Command-Line Interface User Guide

Command-Line Interface (CLI) of webOS Open Source Edition (OSE) provides a collection of commands used for creating, packaging, installing, and launching apps or services in the command line environment. CLI allows you to develop and test apps or services without having to use a specific IDE.

Key Features

CLI provides the following key features:

• App and Service Creation
  • Provides standard templates for webOS OSE apps and services
  • Provides a list of available templates
  • Generates an app or a service and configures basic information
• App and Service Packaging
  • Packages the source code and generates a package file (.ipk) to run on the target device
  • Provides a feature to exclude sample and test code directories from an app or a service
• Target Device Management
  • Provides a list of target devices
  • Adds, modifies, and removes target devices
• App and Service Installation
  • Installs the app and service on the target device
  • Provides a list of apps installed on the target device
  • Removes selected apps from the target device
• App Launching and Closing
  • Launches selected apps
  • Closes apps that are running
  • Provides the list of apps running on the target device
• App and Service Debugging
  • Enables Web Inspector for debugging web apps
  • Enables Node's Inspector for debugging JavaScript services
  • Provides web app information
  • Provides JavaScript service information

System Requirements

Required version for each operating system are as follows:

Installing CLI

This section describes how to install CLI on your host machine.

Download the Package

First, download the CLI package for your operating system from the SDK download page.

Unzip the Package

Unzip the downloaded CLI package. After unzipping the package, you can execute the CLI commands located in the following directories.

• Windows: ares-cli\bin
• Linux & macOS: ares-cli/bin

Set the Path

To make it easy to execute CLI commands, you need to add the CLI directory to the PATH environment variable.

Windows

If you unzipped the package under C:\, the CLI commands would be located in C:\ares-cli\bin. You need to add the directory to the environment variable using one of the commands below in a command shell.

C:\> setx /m PATH "C:\ares-cli\bin;%PATH%"

C:\> setx PATH "C:\ares-cli\bin;%PATH%"

To make the changes take effect, you must restart the command shell.

Linux & macOS

There are many ways to set the environment variable in Linux and macOS. Here, we describe the method to add the information to the .profile so that the PATH is automatically configured each time the shell is executed. We will assume that CLI has been unzipped under the home directory.

First, open the .profile which is located in the home directory. If the file does not exist, the command will create one.

$ vi ~/.profile

Add the lines below at the end of the file.

...
# add CLI path
if [ -d "$HOME/ares-cli/bin" ]; then
  export PATH="$PATH:$HOME/ares-cli/bin"
fi

To make the changes take effect, you must execute the following command or restart the shell.

$ source ~/.profile

CLI Workflow

webOS OSE CLI provides features for developing web apps throughout the whole development process. The figure below shows some of CLI commands that can be used during each stage of the development process.

CLI Commands

The following table shows the available CLI commands.

ares-generate

This command creates a webOS app or service from a template. ares-generate displays a list of available templates for a web app, JS services, and webOS configuration files.

Usages

ares-generate [OPTION...] APP_DIR
