webkit关于gdb的wiki:http://trac.webkit.org/wiki/GDB
它是自带了gdb和lldb的python脚本的,路径分别在
webkit workingcopy/Tools/gdb/webkit.py 直接看脚本内容http://trac.webkit.org/browser/trunk/Tools/gdb/webkit.py
webkit workingcopy/Tools/lldb/lldb_webkit.py 直接看脚本内容http://trac.webkit.org/browser/trunk/Tools/lldb/lldb_webkit.py
配置lldb初始化时加载python脚本:
1. 当然是checkout出lldb_webkit.py这个文件了,也可直接下载http://trac.webkit.org/export/147046/trunk/Tools/lldb/lldb_webkit.py,放在什么地方都行,现举例是放在用户目录下, 即 ~/
2. 在用户目录下新建文件,命名为“.lldbinit”,注意前面有个点符号哦。
3. .lldbinit的内容为:
command script import ~/lldb_webkit.py
4. 如果已打开,重启xcode
从脚本内容看,支持查看:
xcode只有lldb支持了python,所以以下的截图都是lldb的。
这是测试代码:
Vector v;
v.append("hello");
v.append("world");
HashMap map;
map.set("h", "hello");
map.set("w", "world");
AtomicString as = "thanks";
这是xcode的可视化调试窗口的效果:
这是terminal的p功能:
