当我set logging on在 gdb 中使用时，日志文件的输出格式与我在终端屏幕上看到的格式不同。日志文件不是很可读。如何以可读格式获取日志文件？
输出到屏幕很好：
(gdb) p foo
$1 = {
static npos = 18446744073709551615,
_M_dataplus = {
<std::allocator<char>> = {
<__gnu_cxx::new_allocator<char>> = {<No data fields>}, <No data fields>},
members of std::basic_string<char,std::char_traits<char>,std::allocator<char> >::_Alloc_hider:
_M_p = 0x601028 "Hello World!\n"
}
}
输出到日志文件不是很可读：
