Enhance Formula Shape
Motivation for Proposal / Goal:
Being able to add formulas is a requirement for many users of an office suite like teachers or scientists. Although most of the later use LaTeX for this, when you need a lot of manual layout, a program like kword is a better choice.
Koffice in Version 1.6 included a very good formula editor. The port to the new flake architecture in Koffice 2.0 is very incomplete and lacks several features. Especially the user interface needs a lot of work. I would like to add support for navigating and editing a formula, as well as inserting various mathematical elements like Greek letters.
Additionally I would like to work on the loading and saving of MathML, which is used in ODF for storing formulas, or add the possibility to enter a certain subset of LaTeX.
For the editing part, I will add the missing logic in FormulaCursor and KoFormulaTool as well as implement the missing methods in the classes, that represent the MathML elements. For inserting mathematical objects I will select useful MathML templates and add a possibility to insert them to the tool docker.
There should be a possibility to insert (this list is not necessarily complete):
fenced elements (braces, brackets, ...)
super- / subscript
operator symbols (small / big)
under / over bars
3 weeks getting keyboard navigation working
3 weeks add mouse interaction, drag&drop, selecting and moving elements
3 weeks design and implementing the ToolWidget for inserting elements and changing there style
2 weeks improve the loading of MathML, get more unit tests to pass
1 week clean up the code, add missing documentation
Do you have other obligations from late May to early August (school, work, etc.)?:
I will have university until end of July, but I will have a very low course load, basically only one seminar and two lectures.
For the same reason, I would also be able to start coding earlier.
Apart from that I hope to be a guide at the International Mathematical Olympics at the end of July but this will take only one and a half week.
Finally in August I may start a Hebrew course, but this will nevertheless allow me to finish the project.
About Me (let us know who you are!):
the Technical University of Dresden. I have experience programming in C++ with QT from I am a student of mathematics and computer science in my last year at various university projects. I started using Linux and KDE around 7 years ago. Apart from writing a small patch for Canorus (www.canorus.org) I have never before programmed for an open source project. But I am already reading koffice-devel for a year andso I think I could find into the project relative easily.
In my free time I like to play trumpet, bike, travel, do stuff with my friends, my girlfriend and the guys from my church.
