YUI Compressor 2.3.5, 2008-02-08
|
|
--------------------------------
|
|
|
|
+ Added a warning when more than one 'var' statement is used in a single scope.
|
|
Automatic coalescence is extremely complicated, and would be unsafe if not
|
|
done properly.
|
|
|
|
YUI Compressor 2.3.4, 2008-02-07
|
|
--------------------------------
|
|
|
|
+ Expanded the list of reserved words used by isValidIdentifier()
|
|
|
|
YUI Compressor 2.3.3, 2008-02-04
|
|
--------------------------------
|
|
|
|
+ C-style comments starting with /*! are preserved. This is especially
|
|
useful with comments containing copyright/license information.
|
|
|
|
YUI Compressor 2.3.2, 2008-02-01
|
|
--------------------------------
|
|
|
|
+ Compressing an empty JS file throws an error [SourceForge bug #1884207]
|
|
+ When a string is the first token in a function body, it was removed from
|
|
the compressed file [SourceForge bug #1884314]
|
|
|
|
YUI Compressor 2.3.1, 2008-01-30
|
|
--------------------------------
|
|
|
|
+ Added test against list of reserved words in method isValidIdentifier.
|
|
|
|
YUI Compressor 2.3, 2008-01-28
|
|
------------------------------
|
|
|
|
+ Always output a ';' at the end of a minified JavaScript file. This allows
|
|
the concatenating of several minified files without the fear of introducing
|
|
a syntax error.
|
|
+ Removed all System.exit() statements. Throw exceptions instead. This is
|
|
especially useful when running the compressor from within a J2EE container.
|
|
[SourceForge bug #1834750]
|
|
+ Transform obj["foo"] into obj.foo whenever possible, saving 3 bytes.
|
|
+ Transform 'foo': ... into foo: ... whenever possible, saving 2 bytes.
|
|
+ Added support for multi-line string literals [SourceForge bug #1871453]
|
|
+ Added support for unescaped slashes inside character classes in regexp.
|
|
+ Minor performance improvements.
|
|
+ Preserve the escaping for an octal representation of a character in string
|
|
literals [SourceForge bug #1844894]
|
|
|
|
var a = '\001';
|
|
|
|
+ CSS: Preserve comments that hide CSS rules from IE Mac:
|
|
|
|
/* Hides from IE-mac \*/
|
|
...
|
|
/* End hide from IE-mac */
|
|
|
|
+ CSS: Added support for box model hack [SourceForge bug #1862107]
|
|
|
|
div.content {
|
|
width:400px;
|
|
voice-family: "\"}\"";
|
|
voice-family:inherit;
|
|
width:300px;
|
|
}
|
|
|
|
YUI Compressor 2.2.5, 2007-10-09
|
|
--------------------------------
|
|
|
|
+ Remove line terminator after escape in string literals.
|
|
|
|
YUI Compressor 2.2.4, 2007-10-01
|
|
--------------------------------
|
|
|
|
+ Fixed the way quote characters are counted in string literals
|
|
[SourceForge bug #1804576]
|
|
+ Do not use a regular expression using non-greedy matching to remove CSS
|
|
comments (if the comment is more than 800 characters long or so, a stack
|
|
overflow exception gets thrown) Instead, use good old parsing...
|
|
+ Fix unnecessary quote escaping in string literals.
|
|
|
|
YUI Compressor 2.2.3, 2007-09-28
|
|
--------------------------------
|
|
|
|
+ Transform </script into <\/script instead of replacing all </ into <\/.
|
|
+ Fixed bug related to the shortening of hexadecimal color codes (the string
|
|
"1px solid #aabbcc" became "1px solid#abc", missing a required white space)
|
|
+ Added --preserve-strings option to specify that concatenated string literals
|
|
should never be merged.
|
|
+ Do not convert \uXXXX and \xXX escape sequences to their unicode equivalent.
|
|
|
|
YUI Compressor 2.2.2, 2007-09-27
|
|
--------------------------------
|
|
|
|
+ Fixed regression related to the optimization of the amount of escaping
|
|
in string literals and the concatenation of string literals.
|
|
+ Modified the Rhino tokenizer to handle JScript conditional comments
|
|
natively (instead of hacking around the fact that Rhino is not keeping
|
|
track of comments)
|
|
+ Transform </ into <\/ in string literals. This is especially useful if the
|
|
code is written to a script block in an HTML document. This renders the old
|
|
hack '<scr'+'ipt ...><'+'/script>' completely useless.
|
|
+ When converting decimal rgb color values to hexadecimal color values,
|
|
prepend a '0' if the value is less than 16. Otherwise, rgb(0,124,114)
|
|
for instance becomes #07c72, which is incorrect.
|
|
+ In CSS files, do not change color names into their corresponding color
|
|
codes (and vice-versa) due to the high potential of introducing bugs
|
|
(rolled back from 2.2.1)
|
|
|
|
YUI Compressor 2.2.1, 2007-09-25
|
|
--------------------------------
|
|
|
|
+ Optimize quote escaping in JavaScript string literals by using the best quote
|
|
character (' or " depending on the occurrence of this character in the string)
|
|
+ Fixed minor bug in the CSS compressor. Colors should not be shortened in
|
|
filter: chroma(color="#FFFFFF");
|
|
Otherwise, it makes the filter break in Internet Explorer.
|
|
+ In CSS files, change color names into their corresponding color codes
|
|
(and vice-versa) if that change yields any savings.
|
|
|
|
YUI Compressor 2.2, 2007-09-18
|
|
------------------------------
|
|
|
|
+ Don't obfuscate function argument named $super if it is the first function
|
|
argument listed. This is to support Prototype 1.6's heretic implementation.
|
|
+ Added support for stdin/stdout (see README for more info)
|
|
+ Shorten colors from rgb(51,102,153) to #336699 in CSS files.
|
|
+ Shorten values from 0.8em to .8em in CSS files.
|
|
+ Added support for Internet Explorer's conditional comments in JavaScript
|
|
files. Note that the presence of a conditional comment inside a function
|
|
(i.e. not in the global scope) will reduce the level of compression for the
|
|
same reason the use of 'eval' or 'with' reduces the level of compression
|
|
(conditional comments, which do not get parsed, may refer to local variables,
|
|
which get obfuscated) In any case, the use of Internet Explorer's conditional
|
|
comment is to be avoided.
|
|
|
|
YUI Compressor 2.1.2, 2007-08-31
|
|
--------------------------------
|
|
|
|
+ Added --preserve-semi option
|
|
+ Modified --line-break option
|
|
|
|
YUI Compressor 2.1.1, 2007-08-30
|
|
--------------------------------
|
|
|
|
+ Fixed missing space in CSS background:url('foo.png')no-repeat
|
|
causing a background not to appear on Internet Explorer.
|
|
|
|
YUI Compressor 2.1, 2007-08-29
|
|
------------------------------
|
|
|
|
+ Pass the --line-break option to the CSS compressor.
|
|
+ Allow the output file to overwrite the input file (with version 2.0,
|
|
in this case, the output file was always empty)
|
|
+ Remove spaces before and after '(' and ')' as in background:url('xxx');
|
|
+ Merge (if possible) string literals that are appended in JavaScript files.
|
|
This not only makes the code smaller, it makes the code faster,
|
|
but allows you to maintain some readability in your source code.
|
|
+ Handle constructs such as a + ++ b or a + + "1" (in which case the
|
|
space between the operators must be kept!) and other similar cases...
|
|
+ Pass ErrorReporter instance to the constructor of class JavaScriptCompressor
|
|
(as suggested by David Bernard for his integration of the YUI Compressor
|
|
as a maven plugin)
|
|
|
|
YUI Compressor 2.0, 2007-08-27
|
|
------------------------------
|
|
|
|
+ Switched from Rhino 1.6R6 to Rhino 1.6R7
|
|
+ Integrated Isaac Schlueter's CSS compressor.
|
|
+ Refactored code to make it easier to use the compressor from a servlet
|
|
environment or another Java app (no need to pass in file names anymore)
|
|
+ Output a white-space character after 'throw' only when necessary.
|
|
+ Output a white-space character after 'break' and 'continue' when followed
|
|
by a label.
|
|
|
|
YUI Compressor 1.1, 2007-08-20
|
|
------------------------------
|
|
|
|
+ Java source now in package com.yahoo.platform.yui.compressor
|
|
+ Added --line-break option that adds a line feed character after each
|
|
semi-colon character (may help debugging with the MS Script debugger)
|
|
+ Added support for missing JavaScript features (get, set, const)
|
|
+ Do not show the entire stack trace when the input file cannot be found.
|
|
+ Removed the randomization of obfuscated symbols. When compressed code is
|
|
checked in CVS, unchanged files would otherwise end up being versioned.
|
|
+ Added web-based front-end to the YUI Compressor as part of the dist package.
|
|
+ Added a public entry point that makes the YUI Compressor easy to integrate
|
|
with an already existing Java application.
|
|
+ Simplified code by using the same parsing routines used to build the symbol
|
|
tree while looking for undeclared symbols.
|
|
+ Count how many times each identifier is used, and display a warning when an
|
|
identifier seems to be unused (code cannot safely be removed automatically)
|
|
+ Remove ';' when followed by a '}'. This yields an additional ~1.5% savings
|
|
on yahoo-dom-event.js compared to the JSMin version.
|
|
+ Output a white-space character after 'return' and 'case' only when necessary.
|
