# Refactoring Document

## Types of functions
- C function wrap
- getter
- setter
- initializer

### C function wrap
```
static mrb_value
mrb_#{function_name}(mrb_state* mrb, mrb_value self) {
	
	#{initialize vars}
	
	#{unwrap kwarg/arg}
	
	#{kwargs.each do assignment} <-- this will need to unwrap structs
	^ also need to check if a default exists 
	
	#{call method}
	
	#{wrap return struct} <-- only if return is new struct
	#{return}
}
```

### Getter
```
mrb_#{struct_name}_get_#{var}(mrb_state* mrb, mrb_value self) {

#{unwrap struct}

#{return value} <-- may need to wrap value if its a struct
}
```

### Setter
```
mrb_#{struct_name}_set_#{var}(mrb_state* mrb, mrb_value self) {
#{initialize var}
#{get arg}
#{unwrap struct}
#{set value}
#{return the value from the struct}
}
```

### Initializer
```
mrb_#{struct_name}_initialize(mrb_state* mrb, mrb_value self) {
#{initialize var}
#{unwrap kwarg/arg}

#{kwargs.each do assignment} <-- this will need to unwrap structs
^ also need to check if a default exists 

#{initialize as mrb object}

return self
}
```
