Conversation
Implement support for Zenoh's attachment API, enabling key-value metadata
to be sent alongside messages. This adds:
- --attachment KEY=VALUE option for put, delete, and get commands
- --attachment-from-line option for put to extract attachments from stdin
- {attachment} and {attachment:KEY} format placeholders for output
- Helper functions for parsing and formatting attachments
- Comprehensive tests for all attachment functionality
Example usage:
zenoh put -k "sensor/temp" -v "23.5" --attachment "source=device1"
zenoh subscribe -k "sensor/*" --line "{value} (source={attachment:source})"
