If you alreadu have a string and you want to print it in a way that they compiler can evaluate it back, you can just use #printString on the string. printString calls storeOn:, which doubles any contained quotes and puts quotes around. This is called when doing a "print it", too. So one gets a bit confusted when doing a "print it" of 'hello' printString... it's called twice :-) Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

Escape strings for compiler

by Norbert Hartl

Hi, I tried to compile a method that returns a string. Is there a method to escape a string in a way that the compiler treats it as a string and not as code? thanks, Norbert

I would not try... in theory it would work with a core image, but loading 411 updates is far too slow. The idea is that one loads the code in a new image. People learned over the years that this is good to do anyway, as this tests that you actually *can* load your code. e.g. you don't realy on objects in the image that you created years ago but that you lost the setup code for. This is important even independend of updating from 1.0 to 1.1 > 2) How do I make a "one-click" image that will start my app when clicked? > You can just exchange the image file in the directory Contents/Resources On the mac, you need to use "show package contents" to open the browser on the .app directory.
