+import ReadonlyPlugin from './plugins/readonly-plugin'; const luauCode = ` - type Person = { + type User = { + id: number, name: string, - age: number + email?: string } `; -// Method 1: Using plugin file paths -const generatedCode = await generateTypesWithPlugins( +// Method 1: Using plugin objects +const result1 = await generateTypesWithPlugins( luauCode, { useUnknown: true }, - ['./plugins/my-plugin.js', './plugins/another-plugin.js'] + [ReadonlyPlugin] ); -// Method 2: Using plugin objects directly (in-memory plugins) -import MyPlugin from './plugins/my-plugin.js'; - -const generatedCodeWithInlinePlugin = await generateTypesWithPlugins( +// Method 2: Using plugin file paths +const result2 = await generateTypesWithPlugins( luauCode, { useUnknown: true }, - [MyPlugin] + ['./plugins/custom-number-plugin.js'] ); -``` - -### With the TypeGenerator Class - -You can also apply plugins directly to a `TypeGenerator` instance: - -```typescript -import { TypeGenerator, LuauParser } from 'luats'; -import { applyPlugins } from 'luats/plugins/plugin-system'; -import MyPlugin from './plugins/my-plugin.js'; - -const parser = new LuauParser(); -const generator = new TypeGenerator({ generateComments: true }); -const ast = parser.parse(luauCode); - -// Apply plugins -applyPlugins(generator, [MyPlugin], { - typeGeneratorOptions: { generateComments: true }, - config: { preserveComments: true, commentStyle: 'jsdoc' } -}); -// Generate TypeScript with plugins applied -const typesWithPlugins = generator.generateFromLuauAST(ast); +// Method 3: Mixed approach +const result3 = await generateTypesWithPlugins( + luauCode, + { useUnknown: true }, + [ReadonlyPlugin, './plugins/custom-number-plugin.js'] +); ``` -### Using the CLI +### CLI Usage -To use plugins with the CLI, specify them in your configuration file: +Add plugins to your configuration file: ```json { + "outDir": "./types", + "include": ["**/*.lua", "**/*.luau"], "plugins": [ - "./plugins/my-plugin.js", - "./plugins/another-plugin.js" + "./plugins/readonly-plugin.js", + "./plugins/custom-number-plugin.js" ], "typeGeneratorOptions": { - "useUnknown": true + "useUnknown": true, + "includeSemicolons": true } } ``` -Then run the CLI with the config file: +Then run the CLI: ```bash -npx luats dir src/lua -o src/types --config luats.config.json +npx luats convert-dir src/lua -o src/types --config luats.config.json ``` -## Extending Plugins +### Plugin-Aware Generator + +For advanced use cases, use the `PluginAwareTypeGenerator` directly: + +```typescript +import { createPluginAwareGenerator } from 'luats/plugins/plugin-system'; +import ReadonlyPlugin from './plugins/readonly-plugin'; + +const generator = createPluginAwareGenerator({ + useUnknown: true, + includeSemicolons: true +}); -Plugins can also be used to: -- Add custom JSDoc comments or annotations -- Transform or filter generated interfaces/types -- Integrate with documentation tools (e.g., MarkdownGenerator) -- Enforce project-specific conventions +// Add plugins +generator.addPlugin(ReadonlyPlugin); + +// Generate with plugins applied +const result = generator.generateTypeScript(luauCode); +``` ## Plugin Examples -### ReadOnly Plugin +### Type Mapper Plugin -A plugin that makes all properties in generated interfaces readonly: +Map specific Luau types to custom TypeScript types: ```typescript -// readonly-plugin.ts -import { Plugin } from 'luats';

+ transformInterface: (name, properties, options) => { + // Add metadata property to all interfaces + const enhancedProperties = [...properties, { + name: '__metadata', + type: 'Record', + optional: true, + description: 'Runtime metadata' + }]; + + return { name, properties: enhancedProperties }; } }; - -export default CommentPlugin; ``` -### Custom Type Transformer +### Documentation Plugin -A plugin that maps specific types to custom implementations: +Add rich JSDoc comments: ```typescript -// type-mapper-plugin.ts -import { Plugin } from 'luats';

- - console.log(`Loaded ${plugins.length} plugins`); - return plugins; +const isValid = validatePlugin(somePluginObject); +if (!isValid) { + console.error('Invalid plugin structure'); } ``` -## Plugin Options +## Plugin Registry -The plugin hooks receive an options object with the following structure: +Manage multiple plugins with the registry: ```typescript -interface PluginOptions { - typeGeneratorOptions: TypeGeneratorOptions;
