  • Simple alternative to GNU Readline library not GPL

    - by Bo Jensen
    I love the GNU readline library, but since it is under a GPL license, I can not use it for commercial software. Do you know alternatives ? I only need the commandline history and auto completion (of customer keywords and files) features. I found this link : http://github.com/antirez/linenoise which seem to be a good starting point, but does not have auto completion. Any suggestions, surely this must be a common task for people building interactive shell commands.

  • Simple PHP Regex question

    - by Dave Kiss
    Hi all, I'd like to validate a field in a form to make sure it contains the proper formatting for a URL linking to a Vimeo video. Below is what I have in Javascript, but I need to convert this over to PHP (not my forte) Basically, I need to check the field and if it is incorrectly formatted, I need to store an error message as a variable.. if it is correct, i store the variable empty. // Parse the URL var PreviewID = jQuery("#customfields-tf-1-tf").val().match(/http:\/\/(www.vimeo|vimeo)\.com(\/|\/clip:)(\d+)(.*?)/); if ( !PreviewID ) { jQuery("#cleaner").html('<div id="vvqvideopreview"><?php echo $this->js_escape( __("Unable to parse preview URL. Please make sure it's the <strong>full</strong> URL and a valid one at that.", 'vipers-video-quicktags') ); ?></div>'); return; } The traditional vimeo url looks like this: http://www.vimeo.com/10793773 Thanks!

  • PHP Simple modification/correction

    - by Adrian M.
    Hello, I got this code from someone, it's almost perfect to create a dynamic breadcrumb, but there just a little glitch because it echoes two dividers before the breadcrumb: $crumbs = explode("/",$_SERVER["REQUEST_URI"]); foreach($crumbs as $crumb){ echo ucfirst(str_replace(array(".php","_"),array(""," "),'>' . $crumb)); } it echoes: "contentcommonfile" what I want it to look like is "contentcommon1" and also I will deeply appreciate if someone can tell me how can I add links for all the items in the array except the last one (file)? Thank you so much everybody, this website really helped me a lot to learn php by examples!

  • Simple cropping with Paperclip

    - by collimarco
    I would like to crop images on upload using Paperclip to get square thumbs from the center of the original picture. I find out a method in documentation that seems to do exactly what I want: transformation_to(dst, crop = false) The problem is that I can't figure out where to use this method. It would be great to simply pass something as a parameter here: has_attached_file :picture, :styles = { :medium = "600x600", :thumb = "something here" }

  • Save simple data in Magento's DB w/o Model

    - by Joseph Mastey
    I'm looking to save some data in the Magento database without hassling with creating a new EAV object (or even a DB table if I can avoid it). Is there any place that you all know about that Magento will let you store serialized data? If it matters, the data is a serialized set of SKUs that I need to retrieve. I know that I could create a new model, or possibly even create an attribute as a flag on each product, but those are both really overkill for my purposes. Thanks, Joe

I've started with haskell today so please go easy on the explanations.

  • Unable to reverse seemingly simple rails migration - getting "altered_table.column may not be NULL"

    - by brad
    I have a table 'invoices' in my development database (sqlite3) populated with a small amount of test data. I wanted to add a column 'invoice_number' to it and set up a migration like so: class AddInvoiceNumberColumnToInvoices < ActiveRecord::Migration def self.up add_column :invoices, :invoice_number, :integer end def self.down remove_column :invoices, :invoice_number end end I ran rake db:migrate and it seemed to migrate just fine. However, when I tried to access this column through ActiveRecord it didn't seem to be there. I decided to undo this migration and try again (not sure what I was going to try but I thought I'd start by undoing it) with rake db:migrate VERSION='whatever_the_migration_before_this_one_was_called'. This failed with the error message == AddInvoiceNumberColumnToInvoices: reverting =============================== -- remove_column(:invoices, :invoice_number) rake aborted! An error has occurred, this and all later migrations canceled: altered_invoices.invoice_number may not be NULL I can't find any documentation of this error. Is anyone able to explain what I have done wrong, and more importantly how I can fix this?

  • Simple 3x3 matrix inverse code (C++)

    - by batty
    What's the easiest way to compute a 3x3 matrix inverse? I'm just looking for a short code snippet that'll do the trick for non-singular matrices, possibly using Cramer's rule. It doesn't need to be highly optimized. I'd prefer simplicity over speed. I'd rather not link in additional libraries. Primarily I was hoping to have this on Stack Overflow so that I wouldn't have to hunt around for it or rewrite from scratch again next time.

  • A few questions about a Rails model for a simple addressbook app

    - by user284194
    I have a Rails application that lists information about local services. My objectives for this model are as follows: 1. Require the name and tag_list fields. 2. Require one or more of the tollfreephone, phone, phone2, mobile, fax, email or website fields. 3. If the paddress field has a value, then encode it with the Geokit plugin. Here is my entry.rb model: class Entry < ActiveRecord::Base validates_presence_of :name, :tag_list validates_presence_of :tollfreephone or :phone or :phone2 or :mobile or :fax or :email or :website acts_as_taggable_on :tags acts_as_mappable :auto_geocode=>{:field=>:paddress, :error_message=>'Could not geocode physical address'} before_save :geocode_paddress validate :required_info def required_info unless phone or phone2 or tollfreephone or mobile or fax or email or website errors.add_to_base "Please have at least one form of contact information." end end private def geocode_paddress #if paddress_changed? geo=Geokit::Geocoders::MultiGeocoder.geocode (paddress) errors.add(:paddress, "Could not Geocode address") if ! geo.success self.lat, self.lng = geo.lat,geo.lng if geo.success #end end end Requiring name and tag_list work, but requiring one (or more) of the tollfreephone, phone, phone2, mobile, fax, email or website fields does not. As for encoding with Geokit, in order to save a record with the model I have to enter an address. Which is not the behavior I want. I would like it to not require the paddress field, but if the paddress field does have a value, it should encode the geocode. As it stands, it always tries to geocode the incoming entry. The commented out "if paddress_changed?" was not working and I could not find something like "if paddress_exists?" that would work. Help with any of these issues would be greatly appreciated. I posted three questions pertaining to my model because I'm not sure if they are preventing each other from working. Thank you for reading my questions.

  • Ruby: what is the pitfall in this simple code excerpt that tests variable existence

    - by zipizap
    I'm starting with Ruby, and while making some test samples, I've stumbled against an error in the code that I don't understand why it happens. The code pretends to tests if a variable finn is defined?() and if it is defined, then it increments it. If it isn't defined, then it will define it with value 0 (zero). As the code threw an error, I started to decompose it in small pieces and run it, to better trace where the error was comming from. The code was run in IRB irb 0.9.5(05/04/13), using ruby 1.9.1p378 First I certify that the variable finn is not yet defined, and all is ok: ?> finn NameError: undefined local variable or method `finn' for main:Object from (irb):134 from /home/paulo/.rvm/rubies/ruby-1.9.1-p378/bin/irb:15:in `<main>' >> Then I certify that the following inline-condition executes as expected, and all is ok: ?> ((defined?(finn)) ? (finn+1):(0)) => 0 And now comes the code that throws the error: ?> finn=((defined?(finn)) ? (finn+1):(0)) NoMethodError: undefined method `+' for nil:NilClass from (irb):143 from /home/paulo/.rvm/rubies/ruby-1.9.1-p378/bin/irb:15:in `<main>' I was expecting that the code would not throw any error, and that after executing the variable finn would be defined with a first value of 0 (zero). But instead, the code thows the error, and finn get defined but with a value of nil. >> finn => nil Where might the error come from?!? Why does the inline-condition work alone, but not when used for the finn assignment? Any help apreciated :)

  • My simple program runs on Android emulator, but not on my Nexus One

    - by noisesolo
    To clarify, I have no trouble getting the Nexus One connected in developer's mode. I can actually get Eclipse to "run" my program on my Nexus One. However, my Nexus One simply gets stuck in a reboot loop. I've also created an .apk file and put it onto my Nexus One, installing it with apkInstaller. However, it crashed while installing. I see my app on my phone, but I'm kind of afraid to run it. I am not doing anything fancy in my program; all it does is generate text by shuffling a couple arrays of strings together. It uses a bunch of text views, two buttons, and a spinner. I have only edited the main source file, the strings XML file, and the layout XML file, nothing else. It's a 2.1-update1 program and it runs fine on the emulator. Does anyone have any idea what's going on? I'm using Windows 7 (32 bit) and my Nexus One is running Cyanogen 5.0.7.1. I'm pretty sure it's my code that's causing the problem. Now I'm just wondering if there are any common mistakes that would lead my app to run on the emulator but not on my device. Thanks in advance.

  • Simple MySQL Query taking 45 seconds (Gets a record and its "latest" child record)

    - by Brian Lacy
    I have a query which gets a customer and the latest transaction for that customer. Currently this query takes over 45 seconds for 1000 records. This is especially problematic because the script itself may need to be executed as frequently as once per minute! I believe using subqueries may be the answer, but I've had trouble constructing it to actually give me the results I need. SELECT customer.CustID, customer.leadid, customer.Email, customer.FirstName, customer.LastName, transaction.*, MAX(transaction.TransDate) AS LastTransDate FROM customer INNER JOIN transaction ON transaction.CustID = customer.CustID WHERE customer.Email = '".$email."' GROUP BY customer.CustID ORDER BY LastTransDate LIMIT 1000 I really need to get this figured out ASAP. Any help would be greatly appreciated!

  • simple Java "service provider frameworks"?

    - by Jason S
    I refer to "service provider framework" as discussed in Chapter 2 of Effective Java, which seems like exactly the right way to handle a problem I am having, where I need to instantiate one of several classes at runtime, based on a String to select which service, and an Configuration object (essentially an XML snippet): But how do I get the individual service providers (e.g. a bunch of default providers + some custom providers) to register themselves? interface FooAlgorithm { /* methods particular to this class of algorithms */ } interface FooAlgorithmProvider { public FooAlgorithm getAlgorithm(Configuration c); } class FooAlgorithmRegistry { private FooAlgorithmRegistry() {} static private final Map<String, FooAlgorithmProvider> directory = new HashMap<String, FooAlgorithmProvider>(); static public FooAlgorithmProvider getProvider(String name) { return directory.get(serviceName); } static public boolean registerProvider(String name, FooAlgorithmProvider provider) { if (directory.containsKey(name)) return false; directory.put(name, provider); return true; } } e.g. if I write custom classes MyFooAlgorithm and MyFooAlgorithmProvider to implement FooAlgorithm, and I distribute them in a jar, is there any way to get registerProvider to be called automatically, or will my client programs that use the algorithm have to explicitly call FooAlgorithmRegistry.registerProvider() for each class they want to use?
