Can "snap info" be extended to list a snap's plugs and slots?

[Robert P. J. Day]

I think it would be useful if there was some way to ask the question, "What plugs and slots are defined for snap X?" For instance, if I run:
```
$ snap connections ubuntu-frame
Interface Plug Slot Notes
content - ubuntu-frame:ubuntu-frame-diagnostic -
content[graphics-core20] ubuntu-frame:graphics-core20 mesa-core20:graphics-core20 -
hardware-observe ubuntu-frame:hardware-observe :hardware-observe -
login-session-control ubuntu-frame:login-session-control - -
network-bind ubuntu-frame:network-bind :network-bind -
opengl ubuntu-frame:opengl :opengl -
wayland - ubuntu-frame:wayland -
x11 ubuntu-frame:x11 :x11
```
I can see that ubuntu-frame has a slot for wayland, but it would be more convenient if I could just ask, "What plugs and slots are defined by ubuntu-frame?" It seems as if "snap info" still has lots of room to display more info if one uses "--verbose", would it be hard to add this info to the output?

Hello,
Did you try 'snap interfaces <snap-name>' command?
Is that what you need?

Thanks

Yes, but that command is officially deprecated, see "snap interfaces
--help", and I'd prefer not to present commands in, say, a SC101 class that
might disappear without warning.

That command seems fine, except that it is officially deprecated so I am reluctant to make it part of the SC101 course.

Ok, it will be triaged soon

As a workaround snap connections can be used as well:

list of plugs
snap connections spotify | awk '{print $2}' | grep spotify: | cut -d ":" -f2

list of slots
snap connections spotify | awk '{print $3}' | grep spotify: | cut -d ":" -f2
