Question about Lube.bin:pack

Post by Mr. Strange » Fri Oct 08, 2010 7:06 am

I've got this working on tables for which each element is a value - but it seems to choke on tables which have other tables as elements.

Is that the intent? Or is there some way I can make this work without adjusting my data structure?

Define "choke".

(maybe with some code example, and the desired result)
When I write def I mean function.

I have a table in this form:

example = {
name = myName,
pos = { x = 0, y = 0},
color = "red",
}

When I call lube.bin:pack(example) I get an error message which says : "Type table is not supported by lube.bin"

If I remove the sub-table (the pos = {} line) and replace it with a variable, it works fine. So my conclusion is that I can't pack a table which includes tables as elements. This seems really limiting - but maybe that's just because I have unreasonable expectations?

I could do something like write a manual pack function - but that seems silly. The pack function looks like it could easily be modified to include tables as a supported type - of course this makes the function somewhat recursive, which is maybe a frightening thing.

In any case, I hope that clears up my question

No, the thing is, the code isn't smart enough to recognize embedded tables, you can however, change the special characters, pack the subtable with it, switch back and pack a table with the pre-packed string. Oh, and that sucks I know, but lube.bin, like lube.easy isn't really advanced, in fact, I remember writing a notice somewhere about it being mostly for reference/learning/base/whatever.

Since my last post I re-wrote lube.bin:pack to pack tables as well, but then I realized that since the elements in the sub-table are spaced with null characters just like the elements of the parent - unpack can't differentiate.

Crap.

Well, unless someone steps up to write a more intelligent recursive unpack mechanism, I guess I'll have to re-structure my data. Grrr...
