Creating a Debugging Window with PyQt

This is still part of my Chat Application Project. Trying to enhanced my IDE to include a debugging window. 

Debugging is a crucial aspect of software development and it requires a lot of attention and effort to ensure that the code is free of bugs and runs smoothly. Debugging can be done in a variety of ways, but one of the most popular methods is to use a debugger window. A debugger window provides an interactive interface for the developer to monitor and control the execution of the program.

One approach to creating a debugger window is by using PyQt, a popular GUI framework for Python. PyQt provides a way to embed a terminal window into a PyQt application, which can be used as a debugging window. By doing this, developers can run their code and view the output directly in the PyQt application, making it easier to monitor and debug their code.

The PyQt debugger window consists of a command execution button, a QLineEdit to enter the OS command, and a QTextEdit to view the result of the command. The program uses the subprocess library in Python to run the code, which is entered in the QLineEdit, and the output is displayed in the QTextEdit.

One of the advantages of using PyQt to create a debugger window is that it provides a convenient and interactive way for developers to run their code and view the output. With the debugger window embedded in the PyQt application, developers can quickly view and debug their code without having to switch back and forth between different windows or tools.

In conclusion, creating a debugger window with PyQt is a great approach for software development. It provides an interactive and convenient way for developers to monitor and control the execution of their code, making the debugging process much easier and efficient. The ability to embed a terminal window in a PyQt application is a powerful feature that can greatly enhance the debugging process and make it easier for developers to identify and fix any bugs in their code.. 

Here's my planned logic:

• Create a function that will allow a programmer to insert a breakpoint
• If no breakpoint is inserted, debugging starts on the first executable line
• The debug window should embed the cmd terminal(this is dificult to implement)
• Debug window should display the code and the current line where it stopped
• To pause a program, I will insert an invisible input command at each line but when a breakpoint is specified autmatically will remove the input command before the breakpoint is reached
• User will enter the variable name at the input terminal to display the current value

So far, I have succeeded embedding the cmd terminal into a PyQt and allows me to interact with it. Here the source code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40

import sys from PyQt5.QtCore import QProcess, QTextStream from PyQt5.QtWidgets import QApplication, QMainWindow, QTextEdit, QLineEdit, QVBoxLayout, QHBoxLayout, QWidget, QPushButton class MainWindow(QMainWindow): def __init__(self): super().__init__() self.process = QProcess(self) self.output = QTextEdit(self) self.input = QLineEdit(self) self.run_command_button = QPushButton("Run Command", self) layout = QVBoxLayout() input_layout = QHBoxLayout() input_layout.addWidget(self.input) input_layout.addWidget(self.run_command_button) layout.addLayout(input_layout) layout.addWidget(self.output) central_widget = QWidget(self) central_widget.setLayout(layout) self.setCentralWidget(central_widget) self.process.readyReadStandardOutput.connect(self.read_output) self.run_command_button.clicked.connect(self.run_command) self.process.start("cmd.exe") def read_output(self): stream = QTextStream(self.process) self.output.append(stream.readAll()) def run_command(self): command = self.input.text() + "\n" self.process.write(command.encode()) if __name__ == '__main__': app = QApplication(sys.argv) window = MainWindow() window.show() sys.exit(app.exec_())

I tried to test it if I can interact with it using the program below and to run it I just enter into the qlineedit textbox the following: "python prog_name.py" and it ask my name and enter my name on the same textbox and the result is the following:

Here is the code of the example program:

1 2 3

print("Enter your name: \n") x = input() print(x)

As a final conclusion, I think I am on the right track. I am optimistic that the debugger window will be up and running soon. Also, auto indentation is already working but not yet uploaded to my github page. The implementation is surprisingly very simple. I did not have to use machine learning.
