Anyone want to test a webkit nightly? I don't have a desktop machine handy tight now to test on :( Or even just a bug report at bugs.webkit.org Thanks :)

Just tried it, crashes in the exact same way: 1. Hitting "Compile" does whatever it should do successfully. 2. Then hitting "Open PDF" opens a new tab which stalls out and crashes I would almost say its actually a PDF thing that is crashing Safari vs a JS thing. At least, that's what has happened consistently on my machine with latest Safari and WebKit nightly. Edit: However, taking the generated PDF from Chrome and…

Yup, that is for sure it. I took the Chrome generated PDF, turned it into a data URL, then copy-pasted the data URL into Safari's URL bar. Crash.

Drag and dropping the file itself into Safari, works fine.

Nice debugging, not a fan of making blanket assumptions when something isn't working as expected.

Just wanted to comment that this works better in Internet Explorer 10, documents seemed to compile significantly faster than on Chrome. Running Windows 8x64, for reference.

Really?! I didn't expect that! (I don't run Windows, and so I didn't try it in IE.) Good to know, thanks!

Wow, I really would like to know how this was achieved... Note that it is somewhat broken for me: http://imgur.com/twIG75m

Wow is indeed the best way to describe this project!

From what I see, the main work horse is this 250k "binary": https://raw.github.com/manuels/pdftex.js/master/release/pdft...

This webworker script in combination with a .fmt (latex format file) generates the PDF. All in JS. @manuels__ this is awesome!

Thanks ivan_ah! I really didn't expect so much positive response!

Yes, the main work is done in the webworker (~250kb) + the tex format file latex.fmt (~700kb)
