Options

Plugin redirects passed options directly to PEG, so read its documentation for details.

Wrappers

The generated source can be wrapped in different ways:

exportVar option

This option is inspired by grunt-peg plugin, and defines variable to which the generated parser will be assigned in the output file. Default value is module.exports.

angular option

This option is inspired by grunt-peg plugin. It creates an Angular module with a factory containing the generated source.
