Options for how prism should parse/lex the source.
returns the directory nesting of the extension, ignoring the first part, so “ext/foo/bar/Cargo.toml” becomes “foo/bar”
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.
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("/tmp/hello.rb") #=> <RubyVM::InstructionSequence:<main>@/tmp/hello.rb>
Compile any kind of node. Dispatch out to the individual compilation methods based on the type of node.
Removes installed executables and batch files (windows only) for spec.
returns a Time that represents the Last-Modified field.
Add the install/update options to the option parser.
Add the –update-sources option
Unpacks sockaddr into path.
sockaddr should be a string or an addrinfo for AF_UNIX.
sockaddr = Socket.sockaddr_un("/tmp/sock") p Socket.unpack_sockaddr_un(sockaddr) #=> "/tmp/sock"
Counts objects size (in bytes) for each type.
Note that this information is incomplete. You need to deal with this information as only a HINT. Especially, total size of T_DATA may be wrong.
It returns a hash as:
{:TOTAL=>1461154, :T_CLASS=>158280, :T_MODULE=>20672, :T_STRING=>527249, ...}
If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.
The contents of the returned hash is implementation defined. It may be changed in future.
This method is only expected to work with C Ruby.
Counts objects for each T_DATA type.
This method is only for MRI developers interested in performance and memory usage of Ruby programs.
It returns a hash as:
{RubyVM::InstructionSequence=>504, :parser=>5, :barrier=>6,
:mutex=>6, Proc=>60, RubyVM::Env=>57, Mutex=>1, Encoding=>99,
ThreadGroup=>1, Binding=>1, Thread=>1, RubyVM=>1, :iseq=>1,
Random=>1, ARGF.class=>1, Data=>1, :autoload=>3, Time=>2}
# T_DATA objects existing at startup on r32276.
If the optional argument, result_hash, is given, it is overwritten and returned. This is intended to avoid probe effect.
The contents of the returned hash is implementation specific and may change in the future.
In this version, keys are Class object or Symbol object.
If object is kind of normal (accessible) object, the key is Class object. If object is not a kind of normal (internal) object, the key is symbol name, registered by rb_data_type_struct.
This method is only expected to work with C Ruby.
The number of paths in the +$LOAD_PATH+ from activated gems. Used to prioritize -I and ENV['RUBYLIB'] entries during require.
Returns the latest release version of RubyGems.
Returns the version of the latest release-version of gem name
