v0.21.1

Changed

• Interactive: Show cursor on search input

Fixed

v0.21.0

Changed

• Provide better error output on initial MQTT connection errors
• Interactive: When payload is focused it can occupy more space when needed.

• Log: Provide machine-readable newline-delimited output with --json
• Log: Print --verbose to stderr instead of stdout

Special thanks

• To @gjabell for the improvements of the log sub-command
• To @orhun for adding mqttui to the official Arch Linux repos

v0.20.0

This ended up being quite a big release with a lot of new and improved features.
In case I have broken something, feel free to open an issue!
Otherwise, enjoy the new release!

Added

• Interactive: Topic search
• Interactive: History table entry is selectable (keyboard & mouse) to view a payload in detail
• Interactive: Scrolling moves view not selection and has scrollbars
• Interactive: graph plots values with units will ignore everything after the whitespace (20.0 °C → 20.0)
• Publish from stdin (and with that from file contents)
• Support for decoding MessagePack payloads
• Support for binary payloads
• Interactive: Truncate payloads to ´--payload-size-limit´ for reduced RAM usage
• Auto-generated man pages from CLI definition (clap)

Changed

• Interactive: Fewer borders for more content characters like longer topics in the overview
• Interactive: Display version & broker in the lower right corner
• Interactive: Display MQTT connection error in its own area
• Interactive: Only display keys in footer when useful
• Interactive: JSON Payload takes only required space for bigger history/graph view
• CLI: Group MQTT connection related options in --help
• Read One: Output raw payload or --pretty
• Build: always build with TLS support
• Performance: Debounce input events on interactive draw (especially noticeable on many events like scrolling)
• Performance: Fewer clones on interactive draw
• Performance: Don't keep Timezone information of each message
• Performance: Don't clone each incoming MQTT payload
• Performance: Don't clone TLS private key on startup

Fixed

• Keep selected JSON object keys selected (by key, not by index as before)
• Always quit on Ctrl + C (q still only quits when not typing anything)
• Catch panics on interactive and clean up terminal correctly before displaying them

Thanks
