Glyphs Vanilla Ui

Vanilla GUI Library Skill

Query the Vanilla GUI library (schriftgestalt/vanilla fork) used by Glyphs 3 for building plugin UIs — windows, buttons, text fields, lists, and more.

> Run all scripts from this skill's base directory. Prepend the base directory path to scripts/ when executing.

Vanilla Path

${GLYPHS_VANILLA_PATH:-~/Library/Application Support/Glyphs 3/Repositories/vanilla/Lib/vanilla}

If GLYPHS_VANILLA_PATH is not set, try GLYPHS_REPOSITORIES_PATH/vanilla/Lib/vanilla, then the default path above.

Quick Start: Browse All Components

Read __init__.py (≈107 lines) to see every exported class and which module it comes from:

Read $VANILLA/__init__.py

This shows all from vanilla.moduleName import ClassName lines — the complete component inventory.

Quick Start: Read a Component

For multi-class files (vanillaWindows.py, vanillaList2.py, etc.), use the script to extract a single class:

python3 scripts/read_component.py Button                # Full: source + docstring + methods
python3 scripts/read_component.py Window --summary      # Summary: methods list (no source)

For single-class files (vanillaCheckBox.py, vanillaSlider.py, etc.), just Read directly:

Read $VANILLA/vanillaCheckBox.py

Quick Start: Search Components

# Find a component by keyword
Grep "class.*Button" $VANILLA/

# Find all classes in a module
Grep "^class " $VANILLA/vanillaWindows.py

# Find usage of a specific method
Grep "def setTitle" $VANILLA/

Quick Start: Official Documentation

Fetch component docs from the vanilla website:

WebFetch https://vanilla.robotools.dev/en/latest/objects/{ComponentName}.html

Replace {ComponentName} with the actual class name (e.g., Button, Window, List2).

Glyphs-Specific Notes

Palette Plugins Use Group, Not Window

Palette plugins receive a Group as their container — never create a Window inside a palette. Use Group with embedded controls.

posSize Convention

All Vanilla components use posSize = (left, top, width, height):

• Use "auto" for Auto Layout managed dimensions
• Negative values for width/height mean "from right/bottom edge"

Auto Layout

Use VerticalStackView and HorizontalStackView for modern Auto Layout UIs instead of manual posSize positioning.

GridView

GridView is conditionally imported (requires macOS 10.12+). It appears in a try/except block at the bottom of __init__.py.

Common Workflow

1. Find component → Read $VANILLA/__init__.py to browse all exports
2. Read API → python3 scripts/read_component.py ComponentName for details
3. Check docs → WebFetch https://vanilla.robotools.dev/en/latest/objects/ComponentName.html
4. Search patterns → Grep "pattern" $VANILLA/ for usage examples
