Eric Lilja commented on KARAF-3217:
-----------------------------------
[~jbonofre] I see, thanks for the clarification. Is "--show-hidden" not a valid
flag for the command "scr:list" anymore? Do you were is the best documentation
for the different scr-commands and what flags etc they accept?
Seems Felix gogo needs some improvements then. Throwing a stacktrace at you
seems wrong, even for invalid flags. It should ignore (and maybe warn), or fail
with an error stating the flag is unrecognized in the context (like git command
line program works, you know). And if a flag is in the wrong format, a nicer
error message explaining that would be good. Improving all of this is
long-term, I do realize that, but what can we do now?
