A shell function could help on this: [alias] files = “!f() { git diff –name-status \”$1^\” \”$1\”; }; f” An alias without ! is treated as a Git command; e.g. commit-all = commit -a.

With params you can call your method like this: addTwoEach(1, 2, 3, 4, 5); Without params, you can’t.

Well we don’t actually need inspect here. >>> func = lambda x, y: (x, y) >>> >>> func.__code__.co_argcount 2 >>> func.__code__.co_varnames (‘x’, ‘y’) >>> >>> def func2(x,y=3): … print(func2.__code__.co_varnames) … pass # Other things … >>> func2(3,3) (‘x’, ‘y’) >>> >>> func2.__defaults__ (3,) For Python 2.5 and older, use func_code instead of __code__, and func_defaults … Read more
You need to create an anonymous function so the actual function isn’t executed right away. setInterval( function() { funca(10,3); }, 500 );
In Java args contains the supplied command-line arguments as an array of String objects. In other words, if you run your program in your terminal as : C:/ java MyProgram one two then args will contain [“one”, “two”]. If you wanted to output the contents of args, you can just loop through them like this… … Read more
For ‘out’, the following seems to work for me. public interface IService { void DoSomething(out string a); } [TestMethod] public void Test() { var service = new Mock<IService>(); var expectedValue = “value”; service.Setup(s => s.DoSomething(out expectedValue)); string actualValue; service.Object.DoSomething(out actualValue); Assert.AreEqual(expectedValue, actualValue); } I’m guessing that Moq looks at the value of ‘expectedValue’ when you … Read more
