Dict

A dict is a key - value string pair storage. It can be constructed using the curly brace syntax:

var data =
{
  "hello" => "world"
  "lol" => "wtf"
} 

Pairs can optionally be separated by a semicolon when you need to write the dict in one line (for example, when passing it to a function).

Keys can be defined by any of the following:

• string literals
• integers
• floats
• identifiers
• expressions in parens

Please note, that identifier keys are not resolved, and are rather used as "bare strings". Consider the following code snippet:

var foo = "bar"
var dict1 = {  foo => "hello" } // same as { "foo" => "hello" }
var dict2 = { (foo) => "hello" } // interpreted as expression! { "bar" => "hello"} 

Values can either be strings, or any other object for which a to_s convertor is defined.

It should also be noted that the dict type contains both keys and values as strings. Using ints, floats and identifiers as keys is merely a syntactic sugar, and values will need to be converted from strings to desired type manually.

Operators

The following operators can be applied:

• Addition: create a mix of two dicts
• Subtraction: create a dict that contains all items from left dict except for items from right one

Methods

The type contains the following methods:

• int size: gets the number of key-value pairs in the dict
• string get(string key): return a value by key
• void set(string key, string value): set a value
• void unset(string key): remove a given item
• bool has(string key): checks if the dict contains a key
• bool has_value(string value): checks if the dict contains a value
• string[] keys: gets an array of keys
• string[] values: gets an array of values
