Pass - true (or an object, see the code for some options) as second - argument to get "pretty" (indented) code. - - -------------------------------- (C) --------------------------------- - - Author: Mihai Bazon - <mihai.bazon@gmail.com> - http://mihai.bazon.net/blog - - Distributed under the BSD license: - - Copyright 2010 (c) Mihai Bazon <mihai.bazon@gmail.com> - - Redistribution and use in source and binary forms, with or without - modification, are permitted provided that the following conditions - are met: - - * Redistributions of source code must retain the above - copyright notice, this list of conditions and the following - disclaimer. - - * Redistributions in binary form must reproduce the above - copyright notice, this list of conditions and the following - disclaimer in the documentation and/or other materials - provided with the distribution. - - THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDER “AS IS” AND ANY - EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE - IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR - PURPOSE ARE DISCLAIMED.
