Running the Program

Main class: slogo.Main.java, mark /resources as resources root

Data files needed: Everything under resources/ and slogo/resources/

Features implemented:

• Basic commands for moving the turtle, math operations, boolean operations, turtle queries, variables, and control structures
• User defined commands
• Error catching for parsing issues
• Seeing results of turtle executing commands
• Set background color, pen color, pen thickness, turtle image from UI and from commands
• See current variables, user-defined commands, color palette, current turtle states, and history in different tabs
• Choose language to operate in
• Changing language can happen dynamically and will change history and user-defined commands as well
• Accessing a help page
• Clicking to execute commands
• Clicking to load history
• Moving the turtles graphically
• Change pen properties graphically
• Recognize and correctly perform multiple turtle commands
• Recognize and correctly perform display commands
• Recognize and correctly perform commands with unlimited parameters

Notes/Assumptions

Assumptions or Simplifications:

• With multiple turtles, if a command is run that involves parsing again, such as Repeat, the internal parsing command will be run on each turtle a number of times equal to number of active turtles.
• Assume no issues with properties files
• Always need at least one turtle active

Interesting data files:

Known Bugs:

• Clear screen command does not work clear since it is overridden by parser passing immutable turtles

Extra credit:

• Dark mode
• Slider for changing GUI turtle movement
