Awesome!
wish i could use it on mac!
wish I could use it online!
Wish I could make a demo so I could wish I could use it online on my mac!
So much progress in so little time...!
wish i had a reason to use it!
no osx support?
what gargaj said
what tomaes said.
what v3nom said
wait, what did you just say?
am I reading it right as "j-sexy" ? :D
oh yeah! :)
Ferris>pun intended ;)
I read J-SEXE and that's enough for a thumb!
With the authors being French, I tend to read that "jSex" :p not so sexy.
COuld be a useful website.
Would it be out of the question to upload the source somewhere? When browsers and standards change the tool might need adjusting. And the Mac/whatever folks could try to port it to their preferred platform.
jsexy!
A simply wonderful tool!! There's just nothing else to touch it in its class.
Wish it was written in JS!
Genius, thanks Charles !
Do you think it can be used to improve "standard" JS ?

For standard JS / usecases I think it's better to use HTTP compression
Great job!
another coderJob i dont get like a 1%-grasp-of yet :/ man, i am legion, ehrrmm...i am lamer! ;)
too bad i didnt join adinpsz when i got that offer (due to having had joined trsi some minutes before -> trsi is 4life :D )

cb will make a talk about JsExe at DemoJS 2012 : http://demojs.org/schedule.html
New version available! Main changes from v1.0.1 to v1.0.2 :
* Multirow PNG support. No limit on input file size anymore.
* Improved PNG optimization chain based on AdvanceCOMP, DeflOpt and a better use of PNGOUT/OptiPNG. PNG color format choice has been removed.
* UI slightly improved.
Once completed I’ll release the code of JsExe, hope people will do an OSX version.
Diije> This tool is demo-oriented and is unsuitable for websites. It produces files which are not compatible with IE or older browsers, do not meet web standards, and are too slow (decompression takes more time than network transmission). For common websites, you should use regular methods such as Closure Compiler and server-side compression. That’s why JsExe is a console application and I didn’t make a point of converting it to an online service.

Great!
for the name :D
Crinkler.js =D
New version available! It includes various improvements, but the most important ones are :
* Firefox 22 support. Currently several demos released during DemoJS 2013 does not work on FF 22.
* Automatic function name mangling. Name mangling aims to redefine native browser functions with shorter names, reducing the cost of calling this functions. For instance name mangling saved 100 bytes in Grandpa 8k-demo.

Wrote the first draft of a wrapper to make it usable for using Grunt as as a task, I skipped the PNG optimizer and ByteOrder option for now - because I think they're both good default and nobody(?) wants to change them anyways.

Thanks for bringing JsExe, it just amazing how small it get's the code - I tried to do it on my own last week. Using p01s release from demojs and trying to make it smaller, didn't manage to do it - and capped at 19kb above what JsExe produced. It's just nuts :D

I can't get the latest version work with Firefox 22.0, can anybody verify it really works?
Are you sure the problem is related to JsExe? Could you send me the file you're trying to pack?
BTW thanks for your interesting contribution, mog! I definitely should install Grunt on my Windows and try "grunt-jsexe" (this name sounds so poetic !)
Only Faildows version? :(
Great tool. Thumb to counteract the idiot.
Don't know if this is a good place for bug reports, but it seems that compressing our latest craptro source with version 1.1.1 and using --compiler=best -flag will produce a rather destructive 216b file.
Using the default compiler flag will produce correct output, as will using closure compiler separately with --compilation_level ADVANCED_OPTIMIZATIONS. This might be some kind of JavaScript incompetence on my part though.

Also thumbing up for obvious reasons.
This is great! Thank you! :)

do not post about it in the comments, it will get lost.

- It takes an JS file as input parameter.
- If it helps, the JS file is optimized using an improved version of Google Closure Compiler (with no line break, better float formatting, etc).
- File byte order is reversed or not (depending on whether it improves final compression rate or not).
- It embeds the resulting file in a PNG image, choosing the best PNG format (RGB or gray).
- Then it uses the most efficient PNG optimizer tool (PNGOUT or another one).
- Then output PNG is stripped of CRC and IEND block.
- Finally the loader is appended to the output file. In the loader, V is the name of canvas element and C is the name of its 2D context. By reusing this variables in your JS code, you have an access to an existing canvas element and its 2D context and do not have to create new ones (it saves a few bytes).
For each step of the compression chain, you can force a choice by using the corresponding command line parameter. Please execute JsExe.exe for more details.
Some improvements still need to be made, for example multirow PNG support or customizable variable names. But feel free to give me any feedbacks : cb@adinpsz.org
Greetings to :
* Gasman, Daekin, p01 for their bright ideas !
* Wullon as usual,
* Google, Ken Silverman, Glenn Randers-Pehrson, Cosmin Truta for their tools.
