Add a certificate to trusted certificate list.
Creates a new Socket::Option object for IP_MULTICAST_TTL.
The size is dependent on the platform.
p Socket::Option.ipv4_multicast_ttl(10) #=> #<Socket::Option: INET IP MULTICAST_TTL 10>
Returns the ipv4_multicast_ttl data in sockopt as an integer.
sockopt = Socket::Option.ipv4_multicast_ttl(10) p sockopt.ipv4_multicast_ttl => 10
Creates a new Socket::Option object for IP_MULTICAST_LOOP.
The size is dependent on the platform.
sockopt = Socket::Option.int(:INET, :IPPROTO_IP, :IP_MULTICAST_LOOP, 1) p sockopt.int => 1 p Socket::Option.ipv4_multicast_loop(10) #=> #<Socket::Option: INET IP MULTICAST_LOOP 10>
Returns the ipv4_multicast_loop data in sockopt as an integer.
sockopt = Socket::Option.ipv4_multicast_loop(10) p sockopt.ipv4_multicast_loop => 10
Takes file, a String with the location of a Ruby source file, reads, parses and compiles the file, and returns iseq, the compiled InstructionSequence with source location metadata set. It parses and compiles using prism.
Optionally takes options, which can be true, false or a Hash, to modify the default behavior of the Ruby iseq compiler.
For details regarding valid compile options see ::compile_option=.
# /tmp/hello.rb puts "Hello, world!" # elsewhere RubyVM::InstructionSequence.compile_file_prism("/tmp/hello.rb") #=> <RubyVM::InstructionSequence:<main>@/tmp/hello.rb>
Returns the offset from the start of the file for the given byte offset counting in code units for the given encoding.
This method is tested with UTF-8, UTF-16, and UTF-32. If there is the concept of code units that differs from the number of characters in other encodings, it is not captured here.
We purposefully replace invalid and undefined characters with replacement characters in this conversion. This happens for two reasons. First, it’s possible that the given byte offset will not occur on a character boundary. Second, it’s possible that the source code will contain a character that has no equivalent in the given encoding.
Generate a cache that targets a specific encoding for calculating code unit offsets.
Returns the offset from the start of the file for the given byte offset counting in code units for the given encoding.
This method is tested with UTF-8, UTF-16, and UTF-32. If there is the concept of code units that differs from the number of characters in other encodings, it is not captured here.
Returns a cache that is the identity function in order to maintain the same interface. We can do this because code units are always equivalent to byte offsets for ASCII-only sources.
The character offset from the beginning of the source where this location starts.
The content of the line where this location starts before this location.
The column number in characters where this location ends from the start of the line.
Create a code units cache for the given encoding.
