# Plastic
A Functional and OOP experimental scripting language.
Conceptually inspired by Lisp and Ruby, syntactically by the C family.
### Functions
Standard function declaration:
```javascript
hello := func(who)
{
print ('hello ' + who)
}
```
Or written as a lambda expression:
```javascript
hello := who => print ('hello ' + who)
```
Partial applications
```javascript
f := func(a,b,c)
{
print('abc '+a+' '+b+' '+c);
}
f(1)(2)(3);
//or
//partial application of the "for" function
repeat10 = for(i:= 0;i<10;i++)
//apply the last argument, the body
repeat10
{
print (i)
}
```
### Macros
Macros in plastic is not a separate concept, they are normal functions in which some of the arguments are passed as expressions rather than evaluated values.
```javascript
myMacro := func (someScalar, someExpression.ref)
{
repeat(someScalar)
{
someExpression()
}
}
```
### Expressions
In Plastic, everything is an expression.
### Assignment
* `:=` assigns a value to a name in the current lexical scope.
* `=` assigns/updates the value in the scope it was declared
### Pattern matching
```javascript
(:dostuff,1,foo,bar) = (:dostuff,1,"hello","plastic")
```
`foo` is now "hello" and `bar` = "plastic"
### Classes
```javascript
Person := class (firstName,lastName)
{
sayHello := func ()
{
print ('Hello {0} {1}',firstName,lastName)
}
}
john := Person('John','Doe');
john.sayHello();
```
### Mixins
```javascript
BeepMixin := mixin
{
beep := func ()
{
print ('beep')
}
}
Person := class (firstName,lastName)
{
BeepMixin()
sayHello := func ()
{
print ('Hello {0} {1}',firstName,lastName)
}
}
john := Person('John','Doe');
john.beep();
```
### .NET Interop
```javascript
Console := using (System.Console);
Console.WriteLine('Name?');
name = Console.ReadLine();
Console.WriteLine('Hello {0}', name);
```
