save versus load

Post by newdep »

Hi Lutz,

when I save with 'save this is the result in that file ->

(set 'data '(49 79 45 76 64 58 4e 79 4c 32 4a 70 62 69 39 75 5a 58 64 73 61 58 4e
77 43 6a 73 37 49 47 56 34 59 57 31 77 62 47 55 67 64 47 56 34 64 41 6f 6f 63 48
4a 70 62 6e 52 73 62 69 41 69 58 47 35 63 63 6c 52 49 53 56 4d 67 53 56 4d 67 52
56 68 46 51 31 56 55 52 55 51 67 52 6c 4a 50 54 53 42 58 53 56 52 49 53 55 34 67
54 6b 56 58 54 45 6c 54 55 43 46 63 62 6c 78 79 49 69 6b 4b 4b 47 56 34 61 58 51
70 43 67 3d 3d))


If I then go on the newlisp prompt and do ->
>(load "test")

Then this is the output -->

> (load "test")
true
> data
(49 79 45 76 64 58 4 e 79 4 c 32 4 a 70 62 69 39 75 5 a 58 64 73
61 58 4 e 77 43 6 a 73 37 49 47 56 34 59 57 31 77 62 47 55 67 64
47 56 34 64 41 6 f 6 f 63 48 4 a 70 62 6 e 52 73 62 69 41 69 58
47 35 63 63 6 c 52 49 53 56 4 d 67 53 56 4 d 67 52 56 68 46 51 31
56 55 52 55 51 67 52 6 c 4 a 50 54 53 42 58 53 56 52 49 53 55 34
67 54 6 b 56 58 54 45 6 c 54 55 43 46 63 62 6 c 78 79 49 69 6 b
4 b 4 b 47 56 34 61 58 51 70 43 67 3 d 3 d)


Do you see the difference? 'Load does manipulate the data list !!

How come? I thought it was a one on one copy?

another example ->

--- file t1 contains this ->
(set 'a '( 1a 1b 1c 1d 1e 1f ))
(set 'b '( aa bb cc dd ee ff ))
(set 'c '( a1 b1 c1 d1 e1 f1 ))
(set 'd '( 1A 1B 1C 1D 1E 1F ))


> (load "t1")
true
> a
(1 a 1 b 1 c 1 d 1 e 1 f)
> b
(aa bb cc dd ee ff)
> c
(a1 b1 c1 d1 e1 f1)
> d
(1 A 1 B 1 C 1 D 1 E 1 F)
>

This means i can never use HEX numbers in a list and 'load it...

So it seems that LOAD does eveluate because its not a string that
is inside the list. Oke fine.. But how to bypass this? Its much more
work to (read-file t1) evaluate it and but it inside to code.. thats why
i tried 'load.. Mmmmmmm

actualy... (read-file) and (read-buffer) convert to string data..
I like/need the way Load handles the data..that 100% newlisp interaction..

1a 3b etc will be parsed as 1 a 3 b etc. thats just how the syntax parse rules work.

Do your (set 'data '(...)) in an intecative window to see:

Code: Select all

> (set 'data '(3a 4b 8f))
(3 a 4 b 8 f)
> 
Instead put this in your file, when you deal with hex values

Code: Select all

(set 'data '(0x3a 0x4b 0x8f))

You know what I like about newlisp!?

Its so addictive that I cant leave my fingers from trying more than
one solution ;-)

Thanks!
