- !ruby/struct:SM::Flow::H
level: 2
text: Pathname
- !ruby/struct:SM::Flow::P
body: "Pathname represents a pathname which locates a file in a filesystem. The pathname depends on OS: Unix, Windows, etc. Pathname library works with pathnames of local OS. However non-Unix pathnames are supported experimentally."
- !ruby/struct:SM::Flow::P
body: It does not represent the file itself. A Pathname can be relative or absolute. It's not until you try to reference the file that it even matters whether the file exists or not.
- !ruby/struct:SM::Flow::P
body: Pathname is immutable. It has no method for destructive update.
- !ruby/struct:SM::Flow::P
body: The value of this class is to manipulate file path information in a neater way than standard Ruby provides. The examples below demonstrate the difference. <b>All</b> functionality from File, FileTest, and some from Dir and FileUtils is included, in an unsurprising way. It is essentially a facade for all of these, and more.

text: Method documentation
- !ruby/struct:SM::Flow::P
body: As the above section shows, most of the methods in Pathname are facades. The documentation for these methods generally just says, for instance, "See FileTest.writable?", as you should be familiar with the original method anyway, and its documentation (e.g. through <tt>ri</tt>) will contain more information. In some cases, a brief description will follow.
