Hello,

	some days ago, I send here a (crap and buggy) patch that allows GDB to
display STL containers. I know that this patch was too intrusive and
dependent of the STL version.

	Today, I wrote another patch that allows me to load plugin into GDB
that are called in particular situations, like displaying the content of
a variable of a particular type, or creating varobjects in MI
interpreter. It is used to format any kind of datas as I want it to be
displayed.

	I submit a new version of my STL container viewer, but this time as a
plugin. It handles STL container access as it was a classic C array, and
answers queries like 'sizeof'... It also support MI interpreter, so that
GDB could be used with frontend, still displaying data correctly. I
tried it with Eclipse/CDT, KDevelop, KDBG, Nemiver and Insight/GDB. All
works well !

	In order to compile the plugin, you'll have to modify the Makefile and
set the correct value for GDB_SOURCES variable.

	After that, launch a GDB session, and execute the command

(gdb) loadplugin /path/to/plugin/stl.so

	A typical session could look like that

(gdb) b 122
Breakpoint 1 at 0x8049602: file main.cpp, line 122.
(gdb) r
Starting program: /home/bsr/sources/stl/a.out 

Breakpoint 1, main () at main.cpp:122
122	    return 0;
(gdb) whatis m
type = std::map<const char*,int,std::less<const
char*>,std::allocator<std::pair<const char* const, int> > >
(gdb) p m
$1 = {
  {
    0x8051ec6 "un",
    1
  }, 
  {
    0x8051ec9 "deux",
    2
  }, 
  {
    0x8051ece "trois",
    3
  }
}

(gdb) p m[2]
$2 = {
  first = 0x8051ece "trois", 
  second = 3
}
(gdb) p sizeof(m)
$3 = 12
(gdb) stlsizeof 1
sizeof operator on STL containers will print the number of elements.
(gdb) p sizeof(m)
$4 = 3
(gdb) ...



	You could simply put the command into your ".gdbinit" to allow
frontends to use STL data formatter.

PS: I know that there is a Python scripting patch in progress. Mine is
only a small patch to allows people to use this feature today, waiting a
cleaner engine !
