Installation
The gore command requires Go tool-chains on runtime, so standalone binary is not distributed.
go get -u github.com/motemen/gore/cmd/gore
Make sure $GOPATH/bin is in your $PATH.
Also recommended:
go get -u github.com/mdempsky/gocode # for code completion
FAQ/Caveats
- gore runs code using
go runfor each input. All the inputted lines are
evaluated again and again so you can't bind the evaluated time by
time.Now(), for example. If you don't like this behavior, you may want to use
yaegi. - gore support Go modules. You can load local modules when you start gore at
the project directory. You don't need togo getto check the usage of a
remote repository,:import github.com/...will automatically download that
module. Also, you don't need togo getthe pretty print module anymore. If
you want to load a local code from$GOPATH, you need to create the modules
file (go mod init ...) and then start gore at the project directory.
