# Parsing
The parsing functionality is for saving and loading from a custom file format.
The BNF for the custom file format is below.
Terminals are surrounded by `**` to the left and right. (rule)+ means "1 o more".
```
int ::= (0-9)+
item ::= **{** int int int int int int int int **}**
grid ::= int int **{** (item)+ **}**
```
The first two `int`s in the grid `int int **{** (item)+ **}**` always follow the order: `canvasWidth canvasHeight`.
The large number of `int`s in the `item` always follows the order: `x y ex ey r g b a`.
