About Go Play Space

Go Play Space is an experimental alternative Go Playground
frontend that is built in Go itself (using GopherJS),
a Go→JavaScript transpiler, and Vecty,
a React-like frontend library for GopherJS).

Try it: https://goplay.space

Go Play Space supports the Turtle graphics mode to help visualize algorithms and make learning experience more fun.

Features

1. Syntax highlighting, auto-closing braces and quotes, proper undo/redo, auto indentation
2. Smart help lookup: double-click on e.g. package keyword
   or Println function name in source code, and you will see
   the relevant help topic.
3. Live syntax error checking
4. Error line highlighting (both for syntax errors and for errors
   returned from the compiler)
5. Ability to highlight lines and blocks of code (like on Github, but better!) —
   just click on the line numbers. Use Shift and Ctrl
   to modify the selection
6. Keyboard shortcuts (see button captions)
7. Support for several UI themes
8. Support for Fira Code font
   (either the one installed in your system or a webfont)
9. go imports is always run before running your code, so you don’t usually
   have to worry about imports at all

Code execution is proxied to the official Go Playground, so your programs will work the same.
Shared snippets are also stored on golang.org servers.

Running Locally

Download the package:

$ go get -u github.com/iafan/goplayspace/...

Compile both client-side code and server binary:

$ cd $GOPATH/src/github.com/iafan/goplayspace/bin
$ ./build-client && ./build-server

Run the server:

$ ./goplayspace

Then open http://localhost:8080/ in your browser.

Troubleshooting

If you have trouble compiling the client, please make sure you have the latest version of GopherJS installed by running go get -u github.com/gopherjs/gopherjs (see #6)
