Core trait for transpiler plugins

Implement this trait to create custom transpilers that integrate with Batuta’s pipeline.

Required Methods

fn metadata(&self) -> PluginMetadata

Get plugin metadata

fn transpile(&self, source: &str, language: Language) -> Result<String>

Transpile source code to Rust

Arguments

• source - Source code to transpile
• language - Source language

Returns

Rust code as a String

Provided Methods

fn initialize(&mut self) -> Result<()>

Initialize the plugin

Called once when the plugin is loaded. Use this for setup tasks like:

• Loading configuration
• Initializing caches
• Validating dependencies

fn transpile_file(&self, path: &Path, language: Language) -> Result<String>

Transpile a file

Default implementation reads the file and calls transpile(). Override for custom file handling (e.g., imports, multi-file projects).

fn validate(&self, _original: &str, _transpiled: &str) -> Result<()>

Validate transpiled output

Optional validation hook. Override to add custom validation logic.

fn cleanup(&mut self) -> Result<()>

Cleanup resources

Called when the plugin is unloaded or the pipeline completes.
