Start a dRuby server locally.
The new dRuby server will become the primary server, even if another server is currently the primary server.
uri is the URI for the server to bind to. If nil, the server will bind to random port on the default local host name and use the default dRuby protocol.
front is the server’s front object. This may be nil.
config is the configuration for the new server. This may be nil.
See DRbServer::new.

Get the ‘current’ server.
In the context of execution taking place within the main thread of a dRuby server (typically, as a result of a remote call on the server or one of its objects), the current server is that server. Otherwise, the current server is the primary server.
If the above rule fails to find a server, a DRbServerNotFound error is raised.

Returns true if the contents of files a and b are identical, false otherwise.
Arguments a and b should be interpretable as a path.
FileUtils.identical? and FileUtils.cmp are aliases for FileUtils.compare_file.

Returns whether or not the variable var can be found in the common header files, or within any headers that you provide. If found, a macro is passed as a preprocessor constant to the compiler using the variable name, in uppercase, prepended with HAVE_.
To check variables in an additional library, you need to check that library first using have_library().
For example, if have_var('foo') returned true, then the HAVE_FOO preprocessor macro would be passed to the compiler.
Open3.pipeline_rw starts a list of commands as a pipeline with pipes which connect to stdin of the first command and stdout of the last command.
Open3.pipeline_rw(cmd1, cmd2, ... [, opts]) {|first_stdin, last_stdout, wait_threads|
...
}
first_stdin, last_stdout, wait_threads = Open3.pipeline_rw(cmd1, cmd2, ... [, opts])
...
first_stdin.close
last_stdout.close
Each cmd is a string or an array. If it is an array, the elements are passed to Process.spawn.
cmd: commandline command line string which is passed to a shell [env, commandline, opts] command line string which is passed to a shell [env, cmdname, arg1, ..., opts] command name and one or more arguments (no shell) [env, [cmdname, argv0], arg1, ..., opts] command name and arguments including argv[0] (no shell) Note that env and opts are optional, as for Process.spawn.
The options to pass to Process.spawn are constructed by merging opts, the last hash element of the array, and specifications for the pipes between each of the commands.
Example:
Open3.pipeline_rw("tr -dc A-Za-z", "wc -c") {|i, o, ts| i.puts "All persons more than a mile high to leave the court." i.close p o.gets #=> "42\n" } Open3.pipeline_rw("sort", "cat -n") {|stdin, stdout, wait_thrs| stdin.puts "foo" stdin.puts "bar" stdin.puts "baz" stdin.close # send EOF to sort. p stdout.read #=> " 1\tbar\n 2\tbaz\n 3\tfoo\n" }

The mode needed to read a file as straight binary.
Reset the dir and path values. The next time dir or path is requested, the values will be calculated from scratch. This is mainly used by the unit tests to provide test isolation.
The version of the Marshal format for your Ruby.
Adds a post-installs hook that will be passed a Gem::DependencyInstaller and a list of installed specifications when Gem::DependencyInstaller#install is complete

SyntaxSuggest.handle_error [Public]
Takes a ‘SyntaxError` exception, uses the error message to locate the file. Then the file will be analyzed to find the location of the syntax error and emit that location to stderr.
Example:
begin require 'bad_file' rescue => e SyntaxSuggest.handle_error(e) end
By default it will re-raise the exception unless ‘re_raise: false`. The message output location can be configured using the `io: $stderr` input.
If a valid filename cannot be determined, the original exception will be re-raised (even with ‘re_raise: false`).
