  • zsh for loop exclusion

    - by ABach
    This is somewhat of a simple question, but for the life of me, I cannot figure out how to exclude something from a zsh for loop. For instance, let's say we have this: for $package in /home/user/settings/* do # do stuff done Let's say that in /home/user/settings/, there is a particular directory ("os") that I want to ignore. Logically, I tried the following variations: for $package in /home/user/settings/^os (works w/ "ls", but not with a foor loop) for $package in /home/user/settings/*^os for $package in /home/user/settings/^os* ...but none of those seem to work. Could someone steer my syntax in the right direction?

  • SASS color array

    - by Eric Holmes
    I am trying to write a loop that will cycle through colors and condense the amount of code in my scss file. Here is a simple example of what I have: $color1: blue; $color2: red; $color3: white; $color4: black; .color1-bg { background-color: $color1; } .color2-bg { background-color: $color2; } .color1-border { border-color: $color1; } .color2-border { border-color: $color2; } And so on. I am looking for a way to make the equivalent of a foreach loop, and cycle through an 'array' of colours by index. Something like this: @each $color in $color1, $color2, $color3, $color4 { .{$color}-bg { background-color: $color; .{$color}-border { border-color: $color; } I know the syntax is wrong, but that is my thinking process. Thanks for the help!

  • fgets, sscanf, and writing to arrays

    - by alldavidsluck
    beginner question here, I haven't been able to find examples that relate. I'm working on a C program that will take integer input from stdin using fgets and sscanf, and then write it to an array. However, I'm not sure how to make fgets write to the array. #define MAXINT 512 char input[MAXINT] int main(void) { int i; int j; int count=0; int retval; while (1==1) { fgets(input, MAXINT[count], stdin); retval = sscanf(input, "%d", &i); if (retval == 1) { count = count++; } else if (retval != 1) { break; } } Would I simply put fgets in a for loop? or is it more complicated than that?

  • Regular expressions in python unicode

    - by Remy
    I need to remove all the html tags from a given webpage data. I tried this using regular expressions: import urllib2 import re page = urllib2.urlopen("http://www.frugalrules.com") from bs4 import BeautifulSoup, NavigableString, Comment soup = BeautifulSoup(page) link = soup.find('link', type='application/rss+xml') print link['href'] rss = urllib2.urlopen(link['href']).read() souprss = BeautifulSoup(rss) description_tag = souprss.find_all('description') content_tag = souprss.find_all('content:encoded') print re.sub('<[^>]*>', '', content_tag) But the syntax of the re.sub is: re.sub(pattern, repl, string, count=0) So, I modified the code as (instead of the print statement above): for row in content_tag: print re.sub(ur"<[^>]*>",'',row,re.UNICODE But it gives the following error: Traceback (most recent call last): File "C:\beautifulsoup4-4.3.2\collocation.py", line 20, in <module> print re.sub(ur"<[^>]*>",'',row,re.UNICODE) File "C:\Python27\lib\re.py", line 151, in sub return _compile(pattern, flags).sub(repl, string, count) TypeError: expected string or buffer What am I doing wrong?

  • Log information inside a JUnit Suite

    - by Alex Marinescu
    I'm currently trying to write inside a log file the total number of failed tests from a JUnite Suite. My testsuite is defined as follows: @RunWith(Suite.class) @SuiteClasses({Class1.class, Class2.class etc.}) public class SimpleTestSuite {} I tried to define a rule which would increase the total number of errors when a test fails, but apparently my rule is never called. @Rule public MethodRule logWatchRule = new TestWatchman() { public void failed(Throwable e, FrameworkMethod method) { errors += 1; } public void succeeded(FrameworkMethod method) { } }; Any ideas on what I should to do to achieve this behaviour?

  • MS SQL Server 2008 Stored Procedure Result as Column Default Value

    - by user337501
    First of all, thank you guys. You always know how to direct me when I cant even find the words to explain what the heck im trying to do. The default values of the columns on a couple of my tables need to equal the result of some complicated calculations on other columns in other tables. My first thought is to simply have the column default value equal the result of a stored procedure. I would also have one or more of the parameters pulled from the columns in the calling table. I don't know the syntax of how to do it though, and any time the word "stored" and "procedure" land next to each other in google I'm flooded with info on Parameter default values and nothing relating to what I actually want. Half of that was more of a vent than a question...any ideas though? And plz plz dont say "Well, you could use an On-Insert Trigger to..."

  • JavaScript Namespace Declaration

    - by Hery
    I created a javascript class as follow: var MyClass = (function() { function myprivate(param) { console.log(param); } return { MyPublic : function(param) { myprivate(param); } }; })(); MyClass.MyPublic("hello"); The code above is working, but my question is, how if I want to introduce namespace to that class. Basically I want to be able to call the class like this: Namespace.MyClass.MyPublic("Hello World"); If I added Namespace.MyClass, it'll throw error "Syntax Error". I did try to add "window.Namespace = {}" and it doesn't work either. Thanks.. :)

  • Sending mail using CDO JavaScript error - Server is undefined

    - by Rotem
    Hi, I got this code to send email using SMTP server, I tried many configuration of it that I found online, also VBscript similar code, and non of it is working. I want to focus on this code, when I'm opening the HTA I'm getting error in line 8, says 'Server is undefined', What should I do to define it? var cdoConfig = Server.CreateObject("CDO.Configuration"); cdoConfig.Fields("cdoSMTPServerName") = "194.90.9.22"; var cdoMessage = Server.CreateObject("CDO.Message"); cdoMessage.Configuration = cdoConfig; var cdoBodyPart = cdoMessage.BodyPart; cdoMessage.To = "[email protected]"; cdoMessage.From = "[email protected]"; cdoMessage.Subject = "CDO Test in JScript"; cdoMessage.TextBody = "This is a test email sent using JScript."; cdoMessage.send(); Thanks, Rotem

  • How can I programmically construct the object reference?

    - by Bryan
    Lets just say that I have three textboxes: TextBox1, TextBox2, TextBox3. Normally if I wanted to change the text for example I would put TextBox1.Text = "Whatever" and so on. For what I'm doing right now I would like to something like (TextBox & "i").Text. That obviously isn't the syntax I need to use I'm just using it as an example for what I need to do. So how can I do something like this? The main reason I'm doing this is to reduce code with a loop. Please keep in mind that I'm not actually changing the text of the textboxes I'm simply using that as an example to get the point across.

  • Property value of a String object in JavaScript

    - by naivists
    As far as I understand, every string is an object in Javascript. Still, it "does not work" as I expect it to be: var a="abc"; //here we get a new string object a.b = 123; //I seem to declare a property "b" of that object alert(a.b); //alerts "undefined" However, if I try to define a string in the "wrong way", everything works as expected var a=new String("abc"); // a.b = 123; alert(a.b); //alerts "123" Why is that so?

  • php database session handling problem in IE8!

    - by psyb0rg
    I've got an html page from where Im making this call periodically: function logon(id) { $.get("data.php", { action: 'online', userID: id}, function(data){ $("#msg").html(data); }); } What this does is it calls this SQL script in data.php: $sql = "update user_sessions set expires=(expires + 2) where userID = $userID"; mysql_query($sql, $conn) or die(mysql_error()); echo $sql; I can see by the echo that the sql syntax and values are correct, but THE CHANGES TO THE expires FIELD ARE NOT DONE, ONLY IN IE8!! It works fine in other ff, safari, chrome, ie6 and 7. There is nothing browser specific about making this sql call, but the user_sessions table is used to store PHP's sessions. Im only increasing the session expiry time when the call is made. What in IE8's session handling is preventing the session time from changing? Is there any caching or cookie problem that needs to be changed?

  • design pattern tools to use?

    - by ajsie
    i have noticed that every area has some tools you can use to make things easier. eg. css = dreamweaver doctrine/propel = orm designer // you dont have to hardcore code schemas manually and remembering all the syntax/variables mysql = mysql workbench // the same etc. in this way you get aided and dont have to type things the hard way, and can learn the structure, but then use GUI tools to help you develop faster. now i'm learning design patterns (singleton, factory, command, memento etc) and im wondering if there are some kind of tools you can use that will help you develop faster. i dont know exactly what tools i'm trying to find, just helping me when coding with design patterns (schema drawings? references?) are there any?

  • Best approch to dynamically filter .net objects

    - by maxba
    The project i´m working currently on has a way to define a filter to filter objects from a database. This filter is a pretty straitforward class containing filtercriteria that will be combined to a sql where-clause. The goal now is to use this filter class to filter .net objects as well. So the filter for example defines, that the title property of the object that it is applied to must contain some userdefined string etc. What are ways to approch this problem? What should the filter return instead of the sql where-clause and how can it be applied to the object? I´m thinking about this for hours and don´t yet have even a slight idea how to solve this. Been thinking about reflection, dynamic code execution, building expressions but still haven´t found an acutal starting point.

  • Why can't I find DataTemplates in merged resource dictionaries?

    - by dthrasher
    In my MainWindow.xaml, I have the following reference to a ResourceDictionary: <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="MainSkin.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Window.Resources> In MainSkin.xaml, I define a datatemplate: <DataTemplate x:Key="TagTemplate"> ... </DataTemplate> Deeper within my application, I attempt to use this data template: <ContentControl DataContext="{Binding Tag}" ContentTemplate="{StaticResource TagTemplate}"/> The code compiles successfully, but when I attempt to load a Page or UserControl that contains this StaticResource, I get an exception saying that the TagTemplate can't be found. What am I doing wrong?

  • Operator Overloading with C# Extension Methods

    - by Blinky
    I'm attempting to use extension methods to add an operater overload to the C# StringBuilder class. Specifically, given StringBuilder sb, I'd like sb += "text" to become equivalent to sb.Append("text"); Here's the syntax for creating an extension method for StringBuilder: public static class sbExtensions { public static StringBuilder blah(this StringBuilder sb) { return sb; } } It successfully adds the "blah" extension method to the StringBuilder. Unfortunately, operator overloading does not seem to work: public static class sbExtensions { public static StringBuilder operator +(this StringBuilder sb, string s) { return sb.Append(s); } } Among other issues, the keyword 'this' is not allowed in this context. Are adding operator overloads via extension methods possible? If so, what's the proper way to go about it?

  • Seeking tutorial: introduction to ODBC with Delphi

    - by mawg
    I have a lot of embedded C/C++/Ada experience and an outdated smattering of Delphi plus some database stuff. Now I have to implement an app in Delphi which can manipulate MySql, Oracle, maybe MS Access. In short, I need ODBC. I need to programmatically created a database, define its structure and populate its contents, then later query its existence and programmatically search. I would prefer not to use 3rd party components, unless there is a compelling reason to do so (performance ought not to be an issue for the app, it won't have much data or be run often, at least not in v1.0) . Can anyone point me at a tutorial which can get me up to speed? Thanks

  • Spring & Hibernate EJB Events

    Is it possible to define a spring-managed EJB3 hibernate listener? I have this definition in my persistence.xml: <properties> <property name="hibernate.ejb.interceptor" value="my.class.HibernateAuditInterceptor" /> <property name="hibernate.ejb.event.post-update" value="my.class.HibernateAuditTrailEventListener" /> </properties> But I would like to manage HibernateAuditInterceptor and HibernateAuditTrailEventListener with spring, so I can do some bean injection (ex: session-scoped bean) within these classes. Is this possible?

  • How would I create a technology standards document for my company?

    - by Rob O
    I'm a Director of Product Engineering for my company. My CEO has asked me to create a technology standards document, explaining things like the technology we use, our policy on adapting to new technology, and design standards like percent of code covered by unit tests. I've never had to do something like this, and I've spent a significant amount of time searching the web for examples, but I haven't found any at all. The closest I've found are documents describing technical specifications for an individual product. However, I'm trying to define this for the entire company. Can someone provide examples of how this document could be formatted/organized, and what the typical content would be? Thanks!

  • how to load a module within python debugger

    - by MK
    This looks like something simple but I could not find the answer so far - I have just learnt python and need to start learning pdb. In my module I have the usual if __name__ == __main_ trick to execute some code when the module is run as a program. So far I have been running it via python -m mymod arg1 arg2 syntax Now I want to do exactly the same thing from inside pdb. Normally in C, I would just do gdb mybinary followed by run arg1 arg2 But I cannot figure out how to achieve the same thing in pdb. I am sure there has to be a simple way to achieve this but it is taking me too long to search for it.. Thanks for your help!

  • Create Generic Class Instance from Static Method in a Derived Class

    - by user343547
    I have a class in C# with a template and static method similar to class BClass<T> { public static BClass<T> Create() { return new BClass<T>(); } } From this I derive a class and specify a template parameter to the base class class DClass : BClass<int> { } A problem occurs when I try to use the static method to create an instance of D class Program { static void Main(string[] args) { DClass d = DClass.Create(); } } Gives a compiler error "Cannot implicitly convert type 'Test.BClass<int ' to 'Test.DClass'." Adding the below cast leads to a runtime casting exception. DClass d = (DClass)DClass.Create(); Is there any succint way to allow the static method to create instances of the derived class? Ideally I would like the equivalent of a c++ typedef and I don't want the below syntax (which does work). BClass<int> d = DClass.Create();

  • In MVVM are DataTemplates considered Views as UserControls are Views?

    - by Edward Tanguay
    In MVVM, every View has a ViewModel. A View I understand to be a Window, Page or UserControl to which you can attach a ViewModel from which the view gets its data. But a DataTemplate can also render a ViewModel's data. So I understand a DataTemplate to be another "View", but there seem to be differences, e.g. Windows, Pages, and UserControls can define their own .dlls, one type is bound with DataContect the other through attaching a template so that Windows, Pages, UserControls can can be attached to ViewModels dynamically by a ServiceLocator/Container, etc. How else are DataTemplates different than Windows/Pages/UserControls when it comes to rendering a ViewModel's data on the UI? And are there other types of "Views" other than these four?

  • Mongrel_rails can't find memcache-client

    - by tonisep
    We started to use memcache-client in our rails app and it works just fine with "script/server" but "mongrel_rails start" fails with an error. In environment.rb we define "memcache-client" and version "1.8.1". Gem list shows that the gem is installed: memcache-client (1.8.1). If run with "script/server" everything works but with "mongrel_rails start" it fails with error: no such file to load -- memcache-client Any advice what could be wrong here? Is there something different in the way mongrel_rails loads the gems compared to script/server? Or is my setup just broken?
