Please help with the triage of [https://savannah.gnu.org/bugs/?group=octave existing bugs] to populate the list of easy bugs below. 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. | |||

Sometimes a standalone file or a diff file is submitted; Octave maintainers prefer a changeset though; preparing a changeset will expedite bug fixing. | Sometimes a standalone file or a diff file is submitted; Octave maintainers prefer a changeset though; preparing a changeset will expedite bug fixing. | ||

== Missing functions == | == Missing functions == | ||
* | * There are lists of missing functions for [[:Category:Missing functions|several packages]]. | ||
** It | ** 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. | ||
* openfig/savefig functions | |||
** These should be particularly easy additions as they are really just a wrapper on top of hgload/hgsave. | |||
== Function Compatibility == | |||
A number of functions are implemented, but may have known incompatibilities or only partially handled option sets, etc. | |||
* integral - currently cannot handle all optional inputs, see see {{bug|42037}} | |||
== BIST tests == | |||
Write Built-In Self Tests (BIST) for a function. This improve's Octave's regression testing and ensures that we don't break anything when we add new features. Tests are written in the Octave m-file language and usually take less than 10 minutes to code for a single instance. | |||
* [[Add_BIST_tests_for_octave_functions_written_in_C%2B%2B| BIST for C++ functions]] | |||
* [[BIST_for_m-files| BIST for m-files]]. See also [[Projects#Tests]]. | |||
== Miscellaneous == | == Miscellaneous == | ||
* C++ cleanup of packages after the switch to exceptions (late 2015).See [[Invert if/else/error]]. | |||
* 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. | * 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).

* Use non-empty identifiers in all warnings and errors issued by Octave; see {{bug|39439}}, {{bug|39434}}. 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 [http://octave.sourceforge.net/octave/function/warning_ids.html warning_ids] and [http://octave.sourceforge.net/octave/function/error_ids.html 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. | ** When raising errors and warnings try to use the ids that are documented in the functions [http://octave.sourceforge.net/octave/function/warning_ids.html warning_ids] and [http://octave.sourceforge.net/octave/function/error_ids.html error_ids].
