• Get information about a function in python, looking at source code

  - by Werner

  Hi, the following code comes from the matplotlib gallery: #!/usr/bin/env python from pylab import * x = array([10, 8, 13, 9, 11, 14, 6, 4, 12, 7, 5]) y = array([8.04, 6.95, 7.58, 8.81, 8.33, 9.96, 7.24, 4.26, 10.84, 4.82, 5.68]) I am new to python, and would like to change the content of x and y from an input file. I have two short questions: I could guess what array means, but once I see it on the code, how can I know to which library it belongs and more information about it? Should I use some kind of python debug commands? How do I insert the content of my input file into x? Thanks

• How can this code be made more Pythonic?

  - by usethedeathstar

  This next part of code does exactly what I want it to do. dem_rows and dem_cols contain float values for a number of things i can identify in an image, but i need to get the nearest pixel for each of them, and than to make sure I only get the unique points, and no duplicates. The problem is that this code is ugly and as far as I get it, as unpythonic as it gets. If there would be a pure-numpy-solution (without for-loops) that would be even better. # next part is to make sure that we get the rounding done correctly, and than to get the integer part out of it # without the annoying floatingpoint-error, and without duplicates fielddic={} for i in range(len(dem_rows)): # here comes the ugly part: abusing the fact that i overwrite dictionary keys if I get duplicates fielddic[int(round(dem_rows[i]) + 0.1), int(round(dem_cols[i]) + 0.1)] = None # also very ugly: to make two arrays of integers out of the first and second part of the keys field_rows = numpy.zeros((len(fielddic.keys())), int) field_cols = numpy.zeros((len(fielddic.keys())), int) for i, (r, c) in enumerate(fielddic.keys()): field_rows[i] = r field_cols[i] = c

• how to structure code that uses std::rel_ops

  - by R Samuel Klatchko

  I was working on some code and wanted to make use of std::rel_ops. From what I can tell, you need to do using std::rel_ops to your source code to make use of them. But I'm not sure where the best place to put that is. Let's say I have a header file with a class that only defines the minimal operator== and operator<: // foo.h class foo { public: bool operator==(const foo &other) const; bool operator<(const foo &other) const; }; I'm not sure where to put using std::rel_ops. If I leave it out of the foo.h, then every user of foo.h needs to know the implementation detail that foo is not defining all the operators itself. But putting using std::rel_ops inside foo.h breaks the rule of thumb about not having a using in a header file. How do other people resolve this issue?

• Are there any lint tools for C and C++ that check formatting?

  - by Nathan Fellman

  I have a codebase that is touched by many people. While most people make an effort to keep the code nicely formatted (e.g. consistent indentation and use of braces), some don't, and even those that do can't always do it because we all use different editors, so settings like spaces vs. tabs are different. Is there any standard lint tool that checks that code is properly formatted, but doesn't actually change it (like indent but that returns only errors and warnings)? While this question could be answered generally, my focus is on C and C++, because that's what this project is written in.

• How to bundle shell script and C code?

  - by eSKay

  I have a C shell script that calls two C programs - one after the another with some file handling before, in-between and afterwards. Now, as such I have three different files - one C shell script and 2 .c files. I need to give this script to other users. The problem is that I have to distribute three files - which the users must keep in the same folder and then execute the script. Is there some better way to do this? [I know I can make one C code file out of those two... but I will still be left with a shell script and a C code. Actually, the two C codes do entirely different things... so I want them to be separate]

• How do I generate (ActionSctipt) classes for a new project?

  - by Iain

  Whenever I start a new game, I make a whole bunch of classes that extend my base classes, so: com.blah.Game extends com.iainlobb.Game and has some setup code com.blah.Player extends com.iainlobb.Player, and has some setup code etc Now all I need is a way to generate these classes at the start of the project so I don't have to create each one manually. It will save me at least an hour of faffing around per game. So how do I do it? I normally use FlashDevelop but I also have FlexBuilder 3, or I'm happy to download whatever other software I need (PC). Thanks.

• PHP code in drupal pages treating > as ?>

  - by AmaDaden

  While working on an existing Drupal site I've noticed a strange glitch that causes any PHP operator with in it to act like a ? tag. This is happening in in Drupal pages that I create that have a 'Input Format' of 'PHP code'. For example this line of code foreach($array as $key = $value){ results in a very broken page that prints out $value){ Does any one know what could be causing this? My Dev environment is XAMPP. Drupal version is 6.15. PHP version is 5.2.9.

• Is my code really not unit-testable?

  - by John

  A lot of code in a current project is directly related to displaying things using a 3rd-party 3D rendering engine. As such, it's easy to say "this is a special case, you can't unit test it". But I wonder if this is a valid excuse... it's easy to think "I am special" but rarely actually the case. Are there types of code which are genuinely not suited for unit-testing? By suitable, I mean "without it taking longer to figure out how to write the test than is worth the effort"... dealing with a ton of 3D math/rendering it could take a lot of work to prove the output of a function is correct compared with just looking at the rendered graphics.

• Non-object when adding code into html

  - by Luke

  Hello. I am getting the following error: Fatal error: Call to a member function error() on a non-object in /home/gamepla3/public_html/football/result.php on line 177 The line for this is <?php echo $form->error("homescore"); ?> I'm failing to see how this could be the case? The thing worked fine before I added working code into my html document so it looked better. Now I can't get it working?? EDIT. When the code is not within HTML, it works fine. Once I have it within the HTML, it throws back an error? Has anyone seen anything like this before?

• How To Refactor If-else Code Segment?

  - by LostInLib

  I'm developing win8(metro style) application with Html5-js-jquery. I have this code segment; GetBoutiqueDetail: function (boutiqueId, options) { if (IsUserLogin()) { //different job A } else { ShowLoginPanel(undefined); } }, GetProductDetail: function (boutiqueId, productId, options) { if (IsUserLogin()) { //different job B } else { ShowLoginPanel(undefined); } }, AddBasket: function (productId, productVariantId, quantity, options) { if (IsUserLogin()) { //different job C } else { ShowLoginPanel(undefined); } },.... .And ~20 functions should check if user login or not. I should call functions like similar to "Library.GetBoutiqueDetail();" So my question is simple, how can I refactor that code to remove these if-else sections ?

  I am using two content types - test_parent & test_child In test_child there are two fields, both of type datetime And in test_parent there are two fields, week_no & 7 node references I am using node_save to save a new node.

• Internet Explore works very slowly executing JS code

  - by Sergey Basharov

  There is a page that uses PHP to fetch search results from Google Search API and then it puts the results on the page some funny way in a circle. Code and may look crappy but seems that it works more or less fine in Firefox. When you enter a search query and click submit button or Next/Previous links, it fills the wheel with results. The problem is its work in IE. It works there very slowly and then it doesn't clear the wheel before filling in new data, but puts it over that. My friend asked me to help him with this code. Please give me a piece of advice how I can fix it. Thanks so much!

• How to change code settings in eclipse

  - by Maven

  Sorry if the question title is confusing. Let me explain further. I am building a Java project with Eclipse. In my Java product I have conditionals that determine what code is included in the product and relies on static final constants for dead stripping. class BuildFlags { public static final boolean SOME_FLAG = true; // Need to set this programmatically } class SomeOtherClass { public void someMethod() { if (BuildFlags.SOME_FLAG) { // flag specific code } } } My question is how can I change BuildFlags.SOME_FLAG (above) so that I can run a special build without changing the source? Is there some way I can pass flags to the jvm (from eclipse) which I can then access to set this flag programatically?

• Using Linux C code and header files to compile a Windows DLL

  - by df382

  I would like to know if in general it is possible to create a C++ DLL with Visual C++ 2010 starting from C code and the header files I find in a Linux distribution. Theoretically, if I take a piece of C code (that includes different header files) from Linux and I find in the Linux file system all the header files needed for the linkage of the project, will I be able to successfully compile the project in Windows with Visual C++ 2010? Are there some examples or a tutorial for doing this? After compiling a DLL, I would like to use it in a C# application, which I will run under Linux with Mono.

• switch statement with returns -- code correctness

  - by houbysoft

  Hi, let's say I have code in C with approximately this structure: switch (something) { case 0: return "blah"; break; case 1: case 4: return "foo"; break; case 2: case 3: return "bar"; break; default: return "foobar"; break; } Now obviously, the "break"s are not necessary for the code to run correctly, but it sort of looks like bad practice if I don't put them there to me. What do you think? Is it fine to remove them? Or would you keep them for increased "correctness"?

  i want to know that in a c++ code during execution how iostream file is founded. we write #include in c++ program and i know about #include which is a preprocessor directive to load files and is a file name but i don't know that how that file is located. i have some questions in my mind... Is Standard library present in compiler which we are using? Is that file is present in standard library or in our computer? Can we give directory path to locate the file through c++ code if yes then how?

• How to flush coverage data when my test cause app crash - For ios app

  - by Ypy

  I want to get the code coverage of my tests. So I set the settings, build an app with .gcno files and run it on simulator. It can get the coverage data successfully if there is no crash issue. But if the app crashed, I will get nothing. So how can I get the code coverage data when the app crash? In my thought, this is because it will not call __gcov_flush() method when app crash. I only add app does not run in background to my plist file, so __gcov_flush() is called only at the time I press Home button. Is there any way to call __gcov_flush() before the app crash?

• An old flaw in X Window System. How does it work?

  - by Legend

  I was going through an article today when it mentioned the following: "We've found many errors over the years. One of the absolute best was the following in the X Window System: if(getuid() != 0 && geteuid == 0) { ErrorF("Only root"); exit(1); } It allowed any local user to get root access. (The tautological check geteuid == 0 was intended to be geteuid() == 0. In its current form, it compress the address of geteuid to 0; given that the function exists, its address is never 0)." The article explained what was wrong with the code but I would like to know what it means to say that "It allowed any local user to get root access". I am not an expert in C but can someone give me an exact context in which this exploit would work? Specifically, what I mean is, lets say I am the local user, how would I get root access if we assume this code to be present somewhere?

• Extracting methods body from a class of Java Source Code

  - by Muhammad Asaduzzaman

  Hi, I want to extract method body from a Java Source Code. Suppose I have the following code: public class A{ public void print(){ System.out.println("Print This thing"); System.out.println("Print This thing"); System.out.println("Print This thing"); } } My objective is not to extract the method name (in this case print) but also the bode of the method(In this case the three print statement inside the print method). Can anyone suggest how can I do so? Is their any library available for doing so.

• VB6 debugging- doesn't go to error handling code.

  - by Can Ho

  Hi, I'm maintaining a vb6 project(ActiveX DLL). When debugging, the app run into the following function: Public Function HasValue(ByVal vValue) As Boolean On Error GoTo Err If IsMissing(vValue) Then HasValue = False ElseIf IsNull(vValue) Or Len(vValue) = 0 Then HasValue = False ElseIf isEmpty(vValue) Then HasValue = False Else HasValue = True End If Exit Function Err: If IsArray(vValue) Or IsObject(vValue) Then HasValue = True Else HasValue = False End If End Function and it stops at the line ElseIf IsNull(vValue) Or Len(vValue) = 0 Then vValue is a custom object, contains some properties(obviously, not null). Although I didn't put any break point there, the app stopped there and alerted error dialog saying that "Run-time error '438': Object doesn't support this property or method". We had error handling code but the app didn't run to error handling code. It just stopped at the line causing the error and I had to stop the application. Do you have any idea about that? Thank you very much.

  import os path = '/Users/Marjan/Documents/Nothing/Costco' print path names = os.listdir(path) print len(names) for name in names: print name Here is the code I've been using, it lists all the names in this category in terminal. There are a few filenames in this file (Costco) that don't have .html and _files. I need to pick them out, the only issue is that it has over 2,500 filenames. Need help on a code that will search through this path and pick out all the filenames that don't end with .html or _files. Thanks guys
