Fix luatex error message pop-up
When the luatex engine encounters an error, writeLaTeX will not show the erroneous line, nor will it show a pop-up menu with the error message. Instead one has to download the log file and read it. I guess it should be easy to fix: it's probably the luatex error message syntax which is not recognized by writeLaTeX. Please do fix it :-)
Thanks for reporting this. You are right that our log parser doesn’t currently understand LuaLaTeX errors. We will upgrade it as soon as we can.

I am still very much surprised that this hasn't been fixed after 2 years! LuaLaTeX has since been released and incorporates many useful features so that many users would want it to be their primary TeX engine. I was seriously considering getting a bunch of Pro subscriptions for my team but I can't really do it if LuaLaTeX support is lacking...

Here is the error message you get whenever luatex encounters an error:
==> Fatal error occurred, no output PDF file produced!
Besides the fact that I need to download and open the log file zillions of times, the term "fatal error" is a bit scary…
