[ANN] Updated pygments.appspot.com
by zzak 31 Mar '12

31 Mar '12

== An update to pygments.appspot.com http://pygments.appspot.com is an unofficial API for the Pygments syntax highlighting library, which now runs version 1.5. It's designed to provide syntax highlighting for web applications that don't have Python installed. == Usage POST to http://pygments.appspot.com with "lang" and "code" parameters in the body. You'll receive pygmentized HTML back, which you can store for later display on your site. You can style the pygmentized HTML using CSS like this: http://github.com/trevorturk/pygments/blob/master/default.css == Ruby Example $ irb require 'net/http' require 'uri' lang = 'python' code = 'print "Hello World"' request = Net::HTTP.post_form(URI.parse('http:// pygments.appspot.com/'), {'lang'=>lang, 'code'=>code}) puts request.body == Compatibility If your client has issues running an updated version of Pygments, archived releases have been uploaded for your convenience. Simply point the subdomain to the target version of Pygments, like so: http://1-2.pygments.appspot.com/ is configured to run Pygments version 1.2. The following versions are currently supported: 1.2, 1.3, 1.4 and 1.5 == More Information This site was created so that http://flowcoder.com could run on http://heroku.com, but please feel free to use it yourself. If you like, you can fork the code on github and create your own Google App Engine site, though. Visit http://pygments.org/ for more information about Pygments. Visit http://github.com/richleland/pygments-css for more example CSS files for use with Pygments. Visit http://github.com/trevorturk/pygments for more information about this site, and to see the source code. See also: http://www.hilite.me/ for a similar application with more options. == MIT License Copyright (c) 2009-2012 Trevor Turk Zachary Scott Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

ANN: A new version (0.2.9) of the Python module which wraps GnuPG has been released.
by Vinay Sajip 29 Mar '12

29 Mar '12

A new version of the Python module which wraps GnuPG has been released. What Changed? ============= This is a minor bug-fix release. See the project website ( http://code.google.com/p/python-gnupg/ ) for more information. Summary: Better support for status messages from GnuPG. A random data file used in testing is no longer shipped with the source distribution, but created by the test suite if needed. The current version passes all tests on Windows (CPython 2.4, 2.5, 2.6, 3.1, 2.7 and Jython 2.5.1) and Ubuntu (CPython 2.4, 2.5, 2.6, 2.7, 3.0, 3.1, 3.2). On Windows, GnuPG 1.4.11 has been used for the tests. What Does It Do? ================ The gnupg module allows Python programs to make use of the functionality provided by the Gnu Privacy Guard (abbreviated GPG or GnuPG). Using this module, Python programs can encrypt and decrypt data, digitally sign documents and verify digital signatures, manage (generate, list and delete) encryption keys, using proven Public Key Infrastructure (PKI) encryption technology based on OpenPGP. This module is expected to be used with Python versions >= 2.4, as it makes use of the subprocess module which appeared in that version of Python. This module is a newer version derived from earlier work by Andrew Kuchling, Richard Jones and Steve Traugott. A test suite using unittest is included with the source distribution. Simple usage: >>> import gnupg >>> gpg = gnupg.GPG(gnupghome='/path/to/keyring/directory') >>> gpg.list_keys() [{ ... 'fingerprint': 'F819EE7705497D73E3CCEE65197D5DAC68F1AAB2', 'keyid': '197D5DAC68F1AAB2', 'length': '1024', 'type': 'pub', 'uids': ['', 'Gary Gross (A test user) <gary.gr...(a)gamma.com>']}, { ... 'fingerprint': '37F24DD4B918CC264D4F31D60C5FEFA7A921FC4A', 'keyid': '0C5FEFA7A921FC4A', 'length': '1024', ... 'uids': ['', 'Danny Davis (A test user) <danny.da...(a)delta.com>']}] >>> encrypted = gpg.encrypt("Hello, world!", ['0C5FEFA7A921FC4A']) >>> str(encrypted) '-----BEGIN PGP MESSAGE-----\nVersion: GnuPG v1.4.9 (GNU/Linux)\n \nhQIOA/6NHMDTXUwcEAf ... -----END PGP MESSAGE-----\n' >>> decrypted = gpg.decrypt(str(encrypted), passphrase='secret') >>> str(decrypted) 'Hello, world!' >>> signed = gpg.sign("Goodbye, world!", passphrase='secret') >>> verified = gpg.verify(str(signed)) >>> print "Verified" if verified else "Not verified" 'Verified' For more information, visit http://code.google.com/p/python-gnupg/ - as always, your feedback is most welcome (especially bug reports, patches and suggestions for improvement). Enjoy! Cheers Vinay Sajip Red Dove Consultants Ltd.

ANN: Leo 4.10 final released
by Edward K. Ream 29 Mar '12

29 Mar '12

Leo 4.10 final is now available at: http://sourceforge.net/projects/leo/files/Leo/4.10%20final/ Leo is a text editor, data organizer, project manager and much more. http://webpages.charter.net/edreamleo/intro.html Leo 4.10 contains 9 months of intense work on Leo. Several very important features are subtle; you could almost call them Easter Eggs, so please read the following notes carefully. The highlights of Leo 4.10: -------------------------- * Dozens of new and improved features and commands, including... - Tab completion now shows all @command & @button nodes. - Leo tabs may be detached from the main window. - The Open With menu now works. - The leoInspect module answers questions about Python code. - Leo can highlight the pane containing the focus. - The bigdash plugin searches across multiple files. - Improved abbreviation capabilities. - Improved handling of URL's. - Improved editing of non-Leo files. - Improvements create "weightless" unit testing. - Improved Leo's home page. * Easier installation on MacOS. * Fixed almost 70 bugs. The Easter Eggs --------------- 1. Tab completion now shows all @command & @button nodes. Put all your common scripts in @command nodes in myLeoSettings.leo. Typing <Alt-X>@c<Tab> will remind you of the names of these scripts. You can execute the scripts by name without the "@command-" prefix. 2. Improved abbreviation capabilities. Virtually any kind of abbreviation is possible. For example, ~a to ã. 3. Improved handling of URL's. URL's can be used as links to other Leo outlines. 4 Weightless unit testing. The mantra is edit, alt-4 (run-marked-unit-tests-externally), edit, alt-4,... Several seemingly innocuous changes made this work without "friction". The result is a remarkable increase in productivity.

Vulture 0.3 released
by Jendrik Seipp 22 Mar '12

22 Mar '12

vulture - Find dead code ======================== vulture finds unused classes, functions and variables in Python code. This helps you cleanup and find errors in your programs. If you run it on both your library and test suite you can find untested code. Due to Python's dynamic nature it is impossible to find all dead code for a static code analyzer like vulture, because it ignores scopes and scans only token names. Additionally some dynamic items that are not explicitly mentioned in the code may be incorrectly reported as dead code. Download ======== http://pypi.python.org/pypi/vulture Features ======== - Fast: Uses static code analysis - Lightweight: Only one module - Complements pyflakes and has the same output syntax - Supports Python 2.6, 2.7 and 3.x News ==== * Add support for python3 * Report unused attributes * Find tuple assignments in comprehensions * Scan files given on the command line even if they don't end with .py Cheers, Jendrik

pysandbox 1.5 released
by Victor Stinner 20 Mar '12

20 Mar '12

pysandbox is a Python sandbox. By default, untrusted code executed in the sandbox cannot modify the environment (write a file, use print or import a module). But you can configure the sandbox to choose exactly which features are allowed or not, e.g. import sys module and read /etc/issue file. http://pypi.python.org/pypi/pysandbox https://github.com/haypo/pysandbox/ Main changes since pysandbox 1.0.3: - More modules and functions are allowed: math, random and time modules, and the compile() builtin function for example - Drop the timeout feature: it was not effective on CPU intensive functions implemented in C - (Read the ChangeLog to see all changes.) pysandbox has known limitations: - it is unable to limit memory or CPU - it does not protect against bugs (e.g. crash) or vulnerabilities in CPython - dict methods able to modify a dict (e.g. dict.update) are disabled to protect the sandbox namespace, but dict[key]=value is still accepted It is recommanded to run untrusted code in a subprocess to workaround these limitations. pysandbox doesn't provide an helper yet. pysandbox is used by an IRC bot (fschfsch) to evaluate a Python expression. The bot uses fork() and setrlimit() to limit memory and to implement a timeout. https://github.com/haypo/pysandbox/wiki/fschfsch -- The limitation on dict methods is required to deny the modification of the __builtins__ dictionary. I proposed the PEP 416 (frozendict) but Guido van Rossum is going to reject it. I don't see how to fix this limitation without modifying CPython. http://www.python.org/dev/peps/pep-0416/ Victor
