Common

Types

var _ = require('man');

_.type(null); // => null

Collections

var _ = require('man');

// Convert to array
_.arr(arguments);

// Filter values with certain type
_.filterType(list, 'string');
_.filterTypes(list, ['number', 'undefined']);

// Remove values with certain type
_.removeType(list, 'string');
_.removeTypes(list, ['number', 'undefined']);

// Create object with all properties set to true
_.flagger(['prop1', 'prop2']); // => { prop1: true, prop2: true }

// Improved iteration
_.for(list)
    .check(function (value, i) {
        if (_.type(value) === 'string') {
            return false;
        }

    })
    .each(function (value, i) {
        // ...
    })
    .done(function () {
        
    });

// Map collection to object
_.mapToObject(list, function (value, i) {
    return {
        name: 'item' + i,
        value: value
    };
});

Math

var _ = require('man');

// Random number
_.rand(min, max);

// Generates random unique key
_.randomKey([prefix]);

var obj = {};
_.set(obj, 'prop1.prop2.prop3', true);
obj // => { prop1: { prop2: { prop3: true } } }

// Returns `name` property of `obj` object recursively

        prop2: {
            prop3: true
        }
    }
};
_.get(obj, 'prop1.prop2.prop3'); // => true 

// Flattens object to flat structure

            prop3: true
        }
    }

// Removes HTML-tags from string
_.removeTags(str);

// Trim string by specified symbol

/*
Search `sub` in `str` and returns array with objects {
    content: String,
    groups: Array,
    length: Number,
    start: Number,
    finish: Number
}
*/
_.search(str, sub, ignoreCase);

// Replace all found `sub` in `str` with `source`
_.replace(str, sub, source, ignoreCase)

// Same as `search` but returns `false` if nothing found
_.find(str, sub, ignoreCase);

// Capitalizes string
_.capitalize(str);

// Decode ASCII string
_.decodeChars(buffer);

// Decode Unicode string
_.decodeUnicode(buffer);

CML

var _ = require('man');
