I come from a ruby background, and I just started learning go. Is there any standard way to install 3rd-party libraries that's comparable to RubyGems?
Go does have package management tool as well (similar like RubyGems for Ruby), it's called dep.
Usage example:
cd $GOPATH/src
mkdir testproject
cd testproject
# init project
dep init
# install 3rd party library
dep ensure -add github.com/labstack/echo
dep ensure -add github.com/novalagung/gubrak
dep generates Gopkg.toml file (similar like Gemfile for ruby). You can either install the 3rd party libraries through dep ensure -add command, or by adding the library metadata into Gopkg.toml then perform dep ensure.
Btw, there is also few other alternatives other than dep. For more information please take a look at https://github.com/golang/go/wiki/PackageManagementTools.
