  • 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!

  • Nginx redirect if cookie present

    - by Joseph Silvashy
    I've seen some limited resources on checking for cookies with Nginx, but I couldn't really find the answer I was looking for, hopefully some of you Nginx masters can give me a hand. Essentially I have a vhost that I'd like to redirect to a different domain unless the user has a cookie, here is what I've created: server { listen 80; server_name rerecipe.com; if ($http_cookie ~* "ngl_beta_pass" ) { # set $beta off; root /home/deploy/apps/rerecipe/current/public; passenger_enabled on; rack_env production; break; } rewrite ^/(.*) http://beta.rerecipe.com/$1 permanent; } But it doesn't seem to work, I get the error: [emerg]: "root" directive is not allowed here in /opt/nginx/conf/nginx.conf:45 I'm not sure how to proceed here, any ideas guys?

  • Fastest way to check a List<T> for a date

    - by fishhead
    I have a list of dates that a machine has worked on, but it doesn't include a date that machine was down. I need to create a list of days worked and not worked. I am not sure of the best way to do this. I have started by incrementing through all the days of a range and checking to see if the date is in the list by iterating through the entire list each time. I am looking for a more efficient means of finding the dates. class machineday { datetime WorkingDay; } class machinedaycollection : List<machineday> { }

  • Problem with parsing SQL into table variable

    I'm using the following code to read a SQL XML Variable into a table variable. I am getting the following error. " Incorrect syntax near '.'.

  • Template engine recommendations

    - by alex
    I'm looking for a template engine. Requirements: Runs on a JVM. Java is good; Jython, JRuby and the like, too... Can be used outside of servlets (unlike JSP) Is flexible wrt. to where the templates are stored (JSP and a lot of people require the templates to be stored in the FS). It should provide a template loading interface which one can implement or something like that Easy inclusion of parameterized templates- I really like JSP's tag fragments Good docs, nice code, etc., the usual suspects I've looked at JSP- it's nearly perfect except for the servlet and filesystem coupling, Stringtemplate- I love the template syntax, but it fails on the filesystem coupling, the documentation is lacking and template groups and stuff are confusing, GXP, TAL, etc. Ideas, thoughts?

  • How can I create a custom cleanup mode for git?

    - by Danny
    Git's default cleanup of strip removes all lines starting with a # character. Unfortunately, the Trac engine's wiki formatter uses hashes in the beginning of a code block to denote the syntax type. Additionally any code added verbatim might include hashes as they are a common comment prefix; Perl comes to mind. In the following example the comments all get destroyed by git's cleanup mode. Example: {{{ #!/usr/bin/perl use strict; # say hi to the user. print "hello world\n"; }}} I'd like to use a custom filter that removes all lines beginning with a hash from the bottom of the file upwards. Leaving those lines that being with a hash that are embedded in the commit message I wrote alone. Where or how can I specify this in git? Note, creating a sed or perl script to perform the operation is not a problem, just knowing where to hook it into git is the question.

  • SQL query: how to translate IN() into a JOIN?

    - by tangens
    I have a lot of SQL queries like this: SELECT o.Id, o.attrib1, o.attrib2 FROM table1 o WHERE o.Id IN ( SELECT DISTINCT Id FROM table1, table2, table3 WHERE ... ) These queries have to run on different database engines (MySql, Oracle, DB2, MS-Sql, Hypersonic), so I can only use common SQL syntax. Here I read, that with MySql the IN statement isn't optimized and it's really slow, so I want to switch this into a JOIN. I tried: SELECT o.Id, o.attrib1, o.attrib2 FROM table1 o, table2, table3 WHERE ... But this does not take into account the DISTINCT keyword. Question: How do I get rid of the duplicate rows using the JOIN approach?

  • Is there a more correct type for passing in the file path and file name to a method

    - by Rihan Meij
    Hi What I mean by this question is, when you need to store or pass a URL around, using a string is probably a bad practice, and a better approach would be to use a URI type. However it is so easy to make complex things more complex and bloated. So if I am going to be writing to a file on disk, do I pass it a string, as the file name and file path, or is there a better type that will be better suited to the requirement? This code seems to be clunky, and error prone? I would also need to do a whole bit of checking if it is a valid file name, if the string contains data and the list goes on. private void SaveFile(string fileNameAndPath) { //The normal stuff to save the file }

  • SELECT(IF(IN query.

    - by Harold
    There are 3 tables. Products, Options and Prod_Opts_relations. The latter holds product_id and option_id so i should be able to figure out which options are selected for any given product. Now i want to retrieve all options from the options table where the value of an extra alias field should hold checked or unchecked depending on the existance of a mathing record in the relations table for a give product id. Thus far i came up with this: SELECT IF(IN(SELECT id_option FROM prod_opt_relations WHERE id_product='18'),'y','n') AS booh ,optionstable.id AS parent_id ,optionstable.name_en AS parent_english ,optionstable.name_es AS parent_spanish FROM product_options AS optionstable WHERE 1 resulting in syntax errors. Alas i just cannot figure out where things go wrong here

  • ASP.NET DropDownList Replacement

    - by user302004
    Currently, I'm populating a drop down list when a file is created in a configurable folder. if (!downloadRspDropDown.Items.Contains(new ListItem(txt, fileData.FullName)) Then, I add the file and remove "No Responses Available". However, if the same file is resubmitted (i.e., the file name is the same but the timestamp is different), then I want to remove the older entry and replace it with a new entry in the drop down list. I have the filename, so I go into the "else" block from the line of code above. From there, I'm checking to see if I have the same filename and a different creation time. if (downloadRspDropDown.Items.Contains(new ListItem(txt, fileData.FullName) && downloadRspDropDown.Items.Contains(new ListItem(txt, fileData.CreationTime) From here, I want to find the position, remove it, and add the new text. This approach isn't working. Can anyone offer an alternate approach?

  • What TypeScript pattern can I use to enforce that a function gets a property?

    - by Matt York
    In JavaScript I can do this: function f() {} f.prop = "property"; I want this in TypeScript, but with type checking. What TypeScript pattern can I use to enforce that a function gets a property? Could I use an interface? interface functionWithProperty { (): any; prop: string; } This seems to be a valid interface in TypeScript, but how do I implement this interface such that the TypeScript compiler checks that prop is set? I saw this example: var f : functionWithProperty = (() => { var _f : any = function () { }; _f.prop = "blah"; return _f; }()); But this doesn't work because I can remove _f.prop = "blah"; and everything will still compile. I need to enforce that prop is set.

  • How does R treat positional arguments

    - by inspectorG4dget
    I'm a python guy and very new to R (so far, all I've done is copy-paste code and screen-shot the resulting, graph). I would now like to actually learn the language so that I can draw useful plots (right now, I am trying to plot this). In attempting my first plot, I came across this function call: sets_options("universe", seq(from = 0, to = 25, by = 0.1)) Now, I would like to know if I can achieve the same result by calling sets_options("universe", seq(0, 25, 0.1)) The help page for seq doesn't speak to this specifically (or I'm not reading it correctly), so I was hoping someone could shed some light on how R handles positional arguments I tried calling the function that way in R and it worked (no syntax errors, etc), but I don't know how to test the output of that function, so I'm forced to ask here

  • get entire line with java.util.scanner.hasNext(regex)

    - by Hussain
    I'm doing something in Java that requires input to be matched against the pattern ^[1-5]$. I should have a while loop looping through each line of input, checking it against the pattern, and outputting an error message if it does not. Sudo code: while (regex_match(/^[^1-5]$/,inputLine)) { print ("Please enter a number between 1 and 5! "); getNextInputLine(); } I can use java.util.Scanner.hasMatch("^[^1-5]$"), but that will only match a single token, not the entire line. Any idea on how to make hasMatch match against the entire line? (Setting the delimiter to "\n" or "\0" doesn't work.)

  • Is there a function that can read a php function post-parsing?

    - by Rob
    I've got a php file echoing hashes from a MySQL database. This is necessary for a remote program I'm using, but at the same time I need my other php script opening and checking it for specified strings POST parsing. If it checks for the string pre-parsing, it'll just get the MySQL query rather than the strings to look for. I'm not sure if any functions do this. Does fopen() read the file prior to parsing? or file_get_contents()? If so, is there a function that'll read the file after the php and mysql code runs? The file with the hashes query and echo is in the same directory as the php file reading it, if that makes a difference. Perhaps fopen reads it post-parse, and I've done something wrong, but at first I was storing the hashes directly in the file, and it was working fine. After I changed it to echo the contents of the MySQL table, it bugged out.

  • MyFaces Test Framework not working with JSF 2.1

    - by Karl Kildén
    we have a lot of tests that uses Myfaces Test Framework for JSF 2.0. http://myfaces.apache.org/test/index.html Problem is we can't get it to work with JSF 2.1. Does anyone know a workaround or a way to solve this? When we run the tests we get the following error: java.lang.IllegalStateException: Application was not properly initialized at startup, could not find Factory: javax.faces.application.ApplicationFactory It works fine with jsf 2.0 though. A typical use case in our code: // code block; assertFalse("Error message not expected. ", facesContext .getMessages().hasNext()); JSF 2.1 has a few syntax changes so my guess would be that's the problem.

  • Grails unit testing domain classes with Set properties - is this safe?

    - by Ali G
    I've created a domain class in Grails like this: class MyObject { static hasMany = [tags: String] // Have to declare this here, as nullable constraint does not seem to be honoured Set tags = new HashSet() static constraints = { tags(nullable: false) } } Writing unit tests to check the size and content of the MyObject.tags property, I found I had to do the following: assertLength(x, myObject.tags as Object[]) assertEquals(new HashSet([...]), myObject.tags) To make the syntax nicer for writing the tests, I implemented the following methods: void assertEquals(List expected, Set actual) { assertEquals(new HashSet(expected), actual) } void assertLength(int expected, Set set) { assertLength(expected, set as Object[]) } I can now call the assertLength() and assertEquals() methods directly on an instance of Set, e.g. assertLength(x, myObject.tags) assertEquals([...], myObject.tags) I'm new to Groovy and Grails, so unaware how dangerous method overloading like this is. Is it safe? If so, I'm slightly* surprised that these methods (or similar) aren't already available - please let me know if they are. * I can see how these methods could also introduce ambiguity if people weren't expecting them. E.g. assertLength(1, set) always passes, no matter what the content of set

  • Dynamically reducing image dimension as well as image size in C#

    - by hanesjw
    I have an image gallery that is created using a repeater control. The repeater gets bound inside my code behind file to a table that contains various image paths. The images in my repeater are populated like this <img src='<%# Eval("PicturePath")' %>' height='200px' width='150px'/> (or something along those lines, I don't recall the exact syntax) The problem is sometimes the images themselves are massive so the load times are a little ridiculous. And populating a 150x200px image definitely should not require a 3MB file. Is there a way I can not only change the image dimensions, but shrink the file size down as well? Thanks!

  • Can a rake task know about the other tasks in the invocation chain?

    - by andrewdotnich
    Rake (like make) is able to have many targets/tasks specified on invocation. Is it possible for a rake task to access the list of tasks the user invoked, in order to do its job? Scenario: Consider a Rake-based build tool. A help task would like to know what tasks were also specified in order to print their usage and halt the build process. The benefit of this as opposed to rake-style parameter passing are cleaner syntax (rake help build instead of rake help task=build) and chaining (rake help build run_tests would print usage for both).

  • very weird problem concerning date and time in silverlight + ria services

    - by Patrick LHM
    Hello Friends i'm facing a very weird problem in sliverlight 4 + RIA Services, or maybe it's not weird and i'm just a newbie anyway i hope someone here can help, the problem is the following i've created a function on the server side inside the domain service this function is very simple and has a line in it that adds the server current date and time to the database (it's an HR application and employees should sign in and out thrue it each from it's own pc ) Emp.TimeOut = system.DateTime.now (C# syntax) the weird part is that for some users it always adds 3 hours to the current time(exp if he signes out at 5 it shows 8) and for others it works perfectly. the server and all the stations in the company have exactly the same time settings and the same time zone, and anyway my fucntion is on the server side so it should no be realted to the users time. any ideas why this is happening ? i've bin trying to find out why for days now but with no luck

  • Pure functional bottom up tree algorithm

    - by Axel Gneiting
    Say I wanted to write an algorithm working on an immutable tree data structure that has a list of leaves as its input. It needs to return a new tree with changes made to the old tree going upwards from those leaves. My problem is that there seems to be no way to do this purely functional without reconstructing the entire tree checking at leaves if they are in the list, because you always need to return a complete new tree as the result of an operation and you can't mutate the existing tree. Is this a basic problem in functional programming that only can be avoided by using a better suited algorithm or am I missing something?

  • Need a good way to share iPhone source code on the Web.

    - by CJCraft.com
    Hi, I'm looking for a way to share some iPhone SDK source code I have with others. Goals: Share iPhone SDK source code, Objective C written in XCode. I have a good bit of source code I want to share. I'd like for it to be easy. I'd like for it to have syntax highlighting, by this I mean coloring and formatting Ideally it would allow me some room to make it "fit" into my site. I want it to look like basically another page on my site where the content is the code. It shouldn't be just a text file in other words. Here's an example where someone was able to do this for C#: http://www.opennetcf.com/library/sdf/ I guess what I want is the ability to create html documentation for all the classes, etc.

  • 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?
