Fugue SQL Antlr Parser

This is the dedicated package for the Fugue SQL parser built on Antlr4. It consists of two packages: fugue-sql-antlr and fugue-sql-antlr-cpp.

fugue-sql-antlr is the main package. It contains the python parser of Fugue SQL and the vistor for the parser tree.

fugue-sql-antlr-cpp is the C++ implementation of the parser. This solution is based on the incredible work of speedy-antlr-tool, a tool that generates thin python interface code on top of the C++ Antlr parser. This package is purely optional, it should not affect the correctness and features of the Fugue SQL parser. However, with this package installed, the parsing time is ~25x faster.

Neither of these two packages should be directly used by users. They are the core internal dependency of the main Fugue project (>=0.7.0).

Installation

To install fugue-sql-antlr:

pip install fugue-sql-antlr

To install fugue-sql-antlr and fugue-sql-antlr-cpp:

pip install fugue-sql-antlr[cpp]

We try to pre-build the wheels for major operating systems and active python versions. But in case your environment is special, then when you install fugue-sql-antlr-cpp, please make sure you have the C++ compiler in your operating system. The C++ compiler must support the ISO C++ 2017 standard.
