The following are projects that I would like to work on, roughly prioritized by my level of interest.  I intend to provide expanded explanations for each of these items.

Implement Matlab compatible HDF5-based load and save functions.


=== External editors ===
* Make the load and save commands compatible with Matlab's HDF5-based file format.  Matlab users expect this and we need something like this to support large arrays anyway.  As much as possible, the initial implementation should be written in Octave's scripting language and the proposed Low-level interface to HDF5 functions so that it can easily be updated and patched as needed while we are still working out the details.  Only later should we consider translating performance-critical parts to C++, and then, only if really necessary.
* Phase out Octave's own text and binary formats.  Too much effort is required to maintain the code to support all the various formats.
* Low-level interface to HDF5 functions.  Create a thin wrapper for the HDF5 library.  As much as possible, make it compatible with the [https://www.mathworks.com/help/matlab/low-level-functions.html Matlab interface to HDF5].  However, we may support newer functions (as of 2020/10/30, the list of Matlab functions appears to correspond to an older version of the library than is presently available in the HDF5 library itself) and support for legacy functions has a low priority.
 
== External editors ==


Make it possible to use external editors such as Emacs, vim, or others with the GUI in addition to Octave's built-in code editor.

== Windows distribution ==
Eliminate the following msys packages.  Some might be removed
entirely if they are unnecessary for running Octave or building
Octave Forge packages.  Otherwise, we should be building them from
source as we do all other tools and libraries that are distributed
with Octave.  The difficulty is that although the msys packges are
typically based on old versions of these packages, they sometimes
have fixes that are needed to allow them to run properly on
Windows systems.  Note also that we distribute a termcap library,
but the msys version of less depends on the msys termcap library.
