Unexport is a tool which unexports nonused exported identifiers. It was created as a part of Go challenge #5. Checkout the examples below
go get github.com/fatih/unexportUnexport exported identifiers in the encoding/pem package:
$ unexport -package encoding/pem
Process the package and display any possible changes. It doesn't unexport exported identifiers because of the -dryrun flag
$ unexport -package github.com/fatih/color -dryrun
Unexport only the "Color" and "Attribute" identifiers from the github.com/fatih/color package. Note that if the identifiers are used by other packages, it'll silently fail
$ unexport -package github.com/fatih/color -identifier "Color,Attribute"
