Yet another Go REPL that works nicely. Featured with line editing, code completion, and more.

(Screencast taken with cho45/KeyCast)

Usage

gore

After a prompt is shown, enter any Go expressions/statements or commands described below.

To quit the session, type Ctrl-D.

Features

• Line editing with history

• Multiline inputs

• Package importing with completion

• Evaluates any expressions or statements

• No "evaluated but not used"

• Code completion (requires gocode)

• Pretty printing (pp or spew recommended)

• Showing documents (requires godoc)

• Auto-importing

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
:doc <expr or pkg>      Show document (requires godoc)
:help                   List commands

Installation

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

go get github.com/motemen/gore

Also recommended:

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

Caveats

• 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
