[Octave-bug-tracker] [bug #47908] Octave:classdef-to-struct not shown by warning_ids.m

[Lachlan Andrew]

Follow-up Comment #4, bug #47908 (project octave):

Reading between the lines in comment #2 suggests that jwe thinks that it is
not necessary to document all warnings.

I think it is important to have a clear statement of what the warning means,
beyond the usually brief messages.  For example, suggesting alternative idioms
to replace discouraged ones would be useful.  Even if this isn't all in one
place in warning_ids.m, it should IMHO be somewhere.

I agree there is little point in entries like


'Octave:singular-matrix'
'Octave:nearly-singular-matrix'
     By default, the 'Octave:nearly-singular-matrix' and
     'Octave:singular-matrix' warnings are enabled.


but entries like 


'Octave:str-to-num'
  If the 'Octave:str-to-num' warning is enabled, a warning is printed
  for implicit conversions of strings to their numeric ASCII
  equivalents.  For example,
    "abc" + 0
     => 97 98 99
  elicits a warning if the 'Octave:str-to-num' warning is enabled.
  By default, the 'Octave:str-to-num' warning is disabled.


is really useful.
