antlr4ng

JavaScript + TypeScript Target Runtime for ANTLR 4

This package is a fork of the official ANTLR4 JavaScript runtime, with the following changes:

• Much improved TypeScript type definitions.
• XPath implementation.
• Vocabulary implementation.
• Complete Interval implementation.
• Consistent formatting (indentation, semicolons, spaces, etc.).
• Numerous smaller fixes (null instead of undefined and others).
• Smaller node package (no test specs or other unnecessary files).

It is a drop-in replacement of the antlr4 package, and can be used as such. For more information about ANTLR see www.antlr.org. More details about the JavaScript/TypeScript target can be found here.

Release Notes

1.0.2

• Github build action
• Updated package.json
• Exported ErrorNode

1.0.1

• Added and/or replaced all copyrights to a common ANTLR version.
• Removed all individual default exports. Only the final lib exports contain both, default and non-default exports. This avoids namespace access like antlr4.atn. Everything is available under a top level import.
• Renamed ErrorListener to BaseListener, as that is what it is actually when comparing it to the Java runtime.

1.0.0

• Initial release.
