Yesterday I saw an entry in Juanjo’s blog talking about the book he started to learn programming with. And immediately I decided I had to look for my own start book.
It was when I was 7 years old, and my parents gave us an MSX computer (a Toshiba HX-10). One month later my father decided he wanted to implement software for his business (he’s got a clinic laboratory), and bought a very big book, MSX, Guía del programador y manual de referencia (The Complete MSX Programmers Guide, by T.Sato, P.Mapstone and I.Muriel, 1984).
It was the beginning. Since them my life was heavily tied to computer science. I’ve played many games in computers, written a lot of documents, pictures or even music. But the start was a BASIC program. This year I’ve done 20 years programming.
Once upon a time, there was gtk-doc. It was weird and strange, and overall, different from other standards like javadoc or doxygen. But we gnomish people, were tied to it, as it was the only one working correctly with GtkObject/GObject. It’s still this way, as I don’t know any good solution with Doxygen or other tool to fill the space of gtk-doc.
Why it was weird? For me, the worst point was the need to maintain a set of files called templates. They were docbook templates that covered some documentation that you couldn’t add to your source code. These files were processed by some scripts that didn’t work very well with version control systems.
With gtk-doc 1.5 we can avoid the templates, at least for most of the use cases they were required. Now you can add to the source code a commentary like this one:
* @short_description: This is my short description for #MyClassName
* @see_also: #Other, #AnyOtherOne
* It's a long description about this and that, and other things. You can write
* about many things and enter sgml tags like:
* <itemizedlist><listitem>an itemized list</listitem><itemizedlist>
With this structure you remove at last the templates requirement. One additional note. As there was a bug in gtk-doc 1.5, the general makefile scripts provided don’t work with no templates. You have to add a rule to the documentation Makefile.am like this:
Another interesting point is using gtk-doc.make. It’s a script provided by the gtk-doc distribution providing general structure for gtk-doc processing. You can use it adding this line to the Makefile.am:
For all of you folks that always complain about how difficult it is to create latex documents with those complex Makefiles compiling figures, linking eps’s, doing bad works to generate pdf or ps automatically, latex-make is here.
It’s a makefile include file to help you compile and track dependencies of a latex document. For example, if you want to compile a latex-only document (of one or more files), you only have to create a Makefile with one line. Imagine the master tex file is called mydocument.tex. Then you would write a Makefile with two lines like this:
If you want to state which kind of outputs you want it to compile by default, you only have to state the flavors (PS, DVIPDF and/or PDF):
And about the figures. If you have the figures of your document in figures directory, you only have to add:
There are more interesting points. It adds a module to handle .fig files and bibliographies.
This week I’ve been hacking a while around Dogtail. It’s a Python library intended for implementation of functional tests of applications providing accessibility support through AT-SPI. It lets you check and manipulate the user interface from Python scripts, and it’s easy to integrate it into test cases.
While I was working, I found that I could not easily browse tabs in a GtkNotebook using dogtail. This issue has been reported in Gnome bugzilla (bug report). The problem is:
- Dogtail uses Python SPI bindings (in project pyspi) to access the accessibility layer. This bindings are a direct wrapper over CSPI.
- GtkNotebook accessibility implementation has the page tab list role, and the tabs have the page tab role. The notebook exposes the currently selected tab through the Selection interface. It lets you specify a selection of children of an accessible container.
- Unfortunately neither Python SPI bindings nor Dogtail provide support for this. Then it’s not easy to change the currently active tab of a notebook.
I’m not the only one that has detected the problem this way. Peter Johanson has sent two bugs and patches to solve the issue and add tab browsing support in Dogtail (report in Pyspi and report in Dogtail). In parallel I was developing similar patches. As Peter Johansons’ are more complete, I’ve simply added some functionalities this morning to the dogtail patch to provide an easier way to use the selection interface in Dogtail. I’ve uploaded the new patch to the Dogtail bug report.
Now you can simply write:
focus.widget(roleName='page tab', name='My tab')
And it raises the desired tab easily. Hope those patches go upstream. I think they're a good solution for the tab browsing issue.
Some time ago, in the Guadec-es in Coruña, there was an interesting meeting to talk about interesting enhancement in Gnome desktop. It was mainly centered in i18n issues, but I talked about the way other platforms work in network APIs.
Briefly, I missed a way to know about network status and manage connections, as other platforms do (for example, we get this kind of API in Microsoft Windows related SDK with Connection Manager API. The same applies to power management.
But now there’s an interesting work to face this issue. If Network manager and Power manager DBUS message providers get more or less standarised in Linux distros, we’ll get an standard API to do this kind of use cases:
- Know if we’re connected to the internet
- Bring up the default network connection to the internet if it’s shut down. (Useful for devices like palms or mobile phones or even PC’s with analog modem internet). Maybe with a standard dialog in Gnome.
- Some knowledge about the network status.
- Know if the PC or device is plugged, and then decide if our application wants to save power or not.
It seems these managers, and their use of DBUS, are the way to go. Good luck!
Long time since last time I’ve written here. I’ve been sick some days, trying to work in some stuff. I’ve got my midterm exams in Escuela Oficial de Idiomas (State Language School). I’m doing the 5th degree of English (the last one) here in Vigo. Seems they were good exams. The bad point was the writing exam, which was based on a Lost episode I haven’t seen (7th of the second season). Fortunately it seems it didn’t contain any spoilers.
Last weeks I went to two concerts of local groups. The first was in El Ensanche (Vigo), and was performed by Iván Ferreiro, with the collaboration of Xoel. They performed as Rai Doriva e as Ferreiro, playing classic songs as Inbetween days by The Cure, some songs from Andrés Calamaro and so on. Good to see them again.
And yesterday I went to a concert of Heissel in Pub Aturuxo (Bueu). Second time I’ve seen them, and again, interesting. This time we talked a bit with some members of the group. They’ve just released their first recording El lugar más feliz(Happiest place).
Last week Gnome 2.12 has finally hit completely Debian Sid. Big improvement Rhythmbox to my music player. Libnotify popups, queued-to-play songs UI management and other things. Congratulations to developers!
In this week release of Debian Weekly News there’s a request for help from Debian GNOME team. You can see a list of required tasks from Alioth.
Maybe an oportunity for you folks, if you want to help in such an important task.
Hi guys. Here in Igalia many of us are starting to blog. So welcome to this area!
