Nick T (ntrel) suggested we move discussion of a symbol tree patch to the list

I'm not exactly sure what you mean - I thought that parsing the symbol
names was the only way to determine symbol tree structure?

E.g. given a list of symbols


We can construct a tree:
 |_ b

The information on the tag type is simply used to determine the
icon/type to use in the tree.

Yes, presorting sounds like a good idea to avoid modifying the list of
symbols. FWIW the current logic is to move a symbol to the end of the
list if its parent cannot be found.

Note that the 'skipped' list is actually not used in the current
version of the patch - it was there to catch errors caused by a bug in
the the C++ tag generator (nested namespaces, see bug "[ 2141317 ] C++
nested namespace tags created incorrectly")

Of course you're welcome to do that - I'm simply happy to have the
feature since it really helps navigating complex code.

Thanks again for your and all the other geany developers' work :-)
