  • JSDoc adding real code in documentation

    - by Marco Demaio
    Do you know if there is a some sort of <code> tag in JSDoc? I need to add pieces of code in mt documentation like this: /** * This function does something see example below: * <p> * var x = foo("test"); //it will show "test" message * * @param {string} str: string argumnet that will be shown in message */ function foo(str) { alert(str); } I need that the code in the comments being displaied by JSDoc as code (if not sintax highlighetd, at least as code like in preformatted or something with grey background) Thanks.

  • How do I temporarily change the require path in Ruby ($:)?

    - by John Feminella
    I'm doing some trickery with a bunch of Rake tasks for a complex project, gradually refactoring away some of the complexity in chunks at a time. This has exposed the bizarre web of dependencies left behind by the previous project maintainer. What I'd like to be able to do is to add a specific path in the project to require's list of paths to be searched, aka $:. However, I only want that path to be searched in the context of one particular method. Right now I'm doing something like this: def foo() # Look up old paths, add new special path. paths = $: $: << special_path # Do work ... bar() baz() quux() # Reset. $:.clear $: << paths end def bar() require '...' # If called from within foo(), will also search special_path. ... end This is clearly a monstrous hack. Is there a better way?

  • routine to generate a 2d array from two 1d arrays and a function

    - by intuited
    I'm guessing that there's a word for this concept, and that it's available in at least some popular languages, but my perfunctory search was fruitless. A pseudocode example of what I'd like to do: function foo(a, b) { return a * b // EG } a = [ 1, 2, 3 ] b = [ 4, 5, 6 ] matrix = the_function_for_which_I_search(foo, [a, b] ) print matrix => [ [ 4, 8, 12], [5, 10, 15], [6, 12, 18] ] // or function concatenate(a,b) return a.b } print the_function_for_which_I_search( concatenate, [ a, b ]) => [ [ '14', '24', '34'], ['15', '25', '35'], [16', '26', '36'] ] In other words, function_for_which_I_search will apply the function given as its first argument to each combination of the elements of the two arrays passed as its second argument, and return the results as a two-dimensional array. I would like to know if such a routine has a common name, and if it's available in a python module, cpan package, ruby gem, pear package, etc. I'm also wondering if this is a core function in other languages, maybe haskell or R?

  • Need help with jQuery UI Accordion navigationFilter option

    - by theJBRU
    I'm building an accordion for navigation. Each section of the accordion has a set of links. The firing code looks like this: $(document).ready(function() { $(".selector").accordion({ collapsible: true, active: false, navigation: true }); }); This all worked fine and dandy until one of the links in each set was edited to point to a single file, call it foo.html. So now if you navigate to foo.html, the location.href matches every section of the accordion (since each section has a link to it) and that opens all the sections, defeating the purpose of the accordion. So I'm pretty sure I need to use the navigationFilter option but I've googled the living hell out of it and haven't found any examples of how to build the function associated with it. Help me, Stack Overflow!

  • Eclipse call hierarchy skips calls in undefined #ifdef regions

    - by stupakov
    Hi all, The "call hierarchy" and "declaration" features in Eclipse CDT omit results that exist in undefined (greyed out) #ifdef regions. Example: void blah(void) { #ifndef ABC foo(); #else //line is greyed out bar(); //line is greyed out #endif //line is greyed out } The call hierarchy for foo() will list blah() as a caller; the call hierarchy for bar() will not list blah(). I'm not expecting it to do full resolution of which #define blocks will get compiled, I simply would like it to return all calls/declarations of the function I'm searching for, regardless of the #define blocks that surround it. Other IDEs such as SlickEdit are able to do this. Does anyone know of a way to get Eclipse to adopt this behavior? Thanks.

  • Modify Address of asmx Method Call

    - by Adam
    When I'm making asmx web service calls from Silverlight, is there any way to have the (generated) SoapClient objects modify the address that they call the service on? Specifically, I'd like to tack on a QueryString value onto each call that the service makes. So if I have DataService.SilverlightServiceSoapClient C = new DataService.SilverlightServiceSoapClient(); Is there any way to do something like: C.Address += "?Foo=Bar"; Which would allow me to, from my WebMethod, say: HttpContext.Current.Request.QueryString["foo"]; Obviously I can modify my WebMethods to take this value in as a parameter, but I'd like to avoid doing that if possible.

  • Why the difference in speed?

    - by AngryHacker
    Consider this code: function Foo(ds as OtherDLL.BaseObj) dim lngRowIndex as long dim lngColIndex as long for lngRowIndex = 1 to ubound(ds.Data, 2) for lngColIndex = 1 to ds.Columns.Count Debug.Print ds.Data(lngRowIndex, lngColIndex) next next end function OK, a little context. Parameter ds is of type OtherDLL.BaseObj which is defined in a referenced ActiveX DLL. ds.Data is a variant 2-dimensional array (one dimension carries the data, the other one carries the column index. ds.Columns is a Collection of columns in 'ds.Data`. Assuming there are at least 400 rows of data and 25 columns, this code takes about 15 seconds to run on my machine. Kind of unbelievable. However if I copy the variant array to a local variable, so: function Foo(ds as OtherDLL.BaseObj) dim lngRowIndex as long dim lngColIndex as long dim v as variant v = ds.Data for lngRowIndex = 1 to ubound(v, 2) for lngColIndex = 1 to ds.Columns.Count Debug.Print v(lngRowIndex, lngColIndex) next next end function the entire thing processes in barely any noticeable time (basically close to 0). Why?

  • Constructing mocks in unit tests

    - by Flynn1179
    Is there any way to have a mock constructed instead of a real instance when testing code that calls a constructor? For example: public class ClassToTest { public void MethodToTest() { MyObject foo = new MyObject(); Console.WriteLine(foo.ToString()); } } In this example, I need to create a unit test that confirms that calling MethodToTest on an instance of ClassToTest will indeed output whatever the result of the ToString() method of a newly created instance of MyObject. I can't see a way of realistically testing the 'ClassToTest' class in isolation; testing this method would actually test the 'myObject.ToString()' method as well as the MethodToTest method.

  • Get a string sequence from a node-set in xpath 1.0

    - by Miguel
    I'm using xpath 1.0 to parse an html file and I want to get a string sequence from a node-set. First I select a node-set (eg: //div) and then I want the string-value of each node of the set. I've tried with string(//div) but it only returns the string-value of the first node in the set. Example <foo> <div> bbbb<p>aaa</p> </div> <div> cccc<p>aaa</p> </div> </foo> I expect a result like ('bbbbaaa', 'ccccaaa') but I only get 'bbbaaa'

  • Problem configuring application specific loggin glassfish v3

    - by Shane
    I am using java.util.logging in an EJB application running on glassfish v3. I can see the log messages in server.log but i don't seem to be able to configure the logging level in glassfish\domains\domain1\logging.properties. If I use: Logger logger = Logger.getLogger("com.foo"); To obtain the logger and log with: logger.info("message"); then I expect that if I set com.foo.level=WARNING in logging.properties then the message should not logged. Am I doing something wrong here?

  • LuaInterface - how to register overloaded methods?

    - by JeffreySadeli
    Hello world! I'm trying to integrate Lua to my C# app when I hit a little snag. I was hoping someone with more expertise could help point me to the right direction. Let's say I have the following C# methods: public void MyMethod(int foo) { ... } public void MyMethod(int foo, int bar) { ... } I would like to register it to my Lua script environment so that I can do something like this: -- call method with one param MyMethod(123) -- call method with two params MyMethod(123, 456) I tried RegisterFunction("MyMethod", this, this.GetType().GetMethod("MyMethod")) but it reasonably complains about ambiguous match. Any ideas?

  • How to set the value of a wx.combobox by posting an event

    - by Adam Fraser
    The code below demonstrates the problem I am running into. I am creating a wx.ComboBox and trying to mimic it's functionality for testing purposes by posting a wxEVT_COMMAND_COMBOBOX_SELECTED event... this event strangely works fine for wx.Choice, but it doesn't do anything to the ComboBox. There doesn't appear to be a different event that I can post to the combobox, but maybe I'm missing something. I'm running this code on Python 2.5 on a Mac OSX 10.5.8 import wx app = wx.PySimpleApp() def on_btn(evt): event = wx.CommandEvent(wx.wxEVT_COMMAND_COMBOBOX_SELECTED,combobox.Id) event.SetEventObject(combobox) event.SetInt(1) event.SetString('bar') combobox.Command(event) app.ProcessPendingEvents() frame = wx.Frame(None) panel = wx.Panel(frame, -1) # This doesn't work combobox = wx.ComboBox(panel, -1, choices=['foo','bar']) # This works #combobox = wx.Choice(panel, -1, choices=['foo','bar']) combobox.SetSelection(0) btn = wx.Button(panel, -1, 'asdf') btn.Bind(wx.EVT_BUTTON, on_btn) sz = wx.BoxSizer() sz.Add(combobox) sz.Add(btn) panel.SetSizer(sz) frame.Show() app.MainLoop()

  • Trouble assigning a tr1::shared_ptr

    - by Max
    I've got a class that has a tr1::shared_ptr as a member, like so: class Foo { std::tr1::shared_ptr<TCODBsp> bsp; void Bar(); } In member function Bar, I try to assign it like this: bsp = newTCODBsp(x,y,w,h); g++ then gives me this error no match for ‘operator=’ in ‘((yarl::mapGen::MapGenerator*)this)->yarl::mapGen::MapGenerator::bsp = (operator new(40u), (<statement>, ((TCODBsp*)<anonymous>)))’ /usr/include/c++/4.4/tr1/shared_ptr.h:834: note: candidates are: std::tr1::shared_ptr<TCODBsp>& std::tr1::shared_ptr<TCODBsp>::operator=(const std::tr1::shared_ptr<TCODBsp>&) in my code, Foo is actually yarl::mapGen::MapGenerator. What am I doing wrong?

  • .NET 2.0: Invoking Methods Using Reflection And Generics Causes Exception

    - by David Derringer
    Hi all, I'm new to Stack Overflow, so forgive me. I've just started transititoning over to C# and I am stuck on a problem. I am wanting to pass a generic class in and call a method from that class. So, my code looks as such: public void UpdateRecords<T>(T sender) where T : new() //where T: new() came from Resharper { Type foo = Type.GetType(sender.GetType().ToString()); object[] userParameters = new object[2]; userParameters[0] = x; userParameters[1] = y; sender = new T(); //This was to see if I could solve my exception problem MethodInfo populateRecord = foo.GetMethod("MethodInOtherClass"); populateMethod.Invoke(sender, userParameters); } Exception thrown: "Object reference not set to an instance of an object." Again, I really apologize, as I am nearly brand new to C# and this is the first time I've ever handled reflection and generics. Thank you!

  • Simple string parsing with C++

    - by Andreas Brinck
    I've been using C++ for quite a long time now but nevertheless I tend to fall back on scanf when I have to parse simple text files. For example given a config like this (also assuming that the order of the fields could vary): foo: [3 4 5] baz: 3.0 I would write something like: char line[SOME_SIZE]; while (fgets(line, SOME_SIZE, file)) { int x, y, z; if (3 == sscanf(line, "foo: [%d %d %d]", &x, &y, &z)) { continue; } float w; if (1 == sscanf(line, "baz: %f", &w)) { continue; } } What's the most concise way to achieve this in C++? Whenever I try I end up with a lot of scaffolding code.

  • Better method for flipping multidimensional array?

    - by sudowned
    I've retrieved some data from the database, which is in the following structure: [0] [item_id] = 197 [dice_chat_css] = "foo" [dice_image] = "bar.png" [1] [item_id] = 128 [dice_chat_css] = "foo" [dice_image] = "bar.png" The most convenient and computationally inexpensive way for me to pass this data to the rest of my (PHP) application is with item_id as the index, because it saves having to loop over the array to look up values. If this was a flat array, I could accomplish this trivially with array_flip, but since it isn't, it's my pick of using either the multidimensional array_flip listed in the comments on PHP.net, or roll my own logic: for ($i = 0; $i < sizeOf($r); $i++){ $s[$r[$i]['item_id']]['dice_image'] = $r[$i]['dice_image']; $s[$r[$i]['item_id']]['dice_chat_css'] = $r[$i]['dice_chat_css']; } I know it's simple, but it feels like I'm reinventing the wheel here. Is there an accepted, more optimized method available or am I being weird about this?

  • Forward web request for directory index ('/') to an index.htm page in JBoss 4.0.5

    - by The Pretender
    I am using JBoss 4.0.5.GA to run a set of java applications. One of them is a web frontend, using Spring 1.4. URL mappings are configured in a way that 'fake' pages from request URLs are mapped to controllers. That means that when someone requests /index.htm, there's no actual 'index.htm' on disk, and that request maps to a specific conroller which then renders a jsp view. So the problem is as follows: I need to tell JBoss to somehow forward all requests for directory indices to corresponding 'index.htm' URLs like so: / ? /index.htm; /news/ ? /news/index.htm; /foo/bar/baz/ ? /foo/bar/baz/index.htm and so on. I can't use Tomcat's welcome-file-list feature because it looks for those files on disk, while all 'index.htm's are fake and don't actually exist on disk.

  • How can a running application in Linux/*nix determine its own absolute path?

    - by Dave Wade-Stein
    Suppose you run the application 'app' by typing 'app', rather than its absolute path. Due to your $PATH variable, what actually runs is /foo/bar/app. From inside app I'd like to determine /foo/bar/app. argv[0] is just 'app', so that doesn't help. I know in Linux I can get do pid = getpid(); and then look at the /proc/pid/exe softlink, but that doesn't work on other *nix. Is there a more portable way to determine the dir in which the app lives?

  • Use 'let' in 'if' expression

    - by demas
    I need a function that works like this: foo :: Integer -> Integer -> [Integer] foo a b = do let result = [] let Coord x y = boo a b if x > 0 let result = result ++ [3] if y > 0 let result = result ++ [5] if x < a let result = result ++ [7] if y < b let result = result ++ [9] result I can not use the guards because the result can have more then one element. But as I see I can not use 'let' in the 'if' expression: all_possible_combinations.hs:41:14: parse error on input `let' How can I check multiple expressions and add new elements in the list? I search not only imperative solution, but the functional one.

  • ASP.NET MVC View Not posting back to Post method and expecting a parameterless Constructor?

    - by VJ
    Hi, I am trying to post back some data using a viewmodel i have created and it works for me for one of the projects.But I am doin this right now public ActionResult Foo(string userkey) { vm.Value="Xvalue"; return View(vm); } [HttpPost] public ActionResult Foo( MyViewModel vm) { // process input if (inputOK) string value=vm.Value return RedirectToAction("Index"); return View(); } public class MyViewModel { public string Value { get; set; } public SomeClass newobj {get;set;} } public class SomeClass { public int id{get;set;} public string str{get;set;} } So it on debugging never goes into the parameter method for Post although on the view i have added a form and a button that submits and the page inherits from the viewmodel.I get an error saying it expects a parameterless constructor how do I fix this ? . I wrote an post method with no parameters and it does go into that method

  • How do I change the style of an input box in IE7 on focus?

    - by Cen
    I know IE7 has issues... I've read posts here and on Google telling me I need to set the style by hand onfocus() and onblur(). However, everything I try isn't working! Here is my jQuery $(document).ready(function(){ if (jQuery.browser.msie === true) { $("input.date-picker").each(function(i) { var $foo= $(this); $foo.bind('onfocus onblur', function() { $(this).toggleClass('smalltxt-active'); }); }); }//end if }); The a corresponding box <input name="ctl00$SelectionContent$Selections1$txtDestinationDate" type="text" id="ctl00_SelectionContent_Selections1_txtDestinationDate" class="date-picker" style="width:80px;" /> I have already confirmed that my code is detecting MSIE. That I am getting a count of 2 input.date-picker objects. Any ideas? Thanks in advance,

  • Is there an additional runtime cost for using named parameters?

    Consider the following struct: public struct vip { string email; string name; int category; public vip(string email, int category, string name = "") { this.email = email; this.name = name; this.category = category; } } Is there a performance difference between the following two calls? var e = new vip(email: "foo", name: "bar", category: 32); var e = new vip("foo", 32, "bar"); Is there a difference if there are no optional parameters defined?

  • How to expose a constructor variable(sic!) as read-only?

    - by Malax
    Hi StackOverflow! I have this rather simple question about Scala. Given that i have to following class definition: class Foo(var bar: Int) The code which is able to construct an instance of Foo must be able to pass the initial value for bar. But if I define bar as var the User is also able to change its value at runtime which is not what I want. The User should only be able to read bar. bar itself is modified internally so a val is not an option. I think I might be getting an answer very soon as this question is so simple. :-) Cheers, Malax

  • Starting mongrel with a custom command line argument

    - by whaka
    I would like to be able to start a mongrel or webrick server by passing an extra command line argument that I can read somewhere inside my rails application. An example would be: ruby script/server -p3000 --target=FOO Here, --target is a custom switch who's value I would like to intercept in my rails application. However, this yields the error: server: invalid option: --target=FOO I found mongrel documentation which mentions a -C (--config=PATH) argument specifying a full path to a yml configuration file, but specifying that switch gives the same error as above. I presume this option is deprecated. Is there another way to accomplish this?
