What unique uniforms does Ghostty provide?

Ghostty includes specialized uniforms like iCurrentCursor (position and size), iCurrentCursorColor, iTimeCursorChange, and iTimeFocus.

What is the Ghostty Shader Development skill?

It is a specialized Claude Code skill that provides domain-specific guidance and code patterns for writing GLSL shaders to customize the Ghostty terminal's appearance.

How do I prevent my shader from making Ghostty unusable?

This skill emphasizes safety practices like incremental testing, initializing all variables explicitly, and avoiding the 'f' suffix on float literals to prevent compilation errors that cause black screens.

Does Ghostty support standard Shadertoy shaders?

Yes, Ghostty uses Shadertoy-compatible GLSL ES 3.0, though some specific Shadertoy uniforms like iMouse and iDate are not currently supported.

Can I animate effects based on terminal focus?

Yes, Ghostty provides an iFocus uniform (1 for focused, 0 for unfocused) which this skill uses to gate expensive animations or change visual states when you switch windows.

デザインツール

Simplifies the creation and optimization of custom GLSL shaders for the Ghostty terminal emulator.

概要

The Ghostty Shader Development skill provides a comprehensive toolkit for developers looking to enhance their terminal experience with custom visual effects. It offers deep expertise in GLSL ES 3.0 (WebGL 2.0) syntax and specialized Ghostty-specific extensions, such as focus-aware uniforms and cursor-tracking variables. By providing implementation patterns for CRT effects, dynamic blurring, and cursor animations, this skill helps users build sophisticated terminal aesthetics while ensuring performance efficiency and visual safety. It is particularly useful for users managing AI-first dotfiles who want to leverage Ghostty's hardware-accelerated rendering capabilities.
