Short projects

From Octave
Jump to navigation Jump to search

This is a list of small projects, the type that could be done in a couple of hours, maybe even minutes (no promises, we should all know about how estimates for software development work). This is probably the best place for users who want to start helping with Octave development (please, see also Octave coding guidelines). Please submit a patch to the patch tracker (not to the mailing list) and add a link to the item in question.

The list is meant to be dynamic, please add, remove, and comment on it. And since the things are likely to be of short duration, don't ask if is there is anyone already working on it. Projects of long duration should be added to the Projects page instead.

Bugs

Warning icon.svg
do not simply add a patch/file to the bug tracker. Always leave a comment at the same time, even if it just a simple "I prepared a change that should fix it". If there is no comment, it's hard to notice that a patch was added since there will be no notice on the discussion about it.

Most of the small and easy bugs are caught and fixed quickly by the Octave developers. The best way to catch an easy one is then to to the bug tracker (note that this has a lot of activity so you'll probably prefer to receive a digest).

Please help with the triage of existing bugs to populate this list.

  • #41186 image: fspecial disk is not matlab compatible
    • this should be easy very easy to fix. The only complicate part is figuring out how Matlab does the calculations (since that is not documented). Needless to say, you cannot borrow from Matlab's source code!
  • #41484 change error message from validatestring to follow Octave guidelines
    • this is a very very easy fix. Things can't get easier than this. Only reason why Octave developers haven't done this themselves was to give an entry point for someone new to Octave development.
  • #41476 listdlg() doesn't allow scrolling in the window
    • There is a proposed fix in the bug report. Just need to make the modification and verify that everything else still works.
  • #41773 "imshow (im , 'xdata', [-5 5], 'ydata', [-5 5])" fails
    • This is a very simple input checking problem.

Missing functions

  • conversion between units of length and angles for the mapping package (please see #8371, #8372, and #8373 first)
    • sm2deg
    • sm2rad
    • nm2rad
    • km2rad
    • rad2km
    • rad2nm
    • rad2sm

Miscellaneous

  • Use "units.h" in units (function from miscellaneous package) rather than making a call and parsing its output (and having to handle multiple versions of it). This change will make it much more robust. Should be very simple but requires knowledge of C (units is written on C) and C++ to write its Octave interface.
