func DepKey ¶

func DepKey(raw string) string

DepKey normalizes a Python module path to its top-level package name (the PyPI dep key, in most cases).

"requests"            -> "requests"
"requests.adapters"   -> "requests"
"flask.helpers"       -> "flask"
".local"              -> ""    (relative)
"..pkg.x"             -> ""    (relative)
""                    -> ""

Limitation: namespace packages where the top-level differs from the PyPI distribution (e.g. `google.cloud.storage` from `google-cloud-storage`) need consumer-side mapping. depusage emits the dotted top-level only.

func Extract ¶

func Extract(body []byte, opts extract.Options) (extract.Result, error)

Extract runs the Python import pass over body.

func IsRelative ¶

func IsRelative(raw string) bool

IsRelative reports whether the module path uses leading-dot relative notation (e.g. `.x`, `..y.z`, `.`).
