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.

Examples:

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)

MyStruct.malloc(Fiddle::RUBY_FREE) do |obj|
  ...
end

obj = MyStruct.malloc(Fiddle::RUBY_FREE)
begin
  ...
ensure
  obj.call_free
end

obj = MyStruct.malloc
begin
  ...
ensure
  Fiddle.free obj.to_ptr
end

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.

Return true if the PRNG has been seeded with enough data, false otherwise.

Returns whether the form contained multipart/form-data

Parses self destructively and returns self containing the rest arguments left unparsed.

Create a new Location object.

Generate a random alphanumeric string.

The argument n specifies the length, in characters, of the alphanumeric string to be generated. The argument chars specifies the character list which the result is consist of.

If n is not specified or is nil, 16 is assumed. It may be larger in the future.

The result may contain A-Z, a-z and 0-9, unless chars is specified.

require 'random/formatter'

Random.alphanumeric     #=> "2BuBuLf3WfSKyQbR"
# or
prng = Random.new
prng.alphanumeric(10) #=> "i6K93NdqiH"

Random.alphanumeric(4, chars: [*"0".."9"]) #=> "2952"
# or
prng = Random.new
prng.alphanumeric(10, chars: [*"!".."/"]) #=> ",.,++%/''."

Return true if RJIT is enabled.

Start JIT compilation after --rjit-disable.

Simple deprecation method that deprecates name by wrapping it up in a dummy method. It warns on each call to the dummy method telling the user of repl (unless repl is :none) and the year/month that it is planned to go away.

Is fetching of local and remote information enabled?

A Zlib::Inflate#inflate wrapper

Check if YJIT is enabled.

Enable YJIT compilation. stats option decides whether to enable YJIT stats or not. compilation_log decides whether to enable YJIT compilation logging or not.

• stats:

  • false: Don’t enable stats.

  • true: Enable stats. Print stats at exit.

  • :quiet: Enable stats. Do not print stats at exit.

• log:

  • false: Don’t enable the log.

  • true: Enable the log. Print log at exit.

  • :quiet: Enable the log. Do not print log at exit.

Load extra data embed into binary format String object.

When there is an invalid block with a keyword missing an end right before another end, it is unclear where which keyword is missing the end

Take this example:

class Dog       # 1
  def bark      # 2
    puts "woof" # 3
end             # 4

However due to github.com/ruby/syntax_suggest/issues/32 the problem line will be identified as:

> class Dog       # 1

Because lines 2, 3, and 4 are technically valid code and are expanded first, deemed valid, and hidden. We need to un-hide the matching end line 4. Also work backwards and if there’s a mis-matched keyword, show it too
