Command Line Environment

When you run Git from the command line, it runs in the environment as set up by your Shell. GUI OS X apps, however, have no knowledge about your shell - and the PATH environment can be changed in many different places. The actual environment they run in even varies depending on how the application has been started:

  • From Spotlight
  • From Finder
  • From the Dock
  • From the Terminal with the open command (or our CLI Tool)

To provide you with a configurable environment, Tower supports defining environment variables in a custom file.

To make use of this, create a PLIST XML formatted file named environment.plist in ~/Library/Application Support/com.fournova.Tower3/.

A sample to define your path could look like this:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "">
<plist version="1.0">

You can add additional key-value pairs as needed.
If your hook script needs some variable to work properly, you can introduce it like this in the environment.plist


In case you're using a special authentication mechanism, like a smartcard (e.g. Yubikey), you can set this up here too. This should be similar to:


You can either use a text editor to create a Property List or Xcode, which provides a Property List Editor.
Please note that environment variables like $HOME aren't supported in the environment.plist. Also note that using relative paths might cause problems, which is why you should consider using absolute paths.
