GNU Makefile rule generating a few targets from a single source file
I am attempting to do the following. There is a program, call it foo-bin , that takes in a single input file and generates two output files. A dumb Makefile rule for this would be:
...
Assert equals between 2 Lists in Junit
... values and nothing else, in order as stated in the javadoc.
Suppose a Foo class where you add elements and where you can get that.
A unit test of Foo that asserts that the two lists have the same content could look like :
import org.assertj.core.api.Assertions;
import org.junit.jupiter.api.Tes...
Pass a JavaScript function as parameter
...s a function, just reference it by name without the parentheses:
function foo(x) {
alert(x);
}
function bar(func) {
func("Hello World!");
}
//alerts "Hello World!"
bar(foo);
But sometimes you might want to pass a function with arguments included, but not have it called until the callback...
Can I export a variable to the environment from a bash script without sourcing it?
...he script in the context of the calling shell:
$ cat set-vars1.sh
export FOO=BAR
$ . set-vars1.sh
$ echo $FOO
BAR
Another way is to have the script, rather than setting an environment variable, print commands that will set the environment variable:
$ cat set-vars2.sh
#!/bin/bash
echo export FO...
How to reference a method in javadoc?
...Method in the same class:
/** See also {@link #myMethod(String)}. */
void foo() { ... }
Method in a different class, either in the same package or imported:
/** See also {@link MyOtherClass#myMethod(String)}. */
void foo() { ... }
Method in a different package and not imported:
/** See also {@l...
How to set the prototype of a JavaScript object that has already been instantiated?
Suppose I have an object foo in my JavaScript code. foo is a complex object and it is generated somewhere else. How can I change the prototype of the foo object?
...
What is the curiously recurring template pattern (CRTP)?
...e polymorphism. Here's a very simple example. In the below example, ProcessFoo() is working with Base class interface and Base::Foo invokes the derived object's foo() method, which is what you aim to do with virtual methods.

Cannot pass null argument when using type hinting
...ou can explicitly declare a variable to be null with this syntax
function foo(?Type $t) {
}
this will result in
$this->foo(new Type()); // ok
$this->foo(null); // ok
$this->foo(); // error
So, if you want an optional argument you can follow the convention Type $t = null whereas if you...

Can someone explain __all__ in Python?
...> import * is used on the module.
For example, the following code in a foo.py explicitly exports the symbols bar and baz:
__all__ = ['bar', 'baz']
waz = 5
bar = 10
def baz(): return 'baz'
These symbols can then be imported like so:
from foo import *
print(bar)
print(baz)
