This method provides the metavariables defined by the revision 3 of “The WWW Common Gateway Interface Version 1.1” To browse the current document of CGI Version 1.1, see below: tools.ietf.org/html/rfc3875
The response’s HTTP status line
The content-length header
Sets the content-length header to len
Returns an array containing the values associated with the given keys.
Calls the given block once for each key, value pair in the database.
Returns self.
Returns the length of the hash value of the digest.
This method should be overridden by each implementation subclass. If not, digest_obj.digest().length() is returned.
Returns the block length of the digest.
This method is overridden by each implementation subclass.
Given a String of C type ty, returns the corresponding Fiddle constant.
ty can also accept an Array of C type Strings, and will be returned in a corresponding Array.
If Hash tymap is provided, ty is expected to be the key, and the value will be the C type to be looked up.
Example:
require 'fiddle/import' include Fiddle::CParser #=> Object parse_ctype('int') #=> Fiddle::TYPE_INT parse_ctype('double diff') #=> Fiddle::TYPE_DOUBLE parse_ctype('unsigned char byte') #=> -Fiddle::TYPE_CHAR parse_ctype('const char* const argv[]') #=> -Fiddle::TYPE_VOIDP
Creates a class to wrap the C struct with the value ty

Consumes size bytes from the buffer
Returns an Array of individual raw profile data Hashes ordered from earliest to latest by :GC_INVOKE_TIME.
For example:
[
{
:GC_TIME=>1.3000000000000858e-05,
:GC_INVOKE_TIME=>0.010634999999999999,
:HEAP_USE_SIZE=>289640,
:HEAP_TOTAL_SIZE=>588960,
:HEAP_TOTAL_OBJECTS=>14724,
:GC_IS_MARKED=>false
},
# ...
]
The keys mean:
:GC_TIME
:GC_INVOKE_TIME
Time elapsed in seconds from startup to when the GC was invoked
:HEAP_USE_SIZE
Total bytes of heap used
:HEAP_TOTAL_SIZE
Total size of heap in bytes
:HEAP_TOTAL_OBJECTS
Total number of objects
:GC_IS_MARKED
Returns true if the GC is in mark phase
If ruby was built with GC_PROFILE_MORE_DETAIL, you will also have access to the following hash keys:
:GC_MARK_TIME
:GC_SWEEP_TIME
:ALLOCATE_INCREASE
:ALLOCATE_LIMIT
:HEAP_USE_PAGES
:HEAP_LIVE_OBJECTS
:HEAP_FREE_OBJECTS
:HAVE_FINALIZE
The total time used for garbage collection in seconds

Parses multipart form elements according to
http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.2
Returns a hash of multipart form parameters with bodies of type StringIO or Tempfile depending on whether the multipart form element exceeds 10 KB
params[name => body]
Generate a Form element with multipart encoding as a String.
Multipart encoding is used for forms that include file uploads.
action is the action to perform. enctype is the encoding type, which defaults to “multipart/form-data”.
Alternatively, the attributes can be specified as a hash.
multipart_form{ "string" } # <FORM METHOD="post" ENCTYPE="multipart/form-data">string</FORM> multipart_form("url") { "string" } # <FORM METHOD="post" ACTION="url" ENCTYPE="multipart/form-data">string</FORM>
Generate a Password Input element as a string.
name is the name of the input field. value is its default value. size is the size of the input field display. maxlength is the maximum length of the inputted password.
Alternatively, attributes can be specified as a hash.
password_field("name") # <INPUT TYPE="password" NAME="name" SIZE="40"> password_field("name", "value") # <INPUT TYPE="password" NAME="name" VALUE="value" SIZE="40"> password_field("password", "value", 80, 200) # <INPUT TYPE="password" NAME="name" VALUE="value" SIZE="80" MAXLENGTH="200"> password_field("NAME" => "name", "VALUE" => "value") # <INPUT TYPE="password" NAME="name" VALUE="value">
Generate a Select element as a string.
name is the name of the element. The values are the options that can be selected from the Select menu. Each value can be a String or a one, two, or three-element Array. If a String or a one-element Array, this is both the value of that option and the text displayed for it. If a three-element Array, the elements are the option value, displayed text, and a boolean value specifying whether this option starts as selected. The two-element version omits either the option value (defaults to the same as the display text) or the boolean selected specifier (defaults to false).
The attributes and options can also be specified as a hash. In this case, options are specified as an array of values as described above, with the hash key of “VALUES”.
popup_menu("name", "foo", "bar", "baz") # <SELECT NAME="name"> # <OPTION VALUE="foo">foo</OPTION> # <OPTION VALUE="bar">bar</OPTION> # <OPTION VALUE="baz">baz</OPTION> # </SELECT> popup_menu("name", ["foo"], ["bar", true], "baz") # <SELECT NAME="name"> # <OPTION VALUE="foo">foo</OPTION> # <OPTION VALUE="bar" SELECTED>bar</OPTION> # <OPTION VALUE="baz">baz</OPTION> # </SELECT> popup_menu("name", ["1", "Foo"], ["2", "Bar", true], "Baz") # <SELECT NAME="name"> # <OPTION VALUE="1">Foo</OPTION> # <OPTION SELECTED VALUE="2">Bar</OPTION> # <OPTION VALUE="Baz">Baz</OPTION> # </SELECT> popup_menu("NAME" => "name", "SIZE" => 2, "MULTIPLE" => true, "VALUES" => [["1", "Foo"], ["2", "Bar", true], "Baz"]) # <SELECT NAME="name" MULTIPLE SIZE="2"> # <OPTION VALUE="1">Foo</OPTION> # <OPTION SELECTED VALUE="2">Bar</OPTION> # <OPTION VALUE="Baz">Baz</OPTION> # </SELECT>
Returns an Integer object which represents the HTTP Content-Length: header field, or nil if that field was not provided.
