PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
General	Improve assertion error messaging The assertion message could be misleading if the graph is of an unexpected type. Consider using a more descriptive error message that includes the type of the provided graph to aid in debugging. cicd_graph/cicd_graph.py [149-150] -assert (isinstance(graph, graphParallel) or isinstance(graph, graphSimple)), f"Serial graph may only contain simple or parallel sub-graphs" +assert (isinstance(graph, graphParallel) or isinstance(graph, graphSimple)), f"Serial graph may only contain simple or parallel sub-graphs, got {type(graph).__name__}" Suggestion importance[1-10]: 7 __ Why: The suggestion enhances the error message for better debugging by including the type of the provided graph. This improves maintainability and clarity in error handling.	Medium
	Validate polygon points before drawing The create_polygon method is being called with a list of points that may not form a valid polygon if the points are not unique or are incorrectly defined. Ensure that the points list contains valid coordinates to avoid rendering issues. Consider adding validation for the points before drawing. cicd_graph/cicd_graph.py [48-49] -self.canvas.create_polygon(points, fill=color, smooth=True, outline="black", width=2) +if len(set(points)) >= 3: # Ensure at least 3 unique points for a polygon + self.canvas.create_polygon(points, fill=color, smooth=True, outline="black", width=2) Suggestion importance[1-10]: 6 __ Why: The suggestion addresses potential rendering issues by ensuring that the points used to create a polygon are valid. However, it does not address the underlying logic of how points are defined.	Low
	Clarify control point condition check The condition checks for through_x and through_y being -1, which may not be clear in intent. Consider using a more descriptive constant or enum to represent the absence of a control point for better readability and maintainability. cicd_graph/cicd_graph.py [73-74] -if (through_x == -1 or through_y == -1): +if (not self.has_control_point(through_x, through_y)): # Define a method to check for control points Suggestion importance[1-10]: 5 __ Why: While the suggestion aims to improve readability by using a method to check for control points, it introduces a new method that is not defined in the provided code, which could lead to confusion.	Low
	Ensure distinct arrowhead coordinates The arrowhead drawing logic could lead to overlapping lines if the coordinates are not calculated correctly. Ensure that the coordinates for the arrowhead are distinct and do not overlap with the line being drawn. cicd_graph/cicd_graph.py [121-122] -self.canvas.create_line(x2 - 10, y2 - 10, x2, y2, x2 - 10, y2 + 10, fill="black", width = 3) +arrow_head_coords = [(x2 - 10, y2 - 10), (x2, y2), (x2 - 10, y2 + 10)] +self.canvas.create_line(x2 - 10, y2 - 10, x2, y2, x2 - 10, y2 + 10, fill="black", width=3) Suggestion importance[1-10]: 4 __ Why: The suggestion points out a potential issue with overlapping lines in the arrowhead drawing logic. However, the proposed change does not alter the logic and merely reassigns coordinates without addressing the underlying calculation.	Low
