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

From: kimura w. <ki...@us...> - 2008-02-09 00:56:35

Hi,

It works for me on 10.5.1.
LSEnvironment is available for apps launched via Launch Service. 
- double-click in Finder
- launch with "open" command

LSEnvironment is not available without Launch Service.
- "Run" on Xcode
- execute YourApp.app/Contents/MacOS/YourApp directly

[Rubycocoa-talk] Draft chapter of RubyCocoa book

From: Brian M. <ma...@ex...> - 2008-02-08 21:17:18

I'm writing a book on RubyCocoa for the Pragmatic Bookshelf, publisher
of many fine titles. <http://www.pragprog.com/titles>

I'm ready for people to take a look at a chapter. It's actually the
second chapter. The preceding introduction, covering prerequisites,
the general plan of the book, its goals, what "Cocoa" is, etc. -- that
will probably be written last.

But to orient yourselves:

- I assume you know Ruby, but nothing about Objective-C, Cocoa, or
building apps on the Mac.

- Rather than build the exposition from the outside-in, teaching you
first how to draw user interfaces, I'm working from Ruby up. I start
with Ruby, then begin adding Cocoa ideas and tools onto it.

- Especially in the beginning of the book, I want people to start
changing code and seeing what happens. Might as well take advantage of
Ruby's fast edit-run loop.

The chapter and associated code are distributed as a disk image: http://www.exampler.com/tmp/drafts/draft-of-2008-02-08.dmg

What am I looking for? Don't bother with typos, misspellings, grammar,
awkwardly-placed figures, and the like: those will all get changed
later. I'm interested in two things:

1. Did the approach work for you? Did this chapter flow in a pleasing
and sensible way? Is there information inexplicably missing?

2. Where did you get confused or stuck, in either the text or the "try
this yourself" sections? Why? What would have helped?

Thanks.

Further announcements will go only to the mailing list:

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

From: Brian M. <ma...@ex...> - 2008-02-07 19:01:57

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"]);


Feb  7 12:34:56 frex Test[1660]: ====Here is the value of VEX in the  
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")
