export CLASSPATH=".:${PWD}/antlr-4.9-complete.jar:$CLASSPATH"
alias antlr4='java -Xmx500M -cp "${PWD}/antlr-4.9-complete.jar:$CLASSPATH" org.antlr.v4.Tool'
alias grun='java -Xmx500M -cp "${PWD}/antlr-4.9-complete.jar:$CLASSPATH" org.antlr.v4.gui.TestRig'

antlr4 -Dlanguage=Go -package planparserv2 -o generated -no-listener -visitor Plan.g4

All generated code will be under directory generated.
