gore VS gosnip

There are also Go interpreters with REPLs like https://github.com/x-motemen/gore

There are a few REPLs, but people don't use them much. I usually have an empty main.go file laying around where I put a snippet, then run it.

I only know of this one and an article on it. https://github.com/x-motemen/gore , http://diego-pacheco.blogspot.com/2018/07/writing-simple-repl-in-go.html

Most people use the playground as a sort of a poor man's REPL. I don't find it useful for that due to the reasons I pointed above (feedback latency). You don't have to use an IDE, there are many other tools available that fill that role outside the IDE like https://github.com/x-motemen/gore that I have also used in the past.

The only actual Go REPL I know is gore, https://github.com/x-motemen/gore, which, on all the machines I've tried, is brutally slow.

That's the one I'm aware of https://github.com/motemen/gore

I while ago I wrote a tool called "gosnip" that allows you to run snippets of Go code from the command line (it runs the snippet through goimports to detect what imports are needed, and then compiles and runs it using go run). You can get it here: https://github.com/benhoyt/gosnip
