Help request: how to run automatically on OS X

[jgclark]

I'd like slogger to run automatically once or twice a day on my MacBook running OS X.
Problem is that I currently have three versions of Ruby on my system including 1.8.7 and 2.2.1, niether of which slogger will run with. So I say "rvm use system" which switches to a different version, though I don't know how to find out which one (as "rvm current" just replies "system").

When I create this little script:

!/bin/bash

rvm use system ###
/Users/jonathan/Library/Scripts/slogger/slogger

It won't run from the shell, saying:

"RVM is not a function, selecting rubies with 'rvm use ...' will not work.
You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use /bin/bash --login as the command."

I know how to create and set launchd jobs; but I don't know how to set the ruby version for the created process if I can't include it in a script in this way. Thanks.

As best I can figure out from here rvm supports per-folder .ruby-version files. So putting a file named .ruby-version containing the Ruby version that you want, probably 1.9.3, in your Slogger folder should set the Ruby version for Slogger to use.

To see what version of Ruby rvm considers to be the system Ruby, running ruby --version after rvm use system should return the version details for the system ruby.

To use the rvm use system command that you want to use from the script you want to run you can change the shebang line (the line at the top of the script) to #!/bin/bash --login, or #!/bin/bash -l to invoke the bash shell as a login one, as is suggested in the output you're currently getting.

Let me know how you get on and we'll see if we can get you up and running.

Use rvm-auto-ruby instead of ruby in the launchd plist. That will pick
up the .ruby-version (use 2.0) in the slogger folder and execute with
the appropriate gem environment as created by bundle install.

Thanks, both. ruby --version gives 2.0.0p481.

It turns out I can't seem to get the launchd plist right after all. This is my attempt. Can you please spot what I'm doing wrong? Thanks.

I had the same problem, but just simply added <string>/bin/sh</string> in ProgramArguments.

This is my plist.
