Read ALCE

Reads the entire contents of an ALCE file.

Installation

$ npm install utils-fs-read-alce

Usage

var read = require( 'utils-fs-read-alce' );

read( path, [ options,] clbk )

Reads the entire contents of an ALCE file.

read( '/path/to/data.alce', onData );

function onData( error, data ) {
	if ( error ) {
		console.error( error );
	} else {
		console.log( data );
	}
}

The function accepts the same options as fs.readFile(), but encoding is always set to utf8. In addition, the function supports ALCE#parse options.

read( '/path/to/data.alce', {'meta':false}, onData );

function onData( error, data ) {
	if ( error ) {
		console.error( error );
	} else {
		console.log( data );
	}
}

read.sync( path[, options] )

Synchronously reads the contents of an entire ALCE file.

var out = read.sync( '/path/to/data.alce' );
if ( out instanceof Error ) {
	throw out;
}
console.log( out );

The function accepts the same options as fs.readFileSync() and supports ALCE#parse options.

Examples

var path = require( 'path' ),
	read = require( 'utils-fs-read-alce' );

var file = path.join( __dirname, 'config.alce' );

// Sync:
var data = read.sync( file, 'utf8' );
// returns <object>

console.log( data instanceof Error );
// returns false

data = read.sync( 'beepboop', {
	'encoding': 'utf8'
});
// returns <error>

console.log( data instanceof Error );
// returns true


// Async:
read( file, onRead );
read( 'beepboop', onRead );

function onRead( error, config ) {
	if ( error ) {
		if ( error.code === 'ENOENT' ) {
			console.error( 'ALCE file does not exist.' );
		} else {
			throw error;
		}
	} else {
		console.log( 'Port: %s.', config.server.port );
	}
}

Tests

Unit

Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:

$ make test

All new feature development should have corresponding unit tests to validate correct functionality.

Test Coverage
