  • Parsing a file with hierarchical structure in Python

    - by Kevin Stargel
    I'm trying to parse the output from a tool into a data structure but I'm having some difficulty getting things right. The file looks like this: Fruits Apple Auxiliary Core Extras Banana Something Coconut Vegetables Eggplant Rutabaga You can see that top-level items are indented by one space, and items beneath that are indented by two spaces for each level. The items are also in alphabetical order. How do I turn the file into a Python list that's something like ["Fruits", "Fruits/Apple", "Fruits/Banana", ..., "Vegetables", "Vegetables/Eggplant", "Vegetables/Rutabaga"]?

  • Treeview drag and drop

    - by David Thorisson
    I'm using the jQuery droppable/dragable to reorder a treeview (made up of ul/li items) I have no problems making a element and dragging it into the tree When I define the items to be draggable, the code doesn´t work any more (the items are classed as "droppables" but the drop event won´t run) Isn't this supposed to be possible?

  • Servlet, JSP, JavaBeans and HTML form

    - by dedalo
    Hi, I'm working on a servlet that makes a connection to a database gets the information of one of the tables ans sends this information to a jsp file. This file will print on the brower the information table, adding radio buttons that allows us to choose one of the rows. The servlet looks like this: List<InfoBean> items = new ArrayList<InfoBean>(); if (!conexion.isClosed()){ Statement st = (Statement) conexion.createStatement(); ResultSet rs = st.executeQuery("select * from lista_audio" ); while (rs.next()) {items.add(getRow(rs));} conexion.close();} req.getSession().setAttribute("items", items); In the JSP file I can print a table with the information, adding radio buttons that the user will use to choose 1 row and send the selected info to a servlet using a form I can add: < form action="administ" method=get enctype=multipart/form-data> < table> < table border=\"1\">< tr>< th>Title< /th>< th>Author< /th>< th>Album< /th>< /tr> < c:forEach items="${items}" var="item"> < tr>< td><input type="radio" name="SongInfo" value=${item.title}> < td>${item.title}< /td> < td>${item.author}< /td> < td>${item.album}< /td>< /tr> < /c:forEach> < /table> In the field 'value' I should be able to send to the servlet the information stored in ${item.title}. When I set value = ${item.title} and title is, for example "The bodyguard", in the servlet the information I can retrieve is just "The". It looks like it sends the characters located before the first white space of the string. How could I get the whole string? Thanks

  • Clojure agents consuming from a queue

    - by erikcw
    I'm trying to figure out the best way to use agents to consume items from a Message Queue (Amazon SQS). Right now I have a function (process-queue-item) that grabs an items from the queue, and processes it. I want to process these items concurrently, but I can't wrap my head around how to control the agents. Basically I want to keep all of the agents busy as much as possible without pulling to many items from the Queue and developing a backlog (I'll have this running on a couple of machines, so items need to be left in the queue until they are really needed). Can anyone give me some pointers on improving my implementation? (def active-agents (ref 0)) (defn process-queue-item [_] (dosync (alter active-agents inc)) ;retrieve item from Message Queue (Amazon SQS) and process (dosync (alter active-agents dec))) (defn -main [] (def agents (for [x (range 20)] (agent x))) (loop [loop-count 0] (if (< @active-agents 20) (doseq [agent agents] (if (agent-errors agent) (clear-agent-errors agent)) ;should skip this agent until later if it is still busy processing (not sure how) (send-off agent process-queue-item))) ;(apply await-for (* 10 1000) agents) (Thread/sleep 10000) (logging/info (str "ACTIVE AGENTS " @active-agents)) (if (> 10 loop-count) (do (logging/info (str "done, let's cleanup " count)) (doseq [agent agents] (if (agent-errors agent) (clear-agent-errors agent))) (apply await agents) (shutdown-agents)) (recur (inc count)))))

  • Flexible Decorator Pattern?

    - by Omar Kooheji
    I was looking for a pattern to model something I'm thinking of doing in a personal project and I was wondering if a modified version of the decorator patter would work. Basicly I'm thinking of creating a game where the characters attributes are modified by what items they have equiped. The way that the decorator stacks it's modifications is perfect for this, however I've never seen a decorator that allows you to drop intermediate decorators, which is what would happen when items are unequiped. Does anyone have experience using the decorator pattern in this way? Or am I barking up the wrong tree? Clarification To explain "Intermediate decorators" if for example my base class is coffe which is decorated with milk which is decorated with sugar (using the example in Head first design patterns) milk would be an intermediate decorator as it decorates the base coffee, and is decorated by the sugar. Yet More Clarification :) The idea is that items change stats, I'd agree that I am shoehorning the decorator into this. I'll look into the state bag. essentially I want a single point of call for the statistics and for them to go up/down when items are equiped/unequiped. I could just apply the modifiers to the characters stats on equiping and roll them back when unequiping. Or whenever a stat is asked for iterate through all the items and calculate the stat. I'm just looking for feedback here, I'm aware that I might be using a chainsaw where scissors would be more appropriate...

  • QT: I've inherited from QTreeView. I've inherited from QStandardItem. How do i Style the items?

    - by San Jacinto
    My Google skills must be failing me today. I've inherited from QTreeView to create a TreeView that stores a QStandardItemModel instead of a QAbstractItemModel. I have also inherited from QStandardItem to create a class to store my data in an item as is necessary. I've successfully inserted my derived QStandardItem into my derived QTreeView's QStandardItemModel. Now the trouble is, I can't figure out how to style it. I know that QTreeView has a setStyleSheet(QString) member, but I can't seem to get it working. It may be as simple as I'm not styling the correct attribute. Any pointers would be appreciated. Thanks. For clarity, here are my class defs. class SurveyTreeItem : public QStandardItem { public: SurveyTreeItem(); SurveyTreeItem( const QString & text ); ~SurveyTreeItem(); }; class StandardItemModelTreeView : public QTreeView { public: StandardItemModelTreeView(QWidget* parent = 0); ~StandardItemModelTreeView(); QStandardItemModel* getStandardItemModel(); }; I've tried the following StyleSheets: StandardTreeView::Item { font: 87 12pt 'Arial Black'; } StandardTreeView::QStandardItem { font: 87 12pt 'Arial Black'; } QTreeView::QStandardItem { font: 87 12pt 'Arial Black'; } QTreeView::Item { font: 87 12pt 'Arial Black'; } QTreeView::SurveyTreeItem { font: 87 12pt 'Arial Black'; } StandardTreeView::SurveyTreeItem { font: 87 12pt 'Arial Black'; }

  • Optimising RSS parsing on App Engine to avoid high CPU warnings

    - by Danny Tuppeny
    I'm pulling some RSS feeds into a datastore in App Engine to serve up to an iPhone app. I use cron to schedule updating the RSS every x minutes. Each task only parses one RSS feed (which has 15-20 items). I frequently get warnings about high CPU usage in the App Engine dashboard, so I'm looking for ways to optimise my code. Currently, I use minidom (since it's already there on App Engine), but I suspect it's not very efficient! Here's the code: dom = minidom.parseString(urlfetch.fetch(url).content) if dom: items = [] for node in dom.getElementsByTagName('item'): item = RssItem( key_name = self.getText(node.getElementsByTagName('guid')[0].childNodes), title = self.getText(node.getElementsByTagName('title')[0].childNodes), description = self.getText(node.getElementsByTagName('description')[0].childNodes), modified = datetime.now(), link = self.getText(node.getElementsByTagName('link')[0].childNodes), categories = [self.getText(category.childNodes) for category in node.getElementsByTagName('category')] ); items.append(item); db.put(items); def getText(self, nodelist): rc = '' for node in nodelist: if node.nodeType == node.TEXT_NODE: rc = rc + node.data return rc There isn't much going on, but the scripts often take 2-6 seconds CPU time, which seems a bit excessive for looping through 20ish items and reading a few attributes. What can I do to make this faster? Is there anything particularly bad in the above code, or should I change to another way of parsing? Are there are any libraries (that work on App Engine) that would be better, or would I be better parsing the RSS myself?

  • Nesting, grouping Sqlite syntax?

    - by Linda
    I can't for the life of me figure out this Sqlite syntax. Our database contains records like: TX, Austin OH, Columbus OH, Columbus TX, Austin OH, Cleveland OH, Dayton OH, Columbus TX, Dallas TX, Houston TX, Austin (State-field and a city-field.) I need output like this: OH: Columbus, Cleveland, Dayton TX: Dallas, Houston, Austin (Each state listed once... and all the cities in that state.) What would the SELECT statement(s) look like?

  • How to implement Master-Detail with Multi-Selection in WPF?

    - by gehho
    Hi, I plan to create a typical Master-Detail scenario, i.e. a collection of items displayed in a ListView via DataBinding to an ICollectionView, and details about the selected item in a separate group of controls (TextBoxes, NumUpDowns...). No problem so far, actually I have already implemented a pretty similar scenario in an older project. However, it should be possible to select multiple items in the ListView and get the appropriate shared values displayed in the detail view. This means, if all selected items have the same value for a property, this value should be displayed in the detail view. If they do not share the same value, the corresponding control should provide some visual clue for the user indicating this, and no value should be displayed (or an "undefined" state in a CheckBox for example). Now, if the user edits the value, this change should be applied to all selected items. Further requirements are: MVVM compatibility (i.e. not too much code-behind) Extendability (new properties/types can be added later on) Does anyone have experience with such a scenario? Actually, I think this should be a very common scenario. However, I could not find any details on that topic anywhere. Thanks! gehho. PS: In the older project mentioned above, I had a solution using a subclass of the ViewModel which handles the special case of multi-selection. It checked all selected items for equality and returned the appropriate values. However, this approach had some drawbacks and somehow seemed like a hack because (besides other smelly things) it was necessary to break the synchronization between the ListView and the detail view and handle it manually.

  • The finest way to store the HardCore Data i android

    - by david
    Hi All! I am working on an application where I have a long listing of different states approximately 20 states and each state consisting of several zones in addition to the weather forcast of each zone eventually. Now the thing is that I have already created the Listing of hardcore data in a list view of all the states. Again I need to add the hardcore data of several zones for each state(min 4 to 5 zones/ state). So , now I am wondering that whether I have to create the separate classes with hardcore names of all the zones in each state or is there any easy way out for doing the same. It would be great if anyone having the idea can tell me. Thanks, david

  • How to use IObservable/IObserver with ConcurrentQueue or ConcurrentStack

    - by James Black
    I realized that when I am trying to process items in a concurrent queue using multiple threads while multiple threads can be putting items into it, the ideal solution would be to use the Reactive Extensions with the Concurrent data structures. My original question is at: http://stackoverflow.com/questions/2997797/while-using-concurrentqueue-trying-to-dequeue-while-looping-through-in-parallel/ So I am curious if there is any way to have a LINQ (or PLINQ) query that will continuously be dequeueing as items are put into it. I am trying to get this to work in a way where I can have n number of producers pushing into the queue and a limited number of threads to process, so I don't overload the database. If I could use Rx framework then I expect that I could just start it, and if 100 items are placed in within 100ms, then the 20 threads that are part of the PLINQ query would just process through the queue. There are three technologies I am trying to work together: Rx Framework (Reactive LINQ) PLING System.Collections.Concurrent structures

  • Custom UITableviewcell shows "fatal error: Can't unwrap Optional.None" issue in swift

    - by user1656286
    I need to load a custom cell in a UITableView. I created a custom subclass of UITableViewCell named "CustomTableViewCell". I have added a UITabelViewCell to the tableview (using drag and drop) as shown in figure. Then in file inspector I set the class of that UITabelViewCell to be "CustomTableViewCell". Here is my code: class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource { @IBOutlet var tableView : UITableView var items = String[]() override func viewDidLoad() { super.viewDidLoad() items = ["Hi","Hello","How"] self.tableView.registerClass(CustomTableViewCell.self, forCellReuseIdentifier: "CusTomCell") // Do any additional setup after loading the view, typically from a nib. } func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int{ return items.count } func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!{ var cell:CustomTableViewCell = self.tableView.dequeueReusableCellWithIdentifier("CusTomCell") as CustomTableViewCell cell.labelTitle.text = items[indexPath.row] return cell; } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } } When I run my code, I get the following error: "fatal error: Can't unwrap Optional.None" as seen in the image.
