=head1 NAME
CSS::Minifier - Perl extension for minifying CSS
=head1 SYNOPSIS
To minify a CSS file and have the output written directly to another file
use CSS::Minifier qw(minify);
open(INFILE, 'myStylesheet.css') or die;
open(OUTFILE, 'myStylesheet.css') or die;
minify(input => *INFILE, outfile => *OUTFILE);
close(INFILE);
close(OUTFILE);
To minify a CSS string literal. Note that by omitting the outfile parameter a the minified code is returned as a string.
my minifiedCSS = minify(input => 'div {font-family: serif;}');
To include a copyright comment at the top of the minified code.
minify(input => 'div {font-family: serif;}', copyright => 'BSD License');
The "input" parameter is manditory. The "output" and "copyright" parameters are optional and can be used in any combination.
=head1 DESCRIPTION
This module removes unnecessary whitespace from CSS. The primary requirement developing this module is to not break working stylesheets: if working CSS is in input then working CSS is output. The Mac/Internet Explorer comment hack will be minimized but not stripped and so will continue to function.
This module understands space, horizontal tab, new line, carriage return, and form feed characters to be whitespace. Any other characters that may be considered whitespace are not minimized. These other characters include paragraph separator and vertical tab.
For static CSS files, it is recommended that you minify during the build stage of web deployment. If you minify on-the-fly then it might be a good idea to cache the minified file. Minifying static files on-the-fly repeatedly is wasteful.
=head2 EXPORT
None by default.
Exportable on demand: minifiy()

=head1 NAME
JavaScript::Minifier - Perl extension for minifying JavaScript code
=head1 SYNOPSIS
To minify a JavaScript file and have the output written directly to another file
use JavaScript::Minifier qw(minify);
open(INFILE, 'myScript.js') or die;
open(OUTFILE, '>myScript-min.js') or die;
minify(input => *INFILE, outfile => *OUTFILE);
close(INFILE);
close(OUTFILE);
To minify a JavaScript string literal. Note that by omitting the outfile parameter a the minified code is returned as a string.
my minifiedJavaScript = minify(input => 'var x = 2;');
To include a copyright comment at the top of the minified code.
minify(input => 'var x = 2;', copyright => 'BSD License');
To treat ';;;' as '//' so that debugging code can be removed. This is a common JavaScript convention for minification.
minify(input => 'var x = 2;', stripDebug => 1);
The "input" parameter is manditory. The "output", "copyright", and "stripDebug" parameters are optional and can be used in any combination.
=head1 DESCRIPTION
This module removes unnecessary whitespace from JavaScript code. The primary requirement developing this module is to not break working code: if working JavaScript is in input then working JavaScript is output. It is ok if the input has missing semi-colons, snips like '++ +' or '12 .toString()', for example. Internet Explorer conditional comments are copied to the output but the code inside these comments will not be minified.
The ECMAScript specifications allow for many different whitespace characters: space, horizontal tab, vertical tab, new line, carriage return, form feed, and paragraph separator. This module understands all of these as whitespace except for vertical tab and paragraph separator. These two types of whitespace are not minimized.
For static JavaScript files, it is recommended that you minify during the build stage of web deployment. If you minify on-the-fly then it might be a good idea to cache the minified file. Minifying static files on-the-fly repeatedly is wasteful.
=head2 EXPORT
None by default.
Exportable on demand: minifiy()
