  • Is a string formatter that pulls variables from its calling scope bad practice?

    - by Eric
    I have some code that does an awful lot of string formatting, Often, I end up with code along the lines of: "...".format(x=x, y=y, z=z, foo=foo, ...) Where I'm trying to interpolate a large number of variables into a large string. Is there a good reason not to write a function like this that uses the inspect module to find variables to interpolate? import inspect def interpolate(s): return s.format(**inspect.currentframe().f_back.f_locals) def generateTheString(x): y = foo(x) z = x + y # more calculations go here return interpolate("{x}, {y}, {z}")

  • directory_map() not working outside of application

    - by iamdadude
    Is there a reason as to why $map = directory_map('./', TRUE); works perfectly and, $map = directory_map('../', TRUE); doesn’t work at all? I tried creating a directory with the basic mkdir(); PHP function (http://php.net/mkdir) and it didn’t work either. Can anyone set me in the right direction as to what I’m doing wrong and how I can fix it? Thanks!

  • Beginner question about getting reference to cin

    - by John C
    I'm having problems wrapping my head around this. I have a function void foo(istream& input) { input = cin; } This fails (I'm assuming because cin isn't supposed to be "copyable". however, this works void foo(istream& input) { istream& baz = cin; } Is there a reason that I can get a reference to cin in baz but I cannot assign it to input? Thanks

  • Using functions and environments

    - by Eduardo Leoni
    Following the recent discussions here (e.g. 1, 2 ) I am now using environments in some of my code. My question is, how do I create functions that modify environments according to its arguments? For example: y <- new.env() with(y, x <- 1) f <- function(env,z) { with(env, x+z) } f(y,z=1) throws Error in eval(expr, envir, enclos) : object 'z' not found I am using environments to keep concurrently two sets of simulations apart (without refactoring my code, which I wrote for a single set of experiments).

  • How can I animate multiple elements sequentially using jQuery?

    - by lorenzium
    I thought it would be simple but I still can't get it to work. By clicking one button, I want several animations to happen - one after the other - but now all the animations are happening at once. Here's my code - can someone please tell me where I'm going wrong?: $(".button").click(function(){ $("#header").animate({top: "-50"}, "slow") $("#something").animate({height: "hide"}, "slow") $("ul#menu").animate({top: "20", left: "0"}, "slow") $(".trigger").animate({height: "show", top: "110", left: "0"}, "slow"); });

  • C# Different class objects in one list

    - by jeah_wicer
    I have looked around some now to find a solution to this problem. I found several ways that could solve it but to be honest I didn't realize which of the ways that would be considered the "right" C# or OOP way of solving it. My goal is not only to solve the problems but also to develop a good set of code standards and I'm fairly sure there's a standard way to handle this problem. Let's say I have 2 types of printer hardwares with their respective classes and ways of communicating: PrinterType1, PrinterType2. I would also like to be able to later on add another type if neccessary. One step up in abstraction those have much in common. It should be possible to send a string to each one of them as an example. They both have variables in common and variables unique to each class. (One for instance communicates via COM-port and has such an object, while the other one communicates via TCP and has such an object). I would however like to just implement a List of all those printers and be able to go through the list and perform things as "Send(string message)" on all Printers regardless of type. I would also like to access variables like "PrinterList[0].Name" that are the same for both objects, however I would also at some places like to access data that is specific to the object itself (For instance in the settings window of the application where the COM-port name is set for one object and the IP/port number for another). So, in short something like: In common: Name Send() Specific to PrinterType1: Port Specific to PrinterType2: IP And I wish to, for instance, do Send() on all objects regardless of type and the number of objects present. I've read about polymorphism, Generics, interfaces and such, but I would like to know how this, in my eyes basic, problem typically would be dealt with in C# (and/or OOP in general). I actually did try to make a base class, but it didn't quite seem right to me. For instance I have no use of a "string Send(string Message)" function in the base class itself. So why would I define one there that needs to be overridden in the derived classes when I would never use the function in the base class ever in the first place? I'm really thankful for any answers. People around here seem very knowledgeable and this place has provided me with many solutions earlier. Now I finally have an account to answer and vote with too. EDIT: To additionally explain, I would also like to be able to access the objects of the actual printertype. For instance the Port variable in PrinterType1 which is a SerialPort object. I would like to access it like: PrinterList[0].Port.Open() and have access to the full range of functionality of the underlaying port. At the same time I would like to call generic functions that work in the same way for the different objects (but with different implementations): foreach (printer in Printers) printer.Send(message)

  • How do I hide an HTML element before the page loads

    - by Robert
    I have some JQuery code that shows or hides a div. $("div#extraControls").show(); // OR .hide() I initially want the div to be not visible so I used: $(document).ready(function() { $("div#extraControls").hide(); }); However, on the browser, the content loads visible for a second before disappearing, which is not what I want. How do I set the hide the element before the page loads whilst keeping the ability to show hide it dynamically with a script?

  • How do I pass a javascript parameter to an asp.net MVCmodel from within a View?

    - by Josh
    Hi everyone! I am having an issue trying to access a list property on a model from within a javascript. My basic situation is this: I have an ArticleController and an ArticleViewModel. An Article has a number of properties, one of which is Text, which is just a string that contains the contents of the article. The ArticleViewModel contains a Pages property, which is just a List of Strings. When the ArticleViewModel constructor is called, I populate the Pages list by dividing up the article text based on some delimeters. I have a View which inherits the ArticleViewModel type. What I want to do is only display one page at a time, and then when the user clicks a page number (from a list at the bottom of the article), I want to use javascript to load that page into the #dynamicContent div. The problem: I can't seem to pass a parameter to the Model.Pages property from within javascript... Is this possible? I get an error stating, "Expression Expected" when I try what I have below. I don't want to have to worry about AJAX calls or anything like that since I already have the entire article... I just need a way to access each individual page from within the javascript function. Alternatively, if there is a better solution for "paginating" an article so that I can load each articlePage without having to refresh the entire html page, I would certainly be open to that as well. Any help would be much appreciated!! Thanks for your time! ArticleView Code: Script at the top of the view: function loadPage(pageNumber) { try { alert(pageNumber); $('#dynamicContent').html('<%=Model.Pages(' + pageNumber + ') %>'); } catch (e) { alert('in here'); alert(e.description); } } HTML for view: [...] <div id="articleBody"> <div id="dynamicContent"> <%=Model.Pages(0)%> </div> </div> [...] Page Links at bottom of page: [...] <div> <ul style="display:block"> <li style="display:inline"> <a href="#articleTitle" onclick="loadPage(0)"> 1 </a> </li> <li style="display:inline"> <a href="#articleTitle" onclick="loadPage(1)"> 2 </a> </li> </ul> </div>

  • Resizing Grid Views On Window Resize

I could make a function that detects window resize and then changes the size of each grid view but that feels a bit clunky. Is there not an easier/more intelligent way to do this
