We should probably return true if the extension is in PATHEXT. This should return true for EXE,COM, CMD, BAT, PS1 (if you have Powershell). It would be nice if we could inspect whatever assoc touches, so that if I add an assoc and filetype for RB, it becomes executable.

Windows doesn't really have a comparable attribute since files are "categorized" based on extension, hence .exe acting as a sort of "executable bit".

For Jim, Tomas and others, it always returns true no matter what the file extension is. Any idea why we might be getting different results? FWIW, the current IronRuby implementation returns true if the file extension is ".exe".

I have tried 1.8p27. I am running on a Windows Vista x86 machine. The file system is NTFS. I can't think of anything unusual about my machine. What are the semantic supposed to be? Most of the people I have asked get a value of true for all of the statements below, even for the File.executable? on the ttf file. puts File.exists?("C:/windows/fonts/wingding.ttf") puts File.readable?("C:/windows/fonts/wingding.ttf") puts File.executable?("C:/windows/fonts/wingding.ttf") # Prints false only for me puts File.exists?("C:/windows/notepad.exe") puts File.readable?("C:/windows/notepad.exe") puts File.executable?("C:/windows/notepad.exe") # Prints false only for me With the 1.9 binaries, File.executable? returns true only if the file extensions is something like .exe. Again, it always returns true for the people I have asked.
