1.10 Working with Files and Directories: "dir.ss"
The teachpack provides structures and operations for working with files and directories:
| ||||||
| name : symbol? | ||||||
| dirs : (listof dir?) | ||||||
| files : (listof file?) |
| ||||||
| name : symbol? | ||||||
| size : integer? | ||||||
| content : (listof char?) |
| (create-dir path) → dir? |
| path : symbol? |
Turns the directory found at path on your computer into an instance of dir?.
Sample: Set teachpack to "dir.ss" and click RUN:
| > (create-dir ".") |
| (make-dir |
| '|.| |
| empty |
| (cons (make-file 'ball1.gif 1289 empty) |
| (cons (make-file 'blueball.gif 205 empty) |
| (cons (make-file 'greenbal.gif 204 empty) |
| (cons (make-file 'redball.gif 203 empty) |
| (cons (make-file 'ufo.gif 1044 empty) |
| (cons (make-file 'gif-test.ss 5811 empty) |
| empty))))))) |
Using “.” usually means the directory in which your program is
located. In this case, the directory contains no sub-directories and six
files.
Note: Soft links are always treated as if they were empty files.
