Firstly I developed preliminary versions of syntax highlighting and tab complete features. This version use XML file processing to provide a basic set of keywords and built-in functions to these features. To activate tab complete, press Tab button after some letter. You can see some screenshots of these features below (click mouse right-button and enlarge it):
A simple syntax highlighting
More syntax highlighting and tab complete
Next, the preliminary version of the backend developed during LaKademy was build to support python script mode. But it would be more interesting to support python interactive mode in Cantor console. So, to do it, I implemented preprocessing in python command before send it to python interpreter, adding some commands to simulate python interactive mode.
This solution use PyRun_SimpleString from python/C API to process python commands in python script mode. There is other functions from python/C API to process python commands in interactive mode, for example, PyRun_InteractiveOne, but this function requires the python commands in a file to process and the output of commands is a bit of hard to get. So, for now, PyRun_SimpleString + preprocessing commands is working very well.
You can see in screenshots below and above that variable values and operation values are show in Cantor console without use of print command. It is a one of characteristic of python interactive mode:
More examples of syntax highlighting and python interactive mode
Now I am developing a feature to list all functions and keywords from a specific python module imported during the program execution. I am using dir command to do it. This feature will provide these keywords to use in syntax highlighting and tab complete in a dynamic way. Then, python backend will support any python module, and not scipy, numpy, and matplotlib only.
Python backend is available in python-backend branch in Cantor repository. You can test it, but remember this code is not stable and finalized for now.
This year I have a project accepted to Google Summer of Code. This is my second time in the program and I am very happy and grateful for it
This year I come back to Cantor, the KDE mathematical environment for several mathematical softwares like Maxima, Sage, Scilab, etc. In 2011 I developed the Scilab backend during Google Summer of Code. My mentor was Sylvestre Ledru, from Scilab team.
This time my project is conclude the scientific python backend for Cantor. I began the development of this piece of software during LaKademy. The communication between Cantor and python is working properly. The software miss some features of IDE, like tab-complete and syntax highlight. I intent provide support to scipy, numpy and matplotlib too. Alexander Rieder, from KDE, is my supervisor.
There are some ideas about how to implement tab-complete and syntax highlight. It is possible using XML files (like I implemented in Scilab backend) or use the Kdevelop technology. I am researching which I will use.
More updates will come soon! Follow the tag gsoc2013-python-backend this blog!
This is just a manner of speaking. = D
I started contributing to Mageia since the early days of the project, translating the manifesto to Portuguese. Since then I helped on forums, IRC, mailing lists, got mirrors with high performance in Brazil, and did more work in promotion. However, I wanted to provide software for Mageia, because this is a job who not everyone can contribute.
To become a packers I had to participate in a mentoring program where I was guided by my Portuguese friend José Jorge or zezinho. I learned a lot about the art of creating RPM packages. Thanks zezinho!
Well, this is my way to contribute to free software. Thank you, community!
In the night of May 18, mages, sorcerers, witches, and fairies took from the cauldron the new stable release of Mageia, now in your third version.
Mageia is a community Linux distribution based on Mandriva. This version have several softwares in their recent versions: KDE 4.10.2, GNOME 3.6, XFCE 4.10, Linux 3.8, systemd 195, rpm 4.11, LibreOffice 4.0.3, and more.
This release is dedicated to Eugeni Dodonov, former employer in Mandiva and a great free software developer. In your last work, Dodonov was in Intel developing a better integration between Intel graphics cards and Linux kernel. Dodonov died very young. He was cycling when was hit by a car. This accident happened in Sao Carlo city, Brazil, in 2012.
This release is special for me because the packages that I am the maintainer are available for Mageia users now. I am packing SWI-Prolog and abnTeX2. I intend make packages for scientific softwares and KDE stuff like themes and plasma applets. And, maybe, make a package to Cave Story because it is a beautiful game and everyone must play it! =)
Release notes, download link, tutorials to update from Mageia 2, and more news are here.
Several Linux distributions have specific commands to download build requires of a package. For example, Debian and its derivatives have apt-get build-dep; in OpenSUSE is zypper si -d; Fedora have yum-builddep; etc.
The command is:
urpmi –buildrequires <package.src.rpm>
Remember, there are two hyphens in buildrequires option. You must to substitute <package.src.rpm> for the src.rpm package address. For example, to download Choqok build requires you uses::
urpmi –buildrequires ftp://mageia.c3sl.ufpr.br/mageia/distrib/cauldron/SRPMS/core/release/choqok-1.3-5.mga3.src.rpm
To find the SRPM package you must visit a repository of your distro and copy the complete package name. For example, there is a Tier 1 repository to Mageia in C3SL, the link is http://mageia.c3sl.ufpr.br/mageia/distrib/cauldron/SRPMS/.
