About this project
What does Feyflower add?
Feyflower
Feyflower is a guidebook API built with Lavender's Markdown parser and owo's Braid UI. While not a fork of Lavender, it shares many similarities as this project was created to replace it as a dependency of Trickster.

Features
- Fully data-driven, with in-UI hot reloading
- Injections, which allow extending or inserting pages into existing entries
- Advancement-locked entries, categories, and injections with support for complex conditions
- By default, Feyflower shows a toast when the contents of a book have changed in response to advancements
- Page tags which links and injections can use to target a page without knowing its index
- Templates with a clean syntax, optional arguments, and full access to the Markdown compiler
- Templates can insert arbitrary Braid widgets, automatically add tags, and more
- Custom Markdown extensions via LavenderMD's feature system, with entry-specific overrides
- Localization support, with a book-defined fallback language
- Book extensions for addons to add entries, categories, and injections to an existing book
- Built-in support for generating a web version of a book
- Offhand book rendering
Getting Started
Feyflower is still in very early alpha as we begin to port Trickster's book. Once it has stabilized a bit more, we will begin writing public-facing documentation.
Credits
Huge thanks to glisco for Braid UI and Lavender.
