[ANN]: 'tren' Cross-Platform Batch Renaming Tool, Version 1.217 Released And Available
by Tim Daneliuk 23 Apr '10

23 Apr '10

'tren' Version 1.217 is now released and available for download at: http://www.tundraware.com/Software/tren --------------------------------------------------------------------- What's New In This Release? --------------------------- This is the initial public release. What Is 'tren'? ------------------ 'tren' is a general purpose file and directory renaming tool. Unlike commands like 'mv', 'tren' is particularly well suited for renaming *batches* of files and/or directories with a single command line invocation. 'tren' eliminates the tedium of having to script simpler tools to provide higher-level renaming capabilities. 'tren' is also adept at renaming only *part of an existing file or directory name* either based on a literal string or a regular expression pattern. You can replace any single, group, or all instances of a given string in a file or directory name. 'tren' implements the idea of a *renaming token*. These are special names you can embed in your renaming requests that represent things like the file's original name, its length, date of creation, and so on. There are even renaming tokens that will substitute the content of any environment variable or the results of running a program from a shell back into the new file name. 'tren' can automatically generate *sequences* of file names based on their dates, lengths, times within a given date, and so on. In fact, sequences can be generated on the basis of any of the file's 'stat' information. Sequence "numbers" can be ascending or descending and the count can start at any initial value. Counting can take place in one of several internally defined counting "alphabets" (decimal, hex, octal, alpha, etc.) OR you can define your own counting alphabet. This allows you to create sequences in any base (2 or higher please :) using any symbol set for the count. 'tren' is written in pure Python and requires Python version 2.6.x or later. It is known to run on various Unix-like variants (FreeBSD, Linux, MacOS X) as well as Windows. It will also take advantage of 'win32all' Python extensions on a Windows system, if they are present. --------------------------------------------------------------------- Complete details of all fixes, changes, and new features can be found in the WHATSNEW.txt and documentation files included in the distribution. A FreeBSD port has been submitted as well.

colorama : Simple cross-platform colored terminal text.
by Tartley 20 Apr '10

20 Apr '10

ANSI escape character sequences are commonly used to produce colored terminal text on Macs and Unix. Colorama makes these work on Windows too. It works by wrapping stdout and stderr on Windows, with proxies that filter ANSI escape sequences out of printed text, and converting them into equivalent win32 calls. This has the happy side-effect that existing applications or libraries which already use ANSI sequences to produce colored output on Linux or Macs (eg. using packages like 'termcolor') will also work on Windows, simply by calling Colorama.init(). I realise an alternative way to achieve the same result is to install the ANSI.SYS device driver, but it is fiddly and intrusive for the Python developer to do this on their machine of their application's end-user. This is the first release, and while it seems to work for me, no doubt there are still many problems with it. Ruthless feedback is very welcome, about both implementation and philosophy. http://pypi.python.org/pypi/colorama

Announcing virtualenvwrapper 2.1
by Doug Hellmann 18 Apr '10

18 Apr '10

What is virtualenvwrapper ========================= virtualenvwrapper_ is a set of extensions to Ian Bicking's virtualenv_ tool. The extensions include wrappers for creating and deleting virtual environments and otherwise managing your development workflow, making it easier to work on more than one project at a time without introducing conflicts in their dependencies. What's New in 2.1 ================= The primary purpose of this release is a set of enhancements to support virtualenvwrapper.project_, a new extension to manage project work directories with templates. 2.1 also includes several smaller changes and bug fixes. - Add support for ksh. Thanks to Doug Latornell for doing the research on what needed to be changed. - Test import of virtualenvwrapper.hook_loader on startup and report the error in a way that should help the user figure out how to fix it (issue #33). - Update mkvirtualenv documentation to include the fact that a new environment is activated immediately after it is created (issue #30). - Added hooks around cpvirtualenv. - Made deactivation more robust, especially under ksh. - Use Python's ``tempfile`` module for creating temporary filenames safely and portably. - Fix a problem with ``virtualenvwrapper_show_workon_options`` that caused it to show ``*`` as the name of a virtualenv when no environments had yet been created. - Change the hook loader so it can be told to run only a set of named hooks. - Add support for listing the available hooks, to be used in help output of commands like virtualenvwrapper.project's mkproject. - Fix mkvirtualenv -h option behavior. - Change logging so the $WORKON_HOME/hook.log file rotates after 10KiB. .. _virtualenv: http://pypi.python.org/pypi/virtualenv .. _virtualenvwrapper: http://www.doughellmann.com/projects/virtualenvwrapper/ .. _virtualenvwrapper.project: http://www.doughellmann.com/projects/virtualenvwrapper.project/

IPythonQt and IPythonZMQ projects
by Gerardo Gutierrez 17 Apr '10

17 Apr '10

Hi all. I'm writting to tell you about some projects we're developing for you and the entire python programmers community. Read some of the documentation of the proposals and please tell us what are your ideas and what do you want or expect to see of this. I'm going to leave you a summary and some links: *IPythonQt* We will implement a Qt-based Graphical User Interface (GUI) to execute Python code with an interpreter that runs in a separate process and the two systems (GUI frontend and interpreter kernel) communicating via the ZeroMQ Messaging library. The bulk of the implementation will be done without dependencies on IPython (only on Zmq). Once the key features are ready, IPython-specific features can be added using the IPython codebase. *links*: http://ipythonqt.blogspot.com/ https://code.launchpad.net/~ipython-contrib/ipython/qt-frontend *IPythonZMQ* IPython's execution in a command-line environment will be ported to a two process model using the ZeroMQ library for inter-process communication. This will: - prevent an interpreter crash from destroying the user session, - allow multiple clients to interact simultaneously with a single interpreter - allow IPython to reuse code for local execution and distributed computing (DC) - give us a path for Python3 support, since ZeroMQ supports Python3 while Twisted (what we use today for DC) does not. *links*: http://ipythonzmq.blogspot.com/ https://code.launchpad.net/~ipython-contrib/+junk/ipython-zmq Best regards. -- Gerardo Gutiérrez Gutiérrez <http://he1.udea.edu.co/gweb> Physics student Universidad de Antioquia Computational physics and astrophysics group (FACom<http://urania.udea.edu.co/sites/sites.php> ) Computational science and development branch(FACom-dev<http://urania.udea.edu.co/sites/facom-dev/> ) Usuario Linux #492295
