Purge retained topics hierarchy - recursive removal about mqtt-explorer HOT 12 CLOSED

Has been released

from mqtt-explorer.

@thomasnordquist It would be great to enable recursively more than 50 topics. If you're worried about users shooting themselves in the foot, you could make it a hidden "power user" option to enable unlimited recursive deletes. I have several topics from using Home Assistant that I need to delete, and they have thousands of subtopics.

Thought about it, dismissed it because I did not know where to put the button.
I actually think this is a great feature to purge a tree of unused retained topics.
I'll add it to the todo list.

I think the recursive model is a bit too powerful, it could potentially clear the hole broker and therefore have unforeseen side-effects.
I think I'll add keyboard support, so one can navigate with the arrow keys and clear topics with backspace/delete keys.

That's a shame as it would have been so useful to me. Hive include this functionality as a plugin. I understand the concern but there could be a warning dialog or even an 'advanced features' enable option somewhere. My topics that I wanted to delete are hundreds of sub topics. I couldn't use a delete on each topic.

Yes please, ran into this recently and ended up purging the entire Mosquitto database to get the job done!

I limited the removal to 50 topics per click, this will be enough to get most of the tiresome work done, without being a "nuke".

Funfact: This feature works well with the search function.
Example: Search for topics containing "PowerState", select the root topic and do the "recursive removal".
The result: All topics containing "PowerState" have been removed.

Will be even more powerful when one can customize the search funktion: Use regex, limit search to topic or message body.

@thomasnordquist I can second @larstobi 's opinion. I am also working with Home Assistant and it is quite tiring to reset (delete) all the topics.
Maybe it can be introduced as a hidden setting? Or a key combination?
There are definitely "power users" here who know what they are doing. Please give them the option to do what they want. :)

I used a workaround by using a mqtt CLI to recursively delete them.
