Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Uncompress a CSS file

Uncompress a CSS file

Ever compress a file for the web by replacing all newline characters with nothing so it makes one nice big blob?

It is a great idea, however what about when you want to edit that file? ...Serious pain in the butt.

I ran into this today in that my only copy of a CSS file was "compressed" with no newlines.

I whipped this up and it converted back into nice human readable CSS :-)

It could be nicer, but it does the job.

Know a better way?

If you can do better, submit your command here.

What others think

There's already a tool for this: csstidy (available in Ubuntu repos)

How much space does eliminating newlines really save? I don't think it is very much at all. If you use mod_deflate with apache, then your CSS will get compressed in transit: http://www.cyberciti.biz/tips/speed-up-apache-20-web-access-or-downloads-with-mod_deflate.html

Typical case of "useless use of cat". Also, you probably mean ">", not ">>" (append).

awk '...' < somefile.css > uncompressed.css

Apart from that, I also agree bwoodacre. Removing all newlines from CSS files doesn't really make sense.

Useless use of cat? Then what in the world are you supposed to use it for?

Don't listen to these haters. There are always multiple solutions to a problem. Nice script!
