hl7js-grammar\nHL7 Grammar Parser(hl7js compatible) for Node.js\n\n# Installation\ninstall via [NPM](https://www.npmjs.com/):\n\u003e npm install hl7js-grammar\n\n# Usage\n## Initializing:\n```javascript\n\nvar parser = require('hl7js-grammar');\n\n```\n\n## reader.read(expression, callback)\n```javascript\n\n/// Basic Parsing\n/// Ref: http://www.interfaceware.com/blog/hl7-segment-grammar-notation/\nvar grSimple = 'MSH PID NK1 PV1';\nvar grOptional = 'MSH PID NK1 PV1 [PV2]';\nvar grMultiple = 'MSH PID {NK1} PV1 [PV2]';\nvar grOptionalMultiple = 'MSH PID [{NK1}] PV1 [PV2]';\nvar grGroup = 'MSH PID [{OBR {OBX}}]';\n\nvar expression = grGroup;\nparser.parse(expression, function (err, grammar) {\n    console.log(err);\n\n    console.log('ip: ', expression);\n    console.log(JSON.stringify(grammar));\n});\n\n/// Prints the following\n/// ip:  MSH PID [{OBR {OBX}}]\n/// [{\"id\":\"MSH\",\"required\":true},{\"id\":\"PID\",\"required\":true},{\"id\":\"OBR\",\"required\":false,\"isArray\":true,\"isGroup\":true,\"grammar\":[{\"id\":\"OBX\",\"required\":true,\"isArray\":true}]}]\n\n```\n\n## Output format\nOutput is compatible to be used with hl7js\n\n```javascript\n\n/// Format\nvar grammar = [\n{\n    id: 'Segment_ID',\n    required: true,\n    isGroup: true,\n    isArray: true,\n\n    grammar: [\n    ]\n];\n\n/// Example\nvar oruGrammar = [\n    {\n        id: 'MSH',\n        required: true\n    },\n    {\n        id: 'PID',\n        required: true\n    },\n    {\n        id:
