Package Exports

regexp2

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (regexp2) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Contributing

To run tests:

$ npm install
$ npm test

This will also automatically compile index.js.

The key source files are src/grammer.pegjs which is compiled using pegjs and src/index.js which is a CommonJS module with a special additional pseudo import statement.
