I am getting the following when I am trying to invoke sshs on Arch Linux:

panic: runtime error: index out of range [0] with length 0

I have tried installing AUR as well as binaries from the releases section. What am I missing?

[quantumsheep]

It seems to happen when you have an empty host config with spaces after the Host directive but without anything else.

[quantumsheep]

It's fixed in 3.1.0.

I'll try to update the package on the AUR, it requires Go 1.18 so I'm not sure if that's easy or not. In the meantime you can use the prebuilt binaries attached to the tag.

Yes, you are right I indent the lines after host for readability. The problem is fixed in 3.1.0, thanks a lot!
