Platform Validators
Reusable validation functions for configuration values.
Validators
Port Validator (port-validator.ncl)
Validates port numbers:
- Valid range: 1024-65535 (excludes system ports < 1024)
- Checks for unreserved ports
- Predicate functions for validation
Functions:
is_valid_port(port)- Returns boolis_unreserved_port(port)- Returns boolvalidate_port(port)- Returns {valid, error}is_system_port(port)- Returns bool
Budget Validator (budget-validator.ncl)
Validates cost tracking configuration:
- Role budget limits (must be > 0)
- Threshold percentages (0-100)
- Budget windows (daily/weekly/monthly)
- Complete budget limit validation
Functions:
is_valid_budget(cents)- Returns boolis_valid_threshold(percent)- Returns boolis_valid_window(window)- Returns boolvalidate_role_limits(limits)- Returns {valid, errors}validate_threshold(percent)- Returns {valid, error}
Usage Pattern
let port_validator = import "validators/port-validator.ncl" in
assert port_validator.is_valid_port 8080
let result = port_validator.validate_port 9001
if result.valid then
"Port OK"
else
"Port error: %{result.error}"
