UselessTranslator

Useless translator for useless language. This is course project. Language use for system of manage robot in cell maze. Maze is a square. Robot can move to neighbor, cell if it is empty.

Lanuage description

• N - is variable number without repetition.
• I - index of array (int)
• ID -> .N | ,N | $N ?! maybe arrays
• one line - one statement

1. Literals

• Integer [0-9]{1,}
• Boolean T|F

2. Variables

• Integer ,N
• Bool .N
• Procedures $N
• Labels ~N
• Interer array
  • ,N: -> int aN[0];
  • ,N:I1 -> int aN[I1];
  • ,N:I1-I2 -> int aN[I1][I2];
• Bool array
  • .N: -> bool aN[0];
  • .N:I1 -> bool aN[I1];
  • .N:I1-I2 -> bool aN[I1][I2];
• Procedures array
  • $N: -> func aN[0];
  • $N:I1 -> func aN[I1];
  • $N:I1-I2 -> func aN[I1][I2];

3. Operators

• Arithmetical (int)
  • increment ,#N -> aN += 1
  • decrement ,*N -> aN -= 1
• Logic (bool)
  • logical nor: .#(logic exp) !?
• Assigment <-
• Comparison <exp> eq <const>. Three types: logic, int, proc
• Cycles (<logic exp>)<cycle operator>{statements} ?! Note: I dont know what should I use how a cycle operator
• Conditions [<logic exp>] please ~N ?! need to know, can I do so?
  if logic exp is true go to label
• pass operator np. This is python pass
• binding operator ID @ $N. bind ID to procedure with the following features:
  • binding many id to many procedure
  • recursive binding is forbidden (return F)
  • on handling binded ID: at first call proc, after that return ID value
• unbinding operator ID % $N (return T)

4. Operators for manage robot

• move robot to one cell on selected direction mf | mb | mr | ml, return T if robot can do it, else F
• teleport robot to another random cell tp, robot has limited quantity try use tp, after use this command robot dont know his position.
