Oldes 2-Jun-2006 [4809x4] | Nut if I understand it well, you need content of variable which is stored in the wordStr |
(nut = but) | |
>> w: "someWord" == "someWord" >> reduce [to-word w] == [someWord] >> find first system/words 'someWord == [someWord] | |
but this is interesting: >> length? first system/words == 2600 >> newword ** Script Error: newword has no value ** Near: newword >> length? first system/words == 2601 | |
Gordon 2-Jun-2006 [4813x2] | Thanks but WordStr is a string and I need it to be a word type. |
Actually, you are right. Thanks Oldes. I was able to write it all to the file then read it back in and parse it into 'words' without using 'to-word'. | |
Anton 4-Jun-2006 [4815] | This is a frequent stumbling block with beginners - using more words than necessary. Words are really good at expressing distinct concepts (ie. variables). If you have lots of similar data, then that really just calls for a series. |
Graham 4-Jun-2006 [4816x2] | Anyone tried printf from the library? |
>> do %printf.r >> printf ["%d" .02 ] ** Access Error: Cannot open sprintf ** Where: routine-call ** Near: routine: make routine! spec library | |
Gabriele 5-Jun-2006 [4818] | note that r3 will make it easier to create non-bound words (i.e. symbols) for the cases when you want to use words as symbols (dialects, data, etc) and not variables. anyway, as anton says, i don't think anyone would ever really need more than 8k distinct words, so when you get that error it means that probably you are doing something wrong :) (ah, and given that contexts are extensible in r3, i expect the 8k word limit to go away) |
Pekr 5-Jun-2006 [4819] | Gabriele - as you mention dialects, will parse see any changes/enhancements in R3? Just curious :-) |
Gabriele 5-Jun-2006 [4820] | maybe. we've been discussing a few things. nothing decided yet. |
Anton 5-Jun-2006 [4821] | I wonder if beginners will take longer to realise the error of their ways... |
Gabriele 5-Jun-2006 [4822] | anton, yes that could be an issue. maybe we could have a soft limit or something like that for contexts. but, i don't know if there's an hard limit, i'm just assuming there isn't, but i may be wrong. |
Anton 5-Jun-2006 [4823] | They'll find the hard limit when they exhaust memory. :) |
Pekr 5-Jun-2006 [4824] | :-) |
JaimeVargas 5-Jun-2006 [4825] | Graham, I bet printf is not finding the either the DLL or the function on the DLL. |
Graham 5-Jun-2006 [4826] | Is this a standard windows dll? |
JaimeVargas 5-Jun-2006 [4827x2] | Yes. |
Humm. It seems that WinXP' kernel32.dll doesn't includes the sprintf function. I will apreciate if anyone can point to the proper DLL. | |
BrianH 6-Jun-2006 [4829x2] | msvcrt.dll |
That is the C runtime. There are a few other (older) C runtimes on Windows, but that is generally the best one. | |
JaimeVargas 6-Jun-2006 [4831x2] | Thanks Brian. |
New printf.r script with fix commited to the library. | |
Graham 6-Jun-2006 [4833] | Thanks. |
JaimeVargas 14-Jun-2006 [4834x6] | Humm. I give up. Has somebody found a solution to the path capture problem? #!/usr/local/bin/rebol -sq REBOL [] print first system/options/args |
What I need is to be able to capture the full path of the first arg passed to such script. | |
Not just the filename. | |
The reason is that the script is no of the same path of /usr/local/bin the script fails to find the file. | |
Which is passed as arg | |
Hopefully this is not too convoluted... | |
Gabriele 14-Jun-2006 [4840] | if you encap it, the CD will be the dir where the program was started from. when run with a shebang though... not sure if there's a way. |
JaimeVargas 14-Jun-2006 [4841] | No SDK in OSX :-/ |
Ingo 14-Jun-2006 [4842] | Hi Jaime, I think you're looking for this system/script/path |
Volker 14-Jun-2006 [4843x2] | probe system/options |
IIRC the shell-dir is somewhere there. Or try system/options/script/parent/path. | |
JaimeVargas 14-Jun-2006 [4845] | Thx, Ingo and Volker, what I was looking for is SYSTEM/OPTIONS/PATH |
BrianW 14-Jun-2006 [4846x6] | Dumb question: When I'm printing a string, what's the best way to show special characters (^/ etcetera) in their special form, rather than just expanding them (turning ^/ into an actual newline, for example)? |
well, I know probe is the way to do it direct to stdout, but I want to save the "probe" value to a string | |
and for the public record, at least part of my answer is: raw-str: mold real-str | |
yay for "source probe" | |
How about going the other way? Turning newlines into ^/ characters and so on? | |
and again I answer my own bloody question: replace/all (mold real-text) "^/" "^^/") Guess I don't actually start thinking for myself until I ask the question somewhere that I can look dumb ;) | |
Izkata 14-Jun-2006 [4852] | But that's the best way - you're more likely to remember it then! |
james_nak 15-Jun-2006 [4853] | Is there a way to "copy" an object (already defined) so the result is a distinct object? It's probably something easy but for the life of me... |
Anton 15-Jun-2006 [4854] | make |
james_nak 15-Jun-2006 [4855] | Thanks Anton. Yep, right after I wrote that I said to myself "Self, why don't you try 'd: make c [ ]'" and it works...and it is in the docs on objects. Duh. Thanks. |
Anton 15-Jun-2006 [4856] | :-) |
BrianW 15-Jun-2006 [4857] | Good to know I'm not the only one :) |
james_nak 15-Jun-2006 [4858] | You kidding? I hate it when I spend hours trying to figure out what's up. : ( |
