Parsing files

func ParseFile(path string, opts ...Option) (*FileResult, error)
func WithLanguage(id string) Option

ParseFile reads path, detects its language from the basename extension, parses it, and returns a FileResult. It returns an error when the file cannot be read, the language is unsupported, or tree-sitter setup or parsing fails.

Use WithLanguage to override extension detection with a registered language ID such as go, javascript, typescript, or python.

result, err := sunset.ParseFile("script.source", sunset.WithLanguage("python"))
if err != nil {
    return err
}
defer result.Close()

Call Close exactly when the result is no longer needed. HasErrors reports whether the parsed tree contains syntax errors.
