Quick Start

1. 1

   Create a file

   Create a file named hello.pseudo:

   hello.pseudoCopy

   # hello.pseudo
   name = "world"
   print "Hello, {name}!"

   Output

   Hello, world!
2. 2

   Run it

   bashCopy

   pseudo run hello.pseudo

3. 3

   Try an algorithm

   sort.pseudoCopy

   func bubbleSort(arr)
       for i from 0 to len(arr)
           for j from 0 to len(arr) - i - 1
               if arr[j] > arr[j+1]
                   swap arr[j] and arr[j+1]
       return arr
   
   bubbleSort([5, 2, 9, 1])

   Output

   [1, 2, 5, 9]
4. 4

   Step through it (educational mode)

   bashCopy

   pseudo run sort.pseudo --step

   The --step flag pauses at each line and shows variable state. Perfect for understanding how an algorithm progresses.

5. 5

   Try recursion

   fib.pseudoCopy

   recursive fibonacci(n)
       if n <= 1: return n
       return fibonacci(n-1) + fibonacci(n-2)
   
   fibonacci(10)

   Output

   55

Auto-print Behavior

A bare expression or function call at any level automatically prints its value - you don't need print everywhere:

x = 42
x          # → prints 42

arr = [1, 2, 3]
len(arr)   # → prints 3
