[Octave-bug-tracker] [bug #52479] textscan ignores leading spaces when creating cell from string/file

[Rik]

Update of bug #52479 (project octave):

              Item Group:              Regression => Matlab Compatibility   
                  Status:               Need Info => In Progress            
                 Release:                   4.2.1 => dev

Follow-up Comment #12:

I checked in the change on stable here
(http://hg.savannah.gnu.org/hgweb/octave/rev/ddc91a2ee0e0).  That still leaves
a problem when the delimiter is specified in a cell array, rather than as a
single character.  When specified as a single character, the code works.


octave:1> a = "\t\ta\tb\tc\n";
octave:2> textscan(a, '%s', 'delimiter', sprintf('\t'))
ans =
{
  [1,1] =
  {
    [1,1] = 
    [2,1] = 
    [3,1] = a
    [4,1] = b
    [5,1] = c
  }

}


But when the same character is presented as part of a cell array it is one
entry too short.


octave:4> textscan(a, '%s', 'delimiter', {sprintf('\t')})
ans =
{
  [1,1] =
  {
    [1,1] = 
    [2,1] = a
    [3,1] = b
    [4,1] = c

  }

}


Someone want to take a look at that?  It is no longer a regression, so I'm
changing the report status to "Matlab Compatibility".
