Constant Naming Convention

Property	Value
Rule Code	NTX2
Severity	Style

Background

Using UPPER_SNAKE_CASE for constants is a widely adopted convention that improves code readability by making it easy to distinguish constants from other variables.

Purpose

Ensures that constants are named in UPPER_SNAKE_CASE.

Example

Consider the following Vyper code:

# Non-compliant - constant 'threshold_value' is not in UPPER_SNAKE_CASE
threshold_value: constant(uint256) = 1000

# Compliant
MAX_VALUE: constant(uint256) = 1000
TOTAL_SUPPLY: constant(uint256) = 100000

In this example, threshold_value would be flagged by the rule. MAX_VALUE and TOTAL_SUPPLY are compliant.
