Just started using bashdb yesterday, and I found it to be very useful. My use was simple: ran it in a terminal to step through a script to locate an odd problem with reading a delimited set of values into an array. As it turns out, I may have uncovered a bug in bashdb, or an issue with bashdb running against Bash 5.0 while executing a script with a shebang set to a Bash 3.2 binary.
Anyway, a bashdb integration makes sense. If that’s not possible, then feature parity with bashdb would be great.
