+# OpenBuggerNotebook
+
+https://github.com/furlat/OpenBugger/blob/main/README.md is a Python package
+that allows you to inject syntax and logic errors into your code. This can be
+useful for testing the robustness of your code or for creating test cases for
+debugging exercises or for training an assistant to debug code.
+
+The Python notebook openbugger_example.ipynb does the following:
+
+1. Imports the necessary libraries to install OpenBugger in the notebookdirecory
+   (os and subprocess).
+2. Defines a function, install_openbugger, which clones the OpenBugger
+   repository from GitHub and installs it using pip.
+3. Calls the install_openbugger function to install OpenBugger.
+4. Imports the SyntaxBug and LogicBug classes from the syntax_injector and
+   logic_injector modules, respectively.
+5. Creates an instance of the SyntaxBug class and assigns it to the syntax_bug
+   variable.
+6. Defines three scripts: a simple script, a medium script, and a hard script.
+7. Calls the inject method on the simple script, passing in the string "easy" as
+   the second argument and the integer 1 as the third argument. This will inject
+   easy syntax errors into the script. The *item *item modified script, a list
+   of the injected errors, and the number of errors injected are returned and
+   assigned to variables.
+8. Prints the original and modified versions of the simple script, as well as
+   the list of injected errors and the number of errors injected. 10 Repeats
+   steps 7 and 8 for the medium and hard scripts, but with the "medium" and
+   "hard" injection methods and different numbers of errors to inject.
+
+General Usage To use OpenBugger, import the SintaxBug or LogicBug classes from
+the openbugger module and use them to inject a bug with a call to the inject().
+The injector will return the modified script with the injected bug.
+
+```
+from syntax.syntax_injector import SyntaxInjector, SyntaxBug
+
+syntax_bug = SyntaxBug()
+
+
+
+# Simple script
+simple_script = """
+def greet(name):
+    print("Hello, " + name)
+
+greet("Bob")
+"""
+
+print(simple_script)
+```
+
+The simple script can be modified using the "easy" injection method because it
+only contains simple syntax and does not have any nested code blocks. This means
+that there are fewer characters (e.g. quotes, brackets, braces, parenthesis)
+that could be the target of syntax errors, and the "easy" injection method,
+which only injects errors that involve replacing or removing a single character,
+is sufficient to modify the script.
+
+```
+# Inject easy syntax errors into the simple script
+
+modified_simple_script, errors, counter = syntax_bug.inject(simple_script, "easy", 1)
+print("Modified version Easy",errors,counter)
+print(modified_simple_script)
+```
+
+Or for higher severity and logic error by directly transforming a Python class
+into text
+
+```
+import inspect
+import random
+from logic.logic_injector import LogicBug
+
+
+# Medium example script
+def medium_script():
+    # Choose a random integer and assign it to a variable
+    num = random.randint(0, 10)
+
+    # Use a loop to print all numbers from 0 to the chosen integer
+    for i in range(num):
+        print(i)
+
+# create an instance of the LogicBug class
+logic_bug = LogicBug()
+# get the source code of the medium_script function as a string
+medium_script_str = inspect.getsource(medium_script)
+print("Medium",medium_script_str)
+# inject a logic error into the medium_script function
+modified_medium_script, error, counter = logic_bug.inject(medium_script_str,"medium",num_errors=3)
+```
