Antlr4 Go Examples

Getting started

mkdir antlr4test
cd antlr4test
mkdir src
export GOPATH=`pwd`
go get github.com/wxio/antlr4-go
go get github.com/wxio/antlr4-go-examples
cd src/github.com/wxio/antlr4-go-examples
go generate ./...
go test ./...

The go generate command read the source and executes commands specified by in //go:generate xxx lines. The example has such a line, which calls the Antlr4 tool and then sed to replace the import statement in the generated code.

Issues

This only works on OSX as the sed for OSX is different. To get this to work in Linux or Windows, change the sed command or edit the creating and modifying a generate file (eg. gen_linux.go).
