This commit adds a simple side panel to allow users to interact with the
application. The side panel allows the user to:
- Generate and regenerate mazes
- Choose between the searching algorithms
- Choose whether or not to add randomness to the algorithm
- Run and re-run the simulation
Create a separate class to represent the solver of the maze.
Additional search algorithms will be implemented here.
Additional changes:
- Add public methods to mark cells as visited and to get results of
the visits.
- Renamed MazeDirections to MazeDirection.
- Renamed _num_cell_rows to _height.
- Renamed _num_cells_per_row to _width.
- Created a dedicated method to configure a cell's walls in the Maze
class.
- created a dedicated public method to draw a path between two cells in
the Maze class.
- Fixed the issue where during the reconfiguration of the walls of a
cell, those that weren't being reconfigured were reset to True
regardless of their previous configuration.
- During testing, don't run the _break_walls_r method because it will
run into the RecursionError exception.
- Simplify the code for drawing cells and fix the redrawing wasn't
applied properly.
Main feature:
- Added functionality to randomly generate a maze before the solver
solves it.
Fixes:
- Add a public method in the Cell class called wall_exists() that
returns true if a given cell wall exists (false otherwise).
Refactors:
- Added an enum type called CellWallLabel for labelling the four cell
walls.
- Added a draw() function in the CellWall class to reduce repeated code.
- Move the custom exceptions to errors.py
Tests:
- Add tests for the custom exceptions.
CI:
- Added a workflow for Forgejo Actions.
- Raise CellInvalidError when attempting to specify the wrong corners of
the cell when creating it. The x and y values should always represent
the top left and bottom right corners of the cell.
- Raise CellTooSmallError when attempting to specify a cell which is too
small to correctly draw its central point.
- Add an entrance and exit to the maze. The entrance will always
be on the top left and the exit will always be on the bottom
right.
- Add a simple GitHub actions workflow to run the Python tests.
Optionally pass in the reference of the Window to the Maze and
Cell classes, and only draw the graphics if the reference exists.
Use a single underscore instead of the double underscore for private
Class members.
