[Rubycocoa-talk] Info.plist LSEnvironment does not set ENV, processInfo.environment

[Brian M. <ma...@ex...>]

Using RubyCocoa from Leopard (10.5.1) :

You can declare environment variables in a Cocoa app's Info.plist file  
like this:

	<key>LSEnvironment</key>
	<dict>
		<key>VEX</key>
		<string>acious!</string>
	</dict>

In an Objective-C app, that value carries over into the environment:

   NSDictionary *env = [[NSProcessInfo processInfo] environment];
   NSLog(@"====Here is the value of VEX in the processInfo  
environment: %@",
         [env objectForKey:@"VEX"]);

   NSDictionary *lsEnv = [[NSBundle mainBundle]  
objectForInfoDictionaryKey: @"LSEnvironment"];
   NSLog(@"====Here is the value of VEX from the Info.plist  
environment: %@",
         [lsEnv objectForKey:@"VEX"]);

processInfo environment: acious!
Feb  7 12:34:56 frex Test[1660]: ====Here is the value of VEX from the  
Info.plist environment: acious!


However, the value from Info.plist doesn't seem to make it into ENV.  
More surprisingly, it doesn't make it into the Cocoa processInfo  
environment:

     $stderr.puts "==== Here is the value of VEX in the environment:"
     $stderr.puts ENV['VEX'].inspect

     $stderr.puts "==== The value of VEX in the processInfo  
environment:"
     cocoa_env = NSProcessInfo.processInfo.environment
     $stderr.puts cocoa_env.objectForKey("VEX")

     $stderr.puts "==== The value of VEX in Info.plist:"
     plist_env =  
NSBundle.mainBundle.objectForInfoDictionaryKey("LSEnvironment")
     $stderr.puts plist_env.objectForKey("VEX")
