What is preferable for automatic code generation: using YAML or manual writing?

Using YAML for automatic code generation is preferable when:

• It is necessary to standardize and simplify the description of configurations or schemas.
• Parameters need to be changed quickly without editing the source code.
• The project supports code generation from descriptions (e.g., OpenAPI, Kubernetes manifests).

Manual coding is suitable for unique logic and complex scenarios where generation is impractical.

Thus, YAML is convenient for declarative description and automation, reducing errors and speeding up development.
