windows VScode gdb 无法查看stl vector,set等值(1)

本文介绍了如何解决在Windows环境下使用VSCode的GDB调试时无法查看STL容器如vector和set内容的问题。通过创建.gdbinit配置文件并将其放置在用户目录下,同时设置HOME环境变量,可以实现使用-exec pvector命令来查看vector的值。该方法适用于需要在VSCode调试过程中查看STL容器详细信息的开发者。

#   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
#
#   The following STL containers are currently supported:
#
#       std::vector<T> -- via pvector command
#       std::list<T> -- via plist or plist_member command
#       std::map<T,T> -- via pmap or pmap_member command
#       std::multimap<T,T> -- via pmap or pmap_member command
#       std::set<T> -- via pset command
#       std::multiset<T> -- via pset command
#       std::deque<T> -- via pdequeue command
#       std::stack<T> -- via pstack command
#       std::queue<T> -- via pqueue command
#       std::priority_queue<T> -- via ppqueue command
#       std::bitset<n> -- via pbitset command
#       std::string -- via pstring command
#       std::widestring -- via pwstring command
#
#   The end of this file contains (optional) C++ beautifiers
#   Make sure your debugger supports $argc

document pvector
	Prints std::vector<T> information.
	Syntax: pvector <vector> <idx1> <idx2>
	Note: idx, idx1 and idx2 must be in acceptable range [0..<vector>.size()-1].
	Examples:
	pvector v - Prints vector content, size, capacity and T typedef
	pvector v 0 - Prints element[idx] from vector
	pvector v 1 2 - Prints elements in range [idx1..idx2] from vector
