Instructions:
* This pack contains the following compressed versions of Prototype:
moo.fx Lite, 1.4, 1.5_rc0, 1.5_rc1, 1.5 final, 1.5.1_rc2
* The root folder has an example using one of the smallest Prototype
1.5 Final forms in this package.
* prototype.js is prototype-1.5.0 (final)-ultra.js
* prototype_alt.js is prototype-1.5.0 (final)-packer (safari
2.0.4).js
Download available under the "Files" link.
Open the "protopacked files" folder.
There choose either 'original', 'formatted', or 'compressed'.
Original > The original unmodified forms of all the Prototype
versions.
Formatted > The formatted forms of all the Prototype versions.
These versions contain all the semicolons, regExp mods and
such
that make them work with the compressors.
Compressed > The compressed forms of all the Prototype versions.
Each version, except lite, has 6 different compressed
forms.
- custom: uses my custom compression (a bit slow on the
decode, I
am working on that)
- mem: compressed with the memtronics compressor
- nowhitespace: removed whitespace and comments from
the file
(Deans Packer set to "none" on the compression option).
- packer: compressed with Dean Edward's packer \w High
ASCII
compression
- packer-(safari 2.0.4) : compressed with Dean Edward's
packer \w
Normal compression
- ultra : memtronics version compressed again with my
custom
compressor.
Gzipped > The "gzipped" folders contain the gzipped forms of all
the scripts in the current folder.
Realistically, I would stick to the gzipped "nowhitespace" versions.
They have no js compression, which means no startup delay.
They are also the smallest file size (Prototype 1.5 final is 13kb).
To load gzipped files you need to go through a server side language
such as PHP.
Some have used the .gz file directly but that's not universally
supported.
* Andrea Giammarchi has created a great GzOutput.class for PHP 5.
* Use in conjunction with the nowhitespace js versions to get the
best of the gzipped goodness.

Example usage:
Good:
<script type="text/javascript" src="gz.php?src=prototype"></
script>
Bad:
<script type="text/javascript" src="prototype.gz"></script>
If you use the js "None High ASCII" compressed files usage is
like a normal js file:
<script type="text/javascript" src="prototype.js"></script>
If you use the js "High ASCII" compressed files then usage is:
<script type="text/javascript" src="protopacked.js?
load=prototype.js,prototype_alt.js"></script>
OR
<script type="text/javascript" src="protopacked.js?load=gz.php?
src=prototype,gz.php?src=prototype_alt"></script>
Safari 2.0.4/Omniweb 5.5.4 have a bug in them that causes certian
"High ASCII" text in eval()'s to error out.
For example: eval('if(/"/.¡(""));'.replace(/¡/g,'test'));
To solve this issue I created a loader, 'protopacked.js', that
detects if the browser supports
"High ASCII". If it does it loads the first High ASCII file, if not
it loads the
second None High ASCII file.
The loader is only 389bytes (less than half of 1kb).
The loader supports any filename in the same directory as itself.
Filenames are separated by a ',' (2 files are required, no spaces
between the ,'s)
I believe the bug is isolated to applications built around the webkit
version at the time.
Nightly builds of webkit have been tested successfully as far back as
Sept of 06.
High ASCII encoded files:
custom
memtronics
packer
ultra

original
formatted
nowhitespace
packer-(safari 2.04)

Troubleshooting:
If you have issues with the compressed custom/memtronics/ultra
files, try using the charset "iso-8859-1"
<script type="text/javascript" charset="iso-8859-1"
src="prototype.js"></script>
Interesting note:
The gzipped ultra compressed files are actually bigger than the
gzipped regularly compressed files.
Safari doesn't like Dean Edward's "Packer" when it removes the
semicolons after a "throw".
I had to add those back to all the encodings.
Safari didn't like prototype-1.5.0_rc0's "if(!HTMLElement..." so I had
to change it to "if(!window.HTMLElement...".
