Windows Terminal Shaders

Shaders for the new Windows Terminal

How to use

• Checkout the repository
• Set the value for experimental.pixelShaderPath in your terminal setting to the desired shader
• optional: Add keybindings for turning the shader on/off and focusmode

Example Setting

Please add the lines you need to your own config, this example config only show the values that you need to add.

{
  "profiles": {
    "defaults": {
      // Add your desired shader
      "experimental.pixelShaderPath": "C:\\gitrepos\\windows-terminal-shaders\\crt.hlsl"
    },
  },
  "keybindings": [
    // It's recommended to add those two toggles for ease of use
    {
      "command": "toggleFocusMode",
      "keys": "shift+f11"
    },
    {
      "command": "toggleShaderEffects",
      "keys": "shift+f10"
    }
  ]
}

Transparent

Turn a specific color into transparent for use with useAcrylic and acrylicOpacity when xterm colors are enabled, like in vim themes.

Settings

Set the color value for the chromaKey used for transparency float3(8.0f / 0xFF, 8.0f / 0xFF, 8.0f / 0xFF) is the same as rgb(8, 8, 8)

static const float3 chromaKey = float3(8.0f / 0xFF, 8.0f / 0xFF, 8.0f / 0xFF);

Hue Shift

Changes the hue of screen colors. This can apply a color correction similar to the tint knob of old TVs or it can be set to cycle the colors smoothly over time.

Settings

HUE_OFFSET [0.0, 1.0)f : Adjust the hue to a specific offset.
CHANGE_RATE [0.0, 1.0)f : Changes the hue over time. For small values like 0.01f, this will cause a slow change over time and probably won't be very disruptive. TOLERANCE [0.0, 1.0)f : Saturation% setpoint. All saturation levels greater or equal than this will be affected by the hue adjustments. This allows you to fix some of the grayscale colors such as those offten used by on-screen text.

#define HUE_OFFSET 0.0f
#define CHANGE_RATE 0.01f
#define TOLERANCE 0.266f
