DocKimbel 28-Jul-2013 [9727x2] | You compile the script for full Unicode support for now. |
You <should> compile... | |
Gerard 28-Jul-2013 [9729] | hello |
DocKimbel 28-Jul-2013 [9730x2] | Hey Gerard :) |
For named characters like "^(line)", IIRC, we don't support it yet. | |
Gerard 28-Jul-2013 [9732x5] | It seems I already did it without having seen the right results but now it works ... : ) |
OK For your information about what I have done today for the introduction to the Perl Cookbok just go to the REBEL BB forum and see my last post, it will be quicker to judge by yourself. - please you can comment too if you have some time. but LEt the others do the real work for revision and correction please. | |
I noticed your answer for the escaped chars | |
Is it the same for the other codes given in the Rebol 3 doc ? as for example when I type #"^(3B1)" in the Red console, I get some errors too ... | |
I suppose it is the same case as the one before ... | |
DocKimbel 28-Jul-2013 [9737] | when I type # ^(3B1)" in the Red console, I get some errors too ..." The console script for Red supports only ASCII input. :-) |
Gerard 28-Jul-2013 [9738x3] | OK but in a sense what I typed is in full ASCII, isn't ? |
Thanks Doc and I leave you now - going "à la soupe"... You will soon go to bed too I suppose. | |
Glad you came back already and safe | |
DocKimbel 28-Jul-2013 [9741] | Yes, you input ASCII characters, but the runtime lexer needs to decode your Unicode codepoint in hex format, and the lexer has no support for that. |
Gerard 28-Jul-2013 [9742] | OK that's already fine as is for now. |
DocKimbel 28-Jul-2013 [9743] | Right, I'm not far from going to bed. ;-) |
Gerard 28-Jul-2013 [9744x2] | Keep up the good work - i'll support you by means of other donations, as soon as my next cheque is coming in. |
Must go back to some real work now - I just played all the day with these other websites and books ... | |
DocKimbel 28-Jul-2013 [9746] | Thanks Gerard! I'll have a look at your posts on RebelBB and will send you my comments, if any. |
Arnold 28-Jul-2013 [9747] | Results for the initialized state-table are now the same, finally. Thanks! |
Arnold 29-Jul-2013 [9748x2] | Red/System: Could it be that if you #define MAX-SIZE 100 my-array: as int-ptr! allocate MAX-SIZE * size? integer! then using my-array/MAX-SIZE gives a compilation error?? *** Compilation Error: undefined pointer index variable |
Probably food for an issue? | |
DocKimbel 29-Jul-2013 [9750] | I remember that we allowed macro replacement in paths, but it might be only for macros with parameters. Have you found an existing ticket about that? |
Arnold 29-Jul-2013 [9751] | doesn't look like it. |
Kaj 29-Jul-2013 [9752x4] | That may indeed very well have been only about macro parameters |
You could work around it: | |
i: MAX-SIZE | |
my-array/i | |
Arnold 29-Jul-2013 [9756x2] | Right but then I have a #define macro AND a variable. So I had better started of with the variable in this case. |
But is really is a constant. | |
Kaj 30-Jul-2013 [9758] | Yes, it's imperfect |
Arnold 30-Jul-2013 [9759] | That is why I created an issue for it #504. |
DocKimbel 30-Jul-2013 [9760] | I'm finishing installing the tools I need and migrating all my data from old disks, I should be able to get back to full coding tonight....finally. |
Kaj 30-Jul-2013 [9761] | Such things always take a lot of time |
Arnold 30-Jul-2013 [9762x2] | I reached this: C code: hex value 2214165945 is=0x83f97db9 * 1664525 gives 32710463130033 plus j 0 and plus the init_key of value 291 mt[i] 32710463130324 and(&) FFFFFFFFh results in mt[i] 4287171284 Red/Systemcode -2080801351 which is also (to-hex -2080801351) == #83F97DB9 multiplied by 1664525:: 1658067045 and then added also 291 and 1 minus 1 state-array/i: 1658067336 |
(My) Conclusion the multiplication by 1664525 causes the results of the C source and Red/System source to diverge, possible reason calculation with long integers in C versus integer calculation in Red/System troubled by overflows. | |
Kaj 30-Jul-2013 [9764] | Is that on a 64 bit machine? |
Arnold 30-Jul-2013 [9765x2] | It is my Macbook from 2008. |
That is 64 bit but not the core or something, that is why it can't upgrade beyond Snow Leopard. | |
Kaj 30-Jul-2013 [9767x4] | It must be 64 bit, because a long on Mac would probably be 84 bit there. Indeed, your multiplication result is 64 bit, so on Red/System, it is wrapping around |
64 | |
However, the algorithm should also work on 32 bit, shouldn't it? | |
Or is it using long longs? | |
Arnold 30-Jul-2013 [9771] | Yes, there is a trick to AND with FFFFFFFFh to bring it back to 32 bits, but harm to the resulting values has been done then. |
Kaj 30-Jul-2013 [9772] | Not if the algorithm is meant to work on 32 bit |
Arnold 30-Jul-2013 [9773] | I have no idea how to compile and run the C variant in 32 bit mode |
Kaj 30-Jul-2013 [9774] | There would be some compiler option, -32 or something |
Arnold 30-Jul-2013 [9775x2] | That was easy on XCode. Getting closer now. (still differences :( ) |
(changing target) | |
