Options

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

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.

exportVar	Behavior
null	default Will set variable to module.exports
function(filename){}	should return the desired variable name
'' (empty string)	convenience value to set variable to 'filenameparser'
