Hi there!

Use os.UserHomeDir() instead of go-homedir for Go version 1.12+.

@mgrachev is there an issue with using the https://github.com/mitchellh/go-homedir package?

@jharshman No, this is a dependency and I prefer to minimize dependencies in my projects.

@mgrachev Trimming back dependencies is always good, however, the go-homedir package itself is very small and not dependent on Go version. I could see this comment giving the impression to a user that if s/he is using Go 1.12+ that s/he would need to edit the code to use os.UserHomeDir().

@mgrachev I'm confused about this. How does adding this comment to the source help? Are we expecting users to change their dependency source if they are using Go 1.12+?

@spf13 Yes, you're right. I've added this comment because I didn't want to drop support for previous versions of Go.

I'm not sure what value there is in adding a comment. I do think there is some value in removing dependencies. One way to do this without breaking older users of Go is to incorporate build tags.
That is, create two alternative files, with a single function in each, one using the dependency and one calling os.UserHomeDir and use build tags to manage which one is included.

I'm going to close this because it introduces complication without enough benefit.

Commenting on a closed PR is pretty bad form, but os.UserHomeDir depends on the "$HOME" environment variable being set, whereas go-homedir uses a number of different strategies and basically always works whether "$HOME" is set or not.

Looks like this has been done by #1337 and released in Cobra 1.2.
