close!clj
(close! {:keys [stream close-fn] :as file})Close a stream and optionally call its close-fn function if it's present.
Close a stream and optionally call its close-fn function if it's present.
delete-filecljmultimethod
Deletes a file with any implementation.
Deletes a file with any implementation.
exists?cljmultimethod
Returns true if filename exists.
Returns `true` if filename exists.
file-readerclj
(file-reader filename)(file-reader filename options)Returns a file reader.
Returns a file reader.
file-writerclj
(file-writer filename)(file-writer filename options)Returns a file writer.
Returns a file writer.
get-file-typeclj
(get-file-type filename)(get-file-type filename _ & _)Dispatch function for files IO multimethods.
Dispatch function for files IO multimethods.
input-streamclj
(input-stream filename)(input-stream filename options)Returns an input-stream for plain or compressed file.
Returns an input-stream for plain or compressed file.
list-dirscljmultimethod
Returns a seq of directories with provided path as prefix.
Returns a seq of directories with provided path as prefix.
list-filescljmultimethod
Returns a seq of filenames with provided path as prefix.
Returns a seq of filenames with provided path as prefix.
mk-input-streamcljmultimethod
Returns an input stream with any implementation.
Returns an input stream with any implementation.
mk-output-streamcljmultimethod
Returns an output stream with any implementation.
Returns an output stream with any implementation.
output-streamclj
(output-stream filename)(output-stream filename options)Returns an output-stream for plain or compressed file.
Returns an output-stream for plain or compressed file.
register-file-pred!clj
(register-file-pred! file-type file-pred)Registers a new file type with a file predicate.
Extends the dispatch function of the multimethods with your own implementation.
Example: (register-file-pred! :my-filetype (fn [filename] (clojure.string/starts-with? (str filename) "myprotocol://")))
(defmethod mk-input-stream :my-filetype [filename & [options]] ;; ... {:stream ...})
The code above is sufficient to get all reading function for free on your custom protocol, given that mk-input-stream works correctly.
Registers a new file type with a file predicate.
Extends the dispatch function of the multimethods with your own
implementation.
Example:
(register-file-pred!
:my-filetype
(fn [filename]
(clojure.string/starts-with? (str filename) "myprotocol://")))
(defmethod mk-input-stream :my-filetype
[filename & [options]]
;; ...
{:stream ...})
The code above is sufficient to get all reading function for free on your
custom protocol, given that mk-input-stream works correctly.sizeofcljmultimethod

Probe the size of the target files/folder. Should not load dataset in memory.
unzip-filecljmultimethod
Unzip the targeted file to the current directory.
If not a Zip file, yield nil.
Unzip the targeted file to the current directory. If not a Zip file, yield `nil`.
