Nested Attribute Dictionaries

[thomthom]

SKP files are for the most of it two-byte UTF-16 encoded. (Some old data blocks appear to be ASCII.) All though, the strings you get from the Ruby API is UTF-8 encoded.

So then is there a normal, and a backup dictionary in the file ?

Backup?

Not sure what you mean.

But when I have inspected .skp files I saw no duplicate of any attributes blocks - and the attributes data blocks where in UTF-16.

` i = 0;
s = ""

while i < 100000 do
s = s + "a"
i +=1;
end`

it's easier in Ruby to do:
s = 'a' * 100000

I'm going to guess it's a bit faster as well.

Yes I meant duplicate internal backups, like how a floppy disk has a backup of the master boot record, that can be restored if the primary gets corrupted. (Not that many are using floppies these days, but it's an example.)

Ruby continues to amaze me, it 'reads' so logical!
Still much to learn...

I wonder if we could use Zlib to compress data before writing it to dictionaries ??

Unzipping it on a read ?

Another neat usage of * is for joining arrays:
[1,2,3,4,5] * ' - '
Returns:
"1 - 2 - 3 - 4 - 5"

I'd love to be able to use zipping in my projects. Think I looked at it some time ago and people had tried to find ways to make it work properyl within SketchUp ruby with mixed results..
