Switching Files and Dictionaries Pre Release

Added:

• Switch statements
• Dictionaries
• Include statements
• Namespace type
• Attributes
• Lambdas
• Type built-in function

Modified:

• Less strict code block syntax
• Typed function arguments and return values
• Eqequals system for most types

Usage

# Switch statements

var fuel = 50
switch (var x as fuel) {
    when (x < 0) {
        print('Umm...')
    }
    when (x == 0) {
        print('Out of fuel')
    }
    when (x <= 10) {
        print('Almost out of fuel')
    }
    when (x <= 30) {
        print('Might want to fill up')
    }
    when (x <= 60) {
        print('Okay for now')
    }
    when (x <= 99) {
        print('Almost full')
    }
    when (x == 100) {
        print('Full')
    }
    else {
        print('Too much')
    }
}



# Dictionaries

var apples = {
    'a': 'apple',
    'b': 'babble',
    'c': 'cobble',
    'd': 'dabble',
    'f': 'fable',
    'g': 'gurgle',
    'h': 'hurdle'
}
print(
    apples['d']
)



# Include statements (Returns namespace type) & Attributes

var module = include('testmodule.peri')
print(str(
    module.add(1, 2)
))



# Lambdas

var add = lambda(a: int, b: int) -> int {a + b}
print(str(
    add(1, 2)
))



# Type built-in function

var string = type('hello')
print(str(
    string
))
print(
    string(10.0)
)



# Code block syntax is less strict

func (a: int, b: int) -> int {i_can_put_stuff_here('hello')
and_here('hello')}



# Function arguments and return values are typed

func(a: int, b: int) -> float {
#       ^^^     ^^^     ^^^^^
    return(float(a + b))
}
