:if the file does not exist, it should not be created. it would be nice if the code would fail gracefully if the file is missing, but i don't think this is necessary. it is just a code snippet to solve a particular problem. i'd expect developers to adapt the code if their situation is slightly different. [[Ensure that a file exists]] solves that part for example. no need to repeat it here.--[[User:EMBee|eMBee]] 03:07, 17 February 2012 (UTC)

== Follow symlinks ==
FWIW, following symlinks seems like a really bad idea. It's fine in the context of something like Emacs (which sounds like a possible motivation) with a feature to visit files under their "real" names, but in those cases the user is usually aware of the new name via the UI (as in getting a different buffer name). But for a script this is just wrong, since you get a script which works in a way that can change in the presence of symlinks -- and the whole point of symlinks is to get things to work even when a file is elsewhere. I think that it would be better to simplify this by ignoring symlinks completely, and introduce a separate task for resolving symlinks. --[[User:Elibarzilay|Elibarzilay]] ([[User talk:Elibarzilay|talk]]) 21:01, 17 May 2013 (UTC)
