[Octave-bug-tracker] [bug #50855] new Matlab string array syntax and string class

[Guillaume]

Follow-up Comment #10, bug #50855 (project octave):

Noticing a string class was again discussed in the last developer meeting:

https://octave.discourse.group/t/octave-developer-meeting-october-2022/3512


A particular focus was on the string class (again). It might be a candidate
for an early addition during the development cycle of Octave 9 (taking
leverage of @apjanke’s .m file implementation in the tablicious package).
Having that might allow adapting a range of functions to accepting string
objects early on (even if a “final” implementation of the string class
might be in C++). Decisions for how to transition to the new syntax for double
quotes still need to be taken.


I think adding the functions from comment #8 would already be useful for
compatibility with Matlab code. Function isstring () could also be modified to
be ready for a string class:


-  tf = false;
+  tf = isa (s, "string");


Also attaching my earlier work on a string class with BISTs. Methods needed to
be implemented are commented out in the file. They should probably better be
added as separate files, e.g., @string/matches.m.
