Solution: Clear a directory

Here is a possible solution to the task.

Code

mkdir 'cache';
spurt 'cache/a.tmp', '1';
spurt 'cache/b.tmp', '2';

.unlink for 'cache'.IO.dir;
rmdir 'cache';

say 'cache'.IO.e;

🦋 You can find the source code in the file clear-a-directory.raku.

Output

False

Comments

rmdir only removes an empty directory, so the files have to go first. 'cache'.IO.dir lists the entries, and .unlink for … deletes each one.
With the directory now empty, rmdir removes it. The final .e test reports False, confirming that cache is gone.
