[Octave-patch-tracker] [patch #8783] C++ implementation of textscan

[Philip Nienhuis]

Follow-up Comment #72, patch #8783 (project octave):

Hi Lachlan:
Never mind comment #71, ytextscan has no FAILs on Windows. Sorry for the
noise.

I've been amending (weeding) strread to have (y)textscan() as a backend. To be
consistent :-) I've provisionally renamed my dev strread to "ystrread.m"
(attached). That is still a work in progress, as you'll understand.
The tests are still in place with "strread" replaced by "ystrread" to find out
how far ytextscan can serve as backend for (y)strread.

I ran into the issue that ytextscan as it stands (files 36288 and 36566) still
doesn't properly seem to process uneven column lengths:

>>  [a, b] = strread ("10 a 20 b\n 30 c 40", "%d %s", 4);
## Note strread.m !!!
>> b
b =
{
  [1,1] = a
  [2,1] = b
  [3,1] = c
}
>>  [a, b] = ystrread ("10 a 20 b\n 30 c 40", "%d %s", 4);
#### with ytextscan as backend
>> b
b =
{
  [1,1] = a
  [2,1] = b
  [3,1] = c
  [4,1] =
}
>> C = ytextscan ("10 a 20 b\n 30 c 40", "%d %s", 4);
>> C{2}
ans =
{
  [1,1] = a
  [2,1] = b
  [3,1] = c
  [4,1] =
}
>>


(Note the lack of trailing EOL in the text string - see comment 9. 10 and
46.)
