* Does not choke on some regexp literals containing quote characters. E.g. /'/ |

* Spaces are preserved after some add/sub operators, so they are not mistakenly |
|||
* converted to post-inc/dec. E.g. a + ++b -> a+ ++b |
|||
* |
|||
* Preserves multi-line comments that begin with /*! |
|||
* |

* |
|||
* 'isPublic' : send "public" instead of "private" in Cache-Control |
|||
* headers, allowing shared caches to cache the output. (default true) |
|||
* |
|||
* 'quiet' : set to true to have serve() return an array rather than sending |
|||
* any headers/output (default false) |
|||
* |
|||
* 'encodeOutput' : set to false to disable content encoding, and not send |
|||
* the Vary header (default true) |
|||
* |
|||
* 'encodeMethod' : generally you should let this be determined by |
|||
* HTTP_Encoder (leave null), but you can force a particular encoding |
|||
* to be returned, by setting this to 'gzip' or '' (no encoding) |
|||
* |
|||
* 'encodeLevel' : level of encoding compression (0 to 9, default 9) |
|||
* |
|||
* 'contentTypeCharset' : appended to the Content-Type header sent. Set to a falsey |
|||
* value to remove. (default 'utf-8') |
|||
* |
|||
* 'maxAge' : set this to the number of seconds the client should use its cache |
|||
* before revalidating with the server. This sets Cache-Control: max-age and the |
|||
* Expires header. Unlike the old 'setExpires' setting, this setting will NOT |
|||
* prevent conditional GETs. Note this has nothing to do with server-side caching. |
|||
* |
|||
* 'rewriteCssUris' : If true, serve() will automatically set the 'currentDir' |
|||
* minifier option to enable URI rewriting in CSS files (default true) |
|||
* |
|||
* 'bubbleCssImports' : If true, all @import declarations in combined CSS |
|||
* files will be move to the top. Note this may alter effective CSS values |
|||
* due to a change in order. (default false) |
|||
* |
|||
* 'debug' : set to true to minify all sources with the 'Lines' controller, which |
|||
* eases the debugging of combined files. This also prevents 304 responses. |
|||
* @see Minify_Lines::minify() |
|||
* |
|||
* 'minifiers' : to override Minify's default choice of minifier function for |
|||
* a particular content-type, specify your callback under the key of the |
|||
* content-type: |
|||
* <code> |
|||
* // call customCssMinifier($css) for all CSS minification |
|||
* $options['minifiers'][Minify::TYPE_CSS] = 'customCssMinifier'; |
|||
* |
|||
* // don't minify Javascript at all |
|||
* $options['minifiers'][Minify::TYPE_JS] = ''; |
|||
* </code> |
|||
* |
|||
* 'minifierOptions' : to send options to the minifier function, specify your options |
|||
* under the key of the content-type. E.g. To send the CSS minifier an option: |
|||
* <code> |
|||
* // give CSS minifier array('optionName' => 'optionValue') as 2nd argument |
|||
* $options['minifierOptions'][Minify::TYPE_CSS]['optionName'] = 'optionValue'; |
|||
* </code> |
|||
* |
|||
* 'contentType' : (optional) this is only needed if your file extension is not |
|||
* js/css/html. The given content-type will be sent regardless of source file |
|||
* extension, so this should not be used in a Groups config with other |
|||
* Javascript/CSS files. |
|||
* |
|||
* Any controller options are documented in that controller's setupSources() method. |
|||
* |
|||
* @param mixed $controller instance of subclass of Minify_Controller_Base or string |
|||
* name of controller. E.g. 'Files' |
|||
* |
|||
* @param array $options controller/serve options |
|||
* |
|||
* @return mixed null, or, if the 'quiet' option is set to true, an array |

/** |
|||
* An argument for a CLI app. This specifies the argument, what values it expects and |
|||
* how it's treated during validation. |
|||
* |
|||
* By default, the argument will be assumed to be an optional letter flag with no value following. |
|||
* |
|||
* If the argument may receive a value, call mayHaveValue(). If there's whitespace after the |
|||
* flag, the value will be returned as true instead of the string. |
|||
* |
|||
* If the argument MUST be accompanied by a value, call mustHaveValue(). In this case, whitespace |
|||
* is permitted between the flag and its value. |
|||
* |
|||
* Use assertFile() or assertDir() to indicate that the argument must return a string value |
|||
* specifying a file or directory. During validation, the value will be resolved to a |
|||
* full file/dir path (not necessarily existing!) and the original value will be accessible |
|||
* via a "*.raw" key. E.g. $cli->values['f.raw'] |
|||
* |
|||
* Use assertReadable()/assertWritable() to cause the validator to test the file/dir for |
|||
* read/write permissions respectively. |
|||
