Generated with the plugin's renderer. This GIF demonstrates the rain; it does not show the portal transition.

What it does

• Digital-rain startup screen: green character streams with no title or prompt by default.
• Matrix light portal: once the host UI is ready and you interact, a narrow rectangular portal opens from the center toward both sides to reveal Harness. A fade transition is also available.
• Optional replay: play on application startup, or replay when a supported desktop window is restored from the background or minimized state. Switching Web browser tabs does not replay it.
• Green UI theme: remap the UI's blue accent colors to green. Choose Rain, Classic, or Teal presets, adjust the hue, or turn the theme off independently.
• Adjustable rendering: control rain density, speed, quality, and light/dark appearance. Light mode uses dark green characters on a white background.

The animation uses Canvas2D without video or online animation assets. It releases the rain renderer and animation frames after the transition. When the system requests reduced motion, the portal uses a fade instead.

Install and use

Search for dsh-codefall in dsh-market or in your desktop app's plugin manager. If the app provides an Add Plugin field, enter:

dsh-codefall

Wait for installation to finish, enable the plugin, then fully quit and restart the application.

The default sequence is: launch → digital rain → move the pointer, click, scroll, or press a key → portal opens → enter Harness. The host UI must be ready before the portal transition begins.

“On application startup only” means every fresh application launch, not once after installation. Restoring an application that stayed in the background does not replay the animation in this mode. Select the window-reopen option to replay it on supported desktop restores.

For a Web profile:

dsh plugin --profile web add dsh-codefall

If your desktop environment is managed through the CLI and its profile is actually named desktop:

dsh plugin --profile desktop add dsh-codefall

Prefer the app's own plugin manager when the desktop app provides one. The following alternatives are for CLI-managed environments; adjust the profile, path, and package filename to match your setup:

# Install from GitHub
dsh plugin --profile web add github:4444Hao/dsh-codefall

# Install a package you have already downloaded
dsh plugin --profile web add "D:\Downloads\dsh-codefall-0.2.0.tgz"

Settings

Open the plugin's “开机动画 codefall” settings page. Its location depends on your Harness or desktop app version. The linked screenshot shows the current Chinese settings UI; the English labels in the table explain the options.

View the Windows desktop settings screenshot.

It shows replay on window reopen, interaction dismissal, the Matrix portal, 90% density, ×1.20 speed, and Classic green at 120°. These are example settings, not the defaults.

Saved playback and transition changes apply to subsequent playback without another restart. Green theme and hue changes take effect immediately. The 3-second automatic option still waits for the host UI to be ready.

Light digital rain

View light digital rain: dark green characters on a white background. The same renderer supports both appearances. Follow the host theme or choose an appearance in settings.

View the green hue comparison: source blue, Classic green at 120°, Rain green at 145°, and Teal at 165°.

This is a color-mapping diagram, not a full application screenshot. The hue control changes the UI theme; it does not recolor the rain characters.

Compatibility and notes

• Harness 0.2.0-rc.2 or newer is recommended. Fully quit and restart after installing or updating the plugin.
• Replay on window restore depends on desktop visibility events. The current implementation targets desktop pages using the dsh-app: protocol; other desktop wrappers need separate verification.
• The Windows settings screenshot is linked above. The portal has been checked in a browser preview and offline tests. Real tray/minimize restore still needs the manual acceptance checks, documented in Chinese. macOS and Linux have not been tested on actual devices; a fully covered window may also produce visibility events on macOS.
• Host versions and third-party plugins can define their own colors. Green-theme coverage depends on whether they use the host's theme variables.
• Disable or uninstall the plugin in the app's plugin manager to remove its theme layer. For CLI-managed environments, use dsh plugin --profile web remove dsh-codefall, replacing the profile as needed.

Development and preview

See Matrix portal and window-restore playback for implementation details and acceptance records, in Chinese. Open preview/index.html locally, select “就绪” (Ready), then “交互” (Interact) to preview the portal. This is an offline demonstration rather than an actual Harness window.
