Miros: a hierarchical state machine module
by Tom Schmit 27 Feb '09

27 Feb '09

Miros for Python can be found here: http://www.bellfelljar.org/tractwo/wiki/Python%20Projects. Miros is a module that implements a Hierarchical State Machine (HSM) class (i.e. one that implements behavioral inheritance). It is based on the excellent work of Miro Samek (hence the module name "miros"). This implementation closely follows an older C/C++ implementation published in the 8/00 edition of "Embedded Systems" magazine by Miro Samek and Paul Montgomery under the title "State Oriented Programming". The article and code can be found here: http://www.embedded.com/2000/0008. A wealth of more current information can be found at Miro's well kept site: http://www.state-machine.com/. As far as I know this is the first implementation of Samek's HSM in Python. It was tested with Python 2.5. It is licensed under the same terms as Python itself.

Veusz is a scientific plotting package. It is written in Python, using PyQt4 for display and user-interfaces, and numpy for handling the numeric data. Veusz is designed to produce publication-ready Postscript/PDF output. The user interface aims to be simple, consistent and powerful. Veusz provides a GUI, command line, embedding and scripting interface (based on Python) to its plotting facilities. It also allows for manipulation and editing of datasets. Changes in 1.3: * Add data capture from sockets, files and external programs * Remembers previous entries in dialog boxes * Add shaded regions or lines error bar style * Plot keys can be dragged around with the mouse * New clearer scalable icons * Now requires Python >= 2.4 * minor changes - Add filename completion in several places - Remember import dialog tab selection - Use font drop-down to select font - Add icons for error bar styles - Error bar code rewritten and simplified - Add import dialog to toolbar * bug fixes: - Fix incorrect "security errors" when loading invalid documents - Fix dragging around of shapes and lines problems - Fix address of FSF in license - Fix appearance of dialog box fonts on some systems - Fix recent files menu - Fix hiding of pages and graphs Features of package: * X-Y plots (with errorbars) * Line and function plots * Contour plots * Images (with colour mappings and colorbars) * Stepped plots (for histograms) * Fitting functions to data * Stacked plots and arrays of plots * Plot keys * Plot labels * Shapes and arrows on plots * LaTeX-like formatting for text * EPS/PDF/PNG/SVG export * Scripting interface * Dataset creation/manipulation * Embed Veusz within other programs * Text, CSV and FITS importing Requirements: Python (2.4 or greater required) http://www.python.org/ Qt >= 4.3 (free edition) http://www.trolltech.com/products/qt/ PyQt >= 4.3 (SIP is required to be installed first) http://www.riverbankcomputing.co.uk/pyqt/ http://www.riverbankcomputing.co.uk/sip/ numpy >= 1.0 http://numpy.scipy.org/ Optional: Microsoft Core Fonts (recommended for nice output) http://corefonts.sourceforge.net/ PyFITS >= 1.1 (optional for FITS import) http://www.stsci.edu/resources/software_hardware/pyfits For documentation on using Veusz, see the "Documents" directory. The manual is in pdf, html and text format (generated from docbook). Issues: * Can be very slow to plot large datasets if antialiasing is enabled. Right click on graph and disable antialias to speed up output. If you enjoy using Veusz, I would love to hear from you. Please join the mailing lists at https://gna.org/mail/?group=veusz to discuss new features or if you'd like to contribute code. The latest code can always be found in the SVN repository.

pytemplate: template for python developers
by Stephane Bulot 24 Feb '09

24 Feb '09

Hello, I'm pleased to announce the new release (1.5) of pytemplate project, major step in its young life. pytemplate project is a framework helping python developers at starting their program with a lightweight template, managing basic options like configuration file, logging, daemon capabilities, signal management. I believe that this project is able to help to bring development quality and speed leverage to a lot of small programs. Until a maybe wise introduction in a python release as a built-in module, the best way to use it is to introduce the source file itself in your program. You only have to import the module. You will be able to find usage examples, to download sources at http://www.bulot.org/wiki/doku.php?id=projects:python:pytemplate, wiki page of the project. Do not hesitate to give me your feedback on the concept itself on the program usage, and on its implementation. I would be glad to share this project to improve it. Things that have be done soon: -Windows platform testing (not done). I'm not sure about daemon methodology and signal management. -Python 3 portability. As far as I know, it should not be to much work. Best regards. Stephane
