Sets optional filename and line number that will be used in ERB code evaluation and error reporting. See also filename= and lineno=
erb = ERB.new('<%= some_x %>') erb.render # undefined local variable or method `some_x' # from (erb):1 erb.location = ['file.erb', 3] # All subsequent error reporting would use new location erb.render # undefined local variable or method `some_x' # from file.erb:4
Terminate option processing; returns nil if processing has already terminated; otherwise returns self.
Returns true if option processing has terminated, false otherwise.
Calls the given block with each option; each option is a 2-element array containing:
The option name (the name itself, not an alias).
The option value.
Example:
require 'getoptlong' options = GetoptLong.new( ['--xxx', '-x', GetoptLong::REQUIRED_ARGUMENT], ['--yyy', '-y', GetoptLong::OPTIONAL_ARGUMENT], ['--zzz', '-z',GetoptLong::NO_ARGUMENT] ) puts "Original ARGV: #{ARGV}" options.each do |option, argument| p [option, argument] end puts "Remaining ARGV: #{ARGV}"
Command line:
ruby each.rb -xxx Foo -x Bar --yyy Baz -y Bat --zzz
Output:
Original ARGV: ["-xxx", "Foo", "-x", "Bar", "--yyy", "Baz", "-y", "Bat", "--zzz"] ["--xxx", "xx"] ["--xxx", "Bar"] ["--yyy", "Baz"] ["--yyy", "Bat"] ["--zzz", ""] Remaining ARGV: ["Foo"]
Returns a new ipaddr built by masking IP address with the given prefixlen/netmask. (e.g. 8, 64, “255.255.255.0”, etc.)
Returns true if the ipaddr is a private address. IPv4 addresses in 10.0.0.0/8, 172.16.0.0/12 and 192.168.0.0/16 as defined in RFC 1918 and IPv6 Unique Local Addresses in fc00::/7 as defined in RFC 4193 are considered private. Private IPv4 addresses in the IPv4-mapped IPv6 address range are also considered private.
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.
Returns the netmask in string format e.g. 255.255.0.0
Set current netmask to given mask.
Returns true if the log level allows entries with severity Logger::FATAL to be written, false otherwise. See Log Level.
Sets the log level to Logger::FATAL. See Log Level.
Equivalent to calling add with severity Logger::FATAL.
Terminates option parsing. Optional parameter arg is a string pushed back to be the first non-option argument.
Puts option summary into to and returns to. Yields each line if a block is given.
to
Output destination, which must have method <<. Defaults to [].
width
Width of left side, defaults to @summary_width.
max
Maximum length allowed for left side, defaults to width - 1.
indent
Indentation, defaults to @summary_indent.
Add separator in summary.
Parses environment variable env or its uppercase with splitting like a shell.
env defaults to the basename of the program.
Returns the full path name of the temporary file. This will be nil if unlink has been called.
Creates a file in the underlying file system; returns a new File object based on that file.
With no block given and no arguments, creates and returns file whose:
Directory is the system temporary directory (system-dependent).
Generated filename is unique in that directory.
Permissions are 0600; see File Permissions.
Mode is 'w+' (read/write mode, positioned at the end).
With no block, the file is not removed automatically, and so should be explicitly removed.
Example:
f = Tempfile.create # => #<File:/tmp/20220505-9795-17ky6f6> f.class # => File f.path # => "/tmp/20220505-9795-17ky6f6" f.stat.mode.to_s(8) # => "100600" File.exist?(f.path) # => true File.unlink(f.path) File.exist?(f.path) # => false
Argument basename, if given, may be one of:
A string: the generated filename begins with basename:
Tempfile.create('foo') # => #<File:/tmp/foo20220505-9795-1gok8l9>
An array of two strings [prefix, suffix]: the generated filename begins with prefix and ends with suffix:
Tempfile.create(%w/foo .jpg/) # => #<File:/tmp/foo20220505-17839-tnjchh.jpg>
With arguments basename and tmpdir, the file is created in directory tmpdir:
Tempfile.create('foo', '.') # => #<File:./foo20220505-9795-1emu6g8>
Keyword arguments mode and options are passed directly to method File.open:
The value given with mode must be an integer, and may be expressed as the logical OR of constants defined in File::Constants.
For options, see Open Options.
With a block given, creates the file as above, passes it to the block, and returns the block’s value; before the return, the file object is closed and the underlying file is removed:
Tempfile.create {|file| file.path } # => "/tmp/20220505-9795-rkists"

returns main ractor
Returns the main thread.
Terminates thr and schedules another thread to be run, returning the terminated Thread. If this is the main thread, or the last thread, exits the process.
Returns the status of thr.
"sleep"
Returned if this thread is sleeping or waiting on I/O
"run"
When this thread is executing
"aborting"
If this thread is aborting
false
When this thread is terminated normally
nil
If terminated with an exception.
