# @aitube/clap

*Types and helpers to manipulate .clap files*

## Introduction

This library is the reference implementation of [OpenClap](https://github.com/jbilcke-hf/OpenClap-Format) for NodeJS and browser environments.

**OpenClap** is a prompt container file format that was initially created for my AiTube.at project. I am also using it in my other AI demos, and I think you should use it, too!

## Installation

To install the package, run the following command (`yaml` is a peer dependency):

```bash
npm install @aitube/clap yaml
```

## Getting Started

  ClapEntityTimbre,
  ClapEntityAudioEngine,
  ClapSegmentFilteringMode,
  ClapVoice,
  ClapHeader,
  ClapMeta,
  ClapSceneEvent,
  ClapScene,
  ClapSegment,
  ClapEntity,
  ClapProject, 
  ClapImageRatio,

  ClapInputFieldNumber,
  ClapInputFieldString,
  ClapInputFieldBoolean,

  ClapWorkflowEngine,
  ClapWorkflowCategory,
  ClapWorkflowProvider,
  ClapWorkflow,

// defaults
  defaultImageRatio,

  // factories
  newClap,
  newEntity,
  newSegment,
  newWorkflow,

  // main input/output handlers
  parseClap,
  serializeClap,
  fetchClap,
  updateClap,

  // utilities

  dataUriToBlob,
  clapToDataUri,

  // helpers
  buildEntityIndex,
  filterAssets,
  filterSegmentsByCategory,
  generateClapFromSimpleStory,
  getEmptyClap,
  removeGeneratedAssetUrls,

  // sanitizers
  sanitizeEntities,
  sanitizeEntity,
  sanitizeMeta,
  sanitizeSegment,
  sanitizeSegments,
  sanitizeWorkflow,
  sanitizeWorkflows,
} from "@aitube/clap"


// fetch a Clap file
const res = await fetch("https://..../file.clap")
const file = await res.blob()

// open the Clap file
const clap: ClapProject = await parseClap(file)

// perform arbitrary changes in the project

clap.segments.at(64).assetUrl = await generateVideoWithAI(....)

const segment: ClapSegment = clap.segments.at(42)
segment.prompt = "a camel in the desert, medium-shot, award-winning, 4k, Canon EOS"

const storyboards = clap.segment.filter(s => s.category === ClapSegmentCategory.IMAGE)

// save the Clap file
const newFile: ClapProject = await serializeClap(clap)
```
