instance method

Pathname#/

(::Pathname | ::String | ::_ToStr other) -> ::Pathname

/(other)

# File tmp/rubies/ruby-4.1.0-preview1/pathname_builtin.rb, line 909
def +(other)
  other = Pathname.new(other) unless Pathname === other
  Pathname.new(plus(@path, other.path))
end

Alias of #+

Returns a new Pathname object based on the content of self and other; argument other may be a String, a File, a Dir, or another Pathname:

Example

pn = Pathname('foo')     # => #<Pathname:foo>
pn + 'bar'               # => #<Pathname:foo/bar>
pn + File.new('LEGAL')   # => #<Pathname:foo/LEGAL>
pn + Dir.new('lib')      # => #<Pathname:foo/lib>
pn + Pathname('bar')     # => #<Pathname:foo/bar>

When other specifies a relative path (see relative?), it is combined with self to form a new pathname:

Example

Pathname('/a/b') + 'c' # => #<Pathname:/a/b/c>

Extra component separators ('/') are removed:

Example

Pathname('/a/b/') + 'c' # => #<Pathname:/a/b/c>

Extra current-directory components ('.') are removed:

Example

Pathname('a') + '.' # => #<Pathname:a>
Pathname('.') + 'a' # => #<Pathname:a>
Pathname('.') + '.' # => #<Pathname:.>

Parent-directory components ('..') are:

Resolved, when possible:

Example

Pathname('a')      + '..'      # => #<Pathname:.>
Pathname('a/b')    + '..'      # => #<Pathname:a>
Pathname('/')      + '../a'    # => #<Pathname:/a>
Pathname('a')      + '../b'    # => #<Pathname:b>
Pathname('a/b')    + '../c'    # => #<Pathname:a/c>
Pathname('a//b/c') + '../d//e' # => #<Pathname:a//b/d//e>

Removed, when not needed:

Example
```
Pathname('/') + '..' # => #<Pathname:/>
```

Retained, when needed:

Example

Pathname('..') + '..'   # => #<Pathname:../..>
Pathname('..') + '../a' # => #<Pathname:../../a>

When other specifies an absolute path (see absolute?), equivalent to Pathname(other.to_s):

Example

Pathname('/a') + '/b/c' # => #<Pathname:/b/c>

Occurrences of '/', '.', and '..' are preserved:

Example

Pathname('/a') + '//b//c/./../d' # => #<Pathname://b//c/./../d>

This method does not access the file system, so other need not represent an existing (or even a valid) file or directory path:

Example

Pathname('/var') + 'nosuch:ever' # => #<Pathname:/var/nosuch:ever>
