Results for: "pstore"

Returns an IO object representing the current file. This will be a File object unless the current file is a stream such as STDIN.

For example:

ARGF.to_io    #=> #<File:glark.txt>
ARGF.to_io    #=> #<IO:<STDIN>>

Reads at most maxlen bytes from the ARGF stream in non-blocking mode.

Returns the value that determines whether headers are to be returned; used for parsing; see {Option return_headers}:

CSV.new('').return_headers? # => false

Returns the value that determines whether all output fields are to be quoted; used for generating; see {Option force_quotes}:

CSV.new('').force_quotes? # => false

Returns a new binding each time near TOPLEVEL_BINDING for runs that do not specify a binding.

Set an error (a protected method).

Return the appropriate error message in POSIX-defined format. If no error has occurred, returns nil.

Creates a new ipaddr containing the given network byte ordered string form of an IP address.

Creates a Range object for the network address.

Set date-time format.

datetime_format

A string suitable for passing to strftime.

Returns the date format being used. See datetime_format=

Returns the usable width for out. As the width of out:

1. If out is assigned to a tty device, its width is used.

2. Otherwise, or it could not get the value, the COLUMN environment variable is assumed to be set to the width.

3. If COLUMN is not set to a non-zero number, 80 is assumed.

And finally, returns the above width value - 1.

• This -1 is for Windows command prompt, which moves the cursor to the next line if it reaches the last column.

Returns a Hash using named capture.

A key of the hash is a name of the named captures. A value of the hash is a string of last successful capture of corresponding group.

m = /(?<a>.)(?<b>.)/.match("01")
m.named_captures #=> {"a" => "0", "b" => "1"}

m = /(?<a>.)(?<b>.)?/.match("0")
m.named_captures #=> {"a" => "0", "b" => nil}

m = /(?<a>.)(?<a>.)/.match("01")
m.named_captures #=> {"a" => "1"}

m = /(?<a>x)|(?<a>y)/.match("x")
m.named_captures #=> {"a" => "x"}

Returns the portion of the original string before the current match. Equivalent to the special variable $`.

m = /(.)(.)(\d+)(\d)/.match("THX1138.")
m.pre_match   #=> "T"

Returns the portion of the original string after the current match. Equivalent to the special variable $'.

m = /(.)(.)(\d+)(\d)/.match("THX1138: The Movie")
m.post_match   #=> ": The Movie"

This is similar to PrettyPrint::format but the result has no breaks.

maxwidth, newline and genspace are ignored.

The invocation of breakable in the block doesn’t break a line and is treated as just an invocation of text.

Returns the group most recently added to the stack.

Contrived example:

out = ""
=> ""
q = PrettyPrint.new(out)
=> #<PrettyPrint:0x82f85c0 @output="", @maxwidth=79, @newline="\n", @genspace=#<Proc:0x82f8368@/home/vbatts/.rvm/rubies/ruby-head/lib/ruby/2.0.0/prettyprint.rb:82 (lambda)>, @output_width=0, @buffer_width=0, @buffer=[], @group_stack=[#<PrettyPrint::Group:0x82f8138 @depth=0, @breakables=[], @break=false>], @group_queue=#<PrettyPrint::GroupQueue:0x82fb7c0 @queue=[[#<PrettyPrint::Group:0x82f8138 @depth=0, @breakables=[], @break=false>]]>, @indent=0>
q.group {
  q.text q.current_group.inspect
  q.text q.newline
  q.group(q.current_group.depth + 1) {
    q.text q.current_group.inspect
    q.text q.newline
    q.group(q.current_group.depth + 1) {
      q.text q.current_group.inspect
      q.text q.newline
      q.group(q.current_group.depth + 1) {
        q.text q.current_group.inspect
        q.text q.newline
      }
    }
  }
}
=> 284
 puts out
#<PrettyPrint::Group:0x8354758 @depth=1, @breakables=[], @break=false>
#<PrettyPrint::Group:0x8354550 @depth=2, @breakables=[], @break=false>
#<PrettyPrint::Group:0x83541cc @depth=3, @breakables=[], @break=false>
#<PrettyPrint::Group:0x8347e54 @depth=4, @breakables=[], @break=false>

This is similar to breakable except the decision to break or not is determined individually.

Two fill_breakable under a group may cause 4 results: (break,break), (break,non-break), (non-break,break), (non-break,non-break). This is different to breakable because two breakable under a group may cause 2 results: (break,break), (non-break,non-break).

The text sep is inserted if a line is not broken at this 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.
