Built-In Functions

* Only in Node runtimes

range

range: func (from: Number, to: ?Number, step: ?Number) Array[Number];

Same as Python's range function. Returns an array of numbers.

parse_num

parse_num: func (value: String) Number;

Parse floats or integers into numbers

import

import: func (path: String) Any;

Imports a module and returns the value. Slightly different behaviour between Node and browser runtimes:

• All imports must be declared in config file for browsers, which then get preloaded before runtime

help

help: func (value: Any) String;

Returns a string with information on the passed object.

print

print: func (*: Array[Any]) nil;

Calls the specified print function. Often just native console.log.

log

log: func (*: Array[Any]) nil;

Calls native console.log

delete

delete: func (symbol: String) nil;

Removes a symbol with the specified identifier.

path

__path__: func () String;

Returns The current path

symbols

__symbols__: func (recursive: ?Bool) Object;

Gets all symbols in the current scope. If recursive is true, then gets all symbols up the global context.

using

using: func (module: Any) nil;

Adds all symbols from object or namespace to the current scope.

throw

throw: func (name: String, detail: String) nil;

Throws an error of type name.

sleep

sleep: func (ms: Number, then: func (*: Array[Any]) Any) nil;

open *

open: func (path: String, encoding: ?String = 'utf-8') ({
    str: func () String,
    write: func (data: String) nil,
    append: func (data: String) nil
})};

Throws ImportError if the file doesn't exist.
