Ares 2

Overview

Ares 2 is an open-source (Apache 2) browser-based code editor and UI designer for developing Enyo 2 applications.

Applications made using Ares 2 rely on the Enyo highly portable web technology: they are cross-platform (Linux/Mac/Windows, Android,/iOS/WindowsPhone/Windows8/webOS, Chrome/IE/Firefox/Opera), cross-form-factors (Desktop, Phone, Tablet, TV… etc).

Roadmap

Current status

Although Ares is still a work in progress, we have reached the point where we are opening the repo and will do further development in the open, so we encourage you to follow our progress and give us feedback as we push Ares forward.

You can give us feedback either via the Ares category of the EnyoJS Forums or via the EnyoJS JIRA (using the ares component).

Here are the main features you can start looking at today:

De-centralized file storage
- Ares currently connects to a filesystem component, to edit local files (via the fsLocal Hermes service). Ares can also be configured to use a per-user Dropbox account (via the fsDropbox Hermes service) as file storage. See below for more details.
- Key goals with this approach are to avoid forcing users to store files and/or credentials on Ares servers and allow freedom to choose the preferred storage location, whether cloud or local.
Code editor
- Ares integrates the ACE (Ajax Cloud Editor, used by Cloud9 & Mozilla) code editor for code editing
Code intelligence
- Upon opening/editing a JavaScript file, Ares will parse the file and display a semantic outline of the code in the right-hand panel (for purposes of demonstrating parser)
- Code completion using symbols from:
  - the current project
  - the Enyo version that comes with Ares
  - the libraries included in the project
- In the future, this will be used for advanced features context-sensitive documentation, etc.
UI designer for drag and drop UI editing
- Component definitions are round-tripped from the Editor to the Designer, meaning that changes made in one will immediately appear in the other.
Integration with PhoneGap online build
Project sources
- Allow creation of new projects based on bootplate templates.
- Allow creation of new projects based on your own project templates.
- See Project sources for more information

Future plans

The following features are in the works, and you should see them added as we move forward:

More code completion and context-sensitive documentation
Additional Hermes components to extend the local and cloud file storage options: We plan to add Hermes components for FTP, Box.net and more
Improvements to the Designer component for greater ease of use
... and more!

Note: An up-to-date view of the ongoing activities is available from The ARES JIRA, itself available from the EnyoJS JIRA.

Usage

Configuration

Proxy

Depending on your network environment, you may need to setup a proxy URL to access Internet through a proxy server.

This proxy URL can be set up with:

https_proxy or http_proxy environment variable. I.e you can run node server with a command like http_proxy=http://my-proxy.com:8080 node ide.js
edit the globalProxyUrl parameter at the beginning of ide.json file to have something like `globalProxyUrl: "http://my-proxy.com:8080"'
specific proxy per service. See "Advanced proxy setup" at the end of this document.

By default, the service will get the proxy specified by globalProxyUrl parameter or by https_proxy environment variable or by http_proxy environment variable.

Language

Language used by Ares 2 is english per default (and forced). See the language configuration entry in ide.json. If the related language does not exist, a language will be defined according to the locale hierarchy managed by the ilib library. This forced value could be modified / disabled: another language code string value / null.

NB: Don't forget to restart Ares 2.

Install

Install Node.js 0.10.19 (or later) & its associated NPM (Node Package Manager) from a binary distribution, for example at nodejs.org
Install ares-ide using NPM:
```
 $ npm -d install ares-ide
```
The -d options gives some minimal troubleshooting information, which is pretty useful as ares-ide is a heavy package (more than 12 MB).
Once installed, run it using node_modules/.bin/ares-ide (or node_modules\.bin\ares-ide.cmd) on Windows.
Please report the issues you find in our JIRA at https://enyojs.atlassian.net/ against the component named ares.

NB: Since ares-0.2.12, ares is minified as it is installed

Run

Start the IDE server: (e.g. using the Command Prompt, navigate to the ares directory and type node ide.js)…

C:\Users\johndoe\node_modules\.bin> ares-ide.cmd

… or (Mac & Linux):

$ node_modules/.bin/ares-ide

In case you want to access other parts of your machine's file-system, refer to the local filesystem service configuration

Creating an application

Once Ares is loaded in your browser, you can create a skeleton of an application with "Edit -> Create ... " menu. Once you've selected a directory to create a project, you will see a popup to specify the name, title and other parameters of your project.

To create a project skeleton, use the "Template" selector to choose the latest bootplate version. This way, your project will be created with a template of an application and the required enyo, layout and extra libraries.

Updating Enyo libraries in your application

The simplest way is to update the libraries inside your project.

For Enyo:

remove enyo directory
download latest release from enyo release page
unpack in your project and rename the directory to enyo

For all libraries in lib:

remove each directory in lib
download the latest release for layout and extra libraries
unpack each library and rename the directories to extra and layout

Reporting Issues

Be sure to run Ares with --log (or -L) to capture the Ares server output in the file name ide.log. Attach this log-file to you bug report on the ARES JIRA.

You may also want to increase the log verbosity, in order to better understand what is going wrong by yourself. The default verbosity level is http. You may want o increase to info or even verbose. Lowest layer silly is usually for Ares core developers.

$ node ide.js --level=info

Known Bugs

See this list of known issues

Features

PhoneGap Build

See Hermes README: PhoneGap build service.

Dropbox

See Hermes README: Dropbox File-System service.

Security

Ares does not store any security token or credentials on the server. Client-side security tokens & credentials are stored either using Cookies or using HTML5 localStorage.

See Hermes Security: Authentication.

Extend

Ares's plugin architecture is made to allow extensions, both in its UI (browser client) & its server.

Project sources

The service genZip defined in ide.json of ares-project or ide-plugin.json of Ares plugins allows to intanciate new Ares project from project templates such as "bootplate" or any customer specific project templates.

The property sources: of the service genZip lists the template definitions that are available at project creation time.

See the section "Project template service" in hermes/README.md for more information.

Ares plugins

Ares plugins can bring additional functionality and configuration to Ares. An Ares plugin must follow these rules to be loaded as a plugin:

It must be installed in a directory under "ares-project/node_modules".
It must have an ide.json in its main directory, which:
- defines a new service entry
- can define the client side code to load in the browser
- can update some previously defined services (e.g.: modify/add project templates)

Startup of "node ide.js"

At startup, the process "node ide.js":

loads the file ide.json
locates the plugins, using the first of the below method that works:
1. files ../../node_modules/*/ide-plugin.json (production environment: npm installs Ares plugins aside Ares)
2. files node_modules/*/ide-plugin.json (development environment: npm installed Ares plugin under the Ares source tree)
sorts then in lexicographical order
merges them into the loaded configuration following the algorithm described in the next section. While merging each plugin into the global configuration, the following variables are substituted:
- @PLUGINDIR@: the absolute location of each plugin root folder in the Ares server file-system.
- @PLUGINURL@: the URL to the plugin root URL, taken relatively to the Ares main page.
Globally substitute the following variables in the merged configuration:
- @NODE@: the path to the Node.js executable in use. This is useful to start sub-process using the same executable
- @CWD@: Current-Working-Directory of the Ares process
- @INSTALLDIR@: Root folder of ares-project, as it is loaded by Node.js. This is the expected location of the ide.js main script.
- @HOME@: the user's $HOME folder on Mac OSX & Linux, %USERPROFILE% on Windows.
starts services defined in the resulting loaded configuration

Merging configuration

Ares plugin configuration are merged as follow:

New service entries are simply added to the current configuration
Service entries already existing in the current configuration are merged property by property as follow:
- New properties are simply added to the existing service entry
- For array, array entries are added to the corresponding array in the existing service
- For objects, object properties are applied to the corresponding object in the existing service
- Other properties of same type are applied to overwrite the corresponding entries in the existing service
- Properties with same name but different types are considered as errors and stop the startup process.
Other top level properties are not yet taken into account

Client side Ares plugin

The client code of an Ares plugin is defined by the property "pluginUrl" of a service entry in "ide.json".
During the initialization process of Ares within the browser, the 'ServiceRegistry' will perform an 'enyo.load' of the javascript file (Usually a 'package.js' file) specified by the property "pluginUrl".
After being loaded, the new code must invoke ServiceRegistry.instance.pluginReady(); to notify Ares that the client side code is ready.
See the function 'pluginReady' in the file 'services/source/ServiceRegistry.js'.

Ares logo

It is possible to customize the logo displayed on the top-right corner of Ares.

For this, load your logo in ares (recommended size is 42x42px). Change the following line in utilities/source/Logo.js in the create function:

		this.setSource("path-to-your-logo");

To remove the logo's display from Ares, replace the call to this.setSource("path-to-your-logo") by:

		this.hideLogo();

Advanced Proxy settings

Proxy can be configured per service in Ares ide.json configuration file. Sample advanced proxy configuration is provided in ide.json with the Xproxy and XproxyUrl parameters.

To setup a proxy specific to a service:

locate the service you want in ide.json
remove the X from XproxyUrl and Xproxy name
configure your proxy in the value of these parameters.

Example:

"proxyUrl": "http://myproxy.some.where.org:8080",
