I've been learning go and this is my first CLI app. There's definitely some YAGNI in this..cough emoji cough..but supporting unicode/emoji led me to expressing the charsets as an interface instead of as a string or array of characters, which are so nice and so lightweight in go.

brew install leighmcculloch/randstr/randstr

or

go install github.com/leighmcculloch/randstr/cmd/randstr

Feedback welcome, especially on project structure and best ways to distribute go CLIs.

Curious as to how the use of emoji and other unicode effects your password management.

I added unicode and emoji for fun which is where the YAGNI reference came from. I doubt many websites accept them, even Google don't. But you're welcome to give it a go:

randstr -charset ASCII,UnicodePassword
