Returns all strings extracted by either extract_literal_strings() or extract_strings_and_comments() (NOTE: be sure to call one of the aforementioned extract methods prior to strings(), or you won't get anything back). If not passed in, this returns the javascript in whatever state it happens to be in (so you can step through, and pull the data out at any time). If the option $js is passed in, this sets the javascript that will be worked on.

NOTE: if you want to specify a 'remove_comments_exceptions' option via one of these object, you must do so directly against the remove_comments() method (SEE BELOW). This is the recommended way to retain copyright notices, while still compacting out all other comments. my $squished = JavaScript::Squish->squish( $javascript ) Ĭurrent supported options: remove_comments_exceptions : array ref of regexp's Bsquish($js, remove_comments_exceptions =E )>Īny comment strings matching any of the supplied regexp's will not be removed. This is a wrapper around all methods in here, to allow you to do all compacting operations in one call. 'squish' may be exported via 'use JavaScript::Squish qw(squish) ' METHODS JavaScript::Squish->squish($js )Ĭlass method. Since JavaScript eats up bandwidth, this can be very helpful, and you can then be free to properly comment your JavaScript without fear of burning up too much bandwidth. It also provides a means by which to extract all text literals or comments in separate arrays in the order they appear. It can remove all comments, put everything on one line (semi-)safely, and remove extra whitespace.Īny one of the various compacting techniques can be applied individually, or with in any group. This module provides methods to compact javascript source down to just what is needed. # OR, to just do a few steps # my $c = JavaScript::Squish->new() Use JavaScript::Squish my $compacted = JavaScript::Squish->squish( $javascript, remove_comments_exceptions => qr/copyright/i ) or die $JavaScript::Squish::err_msg JavaScript::Squish - Reduce/Compact JavaScript code to as few characters as possible.
