It would be great if there could be an example of "Read in a yaml file. Edit the hash--either add a new key and value or update and existing one--write the results back out. I struggled with the emitter and docs vs doc.

Thanks

The yaml parser can parser yaml files with multiple documents, so it returns 'docs'. But the emitter only support one document, you can dump your document with docs[0], or manually iterator over docs and dump each document.

Thanks. Adding a key and value to parsed yaml from file?
