  • Parse http GET and POST parameters from BaseHTTPHandler?

    - by ataylor
    BaseHTTPHandler from the BaseHTTPServer module doesn't seem to provide any convenient way to access http request parameters. What is the best way to parse the GET parameters from the path, and the POST parameters from the request body? Right now, I'm using this for GET: def do_GET(self): parsed_path = urlparse.urlparse(self.path) try: params = dict([p.split('=') for p in parsed_path[4].split('&')]) except: params = {} This works for most cases, but I'd like something more robust that handles encodings and cases like empty parameters properly. Ideally, I'd like something small and standalone, rather than a full web framework.

  • how to lengthen the pause between the words with text-to-speech (pyTTS or SAPI5)

    - by Berry Tsakala
    Is it possible to extend the gap between spoken words when using text to speech with SAPI5 ? The problem is that esp. with some voices, the words are almost connected to each other, which makes the speech more difficult to understand. I'm using python and pyTTS module (on windows, since it's using SAPI) I tried to hook to the OnWord event and add a time.sleep() or tts.Pause(), but apparently even though all the events are caught, they are being processed only at the end of the spoken text, whether i'm using the sync or async flag. In this NON WORKING example, the sleep() method is executed only after the sentence is spoken: tts = pyTTS.Create() def f(x): tts.Pause() sleep(0.5) tts.Resume() tts.OnWord = f tts.Speak(text)

  • How to install python physics engine

    - by None
    I want a python physics engine that works on mac and makes it easy to simulate physics. I have VPython and it works fine, but it is not quite what I want. VPython just shows visual elements and all the physics is in formulas. I looked at the documentation for PyODE and it looked like more what I want. It allowed you to add forces to masses and have worlds and things like that. When I tried to install PyODE (I am using a Mac), it didn't work. One reason was that I didn't have pyrex (I do have Cython, so maybe there is some way to have it use that?), but the other was that I didn't have ode installed. I looked and realized that PyODE is dependent on ode. I tried to install ode but that didn't work. Is there some documentation or binary or something that makes it easy to install PyODE on a mac? Or is there a similar module?

  • How to render a Partial from a Model in Rails 2.3.5

    - by empire29
    I have a Rails 2.3.5 application and Im trying to render several Partials from within a Model (i know, i know -- im not supposed to). The reason im doing this is im integrating a Comet server (APE) into my Rails app and need to push updates out based on the Model's events (ex. after_create). I have tried doing this: ActionView::Base.new(Rails::Configuration.new.view_path).render(:partial => "pages/show", :locals => {:page => self}) Which allows me to render simple partials that don't user helpers, however if I try to user a link_to in my partial, i receive an error stating: undefined method `url_for' for nil:NilClass I've made sure that the object being passed into the "project_path(project)" is not nil. I've also tried including: include ActionView::Helpers::UrlHelper include ActionController::UrlWriter in the Module that contains the method that makes the above "render" call. Does anyone know how to work around this? Thanks

  • How do I add application specific code to Rails' plugin?

    - by Waseem
    Hi, I am using facebooker in one of my applications. I want to add some application specific methods to various methods in it? e.g. In facebooker/lib/facebooker/models/user.rb module Facebooker class User # I want to add my methods here. for e.g my_method end end I can not directly put my_method in the plugin itself since I also want to access my models from there. Not defining the methods in plugin code itself will also be helpful when I upgrade.

  • installing simplejson on the google appengine

    - by user266564
    Super nub question time! I am trying to use simplejson on the google appengine. In a terminal on my machine I have simplejson installed and working. But my when I try to import it in a script running on the appengine I get an error saying no such library exists. If open the interactive console on my machine (from the link on http://localhost:8080/_ah/admin) and type "import simplejson" I get: Traceback (most recent call last): File "/home/chris/google_appengine/google/appengine/ext/admin/init.py", line 210, in post exec(compiled_code, globals()) File "", line 1, in ImportError: No module named simplejson Any thoughts?

  • Python encoding for pipe.communicate

    - by Brian M. Hunt
    I'm calling pipe.communicate from Python's subprocess module from Python 2.6. I get the following error from this code: from subprocess import Popen pipe = Popen(cwd) pipe.communicate( data ) For an arbitrary cwd, and where data that contains unicode (specifically 0xE9): Exec. exception: 'ascii' codec can't encode character u'\xe9' in position 507: ordinal not in range(128) Traceback (most recent call last): ... stdout, stderr = pipe.communicate( data ) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 671, in communicate return self._communicate(input) File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/subprocess.py", line 1177, in _communicate bytes_written = os.write(self.stdin.fileno(), chunk) This is happening, I presume, because pipe.communicate() is expecting ASCII encoded string, but data is unicode. Is this the problem I'm encountering, and i sthere a way to pass unicode to pipe.communicate()? Thank you for reading! Brian

  • How does this ruby custom accessor work

    - by ennuikiller
    So the method below in class_eval dynamically creates accessors for attributes defined at runtime. It can be used, for example, to create configuration objects with attributes read from a config file (and unknown until runtime). I understanding all of it except for the else branch. If I am correct the else branch returns the attribute value (val[0]) if there is one value passed in *val. However the way its written I would expect it to return an array (val) if there is more then one value passed in *var. In particular, if I have something like the following: value = 5 then from reading the code I would expect "#{@value}" to be [=,5]. However "#{@value}" returns 5 and not the array [=,5]. How is this possible? class Module def dsl_accessor(*symbols) symbols.each do |sym| class_eval %{ def #{sym}(*val) if val.empty? @#{sym} else @#{sym} = val.size == 1 ? val[0] : val end end } end end end

  • Logging Mechanism using memory mapping technique

    - by Tushar
    Just create a mapping of the file of the required size (CreateFileMapping or mmap), write the lines in the buffer and start over when the maximum number is reached. -- Your answer for write-a-circular-file-in-c. I am also writing the LogWriter module. In this caase i am mapping the whole file to the memory using mmap(). I am maintaining the Read and Write pointers.I want to write the log to the file in append mode. Then when logger service is started first time it writes it appends the logs. But when system gets shutdown next time when i run the service it doesn't append the data at the end. I want to maintain the write and read offsets even if system shut down.How to achieve this ..? How to find the how much data is written to the log file. ??

  • ASP.Net Response Filter Clashing with SharePoint 2010 Publishing Site Defaults

    - by Jason Weber
    Hello everyone, I'm debugging an HttpModule with an ASP.NET response filter. This dynamically rewrites portions of rendered SharePoint WCM pages. The publishing pages render fine in SP2007 on both Server 2003 and Server 2008. However the equivalent pages fail to render in SP2010 B2 on Server 2008 R2 / IIS7. The following error is returned by ASP.NET: Post cache substitution is not compatible with modules in the IIS integrated pipeline that modify the response buffers. Either a native module in the pipeline has modified an HTTP_DATA_CHUNK structure associated with a managed post cache substitution callback, or a managed filter has modified the response. This error is consistent with KB #2014472. However: Caching is disabled for anonymous & authenticated access at the site collection level There do not appear to be any Substitution controls on either the master or layout page The IIS 7 settings are all stock default This is happening e.g. on /pages/default.aspx. It seems likely I'm missing something cache related...but what?

  • problems importing ttk from tkinter in python 2.7

    - by Benjimin Boyce
    I'm working with an example file in a tutorial that asks me to first do two imports: from tkinter import * from tkinter import ttk I get an error. I researched a bit and found that in python 2.7.x I need to capitalize the 't'in tkinter, so I change to: from Tkinter import * from Tkinter import ttk. the first line no longer gives and error, but I still get error: ImportError: cannot import name ttk. I have researched this issue on this site and other places, and cannot seem to understand what this ttk is. I'm further confused by the fact that, when I go to the python interpreter, and I type "help()", then "modules", and then "ttk" it seems to know what it is, and gives me a lot of description, for example: "DESCRIPTION This module provides classes to allow using Tk themed widget set." -however, python won't let me import it.

  • How to add classes for styling to Drupal when using menu_block?

    - by VoY
    I'm using the menu_block module in Drupal for my menus. This works very well, but I want my menu items styled as an image menu. This cannot be done nicely with the default settings - the menu items look something like this: <li class="leaf first menu-mlid-199"><a href="/this/is/some/nice/url" title="Homepage">Homepage</a></li> I'm guessing I could used the menu-mlid-199 class to get the styling I want, because it's a unique id of each menu item, but that seems rather ugly to me. Is there any other way to add reasonably named classes to my menu items, e.g. generate them from the page title or url alias? Even just a sequence would seem nicer - like menu-item-1 and so on.

  • Simple Python Challenge: Fastest Bitwise XOR on Data Buffers

    - by user213060
    Challenge: Perform a bitwise XOR on two equal sized buffers. The buffers will be required to be the python str type since this is traditionally the type for data buffers in python. Return the resultant value as a str. Do this as fast as possible. The inputs are two 1 megabyte (2**20 byte) strings. The challenge is to substantially beat my inefficient algorithm using python or existing third party python modules (relaxed rules: or create your own module.) Marginal increases are useless. from os import urandom from numpy import frombuffer,bitwise_xor,byte def slow_xor(aa,bb): a=frombuffer(aa,dtype=byte) b=frombuffer(bb,dtype=byte) c=bitwise_xor(a,b) r=c.tostring() return r aa=urandom(2**20) bb=urandom(2**20) def test_it(): for x in xrange(1000): slow_xor(aa,bb)

  • What's the best way to customize / add pages to the admin generator?

    - by Guillaume Flandre
    I'm using Symfony 1.4 and Doctrine. My application's backend was built using Symfony's admin generator. It works great when I want to display basic stuff. But tehre's not a lot of documentation on how to enhance it and add new pages. Let's take an example: I want to list published items on one page and to-be-published items on another one. I've used several ways to that in my application but can't figure out what the best way is: playing with filters and then modify templates depending on where you are? creating another module calling a different table_method? some other technique I don't know about? What's the best practice here? How do you guys usually do to customize your admin?

  • MIDlet + BlackBerry API = verification error?

    - by Kilnr
    Hi, Is there any way to write a MIDlet, but still use BlackBerry API classes and functions (including the APIs that require code signing)? In particular, I'm trying to use Kuix (http://www.kalmeo.org/projects/kuix). A pure MIDlet + Kuix (so without BlackBerry stuff) works perfectly after I converted the jar/jad to a cod file. As soon as I add BlackBerry API-stuff (CoverageInfo.COVERAGE_DIRECT in this case) I get a verification error when trying to run the cod file: Error starting $name: Module $name has verification error 2410 at offset 9a4f What can I do to solve this?

  • Good reasons to migrate PHP libraries to namespaces

    - by Joseph Mastey
    I have a significant number of object libraries written for PHP 5.2.5, and I'm trying to weigh the benefits of retrofitting them for namespaces. I don't have any concerns about the server PHP version at the moment, since any relevant machines are under my control, so I'm not worried about backwards compatibility. As far as the structure of the libraries, I use the same convention as Zend Framework, (Library_Module_Class_Name e.g.) so I don't currently have any naming conflicts internal to the libraries. I'd anticipate moving the Library and Module parts of those classnames to namespaces. That said, if the code is already written, is there any good reason to move over to namespaces? Thanks, Joe

  • How to use EJB 3.1 DI in Servlet ? (Could not inject session bean by @EJB from web application)

    - by kislo_metal
    I am tying to merging web application(gwt, jpa) to an separate 2 application(business login in ejb/jpa and web client in gwt). Currently i can`t inject my beans from web application (simple servlet) I am using glassfish v3. module limbo(ejb jar) is in dependency of module lust (war).

  • Weird Facebooker Plugin & Pushion Passenger ModRails Production Error

    - by Ranknoodle
    I have an application (Rails 2.3.5) that I'm deploying to production Linux/Apache server using the latest Phushion Passenger/Apache Module 2.2.11 version. After deploying my original application, it returns a 500 error with no logging to production log. So I created a minimal test rails application, with some active record calls to the database to print out a list of objects to the home controller/my index page. I also cleared out all plugins. That works fine in the production environment. Then I one by one introduced each plugin that I'm using one at a time. Every plugin works fine EXCEPT facebooker. Every time I load the facebooker plugin into my app/vendor/plugins directory (via script git etc) my test application break (500 error - no error logging). Everytime I remove the facebooker plugin my test application works. Has anyone seen this before/ have any solutions? I saw this solution but didn't see it in the facebooker code.

  • When debugging on WinCE, how can I set Visual Studio to always load symbol files it knows about?

    - by tsellon
    I'm debugging a WinCE, C++ program in Visual Studio across an ActiveSync connection. Every time I start the process it fails to load symbol information. However, if I right click on the module and hit 'Load Symbols' it correctly locates the symbol information without any further prompting from me. Is there a way that I can set Visual Studio to either: (a) automatically load this symbol information, or (b) automatically break the process into the debugger once it's loaded (similar to what windbg does)? I'm guessing there's a setting somewhere, but I've yet to find it. Update: I forgot to mention in the original question that I'm not debugging with the instance of Visual Studio that created the exe.

  • creating my own context processor in django

    - by dotty
    Hay, I have come to a point where i need to pass certain variables to all my views (mostly custom authentication type variables). I was told writing my own context processor was the best way to do this, but i am having some issues. My settings file looks like this TEMPLATE_CONTEXT_PROCESSORS = ( "django.contrib.auth.context_processors.auth", "django.core.context_processors.debug", "django.core.context_processors.i18n", "django.core.context_processors.media", "django.contrib.messages.context_processors.messages", "sandbox.context_processors.say_hello", ) As you can see i have a module called 'context_processors' and a function within that called 'say_hello'. This looks like def say_hello(request): return { 'say_hello':"Hello", } Am i right to assume i can now do this within my views {{ say_hello }} because it doesn't return anything.

  • Choosing routing.yml based on user culture?

    - by Erland Wiencke
    In my Symfony application I would like to choose the routing.yml based on the current user's culture; 'en' => routing.en.yml 'no' => routing.no.yml and so forth. Any suggestion to how this can be done? Edit: I am not trying to do i18n this way - I use Symfony's built-in methods for that. I simply want "static" urls to reflect the user's language: /en/projects/internal/project-name /no/prosjekter/interne/prosjektnavn /fr/baguette/champs-elysee/foux-de-fafa Where "projects" is a module, the category "internal" and "project-name" are stored in the database.

  • Subversion terminology. Difference between projects, modules and root directories

    - by aioobe
    I'm setting up a repository for me and some colleagues. I have a subversion repository at hand, and all required rights. The usual directory-skeleton has been set up for me (branches, tags and trunk). Now I'm about to create a directory for me and my colleagues to put our files in. I'm quite sure the right place to put it is in trunk. Now here and there in tutorials, I see terms like "modules" and "projects" such as in Checking Out a Project - svn checkout svn checkout http://host_name/svn_dir/repository_name/project/trunk proj Is proj in the above line some glorified directory in trunk? Should I do something else than a checkout on trunk, mkdir and then commit when creating a directory for me and my colleagues? Whats the difference between a project, a directory in trunk and a module?
