rst2pdf 0.10
by ralsina＠netmanagers.com.ar May 15, 2009

May 15, 2009

It's my pleasure to announce the release of rst2pdf version 0.10. This version includes many bugfixes and some new features compared to the previous 0.9 version. Rst2pdf is a tool to generate PDF files directly from restructured text sources via reportlab. It aims to support the full restructured text feature set, and is very close to that goal, while also including some of the more experimental features, like a source code directive with syntax highlighting and math notation support with LaTeX-like syntax. It supports embedding arbitrary fonts, both True Type and PS Type 1, both raster and vector images (including SVG), page transition effects, multiple, flexible page layouts, cascading styles, and much, much more. You can find more information about rst2pdf in its home page ( http://rst2pdf.googlecode.com), and ask anything you want in the rst2pdf- discuss mailing list (http://groups.google.com/group/rst2pdf-discuss) Here are the changes in this version compared to 0.9: * Issue 87: Table headers can be repeated in each page (thanks to Yasushi Masuda) * Issue 93: Line number support for code blocks (:linenos: true) * Issue 111: Added --no-footnote-backlinks option * Issue 107: Support localized directives/roles (example: sommaire instead of contents) * Issue 112: Fixed crash when processing empty list items * Issue 98: Nobreak support, and set as default for inline-literals so they don't hyphenate. * Slightly better tests * Background colors in text styles work with reportlab 2.3 * Issue 99: Fixed hyphenation in headers/footers (requires wordaxe 0.3.2) * Issue 106: Crash on demo.txt fixed (requires wordxe 0.3.2) * Issue 102: Implemented styles for bulleted and numbered lists * Issue 38: Default headers/footers via options, config file or stylesheet * Issue 88: Implemented much better book-style TOCs * Issue 100: Fixed bug with headers/footers and Reportlab 2.3 * Issue 95: Fixed bug with indented tables * Issue 89: Implemented --version * Issue 84: Fixed bug with relative include paths * Issue 85: Fixed bug with table cell styles * Issue 83: Fixed bug with numeric colors in backColor attribute * Issue 44: Support for stdin and stdout * Issue 79: Added --stylesheet-path option * Issue 80: Send warnings to stderr, not stdout * Issue 66: Implemented "smart quotes" * Issue 77: Work around missing matplotlib * Proper translation of labels (such as "Author", "Version" etc.) using the docutils languages package. (r473) * Fixed problems with wrong or non-existing fonts. (r484) * Page transition effect support for presentations (r423) I hope you enjoy this software!

[ANN] Introduction to Python course, San Francisco, Jun 2009
by wesley chun May 14, 2009

May 14, 2009

Need to get up-to-speed with Python as quickly as possible? Come join me, Wesley Chun, author of Prentice-Hall's bestseller "Core Python Programming," for a comprehensive intro course coming up this June in beautiful Northern California! Please pass on this note to whomever you think may be interested. I look forward to meeting you and your colleagues! (Comprehensive) Introduction to Python Mon-Wed, 2009 Jun 15-17, 9am-5pm - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - (COMPREHENSIVE) INTRODUCTION TO PYTHON Although this course may appear to those new to Python, it is also perfect for those who have tinkered with it and want to "fill in the gaps" and/or want to get more in-depth formal training. It combines the best of both an introduction to the language as well as a "Python Internals" training course. We will immerse you in the world of Python in only a few days, showing you more than just its syntax (which you don't really need a book to learn, right?). Knowing more about how Python works under the covers, including the relationship between data objects and memory management, will make you a much more effective Python programmer coming out of the gate. 3 hands-on labs each day will help hammer the concepts home. Come find out why Google, Yahoo!, Disney, ILM/LucasFilm, VMware, NASA, Ubuntu, YouTube, Slide, and Red Hat all use Python. Users supporting or jumping to Plone, Zope, TurboGears, Pylons, Django, Google App Engine, Jython, IronPython, and Mailman will also benefit! FREE PREVIEW 1: you will find (and can download) a video clip of a live lesson that was delivered recently to get an idea of the lecture style and interactive classroom environment at: http://cyberwebconsulting.com (click "Python Training") FREE PREVIEW 2: Partnering with O'Reilly and Pearson, Safari Books Online has asked me to deliver a 1-hour webcast on Wednesday morning 2009 Apr 29 @ 10:30a PDT/1:30p EDT called "What is Python?" This will be an online seminar based on a session that I've delivered at numerous conferences in the past. It will give you an idea of lecture style as well as an overview of the material covered in the course. Plus the first 10 registrants will receive an autographed copy of "Core Python Programming!"

Regular Toronto Python Users' Group (PyGTA) meeting Tuesday 19th, 7:15pm
by Mike C. Fletcher May 13, 2009

May 13, 2009

We will be having our regular PyGTA meeting at our regular time (7:15 on the 19th) and place (Linux Caffe) this month. Please note that *next* month (June 2009) we'll be meeting on the 17th (a Wednesday) as our speaker for June is not available on Tuesdays. Linux Caffe is at the corner of Grace and Harbord streets, 1 block South of Christie subway station. Tuesday, May 19th: Software Liability Round Table (Open Discussion) Proposals are afoot in the EU to make companies liable for the software they write. What would you need to accept liability for the software you write? Would you be willing to contribute software to an Open Source project if you could be sued when someone else broke it? What level of warranty would you be willing to give for your software ("Money Back" or "Damages" or "Damages and Loss of Bussiness")? Is liability even a good idea? Would it stifle innovation? Would it be workable for your business? What benefits would you get out of warranties? Is there a service or testing methodology you feel would let you provide warranties better/cheaper/faster than others? Would an exception raised to the user constitute a "money back" event? Or would you have to fail to repair the software? Does "repairing" include making your software work with changing dependencies? What contracts or requirements would you need to be comfortable being a contract software developer? Wednesday, June 17th: Behdad Esfahbod will be presenting on how to use the Cairo rendering library from Python. Cairo is a vector graphics library that allows for targetting multiple graphical back-ends including OpenGL, X-windows, OSX Quartz, Win32, PDF, PNG etceteras. It is used in the Firefox and WebKit engines as well as the GTK library. Note the change in day-of-week! Tuesday, July 21st (tentative): Robert Jackiewicz of the Toronto Plone User's group will be presenting the zc.buildout package. Buildout is a tool for creating redistributable Python applications which is used extensively by the Zope and Plone communities. It is a "recipe" based engine for reproducing a set of modules and application code onto a number of machines. http://www.pygta.org/ Enjoy yourselves, Mike -- ________________________________________________ Mike C.

May 11, 2009

Minutes after RC1 we had to do an RC2 due to a bug in our build process + JLine. RC2 is here: http://downloads.sourceforge.net/jython/jython_installer-2.5rc2.jar And Moss Prescott pointed out that the URL was wrong for install instructions. The correct url for installation is: http://www.jython.org/Project/installation.html. -Frank

Jython 2.5.0 Release Candidate 1 is out!
by Frank Wierzbicki May 11, 2009

May 11, 2009

On behalf of the Jython development team, I'm pleased to announce that Jython 2.5rc1 is available for download at http://downloads.sourceforge.net/jython/jython_installer-2.5rc1.jar. See the installation instructions: http://www.jython.org/Project/installation.htm. It contains bug fixes and polish since the last beta. One especially nice bit of polish is that JLine (http://jline.sourceforge.net) is enabled by default now, and so using up and down arrows should work out of the box. If no major bugs are found this release will get re-labeled and released as the production version of 2.5.0. Please try this out and report any bugs that you find: http://bugs.jython.org. -Frank
