and converts to text using some codec ... but still - where is the place to turn it into line delimited mode? Will we have to use parse rules then, or where would you put something like /lines /with R2 equivalents? | |
BrianH 10-Apr-2009 [13222x2] | READ/text seems like a lock, sorry. You may think that text is just another data format, but it is the *most common* data format, and tends to be processed in large quantities. You say that codecs can be chained, but they currently can't - you can apply them one at a time, with all of the intermediate forms in memory at some point. If we do text the way you ask, then every load of text for processing will have the additional overhead of a full duplicate of the ram and two series moves, plus a few lines of code. READ/text is a shortcut that will save a *lot* of overhead during what may be REBOL's most common operation. |
The /lines refinement of READ has been moved to the DELINE function - try that. | |
Pekr 10-Apr-2009 [13224x3] | I don't agree that text preloading would cause a duplicate. Are you trying to suggest, that codecs are such pigs, that they do first read the whole file, and then decode? Then the system is flawed, because what you do with the 9GB video then? |
BrianH - the thing is, that I don't like exceptions ... :-) ... but I can understand, if some exception covers some 80% of usage cases. REBOL is not about purity, but about practical aproach. But I still don't believe in the explanation you provided :-) and btw - Carl said, that codecs should be chainable, so hopefully it comes? | |
I thought that text (the same as jpg, video, whatever format) will be loaded in chunks needed to identify the format (codec responsibility), so I really don't understand, why text should be twice in memory? | |
Steeve 10-Apr-2009 [13227x2] | So, no way to open a codec as port to inject chunked data ? |
So, no further streaming in Rebol again... | |
Pekr 10-Apr-2009 [13229x2] | Steeve - I posted read/text follow-up to codec Chat section. I really don't like it. I added even your question about ports. I think, that Carl is trying to make his life easier = give me some whole C code for particular format, I will pack it with REBOL via tiny interface. |
Steeve - as a side - note - I posted to Carl link to your editor, and he might blog on it. He just said that now he understands why you wanted virtual blocks :-) | |
shadwolf 10-Apr-2009 [13231x3] | Virtual what for ? |
lol that sounds like a boys band | |
Pekr give CArl the link to the wiki track he will get some of hours past days coding experience what we tried and why we concluded in doing the things the way we do them | |
BrianH 10-Apr-2009 [13234] | Pekr, right now codecs only decode binary! and encode to binary! - I mean values of the datatype binary! that are already in memory. So yes, codecs currently *do* require that you read the whole file first. Streaming isn't there yet. |
