💎 Hash Cron Directive in TuskLang for Ruby
Hash Cron Directive in TuskLang for Ruby
Welcome to the automated revolution with TuskLang's Hash Cron Directive! This is where we break free from the constraints of traditional cron systems and embrace the power of declarative, configuration-driven task scheduling. In Ruby, this means combining TuskLang's elegant hash directives with Ruby's powerful scheduling capabilities to create automated systems that are as expressive as they are powerful.
What is the Hash Cron Directive?
The Hash Cron Directive (#cron
) is TuskLang's declaration of independence from traditional cron systems. It allows you to define complete scheduled tasks, jobs, and automated workflows using simple hash configurations. In Ruby, this translates to powerful, declarative scheduling definitions that can be processed, validated, and executed with minimal ceremony.
Basic Cron Directive Syntax
Basic cron job definition
cron_job_config = {
"#cron" => {
"name" => "data-backup",
"schedule" => "0 2 *",
"handler" => "BackupJob#execute",
"timezone" => "UTC",
"enabled" => true,
"description" => "Daily database backup at 2 AM"
}
}Ruby class to process the cron directive
class CronDirectiveProcessor
def initialize(config)
@config = config
@tusk_config = load_tusk_config
end def process_cron_directive
cron_config = @config["#cron"]
return nil unless cron_config

schedule: cron_config["schedule"],
handler: parse_handler(cron_config["handler"]),
timezone: cron_config["timezone"] || "UTC",
enabled: cron_config["enabled"] || true,
description: cron_config["description"],
retry_policy: process_retry_policy(cron_config["retry_policy"]),
timeout: cron_config["timeout"] || 300
}
end
private
def parse_handler(handler_string)
return nil unless handler_string
job_class, method = handler_string.split("#")
{

}
end
def process_retry_policy(retry_config)
return {} unless retry_config
{
max_attempts: retry_config["max_attempts"] || 3,
backoff: retry_config["backoff"] || "exponential",
delay: retry_config["delay"] || 60

end
# Validate schedule format
if job_config["schedule"] && !valid_cron_schedule?(job_config["schedule"])
errors << "Job #{job_name} has invalid cron schedule: #{job_config['schedule']}"
end
# Validate handler format
if job_config["handler"] && !job_config["handler"].include?("#")

def self.valid_cron_schedule?(schedule)
# Basic cron schedule validation
parts = schedule.split(" ")
return false unless parts.length == 5
# This is a simplified validation - in production you'd want more robust validation
parts.all? { |part| part.match?(/^[\d*\/,\-]+$/) }
end
end
Usage example
config = {
"#cron" => {
"jobs" => {
"backup" => {
"schedule" => "0 2 *",
"handler" => "BackupJob#execute",
"description" => "Daily backup"
}
}
}
}Validate and optimize
errors = CronDirectiveBestPractices.validate_config(config)
if errors.empty?
optimized_config = CronDirectiveBestPractices.optimize_config(config)
documentation = CronDirectiveBestPractices.generate_documentation(config)
puts "Configuration is valid!"
puts "Documentation: #{documentation}"
else
puts "Configuration errors: #{errors}"
end
Conclusion
The Hash Cron Directive in TuskLang represents a revolutionary approach to task scheduling and automation. By combining declarative configuration with Ruby's powerful scheduling capabilities, you can create sophisticated, maintainable automated systems with minimal boilerplate code.
Key benefits: - Declarative Configuration: Define complete scheduled jobs in simple hash structures - Ruby Integration: Leverage Ruby's scheduling frameworks and ecosystem - Advanced Scheduling: Support for complex schedules, timezones, and dependencies - Monitoring and Metrics: Built-in monitoring, alerting, and performance tracking - Error Handling: Comprehensive retry policies and error recovery - Notifications: Flexible notification system for job status updates - Resource Management: Built-in resource monitoring and allocation
Remember, TuskLang is about breaking free from conventions and embracing the power of declarative, configuration-driven development. The Hash Cron Directive is your gateway to building automated systems that are as expressive as they are powerful!
