class Fontist::Indexes::UserIndex

Index for fonts installed in the user font directory

This index tracks all fonts installed in the user-specific font location (platform-dependent, typically with /fontist subdirectory) using a singleton pattern to ensure consistent state across the application.

## Responsibilities

• Maintain index of all user location fonts

• Provide fast font lookups by name and style

• Auto-rebuild when font directories change

• Cache results for performance

## Index File

Located at: ~/.fontist/user_index.default_family.yml

## Platform-Specific Paths Indexed

• macOS: ~/Library/Fonts/fontist/*/.{ttf,otf,ttc,otc}

• Linux: ~/.local/share/fonts/fontist/*/.{ttf,otf,ttc,otc}

• Windows: %LOCALAPPDATA%/Microsoft/Windows/Fonts/fontist/*/.{ttf,otf,ttc,otc}

## Usage

index = Fontist::Indexes::UserIndex.instance
fonts = index.find("Arial", "Bold")
index.add_font("/path/to/font.ttf")
index.rebuild(verbose: true)
