[Octave-bug-tracker] [bug #50640] display function not passing arguments to overloaded version of function

[Rik]

Follow-up Comment #32, bug #50640 (project octave):

We're actually getting very, very close.  I switched to overloading disp,
rather than display, and now Octave's built-in display function takes care of
handling compact/loose format.  See this cset
http://hg.savannah.gnu.org/hgweb/octave/rev/f04f32f08590.

This cset also fixed up inputParser which had been broken somewhere along the
way.

The issue remaining is that the built-in display should add a newline after
calling disp() for whatever object it is handling.

This works for built-in objects as shown below.


octave:2> x = magic (3);
octave:3> display (x)
x =

   8   1   6
   3   5   7
   4   9   2

octave:4> disp (x)
   8   1   6
   3   5   7
   4   9   2
octave:5> 



octave:5> x = audiorecorder ();
octave:6> display (x)
x =

audiorecorder object with properties:

  BitsPerSample =  16
  CurrentSample = 0
  DeviceID = -1
  NumberOfChannels =  2
  Running = off
  SampleRate =  44100
  TotalSamples = 0
  Tag = 
  Type = audiorecorder
  UserData = [](0x0)
octave:7> disp (x)
audiorecorder object with properties:

  BitsPerSample =  16
  CurrentSample = 0
  DeviceID = -1
  NumberOfChannels =  2
  Running = off
  SampleRate =  44100
  TotalSamples = 0
  Tag = 
  Type = audiorecorder
  UserData = [](0x0)
octave:8> 


To temporarily get things to work I added an extra newline in the disp.m
routines for old-style class objects (@audioplayer, @audiorecorder, @ftp). 
The new-style classdef class objects like inputParser already work correctly
(why?  Who knows).
