Specifies a File object input that is input stream for Readline.readline method.
Returns the index of the current cursor position in Readline.line_buffer.
The index in Readline.line_buffer which matches the start of input-string passed to completion_proc is computed by subtracting the length of input-string from Readline.point.
start = (the length of input-string) - Readline.point
Raises NotImplementedError if the using readline library does not support.
Set the index of the current cursor position in Readline.line_buffer.
Raises NotImplementedError if the using readline library does not support.
See Readline.point.
Returns the log priority mask in effect. The mask is not reset by opening or closing syslog.
Sets the log priority mask. A method LOG_UPTO is defined to make it easier to set mask values. Example:
Syslog.mask = Syslog::LOG_UPTO(Syslog::LOG_ERR)
Alternatively, specific priorities can be selected and added together using binary OR. Example:
Syslog.mask = Syslog::LOG_MASK(Syslog::LOG_ERR) | Syslog::LOG_MASK(Syslog::LOG_CRIT)
The priority mask persists through calls to open() and close().
Returns an inspect() string summarizing the object state.
Returns self, for backward compatibility.
Decompresses string. Raises a Zlib::NeedDict exception if a preset dictionary is needed for decompression.
This method is almost equivalent to the following code:
def inflate(string) zstream = Zlib::Inflate.new buf = zstream.inflate(string) zstream.finish zstream.close buf end
See also Zlib.deflate
Returns true if the named file is a symbolic link.
Invokes the block with a Benchmark::Report object, which may be used to collect and report on the results of individual benchmark tests. Reserves label_width leading spaces for labels on each line. Prints caption at the top of the report, and uses format to format each line. Returns an array of Benchmark::Tms objects.
If the block returns an array of Benchmark::Tms objects, these will be used to format additional lines of output. If labels parameter are given, these are used to label these extra lines.
Note: Other methods provide a simpler interface to this one, and are suitable for nearly all benchmarking requirements. See the examples in Benchmark, and the bm and bmbm methods.
Example:
require 'benchmark' include Benchmark # we need the CAPTION and FORMAT constants n = 5000000 Benchmark.benchmark(CAPTION, 7, FORMAT, ">total:", ">avg:") do |x| tf = x.report("for:") { for i in 1..n; a = "1"; end } tt = x.report("times:") { n.times do ; a = "1"; end } tu = x.report("upto:") { 1.upto(n) do ; a = "1"; end } [tf+tt+tu, (tf+tt+tu)/3] end
