Reads the file from pathname, then parses it like ::parse, returning the root node of the abstract syntax tree.
SyntaxError is raised if pathname‘s contents are not valid Ruby syntax.
RubyVM::AbstractSyntaxTree.parse_file("my-app/app.rb") # => #<RubyVM::AbstractSyntaxTree::Node(NODE_SCOPE(0) 1:0, 31:3): >
Parses a C prototype signature
If Hash tymap is provided, the return value and the arguments from the signature are expected to be keys, and the value will be the C type to be looked up.
Example:
require 'fiddle/import' include Fiddle::CParser #=> Object parse_signature('double sum(double, double)') #=> ["sum", Fiddle::TYPE_DOUBLE, [Fiddle::TYPE_DOUBLE, Fiddle::TYPE_DOUBLE]] parse_signature('void update(void (*cb)(int code))') #=> ["update", Fiddle::TYPE_VOID, [Fiddle::TYPE_VOIDP]] parse_signature('char (*getbuffer(void))[80]') #=> ["getbuffer", Fiddle::TYPE_VOIDP, []]
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
Mixes the bytes from str into the Pseudo Random Number Generator(PRNG) state.
Thus, if the data from str are unpredictable to an adversary, this increases the uncertainty about the state and makes the PRNG output less predictable.
The entropy argument is (the lower bound of) an estimate of how much randomness is contained in str, measured in bytes.
pid = $$ now = Time.now ary = [now.to_i, now.nsec, 1000, pid] OpenSSL::Random.add(ary.join, 0.0) OpenSSL::Random.seed(ary.join)
Generates a String with length number of cryptographically strong pseudo-random bytes.
OpenSSL::Random.random_bytes(12) #=> "..."
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
Get the raw cookies as a string.

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>
Generates a radio-button Input element.
name is the name of the input field. value is the value of the field if checked. checked specifies whether the field starts off checked.
Alternatively, the attributes can be specified as a hash.
radio_button("name", "value") # <INPUT TYPE="radio" NAME="name" VALUE="value"> radio_button("name", "value", true) # <INPUT TYPE="radio" NAME="name" VALUE="value" CHECKED> radio_button("NAME" => "name", "VALUE" => "value", "ID" => "foo") # <INPUT TYPE="radio" NAME="name" VALUE="value" ID="foo">
Generate a sequence of radio button Input elements, as a String.
This works the same as checkbox_group(). However, it is not valid to have more than one radiobutton in a group checked.
radio_group("name", "foo", "bar", "baz") # <INPUT TYPE="radio" NAME="name" VALUE="foo">foo # <INPUT TYPE="radio" NAME="name" VALUE="bar">bar # <INPUT TYPE="radio" NAME="name" VALUE="baz">baz radio_group("name", ["foo"], ["bar", true], "baz") # <INPUT TYPE="radio" NAME="name" VALUE="foo">foo # <INPUT TYPE="radio" CHECKED NAME="name" VALUE="bar">bar # <INPUT TYPE="radio" NAME="name" VALUE="baz">baz radio_group("name", ["1", "Foo"], ["2", "Bar", true], "Baz") # <INPUT TYPE="radio" NAME="name" VALUE="1">Foo # <INPUT TYPE="radio" CHECKED NAME="name" VALUE="2">Bar # <INPUT TYPE="radio" NAME="name" VALUE="Baz">Baz radio_group("NAME" => "name", "VALUES" => ["foo", "bar", "baz"]) radio_group("NAME" => "name", "VALUES" => [["foo"], ["bar", true], "baz"]) radio_group("NAME" => "name", "VALUES" => [["1", "Foo"], ["2", "Bar", true], "Baz"])
Sets the HTTP Range: header. Accepts either a Range object as a single argument, or a beginning index and a length from that index. Example:
req.range = (0..1023) req.set_range 0, 1023
Returns a Range object which represents the value of the Content-Range: header field. For a partial entity body, this indicates where this fragment fits inside the full entity body, as range of byte offsets.
The length of the range represented in Content-Range: header.

Called when a tag is encountered. @p name the tag name @p attrs an array of arrays of attribute/value pairs, suitable for use with assoc or rassoc. IE, <tag attr1=“value1” attr2=“value2”> will result in tag_start( “tag”, # [[“attr1”,“value1”],])
Displays an error statement to the error output location. Asks a question if given.
