REPL Commands

Some functionalities are provided as colon-commands:

:import <package path>  Import package
:print                  Show current source
:write [<filename>]     Write out current source to file

Installation

gore uses Go toolchains, so I don’t provide binaries.

go get -u github.com/motemen/gore

Make sure $GOPATH/bin is in your $PATH.

Also recommended:

go get -u github.com/nsf/gocode
go get -u github.com/k0kubun/pp # or github.com/davecgh/go-spew
go get -u golang.org/x/tools/cmd/godoc

FAQ/Caveats

• If you see too many arguments in call to mainScope.LookupParent while installing gore, run go get -u golang.org/x/tools/go/types.

• gore runs code using go run for each input. If you have entered time-consuming code, gore will run it for each input and take some time.

TODO

• Undoing input

• Configuration

• :write completion

• Direct editing of code

• Using external sources

• API
