SLIME for Golang?

Getting Help
1

Is there an Golang interpreter/incremental compiler with a REPL which is (or could be) integrated into Emacs like SLIME for Common Lisp?

I donā€™t know about slime, but motemen/gore and d4l3k/go-pry are the first two Google hits for ā€œgo replā€. Maybe those can work.

gore and go-pry are note real REPL. (IIRC!)

they take advantage of the very quick compilation speed of Go to recompile the snippets you enter and re-run those parts.

real REPLs are:

there are also Jupyter backends for Go:

(they do have to use/implement a real REPL for Jupyter to work correctly)

e.g. a Jupyter backend with Neugram:

direct examples:

hth,
-s

Thanks Iā€™ll check out gomacro.

I see what you mean, it looks like cheating if the REPL simply calls the standard compiler.
However, as long as the REPL looks and feels like a REPL, I would not care about whether the code is compiled or interpreted.

it kind of makes all the difference in the world when you do:

$> sat, err := launchSatellite()

and then:

$> err = analyze(sat.Data)

you donā€™t want another satellite to be launched when you enter the second command in the REPL.
something that the REPLs-yet-not-quite try hard not to do, of course, but fail in some situations.

Valid point. On the other hand, not all one-liners launch a satellite.

^---- Sorry. The above line sat in the editor for 16 days, unnoticed by me.

Looks like there is a new REPL that is able to interpret Go source code line-by-line:

Yes, Jasonā€™s interpreter is interesting in the sense that itā€™s, to my knowledge, the first non-toy JIT interpreter for Go.
The one thing that I donā€™t like very much is that itā€™s relying on installing a C-based third party library to work.
So no easy ā€˜go getā€™ experience, no AppEngine and no painless cross compilation :slight_smile:
I still prefer ā€˜myā€™ neugram interpreter :slight_smile:
