Simplified CQL grammar

How to generate the grammar files

1. Install ANTLR 4.

   • On a Mac: brew install antlr.

2. Generate the Go files for the SimplifiedCql grammar:

   antlr -Dlanguage=Go antlr/SimplifiedCql.g4
   

Current ZDM code works with ANTLR 4.9.3, so if you have issues downloading it from system package managers you can:

1. Download JAR file from https://repo1.maven.org/maven2/org/antlr/antlr4/4.9.3
2. Generate Go files for simplified CQL grammar:

   java -Xmx500M -cp ".:/path/to/antlr4-4.9.3-complete.jar" org.antlr.v4.Tool -Dlanguage=Go antlr/SimplifiedCql.g4
