#ifdef for .cfg files? [message #677492]

Is there any way to conditionally enable entries in a .cfg file? e.g. something along the lines of the following would be useful:

#ifdef ENABLE_LOAD_MONITORING
Load = xdc.useModule('ti.sysbios.utils.Load');
Load.taskEnabled = true;
Load.hwiEnabled = false;
#endif

with ENABLE_LOAD_MONITORING defined in e.g. the build settings or some external file.

Regards,
Brian

..cfg files are JavaScript files interpreted by the Rhino JavaScript
engine.

So, while there is no #ifdef, you have the full power of JavaScript
if/then/else as well as the ability to get environment variables or read
files via java.

For example,
if (java.lang.System.getenv("ENABLE_LOAD_MONITORING")) {
:
}

See http://rtsc.eclipse.org/docs-tip/The_XDCscript_Language and
http://rtsc.eclipse.org/docs-tip/The_XDCscript_Language#The_environment__and_arguments_objects
for details.
