  • Iterating through struct fieldnames in MATLAB.

    - by Noio
    My question is easily summarized as: "Why does the following not work?" teststruct = struct('a',3,'b',5,'c',9) fields = fieldnames(teststruct) for i=1:numel(fns) fns(i) teststruct.(fns(i)) end output: ans = 'a' ??? Argument to dynamic structure reference must evaluate to a valid field name. Especially since teststruct.('a') does work. And fns(i) prints out ans = 'a'. I can't get my head around it.

  • Check directory for files, retrieve first file

    - by Lowgain
    I'm writing a small ruby daemon that I am hoping will do the following: Check if a specific directory has files (in this case, .yml files) If so, take the first file (numerically sorted preferrably), and parse into a hash Do a 'yield', with this hash as the argument What I have right now is like: loop do get_next_in_queue { |s| THINGS } end def get_next_in_queue queue_dir = Dir[File.dirname(__FILE__)+'/../queue'] info = YAML::load_file(queue_dir[0]) #not sure if this works or not yield info end I'd like to make the yield conditional if possible, so it only happens if a file is actually found. Thanks!

  • C++ Pass a hidden arg to a class constructor?

    - by JP
    I would like to define a class that accept the pointer to it's parent class as an Argument, but would it be possible to somehow pass it without needing to pass it directly such as: class Child { public: Child(Parent* hiddenArg); }; class Parent { public: Child myChild; }; I know this is weird, but I am making my own Signal/Slot implementation and Child would be a signal defined, but I would like to get the parent so I can use it's Event Dispatcher...

I think It should be in following manner but problem is to pass argument. var availItem = { xs : xs, s : s, m : m, l : l, xl : xl }

  • Does a syntax for this exist? In any language?

    - by Michael
    It seems pretty common to me to have an argument, in a dynamically typed language that is either an Object or a key to lookup that object. For instance when I'm working with a database I might have a method getMyRelatedStuff(person) All I really need to lookup the related stuff is the id of the person so my method could look like this in python: def getMyRelatedStuff(person_or_id): id = person_or_id.id if isinstance(person,User) else person_or_id #do some lookup Or going the other direction: def someFileStuff(file_or_name): file = file_or_name if hasattr(file,'write') else open(file_or_name)

  • VIM plugin for updating C++ function definition

    - by Sunny
    I'm looking for a VIM plugin that can do these kind of thing. Let's say I have a function in a .cpp file void myFunction(int arg1, int arg2, int arg3){ //code } The function definition is defined in the .h file. So every time I change the function name or add a new argument to the function, I have to go back the the .h file to do the same. Is there a VIM plugin that can automate this task?

  • Get a list/tuple/dict of *all* the arguments passed to a function?

    - by Phillip Oldham
    Given the following function: def foo(a, b, c): pass How would one obtain a list/tuple/dict/etc of the arguments passed in? Specifically, I'm looking for Python's version of JavaScript's arguments keyword or PHP's func_get_args() method. What I'm not looking for is a solution using *args or **kwargs; I need to specify the argument names in the function definition (to ensure they're being passed in) but within the function I want to work with them in a list- or dict-style structure.

  • Regex to find A and not B on a line

    - by Zach
    I'm looking for a regex to search my python program to find all lines where foo, but not bar, is passed into a method as a keyword argument. I'm playing around with lookahead and lookbehind assertions, but not having much luck. Any help? Thanks

  • Resharper intellisense confusion

    - by Mystere Man
    Today I had something weird happen in my copy of Resharper 5. I have a class that looks like this: public class Foo { public string Username { get; private set; } public Foo (string userName) { Username = userName; } public void Bar() { DoWork(Username); } public DoWork(string userName) { } } When I start to type DoWork(us I get the following from intellisense: Notice that it's pulling up the constructor argument, and it ends with a colon: userName: What's going on here?

  • SeFocus causing Run time error

    - by code8230
    I am getting: Run-time error '5': Invalid procedure call or argument this seems to happen when Text(1).SetFocus is called. However, I dont see this run time error for all the cases where I have used SetFocus. Just 2-3 places it is causing this error. Text(1).SelStart = 3 Text(1).SelLength = 1 Text(1).SetFocus I tried: Text(1).Enabled = True Text(1).Visible = True just above .SelStart, but it didn't fix the issue.

  • Java slick command line app?

    - by Felix
    Hello Guys, I want to make a slick java commandline app which doesnt include all the nasty "java -jar some.jar arguments" instead, I would have it work just like program -option argument like any other commandline app. I use ubuntu linux, and it would be fine if it included a bit of .sh script or anything. I know I can just create a file with java -jar program.jar and do chmod +x file, afterwards I could run i with ./file, but then how can I pass the arguments to the program ?

  • how can I get around no arrays as class constants in php?

    - by user151841
    I have a class with a static method. There is an array to check that a string argument passed is a member of a set. But, with the static method, I can't reference the class property in an uninstantiated class, nor can I have an array as a class constant. I suppose I could hard code the array in the static method, but then if I need to change it, I'd have to remember to change it in two places. I'd like to avoid this.

  • Java, user input to the command line when using Runtime.getRuntime().exec(command);

    - by user1557354
    I dont think this is possible, but I have been using: Process p = Runtime.getRuntime().exec(command); to run commands on the command line, but now I have come accross a situation where the command I am running part way through will ask for some user input, for example a username. This can not be resolved by a argument to the command that is being exec, is there any way I can pass the username to the same command line instance and continue? Thanks in advance.

  • Parsing command line options in Perl

    - by Jay Gridley
    Hi guys, I am parsing command line options in Perl using Getopt::Long. I am forced to use prefix - (one dash) for short commands (-s) and -- (double dash) for long commands (ex. --input=file), but problem is, that there is one special option (-r=) so it is long option for its requirement for argument, but it has to have one dash (-) prefix not double dash (--) like other long options. Is possible to setup Getopt::Long to accept these?
