The logical inverse of ‘capture_last_end_same_indent`
When there is an invalid block with an ‘end` missing a keyword right after another `end`, it is unclear where which end is missing the keyword.
Take this example:
class Dog # 1
puts "woof" # 2
end # 3
end # 4
the problem line will be identified as:
> end # 4
This happens because lines 1, 2, and 3 are technically valid code and are expanded first, deemed valid, and hidden. We need to un-hide the matching keyword on line 1. Also work backwards and if there’s a mis-matched end, show it too
Like Enumerable#select, but chains operation to be lazy-evaluated.
If a block is given, returns a lazy enumerator that will iterate over the given block for each element with an index, which starts from offset, and returns a lazy enumerator that yields the same values (without the index).
If a block is not given, returns a new lazy enumerator that includes the index, starting from offset.
offset
the starting index to use
Return the block length of the digest in bytes.
Return the block length of the digest in bytes.
Digest::SHA256.new.block_length * 8 # => 512 Digest::SHA384.new.block_length * 8 # => 1024 Digest::SHA512.new.block_length * 8 # => 1024
Returns the Fiddle::Pointer of this handle.
Get the underlying pointer for ruby object val and return it as a Fiddle::Pointer object.
Returns the integer memory location of this pointer.
Generates a cryptographically strong pseudo-random number in the range 0…range.
See also the man page BN_rand_range(3).
Generates a random prime number of bit length bits. If safe is set to true, generates a safe prime. If add is specified, generates a prime that fulfills condition p % add = rem.
