Maxim 29-Apr-2009 [13752] | but the skip becomes pretty useless, as you can get the inner records of the skip. |
shadwolf 29-Apr-2009 [13753] | BrianH hum same for me ... |
Maxim 29-Apr-2009 [13754x2] | the /skip in many functions are implied records... and the reason they are there... not getting the record as a return values... is an oxymoron IMHO |
I still discover new functions after 9 years too :-) | |
BrianH 29-Apr-2009 [13756] | Maxim, are you in favor of the R2 behavior or the current R3 behavior? Or something else? |
Maxim 29-Apr-2009 [13757x2] | R2 |
the R3 return sort of alleviates the point of the /SKIP refinement no? | |
BrianH 29-Apr-2009 [13759] | So am I. I wasn't saying I preferred it, just that I expected it. I think this is why I've never used select/skip :( |
Henrik 29-Apr-2009 [13760] | The R2 method is much more flexible. The R3 method is identical to "first select/skip", and I doubt there would be that much gained by having a specific alternative function for the R3 method. |
BrianH 29-Apr-2009 [13761] | I prefer the R2 method - I bet noone expected me to ever say that :) |
Henrik 29-Apr-2009 [13762] | BrianH, not working much with flat blocks, eh? |
Maxim 29-Apr-2009 [13763x2] | its like sort/skip there is a simple consistency in the implied records which I always like... other languages will have a framework just for that... |
brian: LOL | |
BrianH 29-Apr-2009 [13765] | I tend to use FIND and SET [w1 w2 ...] |
Maxim 29-Apr-2009 [13766x2] | but find will trip if records ands content can have the same datatypes... wich is why the /skip refinement makes sense. |
(for select) | |
BrianH 29-Apr-2009 [13768] | Sorry, FIND/skip |
Henrik 29-Apr-2009 [13769] | Maxim, yes. I'd say that if every single REBOL function used /SKIP consistently, you could do flat block databases and rely on /SKIP without getting your records screwed up. |
Maxim 29-Apr-2009 [13770] | its almost the case now... sort/skip find/skip select/skip |
Henrik 29-Apr-2009 [13771] | hey, here's a fun one: a: [1 2 3 4 5 6 7 8] select/skip a 5 -4 hangs. |
Maxim 29-Apr-2009 [13772x2] | which function is fundamentally different in this regards ?.... I don't seem to recall one off the top of my head |
(in regards to /skip) post order makes my last post a bit out of context | |
BrianH 29-Apr-2009 [13774] | Henrik, is that in R2 or R3? |
Henrik 29-Apr-2009 [13775x7] | R3. |
I noticed something weird too. If you have multiple R3 windows open and switch between them, does the window title change? | |
select/skip issue submitted to curecode. | |
The window title thing seems to be related to marking up text in the console and is not caused by R3. Never noticed that before. | |
it seems FIND/SKIP does the same thing. :-) | |
Alpha 50 released. | |
7 reports with /SKIP issues. | |
BrianH 29-Apr-2009 [13782] | Clearly we are going to need a /SKIP doc in R3/Language/Options. |
Henrik 29-Apr-2009 [13783] | Agreed. |
BrianH 29-Apr-2009 [13784] | I wrote MOVE, so talk to me. How should MOVE with negative skip work? Allowed or denied? |
Henrik 29-Apr-2009 [13785x2] | I don't really know. I guess we want consistency? |
From what I can see the correct way is to provide an out of range error on less than zero. | |
Maxim 29-Apr-2009 [13787] | move is like next but modifies the series itself? |
BrianH 29-Apr-2009 [13788] | We don't have consistency, so I figured I'd start with a fuunction I understand. |
Maxim 29-Apr-2009 [13789] | should say move is like skip |
BrianH 29-Apr-2009 [13790x2] | No, move actually moves stuff. |
move: make function! [[ "Move a value or span of values in a series." source [series!] "Source series" offset [integer!] "Offset to move by, or index to move to" /part "Move part of a series" length [integer!] "The length of the part to move" /skip "Treat the series as records of fixed size" size [integer!] "Size of each record" /to {Move to an index relative to the head of the series} ][ unless length [length: 1] if skip [ offset: offset * size: max 1 size length: length * size ] part: take/part source length insert either to [at head source offset] [ system/words/skip source offset ] part ]] | |
Maxim 29-Apr-2009 [13792] | ok, like a change remove combo |
BrianH 29-Apr-2009 [13793] | Right, but safer. |
Henrik 29-Apr-2009 [13794] | BrianH, do we want consistency across all /SKIP or not? That is a big issue. Personally I would like it. |
BrianH 29-Apr-2009 [13795] | We want consistency. We don't have it yet. So this is a start. |
Henrik 29-Apr-2009 [13796] | OK. The solution would be to generate an out of range error for skip <= 0. DIFFERENCE does that correctly. |
BrianH 29-Apr-2009 [13797] | I wrote the other standard option specs after much discussion. We need that discussion before I can write the /SKIP spec. |
Maxim 29-Apr-2009 [13798] | I would really like the /skip to be consistent as "implied fixed record" it would make flat record management and "explicit" feature of REBOL. |
BrianH 29-Apr-2009 [13799] | Right. |
Maxim 29-Apr-2009 [13800x2] | I second out of range error ... including for partial records if it goes beyond the last complete record |
the partial (last) record consistency is part of the /SKIP feature set wich must not be forgotten. | |
