I have a LaTeX file that executes an external shell command to get some information; this works on my local machine but fails on Overleaf. That's okay, not a big deal—if I can wrap the code in an if-then conditional that checks if it's executing on Overleaf.
Problem: how can I make my LaTeX code check if being run on Overleaf?
Clarification added 2017-07-31: I already know how to test for shell escapes, and conditionalize my code appropriately. The problem is not whether shell escapes work; the problem is really about testing for Overleaf versus other environments.

surely you don't want o know if it's on overleaf but if shell escape is enabled?, which you can test for the integer value ofpdfshellescapeorshellescapeor in luastatus.shell_escapedependin on the tex flavour in use.

No; in fact, shell escapes do work, and I already test for that in my code. But the command involves getting information using git, and this works differently in my local environment versus in Overleaf. I have given up trying to figure out why the command fails. I just want to skip the whole thing when running on Overleaf.

Jul 31 '17 at 15:01
oh in that case you could shell escape and look at the environment variables, surely overleaf must have some environment variable set with a distinguished value?

That would work, but I have not found anything relevant in their documentation so far. I was hoping someone here would have already done something like this and knew the answer.

I think the simplest solution is to determine the home path used by Overleaf and test against that. It's unlikely to match your local home path.
To find Overleaf's home path:
documentclass{article}
makeatletter
begingroupendlinechar=-1relax
everyeof{noexpand}%
edefx{endgroupdefnoexpandhomepath{%
@@input|"kpsewhich --var-value=HOME" }}x
makeatother
begin{document}
HOME: texttt{homepath}.
end{document}
Then copy the resulting path and test against that:
documentclass{article}
makeatletter
begingroupendlinechar=-1relax
everyeof{noexpand}%
edefx{endgroupdefnoexpandhomepath{%
@@input|"kpsewhich --var-value=HOME" }}x
makeatother
defoverleafhome{/home/whatever}% change as appropriate
begin{document}
ifxhomepathoverleafhome
Overleaf.
else
Not Overleaf.

I used this approach. Based on some testing, that path on Overleaf appears to be/home/wl. Thank you very much for this solution.

Aug 7 '17 at 20:00
Addendum: I examined other environment variables, per David Carlisle's comments at the top. Unfortunately, no other variable other thanHOMEseemed safe enough to use (in the sense that I couldn't be sure a collaborator would get the expected behavior if the used the files in their local environment).

No; in fact, shell escapes do work, and I already test for that in my code.
