Yes. Please see the man page of Bash (the first thing you go to) under Special Parameters: Special Parameters The shell treats several parameters specially. These parameters may only be referenced; assignment to them is not allowed. * Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands … Read more
There are two related concepts, both called “keyword arguments“. On the calling side, which is what other commenters have mentioned, you have the ability to specify some function arguments by name. You have to mention them after all of the arguments without names (positional arguments), and there must be default values for any parameters which … Read more
Actually, there appears to now be a simple way. The following code works in TypeScript 1.5: function sayName({ first, last=”Smith” }: {first: string; last?: string }): void { const name = first + ‘ ‘ + last; console.log(name); } sayName({ first: ‘Bob’ }); The trick is to first put in brackets what keys you want … Read more
Wow, everybody is such a pessimist around here. The answer is yes. It ain’t trivial: by the end, we’ll have the core function, a supporting struct, a wrapper function, and a macro around the wrapper function. In my work I have a set of macros to automate all this; once you understand the flow it’ll … Read more
Use –build-arg with each argument. If you are passing two argument then add –build-arg with each argument like: docker build \ -t essearch/ess-elasticsearch:1.7.6 \ –build-arg number_of_shards=5 \ –build-arg number_of_replicas=2 \ –no-cache .
There are many ways to do this. To fix your current code using %-formatting, you need to pass in a tuple: Pass it as a tuple: print(“Total score for %s is %s” % (name, score)) A tuple with a single element looks like (‘this’,). Here are some other common ways of doing it: Pass it … Read more
As far as I can tell after reading the docs for javadoc there is no such feature. Don’t use <code>foo</code> as recommended in other answers; you can use {@code foo}. This is especially good to know when you refer to a generic type such as {@code Iterator<String>} — sure looks nicer than <code>Iterator<String></code>, doesn’t it!
Just use the *args parameter, which allows you to pass as many arguments as you want after your a,b,c. You would have to add some logic to map args->c,d,e,f but its a “way” of overloading. def myfunc(a,b, *args, **kwargs): for ar in args: print ar myfunc(a,b,c,d,e,f) And it will print values of c,d,e,f Similarly you … Read more
ES6 using rest parameters If you are able to use ES6 you can use: Rest Parameters function sortArgs(…args) { return args.sort(function (a, b) { return a – b; }); } document.body.innerHTML = sortArgs(12, 4, 6, 8).toString(); As you can read in the link The rest parameter syntax allows us to represent an indefinite number of … Read more
In Python, this: my_object.method(“foo”) …is syntactic sugar, which the interpreter translates behind the scenes into: MyClass.method(my_object, “foo”) …which, as you can see, does indeed have two arguments – it’s just that the first one is implicit, from the point of view of the caller. This is because most methods do some work with the object … Read more
