Manis

For build system plugins that need to fetch relative config files (like .fecsrc).

Install

npm install manis

Usage

Using strip-json-comments

var Manis = require('manis');
var stripJSONComments = require('strip-json-comments');

var loader = function (text) {
    return JSON.parse(stripJSONComments(text));
};

var manis = new Manis({
    files: [
        {
            // just for example, it should be loaded as yaml in fact.
            name: '.eslintrc',
            get: function (json) {
                return {eslint: json};
            }
        },
        '.fecsrc',
        {
            name: 'package.json',
            get: function (json) {
                return json.fecs || {};
            }
        }
    ],
    loader: loader
});

var options = manis.from('path/to/file.js');

// do something cool with options

NOTICE: the default loader strip comment after manis@0.3.0.

Loading .yml with js-yaml

var yaml = require('js-yaml');

var Manis = require('manis');

var loader = function (text) {
    return yaml.load(text);
};

var manis = new Manis('.travis.yml', {loader: loader});

var options = manis.from('path/to/file.js');

// do something cool with options

NOTICE: the default loader used js-yaml to load YAML and JSON content after manis@0.3.0.

With defaults

var Manis = require('manis');

var manis = new Manis({
    files: [
        '.fecsrc',
        {
            name: 'package.json',
            get: 'fecs'
        }
    ]
});

manis.setDefault('default/path/to/config/fecs.json');

var options = manis.from('path/to/file.js');

// do something cool with options

User config

var Manis = require('manis');

var manis = new Manis({
    files: [
        '.fecsrc',
        {
            name: 'package.json',
            get: 'fecs'
        }
    ]
});

manis.setDefault('default/path/to/config/fecs.json');

// will find `~/.fecsrc`
manis.setUserConfig();

var options = manis.from('path/to/file.js');

// do something cool with options

Within a gulp plugin

var Manis = require('manis');
var map = require('map-stream');

module.exports = function MyGulpPlugin(options) {
    var manis = new Manis('.fecsrc', options);

    return map(function (file, cb) {

        // get the options for this file specifically
        var options = manis.from(file.path);

        // do something cool

        // send the file along
        cb(null, file);

    });
};
