## Introduction
## Requirements ## Requirements
Recent version of Linux, Windows or MacOS, with recent C++ compiler that has C++17 (1z) support (e.g. gcc 6.0, MSVC 2017, clang 6.0), and python 3.6 or above.
## Usage ## Usage
`python3 prompt.py` will launch the interactive command prompt. The server binary will be autometically rebuilt and started.
#### Commands:
- `<sql statement>`: parse sql statement
- `f <filename>`: parse all sql statements in file
- `print`: printout parsed sql statements
- `exec`: execute last parsed statement(s)
- `r`: run the last generated code snippet
- `save <OPTIONAL: filename>`: save current code snippet. will use random filename if not specified.
- `exit`: quit the prompt
