Functions

func Detect 

func Detect(name, contentType string, data []byte) string

Detect identifies the document type from magic bytes, falling back to contentType header and file name extension.

Types

type Result 

type Result struct {
	Type      string // detected MIME type, e.g. "application/pdf", "text/html"
	Text      string // extracted plain text
	Extracted bool   // true when a type-specific extractor produced the text (false = pass-through)
}

Result holds the outcome of document detection and extraction.

func Extract 

func Extract(name, contentType string, data []byte) (*Result, error)

Extract detects the document type and returns extracted plain text. Returns an error for empty data and for known-binary types that fail extraction. Unknown binary types return a descriptive error so the caller can skip the document.
