Returns the source file origin from the given object.
See ::trace_object_allocations for more information and examples.
Returns the original line from source for from the given object.

Return consuming memory size of obj.
Note that the return size is incomplete. You need to deal with this information as only a HINT. Especially, the size of T_DATA may not be correct.
This method is only expected to work with C Ruby.
From Ruby 2.2, memsize_of(obj) returns a memory size includes sizeof(RVALUE).
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.
Dump a list of objects as separate documents to a document stream.
Example:
Psych.dump_stream("foo\n ", {}) # => "--- ! \"foo\\n \"\n--- {}\n"
Load multiple documents given in yaml. Returns the parsed documents as a list. If a block is given, each document will be converted to Ruby and passed to the block during parsing
Example:
Psych.load_stream("--- foo\n...\n--- bar\n...") # => ['foo', 'bar'] list = [] Psych.load_stream("--- foo\n...\n--- bar\n...") do |ruby| list << ruby end list # => ['foo', 'bar']
This method is deprecated, use Psych.load_stream instead.
Returns the version of libyaml being used
Returns the number of malloc() allocations.
Only available if ruby was built with CALC_EXACT_MALLOC_SIZE.
def_e2message(c, m)
c: exception
m: message_form
define exception c with message m.
Copies stream src to dest. src must respond to read(n) and dest must respond to write(str).

Returns true if the contents of a file A and a file B are identical.
FileUtils.compare_file('somefile', 'somefile') #=> true FileUtils.compare_file('/bin/cp', '/bin/mv') #=> maybe 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('/bin/cp', '/bin/mv') #=> maybe false
Takes a hash as its argument. The key is a symbol or an array of symbols. These symbols correspond to method names. The value is the accessor to which the methods will be delegated.

Tests for the presence of a --with-config or --without-config option. Returns true if the with option is given, false if the without option is given, and the default value otherwise.
This can be useful for adding custom definitions, such as debug information.
Example:
if with_config("debug") $defs.push("-DOSSL_DEBUG") unless $defs.include? "-DOSSL_DEBUG" end
Tests for the presence of an --enable-config or --disable-config option. Returns true if the enable option is given, false if the disable option is given, and the default value otherwise.
This can be useful for adding custom definitions, such as debug information.
Example:
if enable_config("debug") $defs.push("-DOSSL_DEBUG") unless $defs.include? "-DOSSL_DEBUG" end
Generates a header file consisting of the various macro definitions generated by other methods such as have_func and have_header. These are then wrapped in a custom #ifndef based on the header file name, which defaults to “extconf.h”.
For example:
# extconf.rb require 'mkmf' have_func('realpath') have_header('sys/utime.h') create_header create_makefile('foo')
The above script would generate the following extconf.h file:
#ifndef EXTCONF_H #define EXTCONF_H #define HAVE_REALPATH 1 #define HAVE_SYS_UTIME_H 1 #endif
Given that the create_header method generates a file based on definitions set earlier in your extconf.rb file, you will probably want to make this one of the last methods you call in your script.
