FFL is a CSS-like language that allows you to style LaTeX-typeset formula in a web environment.
The documentation is currently limited, but doc/cheatsheet.md should give you a quick intro.
We periodically update the demo on https://penn-hci.github.io/ffl/. To run this locally,
npm installin this directorycd sample/md-playgroundinto the main demo environment with markdown integrationnpm install&&npm run start
If all steps here are successful, you should see a react page pop up which you can experiment with.
On the right side under "FFL" you will be able to enter FFL stylings.
The root directory of this repo is the root directory of this project. It only contains the parsing and rendering of FFL and nothing on the editing environment. In src/ffl.ts you will find render and renderToHTML which emulate KaTeX, which are the main entry points for calling FFL on single formulas. An example integration can be seen in markdown-it-ffl which calls FFL to work with the markdown-it engine.
The project is still in its early stages and there are major changes incoming to the implementation. If you have ideas, submit an issue in the repo. If you want to get involved, get in touch with the authors of the project and we will try our best to help get you onboard. As this project matures, this process will likely also evolve and change.
