Returns the Base64-encoded version of bin. This method complies with RFC 4648. No line feeds are added.
Returns the Base64-decoded version of str. This method complies with RFC 4648. ArgumentError is raised if str is incorrectly padded or contains non-alphabet characters. Note that CR or LF are also rejected.
Returns an Array of option names of the method mid.
p FileUtils.options_of(:rm) #=> ["noop", "verbose", "force"]
Takes a hash as its argument. The key is a symbol or an array of symbols. These symbols correspond to method names. The value is the accessor to which the methods will be delegated.
Tests for the presence of a --with-config or --without-config option. Returns true if the with option is given, false if the without option is given, and the default value otherwise.
This can be useful for adding custom definitions, such as debug information.
Example:
if with_config("debug") $defs.push("-DOSSL_DEBUG") unless $defs.include? "-DOSSL_DEBUG" end
Tests for the presence of an --enable-config or --disable-config option. Returns true if the enable option is given, false if the disable option is given, and the default value otherwise.
This can be useful for adding custom definitions, such as debug information.
Example:
if enable_config("debug") $defs.push("-DOSSL_DEBUG") unless $defs.include? "-DOSSL_DEBUG" end
Sets a target name that the user can then use to configure various “with” options with on the command line by using that name. For example, if the target is set to “foo”, then the user could use the --with-foo-dir=prefix, --with-foo-include=dir and --with-foo-lib=dir command line options to tell where to search for header/library files.
You may pass along additional parameters to specify default values. If one is given it is taken as default prefix, and if two are given they are taken as “include” and “lib” defaults in that order.
In any case, the return value will be an array of determined “include” and “lib” directories, either of which can be nil if no corresponding command line option is given when no default value is specified.
Note that dir_config only adds to the list of places to search for libraries and include files. It does not link the libraries into your application.
Returns compile/link information about an installed library in a tuple of [cflags, ldflags, libs], by using the command found first in the following commands:
If --with-{pkg}-config={command} is given via command line option: {command} {option}
{pkg}-config {option}
pkg-config {option} {pkg}
Where {option} is, for instance, --cflags.
The values obtained are appended to +$CFLAGS+, +$LDFLAGS+ and +$libs+.
If an option argument is given, the config command is invoked with the option and a stripped output string is returned without modifying any of the global values mentioned above.
Creates a new MonitorMixin::ConditionVariable associated with the receiver.
The path to standard location of the user’s .gemrc file.
Attempts to activate the current {#possibility} (given that it has already been activated) @return [void]
True if the gems in the system satisfy dependency.
Returns the destination encoding name as a string.
Returns the destination encoding name as a string.
Perform hostname verification following RFC 6125.
This method MUST be called after calling connect to ensure that the hostname of a remote peer has been verified.
Initiates the SSL/TLS handshake as a client in non-blocking manner.
# emulates blocking connect begin ssl.connect_nonblock rescue IO::WaitReadable IO.select([s2]) retry rescue IO::WaitWritable IO.select(nil, [s2]) retry end
By specifying ‘exception: false`, the options hash allows you to indicate that connect_nonblock should not raise an IO::WaitReadable or IO::WaitWritable exception, but return the symbol :wait_readable or :wait_writable instead.
Builds extensions. Valid types of extensions are extconf.rb files, configure scripts and rakefiles or mkrf_conf files.
