How to generate source code files from grammar

Grammar is located inside ClickHouseLexer.g4 and ClickHouseParser.g4 files.

To generate source code you need to install locally the antlr4 binary:

cd src/Parsers/New
antlr4 -no-listener -visitor -package DB -Dlanguage=Cpp ClickHouseLexer.g4  # if you have changes in a lexer part of grammar
antlr4 -no-listener -visitor -package DB -Dlanguage=Cpp ClickHouseParser.g4

Commit only git-tracked generated files - not all of the generated content is required.
