Results for: "fnmatch"

Returns the list of private methods accessible to obj. If the all parameter is set to false, only those methods in the receiver will be listed.

Returns the backtrace (the list of code locations that led to the exception), as an array of Thread::Backtrace::Location instances.

Example (assuming the code is stored in the file named t.rb):

def division(numerator, denominator)
  numerator / denominator
end

begin
  division(1, 0)
rescue => ex
  p ex.backtrace_locations
  # ["t.rb:2:in 'Integer#/'", "t.rb:2:in 'Object#division'", "t.rb:6:in '<main>'"]
  loc = ex.backtrace_locations.first
  p loc.class
  # Thread::Backtrace::Location
  p loc.path
  # "t.rb"
  p loc.lineno
  # 2
  p loc.label
  # "Integer#/"
end

The value returned by this method might be adjusted when raising (see Kernel#raise), or during intermediate handling by set_backtrace.

See also backtrace that provide the same value as an array of strings. (Note though that two values might not be consistent with each other when backtraces are manually adjusted.)

See Backtraces.

See as_json.

Return true if the caused method was called as private.

When this module is included in another, Ruby calls append_features in this module, passing it the receiving module in mod. Ruby’s default implementation is to add the constants, methods, and module variables of this module to mod if this module has not already been added to mod or one of its ancestors. See also Module#include.

When this module is prepended in another, Ruby calls prepend_features in this module, passing it the receiving module in mod. Ruby’s default implementation is to overlay the constants, methods, and module variables of this module to mod if this module has not already been added to mod or one of its ancestors. See also Module#prepend.

Creates instance variables and corresponding methods that return the value of each instance variable. Equivalent to calling “attr:name” on each name in turn. String arguments are converted to symbols. Returns an array of defined method names as symbols.

Creates an accessor method to allow assignment to the attribute symbol.id2name. String arguments are converted to symbols. Returns an array of defined method names as symbols.

Defines a named attribute for this module, where the name is symbol.id2name, creating an instance variable (@name) and a corresponding access method to read it. Also creates a method called name= to set the attribute. String arguments are converted to symbols. Returns an array of defined method names as symbols.

module Mod
  attr_accessor(:one, :two) #=> [:one, :one=, :two, :two=]
end
Mod.instance_methods.sort   #=> [:one, :one=, :two, :two=]

Makes a list of existing constants private.

Makes a list of existing constants deprecated. Attempt to refer to them will produce a warning.

module HTTP
  NotFound = Exception.new
  NOT_FOUND = NotFound # previous version of the library used this name

  deprecate_constant :NOT_FOUND
end

HTTP::NOT_FOUND
# warning: constant HTTP::NOT_FOUND is deprecated

Return the accept character set for all new CGI instances.

Set the accept character set for all new CGI instances.

Returns true if the arguments define a valid ordinal date, false otherwise:

Date.valid_date?(2001, 2, 3)  # => true
Date.valid_date?(2001, 2, 29) # => false
Date.valid_date?(2001, 2, -1) # => true

See argument start.

Returns self.

Returns a DateTime whose value is the same as self:

Date.new(2001, 2, 3).to_datetime # => #<DateTime: 2001-02-03T00:00:00+00:00>

See as_json.

Returns a Date object which denotes self.

Returns self.

See as_json.

Returns a Date object which denotes self.

Returns a DateTime object which denotes self.

See as_json.

Returns the offset in seconds between the timezones of UTC and self:

Time.utc(2000, 1, 1).utc_offset   # => 0
Time.local(2000, 1, 1).utc_offset # => -21600 # -6*3600, or minus six hours.

Calls the block with each remaining line read from the stream; returns self. Does nothing if already at end-of-stream; See Line IO.

With no arguments given, reads lines as determined by line separator $/:

f = File.new('t.txt')
f.each_line {|line| p line }
f.each_line {|line| fail 'Cannot happen' }
f.close

Output:

"First line\n"
"Second line\n"
"\n"
"Fourth line\n"
"Fifth line\n"

With only string argument sep given, reads lines as determined by line separator sep; see Line Separator:

f = File.new('t.txt')
f.each_line('li') {|line| p line }
f.close

Output:

"First li"
"ne\nSecond li"
"ne\n\nFourth li"
"ne\nFifth li"
"ne\n"

The two special values for sep are honored:

f = File.new('t.txt')
# Get all into one string.
f.each_line(nil) {|line| p line }
f.close

Output:

"First line\nSecond line\n\nFourth line\nFifth line\n"

f.rewind
# Get paragraphs (up to two line separators).
f.each_line('') {|line| p line }

Output:

"First line\nSecond line\n\n"
"Fourth line\nFifth line\n"

With only integer argument limit given, limits the number of bytes in each line; see Line Limit:

f = File.new('t.txt')
f.each_line(8) {|line| p line }
f.close

Output:

"First li"
"ne\n"
"Second l"
"ine\n"
"\n"
"Fourth l"
"ine\n"
"Fifth li"
"ne\n"

With arguments sep and limit given, combines the two behaviors (see Line Separator and Line Limit).

Optional keyword argument chomp specifies whether line separators are to be omitted:

f = File.new('t.txt')
f.each_line(chomp: true) {|line| p line }
f.close

Output:

"First line"
"Second line"
""
"Fourth line"
"Fifth line"

Returns an Enumerator if no block is given.
