Control Flow

Control Flow

NXL uses {} to define blocks.

A conditional has the form:

if age >= 18 {
    print("Adult")
} else {
    print("Minor")
}

Blocks are represented in the AST and environments provide the mechanism for nested scopes.

Current status

Conditional syntax can be represented by the parser and AST, but conditional runtime execution is still being developed.

The current runtime roadmap includes:

• Boolean expression evaluation
• Comparison evaluation
• if / else execution
• Loops
• break
• continue

This distinction is important:

Parser support ≠ Runtime support

A language feature normally needs to exist across multiple layers.
