ArchieML

Parse Archie Markup Language (ArchieML) documents into JavaScript objects.

Read about the ArchieML specification at archieml.org.

The current version is v0.5.0.

Installation

npm install archieml

Usage

var archieml = require('archieml');
var parsed = archieml.load("key: value");
>> {"key": "value"}

Parser options

Inline comments are now deprecated in ArchieML. They will continue to be supported until 1.0, but are now disabled by default. They can be enabled by passing an options object as the second parameter in load:

archieml.load("key: value [comment]");
>> {"key": "value [comment]"}

archieml.load("key: value [comment]", {comments: true});
>> {"key": "value"}

Using with Google Documents

We use archieml at The New York Times to parse Google Documents containing AML. This requires a little upfront work to download the document and convert it into text that archieml can load.

The first step is authenticating with the Google Drive API, and accessing the document. For this, you will need a user account that is authorized to view the document you wish to download.

For this example, I'm going to use a simple node app using Google's official googleapis npm package, but you can use another library or authentication method if you like. Whatever mechanism, you'll need to be able to export the document either as text, or html, and then run some of the post-processing listed in the example file at examples/google_drive.js.

You will need to set up a Google API application in order to authenticate yourself. Full instructions are available here. When you create your Client ID, you should list https://127.0.0.1:3000 as an authorized origin, and https://127.0.0.1:3000/oauth2callback as the callback url.

Then open up examples/google_drive.js and enter the CLIENT_ID and CLIENT_SECRET from the API account you created. And then run the server:

$ npm install archieml
$ npm install express
$ npm install googleapis
$ npm install htmlparser2
$ npm install html-entities

$ node examples/google_drive.js

You should then be able to go to https://127.0.0.1/KEY, where KEY is the file id of the Google Drive document you want to parse. Make sure that the account you created has access to that document.

You can use a test document to start that's public to everyone. It will ask you to authenticate your current session, and then will return back a json representation of the document. View the source of examples/google_drive.js for step by step instructions on what's being done.

Tests

A full shared test suite is included from the archieml.org repository, under /test. After running npm install, initialize the shared test submodules (git submodule init && git submodule update) and npm run test to execute the tests.
