Constructor Details

#initialize(path, cygdrive_prefix = '/cygdrive/') ⇒ Path

Create a new Path from path.

> winpath = Windirs::Path.new 'C:\Users\noah\Desktop'
> nixpath = Windirs::Path.new '/bin/ls'
> cygpath = Windirs::Path.new '/cygdrive/c/Users/noah/Desktop'

You probably don’t need to know the rest of this: cygdrive_prefix defaults to ‘/cygdrive/’, and is used to extract drive letters from Cygwin-ish looking paths. If you know will not be using Cygwin paths, you may wish to assign this to ”. If your cygdrive path prefix is something else, you should assign this appropriately. See cygwin.com/cygwin-ug-net/using.html#cygdrive for details. Note that we are using a trailing slash, unlike the Cygwin documentation.

Instance Method Details

#cygwin(cygdrive_prefix = '/cygdrive/') ⇒ Object

Return a Cygwin style path String. See Windirs.Path.initialize documentation for more info on cygdrive_prefix.

> winpath.cygwin
=> "/cygdrive/c/Users/noah/Desktop"

  fpath('/', cygdrive_prefix){|drive| "#{@drive.downcase}"}
end

#nix(prefix = '/') ⇒ Object

Return a *nix (Linux, Mac OS X, *BSD) style path String. prefix will be used if a drive was detected in Path, but this is unlikely to be useful. You may want to assign it for certain Samba situations, but I have little opinion or knowledge on that.

> winpath.nix
=> "/c/Users/noah/Desktop"

#win_deref ⇒ Object
