## MiniScript Language
|
|
|
|
MiniScript is a simple embeddable, functional, dynamic-typed, bytecode-interpreted, scripting language written in C. It uses the [mark-and-sweep](https://en.wikipedia.org/wiki/Tracing_garbage_collection) method for garbage collection. MiniScript is is syntactically similar to Ruby. The frontend and expression parsing techniques were written using [Wren Language](https://wren.io/) and their wonderful book [craftinginterpreters](http://www.craftinginterpreters.com/) as a reference.

### What MiniScript looks like
|
|
|
|
```ruby
|
|
|
|
## Find and return the maximum value in the [list].
|
|
def get_max(list)
|
|
ret = list[0]
|
|
for i in 1..list.length
|
|
ret = max(ret, list[i])
|
|
end
|
|
return ret
|
|
end
|
|
|
|
## Return a list where each element returns true with function [fn] and
|
|
## belongs to [list].
|
|
def filter(list, fn)
|
|
ret = []
|
|
for elem in list
|
|
if fn(elem)
|
|
list_append(ret, elem)
|
|
end
|
|
end
|
|
return ret
|
|
end
|
|
|
|
list = [42, null, 3.14, "String", 0..10, ['hello']]
|
|
nums = filter(list, is_num)
|
|
print(get_max(nums))
|
|
|
|
```
