/shader-retire — Retire a Shader

Move a shader out of the active set into legacy/shaders_retired/ by display name, disk name, or filename.

Invocation

• /shader-retire Matrix Rain
• /shader-retire matrix_rain
• /shader-retire matrix_rain.json

Steps

1. Resolve the Shader

The argument can be:

• Display name (e.g., Matrix Rain) — scan src/shaders/**/*.json (including mouse/ and selection/ subdirs), match on the "name" field (case-insensitive)
• Disk name (e.g., matrix_rain) — look for src/shaders/matrix_rain.json, src/shaders/mouse/matrix_rain.json, or src/shaders/selection/matrix_rain.json
• Filename (e.g., matrix_rain.json or matrix_rain.hlsl) — strip extension, use as disk name

If no match found, list available shaders and stop.

2. Read Metadata

Read the matched .json file to discover iChannel texture files referenced in "iChannels" and the shader's directory.

3. Move Source Files

Create legacy/shaders_retired/ if it doesn't exist, then move all files belonging to the shader from its directory (src/shaders/, src/shaders/mouse/, or src/shaders/selection/) into it:

• {name}.glsl
• {name}.hlsl
• {name}.json
• Any iChannel textures listed in the metadata (e.g., {name}_i0.png)

Only move files that exist — don't error on missing .glsl (some shaders may not have the original).

4. Regenerate Bundles

powershell -File tools/shader_bundle.ps1

This regenerates src/gui/shader_bundle.ahk and src/gui/shader_resources.ahk, and cleans stale textures from resources/img/shaders/.

5. Run Tests

.\tests\test.ps1

6. Report

Summarize what was retired (list each moved file).
