An opinionated lisp implementation developed in the most intuitive way I could come up with.
|
|
|
|
## Features
|
|
|
|
### Lists with a function as the **first element** are evaluated when needed
|
|
|
|
```lisp
|
|
(print (add 1 2)) ; => 3
|
|
(print (1 2 3)) ; => (1 2 3)
|
|
```
|
|
|
|
### Quoted lists are **not evaluated**
|
|
|
|
```lisp
|
|
(print '(add 1 2)) ; => '(<function add> 1 2)
|
|
```
|
|
|
|
### Elements within quoted lists can be unquoted
|
|
|
|
```lisp
|
|
(print
|
|
'(add
|
|
1 ,(sub 3 1)
|
|
)
|
|
) ; => '(<function add> 1 2)
|
|
```
|
|
|
|
### Maps can be indexed with .
|
|
|
|
```lisp
|
|
; In this example, ball_pos is a map
|
|
(print ball_pos.x ball_pos.y)
|
|
|
|
; This is just syntax sugar for
|
|
(get ball_pos "x")
|
|
```
|
|
|
|
### Functions can be defined and called like so
|
|
|
|
```lisp
|
|
(fn hello(name) (
|
|
(print (concat "Hello, " name "!"))
|
|
))
|
|
|
|
(hello "Joe") ; => "Hello, Joe!"
|
|
|
|
|
|
; Anonymous function creation
|
|
(
|
|
(fn(x) (print x))
|
|
15
|
|
) ; => 15
|
|
``` |
