  • 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!

  • An Inaccessible JavaScript Object property - Why is Firebug showing this?

    - by Matty
    So, I'm attempting to access the content of an object and for the life of me can't figure out why I can't. I'm starting to believe that the object doesn't have the properties that Firebug indicates that it does. More likely than that I'm just not using the right syntax to access them. Give the following function: function(userData) { console.log(userData); // statement 1 console.log(userData.t_nodecontent); // statement 2 } Which generates the following FireBug output for statement 1 and unknown for statement 2. Is there something obvious that I'm overlooking in the way I'm attempting to reference the value of t_nodecontent? I'm at a loss :(

  • Sending variables in URLs in PHP with echo

    - by alexpelan
    Hi all, I can't really find good guidelines through google searches of the proper way to escape variables in URLs. Basically I am printing out a bunch of results from a mysql query in a table and I want one of the entries in each row to be a link to that result's page. I think this is easy, that I'm just missing a apostrophe or backslash somewhere, but I can't figure it out. Here's the line that's causing the error: echo "<a href = \"movies.php/?movie_id='$row['movie_id']'\"> Who Owns It? </a> "; and this is the error I'm getting: Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING If you could elaborate in your answers about general guidelines for working with echo and variables in urls, that would be great. Thanks.

  • Real world examples of Ecmascript functions returning a Reference?

    - by Bergi
    Read the EcmaScript specification, section 8.7 The Reference Specification Type: The Reference type is used to explain the behaviour of such operators as delete, typeof, and the assignment operators. […] A Reference is a resolved name binding. Function calls are permitted to return references. This possibility is admitted purely for the sake of host objects. No built-in ECMAScript function defined by this specification returns a reference and there is no provision for a user-defined function to return a reference. Those last two sentences impressed me. With this, you could do things like coolHostFn() = value (valid syntax, btw). So my question is: Are there any EcmaScript implementations that define host function objects which result in Reference values?

  • How to sort a list by the 2nd tuple element in python and C#

    - by user350468
    I had a list of tuples where every tuple consists of two integers and I wanted to sort by the 2nd integer. After looking in the python help I got this: sorted(myList, key=lambda x: x[1]) which is great. My question is, is there an equally succinct way of doing this in C# (the language I have to work in)? I know the obvious answer involving creating classes and specifying an anonymous delegate for the whole compare step but perhaps there is a linq oriented way as well. Thanks in advance for any suggestions.

  • 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?

  • How do you make Python wait so that you can read the output?

    - by anonnoir
    I've always been a heavy user of Notepad2, as it is fast, feature-rich, and supports syntax highlighting. Recently I've been using it for Python. My problem: when I finish editing a certain Python source code, and try to launch it, the screen disappears before I can see the output pop up. Is there any way for me to make the results wait so that I can read it, short of using an input() or time-delay function? Otherwise I'd have to use IDLE, because of the output that stops for you to read. (My apologies if this question is a silly one, but I'm very new at Python and programming in general.)

  • Use where condition with unjoined table

    - by Dragos D
    I have the following problem: I am trying to retreive a sum value based on one condition. Problem is that I can't join the conditional value since my tables aren't joined. Here is my syntax: SELECT SUM(value) FROM value v join day d on v.day_id = d.day_id join budget b on d.budget_id = b.budget_id join unit u on v.unit_id = u.unit_id where #output.class = (SELECT distinct s.class FROM sale s where s.id = #output.sale_id) AND u.unit_name in ('electronics') With this sybtax I get no error but neither values. Can you please tell me where I do wrong?

  • 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!

  • How can I programmatically 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.

  • Which external DSLs do you like to use?

    - by Max Toro
    The reason I'm asking is because right now there seems to be tendency to make DSLs internal. One example is LINQ in C# and VB. You can use it against in-memory objects, or you can use it as a replacement of SQL or other external DSL. Another example is HTML5 vs XHTML2. XHTML2 supported decentralized extensibility through namespaces, in other words you embed external DSL code (XForms, SVG, MathML, etc.) in your XHTML code. Sadly HTML5 doesn't seem to have such mechanism, instead new features are internal (e.g. <canvas> instead of SVG). I'd like to know what other developers think about this. Do you like using external DSLs ? Which ones ? If not, why ?

  • Too Many Left Outer Joins in Entity Framework 4?

    - by Adam
    I have a product entity, which has 0 or 1 "BestSeller" entities. For some reason when I say: db.Products.OrderBy(p = p.BestSeller.rating).ToList(); the SQL I get has an "extra" outer join (below). And if I add on a second 0 or 1 relation ship, and order by both, then I get 4 outer joins. It seems like each such entity is producing 2 outer joins rather than one. LINQ to SQL behaves exactly as you'd expect, with no extra join. Has anyone else experienced this, or know how to fix it? SELECT [Extent1].[id] AS [id], [Extent1].[ProductName] AS [ProductName] FROM [dbo].[Products] AS [Extent1] LEFT OUTER JOIN [dbo].[BestSeller] AS [Extent2] ON [Extent1].[id] = [Extent2].[id] LEFT OUTER JOIN [dbo].[BestSeller] AS [Extent3] ON [Extent2].[id] = [Extent3].[id] ORDER BY [Extent3].[rating] ASC

  • Lambda expressions - set the value of one property in a collection of objects based on the value of

    - by Michael Rut
    I'm new to lambda expressions and looking to leverage the syntax to set the value of one property in a collection based on another value in a collection Typically I would do a loop: class item{ public string name {get;set;} public string value {get;set;} } class business { item item1 = new item(name="name1"); item item2 = new item(name="name2"); item item3 = new item(name="name3"); Collection<item> items = new Collection() {item1,item2,item3}; //This is what I want to simplify for( int i = 0; i < items.count; i++) { if(items[i].item.name == "name2") { //set the value items[i].item.value = "value2"; } } }

  • Scala Tuple Deconstruction

    - by dbyrne
    I am new to Scala, and ran across a small hiccup that has been annoying me. Initializing two vars in parallel works great: var (x,y) = (1,2) However I can't find a way to assign new values in parallel: (x,y) = (x+y,y-x) //invalid syntax I end up writing something like this: val xtmp = x+y; y = x-y; x = xtmp I realize writing functional code is one way of avoiding this, but there are certain situations where vars just make more sense. I have two questions: 1) Is there a better way of doing this? Am I missing something? 2) What is the reason for not allowing true parallel assignment?

  • 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?

  • How do I set a variable inside a bash for loop?

    - by Isaac Moore
    I need to set a variable inside of a bash for loop, which for some reason, is not working for me. Here is an excerpt of my script: function unlockBoxAll { appdir=$(grep -i "CutTheRope.app" /tmp/App_list.tmp) for lvl in {0..24} key="UNLOCKED_$box_$lvl" plutil -key "$key" -value "1" "$appdir/../Library/Preferences/com.chillingo.cuttherope.plist" 2>&1> /dev/null successCheck=$(plutil -key "$key" "$appdir/../Library/Preferences/com.chillingo.cuttherope.plist") if [ "$successCheck" -eq "1" ]; then echo "Success! " else echo "Failed: Key is $successCheck " fi done } As you can see, I try to write to a variable inside the loop with: key="UNLOCKED_$box_$lvl" But when I do that, I get this: /usr/bin/cutTheRope.sh: line 23: syntax error near unexpected token `key="UNLOCKED_$box_$lvl"' /usr/bin/cutTheRope.sh: line 23: `key="UNLOCKED_$box_$lvl"' What am I not doing right? Is there another way to do this? Please help, thanks.

  • In C#, What is <T> After a Method Declaration?

    - by Drew
    I'm a VB.Net guy. (because I have to be, because the person who signs my check says so. :P) I grew up in Java and I don't generally struggle to read or write in C# when I get the chance. I came across some syntax today that I have never seen, and that I can't seem to figure out. In the following method declaration, what does < T represent? static void Foo < T (params T[] x) I have seen used in conjunction with declaring generic collections and things, but I can't for the life of me figure out what it does for this method. In case it matters, I came across it when thinking about some C# brain teasers. The sixth teaser contains the entire code snippet.

  • 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.. :)

  • 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?

  • Setting button width with fx:Style

    - by Kamo
    I have 4 buttons, all of them have the same width. <s:Button id="btn1" width="{btnWidth}" /> <s:Button id="btn2" width="{btnWidth}" /> <s:Button id="btn3" width="{btnWidth}" /> <s:Button id="btn4" width="{btnWidth}" /> Is it possible to set their width with Style, something like this: s|Button{ width: btnWidth; } I tried it, but auto-complete isn't working, which leads me to think that there's something wrong with the syntax. Basically my goal is to not have the width property set specifically for all 4.

  • Is there a way to make XmlDocument parsing less strict

    - by Istrebitel
    I am making a program that will store its data in an XML file. When people write XML they can make subtle mistakes, like ending a comment with - so it looks like <!-- comment ---> or adding a </>inside an attribute. Naturally, the XML still can be read all right, but trying to input this text into XmlDocument will give a syntax error (and it wont be parsed). Is there a way to make XmlDocument less strict and make it ignore violations of the standard that do not make the document unparseable? For example, its clear that <!-- comment ---> is still a comment even though it contains - at the end which is against the standard specification).

  • Perl to output processed XML file encoded as UTF-8 with UNIX line endings (in Win32 environment)?

    - by Umber Ferrule
    Running ActiveState Perl 5.8.8 on WinXP. As the title suggests, I'd like to output an XML file as UTF-8 with UNIX line endings. I've looked at the PerlDoc for binmode, but am unsure of the exact syntax (if I'm not barking up the wrong tree). The following doesn't do it (forgive my Perl - it's a learning process!): sub SaveFile { my($FileName, $Contents) = @_; my $File = "SAVE"; unless( open($File, ">:utf-8 :unix", $FileName) ) { die("Cannot open $FileName"); } print $File @$Contents; close($File); } Any suggestions? Thanks.
