Constructor Details

#initialize(options = {}) ⇒ JavaScriptCompressor

Creates a new YUI::JavaScriptCompressor for minifying JavaScript code.

Options are:

:charset

Specifies the character encoding to use. Defaults to "utf-8".

:line_break

By default, JavaScript will be compressed onto a single line. Use this option to specify the maximum number of characters in each line before a newline is added. If :line_break is 0, a newline is added after each JavaScript statement.

:munge

Specifies whether YUI Compressor should shorten local variable names when possible. Defaults to false.

:optimize

Specifies whether YUI Compressor should optimize JavaScript object property access and object literal declarations to use as few characters as possible. Defaults to true.

:preserve_semicolons

Defaults to false. If true, YUI Compressor will ensure semicolons exist after each statement to appease tools like JSLint.
