Syntax

Variables

Create variables using any of the following keywords:

• drop
• birth

        cook my_var = "Hello, MemeLang!"
        spawn num = 42
        summon list = [1, 2, 3, 4, 5]
        drop flag = true
        birth name = "MemeLang"
    

Printing Output

Display text using any of these keywords:

• print
• yell
• cow_say
• moo
• yap
• scream
• announce
• leak
• broadcast
• meow

        print "Hello, World!"
        yell "This is MemeLang!"
        cow_say "Moo! MemeLang is fun!"
        moo "MemeLang is udderly amazing!"
        yap "MemeLang is great for learning!"
        scream "MemeLang is the best!"
        announce "MemeLang is here!"
        leak "MemeLang is open source!"
        broadcast "MemeLang is taking over the world!"
        meow "MemeLang is purrfect!"
    

Conditions (If Statements)

Create conditional statements using:

• if
• sus
• what
• vibecheck
• checkin

        if x > 10 {
            print "x is greater than 10"
        }

        sus y == "hello" {
            print "y is hello"
        }

        what z < 5 {
            print "z is less than 5"
        }

        vibecheck a != 0 {
            print "a is not zero"
        }

        checkin b >= 100 {
            print "b is at least 100"
        }
    

Else Statements

Use these keywords for alternative execution paths:

• else
• nah
• no
• cap
• otherwise

        if x > 10 {
            print "x is greater than 10"
        } else {
            print "x is not greater than 10"
        }

        sus y == "hello" {
            print "y is hello"
        } nah {
            print "y is not hello"
        }

        what z < 5 {
            print "z is less than 5"
        } no {
            print "z is not less than 5"
        }

        vibecheck a != 0 {
            print "a is not zero"
        } cap {
            print "a is zero"
        }

        checkin b >= 100 {
            print "b is at least 100"
        } otherwise {
            print "b is less than 100"
        }
    

While Loops

Repeat code while a condition is true using:

• while
• grind
• farm
• loopmaxxing

        while x < 10 {
            print x
            x = x + 1
        }

        grind y > 0 {
            print y
            y = y - 1
        }

        farm z != "done" {
            print z
            z = get_next()
        }

        loopmaxxing a <= 100 {
            print a
            a = a * 2
        }
    

For Loops

Iterate through collections using:

• for
• touchgrass
• repeatbro

        for item in my_list {
            print item
        }

        touchgrass element in my_array {
            print element
        }

        repeatbro num in 1..10 {
            print num
        }
    

Functions

Define functions using any of these keywords:

• fn
• function
• skill
• spell
• move
• technique

        skill add(a, b) {
            yeet a + b
        }

        function greet(name) {
            yeet "Hello, " + name + "!"
        }

        spell factorial(n) {
            if n <= 1 {
                yeet 1
            } else {
                yeet n * factorial(n - 1)
            }
        }
        move max(a, b) {
            if a > b {
                yeet a
            } else {
                yeet b
            }
        }
    

Supporting Keywords

Examples

Fibonacci

        cook a = 0
    cook b = 1

    touchgrass item in [1,2,3,4,5,6,7,8] {
        yap a

        cook next = a + b
        a = b
        b = next
    }
    

Multiplication Table

    cook i = 1

    grind i <= 10 {
        yap 5 * i
        i = i + 1
    }
    

Countdown

        cook n = 10

        grind n > 0 {
            yap n
            n = n - 1
        }
        scream "BOOM!"
