Typedefs

A type definition is a .d.lis file that describes a Go package in Lisette syntax.

func Atoi(s string) (int, error)
Go function signature

strconv.go

pub fn Atoi(s: string) -> Result<int, error>
Lisette equivalent

strconv.d.lis

Typedefs are written by the compiler, never by hand.

• Go stdlib typedefs are built into the compiler.
• For third-party dependencies, lis add writes typedefs to target/.lisette/typedefs in your project.

To inspect a typedef in your IDE, use Go to Definition on any imported Go symbol.

Type equivalents

Typedefs describe many Go types identically in Lisette:

Go	Lisette
string	string
bool	bool
error interface	error interface
int, int8, int16, etc.	int, int8, int16, etc.
uint, uint8, uint16, etc.	uint, uint8, uint16, etc.
float32, float64	float32, float64
complex64, complex128	complex64, complex128

Other Go types are described differently:

Go	Lisette
(T, error)	Result<T, error>
error as the only return	Result<(), error>
(T, bool)	Option<T> or (T, bool)
*T	Ref<T> or Option<Ref<T>>
any, interface{}	Unknown
[]T	Slice<T>
[N]T	Array<T, N>
map[K]V	Map<K, V>
...T	VarArgs<T>
chan T	Channel<T>
type X int64	pub struct X(int64)
