Results for: "fnmatch"

Like Enumerable#map, but chains operation to be lazy-evaluated.

(1..Float::INFINITY).lazy.map {|i| i**2 }
#=> #<Enumerator::Lazy: #<Enumerator::Lazy: 1..Infinity>:map>
(1..Float::INFINITY).lazy.map {|i| i**2 }.first(3)
#=> [1, 4, 9]

Like Enumerable#chunk, but chains operation to be lazy-evaluated.

Iterates over the elements of the first enumerable by calling the “each” method on it with the given arguments, then proceeds to the following enumerables in sequence until all of the enumerables are exhausted.

If no block is given, returns an enumerator.

Update the digest using given string and return self.

Update the digest using a given string and return self.

Allocates a C struct with the types provided.

See Fiddle::Pointer.malloc for memory management issues.

Examples

# Automatically freeing the pointer when the block is exited - recommended
Fiddle::Pointer.malloc(size, Fiddle::RUBY_FREE) do |pointer|
  ...
end

# Manually freeing but relying on the garbage collector otherwise
pointer = Fiddle::Pointer.malloc(size, Fiddle::RUBY_FREE)
...
pointer.call_free

# Relying on the garbage collector - may lead to unlimited memory allocated before freeing any, but safe
pointer = Fiddle::Pointer.malloc(size, Fiddle::RUBY_FREE)
...

# Only manually freeing
pointer = Fiddle::Pointer.malloc(size)
begin
  ...
ensure
  Fiddle.free pointer
end

# No free function and no call to free - the native memory will leak if the pointer is garbage collected
pointer = Fiddle::Pointer.malloc(size)
...

Allocate size bytes of memory and associate it with an optional freefunc.

If a block is supplied, the pointer will be yielded to the block instead of being returned, and the return value of the block will be returned. A freefunc must be supplied if a block is.

If a freefunc is supplied it will be called once, when the pointer is garbage collected or when the block is left if a block is supplied or when the user calls call_free, whichever happens first. freefunc must be an address pointing to a function or an instance of Fiddle::Function.

Encrypts data in a streaming fashion. Hand consecutive blocks of data to the update method in order to encrypt it. Returns the encrypted data chunk. When done, the output of Cipher#final should be additionally added to the result.

If buffer is given, the encryption/decryption result will be written to it. buffer will be resized automatically.

Indicated whether this Cipher instance uses an Authenticated Encryption mode.

Not every message digest can be computed in one single pass. If a message digest is to be computed from several subsequent sources, then each may be passed individually to the Digest instance.

Example

digest = OpenSSL::Digest.new('SHA256')
digest.update('First input')
digest << 'Second input' # equivalent to digest.update('Second input')
result = digest.digest

Returns hmac updated with the message to be authenticated. Can be called repeatedly with chunks of the message.

Example

first_chunk = 'The quick brown fox jumps '
second_chunk = 'over the lazy dog'

instance.update(first_chunk)
#=> 5b9a8038a65d571076d97fe783989e52278a492a
instance.update(second_chunk)
#=> de7c9b85b8b78aa6bc8a7a36f70a90701c9db4d9

Retrieves the section and its pairs for the current configuration.

config.each do |section, key, value|
  # ...
end

Parameters

• pass - string

• name - A string describing the key.

• key - Any PKey.

• cert - A X509::Certificate.

  • The public_key portion of the certificate must contain a valid public key.

  • The not_before and not_after fields must be filled in.

• ca - An optional array of X509::Certificate‘s.

• key_pbe - string

• cert_pbe - string

• key_iter - integer

• mac_iter - integer

• keytype - An integer representing an MSIE specific extension.

Any optional arguments may be supplied as nil to preserve the OpenSSL defaults.

See the OpenSSL documentation for PKCS12_create().

Convert path string to a class

Emit a map. The coder will be yielded to the block.
