  - by randombits

  Is there a way to simply have my blocks and their closing end keyword align properly with vim? If I have a function which is nested with several conditions, things can start to get ugly fast. Can vim save the day?

• RoR - Associations into practise - forms (View)

  - by NicoJuicy

  I'm learning Ruby on Rails. I'm using some associations (has_many :through, ...) But i'm having some problems with it when i'm combining my views. How exactly do i combine these nested forms? Can i do this with partial forms and where do i have to write extra code for this? I have seen examples only use the "view" and others also edit the controller.... An example would be very nice :-)

• PCRE (recursive) pattern that matches a string containing a correctly parenthesized substring. Why d

  - by Anton N. Petrov

  Well, there are other ways (hmmm... or rather working ways) to do it, but the question is why does this one fail? / \A # start of the string ( # group 1 (?: # group 2 [^()]* # something other than parentheses (greedy) | # or \( (?1) \) # parenthesized group 1 ) # -group 2 + # at least once (greedy) ) # -group 1 \Z # end of the string /x Fails to match a string with nested parentheses: "(())"

• format - Help with printing a table

  - by Michael Kohl

  This question will probably end in a facepalm, but I've tried for a while and am still stuck despite reading through the hyperspec. Basically what I want to do is something like (format t "~{|~{ ~5d~}|~%~}" '((1 23 2 312) (23 456 1 7890))) but instead of hard-coding the 5 it should be calculated from the list (length of longest element from any nested list + 1) to give something like | 1 23 2 312| | 23 456 1 7890| Maybe I'm thinking way too complicated here and there is an easier way to do what I want, but I think I ran myself into a mental corner that I can't get out of.

• SQL: How to order values inside group by

  - by Denis Yaremov

  Consider the following MS SQL Server table: ID | X | Y ------+-------+------- 1 | 1 | 1 2 | 1 | 2 3 | 1 | 3 4 | 2 | 40 5 | 2 | 500 6 | 3 | 1 7 | 3 | 100 8 | 3 | 10 I need to select the ID of the row that has the maximum value of Y grouped by x, i.e: ID | X | Y ------+-------+------- 3 | 1 | 3 5 | 2 | 500 7 | 3 | 100 The query will be nested several times so an optimal performance solution is required... Thank you!

  I have a page (telerik:RadPage) containing few grids and some nested controls and I was wondering how I can: have a particular cell in one of the grid make always visible even during scrolling. I am not even sure if it is possible, but the one cell I want visible is the first one I am displaying. Any help is appreciated and all suggestions are welcome. Thanks!

• Maintaining property lists for xCode projects

  - by William Jockusch

  My project currently contains two largish property lists. One is currently 20KB; another is 8KB. So far, I have been maintaining them with xCode's property list editor. This is manageable but also a bit clunky. I am wondering if other people have better ways of doing this? So far, my lists consist of nested arrays of strings. The depth is not uniform.

• Facebook API, export group wall entries

  After trying to find a reference to an API/tutorial to such thing, I have come here. I would like to scan a specific group wall, pulling all posts from it, with PHP or C#.

EDIT: If this is not possible, should I consider cURL as an option?

• Generation of abstract class with JCodeModel

  - by SadJokerBY

  I'm trying to generate top-level abstract class with JCodeModel library, but I can't find any way to change class modifiers. It's possible for nested classes (JDefinedClass API provides methods that get modifiers as parameters). But for creation of top level classes I found only JCodeModel API methods that get fully qualified name with or without ClassType (class/interface/annotation/enum) as parameters. Does anybody can suggest me how to change modifiers of JDefinedClass to make it abstract?

• if with multiple conditions, order of execution

  - by markus

  Hi, In an if statement with multiple conditions is second executed if the outcome is clear after checking the first condition? example: if(i>0 && array[i]==0){ } If I swap the conditions a seg fault may occur for negative values of i but this way the memory debugger doesn't find a problem. Can I be sure that this works always or do have have to use nested if statements?

• Any Javascript optimization benchmarks?

  - by int3

  I watched Nicholas Zakas' talk, Speed up your Javascript, with some interest. I liked how he benchmarked the various performance improvements created by various optimization techniques, e.g. reducing calls to deeply nested objects, changing loops to count down instead of up, etc. I would like to run these benchmarks myself though, to see exactly how our current browsers are faring. I guess it wouldn't be too difficult to cook up some timed loops, but I'd like to know if there are any existing implementations out there.

• Convert any object to pretty HTML in java

  - by ripper234

  How can I convert a given object (in a generic way with reflection) to pretty printable HTML? What ready made library do you recommend that does this? I need support for simple nested objects (as long as they don't create loops in the object graph). I tried to convert it to JSON, but DefaultPrettyPrinter is not HTML friendly.

• SVN: Recurisvely add files?

  - by Mark

  I'm trying svn add *.py --force As the documentation suggests, but I know for a fact it's missing files nested in deeper folders. Why? Is there a standard way to do this with other unix commands too? */*.py will nab a few more files, but it's kind of a pain in the butt to do this for every possible depth.

• what is the equivalent of instruct! method in Nokogiri?

  I'd like to use Nokogiri instead of builder to create an XML document because creating the nested appears easier in Nokogiri (I don't need to create a block for each nest). However, how do I create the equivalent of instruct! using Nokogiri?

• C++ Arrays manipulations (python-like operations)

  - by Linai

  Hi Guys, I'm trying to figure out the best C++ library/package for array manipulations in a manner of python. Basically I need a simplicity like this: values = numpy.array(inp.data) idx1 = numpy.where(values > -2.14) idx2 = numpy.where(values < 2.0) res1 = (values[idx1] - diff1)/1000 res1 = (values[idx2] - diff2)*1000 In python it's just 5 lines, but the simplest way in C++ i can think of is quite a number of nested loops. Pls advise..

• How can I use && in if in Ruby on Rails?

  I tried the following && conditional for my if statement and I get a "bad range" error: <% if (from_today(contact, call.days) == 0..7) && (show_status(contact, call) == 'no status') %> Why and how can I fix it? The only other way I could do it was to have a second nested if statement and break it apart...not pretty :(
