serializing?
[1/6] from: rishi::picostar::com at: 13-Sep-2000 23:19
I've created an object in my source file. I would like to save this object to a text
file, and
later, retrieve this object and use it.
This is called serialization of an object. Is there an easy way to do this in rebol?

Hi!
I wrote a script for serializing any rebol code. It also serializies
values and bindings of words and can serialize recursions. It also
serializes something like "^"{" correctly.
If someone wants to try it out, send an email to [frank--sievertsen--de]
Greetings,
Frank

Have a look at the function SAVE. The counterpart is LOAD.
HTH,

that's just too simple.

Hi Gabriele
Just a small cautionary note. I have recently noticed that SAVE and LOAD do
not always work. For instance, in REBOL/VIEW 0.10.33.3.1
>> layo: layout [box 200x200 red]
layo is a face object.
>> view layo ;works fine
>> save %layo.sav layo ;writes a large file (about half a megabyte)
The file contains indicators of recursive blocks/objects i.e. [...]. So it
will not load back in a valid form.
>> layo2: load %layo.sav
>> view layo2 ;no red box
I have reported this to feedback, but had no response so far.
