5.1 Public Interface


5.1.1 Ordinary functions

Function: file-mime (file)

→ _mime-type_

*Arguments and Values:*

_file_—a _pathname designator_.

_mime-type_—a two-element _list_ containing both MIME type parts as _strings_ or {nil}.

*Description:*

{file-mime} returns the _mime-type_ of _file_ or {nil} if one could not be determined.

Package

file-types.

Source

access.lisp.

Function: file-tags (file &optional tag)

→ _tags_

*Arguments and Values:*

_file_—a _pathname designator_.

_tag_—a _keyword_.

_tags_—a _list_ of _keywords_ which describe properties of a given _file_.

*Description:*

{file-tags} returns _tags_ for _file_. If _tag_ is given, {file-tags} acts as a predicate that tests if _tag_ is associated with _file_. In that case {file-tags} will return {nil} unless _tag_ would be present in _tags_.

Package

file-types.

Source

access.lisp.
