parse_lnk()

url fl::parse_lnk ( fl::string_view content )

inline

Parse the contents of a .lnk file into a fl::url.

Format: one URL per line. Leading/trailing whitespace on each line is ignored. Blank lines and lines whose first non-whitespace character is # are treated as comments and skipped. The first non-comment, non-blank line is returned as a fl::url.

Future-compat: additional lines (metadata like sha256=..., fallback=...) are ignored by this v1 parser so older binaries keep working when future .lnk files grow richer.

See also parse_lnk_with_metadata() which returns the URL alongside the (currently unenforced) metadata fields for forward-compat callers.
