Download artifacts easily

DLoad simplifies downloading and managing binary artifacts for your projects. Perfect for development environments that require specific tools like RoadRunner, Temporal, or custom binaries.

Why DLoad?

DLoad solves a common problem in PHP projects: how to distribute and install necessary binary tools and assets alongside your PHP code. With DLoad, you can:

• Automatically download required tools during project initialization
• Ensure all team members use the same versions of tools
• Simplify onboarding by automating environment setup
• Manage cross-platform compatibility without manual configuration
• Keep binaries and assets separate from your version control

Installation

composer require internal/dload -W

Command Line Usage

DLoad offers three main commands:

List Available Software

# View all available software packages
./vendor/bin/dload software

This displays a list of all registered software packages with their IDs, names, repository information, and descriptions.

DLoad comes with a pre-configured list of popular tools and software packages ready for download. You can contribute to this list by submitting issues or pull requests to the DLoad repository.

Show Downloaded Software

# View all downloaded software
./vendor/bin/dload show

# Show detailed information about specific software
./vendor/bin/dload show rr

# Show all available software, including those not downloaded
./vendor/bin/dload show --all

This command displays information about downloaded software.

Download Software

# Basic usage
./vendor/bin/dload get rr

# Download multiple packages
./vendor/bin/dload get rr dolt temporal

# Download with specific stability
./vendor/bin/dload get rr --stability=beta

# Use configuration from file (without specifying software)
./vendor/bin/dload get

# Force download even if binary exists
./vendor/bin/dload get rr --force

Download Command Options

Option	Description	Default
--path	Directory to store binaries	Current directory
--arch	Target architecture (amd64, arm64)	System architecture
--os	Target OS (linux, darwin, windows)	Current OS
--stability	Release stability (stable, beta)	stable
--config	Path to configuration file	./dload.xml
--force, -f	Force download even if binary exists	false

Project Configuration

Setting Up Your Project

The dload.xml file in your project root is essential for automation. It defines the tools and assets required by your project, allowing for automatic initialization of development environments.

When a new developer joins your project, they can simply run dload get to download all necessary binaries and assets without manual configuration.

Create dload.xml in your project root:

<?xml version="1.0"?>
<dload xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:noNamespaceSchemaLocation="https://raw.githubusercontent.com/php-internal/dload/refs/heads/1.x/dload.xsd"
       temp-dir="./runtime"
>
    <actions>
        <download software="rr" version="^2.12.0" />
        <download software="dolt" />
        <download software="temporal" />
        <download software="frontend" extract-path="frontend"/>
    </actions>
</dload>

Then run:

./vendor/bin/dload get

Configuration Options

The dload.xml file supports several options:

• temp-dir: Directory for temporary files during download (default: system temp dir)
• actions: List of download actions to perform

Download Action Options

Each <download> action supports:

• software: Name or alias of the software to download (required)
• version: Target version using Composer versioning syntax (e.g., ^2.12.0, ~1.0, 1.2.3)
• extract-path: Directory where files will be extracted (useful for non-binary assets)

Handling Different File Types

DLoad handles both binary executables and regular files:

<software name="my-app">
    <!-- Binary executable that depends on OS/architecture -->
    <binary name="app-cli" pattern="/^app-cli-.*/" />
    
    <!-- Regular file that works on any system -->
    <file pattern="/^config.yml$/" />
</software>

Automatic Binary Downloads with Composer Update

Integrate DLoad with Composer to automatically download required binaries whenever dependencies are updated. This ensures your team always has the necessary tools without manual intervention.

Add the following to your composer.json:

{
    "scripts": {
        "post-update-cmd": "dload get --no-interaction -v || echo can't dload binaries",
        "get:binaries": "dload get --no-interaction --force -vv"
    }
}

This configuration:

• Automatically downloads required binaries after composer update
• Provides a custom command composer get:binaries to force download all binaries with detailed output

Custom Software Registry

Defining Custom Software

Create your own software definitions:

<?xml version="1.0"?>
<dload xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:noNamespaceSchemaLocation="https://raw.githubusercontent.com/php-internal/dload/refs/heads/1.x/dload.xsd"
>
    <registry overwrite="false">
        <!-- Binary software example -->
        <software name="RoadRunner" alias="rr"
                  homepage="https://roadrunner.dev"
                  description="High performant Application server">
            <repository type="github" uri="roadrunner-server/roadrunner" asset-pattern="/^roadrunner-.*/" />
            <binary name="rr" pattern="/^roadrunner-.*/" />
        </software>

        <!-- Non-binary files example -->
        <software name="frontend" description="Frontend assets">
            <repository type="github"
                        uri="my-org/frontend"
                        asset-pattern="/^artifacts.*/"
            />
            <file pattern="/^.*\.js$/" />
            <file pattern="/^.*\.css$/" />
        </software>

        <!-- Software with mixed file types -->
        <software name="my-tool" description="Complete tool suite">
            <repository type="github" uri="my-org/tool" />
            <!-- Binary executables -->
            <binary name="tool-cli" pattern="/^tool-cli.*/" />
            <binary name="tool-worker" pattern="/^worker.*/" />
            <!-- Configuration files -->
            <file pattern="/^config\.yml$/" extract-path="config" />
            <file pattern="/^templates\/.*/" extract-path="templates" />
        </software>
    </registry>
</dload>

Software Configuration Options

Each <software> entry supports:

• name: Display name (required)
• alias: Short name for command line usage
• description: Brief description
• homepage: Website URL

Repository Options

The <repository> element configures where to download from:

• type: Currently supports "github"
• uri: Repository path (e.g., "username/repo")
• asset-pattern: Regex pattern to match release assets

Binary Options

The <binary> element defines executable files:

• name: Binary name that will be referenced
• pattern: Regex pattern to match the binary in release assets

Binary files are OS and architecture specific. DLoad will automatically download the correct version for your system.

File Options

The <file> element defines non-binary files:

• pattern: Regex pattern to match files
• extract-path: Optional subdirectory where files will be extracted

File assets don't have OS/architecture restrictions and work on any system.

GitHub API Rate Limits

To avoid GitHub API rate limits, use a personal access token:

GITHUB_TOKEN=your_token_here ./vendor/bin/dload get

You can add this to your CI/CD pipeline environment variables for automated downloads.

Use Cases

Local Development Environment Setup

Automatically download required tools when setting up a development environment:

# Initialize project with all required tools
composer install
./vendor/bin/dload get

CI/CD Pipeline Integration

In your GitHub Actions workflow:

steps:
  - uses: actions/checkout@v2

  - name: Setup PHP
    uses: shivammathur/setup-php@v2
    with:
      php-version: '8.1'

  - name: Install dependencies
    run: composer install

  - name: Download binary tools
    run: |
      GITHUB_TOKEN=${{ secrets.GITHUB_TOKEN }} ./vendor/bin/dload get

Cross-Platform Development Team

Configure once, use everywhere:

<dload xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:noNamespaceSchemaLocation="https://raw.githubusercontent.com/php-internal/dload/refs/heads/1.x/dload.xsd"
>
    <actions>
        <download software="rr" version="^2.12.0" />
        <download software="temporal" />
    </actions>
</dload>

Each team member runs ./vendor/bin/dload get and gets the correct binaries for their system (Windows, macOS, or Linux).

Distributed Frontend Assets

Keep your frontend assets separate from your PHP repository:

<software name="frontend-bundle">
    <repository type="github" uri="your-org/frontend-build" asset-pattern="/^dist.*/" />
    <file pattern="/^.*$/" extract-path="public/assets" />
</software>
