Environment variables are strings of information, such as a specific hard drive, file name, or file path, set through a shell (for example, in Terminal on a Mac OS X system) that is associated with a symbolic name (that you determine). This information is stored in a hidden file. Each time you launch Shake, the operating system and the Shake application look at the hidden file to set the environment variables. In other words, defining environment variables is the equivalent of setting user-defined system preferences. As a simple example, you can set an environment variable that specifies a folder that Shake scans (on launch) for additional fonts used by the Text or AddText node. To set environment variables on a Mac OS X system, create and edit a ".plist," or property list, file. Using the .plist sets variables for Shake whether it is launched from the Terminal or from the Shake icon. Using the above example of a font folder, to instruct Shake to read the /System/Library/ Fonts folder, set the following environment variable in your .plist file: NR_FONT_PATH /System/Library/Fonts Another way to define environment variables is to use the setenv command in a .tcshrc (enhanced C shell resource) file. Each time the Terminal is launched, the .tcshrc file is read. The environment variables defined by the .tcshrc file are only read by Shake when launched from the Terminal. Using the above example of a font folder, to instruct Shake to read the /System/Library/ Fonts folder, set the following environment variable in your .tcshrc file: setenv NR_FONT_PATH /System/Library/Fonts Note: The .tcshrc file can be used on all Shake platforms (Mac OS X and Linux). A common use for a user's personal .plist or .tcshrc file is to define commonly used aliases for commands. As a simple example, you can set an environment variable to launch Shake from the Terminal. An alias in the command line is not the same as an alias on the Macintosh operating system. In the OS, an alias merely points to another file. In the command line, you create an alias to assign your own name to a command. Note: If you do not have environment variables set on your Mac OS X system, you can still launch Shake from the Terminal by typing the complete path to Shake: /Applications/Shake4/shake.app/Contents/MacOS/shake 394 Chapter 14 Customizing Shake
