go-repl

Quickly prototype some Go code without having to setup a temporary project, a file or even open your editor

Features

• remember previously entered lines
• multiline support by default
• import all go standard library packages and use them
• inline package imports, no need to keep em at the top of your input

Installation

go install github.com/xnacly/gorepl@latest

Usage

gorepl ships a repl and allows the execution of inputs via the -c cli flag.

Cli flag

$ gorepl -c 'println("Hello World")'
Hello World

Repl

The repl assumes multiline mode by default, end your input with ';' to execute it

Hello world

$ gorepl
go > println("Hello World");
Hello World

Using packages

$ gorepl
go > import "os"
>>>> cache, err := os.UserCacheDir()
>>>> import "fmt"
>>>> if err != nil {
>>>>   fmt.Println("Failed to get cache dir", err)
>>>>   return
>>>> }
>>>> fmt.Println(cache)
>>>> ;
/home/teo/.cache
go >

Why

I wanted a go repl to quickly prototype something or check if the behaviour of slices still match the idea i have in my mind :^).
