Alias for CSV.read.

Rewinds the underlying IO object and resets CSV’s lineno() counter.

Forms the remaining rows from self into:

• A CSV::Table object, if headers are in use.

• An Array of Arrays, otherwise.

The data source must be opened for reading.

Without headers:

string = "foo,0\nbar,1\nbaz,2\n"
path = 't.csv'
File.write(path, string)
csv = CSV.open(path)
csv.read # => [["foo", "0"], ["bar", "1"], ["baz", "2"]]

With headers:

string = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
path = 't.csv'
File.write(path, string)
csv = CSV.open(path, headers: true)
csv.read # => #<CSV::Table mode:col_or_row row_count:4>

Raises an exception if the source is not opened for reading:

string = "foo,0\nbar,1\nbaz,2\n"
csv = CSV.new(string)
csv.close
# Raises IOError (not opened for reading)
csv.read

:method: freeze Freeze both the object returned by _getobj_ and self.

Executes the generated ERB code to produce a completed template, returning the results of that code. (See ERB::new for details on how this process can be affected by safe_level.)

b accepts a Binding object which is used to set the context of code evaluation.

Returns a new ipaddr built by converting the IPv6 address into a native IPv4 address. If the IP address is not an IPv4-mapped or IPv4-compatible IPv6 address, returns self.

Returns the prefix length in bits for the ipaddr.

Sets the prefix length in bits

Set logging severity threshold.

severity

The Severity of the log message.

Args

logdev

The log device. This is a filename (String) or IO object (typically STDOUT, STDERR, or an open file). reopen the same filename if it is nil, do nothing for IO. Default is nil.

Description

Reopen a log device.

Directs to reject specified class argument.

t

Argument class specifier, any object including Class.

reject(t)

See reject.

Release code

Returns version string from program_name, version and release.

Returns the regexp.

m = /a.*b/.match("abc")
m.regexp #=> /a.*b/

Returns the array of captures; equivalent to mtch.to_a[1..-1].

f1,f2,f3,f4 = /(.)(.)(\d+)(\d)/.match("THX1138.").captures
f1    #=> "H"
f2    #=> "X"
f3    #=> "113"
f4    #=> "8"

This says “you can break a line here if necessary”, and a width-column text sep is inserted if a line is not broken at the point.

If sep is not specified, “ ” is used.

If width is not specified, sep.length is used. You will have to specify this when sep is a multibyte character, for example.

Looks up the first IP address for name.

Looks up all IP address for name.

Looks up the first IP address for name.

Looks up all IP address for name.

Creates a temporary file as a usual File object (not a Tempfile). It does not use finalizer and delegation, which makes it more efficient and reliable.

If no block is given, this is similar to Tempfile.new except creating File instead of Tempfile. In that case, the created file is not removed automatically. You should use File.unlink to remove it.

If a block is given, then a File object will be constructed, and the block is invoked with the object as the argument. The File object will be automatically closed and the temporary file is removed after the block terminates, releasing all resources that the block created. The call returns the value of the block.

In any case, all arguments (basename, tmpdir, mode, and **options) will be treated the same as for Tempfile.new.

Tempfile.create('foo', '/home/temp') do |f|
   # ... do something with f ...
end
