Translating Sphinx documentation

Few days ago, I've started writing Odorik module to manipulate with API of one Czech mobile network operator. As usual, the code comes with documentation written in English. Given that vast majority of users are Czech, it sounds useful to have in Czech language as well.

The documentation itself is written in Sphinx and built using Read the Docs. Using those to translate the documentation is quite easy.

First step is to add necessary configuration to the Sphinx project as described in their Internationalization Quick Guide. It's matter of few configuration directives and invoking of sphinx-intl and the result can be like this commit.

Once the code in repository is ready, you can start building translated documentation on the Read the docs. There is nice guide for that as well. All you need to do is to create another project, set it's language and link it from master project as translation.

The last step is to find some translators to actually translate the document. For me the obvious choice was using Weblate, so the translation is now on Hosted Weblate. The mass import of several po files can be done by import_project management command.

And thanks to all these you can now read Czech documentation for python Odorik module.

Odorik modul 0.4

Dnes jsem vydal novou verzi Python modulu Odorik. Přidává spoustu užitečných vlastností pro zjištění stavu účtu.

Jako bonus k tomuto vydání je dokumentace přeložená do češtiny za použití Weblate.

Python modul pro Odorik

Pokud náhodou použáváte operátora Odorik, mohl by se vám hodit můj nový modul pro Python. Dokonce ani nemusíte umět Python, dá se použít i přímo z příkazové řádky.

Funkčnost je zatím velmi jednoduchá, ale čase určitě přibudou další užitečné funkce (nebojte se mi nahlásit nápady).

python-gammu 2.2

After recent porting python-gammu to Python 3, it was quite obvious to me that new release will have some problems. Fortunately they have proven to be rather cosmetic and no big bugs were found so far.

Anyway it's time to push the minor fixes to the users, so here comes python-gammu 2.2. As you can see, the changes are pretty small, but given that I don't expect much development in the future, it's good to release them early.

This was Sri Lanka

We've spent beautiful weeks on Sri Lanka in January and February. On the way we've seen many different places - ancient cities, mountains, natural parks or beaches. Here comes selection of photos which I like most.

Packaging python-gammu

After Monday release of separate Gammu and python-gammu, the obvious task was to get the new package to distributions.

First I've started with Debian packages, what was quite easy as from quite complex CMake + Python package it is now purely CMake and it was mostly about removing stuff. Soon the updated Gammu package was uploaded to experimental. Once having that ready, I've also update the backports for Ubuntu and these are available in Gammu PPA. Creating new python-gammu package was a bit harder as this is the first Python 3 compatible package I've created, but it's now ready and sitting in the NEW queue.

While working on python-gammu package, I've realized that some of the data used in testsuite are missing in the tarball. While not being critical, this is definitely not nice, so I've decided to release python-gammu 2.1 today. It also includes fixes for some corner cases found by coverity.

For openSUSE the packaging was quite easy as well, stripping out unneeded parts of Gammu package went smoothly and it's now in hardware project, SR to Factory is pending. With python-gammu it turned out to be much harder as the testsuite had failed there with some strange error coming out of libdbi. After looking deeper into it, the problem is in new return type available in Git snapshot openSUSE is shipping. Fortunately producing fix was quite easy, so next Gammu upstream will handle that properly and package in hardware project is already patched. You can now use python-python-gammu from devel:languages:python and SR to Factory is pending as well.

Hacking Gammu

I've spent first day of SUSE Hackweek on Gammu. There are quite many tasks to be done and I wanted to complete at least some of them.

First I started with the website. I did not really like the old layout and aggressive colors and while touching it's code it's good idea to make the website work well in mobile devices. I've started with conversion to Bootstrap and It turned out to be quite easy task. The next step was making the pages simpler as in many places there was too much information hidden in sidebar. While doing content cleanup, I've removed some features which really don't make much sense these days (such as mirror selection). Anyway read more in the news entry on the site itself.

Second big task was to add support for Python 3 in python-gammu. It seems that world is finally slowly moving towards Python 3 and people started to request python-gammu to be available there as well. The porting itself took quite some time, but I've mostly completed it before Hackweek. Yesterday, there was just some time spent on polishing and releasing standalone python-gammu and Gammu without python bindings. Now you can build python-gammu using distutils or install it using pip install python-gammu.

GSoC 2015 applications for phpMyAdmin

As usual, I look at the application stats for phpMyAdmin just after student application period of Google Summer of Code is over.

First of all we got way more proposals than in last years, but also number of bogus proposals went up (you can see them as ignored in the chart).

Same as in past years, people leave the submission to the last moment, even though we encourage them to submit early so that they can adjust the application based on our feedback. But still we got more than half of the proposals in last three days.

Number of applications over time

Anyway we're just working on evaluation and will finalize it in upcoming days. Of course you will know the results from Google on April 27th.

PS: You can compare to our 2014, 2013 and 2012 numbers.

Porting python-gammu to Python 3

Over the time I started to get more and more requests to have python-gammu working with Python 3. Of course this request makes sense, but I somehow failed to find time for that.

Also for quite some time python-gammu has been distributed together with Gammu sources. This was another struggle to overcome when supporting Python 3 as in many cases users will want to build the module for both Python 2 and 3 (at least most distributions will want to do so) and with current CMake based build system this did not seem to be easy to achieve.

So I've decided it's time to split python module out of the library. The reasons for having that together are no longer valid (libGammu has quite stable API these days) and having standard module which can be installed by pip is a nice thing.

Once the code has been put into separate git module, I've slowly progressed on porting to Python 3. Most of the problems were on the C side of the code, where Python really does not make it easy to support both Python 2 and 3. So the code ended up with many #ifdefs, but I see no other way. While doing these changes, many points in the API were fixed to accept unicode stings in Python 2 as well.

Anyway, today we have first successful build of python-gammu working on both Python 2 and 3. I'm afraid there is still some bug leading to occasional segfaults on Travis, but not reproducible locally. But hopefully this will be fixed in upcoming weeks and we can release separate python-gammu module again.
