NAME
CSS::Squish - Compact many CSS files into one big file
SYNOPSIS
use CSS::Squish;
my $concatenated = CSS::Squish->concatenate(@files);
DESCRIPTION
This module takes a list of CSS files and concatenates them, making sure
to honor any valid @import statements included in the files.
Following the CSS 2.1 spec, @import statements must be the first rules
in a CSS file. Media-specific @import statements will be honored by
enclosing the included file in an @media rule. This has the side effect
of actually *improving* compatibility in Internet Explorer, which
ignores media-specific @import rules but understands @media rules.
It is possible that feature versions will include methods to compact
whitespace and other parts of the CSS itself, but this functionality is
not supported at the current time.
METHODS
CSS::Squish->concatenate(@files)
Takes a list of files to concatenate and returns the results as one big
scalar.
CSS::Squish->concatenate_to($dest, @files)
Takes a filehandle to print to and a list of files to concatenate.
"concatenate" uses this method with an "open"ed scalar.
BUGS AND SHORTCOMINGS
At the current time, comments are not skipped. This means comments
happening before @import statements at the top of a file will cause the
@import rules to not be parsed. Make sure the @import rules are the very
first thing in the file (and only one per line).
Only direct @import loops (i.e. where a file imports itself) are checked
and skipped. It's easy enough to get this module in a loop. Don't do it.
As of now, server-relative URLs (instead of file-relative URLs) will not
work correctly.
