I have created a new version of the patch that adds an option to specify the character set (eg. UTF8) used by the input file. You can download it from: http://paiq.nl/custom_rhino_charset.diff

Using the current Rhino HEAD gives some runtime problems you will want to avoid, try an older version. I used:

Apart from that, compilation and usage is the same; except for the added optional '-E <encoding>' parameter.

Hi,

Nice work! I'll have to give ShrinkSafe a try. How does it compare to JSMin or the YUI Compressor?

- rob

Shrinksafe is a really good tool, no doubt.
But I'm bothered by the fact, that the new Update for IE these days, still has the same problems with some java webappliactions like before.
Hope the next version will support it completely, so that everyone can admire my java features compressed with ShrinkSafe.

In my web project, I often use String concatenations.
It's because I use innerHTML a lot to change the content of the screen.
Using innerHTML is faster to run and to code than DOM methods.
To help keep the source clean, I often do things like this:

html +=
"<li class='pressable'>" +
"<a onclick='return Screen.pressAutoRefresh()' href='#'>" +
"<img width='22' height='22' alt='' src='icones/22/auto-refresh.png'/>" +
"</a>" +
"</li>";

The compressed result is something like this:
"<li class='pressable'>"+"<a onclick..."

Obviously, a lot of '"+"' can be removed to optimize concatenations so that the browser do not have to do useless computations.

By doing so manually, I'm often gaining from 1/3 to 1/2 of speed!
This is important.

Any chance ShrinkSafe can do that automatically?

And, by the way, I would want to include Shrink safe automatically in my Eclipse JSP project so that as soon as I modify a .js script, ShrinkSafe compress it and place it in the build folder. I've downloaded ShrinkSafe JAR and I'm now trying to do that. Do someone already done that? Any pointer to help me?

Works very well for me, now I would like to play with the different level of compression, I've read about removing carriage return as an option and not being done by default. Which parameter is that ?

The CompressorRater is a web application that lets you dynamically compare the compression levels of Dojo Shrinksafe, along with several other popular javascript compressors, both with and without the affects of additional gzip compression.

Thanks for the script. Helped me with my studies in java at university.

hi, I really like ShrinkSafe. In fact I recommended it to some of my friends. And their feedback?

"I can't remember the syntax well!"
"Its too long. I'm lazy to type in a lot of letters!".

So I decided to make a simple batch file that will do the standard compression easier. Of course, this code is modifiable to also accept the other parameters for advanced compression settings. Also, this assumes a Windows XP environment with JAVA installed. I named the batch file "ShrinkSafe.bat" by the way.

@echo OFF
cls
echo Dojo ShrinkSafe - Javascript Compression System
echo.
set /p input=What script do you wish to compress? 
set /p output=What filename do you wish to output it on? 
java -jar custom_rhino.jar -c %input% > %output% 2>&1
set name=
echo.
echo Compression done!
echo.
pause
exit

Edit: Oh and a request to the developers perhaps:

When I compress my scripts, it always produces 2 blank newlines at the bottom. Is it just me? It's still 2 whitespaces right?

Hi guys,
Could someone tell me how to do the following correctly?

java -jar custom_rhino.jar -c infile1.js infile2.js infile3.js > outfile.js 2>&1

That is spcefiy more than one input file and also to strip newline characters as you can on the web interface.

Thanks!

...great info and heads up sharing how you guys do this and what tools you use, greatly appreciate it.

Nice.

Hi, it is working fine for me. What are the issue you have encounter?

Great work ShrinkSafe

Thank You
Brent

It seems that URL in the article are wrong, diff and jar are in http://svn.dojotoolkit.org/util/trunk/shrinksafe/

Thanks

Ive read that Dojo compressor doesn’t like that the variable event is redeclared or the compressed code will produce errors...

Thanks,

FYI, if you still wish to compress names of local variables (non-destructive compression) AND change public API names too (destructive compression, or obfuscation) you can use another Rhino-based tool - JavaScript Obfuscator from Stunnix. It has a GUI too, can process code inside HTML, and can process several file at once (thus it's much faster).

thanks for sharing. It works great for me!
