Creating a Plugin (In development)

import { Plugin, BaseNode } from "codewrangler";

export class CustomPlugin implements Plugin {
  name = "custom-plugin";

  async beforeScan(options: ScanOptions): Promise<void> {
    // Pre-scan setup
  }

  async afterRender(content: string): Promise<string> {
    // Post-render modifications
    return modifiedContent;
  }
}

Using Plugins

const pipeline = new DocumentationPipeline()
  .use(new TypeScriptDocsPlugin())
  .use(new AIAnalysisPlugin())
  .use(new CustomPlugin());

await pipeline.process({
  input: "./src",
  pattern: ".ts$",
});

Advanced Usage

AI Integration Example

import { LangChain } from "langchain";

const pipeline = new DocumentationPipeline().use(
  new LangChainPlugin({
    prompt: `
      Analyze this codebase and provide:
      1. Architecture overview
      2. Key components
      3. Improvement suggestions
    `,
    model: "gpt-4",
  })
);

Custom Template Example

const customTemplate = new Template({
  content: `
    # {{PROJECT_NAME}}
    Author: {{AUTHOR}}
    
    ## Analysis
    {{AI_ANALYSIS}}
    
    ## Components
    {{COMPONENTS}}
  `,
});
