It's relatively easy to parse the command line by hand if you aren't looking for anything too complex: # Naive error checking abort('Usage: ' + $0 + ' site id ...') unless ARGV.length >= 2 # First item (site) is mandatory site = ARGV.shift ARGV.each do | id | # Do something interestin...

With OptionsParser, it's really easy to set up default values. Just pre-populate the hash you store the options in: options = { :directory => ENV['HOME'] } When you define the parser, it will overwrite the default if a user provide a value: OptionParser.new do |opts| opts.on("-d&...

Suppose you had an array: pair = ['Jack','Jill'] And a method that takes two arguments: def print_pair (a, b) puts "#{a} and #{b} are a good couple!" end You might think you could just pass the array: print_pair(pair) # wrong number of arguments (1 for 2) (ArgumentError) Si...

The splat operator removes individual elements of an array and makes them into a list. This is most commonly used to create a method that accepts a variable number of arguments: # First parameter is the subject and the following parameters are their spouses def print_spouses(person, *spouses) s...

The ValuesAttribute is used to specify a set of values for an individual parameter of a test method with parameters. [Test] public void Sum_Works_Correctly( [Values(1, 2, 3)] int x, [Values(4, 5)] int y) { // Arrange var calculator = new Calculator(...

By setting Multi-Release: true in the MANIFEST.MF file, the Jar file becomes a multi-release Jar and the Java runtime (as long as it supports the MRJAR format) will pick the appropriate versions of classes depending on the current major version. The structure of such a Jar is the following: jar ro...

The jar command can be used to create a multi-release Jar containing two versions of the same class compiled for both Java 8 and Java 9, albeit with a warning telling that the classes are identical: C:\Users\manouti>jar --create --file MR.jar -C sampleproject-base demo --release 9 -C sampleproje...

Given the following multi-release Jar: jar root - demo - SampleClass.class - META-INF - versions - 9 - demo - SampleClass.class The following class prints the URL of the SampleClass: package demo; import java.net.URL; public class Main...

The following prints all stack frames of the current thread: 1 package test; 2 3 import java.lang.StackWalker.StackFrame; 4 import java.lang.reflect.InvocationTargetException; 5 import java.lang.reflect.Method; 6 import java.util.List; 7 import java.util.stream.Collectors; 8 9 pu...

The following prints the current caller class. Note that in this case, the StackWalker needs to be created with the option RETAIN_CLASS_REFERENCE, so that Class instances are retained in the StackFrame objects. Otherwise an exception would occur. public class StackWalkerExample { public stat...

A couple of other options allow stack traces to include implementation and/or reflection frames. This may be useful for debugging purposes. For instance, we can add the SHOW_REFLECT_FRAMES option to the StackWalker instance upon creation, so that the frames for the reflective methods are printed as ...
