Local Golang playground
The simple mode for GNU/Emacs for setting up local Go language playground with
features similar (and with help of
go-mode even outperform!) service
at play.golang.org. You may treat it like the simple REPL for Go. This is
not a wrapper for working with play.golang.org from Emacs (it is already did by original go-mode),
this is complete alternative for setting local playground inside Emacs without using browser for
experiments with code snippets.
Web playground at play.golang.org is a nice idea. It has not require setup and it executes your
code in a restricted environment where you can't damage you system. But it brings many restrictions
too especially when you want use additional helpers for working with your code: formatters, code
completers etc. Emacs offers many such tools for Go development so it is the most comfortable play
with snippets inside Emacs instead of rude webeditor. Of course local playground requres you to
setup Go environment but if you developing in Go (or you want to do it) you are anyway would need
go-mode and helper tools for working with code in a comfortable way.
- it works under go-mode with all you plugins installed (like autocompletion, linters and so on)
- the playground files saved in the subdirectory under GOPATH that helps you keep library of useful snippets
- it could split the code into arbitrary number of files
- it could import any external packages from your GOPATH
- uses vendored packages in your snippet dir
- could be used with modules with the latest Go versions
gotest — these are mandatory. Setup any additional tools you want
for Golang (see Emacs Wiki for guides or google for "emacs+golang"). Personally I recommend use
goimports for automatically add import clauses to your snippets. Because usually when you test
some ideas you want get working code as fast as possible. And
goimports helps with it.
go-playground from MELPA:
M-x package-install RET go-playground
If you want share snippets use
gist-buffer from MELPA if you want publish gists on github.com.
The mirror repository of the project: https://notabug.org/grafov/go-playground. I really not think that this small project need the mirror but I just would like advertise a nice git hosting for FOSS. Try notabug.org for your projects! :)
- From any mode run
M-x go-playgroundfor start a new playground buffer filled with basic template for
mainpackage (see the picture below).
- Add your code then press
Ctl-Return(it bound to
go-playground-execcommand). It will save, compile and exec the snippet code.
- When you played enough with this snippet just run
M-x go-playground-rm. It will remove the current snippet with its directory and all files.
Mode not offers default bindings except
Ctl-Return. It just lefts the space for you.
For easy running the template declares
main package with defined
main() function. Each snippet
saved to its own directory (named by timestamp by default). Remember
go-playground runs the
go run *.go so any sources from the snippet directory will be included.

Using with go modules
By default the playground runs
go-command as it defined in settings of
go-mode. You could use
special customized compiler path with
go-playground-go-command. For using with modules it could
be used such way:
go-playground-init-commandto "go mod init".
- Try go-scratch it even simplier than
go-playground. But it prevents you from using many of tools because it not keeps code in files.
- gorepl-mode is REPL for Go, helpful for interactive research of code.

Future plans and accepting contributions
I don't want to make this package much complex. Most of
go-playground functions depends on other
go-mode. And it is good way. But one thing I want to add is snippet list buffer
where you can easily find and edit/delete snippets of your library. Bugfixes and small features
accepted as well.
