# RSQL Parser (C++) with SQL WHERE Generator
|
|
|
|
This small example demonstrates:
|
|
- A lexer + parser for a subset of RSQL (supports `;` AND, `,` OR, parentheses).
|
|
- `=in=` and `=out=` list operators.
|
|
- An AST implementing `accept()` for the Visitor pattern.
|
|
- A `SQLBuilderVisitor` that generates an SQL `WHERE` clause.
|
|
|
|
Build:
|
|
```bash
|
|
mkdir build && cd build
|
|
cmake ..
|
|
cmake --build .
|
|
```
|
|
|
|
Run (example):
|
|
```bash
|
|
./rsql_parser "(status=in=(OPEN,CLOSED);priority==HIGH),category=out=(internal,test)"
|
|
```
|
|
|
|
The program prints the AST (evaluator) and the generated SQL WHERE clause. |
