Bases: object

Retry transient HTTP failures and fall back to mirrored support data.

dataFetcher.fetch_support_data(rel: str, progressbar: bool = False) → str

Fetch a support data file using retry-hardened HTTP downloads.

dataFetcher.find_local_support_data() → Path | None

Return the path to the local supportData directory if running from a cloned repo, otherwise return None.

Works whether running from source (src/) or from built modules (dist3/Basilisk/).

dataFetcher.get_path(file_enum: Enum) → Path

Return a filesystem path for the requested supportData file.

If running from a local Basilisk repo, the file is returned directly from supportData/. Otherwise, it is fetched or retrieved from the Pooch cache.

dataFetcher.local_support_path(rel: str) → Path | None

Return the local filesystem path for a registry-style key, if available.

dataFetcher.tag_exists(tag_url: str) → bool

Return True if the given GitHub tag URL exists.

Cached so repeated calls never trigger additional network requests.
