Pekr 22-Sep-2009 [17946] | Max - who decides, what EITHER mean in parse context? We do. I can say - don't use COPY, as this is not what is happening (in REBOL's copy function semantics equivalence) |
Maxim 22-Sep-2009 [17947] | but copy actually does copy what is being parsed. either isn't comparing a value like the if PARSE statement. |
Pekr 22-Sep-2009 [17948] | Max - you are NOT in REBOL level, so free yourself from pedantic "EITHER uses this syntax" equivalence, or dismiss COPY keyword too - it absolutly does not fit REBOL and even today on blog I had to fix Ingo's type, where he ommited to provide parse COPY with word to copy to ;-) |
Maxim 22-Sep-2009 [17949] | but in the end, I just dont want it to be + which is the worst... even "?" prefix is better |
Pekr 22-Sep-2009 [17950x3] | Once again - free yourself from REBOL, gee. Who said said EITHER should compare anything? Copy breaks normal copy rebol logic. VID 'at command is completly different in semantic meaning to REBOL 'AT. So - how is that that for EITHER we do care about what it means in REBOL? The word EXACTLY expresses what you are doing ... |
If you want to be so pedantic, let's exclude all word from parse, which have different meaning in REBOL. It means COPY, TO ... any other candidate? ;-) | |
Today I posted more philosophical topic, and Carl noticed it - we ares shooting ourselves in the foot. Here's what I posted: ------------------- There will always be problem with dialects, if they contain the same keyword names as REBOL functions. So we have to somehow live with that. So the question is, where to introduce new name and why, just to be different, and where to not. E.g. parse 'copy keyword has already different semantics to REBOL's one, or VID's 'at has different semantics to REBOL's one. Now can users be confused? It depends. I try to think about each dialect in the context of the dialect itself - so the only measure for me actually is, when reading the source code (or trying to understand one's), how quickly I am able to understand, what is going on? But then we could as well replace 'stay by 'save-position, 'of by 'any-of, 'if by 'only-if, etc., which would imediatelly map the meaning to what the keywords are really doing. But we are somehow mysteriosly looking for one-word-only-mantra naming convention, and I suppose it is already our style, and we will not change it :-) ... so, the topic is a little bit more abstract - it is about contexts, and user/programmer switching between contexts, and his/her ease of understanding of the code. In above case, all 'if, 'check, 'either are OK, even if their semantics is a bit different to their REBOL counterparts. | |
Maxim 22-Sep-2009 [17953] | I do agree |
Pekr 22-Sep-2009 [17954] | your rant towards EITHER not fitting anything breaks the initial purpse dialecting was brought to REBOL! And the meaning is - the same word, might mean different things in various contexts. We don't care for VID to use potentially the same keywords to REBOL functions, let we do care somehow mysteriously about PARSE to NOT use the same keyword naming as REBOL functions. Let's judge EITHER by its name, not by its REBOL level meaning. |
BrianH 22-Sep-2009 [17955x2] | Yeah, the name EITHER, exactly the reason I've had a problem that proposal since it was proposed in December. |
The name EITHER was why I put "maybe" on the proposal. | |
Pekr 22-Sep-2009 [17957] | If the english meaning of EITHER does not describe well what is intended, then let's not use it, otherwise let's use it. I noticed Carl created scenario, which allows to be really flexible. If no word can fit its meaning properly, then let's use the symbol. If we can find word for it, which will help users to imediatelly see, what the code does, let's use the name with no prejudices ... |
BrianH 22-Sep-2009 [17958] | It doesn't. |
Maxim 22-Sep-2009 [17959] | not with carl's last example and syntax, but using blocks it would... without any lost in capabilities. |
Pekr 22-Sep-2009 [17960x2] | I might agree with Max here -sometimes I prefer already existing syntax being reused, instead of coming-up with additional semantic jumbo-mumbo :-) |
It definitely is not an easy decision. I would proceed as following - take Carl's examples, and try to express/describe them in human words - simply how you would write a manual for them. The look at what you wrote once again, and if you find there is plenty of "either" words, then use it :-) | |
Maxim 22-Sep-2009 [17962] | my point is just that blocks will be used so often anyways, because of recursive rules, that I see no point in using "|" as I say, in every complex parse I've done, I have to separate the "|" by blocks anyways... they just don't roll-back very well in practice. |
Pekr 22-Sep-2009 [17963] | ah, you are a purist, you would remove even | ? :-) |
BrianH 22-Sep-2009 [17964] | Not in R3, they work fine. And any bugs will be fixed. |
Maxim 22-Sep-2009 [17965] | pekr, not in the general rule, cause otherwise we'd need some new word to say "OR" these blocks. |
Pekr 22-Sep-2009 [17966] | The only problem I have with | is where to put it in multi-line rules - end of line, or new line? :-) |
Maxim 22-Sep-2009 [17967x3] | but brian... ALL real parse rules are so complext that we need to properly define the groups of "|" between them... so the point is moot even if they do work better now. |
we still need to put rules in blocks, just about all the time. | |
and now with carl's example this will be even more so. | |
Pekr 22-Sep-2009 [17970x2] | Max - we want to sensibly extend/fix parse, not to break what we are already used to, no?:-) |
5:16 here ... should continue my sleep, I woke up at 3:00, or I will look drunk at work :-) .... | |
Maxim 22-Sep-2009 [17972] | hehe, don't get me wrong, I like that R3 PARSE is finally being addressed... I think carl waited sooo long because he knew there would be a storm about it ;-) |
shadwolf 22-Sep-2009 [17973x4] | i started the port of areatc to rebol 3 ... so far i hate the way to stilize gobs all those words to put every where yeeeeeeeeeeeeerk ... my gob does already more than 10 lines and do nothing on screen !!! |
stylize [ area-tc : [ about: "Area displaying in color keywords in text" facets: [ size: 400x400 max-size: 2000x2000 ] options: [ size: [pairs!] ] faced: [ ] ; internal face funcition: ; events handler actors: [ ] ] ] | |
i ned some help what is the equivalent of init in R3/VID ? and is there a draw: embeded to a gob how can i say my custom face inherits from box style ? | |
found how inheriting box style | |
shadwolf 23-Sep-2009 [17977] | hum apparently text instruction in draw doesn't apply colors ! |
BrianH 23-Sep-2009 [17978] | The R3 equivalent of VID isn't done yet, and some revisions are planned. |
shadwolf 23-Sep-2009 [17979] | hm ? i'm using VID the demo one and i'm not in a good mood !!! What the fuck is that shit is that the improvements i heard about during month and month ? So to be simple and keep my cool i will not port area-tc or viva-rebol to R3 until it's finished |
BrianH 23-Sep-2009 [17980] | The improvements have been to lower-level parts of R3. The work on the GUI made it abundantly clear that the lower levels needed some work. We've been doing that work. Part of that is the parse imoprovements that we're working on right now, which will help with improving the VID dialects. |
shadwolf 23-Sep-2009 [17981] | load-gui ; area-tc stylized gob -custom widget- areatc-obj: context [ stylize [ area-tc: box [ about: "Area displaying in color keywords in text" facets: [ size: 400x400 max-size: 2000x2000 ] options: [ size: [pair!] ] faced: [ ] ; internal face funcition: ; empty draw block ... draw: [ fill-pen red text 20x20 [ "test" ] ] ; events handler actors: [ ] ] ; fin area-tc style ] ; end stylize ]; end areatc-obj view [ area-tc ] to draw in the end a black text over a background default colored with a shape and color i didn't choosed that's not not not cool at all too much code for a useless thing and a wrong result. |
BrianH 23-Sep-2009 [17982] | Carl has some new ideas that will help fix the resize model, and we will be working on those when work on the GUI resumes. |
shadwolf 23-Sep-2009 [17983] | yeah around 2012 and meanwhile I wait ... pfff ok since carl is actually working on parse to make it more friendly to idiots like me I will say i will wait. |
BrianH 23-Sep-2009 [17984x2] | Hew, I've been waiting for the parse enhancements for 5 years, or more recently since November. You won't have to wait that long. |
Hew -> Hey | |
shadwolf 23-Sep-2009 [17986x2] | I'm frustrated max ... i saw carl working on parse i wanted to take that opportinuty to start adapting area-tc to r3 and VID just is unfinished not even exploitable to do a starting of a begining of a test work .... i though text instruction as been reformed last time carl working on GUI and that we could use thing like text pos [ color1 "string1" color2 "string2" color3 '"string3" etc ...] |
but in fact that's the same old draw we had in R2 ... | |
BrianH 23-Sep-2009 [17988] | The Unicode enhancements haven't made it to the GUI yet. We haven't been working on the GUI since spring. |
shadwolf 23-Sep-2009 [17989] | hum apparently the sting arguments in text draw is able to "rejoin" strings given in a block and you can't give strings to text instruction without embeding them to a black |
BrianH 23-Sep-2009 [17990] | It took a while to even propagate the Unicode and moduule changes across the core, let alone the GUI. |
shadwolf 23-Sep-2009 [17991] | yeah ... i believed what people told me you can almost use Vid to do area-tc thing is it's not the case at all ... |
BrianH 23-Sep-2009 [17992] | Oh, which people? Never mind, it doesn't matter. |
shadwolf 23-Sep-2009 [17993x2] | button "Close" [quit] that doesn't work neither ? what i have to do then button "Close" with [actor: [ on-lick: [quit]] ] ? |
ho it's button "close" do [quit] | |
BrianH 23-Sep-2009 [17995] | button "close" quit |
