[Octave-bug-tracker] [bug #51035] Matlab/Octave incompatiblity for querying compact/loose display status

[Julien Bect]

Follow-up Comment #2, bug #51035 (project octave):

Oooops, I missed bug reports #49951 and #46034, which were indeed about the
same issue...

Apologies for not searching properly for prior bug reports.  Feel free to mark
this ticket as duplicate.

The situation is indeed unclear in Matlab's documentation, since 

1) on the one hand, the 'FormatSpacing' property has been officially removed
from the root properties in R2014b according to the release notes

http://fr.mathworks.com/help/matlab/release-notes.html?searchHighlight=FormatSpacing&s_tid=doc_srchtitle

BUT

2) The syntax


fmt = get (0, 'FormatSpacing')


is still officially documented as the proper way to get this information

http://fr.mathworks.com/help/matlab/ref/format.html

Judging by your comment on bug report #46000 (2015/09/22) this was already
mentioned on the exact same page back then.

-----

To summarize:

The 'FormatSpacing' root property seems to have always been de facto (if not
publicly) available in Matlab, and the syntax get(0,'FormatSpacing') appears
to never have been removed from Matlab's doc.

The syntax get(0,'FormatSpacing') was working in Octave as well, up to release
4.0.3.

I have to confess, then, that I really don't understand the decision to remove
this syntax from Octave 4.2.1.
