Working files and directories in Emacs
Much inspired by @magnars’s excellent s.el and dash.el, f.el is a modern API for working with files and directories in Emacs.
Example
(let* ((dir
(f-join "~" "tmp" "dir"))
(foo-file
(f-expand "foo.txt" dir))
(bar-file
(f-expand "bar.txt" dir)))
(unless (f-directory? dir)
(f-mkdir dir))
(f-write foo-file "SOME ")
(f-write foo-file "CONTENT" 'append)
(f-write bar-file "MORE...")
(-map
(lambda (file)
(message
"File: %s, content: '%s', size: %d"
(f-relative file dir)
(f-read file)
(f-size file)))
(f-files dir))
(message "Total size of all files in %s: %d" dir (f-size dir)))The output will be:
File: bar.txt, content: 'MORE...', size: 7
File: foo.txt, content: 'SOME CONTENT', size: 12
Total size of all files in ~/tmp/dir: 19
