Note that the value of a dereferenced char pointer is a character and not a string, so dereferencing must not be done in this case as gdb already displays the string when printing a char pointer. Also I believe that a pointer to a pointer should not be dereferenced. >> Thanks!

Pretty printing in gdb is already available (since gdb 7.0) through python scripting. It is configurable and values that are printed in the vim balloon follow the configured gdb pretty printing rules. See an introduction to gdb pretty printing made by Tom Tromey in the following sections at http://tromey.com/blog/?cat=17 7. Pretty printing, part 1 8. Pretty printing, Part 2 The gdb wiki http://sourceware.org/gdb/wiki/STLSupport explains how to setup C++ STL pretty printers to reproduce Tom example for printing a C++ string. The next gdb 7.3 release provides a gdb.printing python package to be used in building custom pretty printers. > I guess another advantage of automatic pointer dereferencing is that > gdb/pyclewn could tell you if a pointer points to unallocated memory > when hovering it. > Right, this is not correctly implemented right now.

Might be hard to implement though =) That would be great, but yes, difficult to implement with vim netbeans interface. -- Xavier Les Chemins de Lokoti: http://lokoti.alwaysdata.net ------------------------------------------------------------------------------ Simplify data backup and recovery for your virtual environment with vRanger.
