antlr4-javascript-sql

An UMD module wrapping ANTLR generated parser, lexer, listener and visitor for SQL databases, based on the antlr4-javascript-sparql module by Szymon Danielczyk.

Info

Parser classes where generated from G4 grammar files using the ANTLR runtime, version 4.5.1.

The SQL grammar file is Copyright (c) 2014 by Bart Kiers, released under the MIT License; it can be downloaded from the antlr/grammars-v4 repository.

Classes have been generated with the following commands:

 -Xmx500M -cp "antlr-4.5.1-complete.jar:$CLASSPATH" org.antlr.v4.Tool -Dlanguage=JavaScript grammars/sql/SQL.g4 -o lib

Then a the following modifications have been made to generated classes:

• each class has been wrapped in a function for dependency injection
• in SQLLexer, atn and decisionToFDA have been moved inside the constructor
• in SQLParser atn, decisionToFDA, sharedContextCache have been moved inside the constructor; atn has been bound to this and the Object.defineProperty has been commented out

Usage

To build UMD module type:

install -g browserify
install": "browserify  --ignore-missing main.js -o release/antlr4-sql.js",

To use with webpack define following shim antlr4-sql.js

antlr4 = require('antlr4-base');
SQLLexer = require('node_modules/antlr4-javascript-sql/lib/SQLLexer.js');
SQLParser = require('node_modules/antlr4-javascript-sql/lib/SQLParser.js');
SQLListener = require('node_modules/antlr4-javascript-sql/lib/SQLListener');
SQLVisitor = require('node_modules/antlr4-javascript-sql/lib/SQLVisitor');

listener = SQLListener(antlr4);
visitor = SQLVisitor(antlr4);

le.exports = {
LLexer: SQLLexer(antlr4),
LParser: SQLParser(antlr4, listener, visitor),
LListener: listener,
LVisitor: visitor
