Construct a new class given a C:
class klass (CUnion, CStruct, or other that provide an entity_class)
types (Fiddle::TYPE_INT, Fiddle::TYPE_SIZE_T, etc., see the C types constants)
corresponding members
Fiddle::Importer#struct and Fiddle::Importer#union wrap this functionality in an easy-to-use manner.
Example:
require 'fiddle/struct' require 'fiddle/cparser' include Fiddle::CParser types, members = parse_struct_signature(['int i','char c']) MyStruct = Fiddle::CStructBuilder.create(Fiddle::CUnion, types, members) obj = MyStruct.allocate

Similar to read, but raises EOFError at end of string instead of returning nil, as well as IO#sysread does.

Reads size bytes from the stream. If buf is provided it must reference a string which will receive the data.
See IO#read for full details.
Reads at most maxlen bytes from the stream. If buf is provided it must reference a string which will receive the data.
See IO#readpartial for full details.
Reads a line from the stream which is separated by eol.
Raises EOFError if at end of file.
Reads a one-character string from the stream. Raises an EOFError at end of file.
Reads a DER or PEM encoded string from string or io and returns an instance of the appropriate PKey class.
string is a DER- or PEM-encoded string containing an arbitrary private or public key.
io is an instance of IO containing a DER- or PEM-encoded arbitrary private or public key.
pwd is an optional password in case string or file is an encrypted PEM resource.
Return true if the PRNG has been seeded with enough data, false otherwise.

Returns a profile data report such as:

Prettify (indent) an HTML string.
string is the HTML string to indent. shift is the indentation unit to use; it defaults to two spaces.
print CGI::pretty("<HTML><BODY></BODY></HTML>") # <HTML> # <BODY> # </BODY> # </HTML> print CGI::pretty("<HTML><BODY></BODY></HTML>", "\t") # <HTML> # <BODY> # </BODY> # </HTML>
Generate a Form element as a string.
method should be either “get” or “post”, and defaults to the latter. action defaults to the current CGI script name. enctype defaults to “application/x-www-form-urlencoded”.
Alternatively, the attributes can be specified as a hash.
See also multipart_form() for forms that include file uploads.
form{ "string" } # <FORM METHOD="post" ENCTYPE="application/x-www-form-urlencoded">string</FORM> form("get") { "string" } # <FORM METHOD="get" ENCTYPE="application/x-www-form-urlencoded">string</FORM> form("get", "url") { "string" } # <FORM METHOD="get" ACTION="url" ENCTYPE="application/x-www-form-urlencoded">string</FORM> form("METHOD" => "post", "ENCTYPE" => "enctype") { "string" } # <FORM METHOD="post" ENCTYPE="enctype">string</FORM>
Generate a reset button Input element, as a String.
This resets the values on a form to their initial values. value is the text displayed on the button. name is the name of this button.
Alternatively, the attributes can be specified as a hash.
reset # <INPUT TYPE="reset"> reset("reset") # <INPUT TYPE="reset" VALUE="reset"> reset("VALUE" => "reset", "ID" => "foo") # <INPUT TYPE="reset" VALUE="reset" ID="foo">
Generate a TextArea element, as a String.
name is the name of the textarea. cols is the number of columns and rows is the number of rows in the display.
Alternatively, the attributes can be specified as a hash.
The body is provided by the passed-in no-argument block
textarea("name") # = textarea("NAME" => "name", "COLS" => 70, "ROWS" => 10) textarea("name", 40, 5) # = textarea("NAME" => "name", "COLS" => 40, "ROWS" => 5)
OpenURI::OpenRead#read([options]) reads a content referenced by self and returns the content as string. The string is extended with OpenURI::Meta. The argument options is same as OpenURI::OpenRead#open.
Parses self destructively in order and returns self containing the rest arguments left unparsed.
Substitution of getopts is possible as follows. Also see OptionParser#getopts.
def getopts(*args) ($OPT = ARGV.getopts(*args)).each do |opt, val| eval "$OPT_#{opt.gsub(/[^A-Za-z0-9_]/, '_')} = val" end rescue OptionParser::ParseError end
Adds a separated list. The list is separated by comma with breakable space, by default.
seplist iterates the list using iter_method. It yields each object to the block given for seplist. The procedure separator_proc is called between each yields.
If the iteration is zero times, separator_proc is not called at all.
If separator_proc is nil or not given, +lambda { comma_breakable }+ is used. If iter_method is not given, :each is used.
For example, following 3 code fragments has similar effect.
q.seplist([1,2,3]) {|v| xxx v } q.seplist([1,2,3], lambda { q.comma_breakable }, :each) {|v| xxx v } xxx 1 q.comma_breakable xxx 2 q.comma_breakable xxx 3
