^ Path Separator and Windows
173032 [justinjohnso] Using ruby 1.8.2 on Windows XP, the path separator used for things like
+ 173035 [bob_showalte] "correct" is debatable, since the Windows API accepts / as a separator.

|   | + 173059 [perrin apoth] Depending on how you look at it, I think it was either poor planning or
|   | + 173146 [jkelliemille] To show my age :-), I think the reason is historic.  The original DOS file

|   | | + 173285 [rosco roscop] Well, if I have to write my code to check path separators and work around
|   | + 173275 [rosco roscop] I doubt it - they'd probably need to rewrite it (again).

+ 173036 [halostatue g] Unless you're interacting with external programs, you don't need it to.
+ 173037 [langstefan g] For ruby, "/" *is* the correct path separator. AFAIK, ruby
| 173270 [djberg96 gma] Except that not all Windows functions accept '/' for a path separator.
