Question

I’m participating in one of the Code Golf competitions where the smaller your file size is, the better.

Rather than manually removing all whitespace, etc., I’m looking for a program or website which will take a file, remove all whitespace (including new lines) and return a compact version of the file. Any ideas?

Answer 1

You could use:

sed 's/\s\s+/ /g' youfile > yourpackedfile`

There is also this online tool.

You can even do it in PHP (how marvelous is life):

$data = file_get_contents('foobar.php');
$data = preg_replace('/\s\s+/', ' ', $data);
file_put_contents('foobar2.php', $data);

You have to note this won’t take care of a string variable like $bar = ' asd aa a'; it might be a problem depending on what you are doing. The online tool seems to handle this properly.
