Nope, it's not a typo. nut package is a library (package nut), nut/nut is a tool/command (package main).

Are you sure? Well, I bet you're sure, but I can't use nut properly if i go get -u github.com/AlekSi/nut, and it works like a charm if I go get the nut/nut sub-project.

@kavu You should type as written in README: go get -u github.com/AlekSi/nut/....

[kavu]

@AlekSi Oh! 😧 Another amazing feature from Go toolchain. I definitely need to dive deeper into go get sources now. But the question is - why does go get -u github.com/AlekSi/nut/nut still works?..

[AlekSi]

go get -u github.com/AlekSi/nut/... clones repository and installs nut and every subpackage in nut/ recursively. Dependencies are go get -u.
go get -u github.com/AlekSi/nut/nut clones repository and installs package nut/nut. Dependencies are go get -u. nut/nut depends on github.com/AlekSi/nut so it's also installed.
