  • Why isn't the scripts in my autoload folder being executed in Vim?

    - by Codemonkey
    I'm trying to use Pathogen to manage my Vim extensions. My bundle folder looks like this: .../bundle/ +-- vim-pathogen ¦   +-- autoload ¦   +-- pathogen.vim +-- vim-smoothscroll +-- autoload +-- smooth_scroll.vim And my vimrc file includes this: let s:root = fnamemodify(resolve(expand(":p")), ":h") " Initiate pathogen. exec "source " . s:root . "/vimfiles/bundle/vim-pathogen/autoload/pathogen.vim" exec pathogen#infect() My vimrc file is a symlink located in ~ but pointing to a folder inside my Dropbox folder. This appears to work when I start Vim. Pathogen has added vim-smoothscroll to my runtimepath: :set runtimepath? runtimepath=~/Dropbox/Personal/config_sync/vim/vimfiles,~/Dropbox/Personal/config_sync/vim/vimfiles/bundle/vim-p athogen,~/Dropbox/Personal/config_sync/vim/vimfiles/bundle/vim-smoothscroll,~/.vim,~/vim/share/vim/vimfiles,~/vim/ share/vim/vim74,~/vim/share/vim/vimfiles/after,~/.vim/after The problem is that the script smooth_scroll.vim hasn't been loaded: 1: ~/.vimrc 2: ~/Dropbox/Personal/config_sync/vim/vimfiles/bundle/vim-pathogen/autoload/pathogen.vim 3: ~/vim/share/vim/vim74/syntax/syntax.vim 4: ~/vim/share/vim/vim74/syntax/synload.vim 5: ~/vim/share/vim/vim74/syntax/syncolor.vim 6: ~/vim/share/vim/vim74/filetype.vim 7: ~/vim/share/vim/vim74/menu.vim 8: ~/vim/share/vim/vim74/autoload/paste.vim 9: ~/Dropbox/Personal/config_sync/vim/vimfiles/colors/codeschool.vim 10: ~/Dropbox/Personal/config_sync/vim/_vimrc_gui 11: ~/Dropbox/Personal/config_sync/vim/_vimrc_keybinds 12: ~/vim/share/vim/vim74/plugin/getscriptPlugin.vim 13: ~/vim/share/vim/vim74/plugin/gzip.vim 14: ~/vim/share/vim/vim74/plugin/matchparen.vim 15: ~/vim/share/vim/vim74/plugin/netrwPlugin.vim 16: ~/vim/share/vim/vim74/plugin/rrhelper.vim 17: ~/vim/share/vim/vim74/plugin/spellfile.vim 18: ~/vim/share/vim/vim74/plugin/tarPlugin.vim 19: ~/vim/share/vim/vim74/plugin/tohtml.vim 20: ~/vim/share/vim/vim74/plugin/vimballPlugin.vim 21: ~/vim/share/vim/vim74/plugin/zipPlugin.vim 22: ~/vim/share/vim/vim74/syntax/ruby.vim 23: ~/vim/share/vim/vim74/syntax/vim.vim 24: ~/vim/share/vim/vim74/syntax/python.vim Why is that?

  • Behavior Driven Development (BDD) and DevExpress XAF

    - by Patrick Liekhus
    So in my previous posts I showed you how I used EDMX to quickly build my business objects within XPO and XAF.  But how do you test whether your business objects are actually doing what you want and verify that your business logic is correct?  Well I was reading my monthly MSDN magazine last last year and came across an article about using SpecFlow and WatiN to build BDD tests.  So why not use these same techniques to write SpecFlow style scripts and have them generate EasyTest scripts for use with XAF.  Let me outline and show a few things below.  I plan on releasing this code in a short while, I just wanted to preview what I was thinking. Before we begin… First, if you have not read the article in MSDN, here is the link to the article that I found my inspiration.  It covers the overview of BDD vs. TDD, how to write some of the SpecFlow syntax and how use the “Steps” logic to create your own tests. Second, if you have not heard of EasyTest from DevExpress I strongly recommend you review it here.  It basically takes the power of XAF and the beauty of your application and allows you to create text based files to execute automated commands within your application. Why would we do this?  Because as you will see below, the cucumber syntax is easier for business analysts to interpret and digest the business rules from.  You can find most of the information you will need on Cucumber syntax within The Secret Ninja Cucumber Scrolls located here.  The basics of the syntax are that Given X When Y Then Z.  For example, Given I am at the login screen When I enter my login credentials Then I expect to see the home screen.  Pretty easy syntax to follow. Finally, we will need to download and install SpecFlow.  You can find it on their website here.  Once you have this installed then let’s write our first test. Let’s get started… So where to start.  Create a new testing project within your solution.  I typically call this with a similar naming convention as used by XAF, my project name .FunctionalTests (i.e.  AlbumManager.FunctionalTests).  Remove the basic test that is created for you.  We will not use the default test but rather create our own SpecFlow “Feature” files.  Add a new item to your project and select the SpecFlow Feature file under C#.  Name your feature file as you do your class files after the test they are performing. Now you can crack open your new feature file and write the actual test.  Make sure to have your Ninja Scrolls from above as it provides valuable resources on how to write your test syntax.  In this test below you can see how I defined the documentation in the Feature section.  This is strictly for our purposes of readability and do not effect the test.  The next section is the Scenario Outline which is considered a test template.  You can see the brackets <> around the fields that will be filled in for each test.  So in the example below you can see that Given I am starting a new test and the application is open.  This means I want a new EasyTest file and the windows application generated by XAF is open.  Next When I am at the Albums screen tells XAF to navigate to the Albums list view.  And I click the New:Album button, tells XAF to click the new button on the list grid.  And I enter the following information tells XAF which fields to complete with the mapped values.  And I click the Save and Close button causes the record to be saved and the detail form to be closed.  Then I verify results tests the input data against what is visible in the grid to ensure that your record was created. The Scenarios section gives each test a unique name and then fills in the values for each test.  This way you can use the same test to make multiple passes with different data. Almost there.  Now we must save the feature file and the BDD tests will be written using standard unit test syntax.  This is all handled for you by SpecFlow so just save the file.  What you will see in your Test List Editor is a unit test for each of the above scenarios you just built. You can now use standard unit testing frameworks to execute the test as you desire.  As you would expect then, these BDD SpecFlow tests can be automated into your build process to ensure that your business requirements are satisfied each and every time. How does it work? What we have done is to intercept the testing logic at runtime to interpret the SpecFlow syntax into EasyTest syntax.  This is the basic StepDefinitions that we are working on now.  We expect to put these on CodePlex within the next few days.  You can always override and make your own rules as you see fit for your project.  Follow the MSDN magazine above to start your own.  You can see part of our implementation below. As you can gather from the MSDN article and the code sample below, we have created our own common rules to build the above syntax. The code implementation for these rules basically saves your information from the feature file into an EasyTest file format.  It then executes the EasyTest file and parses the XML results of the test.  If the test succeeds the test is passed.  If the test fails, the EasyTest failure message is logged and the screen shot (as captured by EasyTest) is saved for your review. Again we are working on getting this code ready for mass consumption, but at this time it is not ready.  We will post another message when it is ready with all details about usage and setup. Thanks

  • Debugging matchit plugin in vim (under Cygwin)

    - by system PAUSE
    The "matchit" plugin for vim is supposed to allow you to use the % key to jump between matching start/end tags when editing HTML, as well as /* and */ comment delimiters when editing other kinds of code. I've followed the exact instructions in ":help matchit", but % still doesn't work for me. It seems silly to ask "Why doesn't this work?" so instead I'm asking How can I diagnose the problem? Pointers to references are welcome, but specific vim-plugin-debugging techniques are preferred. Here is the ~/.vim directory: $ ls -ltaGR ~/.vim /cygdrive/y/.vim: total 0 drwxr-xr-x 1 spause 0 Sep 17 13:20 .. drwxr-xr-x 1 spause 0 Sep 16 13:59 doc drwxr-xr-x 1 spause 0 Sep 16 13:58 . drwxr-xr-x 1 spause 0 Sep 16 13:58 plugin /cygdrive/y/.vim/doc: total 24 -rw-r--r-- 1 spause 1961 Sep 16 13:59 tags drwxr-xr-x 1 spause 0 Sep 16 13:59 . -rw-r--r-- 1 spause 19303 Sep 16 13:58 matchit.txt drwxr-xr-x 1 spause 0 Sep 16 13:58 .. /cygdrive/y/.vim/plugin: total 32 drwxr-xr-x 1 spause 0 Sep 16 13:58 .. -rw-r--r-- 1 spause 30714 Sep 16 13:58 matchit.vim drwxr-xr-x 1 spause 0 Sep 16 13:58 .

  • How to add Compass syntax support to Jetbrains PhpStorm?

    - by Madara Uchiha
    I'm using JetBrains PhpStorm, which is probably the most epic IDE I've ever used. The question is simple. How do I add Compass syntax support to it? I've got it installed, it renders and works, but PhpStorm still complains about undefined imports and mixins. How can I resolve this? Can Compass be included as an external library? Edit: I'd just like to note that this feature request is for the RubyMine IDE (also by JetBrains), it's not for PhpStorm/WebStorm.

  • Parse error: syntax error, unexpected T_PUBLIC in ..... ?

    - by tonsils
    Hi, I am new to php and trying out this tutorial at : http://css-tricks.com/php-for-beginners-building-your-first-simple-cms/ Unfortunately I am getting the following error and can't seem to track down the reason: Parse error: syntax error, unexpected T_PUBLIC in ../simpleCMS.php on line 56 My code for simpleCMS.php is as is in the tutorial link above. FYI, my line 56 is the following line of code in simpleCMS.php public function display_admin() { Above this line is public function display_public() Can anyone possibly see what I could be doing wrong and again, my code is the same code from the tutorial website and have downloaded the files that came with it? Hoping someone can point me in the right direction. Furthermore, I am using Mac OS X MAMP to run my Apache/MySQL Server locally. My other question is, when I using the following command: mysql_connect($this->host,$this->username,$this->password) is my hostname 'localhost' alone or do I also have to include port alongside the localhost? Thanks again.

As an example I've got the following code: Where does the object "status.menueStatus" have to be defined in order to can be accessed with a dollar sign and braces. Is it defined in another struts tile or in the form? Whether within our project code nor by Google I can get any help. Your support would be very appreciated. Thank you. Bernhard

  • DirectX 9 HLSL vs. DirectX 10 HLSL: syntax the same?

    - by numerical25
    For the past month or so, I have been busting my behind trying to learn DirectX. So I've been mixing back back and forth between DirectX 9 and 10. One of the major changes I've seen in the two is how to process vectors in the graphics card. One of the drastic changes I notice is how you get the GPU to recognize your structs. In DirectX 9, you define the Flexible Vertex Formats. Your typical set up would be like this: #define CUSTOMFVF (D3DFVF_XYZRHW | D3DFVF_DIFFUSE) In DirectX 10, I believe the equivalent is the input vertex description: D3D10_INPUT_ELEMENT_DESC layout[] = { {"POSITION",0,DXGI_FORMAT_R32G32B32_FLOAT, 0 , 0, D3D10_INPUT_PER_VERTEX_DATA, 0}, {"COLOR",0,DXGI_FORMAT_R32G32B32A32_FLOAT, 0 , 12, D3D10_INPUT_PER_VERTEX_DATA, 0} }; I notice in DirectX 10 that it is more descriptive. Besides this, what are some of the drastic changes made, and is the HLSL syntax the same for both?

  • Syntax error converting the nvarchar value to a column of data type int.

    - by Phil
    I have 1,2,3,4,5,6,7,8,9 stored as nvarchar inside Level in my db. I then have a dropdownlist with values 1,2,3,4,5,6,7,8,9. When a user makes a selection (i.e 1) (Level.SelectedValue.ToString). This builds an sql query via a param like this: "Select things From MBA_EOI Where level = 1" When I run the select I get the following error: Syntax error converting the nvarchar value '1,2,3,4,5,6,7,8,9' to a column of data type int. I was under the impression that I was dealing with an Nvarchar field and the selected value as string, where does the int conversion come in? p.s I have also tried Level.SelectedItem.ToString

  • Are Scala "continuations" just a funky syntax for defining and using Callback Functions?

    - by Alex R
    And I mean that in the same sense that a C/Java for is just a funky syntax for a while loop. I still remember when first learning about the for loop in C, the mental effort that had to go into understanding the execution sequence of the three control expressions relative to the loop statement. Seems to me the same sort of effort has to be applied to understand Continuations (in Scala and I guess probably other languages). And then there's the obvious follow-up question... if so, then what's the point? It seems like a lot of pain (language complexity, programmer errors, unreadable programs, etc) for no gain.

  • Why does concatenating strings in the argument of EXEC sometimes cause a syntax error in T-SQL?

    - by Tim Goodman
    In MS SQL Server Management Studio 2005, running this code EXEC('SELECT * FROM employees WHERE employeeID = ' + CAST(3 AS VARCHAR)) gives this error: Incorrect syntax near 'CAST' However, if I do this, it works: DECLARE @temp VARCHAR(4000) SET @temp = 'SELECT * FROM employees WHERE employeeID = ' + CAST(3 AS VARCHAR) EXEC(@temp) I found an explanation here: http://stackoverflow.com/questions/1044831/t-sql-cannot-pass-concatenated-string-as-argument-to-stored-procedure According to the accepted answer, EXEC can take a local variable or a value as its argument, but not an expression. However, if that's the case, why does this work: DECLARE @temp VARCHAR(4000) SET @temp = CAST(3 AS VARCHAR) EXEC('SELECT * FROM employees WHERE employeeID = ' + @temp) 'SELECT * FROM employees WHERE employeeID = ' + @temp sure looks like an expression to me, but the code executes with no errors.

  • Doesn’t <asp:A runat=”server” B=”someValue” … /> syntax violate one of the basic rules in C# languag

    - by AspOnMyNet
    Assuming server control of type A has a protected member M, then we are also able to access A.M via declaring control tag A on some aspx page: <asp:A runat=”server” M=”someValue” … /> But isn’t one of the rules in C# that protected members of class A can only be accessed from A and from classes derived from A? So doesn’t the ability to access member A.M via <asp:A M=”someValue” … /> syntax violate this rule, since we are basically accessing A.M from a class ( which is automatically generated aspx class ) not derived from A?!

  • How to learn programming language (syntax rules, etc.) and remember easily? [closed]

    - by user239522
    I'm new to programming, and I always have a so call difficulty, that is, I always tend to forget the thing (syntax, rules, name, definition or anyting) of a programming language I've learnt. And I personally do feel that the way I learn it is wrong. Here is my method. Everyday I will spend approximately 1 or 2 hours on a programming e-book. I just follow the syllabus and teaching inside the books, of course I have try to code myself, alter the code inside the book, and did the exercises available. But everytime right after I finish a chapter and advanced myself to third or fourth chapter, I will forgot something I learnt in the first chapter. Is it the method I use wrong? Does learning through reading and coding not enough? Do I need to everytime make a small note (mind map for example) of things I've learnt by hand writing? Or do I sometime need to try coding using a pencil and a book, but not a computer?

  • What is the most concise, unambiguous syntax for operator associated methods (for overloading etc.) that doesn't pollute the namespace?

    - by Doug Treadwell
    Python tends to add double underscores before its built-in or overloadable operator methods, like __add(), whereas C++ requires declaring overloaded operators as operator + (Thing& thing) { /* code */ } for example. Personally I like the operator syntax because it seems to be more explicit and keeps these operator overloading methods separated from other methods without introducing weird prefix notation. What are your thoughts? Also, what about the case of built-in methods that are needed for the programming language to work properly? Is name mangling (like adding __ prefix or sys or something) the best solution here? What do you think about having another type of method declaration, like ... "system method" for lack of creativity at the moment. So there would be two kinds of declarations: int method_name() { ... } system int method_name() { ... } ... and the call would need to be different to distinguish between them. obj.method_name(); vs obj:method_name(); perhaps, assuming a language where : can be unambiguously used in this situation. obj.method_name() vs obj.(system method_name)() Sure, the latter is ugly, but the idea is to make the common case simple and system stuff should be kept out of the way. Maybe the Objective-C notation of method calls? [obj method_name]? Are there more alternatives? Please make suggestions.

    ok I have couple of .NET classes that I want to use in VBA. So I must register them through COM and all that. I think I have the COM registration figured out (finally) but now I need help with the syntax of how to create the objects. Here is some pseudo code showing what I am trying to do. EDIT: Changed Attached Objects to return an ArrayList instead of a List The .NET classes look like this... public class ResourceManagment { public ResourceManagment() { // Default Constructor } public static List<RandomObject> AttachedObjects() { ArrayList list = new ArrayList(); return list; } } public class RandomObject { // public RandomObject(int someParam) { } } OK, so this is what I would like to do in VBA (demonstrated in C#) but I don't know how... public class VBAClass { public void main() { ArrayList myList = ResourceManagment.AttachedObjects(); foreach(RandomObject x in myList) { // Do something with RandomObject x like list them in a Combobox } } } One thing to note is that RandomObject does not have a public default constructor. So I can not create an instance of it like Dim x As New RandomObject. MSDN says that you can not instantiate an object that doesn't have a default constructor through COM but you can still use the object type if it is returned by another method... Types must have a public default constructor to be instantiated through COM. Managed, public types are visible to COM. However, without a public default constructor (a constructor without arguments), COM clients cannot create an instance of the type. COM clients can still use the type if the type is instantiated in another way and the instance is returned to the COM client. You may include overloaded constructors that accept varying arguments for these types. However, constructors that accept arguments may only be called from managed (.NET) code. Added: Here is my attempt in VB: Dim count As Integer count = 0 Dim myObj As New ResourceManagment For Each RandomObject In myObj.AttachedObjects count = count + 1 Next RandomObject

  • What is the correct syntax for XSD to restrict attrributes values in the elements list?

    - by Leonard
    What is the correct syntax for XSD schema to define the following restriction: In the list of elements we have to specify that attribute can contain value of "c" unlimited number of times, but value of "b" - the zero or only one time. For example, the correct xml looks like this: <root> <elem atr="c">111</elem> <elem atr="c">222</elem> <elem atr="b">333</elem> <elem atr="c">444</elem> <elem atr="c">555</elem> </root> And incorrect one is: <root> <elem atr="c">111</elem> <elem atr="c">222</elem> <elem atr="b">333</elem> <elem atr="c">444</elem> <elem atr="b">555</elem> </root>
