Python documentation: news sphinx/numpydoc + flexirest + sphinx sourceforge theme/{gsdview,bestgui}

Posté par patrick le novembre 16, 2009

- http://pypi.python.org/pypi/numpydoc/0.3.1 (Sphinx extension to support docstrings in Numpy format)

- http://pypi.python.org/pypi/flexirest/ (‘ The medium-featured, flexible reStructuredText utility. Flexirest is a project that was born out of the authors long-running interest for reStructuredText, and the idea of writing everyday documents like letters, invoices and other simple documents in this way. Flexirest tries to strike a middle ground between docutils own command line tool chain (rst2html et al), that I find a little to minimalistic and Sphinx, that I find very nice but a little heavy to use for a quickie document like a random letter or some such. In short, the goal of flexirest is to enable you to use the reST format for everyday documents instead of a word processor or similar with minimal fuzz. Hence you get to stay in the comfy environment of your text editor and tool chain. And you can check in your docs in text format into your version control system of choice. And, if used correctly, you get to reuse a couple of stylings that you only need to create once. There are some modestly advanced tricks you can do too, primarily writing your own docutils roles, but I wouldn’t consider those the major points of flexirest. For more information on how to operate flexirest, see the quick manual.’)

Python : documentation technique de projets logiciels : un article de Jacob Kaplan-Moss (partie 1) / Django / sphinx

Posté par patrick le novembre 12, 2009

Source: http://jacobian.org/writing/great-documentation/what-to-write/

Voici quelques extraits intéressants:

I love Django’s documentation. It clocks in at about 700 pages printed, and most of it is clear, concise, and helpful. I think Django’s among the best documented open source projects, and nothing makes me prouder.


Today I’ll discuss the different forms technical documentation can take, and where to focus your efforts.

 

Tutorials

Good tutorials are a must as they’re usually the first thing someone sees when trying out a new piece of tech. First impressions are incredibly important: that rush of success as you work through a good tutorial will likely color your future opinions about the project….Be quick. At some conference or another I heard someone — I think it was Kathy Sierra — say that, as a rule of thumb, a new user should be able to experience success within thirty minutes…

Topical guides

This is the meat of your documentation. Once somebody’s learned (from a tutorial) the high-level concepts, they’re going to need to dive into the details of some area or another. Any documentation worth its salt is going to have a whole bunch of these — Django’s got about 35 different topical guides, covering each conceptual area (e.g. models, sessions, testing, etc.)…The main goal for topical coverage should be comprehensiveness. The reader ought to come away from a close read feeling very comfortable with the topic in question. They should feel that they know the vast majority of the possible options, and more importantly they should understand how all the concepts fit together.

Unfortunately there aren’t a lot of projects that do these very well. Most have reasonable tutorials, many have okay-to-good reference material, but most seem to leave the topical guides to books.

 

Reference

Finally, you need complete reference for all the public APIs your project provides. These should be designed for those who already know how to use some API, but need to look up the exact arguments some function takes, or how a particular setting influences behavior, etc…It’s important to point out that reference material is not in any way a substitute for good tutorials and guides!..Think of guides and reference as partners: guides give you the “why,” and reference gives you the “how.”

It’s really tempting to use an auto-documentation tool like Javadoc or RDoc for reference material.

Don’t.

Auto-generated documentation is almost worthless. At best it’s a slightly improved version of simply browsing through the source, but most of the time it’s easier just to read the source than to navigate the bullshit that these autodoc tools produce. About the only thing auto-generated documentation is good for is filling printed pages when contracts dictate delivery of a certain number of pages of documentation. I feel a particularly deep form of rage every time I click on a “documentation” link and see auto-generated documentation.

There’s no substitute for documentation written, organized, and edited by hand.

I’ll even go further and say that auto-generated documentation is worse than useless: it lets maintainers fool themselves into thinking they have documentation, thus putting off actually writing good reference by hand. If you don’t have documentation just admit to it. Maybe a volunteer will offer to write some! But don’t lie and give me that auto-documentation crap.

On behalf of the Distribute team, I am pleased to announce the 0.6.7
release of Distribute.

As usual, availabe at PyPI: http://pypi.python.org/pypi/distribute

Most noticeable changes in 0.6.7 are:

- now the develop command supports the --user option, so it can use
the per-user site packages (PEP 370)
- the generated scripts now wrap their call to the script entry point
in the standard "if name == 'main'"
- better errors handling in PackageIndex when files and pages are
visited by easy_install
- a virtualenv-compatible version, so the next virtualenv release will
be able to provide a --distribute option.

You can visit http://pypi.python.org/pypi/distribute#id2 for a full
CHANGES list.

We are now starting the 0.6.8 work in parallel of 0.7.x development,
with more bugfixes coming up.

Des nouvelles de python : Guido Van Rossum et la documentation avec sphinx/rest , numpy, scipy, ipython

Guido Van Rossum

- http://neopythonic.blogspot.com/2009/11/python-in-scientific-world.html (‘...After the meeting, Fernando showed me a little about how NumPy is maintained. They have elaborate docstrings that are marked up with a (very light) variant of Sphynx, and they let the user community edit the docstrings through a structured wiki-like setup. Such changes are then presented to the developers for review, and can be incorporated into the code base with minimal effort.

An important aspect of this approach is that the users who edit the docstrings are often scientists who understand the computation being carried out in its scientific context, and who share their knowledge about the code and its background and limitations with other scientists who might be using the same code. This process, together with the facilities in IPython for quickly calling up the docstring for any object, really improves the value of the docstrings for the community. Maybe we could use something like this for the Python standard library; it might be a way that would allow non-programmers to help contribute to the Python project (one of the ideas also mentioned in the diversity discussions).’)
- http://fdoperez.blogspot.com/2009/11/guido-van-rossum-at-uc-berkeleys.html (‘…I wanted both to thank him for creating and shepherding such a high-quality language for us scientists, and to establish a good line of communication with him (and indirectly the core python development group) so that he can understand better what are some of the use patterns, concerns and questions we may have regarding the language.I have the impression that in this we were successful, especially as we had time after the open presentations for a more detailed discussion of how we use and develop our tools. Most of us in scientific computing end up spending an enormous amount of time with open interpreter sessions, typically IPython ones (I started the project in the first place because I wanted a very good interactive environment, beyond Python’s default one), and in this work mode the key source of understanding for code are good docstrings. This is an area where I’ve always been unhappy about the standard library, whose docstrings are typically not very good (and often they are non-existent). We showed Guido the fabulous Numpy/Scipy docstring editor by Pauli Virtanen and Emmanuelle Gouillart, as well as the fact that Numpy has an actual docstring standard that is easy to read yet fairly complete. I hope that this may lead in the future to an increase in the quality of the Python docstrings, and perhaps even to the adoption of a more detailed docstring standard as part of PEP 8, which I think would be very beneficial to the community at large…’)A voir:

fOSSa

 

Date: November 17-18, 2009
Venue: World Trade Center, Grenoble, France
Practical information, detailed program and registration: http://fossa.inrialpes.fr/2009/

Conference overview
The “fOSSa” conference (Free/Open Source Software Academics) is co-organised by INRIA and OW2 Europe Local Chapter. It will review Open Source fundamentals and will present innovating Open Source project as well as communities experiences. fOSSa is the first international Open Source Conference event located in Grenoble! The fOSSa audience mainly focuses on academia and research centres but does not close the door to industrials as in many cases academia needs industrials and vice versa: we believe that Open Source model can improve such kind of collaboration in a much more natural way.

DAY 1 is focusing on the Open Source model basics:

1. OSS and Benefits for Academic projects
2. OSS and Innovation for Academic projects
3. OSS and Business Models for Academic projects
4. OSS and the Law for Academic projects
5. OSS and Communities for Academic projects
6. OSS and European Commission fo Academic projects
7. OSS and Market Needs for Academic projects

DAY 2, practical session including with real life examples of the OSS fundamentals, will address:

1. OSS and Collaboration for Academic projects
2. OSS and Promotion for Academic projects
3. OSS and Governance for Academic projects
4. OSS and Quality for Academic projects
5. OSS and the Law for Academic projects

Day 2, 10-10-10 presentation

In parallel, OW2 academic projects will be presented in a 10-10-10 formula style1. PLUMES/FEATHER community will present scientific Open Source academic projects, and sessions will be booked for Open Source Start-up’s presentation.

(1) 10 minutes presentation -10 minutes demo -10 minutes questions/answers.

Participants
Apache, Eclipse, Engineering, HP Fossology, INRIA, Mandriva, OW2, Sun Microsystem, University Paris VII, University of Milano…

fOSSa (Free Open Source Software for Academia) est organisée conjointement par le chapitre local Europe d’OW2 et l’INRIA.

L’histoire du logiciel libre débute dans les années 70 grâce aux universitaires et chercheurs académiques: pour cette communauté, distribuer un code informatique sous une licence permissive était une règle naturelle. Depuis, le monde du logiciel libre connaît un succès extraordinaire à travers, en outre, le monde industriel. Cependant, les objectifs initiaux défini par le monde académique semble, aujourd’hui, être oubliés.

Le programme couvre les aspects fondamentaux du logiciel libre/open-source (modèles économiques, licences, collaboration, communautés, promotion, exploitation) et propose des retours d’expérience ainsi que des présentations de projets innovants.  Elle s’adresse au monde académique/universitaire, mais aussi aux industriels dans la mesure où les relations recherche/industrie sont de plus en plus souvent au coeur de développements collaboratifs libres/open-source: fOSSa propose de repositionner le Libre au centre des collaborations recherche-industrie.

Les intervenants sont, en autre, Clément Escoffier (Apache), Ralph Mueller (Directeur Fondation Eclipse Europe), HP Fossology (Bob Gobeille et Bruno Cornec), INRIA (Luc Grateau et Jean Bernard Stefani), Arnaud Laprévote (Directeur R&D Mandriva), Cédric Thomas (OW2 Consortium CEO), Roberto Di Cosmo (CIRILL & Mancoozi), Plumes (Jean Luc Archimbaud et Teresa Gomez DIaz) …

Documentation de python 2.6 grâce à sphinx

Posté par patrick le octobre 27, 2009

L’utilisation de sphinx pour la documentation python faisait partie des nouveautés de la version 2.6.1 sortie le 1er octobre 2008.

- http://docs.python.org/whatsnew/2.6.html

New Documentation Format: reStructuredText Using Sphinx

The Python documentation was written using LaTeX since the project started around 1989. In the 1980s and early 1990s, most documentation was printed out for later study, not viewed online. LaTeX was widely used because it provided attractive printed output while remaining straightforward to write once the basic rules of the markup were learned.

Today LaTeX is still used for writing publications destined for printing, but the landscape for programming tools has shifted. We no longer print out reams of documentation; instead, we browse through it online and HTML has become the most important format to support. Unfortunately, converting LaTeX to HTML is fairly complicated and Fred L. Drake Jr., the long-time Python documentation editor, spent a lot of time maintaining the conversion process. Occasionally people would suggest converting the documentation into SGML and later XML, but performing a good conversion is a major task and no one ever committed the time required to finish the job.

During the 2.6 development cycle, Georg Brandl put a lot of effort into building a new toolchain for processing the documentation. The resulting package is called Sphinx, and is available from http://sphinx.pocoo.org/.

Sphinx concentrates on HTML output, producing attractively styled and modern HTML; printed output is still supported through conversion to LaTeX. The input format is reStructuredText, a markup syntax supporting custom extensions and directives that is commonly used in the Python community.

Sphinx is a standalone package that can be used for writing, and almost two dozen other projects (listed on the Sphinx web site) have adopted Sphinx as their documentation tool.

Les projets python de la semaine 37: Tornado (web) , sqlkit (database), HeeChee (mercurial-subversion), sinthgunt (video, ffmpeg)

Posté par patrick le septembre 12, 2009

  • http://www.tornadoweb.org/ (‘Tornado is an open source version of the scalable, non-blocking web server and tools that power FriendFeed. The FriendFeed application is written using a web framework that looks a bit like web.py or Google’s webapp, but with additional tools and optimizations to take advantage of the underlying non-blocking infrastructure. The framework is distinct from most mainstream web server frameworks (and certainly most Python frameworks) because it is non-blocking and reasonably fast. Because it is non-blocking and uses epoll, it can handle thousands of simultaneous standing connections, which means it is ideal for real-time web services. We built the web server specifically to handle FriendFeed’s real-time features — every active user of FriendFeed maintains an open connection to the FriendFeed servers. (For more information on scaling servers to support thousands of clients, see The C10K problem…Tornado has been tested on Python 2.5 and 2.6. To use all of the features of Tornado, you need to have PycURLsimplejson installed and a JSON library like )’)
  • http://www.aeracode.org/2009/9/10/announcing-heechee/ (…One of the particular issues I have is with svn:externals. A lot of apps – including some we have at work – rely on svn:externals to pull in external dependencies into a libs folder along with the project itself. Externals is one of the few features of subversion that I thought was pretty much perfect, and it was sad to see my move to Mercurial break itOne of the questions led him onto hg-git – the awesome git backend plugin for Mercurial, that the GitHub guys wrote – and how they first investigated the idea of an svn gateway to expose their repositories transparently to subversion users. From what I gathered, subversion’s wire format proved too tricky to deal with, and so they turned elsewhere…After some digging, reading an obscure academic paper and liberal application of Wireshark, I grew confident enough that I could at least implement something. A day later, and I’d like to present the very first version of what I’m calling Heechee (if you get the pun, ten nerd points). Heechee is a transparent mercurial-as-subversion gateway. It serves a Mercurial repository as a Subversion WebDAV-based repository. It’s still in the early stages, but at the moment it will serve its own mercurial repository to subversion in such a way that you can check out the repository, and update to various revisions within it.You can check it out at BitBucket. It’s pretty alpha code, and make sure you have the dependencies mentioned in the README, but it works, which greatly surprises me. I plan to much improve the code to support more ‘advanced’ features, like being able to do more than checkout and update, as well as exposing tags and branches correctly. There’s even the chance I’ll stick Git support in, when I’ve had a play with Dulwich.)
