13. Interpreter Abstract Syntax Tree (AST) Source Code Tokens Evaluation Lexical Analysis Parsing

14. Chop up text into pieces which are more meaningful to the parser These pieces are called tokens Lexical Analysis

15. Lexing let answer = 40 + 2;

16. Lexing let answer = 40 + 2;

17. Lexing let answer = 40 + 2;

18. Lexing LET let answer = 40 + 2;

19. Lexing LET let answer = 40 + 2;

20. Lexing LET let answer = 40 + 2;

21. Lexing LET IDENTIFIER("answer") let answer = 40 + 2;

22. Lexing LET IDENTIFIER("answer") let answer = 40 + 2;

23. Lexing LET IDENTIFIER("answer") EQUAL_SIGN let answer = 40 + 2;

24. Lexing LET IDENTIFIER("answer") EQUAL_SIGN let answer = 40 + 2;

25. Lexing LET IDENTIFIER("answer") EQUAL_SIGN let answer = 40 + 2;

26. Lexing LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) let answer = 40 + 2;

27. Lexing LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) let answer = 40 + 2;

28. Lexing LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN let answer = 40 + 2;

29. Lexing LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN let answer = 40 + 2;

30. Lexing LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) let answer = 40 + 2;

31. Lexing LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) let answer = 40 + 2;

32. Lexing LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON let answer = 40 + 2;

33. Lexing LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON let answer = 40 + 2;

34. Lexing LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF let answer = 40 + 2;

35. Lexing LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF let answer = 40 + 2;

36. Parser takes input data and builds a data structure giving a structural representation of the input, checking for correct syntax in the process. Parsing Wikipedia

37. Parsing let answer = 40 + 2;

38. Parsing let answer = 40 + 2; LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF

39. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF

40. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF LetStatement Name Value

41. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF LetStatement Name Value Identifier Value

42. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF LetStatement Name Value Identifier Value : "answer"

43. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF LetStatement Name Value Identifier Value : "answer"

44. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF LetStatement Name Value Identifier Value : "answer" IntegerLiteral Value: 40

45. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF LetStatement Name Value InfixExpression LHS RHS Identifier Value : "answer" IntegerLiteral Value: 40

46. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF LetStatement Name Value InfixExpression LHS RHS Identifier Value : "answer" IntegerLiteral Value: 40

47. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF LetStatement Name Value InfixExpression LHS RHS Identifier Value : "answer" IntegerLiteral IntegerLiteral Value: 40 Value: 2

48. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF LetStatement Name Value InfixExpression LHS RHS Identifier Value : "answer" IntegerLiteral IntegerLiteral Value: 40 Value: 2

49. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF LetStatement Name Value InfixExpression LHS RHS Identifier Value : "answer" IntegerLiteral IntegerLiteral Value: 40 Value: 2

50. Parsing let answer = 40 + 2; Program Statements[] LET IDENTIFIER("answer") EQUAL_SIGN INTEGER(40) PLUS_SIGN INTEGER(2) SEMICOLON EOF LetStatement Name Value InfixExpression LHS RHS Identifier Value : "answer" IntegerLiteral IntegerLiteral Value: 40 Value: 2
