  • How to create a default association for files with no extension

    - by acidzombie24
    I am using http://www.pnotepad.org/ (i wouldnt mind switching to something else if it lightweight and has most/all features i like which i'll check on a app by app basis) When i create a new tab/file and save it unless i write .txt i get a file with no extention. Which makes it hard to open since i cant double click it (i dont think i can tell win7 to set a default app for files with no extension) How do i make pnotepad save with a .txt when non are specified?

  • Cross-site json rpc : Python server side and Mozilla extension using Javascript client side

    - by jknair
    hello, I am building a mozilla extension that contacts a python application on a remote server to send and receive data. The python application can be used using xml-rpc from a python console.I am given the task to design a json-rpc that would contact the same application.Making the python server side has been easy which can be accesed using python console but making the mozilla extension to connect to the python serverside is what i am not understanding howto ??? how do i make cross site json rpc calls i have gone through a lot of libraries that i can find on googling but none of them seem to work i am not sure if it is because of same origin policy or my server side not able to process the data ???

  • Downloading Python 2.5.4 (from official website) in order to install it

    - by brilliant
    I was quite hesitant about whether I should post this question here on "StackOverflow" or on "SuperUser", but finally decided to post it here as Python is more a programming language rather than a piece of software. I've been recently using Python 2.5.4 that is installed on my computer, but at the moment I am not at home (and won't be for about two weeks from now), so I need to install the same version of Python on another computer. This computer has Windows XP installed – just like the one that I have at home. The reason why I need Python 2.5.4 is because I am using “Google App Engine”, and I was told that it only supports Python 2.5 However, when I went to the official Python page for the download, I discovered that certain things have changed, and I don’t quite remember where exactly from that site I had downloaded Python 2.5.4 on my computer at home. I found this page: http://www.python.org/download/releases/2.5.4/ Here is how it looks: (If you can’t see it here, please check it out at this address: http://brad.cwahi.net/some_pictures/python_page.jpg ) A few things here are not clear to me. It says: “For x86 processors: python-2.5.4.msi For Win64-Itanium users: python-2.5.4.ia64.msi For Win64-AMD64 users: python-2.5.4.amd64.msi” First of all, I don’t know what processor I am using – whether mine is “x86” or not; and also, I don’t know whether I am an “Win64-Itanium” or an “Win64-AMD64” user. Are Itanium and AMD64 also processors? Later it says: “Windows XP and later already have MSI; many older machines will already have MSI installed.” I guess, it is my case, but then I am totally puzzled as to which link I should click as it seems now that I don’t need those three previous links (as MSI is already installed on Windows XP), but there is no fourth link provided for those who use “Windows XP” or older machines. Of course, there are these words after that: “Windows users may also be interested in Mark Hammond's win32all package, available from Sourceforge.” but it seems to me that it is something additional rather than the main file. So, my question is simple: Where in the official Python website I can download Python 2.5.4, precisely, which link I should click?

  • Boost Python - Limits to the number of arguments when wrapping a function

    - by Derek
    I'm using Boost Python to wrap some C++ functions that I've created. One of my C++ functions contains 22 arguments. Boost complains when I try to compile my solution with this function, and I'm trying to figure out if it is just because this function has too many arguments. Does anyone know if such a limit exists? I've copied the error I'm getting below, not the code because I figure someone either knows the answer to this or not - and if there is no limit then I'll just try to figure it out myself. Thanks very much in advance! Here is a copy of the beginning of the error message I receive... 1>main.cpp 1>c:\cpp_ext\boost\boost_1_47\boost\python\make_function.hpp(76): error C2780: 'boost::mpl::vector17<RT,most_derived<Target,ClassT>::type&,T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14> boost::python::detail::get_signature(RT (__thiscall ClassT::* )(T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14) volatile const,Target *)' : expects 2 arguments - 1 provided 1>c:\cpp_ext\boost\boost_1_47\boost\python\signature.hpp(236) : see declaration of 'boost::python::detail::get_signature' And eventually I get about a hundred copies of error messages very much resembling this one: 1>c:\cpp_ext\boost\boost_1_47\boost\python\make_function.hpp(76): error C2784: 'boost::mpl::vector17<RT,ClassT&,T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14> boost::python::detail::get_signature(RT (__thiscall ClassT::* )(T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14) volatile const)' : could not deduce template argument for 'RT (__thiscall ClassT::* )(T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14) volatile const' from 'std::string (__cdecl *)(const std::string &,jal::date::JULIAN_DATE,const std::string &,const std::string &,int,const std::string &,const std::string &,const std::string &,const std::string &,const std::string &,const std::string &,int,const std::string &,const std::string &,int,const std::string &,const std::string &,const std::string &,const std::string &,const std::string &,int,const std::string &)' 1> c:\cpp_ext\boost\boost_1_47\boost\python\signature.hpp(218) : see declaration of 'boost::python::detail::get_signature' 1>c:\cpp_ext\boost\boost_1_47\boost\python\make_function.hpp(76): error C2780: 'boost::mpl::vector17<RT,most_derived<Target,ClassT>::type&,T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14> boost::python::detail::get_signature(RT (__thiscall ClassT::* )(T0,T1,T2,T3,T4,T5,T6,T7,T8,T9,T10,T11,T12,T13,T14) volatile,Target *)' : expects 2 arguments - 1 provided 1> c:\cpp_ext\boost\boost_1_47\boost\python\signature.hpp(236) : see declaration of 'boost::python::detail::get_signature'

  • Invoke Python modules from Java

    - by user36813
    I have a Python interface of a graph library written in C - igraph (the name of library). My need is to invoke the python modules pertaining to this graph library from Java code. It goes like this, the core of library is in c. This core has been imported into Python and interfaces to the functions embedded in core are available in Python. My project's rest of the code is in Java and hence I would like to call the graph functions by Java as well. Jython - which lets you invoke python modules with in Java was an option.I went on trying Jython to discover that it will not work in my case as the core code is in C and Jython wont support anything that is imported as a c dll in python code.I also thought of opting for the approach of calling graph routines directly in c. That is without passing through Python code. I am assuming there must be something which lets you call c code from Java, how ever I am not good in C hence I did not go for it. My last resort seems to execute Python interpreter from command line using Java. But that is a dirty and shameless. Also to deal with the results produced by Python code I will have to write the results in a file and read it back in java. Again dirty way. Is there something that any one can suggest me? Thanks to every one giving time. Thanks Igal for answering. I had a look at it. At first glance it appears as if it is simply calling the python script. Jep jep = new Jep(false, SCRIPT_PATH, cl); jep.set("query", query); jep.runScript(SCRIPT_PATH + file); jep.close(); Isnt it very similar to what we would do if called the python interpreter from command line through a Java code. Runtime runtime = Runtime.getRuntime(); Process proc = runtime.exec("python test.py"); Concern is how do I use the results generated by Python script. The naive way is to write them to file and read it back in Java. I am searching for a smarter approach.Thanks for suggestion anyway.

  • Python server does not excecute PHP script: permission denied

    - by krisvandenbergh
    I am trying to execute a PHP file through a Python server. However, I get the following error: File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/CGIHTTPServer.py", line 255, in run_cgi os.execve(scriptfile, args, os.environ) OSError: [Errno 13] Permission denied The python server is running though. What have I done so far? Chmod'ed recursively all directories to (chmod -R a+x) (I know this is not secure but its just for testing purposes) for both Python installation directories and my scripts. Tried to find out if python server is running as root through ps aux grep py I am out of ideas. What could be going wrong else? Thanks for the feedback.

  • Installing TKInter for Python 2.6.5

    - by Azfar
    Well today's been a bit of shock. After running port -v selfupdate followed by an attempt to run sudo port install py26-ipython MacPorts went around installing a whole host of stuff, including updating my Python from 2.6.4 to 2.6.5. It's nice but unexpected in a creepy way. So I tried to install TKInter using MacPorts with port search tkinter yielding: py-tkinter @2.4.6 (python, graphics) Python bindings to the Tk widget set py25-tkinter @2.5.4 (python, graphics) This is a stub. tkinter is now built with python25 Found 2 ports. So I tried sudo port install py25-tkinter and then it tries to install Python 2.5.5. There must be an easier way to install TkInter without being faffed around... help please?

  • How to specify or add directory to Python.h search path during setup.py build/install

    - by ca2longoria
    I'm running Linux, and have downloaded a python module I must install without access to any but my particular /home/user directory (I have no root privileges nor the option to pursue them). This of course requires the Python source. This I've downloaded and have laying around in said user directory. While asking the admin to copy the proper files into /usr/include/python2.7 is the easiest way to go about this, I am hoping for a more general and portable solution to this kind of problem. Changing only data in the module source (MANIFEST.in, README.txt, setup.py, etc.), how might I add an arbitrary directory to the search path for Python.h and friends? (Without a solution, "python setup.py build" will continue returning with the "Python.h: No such file or directory" error) Thank you very much. (Additionally, is it acceptable to post this both here and on StackOverflow?)

  • Desktop file for my Python script

    - by Jason94
    I would like to make a .desktop file for my Python script, but so far the only thing i have is a clickable icon on my desktop! It does nothing when I click it, so im guessing there is something wrong with the execution :) The desktop file: [Desktop Entry] Version=1.0 Type=Python Exec=/home/user/MyDocs/Python/EasySteer/Main.py Name=EasySteer Icon=steering_wheel X-Icon-Path=/usr/share/icons and I also tried: [Desktop Entry] Version=1.0 Type=Application Exec=/usr/bin/xterm "python /home/user/MyDocs/Python/EasySteer/Main.py" Name=EasySteer Icon=steering_wheel X-Icon-Path=/usr/share/icons But nothing works :D if it matters this is for my Nokia N900 mobile phone that runs Maemo linux, but I think the basics are the same.

  • What are the packages/libraries I should install before compiling Python from source?

    - by Lennart Regebro
    Once in a while I need to install a new Ubuntu (I used it both for desktop and servers) and I always forget a couple of libraries I should have installed before compiling, meaning I have to recompile, and it's getting annoying. So now I want to make a complete list of all library packages to install before compiling Python (and preferably how optional they are). This is the list I compiled with below help and by digging in setup.py. It is complete for Ubuntu 10.04 and 11.04 at least: build-essential (obviously) libz-dev (also pretty common and essential) libreadline-dev (or the Python prompt is crap) libncursesw5-dev libssl-dev libgdbm-dev libsqlite3-dev libbz2-dev More optional: tk-dev libdb-dev Ubuntu has no packages for v1.8.5 of the Berkeley database, nor (for obvious reasons) the Sun audio hardware, so the bsddb185 and sunaudiodev modules will still not be built on Ubuntu, but all other modules are built with the above packages installed. Python 2.5 and Python 2.6 also needs to have LDFLAGS set on Ubuntu 11.04 and later, to handle the new multi-arch layout: export LDFLAGS="-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)" For Python 2.6 and 2.7 you also need to explicitly enable SSL after running the ./configure script and before running make. In Modules/Setup there are lines like this: #SSL=/usr/local/ssl #_ssl _ssl.c \ # -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ # -L$(SSL)/lib -lssl -lcrypto Uncomment these lines and change the SSL variable to /usr: SSL=/usr _ssl _ssl.c \ -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \ -L$(SSL)/lib -lssl -lcrypto Python 2.6 also needs Modules/_ssl.c modified to be used with OpenSSL 1.0, which is used in Ubuntu 11.10. At around line 300 you'll find this: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ Change that into: else if (proto_version == PY_SSL_VERSION_SSL3) self->ctx = SSL_CTX_new(SSLv3_method()); /* Set up context */ #ifndef OPENSSL_NO_SSL2 else if (proto_version == PY_SSL_VERSION_SSL2) self->ctx = SSL_CTX_new(SSLv2_method()); /* Set up context */ #endif else if (proto_version == PY_SSL_VERSION_SSL23) self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */ This disables SSL_v2 support, which apparently is gone in OpenSSL1.0.

  • How do I unescape HTML entities in a string in Python 3.1?

    - by Sho Minamimoto
    I have looked all around and only found solutions for python 2.6 and earlier, NOTHING on how to do this in python 3.X. (I only have access to Win7 box.) I HAVE to be able to do this in 3.1 and preferably without external libraries. Currently, I have httplib2 installed and access to command-prompt curl (that's how I'm getting the source code for pages). Unfortunately, curl does not decode html entities, as far as I know, I couldn't find a command to decode it in the documentation. YES, I've tried to get Beautiful Soup to work, MANY TIMES without success in 3.X. If you could provide EXPLICIT instructions on how to get it to work in python 3 in MS Windows environment, I would be very grateful. So, to be clear, I need to turn strings like this: Suzy &amp; John into a string like this: "Suzy & John".

  • Automate Google Chrome extension installation

    - by gtaborga
    Hi everyone, I am working on creating a Google Chrome extension. We have it included in an automated build system and since it is constantly being worked on we need a solution to be able to package the extension as a .crx file which according to http://code.google.com/chrome/extensions/packaging.html can easily be scripted. My question is after packaging the extension is there a known method either through the command-line or some other programmatic way, to install the newly packaged extension in an automated manner? If someone knows how or has any reference material that I can be pointed towards I would greatly appreciate any help that is offered. Thank you.

  • Chrome Extension - Cross-Origin XMLHttpRequest - Returning HTML/JSON

    - by Tyler
    Hi everyone, I hope you can help me :) I've created a Chrome extension (my first one) and I'm having some difficulty auto-populating a <select> with <option> that are being returned. the default_popup page is index.htm. I have two <select> (listboxes? can't remember the name) boxes. When a user first clicks the extension, it performs a XMLHttpRequest to a php script and get's a list of names from a MySQL database. It returns (onLoad) the list in the form of: <option>blah</option> When a user selects an option from the first listbox/select, it performs another XMLHttpRequest and auto-populates the second listbox/select. Then when a user selects an option from the second listbox it will eventually populate a few details further down the page. I've been testing by just running the index.htm file and seeing if just the code works correctly, which it does. However when trying to view it from the extension, it doesn't work. The onLoad doesn't fill in the first listbox, and selecting an option (one that I typed in the box for testing purposes) from the first listbox doesn't populate the second listbox. I thought maybe it was a permissions error, so I tried adding the domain to the manifest.json file; but I appear to be getting an error in the manifest.json file after doing so. In my default_popup (index.htm) file I have this script for my XMLHttpRequest: <script type="text/javascript"> function getClient(str,type) { if (str=="") { document.getElementById(type).innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById(type).innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","http://(domain removed)/Extension/getInfo.php?q="+type+"&c="+str,true,"user","pass"); xmlhttp.send(); } </script> This is what my manifest.json file looks like: { "name": "Client Center Lite", "version": "1.0", "description": "blah", "browser_action": { "default_icon": "images/icon_19.png", "default_popup": "index.htm", "default_title": "Client Center Lite" }, "icons":{ "128":"images/icon_128.png" } "permissions": { "http://(domain removed)/" }, } Am I doing this correctly? The point of the extension is to be able to quickly view client details. The extension will only be given to employees locally in a .crx file, and not distributed online. The domain I am accessing through the PHP/MySQL is accessible from the web, but I'm currently using localhost in my mysql_connect string. Do I need to be returning the <option> elements encoded as JSON? If so, I'm completely cluesless as how to do that.

  • Problem installing PEAR package with GMP extension requirement

    - by user339122
    I want to install the Crypt_DiffieHellman PEAR package, that gives me the following error: pear/Crypt_DiffieHellman requires PHP extension "gmp" So I installed the gmp extension (using MacPorts' "php5-gmp"), both php -m and extension_loaded('gmp') indicate that the extension is loaded. However I still get the PEAR error when I try to install the package. Am I missing something here? Or is this a (known) bug with the package/PEAR installer?

  • firefox extension and ie8 plugin compatibility

    - by Ke
    hi, im a bit new at extension development, but im about to embark upon a project to build a ffox extension. Does anyone know if its possbile, with minimal adaption, to make a firefox extension compatible with ie8 as a plugin and if so, are there any caveats i should be aware of? I guess its just javascript code wrapped around the ffox or ie8 wrapper, but would really appreciate to learn from someone who has experience. Cheers Ke

  • chrome extension login security with iframe

    - by Weaver
    I should note, I'm not a chrome extension expert. However, I'm looking for some advice or high level solution to a security concern I have with my chrome extension. I've searched quite a bit but can't seem to find a concrete answer. The situation I have a chrome extension that needs to have the user login to our backend server. However, it was decided for design reasons that the default chrome popup balloon was undesirable. Thus I've used a modal dialog and jquery to make a styled popup that is injected with content scripts. Hence, the popup is injected into the DOM o the page you are visiting. The Problem Everything works, however now that I need to implement login functionality I've noticed a vulnerability: If the site we've injected our popup into knows the password fields ID they could run a script to continuously monitor the password and username field and store that data. Call me paranoid, but I see it as a risk. In fact,I wrote a mockup attack site that can correctly pull the user and password when entered into the given fields. My devised solution I took a look at some other chrome extensions, like Buffer, and noticed what they do is load their popup from their website and, instead, embed an iFrame which contains the popup in it. The popup would interact with the server inside the iframe. My understanding is iframes are subject to same-origin scripting policies as other websites, but I may be mistaken. As such, would doing the same thing be secure? TLDR To simplify, if I embedded an https login form from our server into a given DOM, via a chrome extension, are there security concerns to password sniffing? If this is not the best way to deal with chrome extension logins, do you have suggestions with what is? Perhaps there is a way to declare text fields that javascript can simply not interact with? Not too sure! Thank you so much for your time! I will happily clarify anything required.

  • Google chrome extension: local storage

    - by Rohan
    Hi there I'm developing an extension for Google Chrome, and have run into some trouble.I created an options.html page and added it to the manifest.json file.The page shows properly. I saved the options, and then went back to the page on which the extension is supposed to run. Unfortunately, the Local storage for the options was returning a 'null' instead of the option. If I set the local storage option directly from the extension's JS script, it works fine but not if it was set from the options page. Any idea how i can access the options.html local storage values from my Javascript file in the extension? thanks!

  • C# naming convention for extension methods for interface

    - by Sarah Vessels
    I typically name my C# interfaces as IThing. I'm creating an extension method class for IThing, but I don't know what to name it. On one hand, calling it ThingExtensions seems to imply it is an extension class to some Thing class instead of to the IThing interface. It also makes the extension class be sorted away from the interface it extends, when viewing files alphabetically. On the other hand, naming it IThingExtensions makes it look like it is an interface itself, instead of an extension class for an interface. What would you suggest?

  • Extension methods for encapsulation and reusability

    - by tzaman
    In C++ programming, it's generally considered good practice to "prefer non-member non-friend functions" instead of instance methods. This has been recommended by Scott Meyers in this classic Dr. Dobbs article, and repeated by Herb Sutter and Andrei Alexandrescu in C++ Coding Standards (item 44); the general argument being that if a function can do its job solely by relying on the public interface exposed by the class, it actually increases encapsulation to have it be external. While this confuses the "packaging" of the class to some extent, the benefits are generally considered worth it. Now, ever since I've started programming in C#, I've had a feeling that here is the ultimate expression of the concept that they're trying to achieve with "non-member, non-friend functions that are part of a class interface". C# adds two crucial components to the mix - the first being interfaces, and the second extension methods: Interfaces allow a class to formally specify their public contract, the methods and properties that they're exposing to the world. Any other class can choose to implement the same interface and fulfill that same contract. Extension methods can be defined on an interface, providing any functionality that can be implemented via the interface to all implementers automatically. And best of all, because of the "instance syntax" sugar and IDE support, they can be called the same way as any other instance method, eliminating the cognitive overhead! So you get the encapsulation benefits of "non-member, non-friend" functions with the convenience of members. Seems like the best of both worlds to me; the .NET library itself providing a shining example in LINQ. However, everywhere I look I see people warning against extension method overuse; even the MSDN page itself states: In general, we recommend that you implement extension methods sparingly and only when you have to. So what's the verdict? Are extension methods the acme of encapsulation and code reuse, or am I just deluding myself?

  • When and why are you planning to upgrade to Python 3.0?

    - by Tomislav Mutak
    Python 3.0 (aka Python 3000, Py3k, etc) is now available. When and why are you planning on porting your project or code to the new Python? edit: I'm particularly interested in any features that don't exist in 2.6 that make porting worth it. Right now seems like a lot of negatives (x hasn't been ported yet), but I don't know what people see as the positives. Regarding "when", I'm interested in people's thoughts that the first step to porting is to have "excellent test coverage" which seems a bit optimistic for some projects.

  • Are there any Python reference counting/garbage collection gotchas when dealing with C code?

    - by Jason Baker
    Just for the sheer heck of it, I've decided to create a Scheme binding to libpython so you can embed Python in Scheme programs. I'm already able to call into Python's C API, but I haven't really thought about memory management. The way mzscheme's FFI works is that I can call a function, and if that function returns a pointer to a PyObject, then I can have it automatically increment the reference count. Then, I can register a finalizer that will decrement the reference count when the Scheme object gets garbage collected. I've looked at the documentation for reference counting, and don't see any problems with this at first glance (although it may be sub-optimal in some cases). Are there any gotchas I'm missing? Also, I'm having trouble making heads or tails of the cyclic garbage collector documentation. What things will I need to bear in mind here? In particular, how do I make Python aware that I have a reference to something so it doesn't collect it while I'm still using it?

  • How do I set sys.excepthook to invoke pdb globally in python?

    - by saffsd
    From Python docs: sys.excepthook(type, value, traceback)¶ This function prints out a given traceback and exception to sys.stderr. When an exception is raised and uncaught, the interpreter calls sys.excepthook with three arguments, the exception class, exception instance, and a traceback object. In an interactive session this happens just before control is returned to the prompt; in a Python program this happens just before the program exits. The handling of such top-level exceptions can be customized by assigning another three-argument function to sys.excepthook. http://docs.python.org/library/sys.html How do I modify this globally so the default action is to always invoke pdb? Is there a configuration file I can change? I don't want to wrap my code to do this.
