Conditional Logic and Boolean Operators in Standard

Standard uses boolean logic to control the flow of your programs. Every condition you write evaluates to either true or false, and code inside a conditional block only executes when that evaluation returns true. You can compare values using all standard comparison operators:

price 5
print (price == 5) #Prints true
print (price = 5)  #Prints true
print (price < 5)  #Prints false
print (price > 5)  #Prints false
print (price >= 5) #Prints true

If-Equals Shorthand

Because Standard does not use = to assign values to variables, you can omit = entirely when checking value equality inside a condition. This shorthand makes equality checks more concise.

This shorthand is for comparing values. When you use ==, Standard compares memory addresses rather than values — so two variables holding the same number can return false with == if they are stored at different addresses.

print (p 5)  #Prints true
print (p 7)  #Prints false

f1 7
f2 7

print (f1 f2)    #Prints true, uses equals-short-hand
print (f1 == f2) #Prints false, values at different addresses

If Conditions

A simple if condition uses the syntax if: ARGS { ... }:

if: 7 > 5 {
    print "Duh!"
}

If-Else

To handle an alternative condition, chain an else: clause with its own arguments and block:

in number

if: number > 5 {
     print "Nice, more than 5 is great!"
} else: number < 0 {
     print "Number should be more than 0!"
}

Shorthand If-Else

When your else branch has no condition of its own, you can omit the else keyword and attach the fallback block directly with :{:

if: 5 < 7 {
    print "5 is less than 7! YAY!"
}:{
    print "Your computer can't do math!"
}

Boolean Operators

Build more complex conditions by combining boolean expressions with and, or, &, &&, |, or ||:

in username "Username: "
in psswd "Password: "

if: username "" and psswd "" {
    print "Welcome in!"
}:{
    print "Denied"
}

Negation

Prepend a boolean value or variable with ! to negate it:

bool true
print !bool #Prints false
