Hi all, Here's a funny little piece of code: http://pastebin.com/G9BG9v7j When you click on the button, it appends an instruction at the end of the file, recompiles itself, closes itself and restarts itself with the new program.
To run in the console (won't work inside DrRacket). Since I'm most probably going to use a similar code in a project, if anyone has comments on how to do things better, I'm all ears. In particular: - Is there a risk of memory leak somewhere with that kind of code? - Is there a context in which this code may break? - I'm not sure about the ports with `subprocess'. The docs say they must be closed, but since I'm using the current ones, I thought probably not. - Is `subprocess' good enough for the job? Or do I need to invoke a more low level fork? - It uses getpid from mzlib/os, which is deprecated. Is there a replacement for that? Will mzlib/os be removed in the future? (and so should I copy the relevant code into my project?) Any other comment is appreciated. Thanks, Laurent
