Lodash for QML

This is a simple Lodash wrapper for QML. The installation process is not quite convenient yet, but stay tuned :) Maybe, I will update it in a few centuries.

Installation

Get the wrapper source

$ mkdir 3rdParty
$ cd 3rdParty
$ git clone https://bitbucket.org/gooroo/qml-lodash.git

Get the Lodash itself

I've bundled the latest available version (which is 4.17.5) with the wrapper, but I strongly recommend you to re-generate it with the freshest one:

$ npm install -g lodash-cli
$ cd qml-lodash/lodash
$ lodash exports="none" iife=";(function () {%output% root._ = _; }.call(this));" -o lodash.js

Update your QML import path

Please, refer to the official documentation. I tried it with both local file-system paths and Qt Resource system paths, and it works.

Usage

import QtQuick 2.10
import QtQuick.Window 2.10

import lodash 4.17  // import the library

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello Lodash")

    Component.onCompleted: {
        function megaprint(v) {
            console.log(JSON.stringify(v))
        }

        // and it magically works here who knows why:
        megaprint(
            _.partition([1, 2, 3, 4], function (n) { return n % 2 })
        )

        megaprint(
            _([1, 2, 3]).map(function(n) { return n * 2})
        )
    }
}

Output

qml: [[1,3],[2,4]]
qml: [2,4,6]
