configucci/docs/file_format_spec.md

The config.json.xml file defines environment-specific configurations and a template for generating JSON output. Key syntax points:

• <environment name="...">: Defines a named environment (e.g., DEFAULT, env1, env2).
• <parameter name="..." value="..."/>: Sets key-value pairs for parameters (e.g., host, port, MessageBrokerHosts).
• @param_name@: Placeholder in the template that gets replaced with actual parameter values.
• @env_name@: Placeholder replaced with the current environment name.
• "[ ... ]": Array syntax for list values like MessageBrokerHosts.
• Template uses JSON format with placeholders for dynamic substitution.

The template generates a final JSON config by replacing all @...@ placeholders with corresponding parameter values from the active environment.
