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.

Another way to catch a small project is to [https://lists.gnu.org/mailman/listinfo/octave-bug-tracker subscribe to the bug tracker] (note that the bug tracker has a lot of activity).  You may find it useful to review the [http://wiki.octave.org/wiki/index.php?title=Short_projects&action=history history] of this short projects page, to give you an idea of past successful short projects.

* {{bug|39439}}, {{bug|39434}} - Use non-empty identifiers in all warnings and errors issued by Octave
 
** You may tackle as many or as few IDs as you have time for. As it is a widespread issue, finding occurrences in the source code should give you valuable knowledge about the way Octave files are organized.  When raising errors and warnings try to use the ids that are documented in the functions {{manual|warning_005fids|warning_ids}} and {{manual|error_005fids|error_ids}}.  If you really need a new id (please, first read the ones already there!), please add it to those functions as well.  If you see other ids used in core that are not given by the functions mentioned above, please, report or submit patch for them, in addition to the patch to the calling functions as well.

** It would help to group the missing functions in the [[image package]], as per [http://www.mathworks.com/help/images/functionlist.html] (similar to what was done in the [[signal package]] wiki page); please keep the original alphabetical list intact.

** These should be particularly easy additions as they are really just a wrapper on top of hgload/hgsave.

A number of functions are implemented, but may have known incompatibilities to Matlab or only partially handled option sets, etc.

Sometimes a standalone file or a diff file is submitted; Octave maintainers prefer a changeset though; preparing a changeset will expedite bug fixing. See the [[Mercurial]] and [[Commit message guidelines]] page how to do it.

* Use "units.h" from [http://www.gnu.org/software/units/ GNU units] in [http://octave.sourceforge.net/miscellaneous/function/units.html function units] (from the Octave-Forge [http://octave.sourceforge.net/miscellaneous/ miscellaneous package]) rather than making a system call and parsing its output (and having to handle multiple versions of it). This change will make it much more robust. It likely will alleviate the requirement of having [http://www.gnu.org/software/units/ GNU units] installed in the system separately by the user. This requires knowledge of C (units is written on C) and C++ to write its Octave interface. It can be very easy if the units.h truly allows to be used as library or maybe impossible if it does not. This has not been investigated yet.
