  • How to integrate pep8.py in Eclipse?

    - by DZPM
    A little background: PEP 8 is the Style Guide for Python Code. It contains the conventions all python programmers should follow. pep8.py is a (very useful) script that checks the code formating of a given python script, according to PEP 8. Eclipse is a great IDE. With the Pydev extension, it that can be used to develop Python I run pep8.py manually when I'm scripting, but with bigger projects I prefer to use Eclipse. It would be really useful to integrate pep8.py in Eclipse/Pydev, so it can be run automatically in all the files in the project, and point to the lines containing the warnings. Maybe there is an obvious way to do it, but I haven't found it yet. Question is: How to integrate pep8.py in Eclipse?

  • What language has the longest "Hello world" program?

    - by Kip
    In most scripting languages, a "Hello world!" application is very short: print "Hello world" In C++, it is a little more complicated, requiring at least 46 non-whitespace characters: #include <cstdio> int main() { puts("Hello world"); } Java, at 75 non-whitespace characters, is even more verbose: class A { public static void main(String[] args) { System.out.print("Hello world"); } } Are there any languages that require even more non-whitespace characters than Java? Which language requires the most? Notes: I'm asking about the length of the shortest possible "hello world" application in a given language. A newline after "Hello world" is not required. I'm not counting whitespace, but I know there is some language that uses only whitespace characters. If you use that one you can count the whitespace characters.

  • Helper Casting Functions -- Is it a code smell?

    - by Earlz
    I recently began to start using functions to make casting easier on my fingers for one instance I had something like this ((Dictionary<string,string>)value).Add(foo); and converted it to a tiny little helper function so I can do this ToDictionary(value).Add(foo); Is this a code smell? Also, what about simpler examples? For example in my scripting engine I've considered making things like this ((StringVariable)arg).Value="foo"; be ToStringVar(arg).Value="foo"; I really just dislike how inorder to cast a value and instantly get a property from it you must enclose it in double parentheses. I have a feeling the last one is much worse than the first one though (also I've marked this language agnostic even though my example is C#)

  • Tools to test softwares against any attacks for programmers ?

    - by berkay
    in these days, i'm interested in software security. As i'm reading papers i see that there are many attacks and researchers are trying to invent new methods for softwares to get more secure systems. this question can be a general including all types of attacks.There are many experienced programmers in SO, i just want to learn what are using to check your code against these attacks ? Is there any tools you use or you don't care ? For example i heard about,static,dynamic code analysis, fuzz testing. SQL injection attacks Cross Site Scripting Bufferoverflow attacks Logic errors Any kind of Malwares Covert Channels ... ... thanks

  • newbie: how to upload images from a form with PHP and mySQL

    - by paracaudex
    I'm creating a web app (locally, so security doesn't matter) in PHP where the user uploads a set of information and a small .jpeg, which is then inserted into a mySQL table. I can do this no problem with all the text data, but I'm not sure how to cause the image to upload alongside it. I assume I will have to use the blob data type and input type="file", but I fooled around with that a little bit and the solution doesn't seem to be an intuitive extension of how input type="text" works. Do I need to do a lot more PHP scripting to get this to work? Is it possible to upload an image with a form, or is there a necessary intermediate step?

  • Why is J2ee/EJBs a dying Trend?

    - by Taranfx
    I might be wrong on this, but I no longer see heavy Business and Web services being hosted using J2ee technologies (Especially EJBs). Having known the power and scalability of J2ee applications, what is keeping developers/decision makers to restrict themselves to Core Java (POJOs) or even other web technologies like PHP, python. Is it the development time? Is it the Ease of configuration? (I feel this should not be a strong reason with Java EE 6, things are simplified) Of course scripting languages are faster to develop, we cannot ignore the fact that they are inherently not-as-scalable as Java Applications are (using App servers)

  • When will NAnt reach version 1.0

    - by sundar venugopal
    I like Nant very much. I do a lot of scripting with NAnt. It is a great little tool. Since NAnt is pre 1.0, when problems occur, I often think if that it is a problem with NAnt itself, but this is not always the case. One funny example: After running the oracle scripts I parsed the log output to make sure there was no problem. I was testing this with a small log file and it was fine. I used the task to load the file contents to a string property and used a regex to search for errors. When I used this script for a large log file, I stopped getting the "build failed" message at the bottom, because I was printing the error messages. Because the "build failed" was hiding at the top, I thought NAnt crashed, but it worked fine. It would be better for NAnt to have a 1.0 release. Any reasons why not?

  • Which hosting will let me execute my own EXE with PHP?

    - by guitar-
    I have a task that PHP (or any server-side scripting language) isn't practical for. It involves a lot of file I/O, processing, etc. and it will execute a lot faster using the program I made in C instead of PHP. Do any hosts allow you to upload your own EXE files and run them on the server using PHP's exec, shell_exec, etc. functions? Do you need a dedicated server to do this? Also, I don't know if Facebook's PHP HipHop is out yet, but I really don't want to use that.

  • How can I put all twill commands together into one piece of code in a .py file?

    - by brilliant
    Hello everybody! I have just started exploring TWILL. Twill is an amazing scripting language for Web browsing and it does all I want!!! So far I've been using twill from a Python shell (IDLE (Python GUI) to be precise) and I do things in the way of executing commands one by one (I mean, I type one command, run it, then type the next command): But I don't know how to put all these commands together in one .py file, so that they would all be executed one by one automatically. It seems that there is such possibility in twill. This example from the twill documentation page (you can see it HERE) shows us one piece of code consisting of several commands: So, my question is: How can I put all commands together in twill?

  • Programmer's editor or IDE for C code

    - by Yktula
    I feel like this question has been repeated here, but I couldn't find it. What open-source programmer's editor or IDE is best for writing code in C? A GUI and integration with Clang for static code analysis or git for version control would be convenient, but aren't necessary. I would ideally use two editors: one feature-filled IDE and one with a small memory footprint, but editors like jEdit, Geany, Diakonos, nano, etc. don't satisfy many of my needs, which include: Good support for refactoring and code completion. Extensibility in C or a "modern" scripting language (i.e. Ruby or Python) Relatively good performance and lack of bloated-ness

  • How prevalent is the use of Emacs' eshell in multi-platform development?

    - by pajato0
    I've only recently become aware of Emacs' eshell tool. It looks quite powerful in that it is entirely written in Emacs Lisp and does not require native subshell support. The Emacs info documentation is a bit sparse but EmacsWiki has pretty decent information, at least on a first glance. Given the potential value of eshell as a scripting tool/programmer's aid that works equally well on multiple platforms I'm wondering how prevalent the use of eshell versus the normal (bash) shell is among software developers. Would those of you who have taken the time to learn it recommend it or is it one of those many interesting ideas that did not really pan out?

  • Writing UTF8 text to file

    - by sonofdelphi
    I am using the following function to save text to a file (on IE-8 w/ActiveX). function saveFile(strFullPath, strContent) { var fso = new ActiveXObject( "Scripting.FileSystemObject" ); var flOutput = fso.CreateTextFile( strFullPath, true ); //true for overwrite flOutput.Write( strContent ); flOutput.Close(); } The code works fine if the text is fully Latin-9 but when the text contains even a single UTF-8 encoded character, the write fails. The ActiveX FileSystemObject does not support UTF-8, it seems. I tried UTF-16 encoding the text first but the result was garbled. What is a workaround?

  • Extract files from ZIP file with VBScript

    - by Tester101
    When extracting files from a ZIP file I was using the following. Sub Unzip(strFile) ' This routine unzips a file. NOTE: The files are extracted to a folder ' ' in the same location using the name of the file minus the extension. ' ' EX. C:\Test.zip will be extracted to C:\Test ' 'strFile (String) = Full path and filename of the file to be unzipped. ' Dim arrFile arrFile = Split(strFile, ".") Set fso = CreateObject("Scripting.FileSystemObject") fso.CreateFolder(arrFile(0) & "\ ") pathToZipFile= arrFile(0) & ".zip" extractTo= arrFile(0) & "\ " set objShell = CreateObject("Shell.Application") set filesInzip=objShell.NameSpace(pathToZipFile).items objShell.NameSpace(extractTo).CopyHere(filesInzip) fso.DeleteFile pathToZipFile, True Set fso = Nothing Set objShell = Nothing End Sub 'Unzip This was working, but now I get a "The File Exists" Error. What is the reason for this? Are there any alternatives?

  • Mercurial "hg clone" on Windows via ssh with plink issue

    - by Kyle Tolle
    I have a Windows Server 2008 machine (iis7) that has CopSSH set up on it. To connect to it, I have a Windows 7 machine with Mercurial 1.5.1 (and TortoiseHg) installed. I can connect to the server using PuTTY with a non-standard ssh port and a .ppk file just fine. So I know the server can be SSH'd into. Next, I wanted to use the CLI to connect via hg clone to get a private repo. I've seen elsewhere that you need to have ssh configured in your mercurial.ini file, so my mercurial.ini has a line: ssh = plink.exe -ssh -C -l username -P #### -i "C:/Program Files/PuTTY/Key Files/KyleKey.ppk" Note: username is filled in with the username I set up via copSSH. #### is filled in with the non-standard ssh port I've defined for copSSH. I try to do the command hg clone ssh://inthom.com but I get this error: remote: bash: inthom.com: command not found abort: no suitable response from remote hg! It looks like hg or plink parses the hostname such that it thinks that inthom.com is a command instead of the server to ssh to. That's really odd. Next, I tried to just use plink to connect by plink -P #### ssh://inthom.com, and I am then prompted for my username, and next password. I enter them both and then I get this error: bash: ssh://inthom.com: No such file or directory So now it looks like plink doesn't parse the hostname correctly. I fiddled around for a while trying to figure out how to do call hg clone with an empty ssh:// field and eventually figured out that this command allows me to reach the server and clone a test repo on the inthom.com server: hg clone ssh://!/Repos/test ! is the character I've found that let's me leave the hostname blank, but specify the repo folder to clone. What I really don't understand is how plink knows what server to ssh to at all. neither my mercurial.ini nor the command specify a server. None of the hg clone examples I've seen have a ! character. They all use an address, which makes sense, so you can connect to any repo via ssh that you want to clone. My only guess is that it somehow defaults to the last server I used PuTTY to SSH to, but I SSH'd into another server, and then tried to use plink to get to it, but plink still defaults to inthom.com (verified with the -v arg to plink). So I am at a loss as to how plink gets this server value at all. For "fun", I tried using TortoiseHg and can only clone a repo when I use ssh://!/Repos/test as the Source. Now, you can see that, since plink doesn't parse the hostname correctly, I had to specify the port number and username in the mercurial.ini file, instead of in the hostname like [email protected]:#### like you'd expect to. Trying to figure this out at first drove me insane, because I would get errors that the host couldn't be reached, which I knew shouldn't be the case. My question is how can I configure my setup so that ssh://[email protected]:####/Repos/test is parsed correctly as the username, hostname, port number, and repo to copy? Is it something wrong with the version of plink that I'm using, or is there some setting I may have messed up? If it is plink's fault, is there an alternative tool I can use? I'm going to try to get my friend set up to connect to this same repo, so I'd like to have a clean solution instead of this ! business. Especially when I have no idea how plink gets this default server, so I'm not sure if he'd even be able to get to inthom.com correctly. PS. I've had to use a ton of different tutorials to even get to this stage. Therefore, I haven't tried pushing any changes to the server yet. Hopefully I'll get this figured out and then I can try pushing changes to the repo.

  • How to handle value types when embedding IronPython in C#?

    - by kloffy
    There is a well known issue when it comes to using .NET value types in IronPython. This has recently caused me a headache when trying to use Python as an embedded scripting language in C#. The problem can be summed up as follows: Given a C# struct such as: struct Vector { public float x; public float y; } And a C# class such as: class Object { public Vector position; } The following will happen in IronPython: obj = Object() print obj.position.x # prints ‘0’ obj.position.x = 1 print obj.position.x # still prints ‘0’ As the article states, this means that value types are mostly immutable. However, this is a problem as I was planning on using a vector library that is implemented as seen above. Are there any workarounds for working with existing libraries that rely on value types? Modifying the library would be the very last resort, but I'd rather avoid that.

  • powermock : ProcessBuilder redirectErrorStream giving nullPointerException

    - by kaustubh9
    I am using powermock to mock some native command invocation using process builder. the strange thing is these test pass sometimes and fail sometimes giving a NPE. Is this a powermock issue or some gotcha in the program. the snippet of the class under test is.. public void method1(String jsonString, String filename) { try { JSONObject jObj = new JSONObject(jsonString); JSONArray jArr = jObj.getJSONArray("something"); String cmd = "/home/y/bin/perl <perlscript>.pl<someConstant>" + " -k " + <someConstant> + " -t " + <someConstant>; cmd += vmArr.getJSONObject(i).getString("jsonKey"); ProcessBuilder pb = new ProcessBuilder("bash", "-c", cmd); pb.redirectErrorStream(false); Process shell = pb.start(); shell.waitFor(); if (shell.exitValue() != 0) { throw new RuntimeException("Error in Collecting the logs. cmd="+cmd); } StringBuilder error = new StringBuilder(); InputStream iError = shell.getErrorStream(); BufferedReader bfr = new BufferedReader( new InputStreamReader(iError)); String line = null; while ((line = bfr.readLine()) != null) { error.append(line + "\n"); } if (!error.toString().isEmpty()) { LOGGER.error(error`enter code here`); } iError.close(); bfr.close(); } catch (Exception e) { throw new RuntimeException(e); } and the unit test case is .. @PrepareForTest( {.class, ProcessBuilder.class,Process.class, InputStream.class,InputStreamReader.class, BufferedReader.class} ) @Test(sequential=true) public class TestClass { @Test(groups = {"unit"}) public void testMethod() { try { ProcessBuilder prBuilderMock = createMock(ProcessBuilder.class); Process processMock = createMock(Process.class); InputStream iStreamMock = createMock(InputStream.class); InputStreamReader iStrRdrMock = createMock(InputStreamReader.class); BufferedReader bRdrMock = createMock(BufferedReader.class); String errorStr =" Error occured"; String json = <jsonStringInput>; String cmd = "/home/y/bin/perl <perlscript>.pl -k "+<someConstant>+" -t "+<someConstant>+" "+<jsonValue>; expectNew(ProcessBuilder.class, "bash", "-c", cmd).andReturn(prBuilderMock); expect(prBuilderMock.redirectErrorStream(false)).andReturn(prBuilderMock); expect(prBuilderMock.start()).andReturn(processMock); expect(processMock.waitFor()).andReturn(0); expect(processMock.exitValue()).andReturn(0); expect(processMock.getErrorStream()).andReturn(iStreamMock); expectNew(InputStreamReader.class, iStreamMock) .andReturn(iStrRdrMock); expectNew(BufferedReader.class, iStrRdrMock) .andReturn(bRdrMock); expect(bRdrMock.readLine()).andReturn(errorStr); expect(bRdrMock.readLine()).andReturn(null); iStreamMock.close(); bRdrMock.close(); expectLastCall().once(); replayAll(); <ClassToBeTested> instance = new <ClassToBeTested>(); instance.method1(json, fileName); verifyAll(); } catch (Exception e) { Assert.fail("failed while collecting log.", e); } } I get an error on execution an the test case fails.. Caused by: java.lang.NullPointerException at java.lang.ProcessBuilder.start(ProcessBuilder.java:438) Note : I do not get this error on all executions. Sometimes it passes and sometimes it fails. I am not able to understand this behavior.

  • What stack would you use for a new web Java project if you started today?

    - by Joelio
    If you were to start a brand new java project today with the following requirements: high scale (20k + users) you want to use something that is fairly mature (not changing dramatically) & wont be dead technology in 3 years you want something very productive (no server restarts in dev, save the code and its automatically compiled and deployed), productivity and time to market are key. some amount of ajax on front end no scripting language, jruby, groovy, php etc , has to be java has to support i8n What stack would you use & Why? (when I say stack, I mean, everything soup to nuts, so app server, mvc framework, bean framework, ORM framework, javascript framework etc...)

  • A CSS code to put text saved in other server into blogspot blog..???

    - by Nok Imchen
    I have a blog hosted on blogspot dot com. In that blog, i want to put some data like Google search string or etc automatically. I want it to be done in this way: Just put a code (server side scripting) linking to a text file or PHP file, and the code will extract the text and output in my blogspot blog. What i DONT want is to use javascript. Beacause, if i use javascript then the output will be seen only in the users screen. I want the output to be seen by Google Bot too. Thanking you in anticipation.

  • How to Obtain Data to Pre-Populate Forms.

    - by Stan
    The objective is to have a form reflect user's defined constraints on a search. At first, I relied entirely upon server-side scripting to achieve this; recently I tried to shift the functionality to JavaScript. On the server side, the search parameters are stored in a ColdFusion struct which makes it particularly convenient to have the data JSON'ed and sent to the client. Then it's just a matter of separately iterating over 'checkable' and text fields to reflect the user's search parameters; jQuery proved to be exceptionally effective in simplifying the workload. One observable difference lies in performance. The second method appeared to be somewhat slower and didn't work in IE8. Evidently, the returned JSON'ed struct was seen as an empty object. I'm sure it can be fixed, though before spending any more time with it, I'm curious to hear how others would approach the task. I'd gladly appreciate any suggestions. --Stan

  • How do I choose files from the local filesystem in Windows Phone 7

    - by Kris Erickson
    I'm trying to choose some files to upload in Windows Phone 7 (in the emulator), and any attempt to ShowDialog of the OpenFileDialog leads to a Security Exception. The open file dialog is being called from an event on a button click but I get a SecurityException [FileDialog_ActiveScripting] Arguments: Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=3.0.40806.0&File=System.Windows.dll&Key=FileDialog_ActiveScripting Looking up the SecurityException in the Silverlight version of OpenFileDialog.ShowDialog states that the error is: Active Scripting in Internet Explorer is disabled. -or- The call to the ShowDialog method was not made from user-initiated code. Anyone had any luck with the OpenFileDialog and ShowDialog in Windows Phone 7?

  • Tools for website development

    - by sharkin
    Hi! I can't find any other post which addresses this topic on a purely general level. I'm very unexperienced in developing full scale websites. I get around using HTML and PHP for simple tasks. Now I'm looking at developing a more elaborate site and want to get hold of a good tool which doesn't eat my wallet to the bones. I guess I should add more intelligent text here about what I expect it to be capable of, but I really don't know so much. I guess the code/design/preview style in dreamweaver appealed to me, and I'm definetely going to use scripting like PHP or ASP.NET, some database work etc. I guess pretty much the standard (?) website development tasks. So, are there good tools out there I should be looking at?

  • Storing ASP.Net MVC Views in the Database

    - by Adam Albrecht
    For an ASP.Net MVC application, I'm interested in storing some views and/or partial views in the database so that a few semi-technical users can do some basic view logic. Does anyone have any tips or lessons from experience on doing this? I know Phil Haack wrote a blog post on this about a year ago. He used IronRuby for scripting his views, (which would be fine for me). He created a quick proof-of-concept, but I can't find any other information on the topic. Any ideas, thoughts, tips, etc would be appreciated. Thanks!

  • Load HTML frames in a specific order without back button problems?

    - by Joergen Bech
    I have a web page that uses a frameset. Due to scripting and object dependencies, I need to load the frames in a specific order. I have used this example as a template: The JavaScript Source: Navigation: Frames Load Order This loads an empty page in place of the page I need to load last, then replaces it with the correct page after the first page has loaded. However: I also need to use the browser Back button. If you run the sample at the above link, let both frames load, then click the Back button, the top frame reverts to the temporary blank page. It is then necessary to click the Back button again to navigate to the page before the frameset. Is there a way to force frames to load in a specific order without this Back button behavior - or a way to force the Back button to skip the empty page? This needs to work with Internet Explorer 6 and 7 and preferably with Firefox 3 as well.
