Newbie: where is File documented?

Ruby
1

Hello,

I’m trying to work some examples (The Poignant Guide), I can’t seem to
find any official docs on the File class, found this half-finished
tutorial:

http://pleac.sourceforge.net/pleac_ruby/fileaccess.html

Is there a standard manual that would have this info?

It’s not in ruby-doc.

Thanks

Isn’t that what you were looking for?

Er, what specifically are you looking for? Not this?
class File - RDoc Documentation

You can see this same information if you have Ruby installed locally
with “ri File”.

What’s (oddly) missing from those docs is that the File class inherits
from the IO class (amonge others)
irb(main):001:0> File.ancestors
=> [File, IO, File::Constants, Enumerable, Object, Kernel]
…so when you see File.open in code, you may be confused because there
is no File.open class method documented. For those, of course, see the
IO docs (which even mention their tight association with File):
class IO - RDoc Documentation

Or is there something else that you think is missing documentation?

yeah, was looking for the read() method, it’s tucked away in IO.
