Module Overview

io

Input and output operations including console I/O, streams, and buffered reading.

import io

action main()
    @io#write("Enter your name: ")
    @name = @io#read_line()
    @io#write("Hello, " + @name)
fin action.

fs

File system operations for reading, writing, and manipulating files and directories.

import fs

action main()
    @content = @fs#read_file("config.toml")
    @fs#write_file("output.txt", @content)
fin action.

math

Mathematical functions, constants, and random number generation.

import math

action main()
    @pi = @math#PI
    @sqrt = @math#sqrt(144)  @// 12.0
    @random = @math#random(1, 100)
fin action.

strings

Advanced string manipulation beyond built-in string methods.

import strings

action main()
    @result = @strings#trim("  hello  ")
    @split = @strings#split("a,b,c", ",")
fin action.

collections

Advanced data structures like linked lists, queues, and trees.

import collections

action main()
    @queue = @collections#Queue<Int>::new()
    @queue#push(1)
    @queue#push(2)
    @value = @queue#pop()
fin action.

json

Parse and generate JSON data.

import json

action main()
    @data = @json#parse('{"name": "Alice", "age": 30}')
    @json_string = @json#stringify(@data)
fin action.

http

Build HTTP servers and make HTTP requests.

import http

action main()
    @server = @http#Server::new()
    @server#get("/", fn(@req) => "Hello, World!")
    @server#listen(8080)
fin action.

time

Work with dates, times, durations, and intervals.

import time

action main()
    @now = @time#now()
    @formatted = @time#format(@now, "YYYY-MM-DD")
    @time#sleep(seconds(1))
fin action.

process

Access environment variables, command-line arguments, and manage processes.

import process

action main()
    @args = @process#args()
    @env = @process#env("HOME")
    @process#exit(0)
fin action.
