Dear Thomas

Many thanks for your great MQTT-Explorer! I added support for the "+" wildcard in search expressions.
Moreover, if the search expression contains a "+" wildcard the corresponding topic levels are grouped under a single node (re-)named to "+". For example, if there are messages available under the following topics:

  • a/GUID-1/x/y
  • a/GUID-1/u/v
  • a/GUID-2/u/w
    and the search expression is "a/+/" the displayed tree becomes
a ¬
   + ¬
      x ¬
      |  y
      u ¬
         v
         w.

Would love to see this feature merged into a future release. Parts of it might also contribute to issue #69.

P.S. By the way, what are your plans for this project? Any chances you return? Any chances you release it under a more community friendly license?

  "+" in topic tree.
Watchout, the search expression changed to be case sensitive.
  This has been carefully considered. The internal switch to regular expressions
  and the use of that expression for the replacement in the topic tree has led
  to two options
  a) entering a search expression leads to a topic tree with all text lower cased
     (independent of the casing in the search expression)
  b) making the search expression case sensitive. Replacement does not change
     casing of original topics.
  Since MQTT-Topics are case sensitive themselves, option b) has been chosen.
