CharlesS 23-Feb-2007 [7311] | can the to function translate to user defined structures / objects ? if so how, is there a special method name in the object you want to convert to ? |
Sunanda 23-Feb-2007 [7312] | If I understand your question, Charles, you may be looking for construct/with......It's a way of using an existing object as a template for a new one, eg: my-obj1: make object! [a: 99 b: 2 c: "string"] my-obj2: construct/with [b: 9999] my-obj |
Henrik 24-Feb-2007 [7313] | hmm... is it possible to find () elements in a block? they don't have a specific datatype. find [a b c (code) d] ?? ; what type? |
Sunanda 24-Feb-2007 [7314] | Is this a start? find [a b c (code) d] paren! |
Henrik 24-Feb-2007 [7315x2] | ah, precisely, thanks. didn't know there was a type for them |
because: type? () == unset! | |
Sunanda 24-Feb-2007 [7317] | And, perhaps worse: type? (1) == integer! which is not what you might expect..... You have to do this to get type? to work: type? first [(1)] == paren! |
JaimeVargas 24-Feb-2007 [7318x2] | The parens! triger evaluation so type? (1) = type? 1 ;== integer! |
But parens inside blocks are not evaluated. | |
Robert 25-Feb-2007 [7320x2] | Is there a way to find out if a loaded file is encrypted with CLOAK? |
Or do I have to read it and try to DECLOAK it? | |
Sunanda 25-Feb-2007 [7322] | As far as I know, an encloaked string is just a jumbled up, binary version of the original string: it carries no prefix signature so you can't tell at a glance it is an encloaked string rather than another bit of binary. So, yes, as far as I knoww, you'll have to read and attempt decloaking. Or, if you have control over the writing, ensure some sort of identifiable prefix is added) |
Henrik 25-Feb-2007 [7323] | >> do to-path reduce ['now 'none] ** Script Error: now/none has no refinement called none ** Near: do to-path reduce ['now 'none] >> do to-path reduce ['now none] == 25-Feb-2007/20:40:18+1:00 >> do probe to-path reduce ['now none] now/none == 25-Feb-2007/20:40:28+1:00 >> now/none ** Script Error: now has no refinement called none ** Near: now/none I guess the difference is between 'none and none!, but I thought it was curious that the none! is accepted as a refinement. |
Anton 25-Feb-2007 [7324x2] | >> now/#[none!] == 26-Feb-2007/14:28:03+11:00 |
Actually it looks like you can put any issue! >> now/#hello == 26-Feb-2007/14:28:43+11:00 | |
Gabriele 26-Feb-2007 [7326] | functions just ignore anything that is not a word in the path. |
Robert 26-Feb-2007 [7327] | DECLOAK: I have the problem that a random char is added as the first char to a decloaked string. Is this a known problem? |
Anton 26-Feb-2007 [7328x3] | Not to me it isn't. What version of rebol ? |
It's not in Rambo. | |
encloak / decloak seem pretty stable to me. Be aware that these functions modify the string you pass it. | |
Robert 26-Feb-2007 [7331] | I only have the problem when not using read/binary but just have used WRITE and READ... strange. |
Oldes 26-Feb-2007 [7332] | Just don't use just WRITE with encloked data as these data are binary data. |
Gregg 26-Feb-2007 [7333] | I've never had a problem with encloak/decloak, but I would also avoid string ops that might translate the binary data somehow. |
Anton 27-Feb-2007 [7334] | Yes, READ and WRITE are in text mode and translate line terminators, so LF can become CRLF and vice versa. |
Oldes 27-Feb-2007 [7335] | Is there any better way how to convert issue! to binary! than this silly one? issue-to-binary: func[clr ][load head insert tail insert next mold clr "{" "}"] |
Maxim 27-Feb-2007 [7336] | and what do you want... the string or the value? |
Oldes 27-Feb-2007 [7337] | I want binary value |
Maxim 27-Feb-2007 [7338x2] | so four byte issue gives 32 bite value... |
or is initial issue a decimal type integer? | |
Oldes 27-Feb-2007 [7340x3] | >> issue-to-binary #ff0000 == #{FF0000} |
at this moment as-binary is working like: >> as-binary #ff0000 == #{666630303030} | |
which i really don't like | |
Maxim 27-Feb-2007 [7343x3] | I know... both are valid . |
same for tuples, etc. | |
for going to-from hex... I don't have a solution. | |
Oldes 27-Feb-2007 [7346x2] | it's stupid behaviuor. I really don't know what it can be good for, as I can always do: >> as-binary next mold #ff0000 == #{666630303030} |
ech, I know why it's molded as string - issue can hold any value... :( so my Rambo wish is pretty stupid now:-) | |
Ladislav 27-Feb-2007 [7348x2] | issue-to-binary: func[clr] [debase/base as-string clr 16] |
issue-to-binary: func[clr] [debase/base clr 16] | |
Oldes 27-Feb-2007 [7350] | YES :-) that's much more better, thanks. |
Gabriele 28-Feb-2007 [7351] | oldes, do you want me to delete that ticket or should i keep it? |
Oldes 28-Feb-2007 [7352x2] | yes please |
delete it as it's a nonsense | |
Gabriele 1-Mar-2007 [7354] | done |
Maxim 1-Mar-2007 [7355] | (Oldes, just so you know, in english "more better" makes no sense. better implies more. ( I'm saying this just cause I've seen you write it a few times ;-) |
Henrik 2-Mar-2007 [7356x2] | continuing from AltME: of course now that I think of it, launch/quit will always restart the app rather than run the script I made. :-/ |
using enbase 64 isn't safe for filenames is it? | |
Sunanda 2-Mar-2007 [7358] | Do you mean using it to generate file names that will be acceptable on any platform that REBOL runs on? If so, I don't know, but I wouldn't take the risk..... ....I use checksum/secure and remove #{} part -- gets me a file name that is just letters (a-f) and digits. |
Gabriele 3-Mar-2007 [7359x2] | i think base 64 uses / |
henrik: the detective only updates the interpreter if it is needed; when it is needed, it downloades the new version as update.exe, and runs it, then quits. update.exe overwrites the main executable with itself then launchs it and quits. there is no other way on windows that i know of. | |
