=== | === Octave 6.4 / 7 / 8 === | ||
* Discussion how to continue with the development. | |||
** jwe wants to introduce breaking changes (see below). | |||
* Octave should stick with the ~yearly major release cycle | |||
** Probably no Octave 6.4 (only if severe bugs occur). | |||
** Octave 7 (default branch) | |||
*** Should no longer receive "very" breaking changes (e.g. String-class for Octave 8) | |||
*** Has about 305 bugs fixed (not 100% reliable figure) and should not wait another year until many bigger outstanding changes happen (will be deferred to Octave 8) | |||
*** Tentative plan: | |||
**** November 2021 merge default to stable. | |||
**** End of 2021 release of Octave 7 | |||
** Octave 8 (new default branch) | |||
*** No clear decision how to handle very breaking changes until November 2021 merge default to stable. Depends on future needs. | |||
=== Octave 7 / 8 === | |||
* [https://www.mathworks.com/help/matlab/ref/arguments.html Function argument parsing] (introduced in Matlab R2019b, rather new) | |||
** jwe will continue to work on this feature on Octave 7 (default branch) | |||
** If feature cannot be completed by the end of the year, it will be disabled on parser-level (error), and introduced in Octave 8 one year later. | |||
* New GUI command widget | |||
** Possible to introduce it as user opt-in in Octave 7 | |||
** Pending issues: | |||
*** Command-widget does not look like the previous one (textbox for command input) | |||
*** jwe needs better looking widget (avoid developing a new one) | |||
*** No possibility to run external applications (like emacs, pager), which is already partially broken now. Need to implement own paging strategy (scroll bars, etc.) | |||
* Deprecation of Octave operators | |||
** Improve Matlab compatibility | |||
** Some extensions make it painful to implement Matlab compatible command-style function calls? (some clarification needed) | |||
*** Remove rarely used extensions like "**" power. | |||
*** Discussion about removal of "+=", "++", etc. No final decision made. | |||
*** Often used extensions like "!" == "~" must probably stay. | |||
=== C++ shared pointer / liboctave === | |||
* jwe had a look at Octave own reference counting | |||
* Wish to replace it with C++ shared pointers | |||
* Expert knowledge wanted! | |||
** jwe will reach out on Discourse about the exact problems. | |||
* jwe identified "copy expensive" inefficiency about mxArray to octave_value conversion? (some clarification needed) | |||
** Root of the trouble lies in historical handling of complex data?? (some clarification needed) | |||
