Learn MSL - Macincode Scripting Language

MSL Basics

Hello World

Your first MSL program

log "Hello, World!"

Variables

Store and use data

var name = "Alice"
var age = 25
log "Name: " + name + ", Age: " + age

Comments

Document your code

// This is a single line comment
var x = 10  // Comment at end of line

Basic Operations

Math and string operations

var sum = 10 + 5
var message = "Hello" + " " + "World"
log sum
log message

Data Types & Structures

Objects

Store related data together

var user = {
    "name": "John",
    "age": 30,
    "email": "john@example.com"
}
log user.name

Arrays

Lists of data

var numbers = [1, 2, 3, 4, 5]
var names = ["Alice", "Bob", "Charlie"]
log numbers[0]  // First item
log names.length

Conditionals

Make decisions in code

var age = 18

if age >= 18
    log "Adult"
else
    log "Minor"

Loops

Repeat actions

var items = ["apple", "banana", "orange"]

for item in items
    log "Fruit: " + item

Built-in Functions

Database Operations

Work with databases easily

use "db"

// Insert data
query("INSERT INTO users VALUES (?, ?)", ("Alice", 25))

// Select data
var users = query("SELECT * FROM users")
log users

API Calls

Trigger external services

// POST request
trigger("https://api.example.com/users", {
    "name": "Alice",
    "email": "alice@example.com"
})

// GET request
var data = fetch("https://api.example.com/users")

AI Integration

Use AI in your applications

use "ai"

var prompt = "Summarize this text: " + user_input
var summary = ai(prompt)

var sentiment = analyze_sentiment("Great product!")
log sentiment.score

File Operations

Read and write files

// Read file
var content = read_file("data.txt")

// Write file
write_file("output.txt", "Hello World")

// Append to file
append_file("log.txt", "New entry")

Advanced Concepts

Parallel Tasks

Run multiple operations simultaneously

task "email" "trigger" "https://mail.api.com/send" {"to": "user@example.com"}
task "database" "query" "INSERT INTO logs VALUES (?)" ("Email sent")
task "ai" "ai" "Generate follow-up message"

var results = await "email" "database" "ai"
log "All tasks completed"

Error Handling

Handle errors gracefully

try
    var result = query("SELECT * FROM users")
    log result
catch error
    log "Database error: " + error.message
    // Fallback logic here

Packages

Organize and reuse code

use "email"
use "database"
use "ai"

// Now you can use functions from these packages
send_email("user@example.com", "Welcome!")
save_user(user_data)
var analysis = analyze_text(content)

Environment Variables

Configure your applications

var api_key = env("API_KEY")
var database_url = env("DATABASE_URL")

if api_key == null
    log "API_KEY not set"
    exit(1)
