#2130 — Any free software to help plan data structures

I usually use paper to plan out data structures such as drawing these
objects in boxes

  node:
    prev ptr
    next ptr
    parent ptr
    address

  page:
    base
    increment

and sometimes with arrows between them. (I might draw multiple of the
above nodes, for example, to help me visualise the processing. So
there is not just one definition per type.)

Paper is OK for small projects or where there are not too many
changes. For complex objects with lots of changes and for big projects
a software package might be better.

Anyone use or know of some good free software to allow such sketching?
It could even generate structure definitions in various languages so
would be more than just a drawing package but the sketching and
changing are the most important things.

If you are looking for a way to draw diagrams then you could give Dia a try.

If you prefer to plan your code by laying out some UML diagrams then there 
are some UML tools available, some of which are also able to generate code 
from your diagrams.  Umbrello comes to mind, although it has its flaws.

http://uml.sourceforge.net/


Hope this helps,

Many thanks Rui, those seem to be good options.
