binshengliu / .gdbinit
Created February 2, 2012 06:11
.gdbinit to print stl containers. see http://www.yolinux.com/TUTORIALS/GDB-Commands.html
#
# STL GDB evaluators/views/utilities - 1.03
#
# The new GDB commands:
# are entirely non instrumental
# do not depend on any "inline"(s) - e.g. size(), [], etc
# are extremely tolerant to debugger settings
#
# This file should be "included" in .gdbinit as following:
# source stl-views.gdb or just paste it into your .gdbinit file
