# Murphy Scanner, Parser and Interpreter of a simple Functional Programming Language ## Libraries No external libraries were used, you only need to have OCaml installed. ## Preview   ## Project setup (Linux) - #### Compile the file murphy.ml ### `ocamlc murphy.ml -o murphy.byte` - #### Write your code in a file name.txt and run it ### `./murphy.byte ./name.txt` ## Syntax - This language only works with Integer Numbers - IF, LET, IN, TEST, SUCCESS, FAIL, FUNC must be capitalized - Variables can't contain Capital Letters - Variables can't start with a Number ### Algebraic expressions ```javascript (exp) //brackets exp + exp //sum exp - exp //difference exp * exp //multiplication exp / exp //division ``` examples ```javascript 5 - 2 //3 0/0 //NaN 2/0 //PLUS_INFINITY 5 - 1/0 //MINUS_INFINITY 2/0 - 3/0 //NaN ... ``` ### Comparison ```javascript exp == exp exp < exp exp > exp ``` examples ```javascript 3 + 2 == 5 //TRUE 1 == 0 //FALSE 1 > 0 //TRUE 1 < 0 //FALSE ... ``` ### TEST statement ```javascript TEST exp [ == | < | > ] exp SUCCESS exp FAIL exp ``` examples ```javascript TEST (5 + 5) / 2 == 5 SUCCES 10 FAIL 1/0 ... ``` ### LET statement ```javascript LET ide = exp IN exp ``` examples ```javascript LET x = 1 IN LET y = 2 IN x*x + y*y ... ``` ### Function declaration ```javascript FUNC fname (ide1, ide2, ...) = exp IN exp ``` examples ```javascript FUNC sum (x, y) = x + y IN 5 + 5 ... ``` ### Function call ```javascript fname (exp1, exp2, ...) ``` examples ```javascript FUNC sum (x, y) = x + y IN TEST sum(2, 3) == 5 SUCCESS sum(2, 3) FAIL 0 ... ```
