Start tracing
Tracer.on # code to trace here Tracer.off
You can also pass a block:
Tracer.on { # trace everything in this block }
Returns the list of waiting threads.
When stepping through the traces of a function, thread gets suspended, to be resumed later.
This method must be overridden by subclasses and change the object delegate to obj.
Changes the delegate object to obj.
It’s important to note that this does not cause SimpleDelegator’s methods to change. Because of this, you probably only want to change delegation to objects of the same type as the original delegate.
Here’s an example of changing the delegation object.
names = SimpleDelegator.new(%w{James Edward Gray II}) puts names[1] # => Edward names.__setobj__(%w{Gavin Sinclair}) puts names[1] # => Sinclair
Set the handling of the ordering of options and arguments. A RuntimeError is raised if option processing has already started.
The supplied value must be a member of GetoptLong::ORDERINGS. It alters the processing of options as follows:
REQUIRE_ORDER :
Options are required to occur before non-options.
Processing of options ends as soon as a word is encountered that has not been preceded by an appropriate option flag.
For example, if -a and -b are options which do not take arguments, parsing command line arguments of ‘-a one -b two’ would result in ‘one’, ‘-b’, ‘two’ being left in ARGV, and only (‘-a’, ”) being processed as an option/arg pair.
This is the default ordering, if the environment variable POSIXLY_CORRECT is set. (This is for compatibility with GNU getopt_long.)
PERMUTE :
Options can occur anywhere in the command line parsed. This is the default behavior.
Every sequence of words which can be interpreted as an option (with or without argument) is treated as an option; non-option words are skipped.
For example, if -a does not require an argument and -b optionally takes an argument, parsing ‘-a one -b two three’ would result in (‘-a’,”) and (‘-b’, ‘two’) being processed as option/arg pairs, and ‘one’,‘three’ being left in ARGV.
If the ordering is set to PERMUTE but the environment variable POSIXLY_CORRECT is set, REQUIRE_ORDER is used instead. This is for compatibility with GNU getopt_long.
RETURN_IN_ORDER :
All words on the command line are processed as options. Words not preceded by a short or long option flag are passed as arguments with an option of ” (empty string).
For example, if -a requires an argument but -b does not, a command line of ‘-a one -b two three’ would result in option/arg pairs of (‘-a’, ‘one’) (‘-b’, ”), (”, ‘two’), (”, ‘three’) being processed.
Explicitly terminate option processing.
Returns true if option processing has terminated, false otherwise.
Convert a network byte ordered string form of an IP address into human readable form.
Returns a network byte ordered string form of the IP address.
Returns true if the ipaddr is a loopback address.
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.
Set +@addr+, the internal stored ip address, to given addr. The parameter addr is validated using the first family member, which is Socket::AF_INET or Socket::AF_INET6.
Returns the bound receiver of the binding object.
Returns true iff the current severity level allows for the printing of WARN messages.
Sets the severity to WARN.
Returns true iff the current severity level allows for the printing of ERROR messages.
Sets the severity to ERROR.
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.
Reopen a log device.
Close the logging device.
