Pre-deﬁned Global Values

The system deﬁnes some values before calling your script, which you can use to make the

script’s behaviour dependent on, for example, what kind of computer you’re using. These

values (which are pretty self-explanatory) are:

•

isMac

•

isWin

•

isVST

•

isAU

•

majorVersion

•

minorVersion

•

dotVersion

•

version

The plug-in’s version number is of the form x.y.z (e.g. 2.1.4) where x is the major version

number, y is the minor version number, and z is the dot version. The ‘version’ global vari-

able contains a single value combining all three e.g. for version 2.1.4, ‘version’ is 20104.

This is useful for making your scripts backwardly compatible - by testing for the version

number and not trying to use features that were not present in a version of the plug-in

older than the version you’re testing for.

Debugging

You can use Lua’s ‘print’ function to write out information to help you track what’s going

on (or what’s not going on) in your script. Also any run-time errors, or errors in loading

the script in the ﬁrst place, are reported. In both cases, the output goes to:

Mac OS X

The system console.log. Use the standard Console utility (located in Applications/

Utilities) to view it.

Windows

The system OutputDebugString API. Use an application like Sysinternal’s DebugView to

view it.
