Fountain-Plus

Fountain-Plus implements the Mangaplay format with Fountain to extend screenplay functionality and add storyboard capabilities for comics, manga, and webtoons. It is a superset of Fountain that targets storyboards.

Storyboard Package

The Storyboard/ directory contains a standalone JavaScript parser package (@fountain-plus/storyboard) that handles:

• Mangaplay format — panel-based storyboard scripts with layout tags, SFX, title cards
• Fountain format — standard screenplay parsing and round-trip conversion
• Superscript format — simplified plain-text storyboard notation
• Format detection — automatic detection of input format

Usage

import { parseScript } from '@fountain-plus/storyboard';
import { detectFormat } from '@fountain-plus/storyboard';

const ast = parseScript(scriptText);
const format = detectFormat(scriptText);

Fountain

Fountain-Plus is built on Fountain, the plain-text screenplay format created by John August and Nima Yousefi. The original Objective-C parser in the Fountain/ directory is forked from nyousefi/Fountain and released under the MIT license.
