# Ginger
|
||||
|
||||
A lisp-like language built on the go programming language. The ideas are still a
|
||||
work-in-progress, and this repo is where I'm jotting down my notes.
|
||||
|
||||
# Walkthrough
|
||||
|
||||
This is a number which evalutates to 5:
|
||||
|
||||
```
|
||||
5
|
||||
```
|
||||
|
||||
This is a string, as it contains no whitespace:
|
||||
|
||||
```
|
||||
ImJustAString
|
||||
```
|
||||
|
||||
This is also a string, it can contain anything:
|
||||
|
||||
```
|
||||
"! I'm the king of the world !"
|
||||
```
|
||||
|
||||
This is a list. It evaluates to a linked-list of its elements (not lisp-like!):
|
||||
|
||||
```
|
||||
(a b c d)
|
||||
```
|
||||
|
||||
This is a string:
|
||||
|
||||
```
|
||||
+
|
||||
```
|
||||
|
||||
This is a string being evaluated, it will return a function:
|
||||
|
||||
```
|
||||
:+
|
||||
```
|
||||
|
||||
This is a list, with a string and two numbers:
|
||||
|
||||
```
|
||||
(+ 1 2)
|
||||
```
|
||||
|
||||
This is a list, with a function and two numbers:
|
||||
|
||||
```
|
||||
(:+ 1 2)
|
||||
```
|
||||
|
||||
This is a list being evalutated, the first item in the list must be a function:
|
||||
|
||||
```
|
||||
:(:+ 1 2)
|
||||
```
|
||||
|
||||
This is a list in a list:
|
||||
|
||||
```
|
||||
((a b) foo bar)
|
||||
```
|
||||
|
||||
This is an anonymous function, it takes in the arguments `a` and `b`, and
|
||||
returns their sum:
|
||||
|
||||
```
|
||||
#((a b)
|
||||
:(:+ :a :b))
|
||||
```
|
||||
|
||||
`map` takes in a function and a list, and calls the function on each item in the
|
||||
list. The following will return `(1 2 3)`:
|
||||
|
||||
```
|
||||
:(:map ; This is a comment, it's ignored
|
||||
#((a) (:+ :a 1)) ; <- Increment function
|
||||
(0 1 2))
|
||||
```
|
||||
|
||||
`name` names a value. After the following call, `:ted` will always evalutate to
|
||||
`5`:
|
||||
|
||||
```
|
||||
:(:name ted 5)
|
||||
```
|
||||
|
||||
You can name any value, including functions:
|
||||
|
||||
```
|
||||
:(:name increment #((a) :(:+ a 1)))
|
||||
```
|
||||
|
||||
Now the `map` example above can be simplified down to:
|
||||
|
||||
```
|
||||
:(:map :increment (0 1 2))
|
||||
```
