A DSL that provides the means to dynamically load libraries and build modules around them including calling extern functions within the C library that has been loaded.
require 'fiddle' require 'fiddle/import' module LibSum extend Fiddle::Importer dlload './libsum.so' extern 'double sum(double*, int)' extern 'double split(double)' end
Used to construct C classes (CUnion
, CStruct
, etc)
Fiddle::Importer#struct
and Fiddle::Importer#union
wrap this functionality in an easy-to-use manner.
OpenSSL
IO
buffering mix-in module.
This module allows an OpenSSL::SSL::SSLSocket
to behave like an IO
.
You typically won’t use this module directly, you can see it implemented in OpenSSL::SSL::SSLSocket
.
The GC
profiler provides access to information on GC
runs including time, length and object space size.
Example:
GC::Profiler.enable require 'rdoc/rdoc' GC::Profiler.report GC::Profiler.disable
See also GC.count
, GC.malloc_allocated_size
and GC.malloc_allocations
Mixin module that provides the following:
Access to the CGI
environment variables as methods. See documentation to the CGI
class for a list of these variables. The methods are exposed by removing the leading HTTP_
(if it exists) and downcasing the name. For example, auth_type
will return the environment variable AUTH_TYPE
, and accept
will return the value for HTTP_ACCEPT
.
Access to cookies, including the cookies attribute.
Access to parameters, including the params attribute, and overloading []
to perform parameter value lookup by key.
The initialize_query
method, for initializing the above mechanisms, handling multipart forms, and allowing the class to be used in “offline” mode.
The Observable
module extended to DRb
. See Observable
for details.
This module has all methods of FileUtils
module, but it outputs messages before acting. This equates to passing the :verbose
flag to methods in FileUtils
.
The HTTPHeader
module defines methods for reading and writing HTTP
headers.
It is used as a mixin by other classes, to provide hash-like access to HTTP
header values. Unlike raw hash access, HTTPHeader
provides access via case-insensitive keys. It also provides methods for accessing commonly-used HTTP
header values in more convenient formats.
A template for stream parser listeners. Note that the declarations (attlistdecl, elementdecl, etc) are trivially processed; REXML
doesn’t yet handle doctype entity declarations, so you have to parse them out yourself.
ignorable_whitespace
WARNING
These methods are certainly going to change, until DTDs are fully supported. Be aware of this.
