Results for: "module_function"

Divides by the specified value, and returns the quotient and modulus as BigDecimal numbers. The quotient is rounded towards negative infinity.

For example:

require 'bigdecimal'

a = BigDecimal("42")
b = BigDecimal("9")

q, m = a.divmod(b)

c = q * b + m

a == c  #=> true

The quotient q is (a/b).floor, and the modulus is the amount that must be added to q * b to get a.

Sets the stream’s data mode as binary (see Data Mode).

A stream’s data mode may not be changed from binary to text.

Returns true if the stream is on binary mode, false otherwise. See Data Mode.

Changes file permissions.

See File.chmod.

Same as Pathname.chmod, but does not follow symbolic links.

See File.lchmod.

Sets the data mode in self to binary mode; see Data Mode.

Puts ARGF into binary mode. Once a stream is in binary mode, it cannot be reset to non-binary mode. This option has the following effects:

• Newline conversion is disabled.

• Encoding conversion is disabled.

• Content is treated as ASCII-8BIT.

Returns true if ARGF is being read in binary mode; false otherwise. To enable binary mode use ARGF.binmode.

For example:

ARGF.binmode?  #=> false
ARGF.binmode
ARGF.binmode?  #=> true

Returns a BubbleBabble encoded version of a given string.

Changes permissions on the entries at the paths given in list (a single path or an array of paths) to the permissions given by mode; returns list if it is an array, [list] otherwise:

• Modifies each entry that is a regular file using File.chmod.

• Modifies each entry that is a symbolic link using File.lchmod.

Argument list or its elements should be interpretable as paths.

Argument mode may be either an integer or a string:

• Integer mode: represents the permission bits to be set:

  FileUtils.chmod(0755, 'src0.txt')
  FileUtils.chmod(0644, ['src0.txt', 'src0.dat'])
  

• String mode: represents the permissions to be set:

  The string is of the form [targets][[operator][perms[,perms]], where:

  • targets may be any combination of these letters:

    • 'u': permissions apply to the file’s owner.

    • 'g': permissions apply to users in the file’s group.

    • 'o': permissions apply to other users not in the file’s group.

    • 'a' (the default): permissions apply to all users.

  • operator may be one of these letters:

    • '+': adds permissions.

    • '-': removes permissions.

    • '=': sets (replaces) permissions.

  • perms (may be repeated, with separating commas) may be any combination of these letters:

    • 'r': Read.

    • 'w': Write.

    • 'x': Execute (search, for a directory).

    • 'X': Search (for a directories only; must be used with '+')

    • 's': Uid or gid.

    • 't': Sticky bit.

  Examples:

  FileUtils.chmod('u=wrx,go=rx', 'src1.txt')
  FileUtils.chmod('u=wrx,go=rx', '/usr/bin/ruby')
  

Keyword arguments:

• noop: true - does not change permissions; returns nil.

• verbose: true - prints an equivalent command:

  FileUtils.chmod(0755, 'src0.txt', noop: true, verbose: true)
  FileUtils.chmod(0644, ['src0.txt', 'src0.dat'], noop: true, verbose: true)
  FileUtils.chmod('u=wrx,go=rx', 'src1.txt', noop: true, verbose: true)
  FileUtils.chmod('u=wrx,go=rx', '/usr/bin/ruby', noop: true, verbose: true)
  

  Output:

  chmod 755 src0.txt
  chmod 644 src0.txt src0.dat
  chmod u=wrx,go=rx src1.txt
  chmod u=wrx,go=rx /usr/bin/ruby

Called before each event with line/column information.

Sets the continue timeout value, which is the number of seconds to wait for an expected 100 Continue response. If the HTTP object does not receive a response in this many seconds it sends the request body.

Iterates over each option, passing the option to the block.
