GetCommandLine linux *true* equivalent

Similar question to Linux equivalent of GetCommandLine and CommandLineToArgv Is it possible to get the raw command line in linux? The file /proc/self/cmdline is destroyd. ./a.out files="file 1","file 2" param="2" prints ./a.outfiles=file 1,file 2param=2 which is junk Escaping command line does work for all arguments but the first. ./a.out files=\"fil 1\",\"fil 2\"\ param=\"2\" prints ./a.outfiles="fil1","fil2" param="2" You can't do that. The command line arguments are actually passed to the new process as individual strings. See the linux kernel source: kernel_execve Note that kernel_execve(.

.NET code execution at normal process exit?

问题 In C there is the atexit function, which The atexit() function registers the given function to be called at normal process termination, either via exit(3) or via return from the program's main(). Python has a similar capability. Does .NET provide a way to call code at normal process termination? I know there are certain things like DomainUnload and ProcessExit , but at least as far as I can tell, these are unreliable - either requiring the application to be a Windows Forms (or WPF app), or

JavaScript equivalent of SwingUtilities.invokeLater()

Is there any equivalent of Java's invokeLater() method of SwingUtilities in Javascript? UPDATE 1 So, will setTimeout() with zero delay do exactly the same as invokeLater() ? Tomasz Nurkiewicz If you want to run something asynchronously ( later ), try setTimeout() JavaScript is single-threaded. If you want to run some time consuming (CPU-intensive) task outside of the event handler, you can do this using the technique above, however it will still consume event-handling thread (cause your UI to freeze). It is generally a bad idea to run CPU-intensive tasks inside a browser ( web workers might

What is the C# equivalent of CType in VB.NET?

I am trying to convert the example provided in MSDN article Creating Dynamic Data Entry User Interfaces to C#, but am stuck at the following code: CType(dq, IUIBuildingBlock).QuestionText = reader("QuestionText") How do I convert the above VB.NET statement to C#? In C#, you can specify a cast by putting the type you want to cast to in parenthesis in front of the reference variable that you want to cast ( (type)instance ). So, to cast the object ( dq ) to the type IUIBuildingBlock , you could use the following code: ((IUIBuildingBlock)dq).QuestionText = reader("QuestionText"); (Note that this

PHP equivalent of send and getattr?

If Ruby gets invited to a party and brings: foobarobject.send('foomethod') .. and Python gets invited to the same party and brings: getattr(foobarobject, 'foomethod')() .. what does PHP have to bring to the party? Bonus question: If Ruby and Python got jealous of PHP's party-favors, what English terms would they search for in PHP's documentation in order to talk about it behind PHP's back? PHP brings this: $foobarobject->{"foomethod"}(); ... and the coke and chips. EDIT : Although the term for the above is variable variables there is nothing specifically talking about doing it to an object in

TypeError: list indices must be integers or slices, not list

array = some kind of list with 3 columns and unlimited amount of rows with data inside of it. Volume = array[0][2] counter = 0 for i in array: if Volume == array[i][2]: #<------ why is this line a problem? counter += 1 This is a classic mistake. i in your case is already an element from array (i.e. another list), not an index of array ( not an int ), so if Volume == i[2]: counter += 1 Please, make sure to go at least through the beginning of Python tutorial , because this is very simple and fundamental stuff. Also I would advise to stick to naming conventions: variables are normally lower-case

问题 Is there a pure JS equivalent of jQuery .is() on modern browsers? I know there is the querySelector method, but I want to check the node itself, rather than finding child nodes. 回答1: Looks like matchesSelector is what I want. https://developer.mozilla.org/en-US/docs/Web/API/Element.matches Polyfill is here: https://gist.github.com/jonathantneal/3062955 this.Element && function(ElementPrototype) { ElementPrototype.matchesSelector = ElementPrototype.matchesSelector || ElementPrototype

Readable C# equivalent of Python slice operation

What is the C# equivalent of Python slice operations? my_list = ['a', 'b', 'c', 'd', 'e', 'f', 'g'] result1 = my_list[2:4] result2 = my_list[1:] result3 = my_list[:3] result4 = my_list[:3] + my_list[4:] Some of it is covered here , but it is ugly and doesn't address all the uses of slicing to the point of it not obviously answering the question. Ben The closest is really LINQ .Skip() and .Take() Example: var result1 = myList.Skip(2).Take(2); var result2 = myList.Skip(1); var result3 = myList.Take(3); var result4 = myList.Take(3).Concat(myList.Skip(4)); As of C#8 slicing becomes a lot easier
