68 "You may enter either one or more lines of Python, including function \

70the code executes. Single line watchpoint commands will be interpreted 'as is' \
71when the watchpoint is hit. Multiple lines of Python will be wrapped in a \
72generated function, and a call to the function will be attached to the watchpoint."
73 R"(
74
75This auto-generated function is passed in three arguments:

77 frame: an lldb.SBFrame object for the frame which hit the watchpoint.
78
79 wp: the watchpoint that was hit.

94 "The arguments are the same as the arguments passed to generated functions as \
95described above. Note that the global variable 'lldb.frame' will NOT be updated when \
96this function is called, so be sure to use the 'frame' argument. The 'frame' argument \
97can get you to the thread via frame.GetThread(), the thread can get you to the \
98process via thread.GetProcess(), and the process can get you back to the target \
99via process.GetTarget()."
