  • How to code an efficient blacklist filter function in php?

    - by achairapart
    So, I have three arrays like this: [items] => Array ( [0] => Array ( [id] => someid [title] => sometitle [author] => someauthor ... ) ... ) and also a string with comma separated words to blacklist: $blacklist = "some,words,to,blacklist"; Now I need to match these words with (as they can be one of) id, title, author and show results accordingly. I was thinking of a function like this: $pattern = '('.strtr($blacklist, ",", "|").')'; // should return (some|words|etc) foreach ($items as $item) { if ( !preg_match($pattern,$item['id']) || !preg_match($pattern,$item['title']) || !preg_match($pattern,$item['author']) ) { // show item } } and I wonder if this is the most efficient way to filter the arrays or I should use something with strpos() or filter_var with FILTER_VALIDATE_REGEXP ... Note that this function is repeated per 3 arrays. However, each array will not contain more than 50 items.

  • Sharing code between two or more rails apps... alternatives to git submodules?

    - by jtgameover
    We have two separate rails_app, foo/ and bar/ (separate for good reason). They both depend on some models, etc. in a common/ folder, currently parallel to foo and bar. Our current svn setup uses svn:externals to share common/. This weekend we wanted to try out git. After much research, it appears that the "kosher" way to solve this is using git submodule. We got that working after separating foo,bar,common into separate repositories, but then realized all the strings attached: Always commit the submodule before committing the parent. Always push the submodule before pushing the parent. Make sure that the submodule's HEAD points to a branch before committing to it. (If you're a bash user, I recommend using git-completion to put the current branch name in your prompt.) Always run 'git submodule update' after switching branches or pulling changes. All these gotchas complicate things further than add,commit,push. We're looking for simpler ways to share common in git. This guy seems to have success using the git subtree extension, but that deviates from standard gitand still doesn't look that simple. Is this the best we can do given our project structure? I don't know enough about rails plugins/engines, but that seems like a possible RoR-ish way to share libraries. Thanks in advance.

  • Why does Python's 'for ... in' work differently on a list of values vs. a list of dictionaries?

    - by Code Duck
    I'm wondering about some details of how for ... in works in Python. My understanding is for var in iterable on each iteration creates a variable, var, bound to the current value of iterable. So, if you do for c in cows; c = cows[whatever], but changing c within the loop does not affect the original value. However, it seems to work differently if you're assigning a value to a dictionary key. cows=[0,1,2,3,4,5] for c in cows: c+=2 #cows is now the same - [0,1,2,3,4,5] cows=[{'cow':0},{'cow':1},{'cow':2},{'cow':3},{'cow':4},{'cow':5}] for c in cows: c['cow']+=2 # cows is now [{'cow': 2}, {'cow': 3}, {'cow': 4}, {'cow': 5}, {'cow': 6}, {'cow': 7} #so, it's changed the original, unlike the previous example I see one can use enumerate to make the first example work, too, but that's a different story, I guess. cows=[0,1,2,3,4,5] for i,c in enumerate(cows): cows[i]+=1 # cows is now [1, 2, 3, 4, 5, 6] Why does it affect the original list values in the second example but not the first?

  • PHP & JavaScript source code formatters (prettifiers) - NATIVE only apps!

    - by vic
    Hi, I know at least two PHP source prettifiers and one for JavaScript, but all of them are written in those languages - PHP prettifiers in PHP, JavaScript in JS ;] Now what I'm looking for is a prettifier for those languages which is a native application - can be C/C++ or Pascal, so that I can run it from commandline. Possibly open source solution, as I might need to modify it a bit for my needs ... ( i need to run those prettifiers in batch mode ) any known programs / libraries for that?

  • In Silverlight 3 how can I get the call to HtmlPage.Plugin.SetStyleAttribute() call to call other co

    - by John Rennemeyer
    I'm trying to take a snapshot of my Silverlight control using WriteableBitmap and it works fine, however, it only takes a snapshot of what is showing. I'm trying to resize the Silverlight control so it will show everything and then take a screenshot, however, the code doesn't resize the control until after the code after the call all runs which is the snapshot code... I can get this work using a timer to fire the snapshot after the other code has caused the resize but I'm wondering if there is a better way. The HtmlPage.Plugin.SetStyleAttribute call has to be called from the UI thread so I'm assuming that's where the problem is. The fact that it is being dispatched onto the UI thread while the rest of the code is not and so the other code is being run first. Is there anyway to create a new event or attach to the call to determine when it has been run to then fire off my snapshot code? I have the following code: private void btnTakeSnapshot_Click(object sender, System.Windows.RoutedEventArgs e) { if (CurrentContractAction != null) { string heightBefore = HtmlPage.Plugin.GetStyleAttribute("height"); HtmlPage.Plugin.SetStyleAttribute("height", string.Format("{0}px", "1800")); //this line doesn't change the height until after the "TakeSnapshot" code is run for some reason, I'm thinking it is because it is most likely dispatched to the UI thread :( and the following code is not run on the UI thread Snapshot snapshot = new Snapshot(string.Format("Action_Schedule_{0}", CurrentContractAction.Title), LayoutRoot, LayoutRoot, busyIndicatorDataGrid); snapshot.HideElements(btnViewGanttChart, btnSave, btnEditAction, btnFullScreen, btnTakeSnapshot, btnLockAndSubmit); snapshot.TakeSnapshot(); snapshot.ResetElementsVisibility(); HtmlPage.Plugin.SetStyleAttribute("height", string.Format("{0}px", heightBefore)); } } Thanks, John

  • I have to generate PL/SQL using Java. Most of the procedures are common. Only a few keeps changing.

    - by blog
    I have to generate PL-SQL code, with some common code(invariable) and a variable code. I don't want to use any external tools. Some ways that I can think: Can I go and maintain the common code in a template and with markers, where my java code will generate code in the markers and generate a new file. Maintain the common code in static constant String and then generate the whole code in StringBuffer and at last write to file. But, I am not at all satisfied with both the ideas. Can you please suggest any better ways of doing this or the use of any design patterns or anything? Thanks in Advance.

  • What is the most efficient functional version of the following imperative code?

    - by justin.r.s.
    I'm learning Scala and I want to know the best way of expressing this imperative pattern using Scala's functional programming capabilities. def f(l: List[Int]): Boolean = { for (e <- l) { if (test(e)) return true } } return false } The best I can come up with is along the lines of: l map { e => test(e) } contains true But this is less efficient since it calls test() on each element, whereas the imperative version stops on the first element that satisfies test(). Is there a more idiomatic functional programming technique I can use to the same effect? The imperative version seems awkward in Scala.

  • How can I bind dynamic data to DataGridTemplateColun in code?

    - by TuomoT
    I'm using DataGrid from CodePlex. I have objects (ICustomTypeDescriptor) that have properties 'name' 'description' 'c' 'd' and so on (the names are dynamic, and so is the value) and they have information behind them. I have templates for different types. And if I have to list the properties of a single element I can just bind to the values in xaml and use datatemplateselector (in datagridtemplatecolumn) which will pick the correct template. However, when I'm listing several of the elements, how can I use the selectors and the templates? How do I get the correct property bound to the template (two-way)? When ignoring the need for different templates, using DataGridTextColumn with bindings is very simple (and works, see example below), is there any way to use similar approach with the DataGridTemplateColumn? foreach (String propertyName in listOfPropertyNames) { DataGridTextColumn textColumn = new DataGridTextColumn() { Header = propertyName, Binding = new Binding() { Path = new PropertyPath(propertyName) } }; DataGrid.Columns.Add(textColumn); }

  • How to understand the functional programming code for converting IP string to a number?

    - by zfz
    In a python discusion, I saw a way to convert IP string to a integer in functional progamming way. Here is the Link . The function is implemented in a single line. def ipnumber(ip): return reduce(lambda sum, chunk: sum <<8 | chunk, map(int, ip.split("."))) However, I have few ideas of funcional programming. Could anybody explain the function in detail? I've some knowledg of "map" and "reduce". But I don't konw what "|" and "chunk" mean here? Thanks.

  • Removing a Subversion folder from the client and server

    - by Code Sherpa
    Hi. I have been using Subversion for a few days now and have a question... I have a folder deep in my subversion trunk that I want to remove and replace with another folder. I have read about this on here and tried: Export: I clicked on the folder I wanted to remove I then created a new backup folder elsewhere when prompted I then exported Delete: I next chose the delete option (in TortoiseSVN) on the folder I wanted to remove and clicked it. The folder I want to remove now has an "X" over it as does all of the subfolders and files. But, when I go to the Subversion repository on the remote server, I still see the folder I want to remove and all of its files. What do I have to do to get the clients to forget about this folder and the Subversion server to remove it permanently from its sub-folders? Thanks in advance...

  • How do I assign a value from params, or session, whichever exists?

    - by irkenInvader
    What is the "Rails-way" or the "Ruby-way" of doing the following: In my controller, I'm creating and instance of an Options class. It will be initialized with information in the params hash if the params hash exists. Otherwise, it will check the sessions hash for the information. Finally, it will initialize with defaults if neither params nor session has the data it needs. Here is how I'm doing it now (it works fine, but it seems a little ugly): if params[:cust_options] @options = CustomOptions.new( params[:cust_options] ) else if session[:cust_options @options = CustomOptions.new( session[:cust_options] ) else @options = CustomOptions.new end end session[:cust_options] = @options.to_hash Like I said, everything is working fine, I'm just looking for a more idiomatically Ruby way of writing this block of code.

  • Detect whether or not a specific attribute was valid on the model

    - by Sir Code-A-Lot
    Having created my own validation attribute deriving from System.ComponentModel.DataAnnotations.ValidationAttribute, I wish to be able to detect from my controller, whether or not that specific attribute was valid on the model. My setup: public class MyModel { [Required] [CustomValidation] [SomeOtherValidation] public string SomeProperty { get; set; } } public class CustomValidationAttribute : ValidationAttribute { public override bool IsValid(object value) { // Custom validation logic here } } Now, how do I detect from the controller whether validation of CustomValidationAttribute succeeded or not? I have been looking at the Exception property of ModelError in the ModelState, but I have no way of adding a custom exception to it from my CustomValidationAttribute. Right now I have resorted to checking for a specific error message in the ModelState: public ActionResult PostModel(MyModel model) { if(ModelState.Where(i => i.Value.Errors.Where((e => e.ErrorMessage == CustomValidationAttribute.SharedMessage)).Any()).Any()) DoSomeCustomStuff(); // The rest of the action here } And changed my CustomValidationAttribute to: public class CustomValidationAttribute : ValidationAttribute { public static string SharedMessage = "CustomValidationAttribute error"; public override bool IsValid(object value) { ErrorMessage = SharedMessage; // Custom validation logic here } } I don't like relying on string matching, and this way the ErrorMessage property is kind of misused. What are my options?

  • How to retain a row which is foreign key in another table and remove other duplicate rows?

    - by Mithril
    I have two table: A: id code 1 A1 2 A1 3 B1 4 B1 5 C1 6 C1 ===================== B: id Aid 1 1 2 4 (B doesn't contain the Aid which link to code C1) Let me explain the overall flow: I want to make each row in table A have different code(by delete duplicate),and I want to retain the Aid which I can find in table B.If Aid which not be saved in table B,I retain the id bigger one. so I can not just do something as below: DELETE FROM A WHERE id NOT IN (SELECT MAX(id) FROM A GROUP BY code, ) I can get each duplicate_code_groups by below sql statement: SELECT code FROM A GROUP BY code HAVING COUNT(*) > 1 Is there some code in sql like for (var ids in duplicate_code_groups){ for (var id in ids) { if (id in B){ return id } } return max(ids) } and put the return id into a idtable?? I just don't know how to write such code in sql. then I can do DELETE FROM A WHERE id NOT IN idtable

  • How can I use a value of JSP in Javascript code?

    - by novellino
    Hello, I have a list of elements, each of them appeared in my page through jsp. So I have this: <div id="title"><%= list.get(ind).getTitle() %></div> When I display the elements, as this tag is in for loop, I get everything right. Now I what to place a button for deleting each of this elements. What I have done is: <input type="submit" name="submit" onclick="deleteNewsFunction();" id="submit_btn"/> In the deleteNewsFunction() I just want to print the data. <script> function deleteNewsFunction(){ var item = $('#title').val(); alert(item); } </script> The problem is that the title var gets always the first item even if I am clicking on the button of the second item. I was thinking that maybe a solution is to add the "list.get(ind).getTitle()" as a parameter in the function like deleteNewsFunction(<%=list.get(ind).getTitle()%) but then it did not work at all. Does anyone know how to help me? Thanks a lot!
