| ==== Previous idea collections for Octave 7 ====
| | * Not only providing major releases that "fix Matlab incompatibilities". |
| * [[:Category:Development#Goals_for_upcoming_releases]] | | * Great new features for a great new release. |
| ** [[JWE Project Ideas]] | | * Code sprints. |
| ** [[GUI terminal widget]]
| |
| * Discourse https://octave.discourse.group/t/goals-for-the-next-release/358
| |
| ** https://octave.discourse.group/t/new-command-window-widget/501 | |
|
| |
|
| ==== How to make Octave 7 visibly special? ====
| | Some idea collections so far: |
| | * "jwe priorities" in [[:Category:Development#Goals_for_upcoming_releases]], see also [[JWE Project Ideas]] |
| | ** Bug fixes, especially those related to compatibility issues. |
| | ** Work through the open bug reports for which patches have been submitted. Review/apply/reject and close as many of these reports as possible. |
| | ** Refactor/rewrite code for handling load path. |
| | ** Refactor/rewrite exist and which functions. |
| | ** Create a low-level interface to HDF5 functions. |
| | ** Support Matlab's HDF5-based MAT file format using the proposed low-level interface to HDF5 functions. |
| | *** Allow all types of function handles to be saved and loaded. |
| | *** Allow [[classdef]] objects to be saved and loaded. |
| | ** Replace the [[GUI terminal widget|terminal widget in the GUI]], see also https://octave.discourse.group/t/new-command-window-widget/501 |
| | ** Accept Matlab's new argument validation syntax in parser. |
|
| |
|
| * Implement Matlabs new String-class | | * Discourse https://octave.discourse.group/t/goals-for-the-next-release/358 |
| ** Difficult, but highly demanded.
| |
| * Builtin hash-operator
| |
| ** Distinct feature from Matlab
| |
|
| |
|
| ===== Improve graphics ===== | | == Ideas for next meeting == |
|
| |
|
| * Use "new" OpenGL code path
| | === Topic suggestions === |
| ** Nice overview by [[User:Hg200]]
| |
| ** Likely to make plotting faster (more efficient methods to move data to graphics card)
| |
| ** Does '''not''' solve "double precision" problem, scaling must happen on Octave side even with new OpenGL code path
| |
| * Consult professional OpenGL developer to review code
| |
| ** General agreement to spend Octave project money on this
| |
| | |
| ===== Implement Matlabs new input validation ===== | |
| | |
| * jwe can create dummy tree-elements
| |
| ** Problem if values are evaluated, the "right" action must be done
| |
| * Can those validation statements come at arbitrary positions or only at the beginning of the file?
| |
| | |
| ===== Command Window Widget =====
| |
| | |
| * [[GUI terminal widget]], https://octave.discourse.group/t/new-command-window-widget/501 (jwe's patch!)
| |
| * Of special interest for MS Windows users
| |
| * Unify widget for all OSes
| |
| * Make jwe's patch a configurable options for testing (nothing to use productively yet)
| |
| * Need to implement own pager (alternatively: scroll bar only)
| |
| * Better responsibility delegation between GUI and interpreter
| |
| ** Big matrix output: interpreter could ask GUI to print big matrix, GUI could confirm with user, etc.
| |
| ** Formatting (colors, URLs, etc.) could be done by the GUI. Interpreter does not need to know about window-width, etc.
| |
| | |
| ===== Backend code improvements =====
| |
| | |
| * "Ditch" old UNIX system functions (e.g. popen)
| |
| ** Move to package?
| |
| ** compose a list of functions that are candidates for removal from core Octave. See: [https://octave.discourse.group/t/moving-posix-system-call-and-library-functions-out-of-core-octave/1027 Moving POSIX system call and library functions out of core Octave]
| |
| * performance of symbol lookup
| |
| ** use <code>std::unordered_map</code>, rather than <code>std::map</code> to increase performance (e.g. of interpreter lookups)
| |
| ** Potentially implement "import" keyword? That would probably slow down symbol lookup some more.
| |
| * Replace custom reference counters with implementation using <code>std::shared_ptr</code>
| |
| ** Some instances are more difficult to replace. jwe will post something about this on the discourse forum.
| |
| * favor C++ std-library functions over gnulib where possible
| |
| ** Maybe require C++14 or C++17? See: [https://octave.discourse.group/t/using-c-17-features/1026 Using C++17 features]
| |
| * improve HDF5 integration
| |
| ** Add "wrapper" for libhdf5 functions in Octave's scripting language.
| |
| ** Key to support latest Matlab file formats. Try to implement in the interfaces for that format in .m file functions.
| |
| ** Some developers very interested in this!
| |
| | |
| ==== Testing Matlab code ====
| |
| | |
| * jwe will a single Discourse thread to ask for tests in Matlab
| |
| ** Old Discourse threads many maintainers receive notifications.
| |
| | |
| ==== Octave online service ====
| |
| | |
| * Similar to Matlab online
| |
| * There are already existing services
| |
| ** https://cocalc.com/doc/octave.html
| |
| ** https://octave-online.net/
| |
| * In general Jupyter-Notebook based solutions are already highly developed
| |
| * Running an own service lacks of manpower and financial resources
| |
| | |
| ==== Documentation ====
| |
| | |
| * Split Octave manual https://octave.org/doc/latest into
| |
| ** Function reference, like Octave Forge https://octave.sourceforge.io/docs.php
| |
| *** Need knowledge how it was created (Kai looks at this again)
| |
| *** Once succeeded, hosted at https://octave.org/doc/
| |
| ** Usage manual (like the current one, more detailed, without @docstrings)
| |
| | |
| == Ideas for next meeting ==
| |
|
| |
|
| * Automatically reschedule the meeting monthly (Kai suggests on Discourse) | | * ... |
| * MXE Octave branches and buildbots
| |
| * Strategy for transition to string class syntax (incompatible to current double-quoted character vectors in Octave)?
| |
| * Allow using more modern C++ dialects (C++17 STL std::filesystem or boost::filesystem)?
