Executing shell commands on Heroku

[Chris McCann]

That app that I just deployed to Heroku (thanks to Rob's help!) uses an executable in the applications /lib directory to do some very necessary stuff.

In development this works just fine by shelling out via backticks, like:  `dostuff param1 param2`

This doesn't appear to be working on Heroku and I'm trying to dig into it.  Has anyone here done something similar?

Cheers,

Chris

Sure, you have to make sure that the lib directory is in your PATH (or relative referenced) and that they are properly committed to the repo as executable (chmod +x ). The easiest way to check on those things is to log in to the heroku shell (heroku run bash) and see what happens if you execute them manually.

Does `dostuff` provide the full path? `#{MyApplication::Application.config.root}/lib/dostuff ...`

Yes, the full path to the executable is provided.  Good suggestion to check that.  

After posting I went into bash on heroku and had a bit of a facepalm moment:  of course the executable I built for Mac OS X isn't going to run on Linux Ubuntu 14.04...disregard all!

Thanks,

Chris
