Returns a set of SPDX expressions (Strings) for dir. See dir->expressions-info for details.

Returns an expressions-info map for dir (a String or File, which must refer to a readable directory), or nil if or no expressions were found.

The optional opts map has these keys: * include-hidden-dirs? (boolean, default false) - controls whether hidden directories (as defined by java.io.File.isHidden()) are included in the search or not. * include-zips? (boolean, default false) - controls whether zip compressed files found in the directory are recursively included in the scan or not

Note: logs and ignores errors (XML parsing errors, ZIP file errors, etc.)

Returns a set of SPDX expressions (Strings) for f. See file->expressions-info for details.

Returns an expressions-info map for f (an InputStream or something that can have an clojure.java.io/input-stream opened on it), or nil if no expressions were found.

If an InputStream is provided, it is the caller’s responsibility to open and close it, and a filepath associated with the InputStream must be provided as the second parameter (it is not required for other types of input).

Initialises this namespace upon first call (and does nothing on subsequent calls), returning nil. Consumers of this namespace are not required to call this fn, as initialisation will occur implicitly anyway; it is provided to allow explicit control of the cost of initialisation to callers who need it.

Note: this method may have a substantial performance cost.

Returns true if the given file-like thing (String containing a filename, File, ZipEntry) is a probable license file, false otherwise.

Returns all probable license files in the given directory, recursively, as a set of File objects. dir may be a String or a File, either of which must refer to a readable directory.

The optional opts map has these keys: * include-hidden-dirs? (boolean, default false) - controls whether hidden directories (as defined by java.io.File.isHidden()) are included in the search or not.

Returns a set of SPDX expressions (Strings) for zip. See zip->expressions-info for details.

Returns an expressions-info map for zip (a String or File, which must refer to a ZIP-format compressed file), or nil if no expressions were found.

Throws various Java IO exceptions if the file is not a valid ZIP-format file.
