go-jsonnet

This an implementation of Jsonnet in pure Go. It is feature complete but is not as heavily exercised as the Jsonnet C++ implementation. Please try it out and give feedback.

This code is known to work on Go 1.8 and above. We recommend always using the newest stable release of Go.

go get github.com/clipperhouse/gen
go get github.com/clipperhouse/set
export PATH=$PATH:$GOPATH/bin  # If you haven't already
go generate

Generated Stdlib
