# 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
...
```
