One of the promising one is go-fish, with limited import option, you can install it using these commands:
go get -u -v github.com/rocky/go-types
go get -u -v github.com/rocky/go-loader
go get -u -v github.com/rocky/go-fish
go build make_env.go
make
mv go-fish $GOPATH/bin
One thing that annoys me is no history (Up/Down key) and limited set of import (that can be added), but I haven't found a way to import package on runtime.
Another one that quite promising is gore, to install it use run these commands:
# workaround for moved astutil repository
mkdir $GOPATH/src/golang.org/x/tools/go/ast
ln -s $GOPATH/src/golang.org/x/tools/astutil $GOPATH/src/golang.org/x/tools/go/ast
go get -u -v github.com/nsf/gocode
go get -u -v github.com/k0kubun/pp
go get -u -v github.com/davecgh/go-spew
go get -u -v golang.org/x/tools/cmd/godoc
go get -u -v github.com/motemen/gore
Gore is one that works fine, to import package use colon, import and package name without quote, for example:
:import fmt
You can also use Tab key for auto complete, Up/Down key to see typed commands, Ctrl+D for canceling last command, but you cannot erase 1 previous word using Alt+Backspace. I think this program has the less annoyance than other alternatives.
