Sublime Text 3: Set Environment Variable for plugin_host

Question

Sublime Text 3 on OSX.

I am writing a plugin that loads up a particularly poorly-written 3rd-party Python module that relies on the value of an Environment Variable to function properly (in particular, DYLD_LIBRARY_PATH).

Of course, I could set this globally, but I would love for the Sublime Plugin to be self-contained. I notice that plugins run in a child process of Sublime itself - is there any way to tell Sublime to provide the plugin_host process with a particular Environment Variable before it spins it off?

If not, does anyone know of another way to solve this problem? For performance and simplicity reasons, I would greatly prefer to have the python script be self-contained, rather than calling out to an external script that utilizes the library. Thank you.

Check out os.putenv() and os.environ for details on setting environment variables from Python. So, for your case, before importing your 3rd-party module, use something like this:

import os
os.environ['DYLD_LIBRARY_PATH'] = '/usr/lib/foo:' + os.environ.get('DYLD_LIBRARY_PATH')

import third_party
# and so on...
