Adds aProc as a finalizer, to be called after obj was destroyed. The object ID of the obj will be passed as an argument to aProc. If aProc is a lambda or method, make sure it can be called with a single argument.
Removes all finalizers for obj.
Parse a file at filename. Returns the Psych::Nodes::Document.
Raises a Psych::SyntaxError when a YAML syntax error is detected.
Parse a YAML string in yaml. Returns the Psych::Nodes::Stream. This method can handle multiple YAML documents contained in yaml. filename is used in the exception message if a Psych::SyntaxError is raised.
If a block is given, a Psych::Nodes::Document node will be yielded to the block as it’s being parsed.
Raises a Psych::SyntaxError when a YAML syntax error is detected.
Example:
Psych.parse_stream("---\n - a\n - b") # => #<Psych::Nodes::Stream:0x00> Psych.parse_stream("--- a\n--- b") do |node| node # => #<Psych::Nodes::Document:0x00> end begin Psych.parse_stream("--- `", filename: "file.txt") rescue Psych::SyntaxError => ex ex.file # => 'file.txt' ex.message # => "(file.txt): found character that cannot start any token" end
Raises a TypeError when NilClass is passed.
See Psych::Nodes for more information about YAML AST.
Returns the full line that is being edited. This is useful from within the complete_proc for determining the context of the completion request.
The length of Readline.line_buffer and GNU Readline’s rl_end are same.
Raises NotImplementedError if the using readline library does not support.
Clear the current input line.
Combine two Adler-32 check values in to one. alder1 is the first Adler-32 value, adler2 is the second Adler-32 value. len2 is the length of the string used to generate adler2.
Combine two CRC-32 check values in to one. crc1 is the first CRC-32 value, crc2 is the second CRC-32 value. len2 is the length of the string used to generate crc2.
The mode needed to read a file as straight binary.
Reset the dir and path values. The next time dir or path is requested, the values will be calculated from scratch. This is mainly used by the unit tests to provide test isolation.
The version of the Marshal format for your Ruby.
Adds a post-installs hook that will be passed a Gem::DependencyInstaller and a list of installed specifications when Gem::DependencyInstaller#install is complete
Safely read a file in binary mode on all platforms.
Safely write a file in binary mode on all platforms.
Start a dRuby server locally.
The new dRuby server will become the primary server, even if another server is currently the primary server.
uri is the URI for the server to bind to. If nil, the server will bind to random port on the default local host name and use the default dRuby protocol.
front is the server’s front object. This may be nil.
config is the configuration for the new server. This may be nil.
See DRbServer::new.

Get the ‘current’ server.
In the context of execution taking place within the main thread of a dRuby server (typically, as a result of a remote call on the server or one of its objects), the current server is that server. Otherwise, the current server is the primary server.
If the above rule fails to find a server, a DRbServerNotFound error is raised.

Returns true if the contents of a file a and a file b are identical.
FileUtils.compare_file('somefile', 'somefile') #=> true FileUtils.compare_file('/dev/null', '/dev/urandom') #=> false
Returns true if the contents of a file a and a file b are identical.
FileUtils.compare_file('somefile', 'somefile') #=> true FileUtils.compare_file('/dev/null', '/dev/urandom') #=> false
Returns true if the contents of a stream a and b are identical.
