Modules

Modules help organize code into namespaces using a prefix (e.g., ModuleName~function).

---

1. Creating a Module

• All variables and functions in a module share a common prefix.
• The prefix must start with an uppercase letter and end with ~.

Example: Math Module

# Define functions in the Math module
function Math~add(a, b) do
    return (a + b)
end

function Math~sub(a, b) do
    return (a - b)
end

# Use the module
result = Math~add(5, 3)  # → 8
result = Math~sub(10, 4) # → 6

---

2. The loadNamespace Function

Loads all objects from a module without the prefix into the current scope.

Example

# Define a module
function Geometry~circleArea(r) do
    return (3.14159 * r ** 2)
end

# Load the module
loadNamespace("Geometry")

# Now use functions without prefix
area = circleArea(5)  # → 78.53975

Important Notes

• loadNamespace only affects already defined objects.
• It copies objects into the current scope (modifying them won’t affect the original module).

---

3. The import Keyword

Executes the contents of a .ne file (or AppVar on TI-EZ80).

Syntax

import "filename"  # Without .ne extension

Example

# File: math.ne
function add(a, b) do
    return (a + b)
end

# Main program
import "math"
print(add(2, 3))  # → 5

On TI-EZ80

import "MYPROGRAM"  # AppVar name (no extension)

Notes

• import can take multiple filenames.
• It must be on its own line or separated by ;.
