PikaDebug debugger
The PikaDebug debugger module provides features such as breakpoint debugging.
class Debuger():
The Debuger class provides the debugger function. By creating an object of the Debuger class, a debugger can be created.
Debuger class methods
class Debuger:
def __init__(self):
pass
def set_trace(self):
pass
The __init__() method is the method executed when the object is created, and the user does not need to know about it. The set_trace() method can place a breakpoint in the code. When the code execution reaches the breakpoint, it will stop and open the (pika-debug) terminal. The user can enter commands in the terminal (c : continue running, q : to end debugging), or a python interactive call ( printf(i), i = 10).
Example:
import PikaDebug
pkdb = PikaDebug.Debuger()
i = 0
while i < 10:
i = i + 1
print('i:' + str(i))
# set a breakpoint here
pkdb.set_trace()
Command example:
n: (next) continue to run to the next breakpoint.
q: (quit) to exit debug mode and continue running.
p: (print) print variable, p i means print variable i.
Interactive run: Directly execute interactive commands, such as print(i), i = 2, etc.
# Debug logging example
i : 1
(pika-debug) n
i : 2
(pika-debug) n
i : 3
(pika-debug) n
i : 4
(pika-debug) p i

(pika-debug) print(i)

(pika-debug) i = 2
(pika-debug) n
