• Implementing a post-notification function to perform custom validation

  - by Alejandro Sosa

  Introduction Oracle Workflow Notification System can be extended to perform extra validation or processing via PLSQL procedures when the notification is being responded to. These PLSQL procedures are called post-notification functions since they are executed after a notification action such as Approve, Reject, Reassign or Request Information is performed. The standard signature for the post-notification function is     procedure <procedure_name> (itemtype  in varchar2,                                itemkey   in varchar2,                                actid     in varchar2,                                funcmode  in varchar2,                                resultout in out nocopy varchar2); Modes The post-notification function provides the parameter 'funcmode' which will have the following values: 'RESPOND', 'VALIDATE, and 'RUN' for a notification is responded to (Approve, Reject, etc) 'FORWARD' for a notification being forwarded to another user 'TRANSFER' for a notification being transferred to another user 'QUESTION' for a request of more information from one user to another 'QUESTION' for a response to a request of more information 'TIMEOUT' for a timed-out notification 'CANCEL' when the notification is being re-executed in a loop. Context Variables Oracle Workflow provides different context information that corresponds to the current notification being acted upon to the post-notification function. WF_ENGINE.context_nid - The notification ID  WF_ENGINE.context_new_role - The new role to which the action on the notification is directed WF_ENGINE.context_user_comment - Comments appended to the notification   WF_ENGINE.context_user - The user who is responsible for taking the action that updated the notification's state WF_ENGINE.context_recipient_role - The role currently designated as the recipient of the notification. This value may be the same as the value of WF_ENGINE.context_user variable, or it may be a group role of which the context user is a member. WF_ENGINE.context_original_recipient - The role that has ownership of and responsibility for the notification. This value may differ from the value of the WF_ENGINE.context_recipient_role variable if the notification has previously been reassigned.  Example Let us assume there is an EBS transaction that can only be approved by a certain people thus any attempt to transfer or delegate such notification should be allowed only to users SPIERSON or CBAKER. The way to implement this functionality would be as follows: Edit the corresponding workflow definition in Workflow Builder and open the notification. In the Function Name enter the name of the procedure where the custom code is handled, for instance, TEST_PACKAGE.Post_Notification In PLSQL create the corresponding package TEST_PACKAGE with a procedure named Post_Notification, as follows:     procedure Post_Notification (itemtype  in varchar2,                                  itemkey   in varchar2,                                  actid     in varchar2,                                  funcmode  in varchar2,                                  resultout in out nocopy varchar2) is     l_count number;     begin       if funcmode in ('TRANSFER','FORWARD') then         select count(1) into l_count         from WF_ROLES         where WF_ENGINE.context_new_role in ('SPIERSON','CBAKER');               --and/or any other conditions         if l_count<1 then           WF_CORE.TOKEN('ROLE', WF_ENGINE.context_new_role);           WF_CORE.RAISE('WFNTF_TRANSFER_FAIL');         end if;       end if;     end Post_Notification; Launch the workflow process with the changed notification and attempt to reassign or transfer it. When trying to reassign the notification to user CBROWN the screen would like like below: Check the Workflow API Reference Guide, section Post-Notification Functions, to see all the standard, seeded WF_ENGINE variables available for extending notifications processing.

• Stage3D: Camera pans the whole screen

  - by Thomas Versteeg

  I am trying to create a 2D Stage3D game where you can move the camera around the level in an RTS style. I thought about using Orthographic Matrix3D functions for this but when I try to scroll the whole "stage" also scrolls. This is the Camera code: public function Camera2D(width:int, height:int, zoom:Number = 1) { resize(width, height); _zoom = zoom; } public function resize(width:Number, height:Number):void { _width = width; _height = height; _projectionMatrix = makeMatrix(0, width, 0, height); _recalculate = true; } protected function makeMatrix(left:Number, right:Number, top:Number, bottom:Number, zNear:Number = 0, zFar:Number = 1):Matrix3D { return new Matrix3D(Vector.<Number>([ 2 / (right - left), 0, 0, 0, 0, 2 / (top - bottom), 0, 0, 0, 0, 1 / (zFar - zNear), 0, 0, 0, zNear / (zNear - zFar), 1 ])); } public function get viewMatrix():Matrix3D { if (_recalculate) { _recalculate = false; _viewMatrix.identity(); _viewMatrix.appendTranslation( -_width / 2 - _x, -_height / 2 - y, 0); _viewMatrix.appendScale(_zoom, _zoom, 1); _renderMatrix.identity(); _renderMatrix.append(_viewMatrix); _renderMatrix.append(_projectionMatrix); } return _renderMatrix; } And the camera is send directly to the GPU with: c3d.setProgramConstantsFromMatrix(Context3DProgramType.VERTEX, 0, cameraMatrix, true); And these are the shaders: ------Vertex Shader------ m44 op, va0, vc0 mov v0, va1.xy mov v0.z, va0.z ------Fragment Shader------ tex ft0, v0, fs0 <2d,linear,nomip> mov oc, ft1 Here is a example and here are two screenshots to show what I mean: How do I only let the inside of the stage3D scroll and not the whole stage?

• Handling Errors In PHP When Using MVC

  - by James Jeffery

  I've been using Codeigniter a lot recently, but one thing that gets on my nerves is handling errors and displaying them to the user. I've never been good at handling errors without it getting messy. My main concern is when returning errors to the user. Is it good practice to use exceptions and throw/catch exceptions rather than returning 0 or 1 from functions and then using if/else to handle the errors. Thus, making it easier to inform the user about the issue. I tend to go away from exceptions. My Java tutor at university some years ago told me "exceptions shouldn't be used in production code it's more for debugging". I get the feeling he was lying. But, an example, I have code that adds a user to a database. During the process more than 1 thing could go wrong, such as a database issue, a duplicate entry, a server issue, etc. When an issue happens during registration the user needs to know about it. What's the best way to handle errors in PHP, keeping in mind that I'm using an MVC framework.

• Entity Object Based on PL/SQL

  - by Manoj Madhusoodanan

  This blog describes how to create a PL/SQL based Entity Object.Oracle application has number of APIs and each API will perform numerous number of tasks.We can create PL/SQL based EO which will directly invoke the PL/SQL stored procedure from the EO. Here I am demonstrating using a standard API FND_USER_PKG.CREATEUSER.This API has x_user_name and x_owner as mandatory parameter.My task is to create a user through OAF page which will accept User Name and Password. Following steps needs to be performed to achieve the above scenario. 1) Create FndUserEO as follows Include all the API parameters and WHO columns in the EO. Make UserName and EncryptedUserPassword ( Here I am not using Encrypted Password. The column name is same as table column so I am keeping the same) column as mandatory. Generate VO. 2) Edit FndUserEOImpl and add the following 3) Attach FndUserVO to AM 4) Create the UI 5) Deploy following files to middle tier and restart the server.  Entity Object: xxcust.oracle.apps.fnd.user.schema.server.FndUserEO.xml xxcust.oracle.apps.fnd.user.schema.server.FndUserEOImpl.java View Object: xxcust.oracle.apps.fnd.user.server.FndUserVO.xml xxcust.oracle.apps.fnd.user.server.FndUserVOImpl.javaUser Interface: xxcust.oracle.apps.fnd.user.webui.CreateFndUserCO.java xxcust.oracle.apps.fnd.user.webui.CreateFndUserPG.xmlYou can test by giving User Name and Password.

• Is this kind of Design by Contract useless?

  - by Charlie Pigarelli

  I've just started informatics university and I'm attending a programming course about C(++). The programming professor prefers to teach very few things (in 3 month we have just reached the functions topic) and connect every topic with a type of programming design that somehow is similar to the Design by Contract design. Basically what he ask us to do is to write every exercise with comments Pre-conditions, Post-conditions and Invariants that should prove the correctness of each program we write. But this doesn't make any sense to me. I mean, ok: maybe writing down your thoughts prevent you from doing some mistakes, but if this is all an abstract thing, then if your program intuition is wrong you'll write your program wrong and then you'll also write pre and post conditions wrong probably auto convincing your self about its correctness. Most of the time, both me and other students have written programs that seemed ok and that had correct pre and post condition too. But at the moment of testing it was just completely wrong. I had some experience before this course of programming and I had written a lot of line of code before and I found myself comfortably with just writing a program and unit test it. It take less time to accomplish and is less "abstract" than just thinking about what every single piece of your program should do in every case (which is kinda like mentally testing it). Finally, all this pre and post conditions takes me like 80% of the total time of the exercise. It's harder to think about putting down this pre and post correct than to write the program itself. Since we are like the only course of the only university probably in the entire world that makes this things, could someone please tell me how should I manage this thing? Am I right thinking that this doesn't worth anything? Should I change university? (there are like double of the people attending that course and it seems that usually very few people passes the exam the first year). Should I convince myself it's method is right?

• Working with data and meta data that are separated on different servers

  - by afuzzyllama

  While developing a product, I've come across a situation where my group wants to store meta data for data entry forms (questions, layout, etc) in a different database then the database where the collected data is stored. This is mostly for security because we want to be able to have our meta data public facing, while keeping collected data as secure as possible. I was thinking about writing a web service that provides the meta information that the data collection program could access. The only issue I see with this approach is the front end is going to have to match the meta data with the collected data, which would be more efficient as a join on the back end. Currently, this system is slated to run on .NET and MSSQL. I haven't played around with .NET libraries running in SQL, but I'm considering trying to create logic that would pull from the web service, convert the meta data into a table that SQL can join on, and return the combined data and meta data that way. Is this solution the wrong way to approach the problem? Is there a pattern or "industry standard" way of bringing together two datasets that don't live in the same database?

• How to refactor while keeping accuracy and redundancy?

  - by jluzwick

  Before I ask this question I will preface it with our environment. My team consists of 3 programmers working on multiple different projects. Due to this, our use of testing is mostly limited to very general black box testing. Take the following assumptions also: Unit Tests will eventually be written but I'm under strict orders to refactor first Ignore common Test-Driven Development techniques when given this environment, my time is limited. I understand that if this were done correctly, our team would actually save money in the long-term by building Unit-Tests before hand. I'm about to refactor a fairly large portion of the code that is critical. While I believe my code will accurately work when done and after our black box testing, I realize that there will be new data that the new code might not be able to handle. What I wanted to know is how to keep old code that functions 98% of the time so that we can call those subroutines in case the new code doesn't work properly. Right now I'm thinking of separating the old code in a separate class file and adding a variable to our config that will tell the program which code to use. Is there a better way to handle this? NOTE: We do use revision control and we have archived builds so the client could always revert to a previous build, but I would like to see if there is a decent way of doing this besides reverting. I want this so they can use the other new functionality delivered in the new build. Edit: While I agree I will need to write Unit Tests for this, I don't believe I will capture everything with them. I'm looking for ways to easily be able to revert to the old, functional code should anything happen. While I know this is a poor practice, I'm planning on removing this code after our team can guarantee that the new code works to the same standards as the old.

• SQL Developer: BLOBs and the External Editor

  - by thatjeffsmith

  We already know how easy it is to view images and plain text with the BLOB editor, yes? But what if I have in my column a bunch of PDFs stored? I want to see that stuff without having to save the file, finding it, and then opening it. Why can’t I just automatically open it directly from the database? Well, it seems you can. Here’s how. External Editors Step 1: Make sure you have the file types and associated editors defined in the preferences. External editors available from the BLOB viewer Based on what’s going on in your OS, you’ll have several of these already defined. If not, it’s pretty simple to add them manually. Now, assuming you’ve got some fun data loaded up, let’s try it out. A PDF As you can see in the screenshot above, PDF is mapped to Adobe Reader. I just happen to have a PDF loaded into a BLOB, let’s send it to the external editor. Click on the hyperlinked text to load the PDF straight to Adobe Here’s it working in action (click on the image to see the animation): If it’s a big file, you will see a dialog where we’re downloading the data. Now if I were to edit said document and save it back to the database via the ‘Load’ mechanism, then we’ve come full circle.

• Column order can matter

  - by Dave Ballantyne

  Ordinarily, column order of a SQL statement does not matter. Select a,b,c from table will produce the same execution plan as   Select c,b,a from table However, sometimes it can make a difference.   Consider this statement (maxdop is used to make a simpler plan and has no impact to the main point):   select SalesOrderID, CustomerID, OrderDate, ROW_NUMBER() over (Partition By CustomerId order by OrderDate asc) as RownAsc, ROW_NUMBER() over (Partition By CustomerId order by OrderDate Desc) as RownDesc from sales.SalesOrderHeader order by CustomerID,OrderDateoption(maxdop 1) If you look at the execution plan, you will see similar to this That is three sorts.  One for RownAsc,  one for RownDesc and the final one for the ‘Order by’ clause.  Sorting is an expensive operation and one that should be avoided if possible.  So with this in mind, it may come as some surprise that the optimizer does not re-order operations to group them together when the incoming data is in a similar (if not exactly the same) sorted sequence.  A simple change to swap the RownAsc and RownDesc columns to produce this statement : select SalesOrderID, CustomerID, OrderDate, ROW_NUMBER() over (Partition By CustomerId order by OrderDate Desc) as RownDesc , ROW_NUMBER() over (Partition By CustomerId order by OrderDate asc) as RownAsc from Sales.SalesOrderHeader order by CustomerID,OrderDateoption(maxdop 1) Will result a different and more efficient query plan with one less sort. The optimizer, although unable to automatically re-order operations, HAS taken advantage of the data ordering if it is as required.  This is well worth taking advantage of if you have different sorting requirements in one statement. Try grouping the functions that require the same order together and save yourself a few extra sorts.

• asp.net mvc vs angular.js model binding

  - by aw04

  So I've noticed a trend lately of .net web developers using angular.js on the client side of applications and I've become more curious as I play around with angular and compare it to how I would do things in asp.net mvc. I'll give a quick example of what really got me thinking. I recently came across a situation at work (I work in a .net environment) where I needed to create a table bound to a collection of objects that had the ability to add and remove rows/items from the collection. I had an add button that created a new object and appended a row to the end of the table, and a remove button in each row to remove a particular object/row. Using asp.net mvc, I first found myself making an ajax call to the server for each operation, updating the server side model, and refreshing part of the page to show the result in the table. This worked but I didn't really like the idea of calling the server to update the model each time, so I tried to come up with a solution to do this on the client side. It turned out to be quite a task, as I had to generate the html on add with validation and all and the correct indexing for the model binding to work. It got worse on remove, as I ended up with a crazy string replace function to recreate the indexes on each item to satisfy the binding requirements (if an item other than the last is removed, the indexes are no longer correct). Now out of curiosity, I tried to recreate this at home in angular (which I had no experience with) and it took me all of about 10 minutes with simple functions to add and remove items from the client side model. This is just one example, but it seems to me that I'm able to achieve the same results with far fewer calls to the server in angular because of the fact that it binds to a client side model. So my question is, is this a distinct advantage of using a javascript mvc framework or am I somehow under utilizing the power of asp.net mvc and am I right in thinking that these operations should be done on the client and have no business requiring calls to the server?

• From physics to Java programmer?

  - by inovaovao

  I'm a physics phd with little actual programming experience. I've always liked programming and played around with Basic and Pascal (also VB and Delphi) as a teen, but the largest actual project I completed was an assignement for the introductory computer science class in university where I wrote a nice little program (about 1500 lines of pascal) to display functions of 2 variables in 3D. I've had also a couple other projects of a few hundred lines range, but during my phd I didn't have (or take) the time to program more (string theory is hard guys!), beside playing around with ruby. Now I've decided that I'm more interested in programming than in physics and started to learn Java (hoping to pass the certification exam next week) and OO design. Still, I have trouble deciding on what to focus next (Java EE? Web development? algorithms and C programming?) in order to maximize my employement chances. Bear in mind that I'm aiming (mostly) at the swedish job market and that I'm 30 years old. So for the questions: Do you think that I have any chances to start and make a career in IT and programming coming from physics? What would be the best strategy to maximize my value in the field? Do you have suggestions as to where my physics background might be useful?

• WoW lua: Getting quest attributes before the QUEST_DETAIL event

  - by Matt DiTrolio

  I'd like to determine the attributes of a quest (i.e., information provided by functions such as QuestIsDaily and IsQuestCompletable) before the player clicks on the quest detail. I'm trying to write an add-on that handles accepting and completing of daily quests with a single click on the NPC, but I'm running into a problem whereby I can't find out anything about a given quest unless the quest text is currently being displayed, defeating the purpose of the add-on. Other add-ons of this nature seem to be getting around this limitation by hard-coding information about quests, an approach I don't much like as it requires constant maintenance. It seems to me that this information must be available somehow, as the game itself can properly figure out which icon to display over the head of the NPC without player interaction. The only question is, are add-on authors allowed access to this information? If so, how? EDIT: What I originally left out was that the situations I'm trying to address are when: An NPC has multiple quests The quest detail is not the first thing that shows up upon right-click Otherwise, the situation is much simpler, as I have the information I need provided immediately.

• Designing configuration for subobjects

  - by Stefano Borini

  I have the following situation: I have a class (let's call it Main) encapsulating a complex process. This class in turn orchestrates a sequence of subalgorithms (AlgoA, AlgoB), each one represented by an individual class. To configure Main, I have a configuration stored into a configuration object MainConfig. This object contains all the config information for AlgoA and AlgoB with their specific parameters. AlgoA has no interest to the information relative to the configuration of AlgoB, so technically I could have (and in practice I have) a contained MainConfig.AlgoAConfig and MainConfig.AlgoBConfig instances, and initialize as AlgoA(MainConfig.AlgoAConfig) and AlgoB(MainConfig.AlgoBConfig). The problem is that there is some common configuration data. One example is the printLevel. I currently have MainConfig.printLevel. I need to propagate this information to both AlgoA and AlgoB, because they have to know how much to print. MainConfig also needs to know how much to print. So the solutions available are I pass the MainConfig to AlgoA and AlgoB. This way, AlgoA has technically access to the whole configuration (even that of AlgoB) and is less self-contained I copy the MainConfig.printLevel into AlgoAConfig and AlgoBConfig, so I basically have three printLevel information repeated. I create a third configuration class PrintingConfig. I have an instance variable MainConfig.printingConfig, and then pass to AlgoA both MainConfig.AlgoAConfig and MainConfig.printingConfig. Have you ever found this situation? How did you solve it ? Which one is stylistically clearer to a new reader of the code ?

• Static classes and/or singletons -- How many does it take to become a code smell?

  - by Earlz

  In my projects I use quite a lot of static classes. These are usually classes that naturally seem to fit into a single-instance type of thing. Many times I use static classes and recently I've started using some singletons. How many of these does it take to become a code smell? For instance, in my recent project which has a lot of static classes is an Authentication library for ASP.Net. I use a static class for a helper class that fixes ASP.Net error codes so it can be used like CustomErrorsFixer.Fix(Context); Or my authentication class itself is a static class //in global.asax's begin_application Authentication.SomeState="blah"; Authentication.SomeOption=true; //etc //in global.asax's begin_request Authentication.Authenticate(); When are static or singleton classes bad to use? Am I doing it wrong, or am I just in a project that by definition has very little per-instance state associated with it? The only per-instance state I have is stored in HttpContext.Current.Items like so: /// <summary> /// The current user logged in for the HTTP request. If there is not a user logged in, this will be null. /// </summary> public static UserData CurrentUser{ get{ return HttpContext.Current.Items["fscauth_currentuser"] as UserData; //use HttpContext.Current as a little place to persist static data for this request } private set{ HttpContext.Current.Items["fscauth_currentuser"]=value; } }

• rkhunter: right way to handle warnings further?

  I googled some and checked out two first links it found: http://www.skullbox.net/rkhunter.php http://www.techerator.com/2011/07/how-to-detect-rootkits-in-linux-with-rkhunter/ They don't mention what shall I do in case of such warnings: Warning: The command '/bin/which' has been replaced by a script: /bin/which: POSIX shell script text executable Warning: The command '/usr/sbin/adduser' has been replaced by a script: /usr/sbin/adduser: a /usr/bin/perl script text executable Warning: The command '/usr/bin/ldd' has been replaced by a script: /usr/bin/ldd: Bourne-Again shell script text executable Warning: The file properties have changed: File: /usr/bin/lynx Current hash: 95e81c36428c9d955e8915a7b551b1ffed2c3f28 Stored hash : a46af7e4154a96d926a0f32790181eabf02c60a4 Q1: Is there more extended HowTos which explain how to deal with different kind warnings? And the second question. Were my actions sufficient to resolve these warnings? a) To find the package which contains the suspicious file, e.g. it is debianutils for the file /bin/which ~ > dpkg -S /bin/which debianutils: /bin/which b) To check the debianutils package checksums: ~ > debsums debianutils /bin/run-parts OK /bin/tempfile OK /bin/which OK /sbin/installkernel OK /usr/bin/savelog OK /usr/sbin/add-shell OK /usr/sbin/remove-shell OK /usr/share/man/man1/which.1.gz OK /usr/share/man/man1/tempfile.1.gz OK /usr/share/man/man8/savelog.8.gz OK /usr/share/man/man8/add-shell.8.gz OK /usr/share/man/man8/remove-shell.8.gz OK /usr/share/man/man8/run-parts.8.gz OK /usr/share/man/man8/installkernel.8.gz OK /usr/share/man/fr/man1/which.1.gz OK /usr/share/man/fr/man1/tempfile.1.gz OK /usr/share/man/fr/man8/remove-shell.8.gz OK /usr/share/man/fr/man8/run-parts.8.gz OK /usr/share/man/fr/man8/savelog.8.gz OK /usr/share/man/fr/man8/add-shell.8.gz OK /usr/share/man/fr/man8/installkernel.8.gz OK /usr/share/doc/debianutils/copyright OK /usr/share/doc/debianutils/changelog.gz OK /usr/share/doc/debianutils/README.shells.gz OK /usr/share/debianutils/shells OK c) To relax about /bin/which as I see OK /bin/which OK d) To put the file /bin/which to /etc/rkhunter.conf as SCRIPTWHITELIST="/bin/which" e) For warnings as for the file /usr/bin/lynx I update checksum with rkhunter --propupd /usr/bin/lynx.cur Q2: Do I resolve such warnings right way?

• Camera field of view: 3D projections & trigonometry

  - by Thomas O

  Okay, here goes. I have a camera at (Xc, Yc, Zc.) The Xc and Yc coordinates are latitude/longitude, and the Zc coordinate is an altitude in metres. I have a point at (Xp, Yp, Zp) and a field of view on the camera (Th1, Th2) - where Th1 is horizontal FOV and Th2 is vertical FOV. Given this information, I'd like to: test if the point is visible (i.e. in the camera's FOV) project the point as the camera would see it I've figured out already that the camera's horizontal view at any given distance is tan(Th1) * distance, but I don't know how to test if the point is visible. Accuracy is not critical. I would prefer a simple solution over a complicated solution, if it works well enough. The computations will be performed by a small microcontroller, which isn't very fast at things like trig functions. P.S. this is not homework, I'm doing this for some game development. It will be integrated with the real world, hence the latitude/longitude/altitude. It involves flying real RC planes through virtual hoops (or chasing virtual targets), so I have to project the positions of these hoops on a display.

• BizTalk 2009 - The Community ODBC Adapter: Receive Location

  - by Stuart Brierley

  I have previously talked about the installation of the Community ODBC adapter and also using the ODBC adapter to generate schemas.  But what about creating a receive location? An ODBC receive location will periodically poll the configured database using the stored procedure or SQL string defined in your request schema. If you need to, begin by adding a new receive port to your BizTalk configuration. Create a new receive location and select to use the ODBC adapter and click Address. You will now be shown the ODBC Community Adapter Transport properties window.  Select connection string and you will be shown the Choose data Source window.  If you have already created the Test Database source when generating a schema from ODBC this will be shown (if not go and take a look in my previous post to see how this is done).   You will then need to choose the SQL command that will be run by the recieve port.  In this case I have deployed the Test Mapping schemas that I created previously and selected the Request schema. You should now have populated the appropriate properties for the ODBC Com Adapter. Finally set the standard receive location properties and your ODBC receive location is now ready.

• DNS records on website.. What are they for?

  - by Blake Nic

  Recently we had to get some ddos protection for our website because of the large attacks we were seeing after getting a bit of popularity. We handed over our domain and hosting information to our ddos protection provider. It worked perfectly but I have a question. On our DNS records we have the Host and Answer and Type. The Host has our domain name there. The answer is this: SOMETEXTXXXX.dv.googlehosted.com. And when i copy and paste it into my browser it gives me a 404 error. But our website still loads and functions as it should. I don't understand why it would need this? I asked them about this and they said it is a method for ddos protection and the other IPs are the reverse proxy (the other ips give a 404 error too). Can anyone expand on this more please. How does all this tie in together and make the internet browser know where to point the person with all these reverse proxies and stuff I don't understand. Thank you. Here is an image for reference: http://i.stack.imgur.com/qo5QO.png

• Why doesn't Python have a "flatten" function for lists?

  - by Hubro

  Erlang and Ruby both come with functions for flattening arrays. It seems like such a simple and useful tool to add to a language. One could do this: >>> mess = [[1, [2]], 3, [[[4, 5]], 6]] >>> mess.flatten() [1, 2, 3, 4, 5, 6] Or even: >>> import itertools >>> mess = [[1, [2]], 3, [[[4, 5]], 6]] >>> list(itertools.flatten(mess)) [1, 2, 3, 4, 5, 6] Instead, in Python, one has to go through the trouble of writing a function for flattening arrays from scratch. This seems silly to me, flattening arrays is such a common thing to do. It's like having to write a custom function for concatenating two arrays. I have Googled this fruitlessly, so I'm asking here; is there a particular reason why a mature language like Python 3, which comes with a hundred thousand various batteries included, doesn't provide a simple method of flattening arrays? Has the idea of including such a function been discussed and rejected at some point?
