## 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.
