flash-font-ass

A command-line tool that orchestrates the flash-font ecosystem to automatically load required fonts for ASS (Advanced SubStation Alpha) subtitle files before playback.

When provided with an ASS subtitle file, flash-font-ass will:

1. Parse the subtitle using ass-font and extract all required fonts.
2. Synchronize your underlying font database using flash-font.
3. Query the database to find the physical paths for the required fonts.
4. Temporarily inject those fonts into your Windows session using flash-font-injector.

Installation

cargo install flash-font-ass --locked

Setup & Configuration

Before you start using flash-font-ass, you must initialize the configuration. This creates a config file and specifies the root directory where your fonts are stored.

flash-font-ass init

The application will prompt you to enter the full absolute path to your font directory. This path will be saved along with an automatically determined location for the SQLite database (fonts.db).

Usage

Once configured, you can load fonts for an ASS file before turning on your video player:

flash-font-ass load --subtitle "path/to/subtitle.ass"

The fonts will remain loaded in the Windows system font table as long as the flash-font-ass process stays alive, or they will be automatically unloaded when it terminates (subject to the FontManagerConfig behavior).
